How to get a gas safety certificate
Getting a gas safety certificate takes one visit. This is the process, what to have ready and what it costs with Heating People in East and North London.

Step by step
- Use a Gas Safe registered engineer. Only they can legally check gas appliances for a safety record. Ask to see their Gas Safe ID card.
- List every gas appliance. Boiler, hob, oven, cooker and any other gas appliance the landlord provides, plus the property address and postcode.
- Book and pay. We review the job, send the price, and your booking is confirmed once payment has been received.
- Give access. Someone needs to be there, or the key arrangements agreed, on the day. A two-hour arrival window can be confirmed on the day.
- Receive the record. A digital record is provided on the day the checks are completed.
What to have ready
- Full address and postcode, including the flat number
- Who is booking: landlord, agent or homeowner
- The list of gas appliances, with makes if known
- Your previous record, if you have one
- Tenant or occupier contact details for access
- Parking or permit details for the engineer
Cost
£92.50 for up to two appliances, plus £22.50 for each additional appliance. Gas fires are charged separately.
Where paid parking is needed it is charged at £10 per hour, and key collection is £15 (or £30 to collect and return). These are confirmed before you pay.
Who it is for
Landlords and letting agents, and homeowners who want a documented check, for example before selling. If you are a landlord, read the landlord guide for tenant copies and deadlines.
