/ What's included in an installation
Choosing a new boiler starts with the right size and the right type for the house — not the biggest one on the price list. We survey the property, look at your hot-water demand and radiator count, and recommend a combi, system or regular boiler that fits how you actually live.
Installation is done by Gas Safe registered engineers to the manufacturer's instructions, which is what keeps the warranty valid. The system is flushed, a magnetic filter is fitted, the boiler is commissioned with test readings recorded, and you get the Building Regulations certificate and a walkthrough of the controls before we leave.
Most like-for-like replacements are finished in a day; conversions from a regular boiler to a combi, or a relocation, take longer and are quoted accordingly. Every quote is fixed and in writing.

/ Boiler installation cost in Basingstoke
The cost of a new boiler depends on three things: the boiler itself, the type of system (a like-for-like combi swap costs far less than a conversion from a regular boiler with tanks), and how much pipework, flue or controls need changing. We survey the property and give you one fixed price covering the boiler, labour, system flush, magnetic filter, disposal of the old boiler and the certificate — nothing added later.
/ Covering RG21 to RG24 — Festival Place, Chineham, Brighton Hill and Old Basing
Much of Basingstoke was built in a few decades of rapid expansion, so whole streets tend to reach the boiler-replacement stage at the same time. We do a lot of like-for-like combi replacements on the estates and system upgrades in the older parts of town. Hampshire's water is hard, and we fit scale reducers on new installs as standard where the supply calls for it.
We cover the whole of Basingstoke (RG21 to RG24) — from Festival Place, Chineham, Brighton Hill and Old Basing — and the surrounding areas including Chineham, Old Basing, Hook, Tadley, Overton, Whitchurch, Oakley and Kempshott. Typical housing here is large 1960s–80s estates from the town's expansion, plus newer developments at Chineham and Sherfield Park, and our engineers know the boiler types, flue positions and system layouts that go with it.
We're based in Woking, Surrey, roughly 25 minutes from Basingstoke in typical traffic — a normal working day for us, not a special trip.
Same-day appointments are available for most of Basingstoke, and every job — a service, a repair or a full installation — comes with a fixed price agreed before we start and a written record when we're done.

Straight answers. If yours isn't here, call — it's quicker than a form.
How much does a new boiler cost?
It depends on the boiler, the type of system and how much pipework needs changing. A straightforward like-for-like combi swap costs a lot less than a conversion or relocation. Request a fixed-price quote and we'll survey and price it in writing.
Combi, system or regular — which do I need?
Combis suit most flats and smaller homes with one bathroom. System and regular boilers with a cylinder suit larger homes with two or more bathrooms in use at once. We'll recommend based on your hot-water demand, not on price.
How long does a boiler installation take?
A like-for-like replacement is usually one day. A conversion, relocation or a system with a new cylinder is typically two days.
Do I get a warranty?
Yes. We install to manufacturer requirements and register the warranty for you — typically between five and ten years depending on the model.
Do you take the old boiler away?
Yes, removal and disposal of the old boiler is included in the quote.
