Air source heat pumps in Whippendell Bottom
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. Common call-outs are for radiators that may be too small for a heat pump and comparing heat pump types, on homes heated by oil, LPG or gas, underfloor heating and air-to-air heat pumps.
In a place like Whippendell Bottom, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
The records are your 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 and it’s worth keeping safe.

Keeping the system healthy
Simple habits make a real difference. We recommend:
- Seal draughts where you can
- Let the heat pump run steadily, as set up at handover
- File the MCS certificate safely
Handover includes the controls and how to get the best from a heat pump. Steady running suits a heat pump better than switching on and off so we set the controls up with you.
Don’t cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
What a heat pump looks like in Whippendell Bottom
At about 22 miles from central London, Whippendell Bottom sits inside the area we cover across London and the South East. The 2021 Census found about 68% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Chenies Manor House lies about 3.4 miles south-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. Period properties close to Church of St Paul can suit a heat pump, though insulation and any heritage protection are checked first.

What the work involves, system by system
Outdoor unit position and planning
Permitted development conditions in England include an outdoor unit of no more than 1.5 m³ and must meet MCS 020(a) and not be used solely for cooling. It can’t be within the curtilage of a listed building.
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that following HMRC’s rules on energy-saving materials. Businesses pay the standard rate.
Landlords, agents and facilities managers
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.
