How much does a combi boiler installation cost in Walsall?

A combi to combi swap starts from £2,000 fitted for a Baxi, £2,400 for an Ideal and £2,500 for a Worcester Bosch, including flue, filter, scale reducer, thermostat and powerflush. Converting from a regular or system boiler is from £2,800. Every quote is fixed.

Is a combi boiler right for my home?

For most Walsall homes with one bathroom, yes: no tank, no cylinder, no waiting for hot water and more cupboard space. If you have two or more bathrooms used at the same time, or poor mains water pressure, a system boiler may be better. We’ll check your flow rate before recommending.

Can you convert my regular or system boiler to a combi?

Yes. We remove the loft tank and hot water cylinder, run the new pipework and fit the combi. It usually takes two to three days and is quoted as a fixed price from £2,800.

Which size combi boiler do I need?

24kW suits most one bathroom homes. 30kW for larger homes or two bathrooms, 35kW and above for big houses with high hot water demand. Bigger isn’t better if the mains flow can’t feed it, which is why we measure it on the survey.

Which combi boiler brand is best?

Worcester Bosch for the 10 year warranty and reliability, Baxi if budget comes first, Ideal as a mid point. We fit all three from stock.

How long does a combi boiler installation take?

One day for a combi to combi swap, with heating and hot water back the same evening. Two to three days for a conversion. Next day fitting is usually available for swaps.
