Our coverage in Greater London runs from Islington, Bexley, Barking and Sutton 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Questions
Can I keep my boiler and add a heat pump?
Yes, you can keep your boiler and add a heat pump as a hybrid system, where the heat pump usually handles most of the heating and the boiler helps on the coldest days or with hot water. A hybrid system is a guide price of £7,000–£11,000, installed and including VAT. Hybrid systems are not eligible for the Boiler Upgrade Scheme in England and Wales, so we compare both options with you at survey. See hybrid heat pumps.
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.
Should I leave my heat pump running all the time?
Usually yes: a heat pump works most efficiently running steadily at a low flow temperature, rather than switching on and off like many boilers. Weather compensation controls adjust the flow temperature to the weather outside, so the system keeps rooms comfortable using less energy. You can still lower temperatures overnight or when you are away, but large set-backs make the heat pump work harder to recover. We set up the controls and show you how they work.
What is included in the guide price for a heat pump system?
Our full-system guide price covers the outdoor heat pump unit, a hot water cylinder, controls, commissioning and typical minor pipework. Extras are priced separately only when your home needs them: a replacement radiator sized for a heat pump is a guide price of £250–£450 each, and a pipework upgrade is typically £1,500–£3,500. All are guide prices, installed and including VAT. Your written quote lists exactly what is included before you decide.
