Gas safety certificates across South London — for landlords and homeowners

Landlords in England are legally required to have a gas safety inspection carried out by a Gas Safe registered engineer every 12 months and to provide tenants with a copy of the certificate within 28 days of renewal. R.W. Miller issues gas safety certificates (CP12) for residential properties across South London, covering SW and SE postcodes in Wandsworth, Lambeth, Southwark, Lewisham, Greenwich, and Bromley.

Reion is Gas Safe registered (number 919881), which means he is legally authorised to carry out gas safety inspections. Each inspection covers all gas appliances in the property — boiler, cooker, gas fires, and any other gas-powered equipment — as well as pipework and flue integrity. The certificate is issued on the day of inspection.

Failing to hold a valid gas safety certificate as a landlord is a criminal offence. If you are a homeowner buying or selling a property, or simply want confirmation that your gas appliances are safe, a homeowner gas safety check provides the same reassurance. Call 07375 813996 to book.

Who needs a gas safety certificate

Landlords All landlords of residential properties with gas appliances must hold a valid annual gas safety certificate or risk prosecution and an unlimited fine.
Landlords renewing tenancies A new certificate must be issued within 12 months of the previous one — tenants must be provided with a copy before or at the start of each new tenancy.
Homeowners selling a property While not legally required, a gas safety certificate provides buyers with independent confirmation that all gas appliances are safe and correctly installed.
Homeowners with aging gas appliances If your boiler, cooker, or gas fire is over 10 years old and has not been recently inspected, a safety check provides peace of mind and can identify any risks early.
HMO owners Houses in Multiple Occupation have additional compliance requirements — all gas appliances must be certificated and records kept for a minimum of two years.

Frequently asked questions

How much does a gas safety certificate cost in South London?
R.W. Miller charges a fixed fee for a standard gas safety certificate inspection in South London. The price covers the visit, inspection of all gas appliances, and the certificate issued on the day. Call 07375 813996 for the current rate — there are no additional charges unless remedial work is required.
How often do landlords need a gas safety certificate?
Landlords must renew their gas safety certificate every 12 months. The inspection must be carried out by a Gas Safe registered engineer, and a copy of the certificate must be given to all existing tenants within 28 days of renewal and to new tenants before they move in.
What happens if I am a landlord without a valid gas safety certificate?
Letting a property without a valid gas safety certificate is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. Landlords can face unlimited fines and up to six months' imprisonment. Beyond the legal risk, an un-inspected property puts tenants at risk of carbon monoxide poisoning and gas leaks.
Do homeowners need a gas safety certificate?
Homeowners are not legally required to have a gas safety certificate, but it is strongly recommended — particularly for older properties or if appliances have not been recently inspected. A homeowner gas safety check from R.W. Miller gives you independent confirmation that your boiler, cooker, and any gas fires are safe and burning correctly.
How long does a gas safety inspection take?
A standard gas safety inspection for a typical South London property with a boiler, cooker, and one or two other appliances takes between 30 and 60 minutes. Properties with more gas appliances or older pipework may take longer. The certificate is issued the same day.
