Is It Time to Replace Your Boiler? 7 Honest Signs
Repair or replace? Here's how Gas Safe engineers actually decide — and how to avoid being upsold.
Not every old boiler needs replacing. Here are the seven signs that tip the balance.
1. Your boiler is 12+ years old. Modern condensing boilers are 25%+ more efficient.
2. Repairs are stacking up. Three callouts in a year usually beats one big install bill within two years.
3. You've got rising gas bills with no other explanation. Worn boilers lose efficiency.
4. Parts are getting hard to source. Once a model is end-of-life, you're on borrowed time.
5. Frequent pressure loss with no visible leak. Often an expansion vessel — but on older boilers a sign of internal corrosion.
6. Cold spots in rads despite a recent service. Could be the system, not the boiler — get a power flush quote first.
7. You're extending or adding bathrooms. New demand often means a re-sized boiler.
At FFT we'll always quote both repair and replacement honestly — and tell you which makes more sense.
