We’ll provide a fully transparent quote, and once you’re ready to proceed, we’ll schedule your installation at a time that suits you.

Types of Glow-worm boiler
Glow-worm offers three main types of boilers to suit different home setups.
Combi boilers are ideal for smaller homes, offering hot water on demand without a storage cylinder.
System boilers include a hot water cylinder and are great for homes with higher demand.
Regular (heat-only) boilers work with a traditional setup and are ideal for properties with a hot water tank and cold-water feed.

Glow-worm boiler replacement
If your current boiler is on its last legs – noisy, unreliable, or inefficient – it may be time for a replacement. Upgrading to a modern Glow-worm boiler can significantly improve your home’s comfort and energy efficiency.
We’ll inspect your system, recommend the right replacement model, and handle the changeover with minimal disruption. Most Glow-worm boiler installations are completed in just one to two days.

Easy to get hold of, came out quickly, identified the problem and did a temporary fix then returned the following day for a proper fix with the part needed. On time, courteous and clean. Have used JPS Plumbing and Heating before and will definitely use again.
