Frequently Asked Questions
How do I know if I need a new boiler?
If your boiler is over 10 years old, needs frequent repairs, or your energy bills are rising, a new boiler is likely the better investment. We'll give you honest advice on whether a repair or replacement makes more sense.
What size boiler do I need?
Boiler size depends on your home — number of bedrooms, bathrooms, and radiators. During our free survey, we'll calculate exactly what you need. Most 3-bed homes suit a 28-32kW combi boiler.
How long is the warranty on a new boiler?
As approved installers, we can offer up to 12-year warranties on Worcester Bosch, Vaillant, and Ideal boilers. The warranty covers both parts and labour.
