Construction Industry Labour Shortage in the UK: Causes and Solutions

The construction labour shortage is not a short-term blip. It is a structural gap between the workers the industry needs and the workers available to site.

This guide explains how big the shortage is, what is causing it and how a construction staffing agency and better planning can help contractors keep sites staffed.

The Construction Industry Training Board (CITB) forecasts that UK construction needs about 41,200 extra workers a year between 2026 and 2030, or roughly 206,000 in total.

At Bureaulogic, a specialist construction staffing agency with offices in Essex and Kent, we supply site labour and trades across London, Essex and Kent, so the practical side of this shortage is something we see in every brief.

How Big Is the Construction Labour Shortage in the UK?

CITB's Construction Workforce Outlook 2026 to 2030 estimates that UK construction must recruit about 206,000 additional workers over five years, or around 41,200 a year. That is equal to 1.6% of the 2025 workforce each year, as reported by ACE after the report's publication in June 2026.

This is a recruitment requirement, not a net increase in headcount. CITB projects the workforce growing from about 2.61 million in 2025 to roughly 2.68 million by 2030.

Output is forecast to dip by 0.2% in 2026, then grow in each following year, led by infrastructure, public new housing and private new housing.

So demand for labour is expected to rise while the pool of available workers stays under pressure.

What Causes the Construction Labour Shortage?

The shortage comes from several pressures at once: an ageing workforce, too few young entrants, a smaller self-employed and migrant labour pool, and demand that keeps growing. No single cause explains it. Much of the most detailed evidence comes from CITB's own submission to a parliamentary inquiry, so the figures below are labelled with their year.

• An ageing workforce. In its 2022 written evidence to Parliament, CITB said nearly a quarter of the workforce was aged 55 or over, compared with just over 10% in the early 1990s.

• Fewer young entrants. The same evidence says the share of workers aged 16 to 24 fell from 22% to 10% over that period, and the average age of the workforce rose from 39 to 42.

• Early exits. A 2019 CITB survey found nearly half of employers felt workers leave early because of the physical nature of the work, ill health or injury.

• A smaller self-employed pool. CITB reported that self-employment fell 14% between 2019 and 2021, and it makes up over 35% of the workforce.

• Fewer migrant workers. CITB reported that migrant workers in construction fell 8% during 2020.

• Weaker training pipelines. In 2020/21, apprenticeship starts in England were 10% lower than in 2018/19, according to the same evidence.

• Growing demand. Infrastructure, housing and retrofit programmes need more people at the same time as experienced workers retire.

These are older figures, and the picture may have shifted since, but the direction of travel matches CITB's latest forecast.

What Does the Labour Shortage Mean for Contractors?

For contractors, a labour shortage means more competition for the same workers, which makes late hiring riskier and programmes harder to protect. The workers you need on a Monday morning are often already committed elsewhere.

• Roles take longer to fill when you brief late.

• Workers with the right cards and experience have more choice of site.

• Last-minute cover is harder to find, so a single no-show can hold up a gang.

• Pressure to compromise on checks to fill a gap creates compliance risk.

None of this is new, but the forecast suggests it will not ease quickly.

How Can Contractors Cope With the Labour Shortage?

The most effective response is to plan labour earlier, tell your recruitment partner what is coming and make your sites easy to say yes to. A shortage rewards contractors who are organised, reliable and clear about what they need.

1. Plan labour at programme stage. Map the roles, numbers and start dates for each phase, then share that forecast with your agency as early as you can.

2. Mix your labour model. Use temporary cover for peaks, contract workers for fixed-length packages and permanent hires for the roles you cannot afford to lose.

3. Build compliance into mobilisation. Confirm the cards, tickets and inductions each role needs before the worker is booked, not after they arrive.

4. Make your site attractive. Clear start dates, realistic durations, prompt payment and good welfare facilities all help you keep good workers.

5. Invest in training. CITB reported that its grants supported over 7,000 employers to employ over 18,000 apprentices between April and December 2021, so funding is worth checking.

6. Use a specialist construction staffing agency with local reach. An agency with a local candidate bank can reach workers who can realistically get to your site.

How Can a Construction Staffing Agency Help With the Labour Shortage?

A construction staffing agency cannot create workers the industry does not have, but it can give you earlier access to the available pool. It finds, checks and supplies labour and trades on a temporary, contract or permanent basis, which shortens the time between briefing and a worker arriving on site.

• Temporary cover for urgent, short-term and project-based requirements.

• Contract workers for packages with changing staffing needs.

• Permanent recruitment for long-term site and management positions.

• Checks on experience, availability, references and required documentation before placement.

• Coverage across site and groundworks, the trades, supervision and civil engineering and highways. You can see the full range on our construction and civil engineering staffing page.

The earlier you share your forecast, the more choice an agency has when it matches workers to your roles.

Mistakes to Avoid During a Labour Shortage

When labour is tight, the temptation is to move fast and accept whoever is available. That usually costs more later.

• Waiting until the week before a start date to brief your agency.

• Skipping card, right-to-work and reference checks to fill a gap.

• Competing on rate alone and ignoring site conditions, payment terms and duration. • Relying on a single supplier or a handful of individuals with no backup.

• Treating the shortage as temporary and putting off training and succession planning. • Choosing a construction staffing agency with national reach but no local candidates near your site. Avoiding these keeps your programme protected when supply is tight.

Frequently Asked Questions

Is there a labour shortage in UK construction?

Yes. CITB's Construction Workforce Outlook 2026 to 2030 estimates the industry needs about 41,200 extra workers a year, or around 206,000 over five years, as reported in June 2026.

What is causing the construction labour shortage?

The main causes are an ageing workforce, fewer young people entering the industry, a fall in self-employed and migrant workers, and growing demand for infrastructure and housing.

Will the construction labour shortage get worse?

CITB expects output to dip in 2026 and then grow each year to 2030, which keeps pressure on recruitment. Contractors should plan for continued competition for skilled workers.

Can a construction staffing agency solve the labour shortage?

No agency can create new workers, but a specialist construction staffing agency can give you earlier access to available, checked candidates. Briefing early and clearly improves your chances of filling roles on time.

How early should I brief my agency?

As early as you know the roles, numbers and start dates. Even a rough forecast helps, and urgent requests can still be discussed with our consultants Monday to Friday, 8am to 6pm, or on call for emergencies.

Plan Your Labour Before the Programme Starts

Instead of asking where the next worker will come from, ask how early you can tell your agency what you will need.

Write down your next three months of roles, numbers and start dates, and send them to a specialist construction staffing agency that covers your area.

To start that conversation, contact the Bureaulogic team.
