As a landlord you are legally required to hold a Gas Safety Certificate (CP12) for every rental property with gas appliances, renewed every 12 months. Gas First carries out CP12 inspections for landlords and letting agents across East London — Bow, Stratford, Canary Wharf, East Ham, Dagenham, Barking, Romford, Rainham, Hornchurch, Elm Park, Upminster and Ilford — from our Bow and Dagenham bases. From £69, we inspect your gas appliances, flues and pipework, email your certificate on completion, and can set up annual reminders so you never fall out of compliance.

What a CP12

What a CP12 inspection covers

A Landlord Gas Safety Certificate (CP12) is an annual safety check of the gas appliances, fittings and flues you provide in a rental property. Our Gas Safe registered engineer checks that each gas appliance is burning correctly and safely, tests the gas tightness of the installation, checks that flues and ventilation are clear and working, confirms the safety devices operate, and inspects the pipework and gas pressure. On completion we record the results and issue your CP12 — emailed to you the same day — listing each appliance and its safety status. Inspections start from £69, covering for example a property with a boiler and a hob, with additional gas appliances priced individually depending on the appliance.

Your legal duties

Your legal duties as a landlord

The law places responsibility for gas safety in a rented property on the landlord. You must have a gas safety check carried out every 12 months on the appliances you provide; give a copy of the certificate to your existing tenants within 28 days of the check, and to new tenants before they move in; and keep copies for at least two years. Failing to meet these duties is a criminal offence and can invalidate your insurance. We make staying compliant simple — we can inspect ahead of your renewal date and set up annual reminders so a certificate never lapses.

Why landlords choose

Why landlords choose Gas First for CP12

We work with landlords, letting agents and property managers across East London, and we make CP12s painless: prompt appointments arranged around tenant availability, your certificate emailed on the day, and renewal reminders set up so you never miss a deadline. We can carry out a boiler service at the same visit to cover both jobs in one appointment, and for portfolios we arrange scheduled visits to keep every certificate in order. Because we also repair, if an appliance fails the inspection we can usually put it right and re-issue the certificate quickly — see what happens if a CP12 fails.

A recent CP12

A recent CP12 in Rainham

A landlord in Rainham (RM13) booked a Landlord Gas Safety Certificate for their rental property, which had two gas appliances — a Main Compact 25 combi boiler and a gas hob. We inspected both appliances, carried out a tightness test on the gas meter to confirm there were no leaks on the installation, and checked the flue, ventilation and safety devices. Both appliances were operating safely, so we issued the CP12 and emailed it to the landlord the same day. A straightforward visit — which is exactly how a CP12 should be when a property is well maintained.

Frequently Asked Questions

How much does a CP12 cost?

From £69, covering for example a boiler and a hob. Additional gas appliances are priced individually depending on the appliance, and we confirm the price when you book.

How often do I need a landlord gas safety certificate?

Every 12 months. The gas appliances, flues and pipework you provide must be checked by a Gas Safe registered engineer once a year.

What happens if my property fails the gas safety check?

The engineer classifies the unsafe appliance and, with your permission, makes it safe. Because we also repair, we can usually put the fault right and re-issue the certificate quickly — see our guide on what happens if a CP12 fails.

Do you email the certificate?

Yes — we issue your CP12 and email it to you on the day of the inspection.

How long does a CP12 take?

For a single appliance it usually takes around 30 minutes; a little longer where there are several appliances to check.

Can you do a boiler service and CP12 together?

Yes. We can carry out a boiler service and your CP12 in the same visit to cover both in one appointment.

Do I need a CP12 for my tenant's own appliances?

Your legal duty covers the gas appliances you provide as landlord. A tenant's own appliances are their responsibility, but the pipework, flues and installation you provide are still checked.
