Air source heat pumps for homes and businesses in Ditton Hill
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. The work covers hot water cylinders, air-to-water heat pumps and underfloor heating, and the jobs we see most are questions about the Boiler Upgrade Scheme and working out whether radiators need upsizing.
In a flat in Ditton Hill, the lease and the freeholder normally decide where a heat pump can go. Permitted development limits are different for flats, so we check the position before we design.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

How we price air source heat pumps
We quote each job individually. These are the things that affect it:
- Whether it’s a one-off job or part of a maintenance contract
- How far the pipework has to run, and where
- What electrical work the job needs
The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before work begins.
What we need to know
Good pictures often save a visit. The most useful are:
- The rating plate or label on any existing unit
- Where the outdoor unit is, or where you’d like it
- Your installation or service records
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.
Homes in Ditton Hill and heat pumps
In London, outside space and the rules for flats often decide which kind of heat pump suits.
Period properties close to Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first. Hampton Court Palace, roughly 2 miles north-west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

What we do, step by step
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Some blocks in Ditton Hill need contractor details in advance, so tell us what your building needs.
- First we find out about the property, the heating you have now and what you are hoping for.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear access to the fuse board
- Tell us about parking and loading
Ask for a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.

Your questions about air source heat pumps in Ditton Hill
Do I need permission to put air conditioning in my flat in Ditton Hill?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do I need planning permission for a heat pump in Ditton Hill?
It comes down to the building and the spot chosen for the outdoor unit. The Long Ditton Conservation Area is close to the centre of Ditton Hill. 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 Ditton Hill, normally Elmbridge council) first.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Does servicing affect my warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.
Is the equipment covered by a warranty?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Ring 07833 053749 any time and explain the problem.

Different systems, different jobs
VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
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.”
