What are the signs you need a new boiler?
Is your boiler trying to tell you something? It could be time for a replacement if it’s over 10–15 years old, struggling to heat your home, making strange noises, or raising your energy bills. Other red flags include frequent breakdowns or a yellow flame—an urgent safety concern.
Older boilers can be just 60% efficient, wasting up to 40% of your heating energy, while modern A-rated models are over 90% efficient. According to the Energy Saving Trust, upgrading could save you £125–£490 a year. Don’t ignore the signs; invest in comfort, safety, and long-term savings.
