Air source heat pumps in Harpenden
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb is not good enough. The work covers hot water cylinders, air-to-water heat pumps and air-to-air heat pumps, and the jobs we see most are deciding on the outdoor unit position and planning and permitted development questions.
Older homes in a town like Harpenden can still suit a heat pump, though some need bigger radiators or better insulation first. We work that out from a heat loss calculation.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Questions from Harpenden
Can I get the Boiler Upgrade Scheme grant in Harpenden?
Yes, the scheme covers homes in England, including Harpenden, if they qualify. 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 a heat pump in Harpenden permitted development?
That depends on the building and where the outdoor unit goes. The Harpenden Conservation Area takes in the middle of Harpenden. 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 St Albans City council, which is typically the planning authority for Harpenden first.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
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.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
System by system
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. Cooling-only units are not included, so check with the council.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
How the visit works
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. In a town like Harpenden, parking is normally straightforward, so the main questions are access and timing.
- 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 recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
How to prepare
- Let us know where the consumer unit is
- Tell us about any building rules, permits or sign-in
- Clear a path to the units and the space around them

Safe owner checks
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring us on 07833 053749 or drop us a line.
A customer’s words
