Should I Repair or Replace My Boiler?

If your boiler has broken down — again — you’re probably wondering whether it’s time to stop throwing money at repairs and bite the bullet with a replacement. This guide will help you weigh up the key factors and make the best decision for your home and your wallet.

1. How Old Is Your Boiler?

Under 8 years old? Repairs are usually more cost-effective, especially if parts are still widely available.

Over 10–15 years old? It may be time to replace. Efficiency drops off, reliability worsens, and parts may be discontinued.

2. Is It Still Efficient?

Older boilers are often rated C or D efficiency — while new A-rated condensing boilers can save you up to £300 per year on gas bills. If your energy bills keep creeping up, that’s a sign your boiler may be working harder than it should.

3. Frequency of Breakdowns

One-off issues are worth repairing. But if your boiler has needed multiple call-outs in the last 12–18 months, those costs quickly add up. Constant loss of pressure, strange noises, and repeated fault codes are red flags.

4. Cost of Repair vs Cost of Replacement

If your repair quote is over £300–£400, and the boiler is nearing 10 years old, it may make more sense to invest in a new model — especially with new boiler packages starting from £1,900 fully installed.

PRO TIP: Consider the warranty. New Worcester boilers come with up to 10 years of cover — giving you peace of mind and lower long-term costs.

5. Are Parts Still Available?

Some older boiler models have discontinued parts, making even simple repairs impossible. We’ll always check this before quoting — but if your boiler is a rare or discontinued model, replacement may be your only option.

6. How Long Do You Plan to Stay?

If you’re planning to move in the next 6–12 months, a basic repair may be all you need to keep the heating running until you sell.

But if you're staying long term, a new boiler pays off in reliability, comfort, efficiency — and a better resale value.
