Working at height insurance UK — heights warranties on PL policies, why most claims get declined, and the cover roofers and scaffolders actually need.

Working at height insurance: what UK trades need

If you are a roofer, window cleaner, or scaffolder in the UK, you already know that gravity is your biggest operational risk. What many tradespeople don’t realise until it’s too late is that "working at height" isn’t just a descriptive phrase for your day job—it is a specific, legally binding definition within your insurance policy that can render your cover useless if not handled correctly.

Understanding the dreaded height warranty

In the world of UK commercial insurance, most standard Public Liability policies come with what we call a 'height warranty' or a 'height limit.' Often, a general tradesman policy will cover you up to 5 metres or 10 metres as standard. To a broker, this is a red flag. If you are a roofer working on a three-storey Victorian semi that exceeds 10 metres, and an accident occurs, your insurer has every right to decline the claim because you breached a fundamental condition of the contract.

A warranty isn’t just a suggestion; it is a strict condition. If your policy says "Height Limit: 10m" and you are working at 10.5m, the policy is effectively void for that task. At Premier Insurance, we see too many "cheap" policies bought online where the tradesman didn't spot the 2-metre or 5-metre limit tucked away in the small print. When we review these for our clients, our first job is to ensure that the limit actually matches the reality of their scaffolding or ladder work.

Why most height-related claims get declined

It is a common misconception that if you have Public Liability insurance, you are 'covered for everything.' In reality, the most frequent reason height-related claims are declined in the UK isn't just about the height itself—it’s about the failure to follow the Work at Height Regulations 2005. Insurers expect you to be compliant with Health and Safety Executive (HSE) standards as a baseline for providing cover.

Claims are often rejected because of a failure to provide a written Risk Assessment and Method Statement (RAMS). If a tile falls and hits a parked Mercedes, or worse, a pedestrian, the first thing the loss adjuster will ask for is your risk assessment. If you can’t produce one that specifically addresses the height risks of that job, the insurer may argue you haven't taken 'reasonable precautions' to prevent loss, which is a standard clause in almost every UK policy.

The difference between Public Liability and Employers' Liability

If you have a team, Employers’ Liability (EL) is a legal requirement under the Employers' Liability (Compulsory Insurance) Act 1969. For high-risk trades, this is where the premium starts to climb. While Public Liability covers damage to third-party property or people, EL covers your staff if they fall and suffer a life-altering injury.

Working at height significantly increases the 'burning cost' (the expected cost of claims) for an insurer. A fall from a ladder can lead to a multi-million-pound payout for long-term care. This is why you must be honest about your bona-fide subcontractors (BFSC) and your labour-only subcontractors (LOSC). Failing to declare the correct number of people working at height can lead to a pro-rata reduction in a claim payout—meaning the insurer might only pay 50% of the claim if you only declared half your staff.

What roofers and scaffolders actually need

Specialist trades require specialist wording. If you are a roofer, you don’t just need a height limit that fits; you also need 'Heat Use' cover if you are using torches or heat guns for felt roofing. Standard policies often exclude the use of heat or have extremely restrictive conditions, such as requiring a fire marshal to stand by with an extinguisher for two hours after the job finishes.

For scaffolders, the risk profile is different. You aren't just worried about falling; you are worried about the structural integrity of the scaffold and the liability of it collapsing. You need a policy that doesn't just look at the height you are working at, but the locations you work in. Are you working at 'high-risk' sites like power stations, airports, or railway sidings? Most standard high-street policies exclude these locations entirely.

What does high-risk cover cost?

Price is always a factor, but in high-risk trades, the cheapest policy is often the most expensive mistake you’ll ever make. To give you a rough idea of the UK market in the current climate:

  • Handyman or Painter: Working up to 5 metres, you might see premiums around £15.00 to £25.00 per month for basic Public Liability.
  • Specialist Roofer: Covering heat use and heights up to 15 metres, a sole trader might expect to pay anywhere from £60.00 to £120.00 per month depending on their claims history.
  • Scaffolding Firm: With a small team and high-limit cover, premiums often start at £250.00+ per month due to the extreme risk of both EL and PL claims.

These figures are illustrative. The actual premium depends on your postcode, your years in business, and your specific safety record. As an FCA-regulated broker, our job is to present your "risk" to the underwriter in the best possible light to drive those monthly costs down without stripping away the essential cover.

Practical tips for staying covered

To ensure your insurance holds up when you need it, we recommend three simple habits. First, always photograph your safety setup before starting a job—this is invaluable evidence if a claim arises. Second, check your policy every time you take on a contract that is taller than your usual work. Third, never assume your 'standard' policy covers 'hot work' unless you see it explicitly written in the schedule.

If you are unsure, speak to a specialist. Since we were established in 1983, we have seen the regulatory landscape change significantly. We are members of the British Insurance Brokers' Association (BIBA), which means we have access to schemes that aren't available on price comparison websites. These schemes are designed specifically for the UK construction industry and understand the nuances of things like the "depth limit" as well as height limits.

Commonly asked questions

Does my insurance cover me on a ladder?

Generally, yes, provided you are using the ladder in accordance with HSE guidelines (three points of contact, secured properly). However, many insurers are now pushing for 'fixed platform' work (scaffolding or cherry pickers) for anything over a certain height. Check your policy for a "Access Equipment" clause.

What happens if I go over my height limit just once?

If an incident occurs while you are exceeding your limit, you are effectively uninsured. If you have a one-off job that is higher than your usual limit, call your broker. We can often get a "one-off project extension" for a small additional premium rather than you having to pay for a higher limit all year round.

Is Public Liability tax-deductible?

Yes. Like most business expenses, your insurance premiums are a legitimate business expense and can be deducted from your income when calculating your tax bill for HMRC.

Every trade is unique, and a "one size fits all" policy rarely fits a business that works at height. At Premier Insurance, we take the time to compare over 200 different insurers to find the specific wording that matches your trade. Whether you are a sole trader or managing a large crew, we focus on the details of the warranties and exclusions so you can focus on the job at hand.
