How it works
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, do the work, test what we have done and explain it all to you. The visit itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Getting to the outside of the property matters more than parking in a place like Hersham.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Make sure we can reach the consumer unit or fuse board
- Unlock any gate, garage or side passage we need
Getting a price
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

How we handle air source heat pumps in Hersham
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. If you’re dealing with radiators that may be too small for a heat pump and not knowing whether a grant applies, we can sort it out.
Older homes around Hersham can be draughty or have solid walls, which a heat loss calculation will show. Sometimes insulating first makes more sense.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

The Boiler Upgrade Scheme

Air source heat pumps around Hersham
About 60% of households live in detached or semi-detached houses, according to the 2021 Census. Houses normally have space for an outdoor unit and a hot water cylinder. The Hersham Village Conservation Area lies close to the centre of Hersham, within about a third of a mile. The Barley Mow Public House, listed at grade II, is one of roughly 4 protected buildings and structures in the half-mile around Hersham’s centre. Where a home is affected, the outdoor unit position is settled with Elmbridge council, normally the planning authority here before the heat pump design is finished.
The Homewood, roughly 1.4 miles south-east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. Period properties close to Church of St Peter can suit a heat pump, though insulation and any heritage protection are checked first.

Common questions in Hersham
Does the Boiler Upgrade Scheme cover homes in Hersham?
Hersham is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Do you cover smaller places like Hersham?
Yes. Hersham 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.
Do I get paperwork after the visit?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Are my radiators big enough for 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 offer emergency call-outs?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
Honest limits
It’s worth knowing the limits before booking:
- Grants for hybrid systems or replacements of low-carbon systems
- Tax advice on your own circumstances
