How much a London gas safety certificate costs

A London landlord gas safety certificate from Silver Saints is a fixed price, so there is no hourly meter running and no surprise on the invoice. The certificate is £100 plus VAT and includes the inspection of up to 2 gas appliances. Each additional gas appliance is tested in the same visit for £45 plus VAT, so a typical flat with a boiler and a gas hob is covered by the standard £100 plus VAT, while a house with a boiler, hob and a gas fire would be £145 plus VAT. Appointments are available Monday to Saturday at the same rate, and the engineer typically needs 30 to 60 minutes on site depending on the number of appliances and how accessible the boiler, meter and flue are, because each appliance is checked individually against its own manufacturer data plate rather than waved through.

Booking a gas safety certificate and boiler service together

The most cost-effective time to book a gas safety certificate is alongside a boiler service, because both involve a Gas Safe engineer attending the same appliance, and combining them avoids a second appointment and a second visit. The two are different jobs: the certificate is the annual legal safety inspection recorded on the CP12, while a gas boiler service is the maintenance work that keeps the boiler running efficiently and protects the manufacturer warranty. Silver Saints carries out both in one visit when requested at the time of booking, which is why many London landlords schedule the certificate and the service on the same date each year. If the inspection turns up a fault, the same engineer can also quote for gas boiler repairs rather than leaving you to arrange a separate contractor.

What a Silver Saints gas safety certificate actually checks

A landlord gas safety certificate from Silver Saints is a full inspection of every gas appliance, the connecting pipework, the flue and the ventilation in the property, ending in a written Landlord Gas Safety Record. On each appliance the Gas Safe registered engineer checks gas tightness across the installation, standing and working pressure where test points exist, and burner pressure and gas rate against the manufacturer data plate rather than against a rule of thumb. Ventilation is checked so the appliance has the air supply it was designed for, flue flow is tested to confirm the products of combustion are being carried safely outside, flame failure devices are checked for correct operation, and physical stability and the presence of stability brackets are confirmed. Anything found to be unsafe is recorded and explained, not glossed over.

Gas safety certificates across different London property types

The same certificate is required everywhere, but the work behind it varies sharply by London building stock, which is where an engineer who works the capital daily earns their keep. In Victorian and Edwardian conversions the gas meter, boiler and hob are often spread across three floors with original pipework that has been extended by successive owners, so the tightness test matters more than in a new build. Period properties with a back boiler or an older open-flue appliance need careful flue flow and ventilation checks, since blocked or shared flues are a common reason an appliance fails. Mansion blocks and purpose-built flats frequently have communal or shared flue arrangements that have to be assessed in context. Modern new-build flats, common in Canary Wharf and the regeneration zones, usually have a single room-sealed combi boiler and are the quickest to certify. Knowing which to expect by postcode is why a London-based Gas Safe engineer rarely has to book a wasted second visit.

Where London landlords use this most

Demand for landlord gas safety certificates is heaviest in the high-rental inner boroughs, Camden, Islington, Hackney, Tower Hamlets, Lambeth, Southwark, Wandsworth, Westminster and Kensington and Chelsea, where the rented housing stock is dense and managing agents run annual renewal cycles. Silver Saints covers these alongside the outer boroughs such as Bromley, Croydon, Ealing and Richmond, and the adjacent TW, KT, CR and BR postcodes. Because so much London rental stock is in period conversions and ex-local-authority blocks, the practical difference between engineers is how confidently they handle older flues and shared installations, not whether they can tick a box on a modern combi.

The legal position, in plain terms

Under the Gas Safety (Installation and Use) Regulations 1998, every landlord letting a property with gas appliances must have a Gas Safe registered engineer inspect them every 12 months and must give a copy of the record to existing tenants within 28 days of the check and to new tenants before they move in. The certificate can be renewed up to 2 months before it expires without losing the original expiry date, so there is no penalty for booking early and no reason to let cover lapse. A homeowner who is not letting the property is not legally required to hold one, though many arrange a check for peace of mind, and commercial premises need a separate commercial gas safety certificate rather than the landlord CP12.

The multi-trade advantage on the same visit

Because every Silver Saints engineer is a multi-trade tradesperson as well as Gas Safe registered, a single visit can cover more than the certificate alone, with no second call-out. Landlords preparing a property between tenancies commonly combine the gas safety certificate with a boiler service, a radiator valve repair, draught proofing, or small fixing and fitting jobs flagged at the same inspection, all booked under one appointment rather than waiting on separate trades.

What happens if an appliance fails the gas safety check in London?

If an appliance is found to be unsafe during the inspection, the Silver Saints engineer records the fault on the certificate and explains it, and because every engineer is multi-trade and Gas Safe registered, many faults can be discussed and arranged for repair rather than leaving you to find a separate contractor.
