Gas Safety Certificate Cost in UK
If you are a landlord or a homeowner, knowing the cost of a Gas Safety Certificate (CP12) is vital for your annual budget. In 2026, prices can fluctuate based on where you live and how many gas items you own.
At Gas Certificate, we believe in total transparency. We have built our reputation as the most affordable and professional provider in the country, ensuring you never pay more than you should for your legal compliance.
Average Gas Safety Certificate Prices:
What to Expect
On average, a standard Gas Safety Certificate in the UK costs between £60 and £90 for a single appliance (usually the boiler). However, at gascertificate.co.uk, we leverage our large network of local engineers to keep these prices lower for our customers.
Why Prices Vary: The London Factor vs. National Rates
It is no secret that London is often more expensive due to parking fees and the ULEZ/Congestion Charge. While some companies charge upwards of £120 in the city, we are proud to be the most affordable gas certificate provider in London. By using local engineers who live in the areas they serve, we cut down on travel costs and pass those savings directly to you.
Key Factors That Influence Your CP12 Quote
Number of Appliances: Most engineers charge a small extra fee for every additional gas item they need to test.
Property Location: Remote areas or high-traffic city centres can impact the call-out fee.
Speed of Service: Need a certificate today? Many firms charge a huge premium for last-minute bookings, but our same-day service remains one of the most competitive in the UK.

Should You Bundle Your CP12 with Other Services?

- Boiler Service: Keeps your system running efficiently and prevents breaks.
