Air source heat pumps in North Lee, done properly
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. We check each radiator against the room’s heat loss, and the quote sets it out. The work covers air-to-water heat pumps, radiator systems and homes heated by oil, LPG or gas, and the jobs we see most are choosing between air-to-water and air-to-air and finding a place for the outdoor unit.
Older and listed homes in villages like North Lee need extra care, and permitted development does not cover listed buildings, so consent comes first.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Honest limits
Air source heat pumps cannot fix everything, and we’d rather say so up front. It will not put right:
- Grants for hybrid systems or replacements of low-carbon systems
- Getting planning permission or listed building consent on your behalf
- Any gas work on the existing boiler

What else we do in North Lee
Safe owner checks
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
Air source heat pumps around North Lee
The last census (2021) found about 52% of households in terraced houses. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. North Lee is about 36 miles from central London, well within the area we cover from our base in East Grinstead.
Period properties close to Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first. A heat loss calculation decides the size of heat pump your home needs.

Managing agents and facilities teams in North Lee
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side and send the records to whoever needs them.
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we will come back with a fixed-price quote.
The process
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the room and the outside of the property help us plan a visit to North Lee.
- It starts with a conversation about the home, the existing heating and your plans.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know where we can park and unload
- Keep pets and children away from the work area
Ask for a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
Questions from North Lee
Can I get the Boiler Upgrade Scheme grant in North Lee?
North Lee is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Do you cover North Lee for air source heat pumps?
Yes. North Lee is one of the places we cover. Get in touch with the details and we reply the same working day.
Which type of heat pump is right for my home?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Who is responsible for 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.
Will skipping a service affect the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
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. How much of the heating changes decides most of the time, and we confirm the timing with your quote.
