About our air source heat pumps in Smithfield
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. With air-to-air, hot water has to come from something else. If the problem is deciding on the outdoor unit position and comparing heat pump types, we can help.
Homes in Smithfield are often flats and terraces, where outside space is limited, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and usually a cylinder, while air-to-air units take less room.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

What happens if it’s left?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. In London, hot spells can bring a rush of calls, so planning the work in Smithfield before summer avoids the wait.
What you pay reflects the actual work. That is why we look at the job first, from pictures or on a survey, and the price is agreed before we start.

The process
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes from a couple of days to around a week, depending on the system and how much of the heating changes. Parking bays, permits and roof or balcony access are the first things we ask about in Smithfield.
- We talk through your home, your current heating and what you want from a heat pump.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Let us know where the consumer unit is
- Let us know if the units are on a roof, a high wall or in a locked area
- Plan for pets to be kept clear during the visit
Getting a quote
Getting a quote is straightforward. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.

What else we do in Smithfield
Looking after your system
Every system needs looking after, and most of it is easy. Our tips:
- Keep to regular servicing
- Ask about the grant before you commit
- Look at insulation alongside the heat pump
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process since the grant goes through the installer.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside, so keep it clear all year.
Different systems, different jobs
Air-to-air heat pumps
A £2,500 Boiler Upgrade Scheme grant is available for air-to-air only if it replaces the fossil-fuel heating and meets the full heating demand. It also has to be fitted by an MCS certified installer, in a home.
Heat loss surveys
A heat loss survey measures how much heat each room loses on a cold day. Everything else is sized from it.
FAQs for Smithfield
Is the heat pump grant available in Smithfield?
Smithfield is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. We hold MCS certification, so the application is ours to make for you.
Will a heat pump in Smithfield need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Smithfield sits inside the Smithfield 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 don’t 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 planning department at the City of London Corporation, typically the authority for Smithfield.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
What’s the price of a heat pump installation?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.
Which type of heat pump is right for my home?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Do you work in Smithfield?
Yes. We work in Smithfield and across Greater London, within the London and South East area we cover. For a fixed-price quote, ring 07833 053749 or drop us a line.
What a heat pump looks like in Smithfield
About 32% of homes in and around Smithfield have been built since 2000, according to VOA council tax data, and the last census (2021) found about 97% of households live in flats. Better insulated, newer homes are often a good match for a heat pump. A flat may have no room for a hot water cylinder, and the freeholder normally has a say on the outdoor unit, which can tip the choice towards air-to-air. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If your home is near Farringdon station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Historic houses such as Dr Johnson's House, about 0.3 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.
