Boiler replacement in Leeds
A fixed price from a Gas Safe registered Leeds installer. Most combi swaps are fitted in a day.
Leeds homes, and the boilers that suit them
Leeds has a mix of Victorian terraces, including thousands of back-to-backs, 1930s semis in the suburbs and modern flats in the centre. The right boiler depends on your home, your hot water use and how easy it is to run a flue. We will help you choose the best fit, then an installer fixes the price.
Victorian terraces and back-to-backs: A compact combi usually fits the old chimney-breast cupboard. Back-to-backs have one outside wall, so plan the flue route first.
1930s semis: A combi suits one bathroom. Two bathrooms or a busy household usually need a system boiler and cylinder.
City-centre flats: Check the flue route and any building rules before choosing a model. Some blocks need a specific flue type.

Boiler replacement in Leeds: questions
How much is a new boiler in Leeds?
Most combi to combi swaps in Leeds cost between £2,200 and £3,400 fitted, including VAT. Converting from a system or regular boiler to a combi costs more because pipework and the loft tank change. You get a fixed price in writing before any work starts.
How long does a boiler swap take?
A like-for-like combi swap is normally done in one day. Moving the boiler or converting to a combi usually takes one to two days. Your installer confirms the timing on the survey.
Do I need to be in during the install?
Someone needs to be home at the start to let the engineer in and agree where everything goes, and at the end to be shown how the new controls work. You do not need to stay in all day.
Is my installer Gas Safe registered?
Yes. Every boiler installer City Boiler works with in Leeds is Gas Safe registered, and we check before they quote. You can also check the engineer's ID card number on the Gas Safe Register website.
