The process
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. If a lane or gateway near Jacobs Well is tight for a van, let us know and we will plan for it.
- We talk through your home, your current heating and what you want from a heat pump.
- 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.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Have the make and model of any existing unit to hand
- Clear access to the fuse board
Getting a price
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from pictures or on a survey, you get a fixed price. To get going, phone 07833 053749, or email if that’s easier.
Advice
Air source heat pumps for homes and businesses in Jacobs Well
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. Eligibility depends on the property, so we confirm it before anything is agreed. If the problem is moving away from fossil-fuel heating and deciding on the outdoor unit position, we can help.
Space for an outdoor unit is rarely an issue near Jacobs Well, so the design comes down to heat loss, radiators and hot water.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Heat pumps in Jacobs Well: local notes
Valuation Office Agency council tax records date about 56% of homes across Jacobs Well and its surrounding area to the post-war years, 1945 to 1972. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks.
Guildford Castle lies about 2.3 miles south. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. Live in one of the older houses around St Peter's Church? Expect the survey to look closely at heat loss and at the building’s planning status.
Jacobs Well is about 1 mile north of Guildford, in Surrey. From the centre of Jacobs Well to the outskirts, our engineers cover air source heat pumps, from small jobs to large ones. Jacobs Well is one of 395 places in Surrey where we work for homes and businesses.
The closest recent job we can point to from Jacobs Well was on Stoughton Road, Guildford (GU2), about 1 mile south: installing a Mitsubishi Electric wall-mounted unit in the living room and a second unit in the master bedroom.

How the job changes from property to property
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
Air-to-air heat pumps
The £2,500 grant for air-to-air applies only when the system replaces the fossil-fuel heating and covers the whole home’s demand. It must be installed by an MCS certified installer and be in a home.
Questions from Jacobs Well
Can I fit a heat pump in Jacobs Well without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 7 buildings and structures within half a mile of the centre of Jacobs Well. 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 Jacobs Well, typically Guildford council) first.
Do you cover smaller places like Jacobs Well?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.
Can I get the Boiler Upgrade Scheme grant?
Not every home qualifies, so we check. There’s one grant per property, you can’t get one to replace a low-carbon system, and hybrids are excluded, among other rules.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water, and we explain which suits your home.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. At the lower temperatures a heat pump uses, radiators need more surface so we check every radiator against the room’s heat loss.

For landlords and property managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Use the settings explained at handover
- Seal draughts where you can
- Find out the grant position at the survey
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.
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.”
