A typical boiler installation project in Sevenoaks follows these steps:
A straightforward like-for-like combi boiler replacement usually takes one day. If the installation involves changing the boiler type (for example, from a conventional system to a combi) or relocating the boiler to a new position, allow two to three days.
In most cases, no. Boiler installations are covered by Building Regulations rather than planning permission. However, if your property is listed or in a conservation area, restrictions on external flue positions may apply. Your installer should advise.
For most 3-bed houses with one bathroom, a combi boiler rated at 28-35 kW is sufficient. If you have two or more bathrooms, a system boiler with a stored hot-water cylinder may provide better performance during peak demand.
