Building Safety Levy 2026: 3 Likely Implications for UK Contractors
The Building Safety levy has come into full effect. This new charge on residential development aims to address historic building safety issues. It arrives at a time when the industry is already under strain. HBF reports that just 208,000 new homes were completed in 2024/25, down 16% from the 2020 peak. Here’s what the levy is expected to change:
- HBF’s Viability Crunch Report (May 2026) estimates the levy will add to the cost of building a new home.
- Unlike larger developers, SME builders will pay the levy when the first home on site completes, a stage when cash often runs tight.
- The UK Government ruled out an exemption for medium-sized sites. This means the levy will incur costs to smaller developers too.
The levy may not affect you directly, but when your clients’ costs increase, that pressure is likely going to be felt further down along the supply chain. In this article we explore three ways the levy is most likely to affect contractors, what some of the recent industry cases tell us, and four simple checks to help you make sure your cover is right for the months ahead.
3 Implications the Building Safety Levy is Likely to Have on Contractors
1. Heightened costs could make developments financially unviable
A recent survey carried out by Home Builders Federation (HBF) and Quantum Development Finance, shows that 91% of the SME home builders across England believe the levy will have a major cost implication on developments making them financially unviable.
36% of those surveyed said they’ve already delayed, redesigned or cancelled schemes in anticipation of the levy.
The cost is significant. HBF’s Viability Crunch report, found that around £76,000 has been added to the cost of building a typical new home since 2020, and the levy accounts for £2,320 of that. The timing adds to the strain. SME builders, unlike larger developers, must pay the levy when the first home on a site is completed. That’s one of the most cash-constrained points in a build.
HBF Chief Executive Neil Jefferson warned that the levy “will make even more developments unviable”. These changes have a direct impact on contractors.
Fewer viable sites mean fewer packages to tender for, tighter margins, and clients under heightened cash flow pressure.
Where the pressure is sharpest:
The survey found that 69% of SME builders say the levy makes them less likely to invest in new development. The figure is highest in London at 86.7%.
2. Added cost pressure could push more main contractors under
With the levy adding cost at first completion, contractors already carrying heavy liabilities will have even less room to absorb a shock. In June 2026, Ardmore Construction Group went into administration owing creditors £29m. Ardmore shows what happens to the supply chain when a main contractor runs out of road.
Administrators say the group still faces 23 potential developer claims, with total exposure of up to £300m.
The subcontractors didn’t cause those defects, yet they’re still paying the price.
There’s a practical lesson here too. The losses were smaller than many feared because firms tightened credit as worries grew about Ardmore’s building safety exposure.
3. When firms fail, directors are likely to face closer scrutiny
If rising costs push more firms into insolvency, the scrutiny won’t stop at the company itself.
On 21 August 2026, Construction News reported that the two directors of collapsed cladding firm M Price Group were asked to repay more than £600,000.
The insolvency specialist handling the case said they had failed to explain various transactions made before the collapse. The firm went into administration in August 2024. The group struggled to repay an emergency Covid loan and was then hit by a £7.8m adjudication in a dispute with Barratt Homes.
A separate case shows how large legacy claims can become. Administrators of Sto Ltd received £135.15m in unsecured claims.
Taken together, these cases show a clear pattern.
When a firm fails under the weight of building safety claims, liquidators and claimants look closely at where the money went and who made the decisions.
Actions You Can Take Immediately
Although the levy is already in full effect from today, there’s still time to take action to ensure your business is prepared. You can’t control rising costs or what happens to the contractors above you.
You can make sure your cover is up to date and that you know exactly where you stand if something goes wrong. Here are four practical checks to make right now.
- Review your sums insured: build costs have risen sharply. Check that your contract works and plant values reflect today’s prices, not last year’s.
- Vet your principal contractor: look at their latest accounts, their payment track record and any exposure to building safety claims. As the Ardmore case shows, early caution protects your balance sheet.
- Know where you stand if a contractor above you collapses: ask your broker a few specific questions. Whose Contractors All Risks (CAR) policy covers your works? What happens to that cover if the main contractor fails mid-project? Does your public liability cover stand on its own? Also check your payment terms and retentions, because standard CAR and liability policies aren’t designed to pay unpaid invoices.
- Check your directors’ protection: if you run a limited company, it’s worth reviewing whether directors’ and officers’ cover is in place.
