Central Heating Installation
Our Gas Safe-registered central heating engineers work on properties of all shapes and sizes in and around Swindon, Cirencester, and Marlborough. If you struggle to heat your property evenly, find your boiler unreliable and prone to faults and breakdowns, or are concerned about the impact of old infrastructure on steadily rising energy bills, it’s well worth speaking with our team.
We handle every aspect of an upgrade or new-build fit-out, including installing meters, radiators, pipes, boilers, and other elements to ensure a reliable, effective system, before issuing the necessary certification. We’ll even draw up a map so that, should you require maintenance or central heating repairs in the future, they can be tackled without undue cost or delay.
With a wide range of industry-leading brands on offer, you can trust our team to find the perfect combination of products to meet your needs and budget. BJS Heating & Fires proudly installs boilers from:

We go to great lengths to minimise disruption during our central heating installations and always leave properties in the same state we found them (only with a new and improved heating system).
If you only require particular elements of a central heating system to be added, replaced, or upgraded, we’re happy to fit new pipes, radiators, and similar essentials on a standalone basis.

FAQs – Central Heating
There are several signs that your central heating system may need to be replaced. If your radiators take a long time to heat up, your boiler breaks down frequently, or your energy bills are steadily increasing, your system could be working inefficiently. Older systems can also struggle to maintain consistent temperatures throughout your home. A modern central heating installation can improve efficiency, reduce running costs, and provide more reliable performance.
A full central heating installation typically includes fitting a new boiler, radiators, pipework, and controls such as thermostats and timers. Our central heating engineers will assess your property, design a system that suits your layout, and ensure everything is installed safely and efficiently. We also test the system thoroughly and provide certification, so you can be confident everything is working exactly as it should from day one.
It’s recommended to have your system checked at least once a year to keep it running safely and efficiently. Regular maintenance helps detect small issues before they become costly repairs, improves performance, and extends your system’s lifespan. Routine checks can include inspecting radiators, checking pressure levels, cleaning components, and ensuring your boiler is operating correctly.
In many cases, repairs can restore performance and improve efficiency, especially if the issue is limited to a specific component, such as a pump, valve, or thermostat. However, if your system is older or requires frequent repairs, our central heating replacement service may be the more cost-effective long-term option. We’ll always assess your system honestly and recommend the best solution based on your needs and budget.
