Why we recommend Vaillant boilers
Vaillant have been building boilers since 1874 — long before central heating was a household expectation. Today they're consistently the most-recommended brand in independent UK trade surveys, prized for quality, reliability, high energy efficiency and genuinely responsive manufacturer support.
For homeowners who want a dependable, efficient heating system that won't be a headache in five years' time, Vaillant is the boiler we fit in our own family's homes — and the one we quietly recommend to everyone who asks.

Frequently asked questions
Are you a Vaillant Advance installer?
Yes. Dales Boiler Services is a Vaillant Advance company, which means our engineers are trained on the full Vaillant range, install to Vaillant's technical standards and can register your new boiler for its extended manufacturer warranty on your behalf.
Which Vaillant boiler is right for my home?
It depends on hot-water demand, radiator count and mains pressure. A 1–2 bathroom home usually suits an ecoTEC Plus combi; larger homes with two showers running together often need a system boiler with an unvented cylinder. We visit for free, take a proper look and recommend the right size — never oversell.
How much does a new Vaillant boiler cost in Brighton?
A straight combi swap on the same wall typically starts around £2,200 fitted. Full system upgrades, relocations or moves to a system boiler with cylinder are priced individually. Every quote is fixed, itemised and includes VAT, chemicals, flushing and commissioning.
How long does the installation take?
Most combi swaps are completed in one day. Full system changes or boiler relocations usually take two days. We protect floors, work tidily and leave the site clean.
What warranty comes with a Vaillant boiler?
Vaillant offers up to 10 years' manufacturer warranty on selected ecoTEC Plus models when installed by an Advance installer and registered within 30 days. We handle the registration for you and give you the paperwork on completion.
