How Much to Service a Commercial Gas Appliance

If you run a business with commercial gas appliances — whether that’s a catering kitchen, a care home, a school or an industrial unit — regular servicing is essential. But one of the first questions many business owners ask is: how much does it cost to service a commercial gas appliance in the UK?

Let’s break it down in a clear, no-nonsense way.

Average Cost to Service a Commercial Gas Appliance

On average, a commercial gas appliance service in the UK typically costs between £250 and £650 per appliance. However, the exact price depends on a few factors:

• Type of appliance – Larger or more complex systems (like commercial boilers or multi-burner ovens) usually cost more to service than simpler appliances.
• Your location – Prices in London and the South East tend to be higher than in the North or Midlands.
• Number of appliances – Many engineers offer discounts for multiple appliances serviced in one visit.
• Access and condition – If the appliance is hard to access or hasn’t been serviced in a while, expect a slightly higher bill.

Why Regular Servicing Matters

Commercial gas appliances are subject to stricter rules than domestic ones. Servicing isn’t just about keeping things running smoothly — it’s a legal and safety requirement.

• Health & safety compliance – Regular checks help prevent gas leaks, carbon monoxide risks and fire hazards.
• Insurance validity – Many business insurers require proof of regular gas servicing.
• Energy efficiency – A well-maintained appliance runs better and costs less to operate.
• Avoid costly breakdowns – Spotting small issues early can save thousands in emergency call-outs and repairs.

Do You Need a Gas Safety Certificate?

If your business uses gas appliances, yes — you do. A Commercial Gas Safety Certificate (CP42) is usually issued after a successful service. This is essential for:

• Restaurants
• Schools
• Hotels
• Care homes
• Factories
• And any premises with commercial-grade gas equipment

The certificate must be renewed every 12 months.

Some engineers include the certificate in the servicing price, while others may charge an extra £150–£250.

What’s Included in a Commercial Gas Appliance Service?

A typical service should include:

• Visual inspection for signs of damage or wear
• Testing of gas pressure and flow
• Checking safety devices and ventilation
• Cleaning burners and internal parts
• Flue and emissions check
• Reporting faults and recommendations

Always make sure the engineer is Gas Safe registered and qualified to work on commercial systems — this is different from domestic registration.

The Bottom Line

So, how much to service a commercial gas appliance? You’re usually looking at £250–£650, depending on the appliance and location. It might seem like a lot upfront, but regular servicing saves money, keeps your staff and customers safe, and ensures you stay on the right side of the law.

If you haven’t had your appliances checked in the last year, now’s the time.
