Air source heat pumps for homes and businesses in Lea Valley
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. If the problem is an oil, LPG or gas boiler near the end of its life and choosing between air-to-water and air-to-air, we can help.
Older and listed homes in villages like Lea Valley need extra care, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If a lane or gateway near Lea Valley is tight for a van, let us know and we will plan for it.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
Before we arrive
- Have the make and model of any existing unit to hand
- Keep pets out of the rooms we’re working in
- Mention any managing agent or landlord rules we need to follow

Common problems we fix in Lea Valley
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
Most people get in touch after spotting one of these:
- A boiler that is getting old
- Questions about where the outdoor unit can go
- Wanting to stop using oil, LPG or gas for heating
Shaw's Corner lies about 2.5 miles north-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
What your quote should include
- Whether they hold F-Gas company certification, not just individual qualifications
- What’s in the price and what isn’t
- Whether extra work needs your approval first
Common questions in Lea Valley
Do you cover smaller places like Lea Valley?
Yes. Lea Valley is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Is the heat pump grant available in Lea Valley?
Lea Valley is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
What does an air-to-water heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
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 and their curtilages are excluded, and listed building consent is a separate matter. We check what applies to you.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How long does a heat pump installation take?
Expect it to take a few days on site, depending on the cylinder, the radiators and the pipework involved. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
Owner checks or an engineer?
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
What happens if it’s left?
Getting the sizing wrong causes problems that are hard to fix later. Doing the survey properly from the start avoids that. Dealing with it now is typically simpler than a breakdown later.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.

Homes in Lea Valley and heat pumps
VOA council tax data date about 42% of homes in the Lea Valley area to the post-war years, 1945 to 1972, and the 2021 Census found about 62% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Houses normally have space for an outdoor unit and a hot water cylinder. About 9 listed entries lie within half a mile of central Lea Valley, Lea House (grade II) among them. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Older homes near All Saints may need extra checks for planning and heat loss before a heat pump is designed.
