Boiler servicing in Harbury
Gas Boiler Servicing in Harbury covers a wide range of situations, from a straightforward planned visit through to a system that has failed completely. We handle both, and we are honest about which category your job falls into. We protect floors and worktops while we work and clear up properly afterwards. It sounds obvious, but it is the thing customers in Harbury mention most.
Property context
Housing across Harbury varies enough that no two jobs are quite the same. Older properties often hide a mix of copper, plastic and imperial pipework, while newer homes tend to run sealed systems with unvented cylinders.
Heating in the area
Most heating work in Harbury is gas, and we service, repair and install condensing combi, system and heat-only boilers from the main manufacturers. Properties off the gas grid are usually on oil, and we cover Grant, Firebird, Warmflow and Worcester oil boilers too.
Plumbing in the area
We handle day to day plumbing repairs in Harbury alongside larger projects such as bathrooms, ensuites, cylinder replacements and mains water boosters.

Harbury boiler servicing
Annual boiler service, gas or oil, done properly
Boiler servicing in Harbury and the surrounding Warwickshire area is our steady work through spring and summer. Most manufacturer warranties require an annual boiler service by a qualified engineer, miss a service and the warranty may be void.
Whether it is a gas boiler service on a combi, a system boiler service alongside a cylinder, or an OFTEC oil boiler service out in the villages, the job is boiler maintenance done to the manufacturer schedule rather than a quick look and a sticker.
A proper service is more than a quick visual check. We open the boiler, inspect the heat exchanger and burner, clean where required, check seals and gaskets, verify flue and combustion figures with a calibrated analyser, and check gas rate and system pressure.
Findings are written up on a service record so you have a paper trail for the warranty and any future sale of the property. If something needs replacing we tell you before we do it, explain why and give you the price.
For landlords, we combine the annual gas safety check (CP12) with a boiler service on the same visit, cheaper than two callouts and one less date to remember.
Common signs to look out for
- Boiler hasn't been serviced in the past 12 months
- Warranty terms require an annual service
- You're a landlord due a gas safety check
- Boiler is running noisier than it used to
- Yellow or lazy pilot flame on older boilers
- Fuel bills have risen without an obvious cause

For landlords
Combined CP12 gas safety + boiler service
For rented properties we combine the annual gas safety check and the boiler service on a single visit. We book with the tenant directly, produce the CP12 certificate the same day and send it to you or your letting agent by email.
For portfolios and letting agents we run a rolling reminder schedule so certificates never lapse and tenants aren't chased at short notice.
