Boiler replacement in Aberdeen
Typical prices for granite flats and family homes, then a fixed quote from a Gas Safe registered Aberdeen installer.
The right boiler for an Aberdeen home
Aberdeen's granite tenements and terraces fill the older parts of the city, from Rosemount to Torry, with postwar semis and newer estates further out. Solid granite walls are durable but cold, and long winters put boilers under steady load. That makes sizing important: too small and the house never warms up, too big and it wastes gas. We will help you pick a boiler that fits, at a fixed price.
Granite tenement flats: A combi in the kitchen or a hall cupboard is the norm. Running a flue through solid granite takes the right tools, so expect the installer to survey the wall closely.
Postwar and later suburban semis: A combi suits most of these homes with a single bathroom. Families with two bathrooms in use at once may prefer a system boiler and cylinder.
Granite villas and larger detached houses: Big rooms and many radiators often call for a system boiler with a cylinder. On the edge of the city, some homes run on oil rather than mains gas.

Boiler replacement in Aberdeen: questions
What does a new boiler cost in Aberdeen?
A combi swapped for a new combi normally costs £2,200 to £3,400 fitted including VAT. Converting from a system with a tank or cylinder to a combi is usually £3,000 to £4,200. The price you agree is fixed.
Can a flue go through a granite wall?
Yes. Installers core-drill through granite regularly, though it takes longer than brick. Where possible, reusing the existing flue hole keeps the cost and disruption down. Your installer will check the route on the survey.
Is a bigger boiler better for a cold granite house?
Not necessarily. An oversized boiler cycles on and off and wastes fuel. What matters is the heat loss of your home. A good installer works this out room by room and sizes the boiler and radiators to match.
Is there help with heating costs in Scotland?
Home Energy Scotland gives free advice and runs support schemes, mainly for insulation and cleaner heating such as heat pumps. Ask them what you might be eligible for before you commit to a new system.
