Everyone wants more apprentices. Who has time to teach them?

Construction needs its next generation. That means making room for the people who will teach them, as well as the people joining the trade.

Imagine this on a busy site: an apprentice is about to make a cut. The experienced carpenter beside them can see something is wrong.

There are two ways to resolve it. Take over, make the cut and move on. Or stop, ask the apprentice to explain their thinking, work back through the setting out and let them try again under supervision.

The first gets this piece of work finished sooner. The second might help someone get the next hundred right.

Now imagine the carpenter is already behind programme.

That small, hypothetical moment gets to the heart of a much bigger construction skills question. Everyone can agree that the industry needs more apprentices. Agreement becomes harder when developing one means changing what an experienced person can deliver today.

The person missing from the recruitment photograph

Apprenticeship announcements have an obvious subject: the new starters. Their enthusiasm deserves attention. So does the less photogenic commitment being made by someone further into their career.

They will explain things they can now do almost without thinking. They will watch someone work slowly. They will distinguish between a mistake that offers a useful lesson and a task that must be stopped immediately. They will find another way to explain something when the first explanation does not land.

That is skilled work in its own right.

In its 2026 to 2030 Construction Workforce Outlook, CITB estimates that the UK industry will need an average of 41,200 additional workers a year to meet forecast demand, including replacing people who leave. These are projected recruitment needs across the workforce, not a target for apprenticeship starts. But they make the scale of the task clear. CITB, Construction Workforce Outlook.

A place on a course begins a route into the industry. Developing someone who can exercise sound judgement takes sustained attention from people who already know the work.

Who has that attention available?

Teaching cannot depend on a quiet afternoon

For a small contractor, this question is painfully practical. The owner may also estimate jobs, order materials, deal with clients and do the work. There may be no spare supervisor to assign to development.

It would be easy to lecture that business about investing in the future. It would be more useful to ask what would make the investment possible.

Consider a crew whose daily workload assumes every experienced member is working at their normal pace. Add an apprentice, give one person responsibility for their learning, and leave the output expectation untouched. Something has to give.

Perhaps the experienced worker stays later. Perhaps explanations get shorter. Perhaps the apprentice is repeatedly given the tasks they can already do, because today is another bad day to try anything new.

These are possible consequences of that arrangement, not a description of every site. Many firms teach exceptionally well. The point is that a commitment to training becomes fragile when delivery depends on nobody needing to be taught.

If teaching has no place in the programme, it has to borrow time from somewhere else.

Being excellent at the trade is a starting point

Ask an experienced craftsperson why they have changed their approach and the first answer may be that the job simply needs it. Years of practice have compressed a chain of observations into a quick decision.

An apprentice needs help seeing that chain. What did you notice? What would have happened if you had continued? When would the usual approach have been appropriate?

This is why putting a learner beside the best person is not, by itself, a complete training plan. Will that person enjoy teaching? Can they explain their decisions? Do they have the patience, support and authority to slow a task down when learning requires it?

The Department for Education’s employer guidance for England recommends mentoring and regular guidance alongside workplace training. It also describes a separate mentoring role that gives an apprentice someone to approach beyond their line manager. Technical supervision and that wider support are related, but they need not come from the same person. Apprenticeships, support your apprentice.

That distinction matters in a small team. The person best placed to teach a practical technique may not be the person an apprentice feels able to tell that they are struggling.

Whose investment is it?

There is another uncomfortable conversation here. A subcontractor may carry the immediate cost of teaching while the benefits eventually travel across the industry.

The apprentice might move. The project might finish before their training does. The next contractor could benefit from skills developed on someone else’s time.

Employers cannot eliminate that uncertainty. But clients and main contractors can consider whether their expectations make training easier or harder. What happens to a promised learning opportunity when the sequence changes? Is mentoring recognised when a team discusses workload? Does the apprentice get exposure to the range of work their development needs?

There are ways to spread experience across employers. CITB describes shared apprenticeship services in which apprentices work on projects with more than one employer. Availability and arrangements need checking locally, but the model challenges the idea that one small business must provide every experience alone. CITB, types of apprenticeships.

Sharing the responsibility still requires coordination. A succession of placements is valuable when learning connects between them, rather than starting again at each gate.

Make the next useful lesson possible

None of this means turning a working site into a classroom all day. A more practical ambition is to make learning deliberate within the work that needs doing.

Before a suitable task, agree what the apprentice will attempt and what supervision is needed. Afterwards, ask them to explain the decisions they made. Plan the next step with the training provider, so workplace experience and formal learning reinforce each other. CITB’s apprentice-support guidance describes the role of employer and provider reviews in identifying progress and planning what comes next. CITB, apprentice support.

There is no universal number of minutes that makes this work. The trade, task, experience and risks differ. What matters is whether the person teaching has a realistic opportunity to teach, and whether the learner has a meaningful opportunity to practise.

Nor will good mentoring resolve every barrier. An apprentice who cannot afford the journey, cannot rely on continuing work or cannot access suitable training needs more than encouragement. Those conditions belong in the same conversation.

But construction can make one useful change in emphasis. When celebrating a new intake, ask about the people supporting it. Who are they? What help will they get? What has changed in their workload?

Return to the carpenter beside the apprentice. They have spotted the problem before the cut. This is exactly the moment when experience can become someone else’s understanding.

Has the job been organised so they can use it?
