Air source heat pumps in Five Oaks
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. If the problem is checking whether planning permission is needed and questions about the Boiler Upgrade Scheme, we can sort it out.
If your home in or near Five Oaks is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

How we price air source heat pumps
Your quote is based on your property. We consider:
- What we find on the survey or diagnosis
- The brand, model and parts involved
- How easy the units are to reach
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before any work starts.
Asking for a quote
When you contact us, these details help:
- A short video of any fault, such as a noise or a flashing light
- A close-up of the unit’s label showing the model number
- Your installation or service records
For air source heat pumps in Five Oaks, phone us on 07833 053749 or use the quote form. Let us know the type of property and what you need, plus some pictures if they’re to hand. Enquiries get a reply the same working day.
What you can do yourself, and what needs us
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call 07833 053749.
What we do, step by step
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes, and we tidy up before we leave. Pictures of the space and where the outdoor unit could go let us plan the work in Five Oaks.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Dig out any previous service or F-Gas records

Questions from Five Oaks
Is a heat pump in Five Oaks permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Five Oaks holds about 4 listed buildings and structures. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with the planning department at Horsham council, typically the authority for Five Oaks.
Is the heat pump grant available in Five Oaks?
Yes, if the home and the heat pump meet the scheme’s rules: Five Oaks is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How quickly will you reply?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How long will it take to install a heat pump?
As a guide, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. We plan the work so you are without heating for as little time as possible, and we explain it in advance.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
What a heat pump looks like in Five Oaks
About 81% of households live in detached or semi-detached houses, according to Census 2021 figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Grant applications go through the MCS certified installer, so that part is handled for you. A heat loss calculation decides the size of heat pump your home needs.

After we’ve gone
Systems last better with the right care. We suggest:
- Leave space around the outdoor unit
- File the MCS certificate safely
- Keep to regular servicing
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Book a service every year. Your manufacturer’s warranty terms may say something about servicing.
