If you have been working in the London or Essex construction sector for any length of time, you already know that the cladding crisis isn’t just a "safety issue", it is a full-blown financial one. But the latest data from the July 2026 government Remediation Programme Insurance Survey has finally put a hard number on the problem, and it is a staggering 56%.
According to the findings, buildings with unsafe or flammable cladding now cost roughly 56% more to insure than those without such defects. For property owners, this is a nightmare. For you, the contractor, it’s a direct threat to your bottom line, your General Contractor Liability Insurance, and your ability to secure new work.
I’ve been speaking with brokers across the industry recently, and the sentiment is clear: the insurance market for anything involving external wall systems (EWS) remains incredibly "hard." Even as remediation work progresses, the costs aren't coming down as fast as we’d all like. In fact, many firms are finding that their premiums stay stubbornly high even after the scaffolding has been taken down.
The 56% Premium Gap: Breaking Down the Numbers
The July 2026 survey, which looked at over 2,000 buildings across England and Wales, revealed that buildings with flammable cladding faced an average premium rate of 0.14% of the sum insured. Compare that to buildings that were either defect-free or already remediated, which sat at 0.09%.
While a 0.05% difference might look small on paper, when you apply it to a £15 million London residential block, the numbers become massive. We are talking about average total premiums of £20,000 per building, with some units facing costs of over £1,800 a year just for insurance.
For contractors working in the Business Insurance London or Business Insurance Essex markets, these figures are critical. When a client sees their insurance costs ballooning, they look for someone to blame, and often, they look toward the professionals who handled the original installation or the ones currently tasked with the fix.
Why Premiums Stay High After the Work is Done
I often hear contractors ask: "If we’ve fixed the cladding, why is our liability insurance still through the roof?" It’s a fair question, but the answer lies in how insurers view risk, and it’s more complex than just "replacing the panels."
- The "Claims-Made" Reality: Most professional indemnity and liability policies for contractors work on a "claims-made" basis. This means the insurance in place now has to cover work you did years ago. Insurers are still terrified of the "long-tail" risk of historic projects coming back to haunt them, even if your current work is 100% compliant.
- Property Risk vs. Life Safety: Current standards like PAS 9980 focus on "life safety", getting people out of the building alive. However, insurers care about "property risk", preventing the building from burning down entirely. Even if a building is "safe enough" for residents, an insurer might still see it as a total loss risk, keeping the premium high.
- Legal Extensions: Recent legal changes, including the extension of limitation periods under the Defective Premises Act, mean contractors are now liable for work done up to 30 years ago. That is a massive window for claims, and insurers price that uncertainty into your Construction Contractor Insurance.
The Impact on Essex and London Contractors
In London and the surrounding Essex areas, the concentration of high-rise buildings and complex developments is higher than anywhere else in the UK. This puts a unique pressure on local firms.
If you are a contractor based in Chelmsford or Romford but working on high-rise projects in the City or Canary Wharf, you are likely finding that many standard insurers won't even look at your business if you have any exposure to "cladding remediation." The market has shrunk, and those who are left are charging a premium for the privilege of coverage.
In fact, some government-funded remediation projects now require contractors to carry Professional Indemnity (PI) limits of up to £10 million. In my experience, very few small-to-medium-sized firms can easily find, or afford, that level of cover without a specialized broker. This creates a barrier to entry, where only the biggest players can compete for the work, despite the desperate need for more contractors to solve the cladding backlog.
Practical Steps: How to Fight Back Against Rising Costs
While you can’t control the global insurance market, you can control how you present your business to an underwriter. Here is what I recommend for any contractor currently struggling with their General Contractor Liability Insurance:
- Document Everything: When applying for renewal, don’t just send a one-page form. Provide a detailed "risk profile" that includes your specific remediation methods, the materials you use (A1 or A2 rated only), and your quality control processes.
- Showcase Your Expertise: If you have specific certifications or have completed PAS 9980 training, highlight it. Insurers are looking for reasons to say "yes," and proving you are a specialist rather than a generalist can help.
- Start Early: Do not wait until 30 days before your renewal. In the current climate, you need at least 60 to 90 days to shop the market, especially if you need high limits for London-based projects.
- Work with a Specialist Broker: A generalist broker might not understand the nuances of the cladding market. You need someone who speaks the language of underwriters and can argue your case based on the specific safety measures you’ve implemented.
Looking Ahead: Is There Light at the End of the Tunnel?
The government survey has triggered a "focused review" by the Financial Conduct Authority (FCA). They are looking into whether insurers are providing "fair value" to leaseholders and how remediation work is being reflected in pricing.
I think we will see some stabilization toward the end of 2026, but it won't be a quick drop. The industry is still licking its wounds from the post-Grenfell fallout. Going forward, the contractors who will thrive are those who embrace transparency and treat their insurance renewal as a critical part of their business strategy, rather than just an administrative chore.

Frequently Asked Questions
1. Why did the government survey find a 56% increase in cladding-related insurance?
The July 2026 survey found that buildings with unsafe cladding have a higher "premium rate" (0.14%) compared to those without (0.09%). This reflects the higher risk of fire spread and property damage perceived by insurers.
2. Does removing cladding immediately lower my liability insurance premiums?
Not necessarily. Because of "claims-made" policy structures, you remain liable for past work. However, over time, a clean record of remediated projects will make your business more attractive to underwriters and should lead to more competitive rates.
3. What is the difference between PI and General Contractor Liability Insurance for cladding?
Professional Indemnity (PI) covers you for errors in design or advice, which is where most cladding claims fall. General Liability usually covers physical damage or injury on-site. Both are becoming harder to secure for contractors involved in EWS work.
4. How can Essex-based contractors find better rates for London projects?
By working with a specialist broker who can differentiate your risk from the "broad-brush" exclusions often applied to the construction sector. Detailed documentation of your safety protocols is essential.
