Do you need air source heat pumps in Northaw?
Many enquiries start with a question about the Boiler Upgrade Scheme. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.
These are the situations we see most often:
- Finding a place for the outdoor unit
- Questions about the Boiler Upgrade Scheme
- No space for a hot water cylinder
Wyllyotts Manor, roughly 2.1 miles west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Air source heat pumps for homes and businesses in Northaw
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps, and the jobs we see most are finding a place for the outdoor unit and working out whether radiators need upsizing.
Homes around Northaw usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Owner checks or an engineer?
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Aftercare tips
After the visit, a few habits help:
- Keep radiators clear
- Clear leaves and debris from the outdoor unit
- Avoid switching the heat pump on and off often
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts, and we will explain the settings for your home.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
Northaw questions
Do you cover smaller places like Northaw?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Northaw?
Yes, the scheme covers homes in England, including Northaw, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
How long will it take to install a heat pump?
As a guide, it 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 agreed before we start.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do I need planning permission for a heat pump?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings are excluded, and listed building consent is separate. We check what applies to you.
Should I choose air-to-water or air-to-air?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. We install both types.
What’s the price of a heat pump installation?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.

Heat pumps in Northaw: local notes
Northaw’s centre is no more than about a third of a mile from the Northaw Village Conservation Area. About 15 listed entries lie within half a mile of central Northaw, Parish Church of St Thomas a Becket (grade II*) among them. Where a home is affected, the outdoor unit position is settled with the local planning authority (normally Welwyn Hatfield council) before the heat pump design is finished. Valuation Office Agency council tax records date about 44% of homes in and around Northaw to the post-war years, 1945 to 1972, and about 84% of households live in detached or semi-detached houses, according to the last census (2021). Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
If your home is one of the older properties near Parish Church of St Thomas A Becket, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
