Air source heat pumps for homes and businesses in Kemprow
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. Typical jobs include a boiler that’s getting old and working out whether radiators need upsizing, on homes heated by oil, LPG or gas, underfloor heating and air-to-water heat pumps.
Space for an outdoor unit is rarely an issue near Kemprow, so the design focuses on heat loss and radiators.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

What we do, step by step
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. We agree a date with you and plan the visit to Kemprow so we arrive with what’s needed.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit

Heat pumps in Kemprow: local notes
Census 2021 figures found about 71% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder.
Historic houses such as High Elms Manor, about 2.7 miles north-west, are a reminder that listed homes need consent before a heat pump goes in. Period properties close to St John can suit a heat pump, though insulation and any heritage protection are checked first.

Common questions in Kemprow
Do I need planning permission for a heat pump in Kemprow?
It comes down to the building and the spot chosen for the outdoor unit. Around 9 listed entries sit within 0.5 miles of central Kemprow. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with the local planning authority (for Kemprow, usually Hertsmere council).
Does the Boiler Upgrade Scheme cover homes in Kemprow?
Kemprow is in England, where the Boiler Upgrade Scheme runs. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before any work starts, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
What does an air-to-water heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.

Air-to-water heat pumps
The price for air-to-water is £8,000–£16,000 (0% VAT on homes), before the grant. A £7,500 grant may be available through the Boiler Upgrade Scheme for eligible homes and the installer applies.
Heat loss surveys
The survey works out the heat needed room by room. Everything else is sized from it.
Before you call an engineer
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749, or email if that’s easier.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
