Choosing the right size boiler depends on factors like the size of your home, the number of radiators, and your hot water usage. A small flat might require a 24-30kW boiler, whereas a larger home with multiple bathrooms might need a 35-42kW system.

A well-maintained boiler typically lasts 10 to 15 years. Regular servicing and prompt repairs can extend its lifespan. However, if your boiler is over a decade old and frequently breaking down or becoming less efficient, it may be more cost-effective to replace it with a newer, more energy-efficient model.

The cost of a new boiler can vary depending on the type, size, and brand, as well as installation fees. Here’s a general breakdown:

• Combi boilers: Typically range from £1,900 to £3,000, including installation.
• System boilers: Cost between £2,000 and £4,000, as they require a hot water cylinder.
• Regular (conventional) boilers: Prices start at £2,500 and can exceed £5,000 for larger systems, especially in older homes.

Additional factors such as upgrading pipework, removing the old boiler, or adding smart controls can affect the overall cost.
