How Much Does a New Boiler Cost in Cardiff?

"How much for a new boiler?" is the question we get most from Cardiff homeowners. The honest answer is that it depends on your house — but the things that move the price are easy to explain.

What changes the price - **Boiler type.** A straight combi-for-combi swap is the simplest job. Converting from a conventional system with a tank in the loft is a bigger day's work. - **Where the boiler goes.** Moving a boiler from an airing cupboard to the kitchen means new gas, water, condensate and flue routes. - **Gas supply size.** Many older Cardiff terraces in Roath, Splott and Canton have 15mm gas pipe that needs upgrading to 22mm for a modern boiler. - **Flue position.** Long flue runs, plume kits near a neighbour's window, and scaffolding for high flues all add cost. - **Extras.** A magnetic filter, system flush and new controls are worth having and should be itemised, not hidden.

Combi conversions in older houses A lot of Cardiff housing stock is Victorian or Edwardian, with tanks in the loft and a cylinder upstairs. Converting to a combi frees up that space and gives instant hot water — but only if your mains water flow rate can support it. We test flow and pressure before quoting, never after.

What a fair quote includes Your written quote should state the boiler make and model, warranty length, whether a filter and flush are included, who removes the old boiler and tank, building control notification, and the total price with VAT. If a quote doesn't say those things, ask.

Why customers choose PHBLUE Our customers routinely say two things in their reviews: the price agreed is the price paid, and the house is left clean. As Edel in Cardiff put it after a tricky combi install in an older house: "On time, on estimate... and cleaned up as he went along."
