FAQs for Little Gaddesden
Is Little Gaddesden within the area you cover?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is a heat pump in Little Gaddesden permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Central Little Gaddesden is a short walk from the Little Gaddesden Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Dacorum council, which is typically the planning authority for Little Gaddesden.
How long does a heat pump installation take?
An installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The survey lets us set a firm programme, and you can give us a ring on 07833 053749 or send an email to book it.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
How much VAT is charged on a heat pump in a home?
Not on a home installation at the moment: HMRC zero-rates heat pumps installed in residential accommodation until 31 March 2027, and 5% applies after that. Businesses and hotels pay the standard rate, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice.
Can we book visits on a schedule?
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.
Will my home qualify for the Boiler Upgrade Scheme?
Quite possibly. In England and Wales it pays £7,500 for an eligible air-to-water or ground source heat pump, and £2,500 for air-to-air under tighter rules. Until March 2027 there’s an extra £1,500 for air source or ground source heat pumps in homes on oil or LPG with no mains gas. We check your home against the rules at the survey.
Air source heat pumps in Little Gaddesden
Every installation starts with a 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. Guesswork leads to systems that are too big or too small. Typical jobs include finding a place for the outdoor unit and an oil, LPG or gas boiler near the end of its life, on hot water cylinders, radiator systems and air-to-water heat pumps.
For a home around Little Gaddesden that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Before you call an engineer
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
Looking after your system
Once we’ve finished, these simple steps help:
- Diary the next service
- Don’t block radiators or indoor units with furniture
- Store the MCS certificate and warranty documents together
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
