About our air source heat pumps in Garston
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss, and the quote sets it out. If the problem is no space for a hot water cylinder and deciding which kind of heat pump suits the home, we can sort it out.
If your home near Garston 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.
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.

FAQs for Garston
Can I get the Boiler Upgrade Scheme grant in Garston?
Garston is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You do not apply yourself: the MCS certified installer does, which is us.
Is Garston within the area you cover?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
How much does an air source heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales though not every home qualifies.
Will my radiators work with a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Ring 07833 053749 any time and explain the problem.
What warranty do I get?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
How we price air source heat pumps
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many units are involved
- How easy the units are to reach
- The distance and route between the indoor and outdoor units
What you pay reflects the actual work. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before we start.
Asking for a quote
When you call or email, it’s useful to have:
- Your consumer unit or fuse board
- The postcode and whether it’s a home, flat or business
- The rating plate or label on any existing unit
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, phone us on 07833 053749 or email us.
What else we do in Garston
Air source heat pumps around Garston
About 40% of homes in the Garston area date from 1945 to 1972, according to Valuation Office Agency council tax records. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Listed buildings are part of the picture here: about 3 within half a mile of the centre, such as Kytes House (grade II). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the local planning authority (typically Watford council).
Historic houses such as High Elms Manor, about 1 mile north-west, are a reminder that listed homes need consent before a heat pump goes in.
Garston is about 2 miles north of Watford, in Hertfordshire. From the centre of Garston to the outskirts, our engineers cover air source heat pumps, from a single room to a whole building.

The process
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. After that, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Because we plan from photos or a survey, a job in Garston can typically be finished in one visit.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Preparing for the visit
- Move furniture away from the wall where we will be working
- Mention any roof access, ladders or high-level work
- Mention any parking restrictions near the property

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
Do you need air source heat pumps in Garston?
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
Any of these is worth a proper look:
- Checking eligibility for a heat pump grant
- Radiators that may be too small for a heat pump
- Plans to switch to electric heating with a heat pump
Older homes near Stanborough Park Church may need extra checks for planning and heat loss before a heat pump is designed.

Before you call an engineer
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
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.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
