Boiler replacement in Leicester
Typical costs shown first, then a fixed price from a Gas Safe registered Leicester installer.
Leicester homes, and the boilers they need
Leicester's housing runs from tight red-brick terraces near the centre, through interwar and postwar semis, to estates built since the 1990s on the city edge. Each has its own sensible choice. For a one-bathroom terrace, a compact combi is nearly always right. A busy semi may need a cylinder. We help you choose properly, then the price you are quoted is fixed.
Red-brick Victorian terraces: Most take a combi in the kitchen or rear lean-to. Where a terrace has been extended at the back, check the flue clears any neighbour's window before signing off the position.
Interwar and postwar semis: A combi is the default for one bathroom. Larger families who shower back to back may prefer a system boiler with a cylinder in the old airing cupboard.
Estates built from the 1990s onwards: Usually already on a combi with a short flue, so a like-for-like swap is quick. Check the gas pipe size if moving to a higher-output model.

Boiler replacement in Leicester: questions
How much should a new boiler cost in Leicester?
For a like-for-like combi swap, budget £2,200 to £3,400 fitted, VAT included. If you are converting from a tank-fed system to a combi, it is usually £3,000 to £4,200. You see the full figure in writing before agreeing to anything.
Can a new combi go where my old back boiler was?
Sometimes, but usually it moves to the kitchen or another outside wall, since a modern boiler needs its own flue and condensate drain. The old back boiler and its tanks are removed as part of the job.
My terrace has a rear extension. Does that affect the flue?
It can. Flues need set distances from windows, doors and boundaries, which an extension can make awkward. A longer flue or a plume kit usually solves it, and the installer checks this on the survey.
How long will the work take?
A combi replaced in the same spot is generally finished in a day. Moving the boiler or converting the system typically runs to a second day. Your installer confirms timings when they quote.
