Large houses, long pipe runs, and one outdoor unit if it's designed properly
Gerrards Cross is a town of substantial detached houses on generous plots, built out after the 1906 station, alongside the older village core at Chalfont St Peter. The question here is rarely a single room: it's three, four or five, and the difference between a good installation and a poor one is whether anybody did the design work before ordering the kit.
Whole-home systems, done once
Bulstrode Way, East Common, Camp Road and the surrounding roads — large houses where the sensible answer is usually one properly designed system rather than several bolted on over the years.
- Substantial detached homes, frequently five bedrooms or more, on mature plots
- Multi-split systems serving principal bedroom, guest rooms, study and sitting room from one outdoor unit
- Long pipe runs checked against manufacturer limits — exceeded runs lose capacity and can affect warranty cover
- Mature planting and generous gardens make screening the outdoor unit straightforward
- Recent extensions and basement conversions routinely need cooling the original house never did
Period property, tighter constraints
The older village core, where the houses are smaller, closer together and considerably older than the 1906 town up the road.
- Period cottages and village-core properties, with conservation considerations in places
- Solid-wall construction more common, requiring slower and more careful core drilling
- Smaller rooms and tighter access — usually single or two-room systems rather than whole-house
- Outdoor unit siting needs more thought where gardens are compact and boundaries close
- Parking and access planned at survey, so install day isn't spent carrying kit
What we expect to find in a Gerrards Cross wall
Core drilling is where a careless installer does damage that can't be undone. Knowing what's likely behind the wall before the drill comes out is most of the job.
Cavity, interwar to modern
The Gerrards Cross standard. Cores cleanly, and gets sleeved and sealed properly so the cavity keeps working and you never see damp at the pipe run.
Solid brick, period
Chalfont St Peter's older properties. Drilled slowly and wet, internal face protected, lime mortar treated with respect.
Block and render
Later builds and the many extensions around the town. Straightforward, provided fixings go into something structural.
Basement and lower ground
Increasingly common here. Condensate can't run uphill — it needs a pump and a designed route, planned at survey rather than improvised on the day.
Gerrards Cross-specific things we check before quoting
- Pipe-run length on large plots
- Every system has a maximum line length and height difference; exceed it and you lose capacity, gain running cost and can invalidate the warranty. We measure the actual route, not the straight line.
- Basement and lower-ground rooms
- Cinema rooms, gyms and lower-ground studies are common in Gerrards Cross and are among the rooms that most need cooling. They also need proper condensate handling and ventilation thought — designed in, not bodged.
- Working alongside builders and architects
- A great deal of work here happens during extensions and refurbishments. Getting us in at first fix means pipework runs inside the fabric rather than on the outside of your new wall.
- Conservation and period fabric at Chalfont St Peter
- Checked per property before quoting, as with every job. Where consent is needed we say so up front.
What changes the price
Every quote is a fixed price for your specific home, not a range we adjust later. These are the things that move it:
- Pipe run length — the biggest variable here — large plots mean long routes, and every system has a limit
- Number of rooms running at once — how the house is actually used decides the outdoor unit size, not just the room count
- Lower-ground and basement rooms — condensate can't run uphill, so a pump and a designed route are needed
- Wall construction — period solid walls at Chalfont St Peter are slower than modern cavity
- Electrical work — whether your consumer unit has a spare way, or a new circuit is needed
- Unit choice — the Perfera, or the Stylish or Emura, which cost more
We'll tell you which of these apply at the survey — and the price we quote is the price you pay.

What people in Gerrards Cross ask us
Can one outdoor unit really serve five rooms?
Often yes, but it depends on total capacity and how many rooms you would realistically run at once. We size it for how the house is actually used rather than for a best case, and we'll tell you if two smaller systems would serve you better than one stretched one.
We're planning a basement or extension — when should we involve you?
As early as possible. Running pipework at first fix means nothing is surface-mounted afterwards, and it costs considerably less than retrofitting once the walls are finished. The full guide to planning permission →
How long can the pipework run be?
It varies by system, but every unit has a maximum line length and vertical height difference. On larger properties this genuinely matters, and it's measured at survey along the real route rather than estimated.
Will a big house need more than one outdoor unit?
Sometimes, and we'll tell you honestly if so. Splitting into two systems can be quieter, more efficient and more resilient than pushing one unit to its limit. One outdoor unit or two →
Do you work alongside our builder or architect?
Yes, and it usually produces a much better result. We'll coordinate first-fix pipework and electrical requirements directly with them.
