From survey to warm house
Four steps, no drama. A swap is a one-day job — water and gas off in the morning, back on the same evening.
- 1
Survey
We look at the gas meter and supply pipe, count radiators, check flue routes and water pressure. Around fifteen minutes, no charge.
- 2
Fixed quote
Written, itemised, and it does not move unless you change the scope.
- 3
Install day
Water and gas off in the morning, back on the same evening for a swap. A conversion or a boiler move normally takes two days.
- 4
Handover
We set the controls, run you through the thermostat, register the warranty and leave the paperwork.
Fixed prices, not estimates that drift
The figure we quote is the figure you pay, unless the scope changes — and the survey is there to catch anything unusual before you commit.
| Job | Warranty | Fitted price |
|---|---|---|
| Baxi / Main Eco Compact — combi swap | 5 yr | £1,999 |
| Baxi 600 — combi swap | 7 yr | £2,199 |
| Worcester Greenstar 4000 — combi swap | 10 yr | £2,699 |
| Worcester Greenstar 8000 — combi swap | 10 yr | £2,899 |
| Conversion to combi (from system or open vent) | — | from £2,699 |
Every price includes the boiler, horizontal flue, wireless thermostat, magnetic filter, system cleanse and inhibitor, Building Regulations notification, and removal of the old boiler. Same-position swaps. Estimates confirmed after a free survey.
