How much does a new boiler cost in Nottingham? (2026 guide)

Typical boiler replacement costs

For a straightforward combi-for-combi swap in a Nottingham home, most people pay between £1,800 and £3,500 supplied and fitted. The boiler itself is usually £900–£2,000; the rest is labour, parts (filters, valves) and removing the old unit.

Moving the boiler to a new location, upgrading from a conventional system to a combi, or fitting a larger system boiler for a bigger house can push the total to £3,500–£5,000+. A power flush, if your system needs it, typically adds £300–£700.

What affects the price

Boiler brand and warranty — a Worcester Bosch or Vaillant with a 10-year guarantee costs more up front but tends to be the better long-term buy.

How much pipework needs changing, whether you're relocating the boiler, and the controls you choose (a smart thermostat adds £150–£250).

Access and the state of your existing system — older systems sometimes need extra work to run a modern condensing boiler reliably.

How to avoid overpaying

Always get two or three quotes — prices for the exact same job genuinely vary by hundreds of pounds. Make sure each quote lists the boiler model, the warranty, and what's included (flush, filter, controls, making good).
