Sawston is a village of two halves, and the survey starts by asking which half you are in
Sawston has a conservation area, designated by South Cambridgeshire District Council in 2007, and it is focused on the historic High Street spine. That stretch carries a serious concentration of listed buildings: houses at 26, 54, 61, 82 and 84 High Street among others, entries on Mill Lane and Orchard Lane, five listed pubs including the Grade II Queen’s Head Inn, and two Grade I buildings in Sawston Hall and St Mary’s Church. Even the village’s industrial past is listed, with the Great Eastern Drying Shed at the old Hutchings and Hardings tannery site holding Grade II status.
An outdoor condensing unit is an external alteration, which is exactly the kind of thing that attracts attention in those settings. In broad terms, permitted development rights for outdoor units are normally restricted in conservation areas, and on a listed building you should expect to need consent whatever the unit looks like. On the High Street and the lanes off it, we design for a discreet rear position, low down, out of view from the street, with pipework routed internally or in properly finished trunking. Where consent is needed we say so before you have committed to anything. The planning authority here is South Cambridgeshire District Council, working through Greater Cambridge Shared Planning, and we would rather you check with them than fit a unit that has to come off later.
The other half of Sawston is the easier half. The large post war estates to the north west and south of the village sit outside the conservation area, and so does the newest housing on the southern edge where development has run Sawston into Pampisford. On that stock an outdoor unit is usually a straightforward siting conversation rather than a design exercise.
Why Sawston homes overheat
Loft conversions. Sawston is a commuter village, seven miles south of Cambridge with Whittlesford Parkway station about two miles away, and a lot of families have gone up rather than moved. A converted loft has the roof directly overhead, insulation designed to keep heat in through winter, and small windows. By mid afternoon in July it is the hottest room in the house and no amount of window opening fixes it.
Glazed rear extensions. The older houses around the village centre have picked up modern glazed extensions over the years, and a big area of south or west facing glass gains heat far faster than ventilation can remove it.
Home offices. Plenty of back bedrooms in the post war estates now hold a desk, a computer and a person for eight hours a day. That is a constant heat load in a small room the house was never designed around.
New build on the southern edge. Modern housing near Unity Campus and the Pampisford boundary is well insulated and airtight, which is exactly what makes a south facing bedroom uncomfortable through a warm spell.
These systems heat as well as cool, and that is half the point
Modern split air conditioning is an air to air heat pump. Run one way it cools. Running in reverse, it heats efficiently, producing several units of heat for every unit of electricity used.
That matters in Sawston’s older stock. A solid walled cottage off the High Street, or an industrial conversion with high ceilings and long pipe runs, is hard to heat evenly with radiators alone, and extending a wet heating system through a timber framed listed building is disruptive work. An air to air unit puts controllable heat into one room without touching the pipework, and then earns its keep again in summer. A loft room or a garden office gets solved once, with one machine, instead of a fan in July and a plug-in heater in February.
The systems we install around Sawston
Wall mounted single splits. One indoor unit, one outdoor unit. The standard answer for a bedroom, a loft conversion or a home office, and the least disruptive install of the lot.
Multi-split systems. From two to five indoor units can run off a single outdoor condenser. The right call where only one outdoor position is acceptable, which is often the case in the conservation area and in terraced plots with small rear yards.
Ducted and concealed units. Concealed in a ceiling void or cupboard, the indoor unit delivers air out through grilles. More work and more money, and worth it in a high specification refurbishment where a visible wall unit is not wanted.
Floor mounted and low wall units. Handy under a window, and often the neatest answer in a room with sloping ceilings, which describes most loft conversions.
We install Daikin, Mitsubishi Electric, Samsung, LG and Fujitsu, and we choose from those ranges after the survey, based on the heat gain, the pipe route and how quiet the indoor unit needs to be.
We size room by room using a heat gain calculation, never from floor area alone. Go too big and the unit short cycles, struggles with humidity and runs louder than it needs to. That biggest kilowatt figure on the cheapest quote is usually pointing you at the wrong machine.
What the installation actually involves
A single split in a straightforward Sawston property is a day for two engineers. A multi-split covering three or four rooms generally runs to two or three days.
Indoor and outdoor positions get agreed before anything comes off the van, and the pipe route is then core drilled. The refrigerant pipework, control cable and condensate drain all run together, which is why the route deserves the most careful planning. The outdoor unit goes on brackets or a ground frame with anti-vibration mounts, then the system is pressure tested with nitrogen, evacuated under vacuum and commissioned. Electrical work is carried out by qualified electricians and certificated as part of the job. Before we leave you get a proper walk through of the controls, including the heating mode, which most owners underuse in the first winter.
Condensate deserves its own paragraph in a village like this. An indoor unit in cooling mode produces water, and it must run with a continuous fall to a suitable drain, or through a condensate pump where gravity cannot do the job. Sawston sits low, on a former flood plain by the Cam, and the ground here tends towards the damp, so simply dribbling condensate out of a wall and letting it soak away is poor practice. We terminate it into proper drainage and lag whatever needs lagging.
The properties where the job gets more interesting
The High Street and the lanes off it. Listed buildings, timber frames, solid walls and conservation area status all at once. Unit siting is a design exercise, drilling through old fabric needs care, and consent questions come before quotes. A single carefully placed outdoor unit feeding a multi-split is usually the answer.
The old industrial buildings. Sawston grew on a paper mill and two tanneries, all sited here for the clean local water, and some of that fabric survives as listed buildings and conversions. High ceilings and big open volumes mean the heat gain calculation matters more than usual, and long internal pipe runs need planning.
The post war estates to the north west and south. The bulk of the village’s housing and the bulk of the work. Cavity walls and sensible layouts make these the quickest installs we do, typically driven by a loft conversion, a south facing bedroom or a home office.
The newest housing towards Pampisford and Unity Campus. Modern, airtight and quick to overheat. Straightforward installs, and the developer’s electrical layout usually makes the wiring simple.
What it costs
We do not publish a fixed price, because a single split in a modern estate bedroom and a multi-split threaded through a listed building on the High Street are different jobs entirely.
The price moves with the number of indoor units, the length and difficulty of the pipe route, wall brackets versus a ground frame, whether a condensate pump is needed, and the making good. Ducted systems cost more because most of the work is hidden above the ceiling.
What you get is an itemised written quote after a survey, with the 0% VAT where the installation qualifies position stated on it while the relief applies to residential supply and install under VAT Notice 708/6, currently to 31 March 2027.
Hard water, servicing and the warranty
Sawston’s mains water comes from Cambridge Water, not Anglian Water, and Cambridge Water’s published figure for the Cambridge Rural supply zone (Z3), which covers Sawston, is 317.9 mg/l of calcium carbonate. That is over the very hard threshold. Air conditioning does not scale up the way a boiler does, but condensate trays, drains and any water-side kit still live in that environment, and the same survey visit can look at scale protection for your heating system while we are there.
The system itself needs an annual service: filters cleaned, coils checked, condensate route confirmed clear, refrigerant charge verified. Many manufacturers make servicing a condition of the equipment warranty, depending on the brand and its terms, so it is worth reading what yours requires. Refrigerant is handled under F-Gas rules from installation through to eventual decommissioning and recovery, which is also why we can remove an old system properly instead of venting it.

Frequently asked questions
Do I need planning permission for air conditioning in Sawston? Often not on the post war estates, where a domestic outdoor unit meeting the permitted development conditions is usually fine. The conservation area along the High Street is different, because those rights are normally restricted there, and listed buildings need consent. We check your address with Greater Cambridge Shared Planning before designing anything.
Does my installation qualify for 0% VAT? Yes. Residential supply and installation of qualifying energy saving materials, which includes air conditioning of this type, is zero rated under HMRC VAT Notice 708/6, currently until 31 March 2027. It appears on the written quote.
Will it heat my room in winter? Yes. These are air to air heat pumps at their core, running in reverse to heat the house efficiently. In a Sawston loft conversion or garden office it can be the main heat source, not just a summer machine.
How many rooms can one outdoor unit serve? A multi-split typically runs two to five indoor units from one condenser, which suits terraced plots and conservation area properties where a single discreet outdoor position is all that is realistic.
Where does the condensate go? Into proper drainage with a continuous fall, or through a small condensate pump where gravity will not work. Sawston sits low by the Cam and the ground tends towards the damp, so we do not just drip it out of the wall.
Will you look after a system another company fitted? Yes. We service and repair other installers’ systems, and if something has been fitted badly we will tell you plainly and put it right.
