Line Manager Training for Small Businesses in the UK: How to Develop Managers Who Can Actually Manage

Something we keep seeing in growing businesses is that somebody becomes a manager because they are very good at their job. They know the clients. They know the work. They understand the business. People trust them. Giving them responsibility for a team feels like the obvious next step.

Then their job changes almost overnight.

They are no longer responsible only for their own work. They are having conversations about performance, absence, behaviour, pay, progression, workloads and priorities. They are managing people who may have been their peers a month earlier. They are expected to give feedback, delegate properly, deal with disagreements and spot when somebody needs support.

And quite often, nobody has ever taught them how to do any of it.

The Chartered Management Institute found that 82% of managers who enter management positions have received no formal management or leadership training. Its research, conducted with YouGov and involving more than 4,500 people across the UK economy, describes these people as accidental managers.

82%, That is a lot of people being given responsibility for somebody else's working life and being expected to work the rest out as they go.

For small and growing businesses, we think this matters particularly because managers tend to sit so close to everything else happening in the company. One line manager might be responsible for six people, several clients, a large chunk of revenue and half a dozen operational decisions before lunch.

Good management development is not about turning those people into textbook managers.

It is about giving them enough knowledge, confidence, practice and support to handle the situations already appearing in front of them.

Why line manager training matters more as a small business grows

There is a point in the growth of many businesses when the founder can no longer manage everybody directly.

It is usually a good problem to have.

The team has grown. There are more clients, more work and more opportunities. New layers of responsibility appear because they have to.

But this is also the point at which the day-to-day experience of working in the business starts to depend much more heavily on its managers.

The CIPD's 2025 Good Work Index found that employees who viewed their line managers more positively were more likely to feel competent and effective at work, less likely to say their job negatively affected their health and less inclined to consider leaving their organisation. The CIPD also noted that more managers were reporting having the time, training and information they needed to manage people well.

That connection makes sense to us.

Policies matter. Values matter. Benefits matter.

But an employee's experience of all of those things is often delivered through one person. Their manager.

A brilliant parental leave policy feels rather different if somebody is nervous about telling their manager they are pregnant.

A carefully designed performance process achieves very little if managers avoid giving feedback until something has become a serious problem.

A company can talk about development as much as it likes, but if nobody is having proper career conversations, employees will draw their own conclusions about whether there is a future for them.

This is why line manager training for small business UK teams should not sit in a folder labelled learning and development and only appear when the training budget is being discussed.

Management capability becomes part of how the business operates.

The first-time manager problem is not a lack of intelligence

We have worked with managers at every stage of their careers, and there is something worth saying here.

Most new managers know that managing people is different. They are not oblivious to it.

What they often have not had is enough opportunity to practise the difficult bits before being expected to do them for real.

Imagine somebody who has been an excellent senior specialist for four years.

They know how to handle a difficult client call because they have probably done it dozens of times. They know when to push back, when to listen, what questions to ask and when an issue needs escalating.

Then they become a manager and a member of their team starts missing deadlines. Suddenly the conversation feels completely different.

Is this poor performance? Is something happening outside work? Have expectations been clear enough? Should the conversation be documented? When does informal management become a formal process? What can they ask? What should they not ask?

That manager does not need a lecture on leadership. They need the chance to work through a situation that looks remarkably like the one waiting in their diary on Tuesday morning.

That is what good first-time manager training for small business UK employers should be designed around.

What Acas includes in training for new managers

Acas's current foundation training for new managers covers the role of the line manager, communication, absence, discipline and grievance, and basic equality law. It is specifically aimed at people moving into management, including those who have been promoted and are now managing former peers.

That last situation deserves more attention than it sometimes gets. Going from colleague to manager changes relationships.

Yesterday, two people might have complained to one another about a deadline. Today, one of them has to explain why it still needs to be met.

A friend at work may suddenly become somebody whose performance needs discussing. The new manager has not changed as a person, but their responsibilities have.

Training gives them somewhere to think through that difference before every decision becomes a live experiment.

What people management skills do line managers actually need?

There is no shortage of management models. Some are useful, and some less so.

But when we think about people management skills for line managers in the UK, we tend to come back to the things managers actually spend their weeks doing.

Giving feedback before an issue becomes a problem

Managers need to be able to tell somebody what is going well and what needs to change.

That sounds incredibly basic, but it is also one of the things people put off constantly.

We understand why. Giving somebody difficult feedback can feel uncomfortable, particularly for a manager who values having a good relationship with their team.

But avoiding the conversation does not protect the relationship.

Usually it creates a stranger version of it, where the manager knows there is a problem and the employee does not.

Then three months later the employee hears that their performance has been below expectations for some time. That is unfair on both people.

Good management development gives managers a way to practise direct, specific conversations without turning every piece of feedback into a formal event.

Managing conflict before everybody takes a position

Conflict is another good example of why management development needs to be practical.

Acas worked with researchers from the Universities of Westminster and Sheffield on an Economic and Social Research Council-funded study into conflict management. The project initially worked with 150 managers across five organisations and later reached more than 1,000 managers.

The researchers used training built around conversations, performance and misconduct, potential conflict and team conflict.

The results are worth looking at.

64% of managers in an Acas sub-study involving small businesses were less likely to avoid conflict after the training.

69% adopted a more problem-solving approach.

80% said they intended to change the way they managed their team.

Then the researchers looked at what employees experienced.

In the main randomised controlled trial, staff working for trained managers reported an improvement in managers' willingness to step into conflict at the right time compared with staff whose managers had not received the training. Employees of trained managers also reported a reduction in work-related stress that was not seen in the control group.

That is the part we find particularly interesting.

The point of manager training is not that managers complete training.

It is that somebody on their team notices a difference.

Having proper performance conversations

Performance management can become far more complicated than it needs to be.

At its heart, somebody needs to know: What am I responsible for? What does good look like? How am I doing? What needs to change? What happens next?

Managers need enough confidence to answer those questions honestly.

This is also where good management and good HR processes meet. Managers do not need to become employment lawyers, but they do need to understand when a normal performance conversation is enough and when they should get advice.

Delegating instead of holding on to everything

This one appears constantly in growing founder-led businesses. A technically excellent employee becomes a manager, but they remain the technically excellent employee as well.

So they manage the team and continue doing large parts of the team's work. It makes perfect sense at first. They can do it faster. They know exactly how it should be done. There is a deadline.

But over time, the manager becomes the bottleneck and the team never gets the opportunity to build capability. Learning to delegate is not really about distributing tasks.

It is learning which decisions somebody else can make, how much context they need and how a manager can stay accountable without staying involved in every detail.

Supporting people without trying to solve everything

Managers are often the first people employees speak to when something is wrong.

Sometimes the issue is work. Sometimes it is health. Sometimes it is something happening at home that has started affecting work. Managers need to know how to listen, what support the business can offer, when confidentiality has limits and when they need HR advice.

They do not have to become therapists. They do have to become comfortable enough with difficult conversations that employees are not left wondering whether it was a mistake to say anything.

How to develop line managers in a UK small business

One of the problems with management training is that businesses can treat the event itself as the development.

Six managers attend a workshop. Everybody enjoys it. There are some good conversations. Then everybody goes back to work.

Three weeks later, the slides are sitting in somebody's Downloads folder and Tuesday still looks exactly like Tuesday did before.

The CIPD's management development factsheet takes a broader view. It covers identifying managers' development needs, connecting development to business strategy, selecting development techniques and evaluating programmes afterwards.

We think that sequence matters. Training should begin with the business, not the course catalogue.

Start with the situations your managers are actually dealing with

If a business has recently grown from 20 people to 45, its management needs may look very different from those of a stable 45-person company.

Perhaps half the managers are managing people for the first time. Perhaps teams have become hybrid. Perhaps the founders are still approving decisions that managers should now own. Perhaps performance conversations are inconsistent. Perhaps every difficult employee relations issue lands with one director because nobody else feels confident dealing with it.

That is useful information. A line manager development plan UK businesses can actually use should begin there.

Ask what managers are doing now, what they will need to do over the next year and where they are getting stuck.

Then build the development around those gaps.

Give managers knowledge, then somewhere to test it

Manchester Metropolitan University's Good Employment Learning Lab was created specifically to examine how line managers develop people management skills.

The programme worked with hundreds of managers across Greater Manchester, the North West and adult social care. Its approach included masterclasses, peer learning and coaching, with managers working on issues including conflict management, getting the best out of teams, recruitment and new ways of working.

The researchers did not treat knowledge alone as enough.

Their learning model included gaining knowledge, reflecting, making sense of it, experimenting and learning with other people. Their later evaluation also highlighted factors such as access, psychological safety and accountability.

We like that because it reflects what we see in practice. A manager can understand feedback perfectly in theory. Then they have to give it to somebody who becomes defensive. That is where the learning starts to become useful.

Build development into the working week

There is another finding from the Acas conflict research that small businesses should pay attention to. The main barrier managers reported was time and space for training.

The researchers responded by reducing the programme to core skills and creating flexible online learning that managers could complete in around three hours.

Small businesses rarely have the luxury of removing every manager from the business for days at a time. Fortunately, that should not be the standard anyway.

A management development programme might combine short workshops, live case discussions, coaching, peer sessions, manager toolkits, observation, practice conversations, follow-up sessions and HR advice when a live issue appears.

The combination matters more than making the programme enormous. We would rather see a manager practise one conversation properly and use it the following week than sit through six hours of theory they never return to.

Case study: what changed when conflict training became practical

The Acas and university research is useful because it tested whether training changed behaviour rather than simply asking whether managers liked the course.

More than 1,000 managers were eventually involved in the programme. The content focused on having better conversations and dealing with workplace conflict earlier.

Managers became more confident about stepping into conflict and more inclined to use problem-solving approaches. Employees then reported differences in how trained managers behaved.

There is an obvious lesson here for smaller employers. You do not necessarily need a huge management academy. You need development tied closely enough to real work that managers can use it. Conflict is a particularly good test because there is nowhere to hide. Either the manager has the conversation or they do not. Either the problem gets dealt with while it is still manageable or it grows.

Case study: a management framework becomes useful when it changes Tuesday morning

A 2025 UK Government case study looked at Stacey Killon, Head of Scientific Learning and Talent Management at the UK Health Security Agency.

When she took responsibility for her team, her two direct reports had been without a line manager for three months.

Her response was not an elaborate leadership programme.

She began with weekly team meetings.

Those meetings were used to review outputs, agree priorities, understand wider organisational objectives and give the team space to talk through what was happening. She used the Civil Service Line Management Standards as a framework for creating clearer shared purpose within the team.

It sounds almost too simple.

Weekly meetings. Clear priorities. Connecting somebody's work to what the organisation is trying to achieve.

But management is full of things that sound obvious when somebody writes them down and are much harder to do consistently in a busy week.

That is why we think management development works best when it changes habits, not vocabulary.

Case study: development is relevant to experienced managers too

Management training is sometimes positioned as something people need at the beginning of their career.

That misses quite a lot.

A 2024 UK Government case study followed HMRC senior IT delivery manager Nikki Fisher, who had 35 years of Civil Service experience and substantial line management experience before completing the Line Manager Induction Programme.

She used the programme as a chance to refresh and refine how she managed. One result was renewed attention to performance and development conversations and to the needs of individuals within her small team.

That is an important point.

Experience matters enormously.

But experience can also create habits.

Management development gives experienced managers somewhere to look again at how they are doing things, what has changed and what they may have stopped noticing.

Case study: development can change how somebody sees their own career

There is another interesting government example from 2026.

Ashley Jamieson at Social Security Scotland completed its Achieving Your Potential development programme after having previously held management responsibilities earlier in her career.

The programme gave her structured time to think about her strengths, working preferences and what she wanted next.

She subsequently applied for and gained a senior performance officer role and now manages a newly formed team of six.

Management development is usually discussed in terms of improving today's manager.

Sometimes it also shows somebody that they are ready to become tomorrow's.

For a growing business, that matters.

Recruiting managers externally is sometimes exactly the right answer.

But businesses should also know who inside the organisation could take on more responsibility with the right support.

What should a line manager development plan include?

We would keep it practical.

A useful line manager development plan for a UK business should answer five questions.

1. What do we expect our managers to do?

This sounds obvious, but job titles rarely answer it.

Are managers accountable for performance, development, absence, hiring, pay decisions, workload allocation, employee relations, team budgets or client relationships?

Be specific.

Managers need to know where their authority starts and stops.

2. What skills do they need to do those things well?

This is where the people management skills for line managers UK businesses need become clearer.

Typical areas include feedback, delegation, performance, conflict, communication, absence, inclusion, wellbeing, coaching and employment law basics.

Not every manager needs the same depth in everything.

3. Where is each manager now?

A first-time manager may need fundamentals.

An experienced manager might need help with coaching, organisational change or leading other managers.

Treating both people identically because they share a job grade wastes everybody's time.

4. How will managers practise?

This is the bit we would never leave out.

Give managers scenarios. Let them practise the performance conversation. Talk through the employee who keeps arriving late. Role-play the conversation with the brilliant employee who wants a promotion that is not available yet. Discuss what happens when somebody cries. Discuss what happens when somebody gets angry.

Real management contains awkward moments. Training should too.

5. How will we know it is working?

Completion rates tell you whether people attended.

They do not tell you whether management improved.

Look elsewhere.

Are problems being raised earlier? Are managers having regular one-to-ones? Are performance conversations clearer? Do employees know what is expected of them? Are managers escalating everything to founders or HR, or are they becoming more confident making appropriate decisions themselves? Has employee feedback changed?

The CIPD specifically includes evaluation as part of management development rather than treating programme delivery as the finish line.

We agree.

The founder's role changes when managers become stronger

There is another side to management development that gets less attention.

Managers cannot become accountable if founders keep taking the accountability back.

We see why this happens.

A founder hears about a client issue and knows immediately how they would solve it.

A manager makes a decision slightly differently from the way the founder would have made it.

There is a temptation to step in.

Sometimes that is necessary.

But if it happens every time, managers learn something quite quickly: difficult decisions still belong to the founder.

Then the founder wonders why everything keeps coming back to them.

Developing managers therefore involves developing the space around them too.

What decisions can they make? When should they consult? What genuinely needs approval? What happens when they make a reasonable decision that is different from the one a founder would have made?

Good management development should create more capable managers.

Good organisational design should then let them manage.

How JourneyHR can help with management development

We have delivered management and leadership training for more than 15 years, and our approach starts with the business rather than an off-the-shelf list of management theories.

We work with businesses to understand what their managers are dealing with, where capability gaps sit and what people will need as the company grows.

For some organisations, that means first-time manager training covering the fundamentals of managing people.

For others, it means developing experienced managers who need to become better at feedback, delegation, coaching, performance conversations, motivation or conflict.

Our bespoke management workshops can be delivered in shorter sessions across several months or in more concentrated formats, depending on what works for the business. The sessions use discussion, exercises and practical situations because people tend to learn management by doing it, talking about it and trying again.

We also offer open People Management Essentials workshops, covering areas including team motivation, HR fundamentals, difficult conversations, delegation, conflict and communication.

And where the question is bigger than training, we can work with businesses on the wider learning and development strategy too, including identifying capability gaps, setting development objectives and deciding what support should happen next.

The starting point does not need to be complicated.

Usually it is a conversation about what your managers are being asked to do now, what they are finding difficult and what the business will need from them next.

Final thought

We keep coming back to the same point with management development.

Being good at a job and being good at managing somebody doing that job are two different things.

The first does not automatically produce the second.

But management can be learned.

People can get better at feedback. They can become more confident handling conflict. They can learn when to coach and when to be direct. They can stop solving everything themselves. They can become better at the conversations they once avoided.

And when that happens, the difference is not confined to the manager.

Their team feels it.

The founder feels it.

Eventually, the business does too.

FAQs

What should line manager training for a small business in the UK cover?

Line manager training should reflect what managers are responsible for in that particular business. For many small UK employers, the core areas include communication, feedback, performance management, delegation, absence, difficult conversations, conflict, employee wellbeing, basic employment law responsibilities and knowing when to ask HR for support. Acas includes communication, absence, discipline and grievance, equality law and the responsibilities of a line manager within its training for new managers.

How do you develop line managers in a UK small business?

Start by identifying what managers are expected to do and where they need more support. From there, combine relevant training with opportunities to practise, peer discussion, coaching and follow-up. Research from Manchester Metropolitan University's Good Employment Learning Lab supports an approach where managers gain knowledge, reflect on it, make sense of it, experiment and learn with others rather than relying on classroom instruction alone.

When should a first-time manager receive training?

Ideally, development starts shortly before somebody takes responsibility for a team or very soon afterwards. That gives the new manager some basic tools before they encounter difficult performance, absence or conflict situations. It is particularly useful when someone has been promoted from within and is beginning to manage former peers.

How long should line manager training take?

There is no single correct length. The Acas conflict management research found that lack of time and space was a significant barrier to manager training, which led researchers to design a flexible programme that could be completed in around three hours. In our experience, several focused sessions with practice between them can sometimes be more useful than one long programme because managers have the opportunity to apply something at work and come back to discuss what happened.

How can a small business tell whether manager training has worked?

Do not rely only on attendance or course feedback. Look for changes in what managers and employees actually experience. That might include earlier performance conversations, better one-to-ones, fewer avoidable escalations, greater confidence dealing with conflict, clearer delegation and employee feedback about management quality. In the Acas research, employees were surveyed as well as managers, allowing researchers to identify changes in manager behaviour from the perspective of the people being managed.
