Key facts

Last reviewed:

A breakdown is stressful, and the repair bill makes it harder to choose. These are the main things to weigh up when deciding between a repair and a new boiler.

Age of the boiler

Many boilers last 10 to 15 years with regular servicing, though this varies by make and use. An older boiler may be less efficient and parts can become hard to find.

Cost of the repair

Repair labour is typically £90 - £150 including VAT, plus parts and the call-out fee. A common rule of thumb is to think about replacing when a repair costs a large share of a new boiler, especially on an older unit.

How often it breaks down

One fault on a well-kept boiler is usually worth repairing. Repeated breakdowns, or a boiler that needs several parts, point towards replacement.

Efficiency and running costs

Modern boilers are generally more efficient than older ones, which can reduce gas use. The saving depends on your home and how you use heating, so treat estimates with care.

Typical replacement prices

A combi boiler installation is typically £1,800 - £3,000 and a system boiler £2,500 - £4,000, including VAT. The price depends on the boiler, the flue and the work needed.
