Air source heat pumps for homes and businesses in Colney Butts
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-air heat pumps, and common reasons people get in touch are deciding on the outdoor unit position and wanting to stop using oil, LPG or gas for heating.
Cottages and older homes near Colney Butts can lose heat faster, so a proper heat loss calculation matters. Sometimes insulation first is the better investment.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

How the visit works
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the room and the outside wall help us plan a job near Colney Butts.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Unlock any gate, garage or side passage we need
- Mention any managing agent or landlord rules we need to follow

Questions from Colney Butts
Do you cover smaller places like Colney Butts?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I fit a heat pump in Colney Butts without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Colney Butts is a short walk from the Square Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Colney Butts, usually Watford council).
What accreditations do you have?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are members of Checkatrade too.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
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. With air-to-air, hot water needs another source, and we explain which suits your home.
How do you keep the place clean during the work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Homes in Colney Butts and heat pumps
About 37% of homes in Colney Butts and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 51% of households live in flats, according to the 2021 Census. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows.
If your home is listed, like High Elms Manor about 3.6 miles north, listed building consent comes before any heat pump work. If you live near Watford High Street station, the survey compares air-to-water and air-to-air for your home before anything is quoted.
