About our air source heat pumps in Whitwell
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it doesn’t apply to businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. The work covers hot water cylinders, radiator systems and air-to-air heat pumps, and people most often call us about radiators that may be too small for a heat pump and a boiler that’s getting old.
Space for an outdoor unit is rarely an issue near Whitwell, so the design comes down to heat loss, radiators and hot water.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Questions from Whitwell
Is planning permission needed for a heat pump in Whitwell?
The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Whitwell Conservation Area, close to central Whitwell. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at North Hertfordshire council, normally the authority for Whitwell.
Do you cover smaller places like Whitwell?
Yes. Whitwell is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Will my home qualify for the Boiler Upgrade Scheme?
That depends on the scheme conditions, which we check for you. As the installer, we make the application where you qualify.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
What’s the price of a heat pump installation?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. The heat pump size, radiator changes and the cylinder decide where in that range you are, and air-to-air systems are priced after a survey.
How quickly will you reply?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
What happens if it’s left?
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. It’s a date to bear in mind when planning, though the right time also depends on your home and heating. Planning ahead for a job in Whitwell means we can bring everything needed.
What you pay depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before we start, so you know where you stand.

What else we do in Whitwell
What happens on the day
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes from a couple of days to around a week, depending on the system and how much of the heating changes. We plan the trip to Whitwell around you.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Tell us about parking and loading
- Mention any managing agent or landlord rules we need to follow
Get a fixed-price quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

With Shaw's Corner about 2.9 miles south, it’s worth asking whether your own home is listed before planning a heat pump. If your home is one of the older properties near All Saints Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Looking after your system
Simple habits make a real difference. We recommend:
- Ask about the grant before you commit
- Use the settings explained at handover
- Check what your manufacturer’s warranty asks of you
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
