Air source heat pumps in Warner's End
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. If the problem is working out where a cylinder could go and checking emitters for a heat pump, we can sort it out.
If your home near Warner's End has no mains gas, the grant can be bigger. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027, for an air source or ground source heat pump.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Fixed-price quotes for air source heat pumps in Warner's End
Typical ranges are on our prices page, but every job is priced on its own. The quote depends on:
- Which make and model is being fitted or worked on
- The size of the job
- Whether we need access equipment for high-level work
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account and give you a fixed price before any work starts.
What we need to know
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- A photo of the consumer unit with the cover closed
- Your installation or service records
- Photos showing the indoor unit and the space around it
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price so you know the cost before we begin.
What owners can safely do
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Some faults have simple causes you can check first: 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 us on 07833 053749 or drop us a line.
Warner's End questions
Is Warner's End within the area you cover?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
Is the heat pump grant available in Warner's End?
Warner's End is in England, where the Boiler Upgrade Scheme runs. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
How long does a heat pump installation take?
Expect it to take several days for an air-to-water system with a new cylinder, less for an air-to-air system. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. Both are part of what we install.
How it works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the visit to Warner's End from the survey or your photos.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Mention any parking restrictions near the property
- Mention any roof access, ladders or high-level work
- Keep pets and children away from the work area

Air source heat pumps around Warner's End
Warner's End is about 25 miles from central London, well within the area we cover from our base in East Grinstead. Valuation Office Agency council tax records date about 69% of homes in the Warner's End area to the post-war years, 1945 to 1972, and the last census (2021) found about 47% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
A heat loss calculation decides the size of heat pump your home needs. Live in one of the older houses around St Alban's Church? Expect the survey to look closely at heat loss and at the building’s planning status.
