How we handle air source heat pumps in Sopwell
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems do not heat hot water, so you will need another way to do that. Typical jobs include deciding which kind of heat pump suits the home and questions about where the outdoor unit can go, on homes heated by oil, LPG or gas, radiator systems and underfloor heating.
For a house near Sopwell, space outside is rarely the problem, so heat loss, radiators and the electrics are what we check.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

System by system
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
Radiators and underfloor heating
If radiators need upsizing, the quote lists them, so the work is clear.
How it works
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes from a couple of days to around a week, depending on the system and how much of the heating changes. Tell us about any gates or steps at your property near Sopwell when you book.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Mention any managing agent or landlord rules we need to follow
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property

Let and managed properties
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side and send the records to whoever needs them.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
What air source heat pumps cannot fix
An honest diagnosis matters more to us than a booking, so here’s what air source heat pumps will not do:
- Insulation work, such as loft or cavity wall insulation
- A grant for a home that doesn’t meet the scheme rules
- Any gas work on the existing boiler
Not sure which it is? You can phone 07833 053749 or send an email and we will tell you honestly.

Sopwell: your questions answered
Is Sopwell within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Can I get the Boiler Upgrade Scheme grant in Sopwell?
Sopwell is in England, where the Boiler Upgrade Scheme runs. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.
Do I need planning permission for a heat pump?
It depends on the property and where the unit goes. 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 does an air-to-water heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales though not every home qualifies.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do you offer emergency call-outs?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
What a heat pump looks like in Sopwell
The St Albans Conservation Area lies close to the centre of Sopwell, within about a third of a mile. In the mile around Sopwell’s centre, 4 conservation areas have been designated. Listed buildings are part of the picture here: about 6 within half a mile of the centre, such as Sopwell Mill (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? Sopwell is about 19 miles from central London, well within the area we cover from our base in East Grinstead.
Older homes near St. Julian's Church may need extra checks for planning and heat loss before a heat pump is designed. Batchwood Hall, roughly 2.1 miles north-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.
