Before you call an engineer
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring 07833 053749.
About our air source heat pumps in Forest Hill
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home, so an add-on next to a boiler is not eligible. We’re often asked to deal with finding a place for the outdoor unit and planning and permitted development questions, across homes heated by oil, LPG or gas, hot water cylinders and radiator systems.
In a London area like Forest Hill, many homes are flats or terraces with little outside space, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and usually a cylinder, while an air-to-air system needs less space.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

Aftercare tips
Every system needs looking after, and most of it is easy. A few tips:
- Leave indoor units unobstructed
- Diary the next service
- Seal draughts where you can
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that is normal.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.
Heat pumps in Forest Hill: local notes
The Valuation Office Agency’s council tax figures put about 57% of homes across Forest Hill and its surrounding area before 1919, and the 2021 Census found about 58% of households live in flats. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. In London, outside space and the rules for flats often decide which kind of heat pump suits.
With Kingswood House about 1.6 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump. If your home is near Honor Oak Park station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

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 we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that takes a few days for most air-to-water installations, with air-to-air systems often quicker. Some blocks in Forest Hill need contractor details in advance, so tell us what your building needs.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Make sure someone can let us in at the agreed time
- Let us know where the consumer unit is
- Clear a path to the units and the space around them
Getting 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.

Common questions in Forest Hill
Can I have air conditioning in a flat in Forest Hill?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Is planning permission needed for a heat pump in Forest Hill?
There’s no single answer: the building and the outdoor unit position decide it. Central Forest Hill is a short walk from the Forest Hill Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Forest Hill, normally Southwark council).
Can I get a grant for an air-to-air heat pump?
It can, as long as the system takes over the heating completely. The £2,500 applies when it replaces the fossil-fuel heating, covers the full heating demand, is fitted by an MCS certified installer and serves a home; as an add-on to a boiler it does not qualify.
Do you cover Forest Hill?
Yes. Our engineers work in Forest Hill, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.
Do you offer emergency call-outs?
Yes. Our emergency line runs 24/7 for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
