Is It Time?
Signs your boiler may need replacing
Not every problem needs a new boiler. These are the signs worth a conversation.
Slow or uneven heat
Radiators take a long time to warm up, or the hot water runs cold halfway through a shower.
Rising running costs
Your gas bills keep going up although you’re using your heating the same way.
An older boiler
Older boilers are often less efficient, and replacement parts can become harder to find.
Not sure yet? A repair may be the better choice. Boiler fault finding & diagnosis from £120 ↗

Three types of boiler. One right for your home.
Which type suits you depends on your home, your hot water use and the system you have now.
