Looking for air source heat pumps in Hemel Hempstead? We diagnose first, fix the price and book the work around you, then sign it off with written records.

Signs you need air source heat pumps in Hemel Hempstead
Air-to-air systems interest people who want cooling in summer as well as heating. They warm rooms directly through indoor units and switch to cooling in warm weather. The grant only applies in some cases, so we check first.
If any of these sounds familiar, it’s worth a diagnosis:
- Finding a place for the outdoor unit
- Questions about listed buildings or conservation areas
- Comparing heat pump types
High Elms Manor lies about 4.6 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
Questions to ask before booking
- Whether the price is fixed or an estimate
- Whether you get F-Gas records where refrigerant is involved
- Whether the manufacturer’s warranty depends on regular servicing
How we handle air source heat pumps in Hemel Hempstead
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, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. The work covers air-to-water heat pumps, hot water cylinders and air-to-air heat pumps, and common reasons people get in touch are working out where a cylinder could go and radiators that may be too small for a heat pump.
A place the size of Hemel Hempstead has homes of every age, and that matters for a heat pump. Every design starts with a room-by-room heat loss calculation, so the system is sized for your home and not guessed.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What air conditioning won’t do
Not every problem is solved by air source heat pumps, and we will tell you before we start. It won’t put right:
- Improving the building’s insulation
- Grants for hybrid systems or replacements of low-carbon systems
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If you’re not sure, just ring us on 07833 053749 or send an email and we will give you a straight answer.

What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Photos taken on a phone are often enough for us to plan a visit to Hemel Hempstead.
- You tell us about the home and what you want from a heat pump.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- After commissioning, you get the MCS certificate and a handover.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Plan for pets to be kept clear during the visit
- Move furniture away from the wall where we’ll be working

Heat pumps in Hemel Hempstead: local notes

FAQs for Hemel Hempstead
Will a heat pump in Hemel Hempstead need planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 10 listed entries sit within 0.5 miles of central Hemel Hempstead. 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 can’t face a road. Where necessary, we check with Dacorum council, which is typically the planning authority for Hemel Hempstead.
Is the heat pump grant available in Hemel Hempstead?
Yes, if the home and the heat pump meet the scheme’s rules: Hemel Hempstead is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we’re MCS certified.
Is Hemel Hempstead in your area?
Yes. Our area takes in London and the counties of the South East, and that includes Hemel Hempstead.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Which type of heat pump is right for my home?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water, and we explain which suits your home.
