An annual boiler service is the cheapest thing you will ever do for your heating system, and the most quietly profitable. It keeps your manufacturer’s warranty valid, catches the £120 fault before it becomes the £450 breakdown, claws back the efficiency that London’s hard water steals every year, and, the part that matters most, confirms your boiler is burning safely.
Average reply under 10 minutes. No obligation.
Our Gas Safe registered engineers carry out boiler servicing across every London borough, with fixed prices from £85, same-week appointments, and a written service record when we leave. Book once and we’ll remind you every year after; boilers don’t remember their own birthdays, and neither do busy Londoners.
“Service” is a word some firms stretch thin, a five-minute look and a sticker on the case. Ours follows the manufacturer’s schedule, which is what your warranty requires, and takes 45 minutes to an hour.
A repair in disguise. If the engineer finds a fault developing, you get a straight explanation and a fixed quote, never work done first and justified afterwards. Most services find nothing beyond a pressure top-up and a clean, and that's the outcome we're aiming for.
Most of the capital draws some of the hardest water in Britain.
Limescale is heating’s slowest, most expensive disease. It coats heat exchangers a layer at a time, forcing the boiler to burn more gas for the same warmth, and it’s the source of the kettling rumble our engineers hear from Croydon to Crouch End. A service catches scale early, when treatment is cheap; left for years, it ends in a heat exchanger replacement that costs more than a decade of servicing.
A modern boiler's seven-to-twelve-year warranty is conditional on annual servicing.
The conversions, extensions and relocated boilers that define the city's stock mean flues run in odd places.
Fixed price agreed before booking · Service fee counts toward any repair
If you let property in London, two annual obligations share one engineer’s visit: the legally required CP12 gas safety check and the boiler service your warranty and your void-avoidance both depend on. We combine them as standard, one tenant-access negotiation, one visit, two documents, digital copies to you and your agent the same day.
Portfolio landlords get a schedule: every property’s service and certificate dates tracked, renewals booked automatically ahead of expiry, one point of contact who knows your stock. A tenant with reliable heating renews; a January boiler failure in a tenanted flat is a compliance risk, a compensation conversation and a void risk rolled into one. Servicing is how landlords buy uneventful winters.
