And we don't cut corners on the bits you can't see — proper pipework, magnetic filter, full system flush where needed.

Things Thaxted customers usually ask about boiler installs
Why pick Vaillant over Worcester?▾
Vaillant tends to edge ahead on hot-water performance and very-quiet operation. Worcester edges ahead on warranty length and parts availability outside London. We'll be honest about which fits your situation.

Common parts (PRVs, expansion vessels, F22 sensors) yes — on the van. Less common parts come next-day from Vaillant directly.
How much does a new boiler cost fitted?▾
Most combi swaps run £2,200–£3,800 fitted depending on brand and any system upgrades. We give you a written fixed price after a free survey — no obligation.
