Air source heat pumps in Cockfosters, done properly
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. The work covers homes heated by oil, LPG or gas, radiator systems and air-to-water heat pumps, and common reasons people get in touch are not knowing whether a grant applies and choosing between air-to-water and air-to-air.
For flats in Cockfosters, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, and we check before designing.
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 each visit is recorded.

What the work involves, system by system
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.
The Boiler Upgrade Scheme
Only one grant is available per property, and it can’t replace a low-carbon system, and hybrid systems are not eligible.
Honest limits
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Planning approval where permitted development does not apply
- Improving the building’s insulation
- Disconnecting or servicing a gas boiler
If in doubt, call us on 07833 053749, or email if that’s easier and we’ll say what we think.

What a heat pump looks like in Cockfosters
Valuation Office Agency council tax records show about 30% of homes in and around Cockfosters date from 1919 to 1939, and the last census (2021) found about 60% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Live in one of the older houses around Christ Church? Expect the survey to look closely at heat loss and at the building’s planning status. Wyllyotts Manor, roughly 3.4 miles north-west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Owner checks or an engineer?
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What we do, step by step
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes from a couple of days to around a week, depending on the system and how much of the heating changes. The more we can see beforehand, the smoother the visit to Cockfosters will be.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- 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 we can reach the outdoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board
- Keep pets and children away from the work area

Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.

Questions from Cockfosters
Does the Boiler Upgrade Scheme cover homes in Cockfosters?
Cockfosters is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You do not apply yourself: the MCS certified installer does, which is us.
Can I fit a heat pump in Cockfosters without planning permission?
The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Monken Hadley Conservation Area, close to central Cockfosters. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the planning department at Enfield council, usually the authority for Cockfosters.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How long does a heat pump installation take?
As a guide, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the work so you are without heating for as little time as possible and agreed before we start.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
From one of our customers
“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.”
