    Gas and Heating Engineers Insurance

    Gas is the one trade on this site where the worst outcome is not a bill. Get a flue wrong and a family does not wake up. That is why registration is the law here rather than a badge, and why we will not write this trade without seeing yours.

    Gas Changes What The Limit Is For

    It also changes what the limit is for. On most trades the limit is sized against buildings. On gas it is sized against people, and a single carbon monoxide claim involving a household will go through £2m without much difficulty. We do not recommend writing gas engineers at that level.

    The other half of the risk is paperwork. Signing a landlord gas safety record is a professional statement that somebody else relies on to meet their legal duty, and it takes twenty minutes. For engineers doing volume certification, that twenty minutes carries more exposure than the installation work does.

    This cover goes by a lot of names. Gas engineer insurance, gas engineer public liability insurance, public liability insurance for gas engineers and insurance for gas engineers are all the same thing, as are gas fitters insurance and gas fitter insurance. Because registration is what insurers actually underwrite, it is also sold as gas safe insurance, gas safe public liability insurance, gas safe engineer insurance, gas safe liability insurance and public liability insurance for gas safe engineers. If you do wet heating as well, you will see heating engineer insurance, heating engineers insurance, heating engineers public liability insurance and gas and heating engineers insurance.

    Two things this page is not. Refrigeration, ventilation, air conditioning and HVAC engineer insurance are related trades with different exposures and they each have their own page, linked at the bottom. And life insurance for gas engineers is personal protection rather than business cover, which our sister firm CoverLife arranges.

    How Much Is Heating & Gas Engineers Insurance?

    Across the plumbing and heating policies on our book, premiums start at around £395 a year. Turnover, how many people work under your direction, the work you take on, working height and your claims record all move it from there, and a larger firm sits well above it. These are premiums arranged for other firms, not a quote for yours.

    We are a broker, so we take it to several insurers rather than quoting one. Call 02382 000820 for a quote.

    What Heating & Gas Engineers Insurance Covers

    Public Liability Insurance

    Answers claims for injury and for damage to other people's property. On this trade that means carbon monoxide exposure, fire, gas escape, and the water damage that comes with any heating system running through a whole building.

    Employers' Liability Insurance

    A legal requirement as soon as you become an employer, subject to limited exemptions, and included in every package we arrange. Registered engineers, apprentices and anyone self-employed working under your direction all count towards it.

    Professional Indemnity

    The cover for what you certify rather than what you install. If a landlord relies on a record you signed and it turns out the check missed something, that is a claim about your judgement, and public liability has nothing to say about it.

    Tools & Equipment Cover

    Analysers, manometers, power tools and hand tools. An analyser needs calibrating and cannot be replaced the same afternoon, so it is worth insuring at what it costs to buy now rather than what you paid.

    Contract Works Cover

    The installation before it is signed off, plus boilers and cylinders sat on site. Unfitted boilers are stolen often enough that insurers ask where they are kept overnight.

    Why Your Paperwork Is Your Defence

    Carbon monoxide claims are not decided on whether you are a good engineer. They are decided on what you can produce from the visit two years ago. Analyser readings, the commissioning record, what you noted about ventilation and the flue route.

    Engineers who keep that properly are in a completely different position from engineers who remember doing the job. It costs nothing at the time and it is the only thing standing between you and a claim that is argued entirely on the other side's evidence. If you do nothing else after reading this page, sort out where those records go.

    Landlord Certificates Are A Different Kind Of Risk

    A landlord safety record is relied on by the landlord for compliance, filed by the agent, and given to the tenant. If something happens afterwards and the inspection is found wanting, all three look at the signature.

    Because that is reliance on a document rather than damage caused by your hands, public liability does not reach it. Professional indemnity does. Any engineer doing rounds of certification for letting agents should be carrying it, and most are not.

    Working Inside Your Categories

    Cover assumes you are working within what you are registered for. Commercial catering, industrial plant and certain appliance types sit outside a standard domestic registration, and stepping over that line is a regulatory problem and a coverage problem in the same moment.

    If the business is moving into commercial kitchens or heat pumps, tell us before the first job rather than at renewal. Heat pumps in particular bring refrigerant, outdoor units at height and design decisions that a policy written for domestic boilers never had in mind.

    Gas Engineers With Claims Or Enforcement Behind Them

    This is a trade where one incident can make renewal genuinely difficult, and where the standard market response is to stop returning calls. That is not the same as being uninsurable.

    What we need is the full story rather than the summary: what happened, what the investigation concluded, and what changed in how you work afterwards. Underwriters who write gas are used to reading that, and a documented change of procedure carries real weight with them. A gap in cover does not, so do not let one open while you shop around.

    If you are mid-renewal and the numbers have moved sharply, ring 02382 000820 and talk it through before you sign anything.

    How To Choose A Broker As A Gas Or Heating Engineer

    Gas is the trade where the cheapest policy and the adequate policy are furthest apart, because the thing that makes it cheap is the thing that makes it fail. We are an FCA regulated broker and will not tell you we are the best choice. These are the questions that decide it, and they work on any broker including us.

    Did they ask about landlord gas safety records?

    This is the question that separates a broker who knows the trade from one who does not. Signing a record is reliance on a document rather than damage from your physical work, so public liability does not answer it and professional indemnity does. For anyone doing volume certification it is the largest single exposure in the business.

    What limit did they lead with, and why?

    If the answer is £1 million or £2 million without a reason, they have sized it against a building. On gas the limit is sized against a household, and a carbon monoxide claim involving a family passes £2 million without difficulty. £5 million is the floor and £10 million is normal on commercial work.

    Have they checked your registration scope against your work?

    Cover follows your Gas Safe registration. An engineer registered for domestic boilers who takes on commercial catering appliances or unvented cylinders has moved outside it, and that is uninsured as well as an offence. The scope should be checked at quote stage, not discovered at claim stage.

    Is the whole of what you do on the schedule?

    Gas, wet heating, plumbing, unvented cylinders, commercial catering, heat pumps and renewables are different exposures that usually sit in one business. Heat pumps in particular bring refrigerant, height and system sizing, none of which is in the mind of a policy written for boiler servicing.

    What happens if you have had an incident or enforcement contact?

    A broker who says it makes you uninsurable has not tried. Underwriters who write gas will read the detail and a documented change of procedure counts for a great deal. What genuinely damages you is a gap in cover while you shop around, so the advice should be to keep something in force throughout.

    One insurer or several?

    A firm doing domestic gas, some commercial work and the occasional heat pump does not fit one appetite neatly. A broker going to several markets can place the awkward parts rather than quietly leaving them off the schedule.

    Factually, here is what we do against those questions. We ask to see your Gas Safe registration before quoting and check its scope against the work you describe, we raise professional indemnity for landlord gas safety records rather than waiting to be asked, we start at £5 million because the limit is sized against people on this trade, and we ask about heat pumps and renewables before the first installation. We are a broker, so it goes to several insurers rather than one.

    Our figures here are real placements rather than illustrations: 45 plumbing and heating policies on the book, starting at around £395 a year. We also insure the plumbers, electricians and refrigeration engineers who work alongside you, so a claim that crosses between trades is familiar ground.

    What We Need To Quote

    • Last year's turnover, and the domestic against commercial split
    • Your registration and which appliance categories it covers
    • Roughly how much of the work is landlord certification
    • Whether you install and commission or service only
    • Any commercial catering, industrial plant or heat pump work
    • Claims and any enforcement contact in the last five years

    Common questions

    Do I need Gas Safe registration to get insurance?+

    For gas work, yes, and we will not write the trade without seeing it. Gas safe insurance is really just liability cover underwritten on the basis of your registration, which is why the certificate is the first thing asked for rather than the last. The important detail is scope: your registration covers specific appliance categories, and cover follows it. Work outside what you are registered for is both an offence and, in practice, uninsured, so an engineer adding commercial catering appliances or unvented cylinders needs the registration extended before the first job and not after it.

    Is gas engineer public liability insurance a legal requirement?+

    No. Employers' liability is the compulsory one, from your first employee at a £5 million statutory minimum. Public liability insurance for gas engineers is not required by law, but Gas Safe registration is, and in practice you cannot work without liability cover either: letting agents, housing associations, builders and commercial clients all make it a condition and ask for the certificate. Treat £5 million as the floor on this trade for the reason above, because the limit is sized against a household rather than a building.

    How much is gas engineer insurance?+

    Plumbing and heating policies on our book start at around £395 a year. Gas work sits above that, because the consequence of getting it wrong is injury rather than inconvenience, and a larger firm goes well beyond it. Those are premiums we arranged for other firms rather than a quote for yours. Call 02382 000820 and we will price your own.

    Am I liable for a landlord gas safety record I signed?+

    Yes, and it is the exposure most engineers overlook. The record is relied on by the landlord to meet a legal duty, filed by the agent and handed to the tenant. If an incident follows and the inspection is found inadequate, all three look at who signed it. Because that is reliance on a document rather than damage from your physical work, public liability does not respond and professional indemnity does.

    What limit should a gas engineer carry?+

    £5m as a floor, and £10m on commercial work. The reasoning is different from other trades: you are not sizing the limit against a building, you are sizing it against a household. A carbon monoxide claim involving a family will move through £2m without much trouble, which is why contracts on this trade tend to name more.

    Can I get cover after a gas incident or enforcement action?+

    Usually, but it needs handling rather than submitting. Underwriters who write gas will read the detail: what happened, what the investigation found, and what you changed afterwards. A documented change in procedure counts for a great deal. What hurts far more than the incident is a gap in cover while you shop around, so keep something in force and ring us on 02382 000820 before you let anything lapse.

    Do I need different cover for heat pumps?+

    It needs adding rather than assuming. Heat pump work brings refrigerant circuits, outdoor units often installed at height, electrical connection and system sizing decisions, and some of it needs separate certification. None of that is in the mind of a policy written for domestic boiler servicing. If you are taking on renewable heating, tell us before the first installation rather than at renewal.

    What is the cheapest public liability insurance for gas engineers?+

    The honest answer is that the cheapest quote and the right quote are rarely the same on this trade, and it is worth knowing why before you buy on price. The cheapest gas engineer insurance is usually cheap because it is written at £1 million or £2 million, and a carbon monoxide claim involving a household moves through £2 million without much difficulty. It is also often written without professional indemnity, which is the only thing that answers a landlord gas safety record you signed. Our own plumbing and heating book starts at around £395 a year across 45 policies, and the way to genuinely reduce a gas premium is registration scope, claims record and an accurate description of the work, not a smaller limit.

    Who insures gas and heating engineers in the UK?+

    Most trades insurers will quote plumbing and heating, and a narrower set will write gas properly, meaning at a limit that reflects the exposure and with professional indemnity available for certification work. Several are reached through brokers rather than direct. Because availability is not the constraint, what separates placements is wording: the limit, whether professional indemnity is included for landlord gas safety records, how your registration scope is reflected, and whether heat pump and renewable work is declared. Ask to see how certification liability is handled, because that is the exposure most policies written for this trade handle worst.

    Does my policy cover me as a gas fitter if I also do plumbing?+

    It should, and it needs declaring rather than assuming. Most engineers on this trade do wet plumbing, heating and gas in the same week, and the mistake is letting one trade description stand in for all of it. Gas fitters insurance and plumbers insurance are usually the same policy with both activities listed, which matters because the water claims are the frequent ones and the gas claims are the severe ones. A schedule describing only one of them is the kind of gap that gets argued when a claim arrives.
