If you currently have no heating or no hot water, you may need a repair first. See Emergency Boiler Repairs.
Many boilers can be repaired cost effectively. Replacement tends to make sense when the appliance is unreliable, parts are becoming difficult to source, or there are signs of major internal failure.
If repair costs are stacking up or a major component is failing (for example the heat exchanger or PCB), replacement can be the more reliable long-term fix.
Repeat breakdowns and frequent call outs

Choosing the right boiler depends on your hot water demand, property size, number of bathrooms, and how your current system is set up. We can advise on a like for like replacement or an upgrade where it suits the home.
A combi boiler heats water on demand and does not require a hot water cylinder. It suits many flats and smaller homes, and it can be a good option where space is limited.
A system boiler works with a hot water cylinder and can be better for homes with higher hot water demand, for example multiple bathrooms. It often provides stronger hot water delivery to more than one outlet.
A regular boiler is common in older systems that use a tank and cylinder. In some properties, it can be retained or replaced like for like where the existing setup suits the home.
