Gas Safety Certificate (CP12) Hillingdon

We cover every Hillingdon postcode in UB3–10 with same-day bookings if you ring before 11am, and next-day bookings as standard. Typical arrival window is a one-hour slot, confirmed by text the evening before with a live ETA sent 30 minutes out. Response times across West London run 30-45 minutes from the nearest depot for urgent call-outs; standard CP12 bookings are scheduled into a booked slot rather than dispatched as emergencies.

Yes. Uxbridge, Hayes and Ruislip are all within our standard coverage area across Hillingdon. Covering homes near Ruislip Lido, Colne Valley Regional Park, and the Battle of Britain Bunker museum. Every postcode in the borough — UB3–10 — is serviced at the same fixed pricing with no neighbourhood loading. Annual landlord portfolio contracts work across the full coverage area so a single property manager with flats in several of these neighbourhoods is invoiced against one consolidated account.

Fixed pricing applies across West London: £55-£75 for a single combi boiler in a Hillingdon flat, £75-£110 for a boiler plus hob, £110-£140 for three appliances, and £140-£220 for a licensed HMO with multiple boilers or water heaters. Landlords running three or more Hillingdon properties on an annual contract pay from £50 per property with consolidated monthly invoicing. No postcode loading applies within UB3–10.

Twelve months from the date of issue. Under Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998, every gas appliance, fitting and flue in a rented property must be checked for safety within twelve months of the last certificate. The renewal can be carried out up to two months before expiry and the original anniversary date is preserved, so you do not lose days off the annual cycle.

Yes. Our office handles the access scheduling — two reminder calls to the tenant, a text confirmation the evening before, and a documented record of all attempts. If the tenant refuses access we issue a headed letter of attempted access for the landlord's legal file, which matters if the matter later escalates to a court order. Regulation 36 expects reasonable attempts, not guaranteed access.

Yes, where access and engineer availability allow. Call before 11am and we can usually attend the same afternoon across most of London. Van-stocked spares mean that minor remedials such as a sticking isolation valve or a loose flue seal can often be sorted on the first visit so the certificate issues clean, avoiding a return call and a second booking fee.

Yes. Short-let hosts fall under the same Regulation 36 duty as any other landlord because each guest booking is a short tenancy. Booking.com, Airbnb and Vrbo all expect hosts to hold a valid in-date CP12, and most London boroughs with Additional HMO Licensing explicitly request it during inspection. The certificate number and issuing engineer's Gas Safe ID are also increasingly asked for during host platform listing verification.

Yes. Every gas appliance installed by the landlord is covered — boilers, cookers, hobs, gas fires, back boilers and water heaters. Appliances owned by the tenant (portable heaters, a tenant-supplied cooker) are not strictly within scope, but the engineer will still test the connection, isolation valve and bayonet fitting and note the appliance on the certificate for completeness.
