About this service
Baxi Boilers in South West London, done properly the first time
Baxi has been making boilers in the UK for over a century and its current 600 and 800 series are straightforward, well-priced units. Parts availability across South West London is good and older Baxi models remain very repairable, which is why we still service plenty of them.
Whether you need a straight Baxi swap, a move from a regular boiler and cylinder to a Baxi combi, or a diagnosis on a unit that keeps locking out, the work is carried out by our own Gas Safe engineers — never sub-contracted. We survey the property first, because the right answer in a three-storey Victorian terrace in New Kingston upon Thames is rarely the right answer in a two-bed flat in Putney.
On Baxi boilers the faults we are called to most are E119 — low system pressure; E133 — gas supply or ignition fault; E110 — overheat; E168 — general fault, often electrical. Most are repairable in a single visit once diagnosed properly, and we will always tell you plainly when a repair is not worth the money against a replacement.
Landlords and homeowners wanting reliable, well-supported units at sensible cost. If you are weighing Baxi against another manufacturer, ask us — we install every major UK brand, so we have no reason to steer you anywhere except the boiler that suits your property, your hot water demand and your budget.

Frequently asked
Your questions, answered
Do you install Baxi boilers in Kingston upon Thames?

Which Baxi models do you work on?

How much does a Baxi boiler cost to install?
We do not publish prices for boiler work, because the honest figure depends on the model, the state of your existing system, flue and condensate routes, gas pipe sizing and access. Send us a few details or call and we will give you a fixed written price for your property before anything is booked.
What warranty comes with a new Baxi boiler?
Warranty length depends on the specific Baxi model, the installation and registering the boiler with the manufacturer, so we confirm the exact terms in writing with your quote rather than quoting a headline figure. Annual servicing is normally a condition of keeping any manufacturer warranty valid. Our own workmanship guarantee sits on top of it.
Can you repair a Baxi boiler that has locked out?
Usually, yes. The faults we see most often on Baxi are E119 — low system pressure; E133 — gas supply or ignition fault; E110 — overheat. We diagnose first, tell you what the part and labour will be, and only then carry out the repair.
