Our coverage in Cornwall runs from Redruth, Falmouth, St Austell and Truro and the villages around them. The approach is the same everywhere: survey, design, a written quote, then installation by installers working under our contract.

Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Questions
Will an air source heat pump work in my home?
Most UK homes can use an air source heat pump, as long as there is space outside for the unit, room inside for a hot water cylinder and heating that can work at lower temperatures. Houses, bungalows, cottages and many flats are all possible. What decides the design is your home's heat loss, which we measure room by room at the free home survey. If a heat pump is not a good fit, we tell you and explain why.
Is there a heat pump grant in Northern Ireland?
There is no dedicated heat pump grant for homeowners in Northern Ireland at present. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire. The Boiler Upgrade Scheme covers England and Wales only, and Home Energy Scotland funding is for Scotland. Your written quote for a Northern Ireland home shows the price with no grant deducted unless funding has been confirmed.
What warranty comes with a heat pump?
A new heat pump comes with a manufacturer warranty, which passes to you, and the length depends on the make and model. Our workmanship guarantee is set out in writing in your quote. Manufacturer warranties usually depend on the system being registered and serviced as the manufacturer requires, so keep your handover pack, MCS certificate and service records together. We explain the warranty conditions for your chosen unit before you accept the quote.
What areas do you cover?
We cover the whole of the UK: England, Wales, Scotland and Northern Ireland. Installations on the Scottish islands and in other remote areas are by arrangement, as travel and access can affect timing and price. Grants, VAT and planning rules differ between nations, so your quote reflects where you live. Enter your postcode on our quote page or browse the areas we cover.
