- Ageing boilers that will need replacing
System by system
Hot water cylinders
Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.
Air-to-air heat pumps
Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. Hot water needs a separate source, so that has to come from elsewhere.
How we handle air source heat pumps in Crays Hill
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. The work covers air-to-air heat pumps, radiator systems and air-to-water heat pumps, and people most often call us about a boiler that’s getting old and questions about listed buildings or conservation areas.
Homes around Crays Hill usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Air source heat pumps in Crays Hill: the local picture
About 25 miles out from central London, Crays Hill is part of the South East area we work across. VOA council tax data date about 63% of homes in the Crays Hill area to the post-war years, 1945 to 1972, and the last census (2021) found about 88% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Every heat pump design starts with a room-by-room heat loss calculation. Period properties close to Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first.

Fixed-price quotes for air source heat pumps in Crays Hill
Before we fix a price, we need to know a few things. We look at:
- The size of the job
- Whether it’s a simple split or a larger system
- The electrical supply and whether a new circuit is needed
The cost depends on the system and the number of rooms or units, the access and the parts and time the job needs. You get a fixed price before any work starts, so you know where you stand.
Helping us quote
To speed up the quote, please include:
- The fuse board and where it is in the property
- A close-up of the unit’s label showing the model number
- Photos showing the indoor unit and the space around it
Quotes do not take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
For landlords and property managers
Keeping records across a portfolio is half the battle. Every visit is written up, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
Crays Hill questions
Do you cover smaller places like Crays Hill?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Do you cover Crays Hill for air source heat pumps?
Yes. We work across London and the South East from our base in East Grinstead, and Crays Hill is part of that. Get in touch with the details and we reply the same working day.
How quickly will you reply?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
How much time does a heat pump install need?
It takes from a couple of days to around a week, depending on the system and how much of the heating changes. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Which type of heat pump is right for my home?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. Both are part of what we install.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Is a heat pump permitted development?
That depends on your home and the unit’s position. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights and we look at it during the survey.
What we do, step by step
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can typically work room by room or zone by zone. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the room and the outside of the property help us plan a visit to Crays Hill.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear the space around the indoor unit, or where it will go
- Find the manual or the paperwork for the system, if you have it
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
