Air source heat pumps in Cooper's Green, done properly
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers air-to-air heat pumps, homes heated by oil, LPG or gas and hot water cylinders, and common reasons people get in touch are an oil, LPG or gas boiler near the end of its life and wanting to stop using oil, LPG or gas for heating.
In a place like Cooper's Green, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Air source heat pumps around Cooper's Green

How it works
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. We plan the trip to Cooper's Green around you.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- 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.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Clear a path to the units and the space around them
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets and children away from the work area
Getting a quote
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then call 07833 053749.

FAQs for Cooper's Green
Can I get the Boiler Upgrade Scheme grant in Cooper's Green?
Yes, if the home and the heat pump meet the scheme’s rules: Cooper's Green is in England, where it applies. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Can I fit a heat pump in Cooper's Green without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 3 buildings and structures within half a mile of the centre of Cooper's Green. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Cooper's Green, normally Welwyn Hatfield council) first.
Do you provide F-Gas records?
Yes. You get a written record of each visit, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Which accreditations do you hold?
We’re an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Which manufacturers do you install and repair?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
What air source heat pumps can’t fix
Air source heat pumps cannot fix everything, and we’d rather say so up front. It won’t put right:
- Formal advice on VAT for your situation
- Insulation work, such as loft or cavity wall insulation
- Disconnecting or servicing a gas boiler
If you’re not sure, just call us on 07833 053749 or send an email and we will give you a straight answer.
