Know the Signs

Is It Time to Replace Your Boiler?

Don’t wait for a complete breakdown in the middle of winter. Here are the key warning signs that a new boiler installation could save you money and stress.

01

Boiler Over 10–15 Years Old

Older boilers lose efficiency over time and often can't meet modern energy standards. A new A-rated boiler can cut heating bills by up to 30%.

02

Frequent Breakdowns & Costly Repairs

If you're regularly calling out engineers, the repair costs are mounting up. A new installation is likely the more cost-effective long-term solution.

03

Rising Energy Bills

An inefficient boiler works harder and uses more fuel. If bills are climbing without explanation, your boiler's efficiency may be the culprit.

I needed advice about upgrading and moving the boiler from the kitchen to the airing cupboard. Jordan spent time taking through the options, answering my questions and gave me the reassurance that the job could be done without the pipe work showing. The outcome was excellent, really happy with the decision and quality of work and worth every penny! Would highly recommend Jordan and his team if you need any advice or work done

Fully recommend JTS. We just had our bathroom fully renovated and couldn’t be happier. Jordan and the team were great to work with from the start. Professional, efficient and tidy - couldn’t ask for more.

FAQ

Common Questions About Boiler Installation

A standard combi boiler replacement typically costs between £1,800 and £3,500. More complex installations — such as converting from a regular to a combi system, or larger properties — can range from £3,500 to £5,500. We provide a fixed, transparent quote before any work begins so there are no surprises.

No. UK law requires all gas boiler installations to be carried out by a Gas Safe registered engineer. DIY gas work is illegal and highly dangerous, and can invalidate your home insurance, void the boiler warranty, and risk carbon monoxide exposure. All our engineers are fully Gas Safe registered.

The correct boiler output depends on your property size, number of bathrooms, radiators, and hot water demand. Small flats typically suit a 24–27kW combi, while larger homes may need 30–40kW or a system boiler. Our engineers carry out a heat-loss calculation during your free survey to recommend the perfect match.

A like-for-like combi boiler swap is typically completed in one day. A system conversion or more complex installation may take 1–2 days. We work efficiently to minimise disruption and always leave your home clean and tidy.

Yes. All our installation work comes with a workmanship guarantee, in addition to the manufacturer’s warranty on your new boiler (typically 5–10 years depending on brand and model). We’re committed to getting it right first time, every time.

Absolutely. We’re available 7 days a week, including weekends, with no weekend surcharge. We also offer same-day and emergency boiler installation services for those situations where waiting simply isn’t an option.
