How we handle air source heat pumps in Letchmore Heath
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb is not good enough. If you’re dealing with replacing a combi boiler with a heat pump and plans to switch to electric heating with a heat pump, we can help.
For a home around Letchmore Heath that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

FAQs for Letchmore Heath
Can I fit a heat pump in Letchmore Heath without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Letchmore Heath sits inside the Letchmore Heath 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 Letchmore Heath, normally Hertsmere council).
Is Letchmore Heath within the area you cover?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Is there a Boiler Upgrade Scheme grant for air-to-air?
There is a £2,500 grant for air-to-air, but only under strict conditions. It has to replace the fossil-fuel heating, meet the full heating demand, be fitted by an MCS certified installer, and be in a home.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Am I eligible for a heat pump grant?
Eligibility depends on the property and the scheme rules. In England and Wales, the scheme offers £7,500 towards an eligible air-to-water or ground source heat pump, and £2,500 towards an air-to-air heat pump only in limited cases. We check before you commit.

Looking after your system
Aftercare is straightforward, and it helps at the next service:
- Book a yearly service
- Find out the grant position at the survey
- Keep the outdoor unit clear all year
The warranty on the heat pump is the manufacturer’s, on its own terms. We explain the terms for your brand, including any servicing conditions.
Don’t cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
The process
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we clear up before we go. For a place like Letchmore Heath, the timing is set with you and the travel is our side of the planning.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Name a contact who can meet us at the agreed time
- Give us access to the outside wall, roof or yard where the outdoor unit sits
Getting a price
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.

What happens if it’s left?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions, and we explain which fits your home. Dealing with it now is usually simpler than a breakdown later.
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account and give you a fixed price before any work starts.
