What affects the cost of a new boiler?

The cost of a new boiler varies with your home and the work involved. Rather than quote invented figures, this guide explains the factors that shape a quote so you can compare fairly.

The main factors

Boiler type: combi, system or conventional.
The size or output needed for your home and hot-water demand.
Whether you keep the same boiler type or change to another.
Moving the boiler to a new location.
Additional work such as a system flush, new controls or pipework.

Why a like-for-like swap usually costs less

Replacing a boiler with the same type in the same place is typically simpler than switching types or relocating it, which can involve extra pipework and time.

What to ask for in a quote

A clear breakdown of the boiler, parts and labour.
Whether a system flush and new controls are included.
The warranty offered and what registration is required.
Confirmation that gas work will be done by a suitably registered engineer.

Verifying gas work

Boiler installation is gas work and must be carried out by an appropriately registered engineer. You can check registration on the official Gas Safe Register before work begins.

Questions

Frequently asked questions

Is the cheapest boiler quote the best value?

Not always. Compare what is included, the warranty, the engineer's registration and the quality of the boiler, not just the headline price.

Do I need my boiler serviced to keep the warranty?

Many manufacturers require an annual service by a registered engineer to keep the warranty valid. Check the terms for your specific boiler.
