What's included

What we check on a gas safety inspection

A thorough Gas Safe check of every gas appliance, flue and supply in the property.

Every gas appliance

We check each boiler, fire, cooker and water heater the property is responsible for, for safe operation.

Flues and ventilation

We inspect flues and ventilation to confirm combustion gases are removed safely and there's adequate air supply.

Pipework and supply

We check gas tightness and the condition of pipework and the supply, so there are no leaks or faults.

Your CP12 record

We record the results and issue your landlord gas safety record (CP12), ready for your files and tenants.

If anything fails the check, we tell you straight away and quote any remedial work upfront. No surprises, no pressure.

Your questions

Gas safety certificate FAQs

What is a CP12 / gas safety certificate?
A CP12 (Landlord Gas Safety Record) is the document a Gas Safe registered engineer issues after checking that the gas appliances, flues and pipework in a let property are safe. It lists what was inspected, the results and any issues found. As a landlord you give a copy to your tenants and keep one on file.
Is a gas safety check a legal requirement?
Yes. By law, landlords in England, Wales and Scotland must have all gas appliances, flues and pipework they provide checked for safety every year by a Gas Safe registered engineer, and give tenants a copy of the record. We keep you compliant and remind you when it's due.
How long is a gas safety certificate valid?
A landlord gas safety certificate is valid for 12 months. You need a fresh check every year. We can book you in early so there's no gap in cover, and we make it easy to keep multiple properties on track.
How much does a CP12 cost?
We charge a fixed price, agreed before we attend, with no call-out fee and no added ULEZ fees. The exact price depends on how many gas appliances are in the property. If you have several properties, we offer a multi-property discount, so just tell us how many when you call.
Can you do multiple properties or a whole portfolio?
Yes. We work with plenty of landlords, letting agents and property managers. Tell us how many properties you need certifying and we'll schedule them together with one point of contact, one tidy invoice and a discount for multiple properties.
How quickly can you do it?
We offer same-week appointments across North & Inner London, booked around your tenants. If you're up against a deadline, let us know when you call and we'll do our best to fit you in fast.
What happens if something fails the check?
If an appliance or part of the system isn't safe, we tell you straight away and explain what's needed. Any remedial work is quoted upfront at a fixed price, with no pressure-selling, so you can decide what to do with no surprises on the bill.
