New boiler installation in Liverpool
Get fixed quotes for a new combi, system or regular boiler from Gas Safe registered installers covering Liverpool.
With 77.8% of Liverpool households heating with mains gas alone, a replacement gas boiler is the most common heating job in the city. For a typical terrace, a combi in the same spot as the old one is the simplest, cheapest choice.
Bigger homes in Woolton, Allerton and Childwall with two bathrooms may be better with a system boiler and cylinder, which also keeps a heat pump easier to fit later.

Back boiler removals
Many post-war Liverpool semis still have, or had, a back boiler behind the living room gas fire. Replacing one means a new boiler location, new pipework to the kitchen or a bedroom and usually removing a hot water cylinder and loft tank. Expect a two to three day job and some making good.
Ask the installer how they will deal with the old flue and the chimney, and who will cap the gas fire if you're not keeping it.
Reading the quotes side by side
Line up quotes on the same basis: boiler model, warranty years, filter, controls, the type of system clean and Building Regulations notification. For a sense of whether a price is fair, check it against the ranges in our new boiler cost guide.
A cheap quote that skips the flush often means a new boiler fed by dirty water. That shortens its life whatever brand you choose.
Controls and paperwork
Building Regulations require suitable controls with a new boiler, typically a room thermostat, timer and thermostatic radiator valves. A smart thermostat can cover the first two. Your installer should register the job with Gas Safe, after which you'll get a Building Regulations compliance certificate in the post, so keep it for when you sell.
Choosing a boiler for your home
Victorian and Edwardian red-brick terraces
A mid-sized combi suits most terraces with one bathroom. If the kitchen is at the back, a vertical flue through a flat-roofed rear extension may be the neatest route.
Interwar and post-war semis
If you're keeping a cylinder, a system boiler with an unvented cylinder gives mains-pressure showers without a loft tank.
City-centre apartments and converted houses
In converted houses, flue terminals must stay clear of neighbours' windows. A plume kit can direct vapour away from a light well or shared yard.

Questions people in Liverpool ask
Can I get help paying for a new gas boiler in Liverpool?
The Warm Homes: Local Grant focuses on insulation and low-carbon heating rather than gas boilers. See our Liverpool heating grants page for what's open.
Does soft water mean I don't need a filter?
No. The filter catches iron oxide from radiators, not limescale. It is worth fitting whatever your water hardness.
