What affects the price
- Boiler brand and warranty — budget boilers carry 2–5 year warranties; premium models reach 12–14 years for a few hundred pounds more.
- Like-for-like versus conversion — converting from a tank system adds a day of labour and pipework.
- Location moves — relocating the boiler means a new flue route and longer pipe runs.
- System condition — sludge and scale in an old system need flushing before the new boiler goes in.
- Controls — smart thermostats and new programmers add £150–£350 fitted.
How Much Does a New Boiler Cost in Teesside: common questions
How long does a boiler replacement take?
A straightforward like-for-like combi swap is usually done in one day. Conversions from a tank system or relocations take one to two days. You'll normally have heating and hot water back the same evening on a simple swap.
Is it worth paying more for a premium boiler?
Usually, yes. The gap between a budget and premium boiler is often £400–£600, but the premium model carries a warranty of up to 12–14 years versus 2–5, and tends to be cheaper to repair. Over the boiler's life the premium option is often better value.
How do I check an engineer is Gas Safe registered?
Ask for their Gas Safe ID card and check the back lists the work you're hiring them for, or verify their licence number on the Gas Safe Register website. It is a legal requirement for any gas work, not a nice-to-have.
Does a new boiler need servicing to keep the warranty?
Yes, almost all manufacturers require an annual service by a Gas Safe engineer to keep the warranty valid. Budget £80–£120 a year, and keep the service records.
