Advice
Air source heat pumps in Great Gaddesden, done properly
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. We check each radiator against the room’s heat loss, and the quote sets it out. Common call-outs are for checking emitters for a heat pump and replacing a combi boiler with a heat pump, on air-to-air heat pumps, underfloor heating and homes heated by oil, LPG or gas.
Older and listed homes in villages like Great Gaddesden need extra care, 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: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

FAQs for Great Gaddesden
Is planning permission needed for a heat pump in Great Gaddesden?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Great Gaddesden Conservation Area, close to central Great Gaddesden. 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 Great Gaddesden, usually Dacorum council) first.
Is the heat pump grant available in Great Gaddesden?
Yes, if the home and the heat pump meet the scheme’s rules: Great Gaddesden is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You don’t apply yourself: the MCS certified installer does, which is us.
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.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
Do you have a 24/7 line?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
Is Great Gaddesden in your area?
Yes. Our area takes in London and the counties of the South East, Great Gaddesden included.
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. Any work is priced before it goes ahead.
Air source heat pumps in Great Gaddesden: the local picture
The Valuation Office Agency’s council tax figures date about 73% of homes across Great Gaddesden and its surrounding area to the post-war years, 1945 to 1972, and Census 2021 figures found about 52% of households in terraced houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
A heat loss calculation decides the size of heat pump your home needs.

Keeping the system healthy
How well a system lasts depends on use and care. Here’s what we suggest:
- Clear leaves and debris from the outdoor unit
- Ask about the grant before you commit
- Keep to regular servicing
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Book a service every year. Your manufacturer’s warranty terms may say something about servicing.
When to call us in Great Gaddesden

Reasons to give us a call include:
- Questions about where the outdoor unit can go
- An oil, LPG or gas boiler near the end of its life
- Replacing a combi boiler with a heat pump
If your home is one of the older properties near Church of St John the Baptist, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
