Choosing a new boiler is one of the biggest heating decisions most homeowners will make.
With so many manufacturers available, many people naturally ask the same question first: which boiler brand is actually best?
The reality is there is no single boiler that suits every property. The best option depends on factors such as the size of the home, hot water usage, budget, energy efficiency goals and long-term reliability expectations.
