The Complete Guide To Insurance For Gas Engineers
Running a heating & plumbing business always carries some risk — but the right insurance can protect your reputation, income, and peace of mind.
Imagine getting a call from a customer who wants compensation for a leak that you couldn’t have predicted. Perhaps you’re unfortunate enough to become a victim of tool theft, or maybe you’ve had an injury and have to recover for several weeks at home.
Without insurance, any of these scenarios could cost you thousands. With the right cover, it’s just a claim — and you’re back on track.
But what type of insurance do UK gas engineers need? How much coverage? Costs? Here’s all you need to know.
Do Gas Engineers Need Insurance?
Yes — in almost every case.
Some types of insurance are legally required, while others are essential for financial protection and professionalism. At a minimum, gas engineers who employ others must have employers’ liability insurance, but public liability insurance is strongly recommended for everyone working in customers’ homes.
Think of insurance as your safety net. You work hard to keep people’s homes warm and safe — your insurance does the same for your business.
Insurance protects you from:
- Accidental damage to customer property
- Injuries caused during work
- Lost or stolen tools
- Claims from advice or installations gone wrong
- Income loss if you’re unable to work
Having the right policies in place also gives your customers confidence that they’re hiring a professional who takes their trade seriously.
What Types of Insurance Do Gas Engineers Need?
Not every engineer needs every type of insurance, but these are the most common and valuable ones to know about:
1. Public Liability Insurance
Covers injury or property damage claims made by third parties — for example, if a leak damages a customer’s kitchen floor.
Public liability insurance is not legally required, but most customers expect you to have it. Many trade associations and commercial contracts will insist on proof.
Typical cover amount: £2–5 million.
2. Employers’ Liability Insurance
A legal requirement if you employ anyone, even part-time staff or apprentices.
Employers’ liability insurance protects you if an employee gets injured or ill while working for your business.
Minimum cover: £5 million (as required by law).
3. Tools & Equipment Insurance
Your tools are your livelihood. This cover protects them from theft, damage, or loss, whether they’re in your van, at home, or on-site.
Tip: Check if your van policy already includes tool protection — if not, you can add it separately.
4. Professional Indemnity Insurance
Protects you if a customer claims you’ve given bad advice, poor design, or faulty recommendations that caused financial loss.
This is especially useful for engineers who handle system designs, consultancy, or subcontracting.
5. Vehicle & Van Insurance
Standard vehicle insurance might not cover business use or the value of your tools.
Opt for commercial vehicle insurance that includes contents cover and breakdown assistance to keep your operations moving.
6. Personal Accident or Income Protection Insurance
If you’re self-employed, you don’t get sick pay. This type of insurance provides a regular income if you’re unable to work due to injury or illness — helping cover personal bills and rent while you recover.
7. Business Interruption or Office Insurance
Optional, but valuable if you operate from a physical office or workshop. It helps cover lost income if your premises are damaged or temporarily unusable.
QUICK CHECKLIST
If you’re unsure what applies to you, use this as a starting point:
- Sole trader → Public liability + tools cover + income protection
- Small business with staff → Add employers’ liability
- Larger company → Add office/interruption cover and professional indemnity
How Much Coverage Do You Need?
The right level of cover depends on your work type, contract size, and business structure.
General guidance:
- Public liability: £2 million for domestic work, up to £5 million for commercial jobs.
- Employers’ liability: £5 million minimum by law.
- Tools insurance: Value all tools at replacement cost.
- Professional indemnity: At least the total value of your largest project.
Less so for private customers, but many clients, landlords, or local councils will require proof of insurance before hiring you, so make sure your certificates are easy to access and up to date.
How Much Does Gas Engineer Insurance Cost?
Costs vary depending on your level of cover, the size of your business, and your claims history — but here’s a rough guide for UK engineers:
| Type of Insurance | Typical Annual Cost (Sole Trader) | Notes |
| Public Liability | £100–£250 | Basic £2m–£5m cover |
| Employers’ Liability | £150–£400 | Required if you employ staff |
| Tools & Equipment | £50–£150 | Depends on tool value |
| Professional Indemnity | £100–£300 | Optional for consultants/designers |
| Van/Vehicle Cover | £300–£800 | Depends on vehicle type and mileage |
To keep premiums fair, compare quotes and review your policy annually — as your business grows, your cover needs may change.

How to Stay Organised with Your Insurance & Compliance Documents
Insurance is only effective if you can prove you’re covered — and that’s where many engineers slip up.
Keep track of:
- Policy documents and certificates
- Renewal dates and proof of payment
- Employer’s liability certificates (legally required to display)
Rather than juggling paperwork or searching your van for printouts, try to keep digital copies.
