Air source heat pumps for homes and businesses in Long Marston
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes, and the quote sets it out. Typical jobs include plans to switch to electric heating with a heat pump and working out whether radiators need upsizing, across hot water cylinders, air-to-water heat pumps and air-to-air heat pumps.
For a home around Long Marston that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Aftercare is simple, and most of it is in the manual: 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.

Other services in Long Marston
Do you need air source heat pumps in Long Marston?
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. 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.
It’s time to call us if you’re dealing with:
- Working out where a cylinder could go
- Deciding which kind of heat pump suits the home
- Not knowing whether a grant applies
Period properties close to Church of All Saints (Church of England) can suit a heat pump, though insulation and any heritage protection are checked first.

How the job changes from property to property
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
When it’s something else
Some problems need a different service or another trade:
- Tax rulings, which only HMRC can give
- Planning approval where permitted development does not apply
- Improving the building’s insulation
If in doubt, call us on 07833 053749 or fill in the contact form and we will say what we think before booking.

Common questions in Long Marston
Is Long Marston within the area you cover?
Yes. Long Marston is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I fit a heat pump in Long Marston without planning permission?
It depends on the property. Central Long Marston sits inside the Long Marston Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Dacorum council, usually the authority for Long Marston.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
How much time does a heat pump install need?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the work so you are without heating for as little time as possible, and we explain it in advance.
How quickly will you reply?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
The process
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Visits to Long Marston are agreed with you in advance and planned so the job can be finished in one trip where possible.

Advice
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.”
