## The honest answer depends on your boiler

There is no universal rule. But there are clear signs that point one way or the other.

## When a repair makes sense

Your boiler is **under 8 years old** and regularly serviced. The fault is a known, fixable issue. The repair cost is **under £400**.

## When replacement is better value

Your boiler is **over 10 years old**. You face **frequent breakdowns**. Repair costs are approaching £1,000+. Parts are discontinued.

## What does a new boiler cost?

A new boiler installation typically costs **£2,500 to £4,500**. A new A-rated boiler can save £300 to £500 per year on energy bills.

## Our approach

We give honest advice. If a repair makes sense, we will tell you. If replacement is better value, we will explain why — with real numbers, not pressure.
