We do one thing and we do it exceptionally well: Vaillant boilers. Our entire focus – from training to tooling to parts – is centred on the Vaillant range, meaning you always get specialist attention rather than a generic service.
Our engineers train exclusively on the Vaillant range. We understand the quirks, the common faults, and the best solutions for every model in the ecoTEC and ecoFIT families. When you call VaillantCare, you speak directly to someone who knows your boiler inside and out.
Every engineer on our team holds a current Gas Safe registration. We never subcontract to unqualified third parties, and all work is documented to the highest industry standards, including full Benchmark completion on new installations.
We quote upfront, in writing, before we begin any work. There are no hidden call-out fees buried in small print, and no surprise labour charges added after the fact. What we quote is what you pay – it's that simple.
We fit only manufacturer-approved genuine Vaillant parts on every repair and installation. Using genuine components protects your warranty, ensures correct operation, and extends the lifespan of your appliance significantly over cheaper alternatives.
We know that a broken boiler is never convenient. Our scheduling system is built for speed, with same-day emergency slots available and next-day appointments as standard. We'll give you a two-hour arrival window so you can plan your day around us, not the other way round.
All our work is covered by comprehensive public liability insurance. Every job is logged with a completion report, and all new installations are registered with the appropriate Building Regulations notification scheme, protecting you as the homeowner.
From brand-new installations to urgent repairs, we cover every aspect of Vaillant boiler ownership.
