Air source heat pumps for homes and businesses in Great Amwell
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. If you are dealing with moving away from fossil-fuel heating and choosing between air-to-water and air-to-air, we can sort it out.
Space for an outdoor unit is rarely an issue near Great Amwell, so the design focuses on heat loss and radiators.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

What we do, step by step
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes a few days for most air-to-water installations, with air-to-air systems often quicker. Somewhere like Great Amwell, it helps to know about lanes, gates and where to park.
- 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.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit

Questions from Great Amwell
Is a heat pump in Great Amwell permitted development?
That depends on the building and where the outdoor unit goes. Central Great Amwell is a short walk from the Great Amwell 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 East Hertfordshire council, which is typically the planning authority for Great Amwell.
Can I get the Boiler Upgrade Scheme grant in Great Amwell?
Great Amwell is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we are MCS certified.
Do I need to service the system to keep the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.

What else we do in Great Amwell
Why deal with it now?
A sudden boiler failure rarely leaves room to plan a heat pump properly. Surveying and designing in advance means the system is sized right and any grant is applied for while the old heating still works. Dealing with it now is usually simpler than a breakdown later.
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. The price is fixed before we start, and the quote sets out the VAT.
