Air source heat pumps in Warnham, done properly
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Guesswork leads to systems that are too big or too small. The work covers radiator systems, air-to-water heat pumps and underfloor heating, and common reasons people get in touch are wanting to stop using oil, LPG or gas for heating and comparing heat pump types.
For a home around Warnham 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, on top of the £7,500.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Air source heat pumps around Warnham
About 30 miles out from central London, Warnham is part of the South East area we work across.
Every heat pump design starts with a room-by-room heat loss calculation. Older homes near The Parish Church of St Margaret may need extra checks for planning and heat loss before a heat pump is designed.

Around Warnham
Typical jobs here are in properties near Warnham Park, The Greets Inn and Greenway Academy, among other places. For rail, the closest station is Warnham station, about 1 mile east. Well-known places in the area include Horsham Hospital (1.8 miles south-east) and Christs Hospital School Museum (3.2 miles south). Open spaces near Warnham include Warnham LNR and Vann Lake.
The process
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the trip to Warnham around you.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Before we arrive
- Tell us about parking and loading
- Clear the space around the indoor unit, or where it will go
- Tell us about access, such as roof hatches, high walls or locked plant areas
How to get a quote
For a fixed-price quote, ring 07833 053749 or send an email with the address and a few details about the rooms or units involved. Photos help a lot. We reply to enquiries the same working day.

Keeping the system healthy
Looking after it is simple, and it helps at the next service:
- Keep radiators clear
- Keep up with insulation and draught-proofing
- Store the MCS certificate and warranty documents together
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. You might see steam or hear the unit change note, and that is normal.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
System by system
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
Air-to-air heat pumps
An air-to-air system heats rooms directly and can also provide cooling. They do not heat hot water so you’ll need another way to heat it.

Warnham: your questions answered
Do you cover smaller places like Warnham?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I need planning permission for a heat pump in Warnham?
It depends on the property. The centre of Warnham is in the Warnham 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 planning department at Horsham council, typically the authority for Warnham.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Do I get paperwork after the visit?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Will you work on another installer’s system?
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.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
