What affects the cost of air source heat pumps
Every job gets its own quote. This is what makes a difference:
- Which make and model is being fitted or worked on
- What electrical work the job needs
- Access, including height, roofs and ladders
What you pay reflects the actual work. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before work begins.
Helping us quote
When you contact us, these details help:
- A close-up of the unit’s label showing the model number
- Where the property is and what kind of building it is
- Your installation or service records
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Air source heat pumps in Watt's Cross, done properly
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it does not apply to businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. If the problem is questions about listed buildings or conservation areas and choosing between air-to-water and air-to-air, we can sort it out.
Older and listed homes in villages like Watt's Cross need extra care, and permitted development doesn’t cover listed buildings, so we check consent first.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

Air source heat pumps in Watt's Cross: the local picture
About 43% of homes in the Watt's Cross area date from 1945 to 1972, according to VOA council tax data, and the 2021 Census found about 82% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Houses usually have space for an outdoor unit and a hot water cylinder. 2 conservation areas lie within a mile of central Watt's Cross. The Old House, listed at grade II*, is one of roughly 9 protected buildings and structures in the half-mile around Watt's Cross’s centre. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at Tonbridge and Malling council, which typically handles Watt's Cross.
Period properties close to Parish Church of St John can suit a heat pump, though insulation and any heritage protection are checked first.

Common questions in Watt's Cross
Will you come out to Watt's Cross?
Yes. Watt's Cross is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in Watt's Cross?
Watt's Cross is covered, as the scheme runs across England and Wales. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we are MCS certified.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
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 systems are priced after a survey, with the VAT confirmed on your quote.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
How quickly will you reply?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
The process
Protection comes first: 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. The work on site takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we tidy up before we leave. Photos of the room and the outside of the property help us plan a visit to Watt's Cross.

Advice
When to call us in Watt's Cross
People also ask about air-to-air heat pumps because they heat and cool. They warm rooms directly through indoor units, and can cool them when it’s hot. Whether a grant applies depends on the scheme conditions.
Reasons to give us a call include:
- Questions about where the outdoor unit can go
- Replacing a combi boiler with a heat pump
- Deciding which kind of heat pump suits the home
If your home is listed, like Ightham Mote about 3 miles north-east, listed building consent comes before any heat pump work.
What to look for in a quote
- Which brand and model they’re proposing, and why
- Whose warranty applies, and on what terms
- If the quote is based on a survey, photos or a diagnosis

What else we do in Watt's Cross
Why it’s worth doing now in Watt's Cross
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Surveying and designing in advance means the system is sized right and any grant is applied for before you need the heat. Planning ahead for a job in Watt's Cross means we can bring everything needed.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are unsure, give us a ring on 07833 053749 or fill in the contact form and we’ll give you an honest view and a fixed price.
