Signs Your Boiler Needs Replacing

When Repair Isn't Enough

Boilers don't last forever. Knowing when to replace rather than repair can save you money in the long run and improve your home's energy efficiency. If you're unsure, a quick boiler service will give you a clear picture of your boiler's condition.

Age

Most boilers last 10 to 15 years. If yours is approaching or past this age, replacement should be on your radar even if it's still working.

Rising Energy Bills

If your gas bills are climbing despite no change in usage, your boiler's efficiency is likely declining. Modern A-rated boilers are 90%+ efficient compared to 60-70% for older models.

Frequent Breakdowns

If you're calling an engineer more than once a year for repairs, the cost of frequent fixes often exceeds the investment in a new boiler. Our central heating team can advise on the most cost-effective option for your home.

Strange Noises

Banging, clunking, or kettling noises indicate internal problems that may not be economically repairable.

Yellow Flame

A healthy boiler flame is blue. A yellow or orange flame could indicate incomplete combustion and potential carbon monoxide risk. This needs immediate attention — call us or use our emergency plumber service.
