Your questions about air source heat pumps in Henfield
Does the Boiler Upgrade Scheme cover homes in Henfield?
Yes, if the home and the heat pump meet the scheme’s rules: Henfield is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.
Can I fit a heat pump in Henfield without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Henfield sits inside the Henfield 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 Henfield, normally Horsham council).
Who is responsible for leak checks?
Responsibility is shared between the operator, typically 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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How long does a heat pump installation take?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the work so you are without heating for as little time as possible and agreed before work begins.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
About our air source heat pumps in Henfield
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb is not good enough. If you are dealing with working out where a cylinder could go and an oil, LPG or gas boiler near the end of its life, we can sort it out.
If your home near Henfield has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme, for an air source or ground source heat pump.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What we’re called out for in Henfield
Many enquiries start with a question about the Boiler Upgrade Scheme. Whether you can get the grant depends on your home and the scheme conditions and we confirm it before you go ahead.
It’s time to call us if you are dealing with:
- Wanting to stop using oil, LPG or gas for heating
- Ageing boilers that will need replacing
- Choosing between air-to-water and air-to-air
Period properties close to St Peter's Church can suit a heat pump, though insulation and any heritage protection are checked first.

How the visit works
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Because we plan from pictures or a survey, a job in Henfield can usually be finished in one visit.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- After commissioning, you get the MCS certificate and a handover.
How to prepare
- Make sure we can reach the outdoor unit, or where it will go
- Dig out any previous service or F-Gas records
- Clear the space around the indoor unit, or where it will go
Get a fixed-price quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.
Advice
Fixed-price quotes for air source heat pumps in Henfield
We quote each job individually. These are the things that affect it:
- What state the existing equipment is in
- Whether it’s a one-off job or part of a maintenance contract
- How far the pipework has to run, and where
Every job is different, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all play a part.
Before you get in touch
A few details help us quote accurately. With your enquiry, please include:
- Wide photos of the room or the existing unit
- The postcode and whether it’s a home, flat or business

How the job changes from property to property
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, so radiator sizes matter.
Radiators and underfloor heating
If radiators need upsizing, the quote lists them, so you know the full scope.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
