Air source heat pumps in Aldenham, done properly
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes, and the quote sets it out. If the problem is moving away from fossil-fuel heating and checking whether planning permission is needed, we can sort it out.
If your home in or near Aldenham is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Homes in Aldenham and heat pumps
VOA council tax data date about 52% of homes across Aldenham and its surrounding area to the post-war years, 1945 to 1972. For homes of that age, the survey checks the insulation, the radiators and the hot water setup.
High Elms Manor, roughly 2.5 miles north-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

What air source heat pumps cannot fix
Air source heat pumps cannot fix everything, and we’d rather say so up front. It will not put right:
- Improving the building’s insulation
- Getting planning permission or listed building consent on your behalf
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If you’re not sure, just call us on 07833 053749, or email if that’s easier and we’ll give you a straight answer before booking.

Safe owner checks
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749.
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
FAQs for Aldenham
Is a heat pump in Aldenham permitted development?
The answer turns on the property and where the outdoor unit would sit. Central Aldenham is a short walk from the Aldenham Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Hertsmere council, which is typically the planning authority for Aldenham.
Can I get the Boiler Upgrade Scheme grant in Aldenham?
Yes, if the home and the heat pump meet the scheme’s rules: Aldenham is in England, where it applies. 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. We hold MCS certification, so the application is ours to make for you.
Does servicing affect my warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Which accreditations do you hold?
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.
Are my radiators big enough for a heat pump?
It varies from room to room. We check them all during the survey, so the quote covers any changes.
