Boiler replacement in Exeter
Likely costs first, then a fixed quote from a Gas Safe registered Exeter installer.
Which boiler fits an Exeter home?
Exeter's homes range from Georgian and Victorian terraces close to the centre to large areas of interwar and post-war semis, with new-build estates growing on the eastern side. A small terrace or one-bathroom semi usually suits a combi. Taller townhouses and bigger family homes with several bathrooms often need a system boiler and cylinder instead. We help you choose, then match you with an installer at a fixed price.
Interwar and post-war semis: Most three-bed semis suit a combi if there is one main bathroom. Homes with a family bathroom plus an en suite get more reliable hot water from a system boiler and cylinder.
Victorian and Georgian terraces: A compact combi is usually enough for a smaller terrace. Larger townhouses over three or four floors may need a system boiler to reach every bathroom with decent pressure.
New-build estates on the edge of the city: Many already have a modern combi or system boiler, so a like-for-like swap is simple. Check the builder or manufacturer warranty before paying for any work.

Boiler replacement in Exeter: questions
How much is a new boiler in Exeter?
Replacing a combi with a new one usually costs £2,200 to £3,400 in Exeter, fitted and including VAT. A switch from a tank-fed system to a combi typically costs £3,000 to £4,200. The installer gives you a fixed written price before booking.
I live in a tall townhouse. Will a combi work?
It might, but hot water pressure can drop on the top floor, and two bathrooms at once may struggle. A system boiler with an unvented cylinder usually gives better flow on every floor. Your installer checks the mains supply before recommending.
My house is in a conservation area. Does that matter?
For a boiler swap inside the house, rarely. It can matter if a new flue terminal will be visible on the front of the building. Your installer will suggest a discreet route, usually at the back or side.
How can I check my Exeter installer is qualified?
Yes. City Boiler only connects Exeter homeowners with Gas Safe registered installers, and we check registration first. You can confirm the engineer's details on the Gas Safe Register website.
