Two towns in one: Old Amersham and the Hill
Amersham has two distinct halves. Old Amersham is a medieval market town in the valley of the River Misbourne. Its High Street is lined with buildings from the 16th to the 18th centuries, and the Market Hall dates from 1682.
The Metropolitan Railway arrived in 1892, about a mile north on the ridge. A new town, Amersham-on-the-Hill, grew up around the station and in time joined up with Chesham Bois. In the 1920s and 1930s the railway's sister company built housing estates across Amersham Common, as the town became part of Metroland.
That gives the town an unusual mix of homes. The council's historic town assessment picks out the Arts and Crafts houses of Elm Close and the Weller Estate, and the modernist High and Over and the Sun Houses by Amyas Connell, which are now listed.
Amersham homes and what they mean for an install
| Type of home | Typical areas | What it means for the install |
|---|---|---|
| Period cottages and townhouses | High Street, Broadway and Church Street in Old Amersham | Conservation area, and many buildings are listed. Plan for consent first and a rear position out of view. |
| Arts and Crafts houses | Elm Close and the Weller Estate | Each is its own conservation area. Keep the outdoor unit off road-facing walls and roofs. |
| 1920s to 1930s houses and semis | Amersham-on-the-Hill and Chesham Bois | Usually straightforward. Side or rear siting with a short pipe run to the bedrooms. |
| Large detached homes | Chesham Bois, the Hill and the lanes around the town | Room for a multi-split or ducted system. Long gardens give plenty of choice for the outdoor unit. |
| Flats near the station | Amersham-on-the-Hill | Freeholder or managing agent consent first. Balconies and shared plant areas are the usual spots. |
Planning and Amersham's conservation areas
Planning in Amersham goes to Buckinghamshire Council, which replaced Chiltern District Council in April 2020. The old Chiltern plan still applies until the new Local Plan for Buckinghamshire is adopted.
The council lists four conservation areas under Amersham: Old Town, Elm Close, Shardeloes Parkland and the Weller Estate. The Old Town area was first designated in 1969 and amended in 1992. Chesham Bois, next door, has its own. Don't confuse Amersham Hill: that conservation area is in High Wycombe.
A heating-capable unit on a house is often permitted development if it meets the limits on size, position and noise. A cooling-only unit, a listed building, or a unit on a road-facing wall or roof in a conservation area needs permission. Our planning guide explains each rule.
The Chilterns, the Green Belt and Article 4
The countryside around Amersham, including the Shardeloes parkland west of the old town, is in the Chilterns National Landscape, known until November 2023 as the Chilterns Area of Outstanding Natural Beauty. The town is ringed by Green Belt. The heat pump rules in Class G don't add any separate limit for either, so the conservation area and listed building rules are what usually matter.
The Chilterns Conservation Board publishes design guidance on Chilterns brick and flint. A unit kept low and out of public view fits in best. The national planning data register lists Article 4 directions near Amersham, but the ones we found cover farmland and woodland, not homes in the town. Ask the council if you're unsure.
Air conditioning for Amersham businesses
We fit and service systems for shops, restaurants, offices, clinics and salons in both town centres. Many buildings on Old Amersham's High Street are listed, so we agree the outdoor unit position before booking a date. Ceiling cassettes suit offices with suspended ceilings; wall units suit smaller rooms.
Commercial installs are done in business hours. We service most brands, including systems another company fitted, and keep the F-Gas records your system needs.
Parking on install day
Buckinghamshire Council runs on-street permit zones in parts of Amersham. Permits are digital through MiPermit and only work in their own zone. If your street is in one, or your house sits on a narrow lane in the old town, tell us when you book so we can plan where the van parks and how the outdoor unit gets in.

Amersham questions
Do I need planning permission for air conditioning in Amersham?
Not always. A heating-capable unit on a house is often permitted development if it meets the size, position and noise limits. You need permission for a listed building, a cooling-only unit, or a unit on a road-facing wall or roof in a conservation area. Applications go to Buckinghamshire Council.
I live on the High Street in Old Amersham. What should I check?
Two things: whether your home is listed, and where the outdoor unit can go. Many High Street buildings are listed, which means planning permission and usually listed building consent. If it isn't listed, a rear position out of view from the road often works. Historic England's list shows whether a building is listed.
Is Amersham in the Chilterns National Landscape?
The countryside around the town is, including Shardeloes just west of Old Amersham. For a heat pump on a house, the Class G rules don't set a separate limit for National Landscapes. The conservation area and listed building rules usually decide whether you need to apply.
Can you fit air conditioning in an Arts and Crafts house on the Weller Estate?
Yes. The Weller Estate and Elm Close are both conservation areas, so the outdoor unit can't go on a wall or roof facing the road under permitted development. A rear or side position out of view usually works, and we keep pipe runs neat and hidden inside.
Will the outdoor unit bother my neighbours?
Permitted development needs the unit to pass a noise check of 37 dB(A) at neighbours' windows, so we work this out before fitting. Our premium range adds quieter, more efficient units from £250. Our quiet air conditioning guide explains the options.
Do you repair air conditioning in Amersham?
Yes, for homes and businesses, including systems another company fitted. A repair diagnostic visit is £125, which covers the first hour on site and is deducted if you go ahead with the repair.
