Licensing and accreditation for plumbers
Plumbers are not required by law to hold a formal licence, but most work on domestic gas installations, heating systems, and water systems must be carried out by Gas Safe registered engineers (for gas work), OFTEC registered technicians (for oil systems), or competent persons following Building Regulations. The Building Regulations framework (Part G for water systems, Part L for heating) applies to all plumbing installations in homes.
Clients routinely request proof of appropriate registration before allowing any work on heating or water systems. Gas work in particular is illegal if not carried out by a Gas Safe registered engineer. Many mortgage providers and insurers of the property require this certification.
Public liability insurance is not a legal requirement but is almost universally required by homeowners and commercial clients as proof you can cover damage claims. Most insurance policies are underwritten on the basis that you hold appropriate registration (Gas Safe, OFTEC, or Building Regulations compliance).
Insurance works alongside registration by protecting you financially from claims. If you are Gas Safe registered or OFTEC certified, your insurer will recognise that you meet industry safety standards, and cover claims arising from work carried out within those schemes.
How much does plumbers insurance cost?
£180 – £450 per year for sole traders; plumbers with employees or those specialising in high-value heating systems may pay £500 – £950

Common questions about plumbers insurance
Do I need public liability insurance as a plumber?
Public liability insurance is not legally required for self-employed plumbers, but most domestic and commercial clients expect you to have it. Many trade bodies also require a minimum level of cover as a condition of membership.
What level of public liability cover do plumbers need?
Most plumbers choose between £1m and £5m of public liability cover. If you work on commercial projects, clients often require at least £2m or £5m as a contract condition.
Does plumbers insurance cover water damage to a customer's property?
Yes, public liability insurance covers accidental damage to third-party property caused by your work. If a pipe you fitted leaks and damages a customer's floor, your policy would cover the claim, subject to the terms and excess.
Do plumbers need professional indemnity insurance?
If you design heating systems, specify materials, or advise clients on the best solution, professional indemnity protects you if that advice leads to a financial loss. It is especially relevant for plumbers who produce technical drawings.
Is employers liability insurance compulsory for plumbers?
If you employ anyone, including apprentices, you are legally required to have employers liability insurance with a minimum of £5m cover. Sole traders with no employees are exempt.
Do I need Gas Safe registration to work on boilers and heating systems?
Any work on gas installations, including boiler repairs and servicing, must be carried out by a Gas Safe registered engineer in the UK. It is a legal requirement and your insurance will require you to hold current registration. Working on gas without Gas Safe registration is illegal and will invalidate your insurance.
What is the difference between Gas Safe, OFTEC, and Building Regulations compliance?
Gas Safe covers gas installations; OFTEC covers oil heating systems; Building Regulations cover water and heating system design in homes. You may need multiple registrations depending on the type of work. Your insurance policy will specify which registrations are required for different activities.
Am I covered if I unblock drains or carry out maintenance on someone else's systems?
Yes, drain unblocking and maintenance work on existing systems are typically covered. However, some policies may exclude certain high-risk activities such as high-pressure jetting in commercial sewer systems. Confirm your specific activities are included before quoting.
Does public liability cover water damage caused by my work?
Yes, public liability covers claims if your installation or repair work causes water damage to the customer's property or neighbouring properties. This is one of the most common claims in plumbing, so make sure your policy limit is adequate for the properties you work on.
What should I do if I install a system that develops a fault years later?
Professional indemnity insurance can cover claims made years after the work, provided the claim is notified during the policy period. Discuss the length of cover offered and any 'tail' provisions with your insurer, especially if clients rely on long-term system guarantees.
