Boiler replacement in Swindon
Typical prices for Swindon homes, from railway terraces to modern estates, then a fixed quote from a Gas Safe registered installer.
Picking the right boiler for a Swindon home
Swindon grew around the railway, so Victorian terraces still sit close to the centre, but much of the town is estate housing built from the 1970s onwards, plus newer developments on the edges. Estate homes usually make for a simple boiler swap. Older terraces can need more thought about the flue. Either way, we help you choose a boiler that suits your house and hot water use, at a fixed price.
Estates from the 1970s to today: Large parts of west and north Swindon are estate housing with modern flues, so swapping a combi or system boiler like for like is usually simple.
Victorian railway-era terraces: A compact combi suits these narrow houses. The flue route at the back, near small yards and neighbouring windows, is the main thing to check.
Postwar semis: A combi is fine with one bathroom. If a downstairs shower room or en suite has been added, a system boiler may be better.

Boiler replacement in Swindon: questions
What does a boiler replacement cost in Swindon?
Swapping an existing combi for a new one usually costs £2,200 to £3,400 fitted including VAT. Moving from a regular or system boiler to a combi, which means removing tanks, is typically £3,000 to £4,200. Your quote is fixed.
My estate house has a combi. Is a like-for-like swap simple?
Usually, yes. Most estate homes have a modern flue and pipework in sensible places, so a like-for-like swap is often done in a day. Your installer will still check the flue and gas supply meet current standards.
Will a new boiler fit my old terrace?
Almost certainly. Modern combis are compact. The main question is the flue route, as rules on distances from windows, doors and boundaries can limit options in narrow terraces. Your installer works this out on the survey.
How can I be sure the installer is properly registered?
Gas Safe registration is a legal requirement for anyone fitting a gas boiler. Ask for the engineer's ID card and look up the licence number online. We confirm registration for every Swindon installer before they quote.
