Air source heat pumps for homes and businesses in Cottered
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you’ll need another way to do that. If you are dealing with not knowing whether a grant applies and radiators that may be too small for a heat pump, we can help.
For a home around Cottered that’s 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.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

How the visit works
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. Pictures of the space and where the outdoor unit could go let us plan the work in Cottered.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Unlock any gate, garage or side passage we need
- Find the manual or the paperwork for the system, if you have it
- Keep pets out of the rooms we’re working in
Get a fixed-price quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- A grant for a home that does not meet the scheme rules
- Tax advice on your own circumstances
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If you are not sure, just ring us on 07833 053749 or fill in the contact form and we’ll give you a straight answer before booking.

Heat pumps in Cottered: local notes
About 35% of homes across Cottered and its surrounding area have been built since 2000, according to the Valuation Office Agency’s council tax figures, and about 69% of households live in detached or semi-detached houses, according to Census 2021 figures. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Houses normally have space for an outdoor unit and a hot water cylinder.
Every heat pump design starts with a room-by-room heat loss calculation. Older homes near Parish Church of St John the Baptist may need extra checks for planning and heat loss before a heat pump is designed.

After we have gone
Aftercare is straightforward, and it helps at the next service:
- Ask about the grant before you commit
- Avoid switching the heat pump on and off often
- Leave space around the outdoor unit
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Heat pumps prefer steady, low-temperature running as explained at handover.
FAQs for Cottered
Do you cover smaller places like Cottered?
Yes. Cottered is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can I fit a heat pump in Cottered without planning permission?
The answer turns on the property and where the outdoor unit would sit. The Cottered Conservation Area is close to the centre of Cottered. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Cottered, usually East Hertfordshire council) first.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Cottered and across Hertfordshire. Let us know who the records should go to.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
What VAT do I pay on a heat pump?
Heat pumps in homes carry 0% VAT until 31 March 2027, with 5% from 1 April 2027. Businesses pay the standard rate. This is general information, not tax advice.
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.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
