Real price ranges first, then a fixed quote from a Gas Safe registered installer working across Brighton and Hove.
Brighton homes, and the boilers that work in them
A lot of Brighton's housing is tall Regency and Victorian buildings split into flats, alongside hillside terraces and interwar semis to the north. In a flat, the flue route usually settles the choice. In a house, it comes down to how many bathrooms you have and how strong your mains water is. We help you choose the right boiler, then the price is fixed.
Flats in converted Regency and Victorian houses: The boiler often sits in a kitchen or hall cupboard far from an outside wall, so the flue route decides what is possible. Lease terms may also set rules on where flues can go.
Victorian terraces on the hills: A combi usually fits in the kitchen or a loft-conversion cupboard. Narrow, steep streets can make access and parking slow, so build that into the day.
Interwar semis in the northern suburbs: Combis suit most of these homes. Where a loft conversion has added a second bathroom, a system boiler and cylinder deal better with demand.

Boiler replacement in Brighton: questions
How much does a boiler replacement cost in Brighton?
For a combi to combi swap, most people pay £2,200 to £3,400 fitted, with VAT included. If the job involves converting a tank-fed system to a combi, it is usually £3,000 to £4,200. Everything is agreed in a fixed quote.
Do I need permission to replace the boiler in my leasehold flat?
A like-for-like swap often needs none, but some leases require you to tell the freeholder, especially if the flue position changes. Check your lease before booking. Your installer can supply the details the freeholder may ask for.
Does sea air affect a new boiler?
Salt air can corrode flue terminals and pipework faster on homes close to the seafront. It is worth asking your installer about the flue finish and keeping up with annual servicing.
Can a combi be fitted in a loft conversion?
Often, yes, as long as there is a safe flue route and the condensate pipe can drain. It is a common way to free up space in Brighton's narrower houses. The installer checks access and pipe runs on the survey.
