A new boiler may be needed if your current one is over 10–15 years old, breaks down often, struggles to heat your home, or causes rising energy bills. A professional survey can confirm whether repair or replacement is the best option.
Most installations take 1–2 days, depending on the type of boiler and complexity of the job. Converting from a system or back boiler to a combi boiler may take a little longer.
The right boiler depends on the size of your home, the number of bathrooms, and your hot water needs. Common options include combi, system, and regular boilers. An engineer can recommend the best fit after a site visit.
Clear access to the boiler location and surrounding areas helps the engineer work safely and efficiently. If your boiler is in a kitchen or cupboard, removing any items in advance will speed up the process.
