About our air source heat pumps in Smallfield
Air-to-water heat pumps heat your hot water through a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you will need another way to do that. We’re often asked to deal with checking eligibility for a heat pump grant and wanting to stop using oil, LPG or gas for heating, across radiator systems, air-to-air heat pumps and air-to-water heat pumps.
Cottages and older homes near Smallfield can lose heat faster, so a proper heat loss calculation matters. Sometimes insulating first makes more sense.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Homes in Smallfield and heat pumps
Listed buildings are part of the picture here: about 3 within half a mile of the centre, such as Manor Cottage (grade II). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at Tandridge council, which typically handles Smallfield. The 2021 Census found about 79% of households in detached or semi-detached houses. Houses normally have space for an outdoor unit and a hot water cylinder.
The installer applies for the Boiler Upgrade Scheme grant, and we are MCS certified. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Not far from Smallfield, a recent job of ours was on Victoria Road, Horley (RH6), about 2 miles west: installing a Daikin multi-split system serving three bedrooms and the living room.
Work in RH6 follows the same survey, fixed-price quote and written records as everywhere else we cover. That includes properties on Churchill Road, Orchard Road and Tudor Close and nearby roads.

Landmarks near Smallfield
Around Smallfield, our work takes us to homes and businesses near Oakwood School and Plough and Furrow pub, among other places. The nearest railway station is Horley station, about 2 miles west. Nearby you’ll also find Bletchingley Castle (4.5 miles north) and Effingham Park Motor Museum (2.5 miles south-east). Not far away are Hedgecourt Lake.
How the visit works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work 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 Smallfield.
- First we find out about the property, the heating you have now and what you’re hoping for.
- 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.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- 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
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about any building rules, permits or sign-in
- Mention any roof access, ladders or high-level work

Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.

Fixed-price quotes for air source heat pumps in Smallfield
The quote reflects the job in front of us. We consider:
- The condition of any existing system
- How many units are involved
- The brand, model and parts involved
Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account, and the price is fixed before any work starts.
Before you get in touch
Photos and a few facts are often enough to price a simple job. Useful things to send:
- The postcode and whether it’s a home, flat or business
- The outside wall, roof or yard where the outdoor unit sits or would go
- Wide photos of the room or the existing unit
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. For a fixed-price quote, give us a ring on 07833 053749 or send an email.
What you can do yourself, and what needs us
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. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or fill in the contact form.
Different systems, different jobs
Hot water cylinders
An older cylinder may not suit a heat pump and we tell you if it needs replacing.
Heat loss surveys
Getting the survey right avoids undersized or oversized systems and that matters for comfort and running.

Questions from Smallfield
Will you come out to Smallfield?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I get the Boiler Upgrade Scheme grant in Smallfield?
Yes, if the home and the heat pump meet the scheme’s rules: Smallfield is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, 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.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Smallfield and across Surrey. Let us know who the records should go to.
Do you look at the job first?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.

“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.”
