How to Check a Tradesperson Is Insured

A smart-looking quote and a friendly manner can be reassuring, but they do not tell you what happens if something goes wrong. If you want to know how to check a tradesperson is insured, the answer is not simply to ask, “Are you insured?” It means checking what cover they hold, whether it is current, and whether it suits the type of work you are hiring them to do.

Insurance is one of the clearest signs that a business takes its responsibilities seriously. It will not guarantee perfect workmanship, and it does not replace proper vetting, references or a written agreement, but it does show that the tradesperson is operating with a level of professionalism and accountability that every customer should expect.

Why insurance matters before work begins

When a tradesperson works on your home or business premises, there is always some degree of risk. A ladder could damage a parked car, a pipe could be fitted incorrectly and cause a leak, or a visitor could trip over tools left in a hallway. Even highly skilled professionals can face accidents, unexpected damage or claims.

That is where insurance matters. The right policy can help cover injury, property damage or mistakes, depending on the type of insurance in place. Without it, you may find yourself dealing with delays, disputes and costs that are much harder to resolve.

It is also worth remembering that not every trade carries the same level of risk. Someone assembling fitted furniture in a spare room does not present the same exposure as a roofer, electrician or builder carrying out structural alterations. That is why the detail matters.

How to check a tradesperson is insured properly

The most reliable approach is to ask for evidence, not reassurance. A professional tradesperson should be comfortable providing proof of insurance before work starts, especially for larger jobs.

Ask for an insurance certificate

Start by asking to see their insurance certificate or schedule. This should normally show the insurer’s name, the policy number, the type of cover and the period of insurance. Check that the policy is current and that the business name matches the name on the quote, invoice or company paperwork.

If the paperwork is in a different name, ask why. There may be a straightforward explanation, such as trading under a business name while the policy is held by a limited company, but it should be clear and consistent.

Check the dates carefully

A surprisingly common mistake is to glance at a certificate and assume everything is fine. Look at the start and end dates. If the policy expires next week and the work runs for two months, you are entitled to ask whether it will be renewed and whether cover will remain in place throughout the project.

For longer jobs, especially extensions, refurbishments or specialist installations, this is more than a box-ticking exercise. Cover needs to remain active for the duration of the works.

Look at the type of insurance, not just the existence of it

A tradesperson can be insured, but not necessarily insured for the right things. Public liability insurance is one of the most commonly requested policies. It can help cover claims if the contractor causes injury to another person or damage to property.

That said, public liability insurance does not usually cover poor workmanship by itself. For design, advice or specification errors, a business may need professional indemnity insurance. If they employ staff, they will generally need employers’ liability insurance too.

For domestic customers, public liability is often the first thing to check, but it should not be the last thing you ask about.

Make sure the cover reflects the work involved

A decorator working indoors on a small room may have very different insurance needs from a tree surgeon, gas engineer or loft conversion specialist. Ask whether their policy covers the type of work they will be carrying out at your property.

This is particularly important for higher-risk activities such as roofing, scaffolding, hot works, groundwork, drain work or structural alterations. Some policies exclude certain tasks, heights or tools. A business may be insured in general terms but excluded from the exact work you need done.

Check the level of cover

Insurance certificates often show the indemnity limit, such as £1 million, £2 million or £5 million. There is no single figure that suits every project. For minor domestic jobs, lower levels may be common, but for more substantial work or commercial premises, higher cover may be more appropriate.

If a contractor seems unsure about their level of cover, that is worth noticing. A professional business should understand the basics of its own insurance arrangements.

Which insurance policies are most relevant?

Public liability insurance

This is usually the first policy customers ask about. It can cover accidental injury or accidental damage caused to third parties or their property during the course of the work.

If a plumber causes a leak that damages flooring, or a builder drops materials and cracks a neighbour’s windscreen, public liability may be relevant. It is a key form of protection, but it is not a catch-all policy.

Employers’ liability insurance

If the tradesperson has employees, this is generally a legal requirement in the UK. It covers claims from employees who are injured or become ill through their work.

This may not sound directly relevant to a customer, but it tells you something about whether the business is operating properly. If a firm has a team on site, it should be able to show this cover.

Professional indemnity insurance

This is more common where design, advice or specifications are part of the service. Architects, surveyors, specialist designers and some building professionals may hold it.

If you are relying on a tradesperson’s technical recommendations rather than simply asking them to carry out a straightforward task, this can be worth checking.

Contract works or tools cover

These policies are not always essential for the customer to verify, but they can still be useful to ask about on larger projects. Contract works insurance may cover works in progress, while tools cover protects the contractor’s own equipment.

These do not replace public liability, but they can indicate a more fully organised business.

Red flags to watch for

A genuine professional should not become defensive when asked for insurance details. If someone avoids the question, says their paperwork is unavailable, or insists insurance is unnecessary because they have “never had a problem before”, take that seriously.

Another warning sign is vague wording. If a tradesperson says they are “covered for everything”, ask them to be specific. Insurance rarely works that way. Clear answers matter more than confident ones.

Be cautious, too, if the price seems unrealistically low and the business has no paperwork, no company address and no evidence of insurance or references. Cost savings can disappear quickly if a problem arises.

Insurance is important, but it is not enough on its own

Knowing how to check a tradesperson is insured is useful, but it should sit alongside a few other checks. Insurance tells you something about risk management. It does not tell you whether the work will be carried out to a high standard, whether communication will be good, or whether the business has a reliable track record.

That is why sensible customers also look for signs of proper vetting, established trading history, clear quotations, customer feedback and professional standards. A tradesperson who belongs to a respected trade association and has already undergone checks on insurance, business credentials and customer references can offer a stronger level of reassurance than someone listed on an open marketplace with little oversight.

In practice, the best approach is to look at the whole picture. Insurance, written terms, references, accreditation and professionalism all matter. If one part is missing, ask why.

When you might need to ask more questions

Some jobs call for a little more scrutiny. If the works involve listed buildings, specialist heritage materials, structural changes or expensive finishes, it is reasonable to ask detailed questions about both insurance and experience. The same applies if access is difficult, if neighbouring properties could be affected, or if the project will involve multiple subcontractors.

Subcontracting is a point many customers overlook. If the person quoting for the job brings in others to carry out part of the work, ask who is insured and for what. It should be clear whether those workers are covered under the main contractor’s policy or need their own.

This is also sensible for projects in occupied homes, where there is more potential for accidental damage, disruption and safety concerns.

A simple way to protect yourself

Before agreeing to any work, ask for proof of insurance in writing, read it carefully and make sure it fits the job you are planning. If anything is unclear, ask for clarification before work starts, not after an incident.

Professional tradespeople understand why customers ask these questions. In many cases, they welcome them, because careful clients tend to value good workmanship and proper standards. That makes for a better working relationship from the outset.

Choosing someone on price alone can be a false economy. Choosing someone who is transparent, properly insured and accountable gives you a firmer footing if plans change or problems arise – and far more confidence when the work begins.
