Norwich homes, and which boilers suit them
Most Norwich homes are semis from the interwar and postwar years, with Victorian terraces closer to the centre and plenty of bungalows on the edges of the city. For a one-bathroom semi or bungalow, a combi is usually right. Bigger households may be better off keeping a cylinder. We help you choose sensibly, then your price is fixed in writing.
Interwar and postwar semis: A combi is the natural choice for a single bathroom. Where the household is large or water pressure is low, keep a cylinder and fit a system boiler instead.
Victorian terraces inside the ring road: Combis usually sit on the kitchen wall. In homes with a narrow side passage, check the flue terminal clears the neighbour's windows and the shared path.
Bungalows on the city edge: Combis suit most bungalows well, with short pipe runs and one bathroom. If there is no loft hatch near the boiler, plan the flue through a side wall.

Boiler replacement in Norwich: questions
What does a new boiler cost in Norwich?
Replacing a combi with a combi is generally £2,200 to £3,400 fitted, VAT included. Converting a tank-fed system to a combi usually comes to £3,000 to £4,200. You get a fixed figure before any work begins.
Is a combi a good idea for a bungalow?
Usually, yes. Bungalows tend to have one bathroom and short pipe runs, which suits a combi well. Removing the old tanks also frees up space in the loft or airing cupboard.
I live just outside Norwich and use oil. Can I switch to gas?
Only if your property has, or can get, a mains gas connection. If not, a new oil boiler or an air source heat pump are the usual options. We can help you compare both.
How quickly can a Norwich installer fit my new boiler?
It depends on installer availability and the job. A like-for-like combi swap is normally completed in one day once booked. Your installer gives you a fit date with the quote.
