Baxi is one of the UK's most trusted boiler manufacturers. We stock combi, system and heat-only models to suit homes of all sizes — from compact flats to larger family properties.
Baxi
System Boilers
Works with a separate hot water cylinder — well suited to larger homes with higher hot water demand. Baxi system boilers deliver consistent pressure throughout the house without a cold-water tank in the loft.

Baxi
Heat Only Boilers
Traditional open-vented boilers that work with a cold-water tank and hot water cylinder. The right choice when replacing an existing conventional system — no need to change the pipework layout.

01494 580033"Needed a very specific replacement part for a kitchen sink that is only available online at the major stores and wouldn't have been delivered for at least 5 days. With 5 minutes of entering the shop the very charming assistant found the exact part I needed. Excellent service thank you."
