After we have gone
So the system stays in good health:
- Know the servicing conditions in your warranty
- Avoid switching the heat pump on and off often
- Keep the outdoor unit clear all year
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process since the grant goes through the installer.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.
Air source heat pumps in West Green
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. We are often asked to deal with no space for a hot water cylinder and questions about where the outdoor unit can go, on hot water cylinders, homes heated by oil, LPG or gas and air-to-water heat pumps.
Older homes around West Green can be draughty or have solid walls, so a proper heat loss calculation matters. Sometimes insulation first is the better investment.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

Is the heat pump grant available in West Green?
Yes, the scheme covers homes in England, including West Green, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. The installer applies, and we’re MCS certified.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Should I choose air-to-water or air-to-air?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Are you F-Gas certified?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re members of Checkatrade too.
Will I get records for the system?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Air source heat pumps in West Green: the local picture
7 conservation areas lie within a mile of central West Green. On the National Heritage List, around 10 entries fall within 0.5 miles of the middle of West Green; The George Hotel (grade II*) is one. Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Crawley council) before the heat pump design is finished. The Valuation Office Agency’s council tax figures date about 62% of homes in the West Green area to the post-war years, 1945 to 1972, and about 35% of households live in terraced houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
Period properties close to Voice of Deliverance Full Gospel Church of God can suit a heat pump, though insulation and any heritage protection are checked first. Homeowners near Crawley station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.

Landlords, agents and facilities managers
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
