A medieval river town on the Thames
Marlow grew up at a crossing of the River Thames. In the early 13th century, if not before, a planned town was laid out along High Street, West Street, Spittal Street and probably Chapel Street, with long, narrow burgage plots running back from the road. St Peter Street and the river frontage are older and less regular.
The council's character survey describes three clear phases. The medieval core was refronted in Georgian times, when fine riverside houses such as Court Garden were built. Then came Victorian and Edwardian streets east of the High Street, which grew partly after the branch railway arrived from Maidenhead via Bourne End.
The High Street ends at the Grade I listed suspension bridge by William Tierney Clark. The former Wethered Brewery buildings on the west side of the High Street were kept when the site was converted to homes.
Marlow homes and what they mean for an install
| Type of home | Typical areas | What it means for the install |
|---|---|---|
| Georgian and older townhouses | High Street, West Street, Spittal Street and St Peter Street | Conservation area, and many buildings are listed. Consent first; a hidden rear position is usually needed. |
| Victorian and Edwardian terraces and villas | East of the High Street, around Riley Road recreation ground | Inside the conservation area. Rear siting on the wall or a ground pad, away from neighbours' windows. |
| Riverside houses | Along the Thames and on Lock Island | Check flood risk first. We can raise the outdoor unit on a wall bracket or stand. |
| Houses on sloping plots | Marlow Bottom and the hills north of the town | Usually simple. Sloping plots may need a level pad or a wall bracket. |
| Flats and brewery conversions | The town centre and the former Wethered Brewery site | Freeholder or managing agent consent first. Shared plant areas and balconies are the usual spots. |
Planning and the Marlow conservation area
Planning in Marlow goes to Buckinghamshire Council, which replaced Wycombe District Council in April 2020. The old Wycombe plan still applies until the new Local Plan for Buckinghamshire is adopted. Bisham, over the bridge, is in Berkshire: planning there goes to the Royal Borough of Windsor and Maidenhead.
Buckinghamshire County Council first designated the Marlow conservation area in March 1969, and Wycombe District Council later extended and revised it. It now covers the historic core, the river frontage, Lock Island and the best of the Victorian and Edwardian streets to the east. Little Marlow has its own conservation area.
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.
Homes near the river and the Chilterns edge
Marlow has a history of flooding from the Thames. The Environment Agency recorded floods in 2003, 2012 and 2014, when 23 properties flooded. Its Marlow flood alleviation scheme was designed to reduce the impact of flooding for 287 properties, with defences and groundwater pumps at Firview Close, Gossmore Lane and Pound Lane.
If you live near the river, check your address on the government's long-term flood risk service before you book. Where there is a risk, we can mount the outdoor unit on a wall bracket or raised stand rather than at ground level.
To the north, Marlow Bottom and the wooded hills lie in the Chilterns National Landscape, called the Chilterns Area of Outstanding Natural Beauty until November 2023, and the countryside around the town is Green Belt. Neither adds a separate limit to the Class G heat pump rules.
Air conditioning for Marlow businesses
We fit and service systems for shops, restaurants, cafes, salons and offices in the town centre, and for offices and units on business parks such as Globe Park and Marlow International on Parkway. Ceiling cassettes suit open-plan 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 can look after several sites under one maintenance contract.
Parking on install day
Buckinghamshire Council runs on-street permit zones in parts of Marlow. Permits are digital through MiPermit and only work in their own zone. The old town streets are tight, so tell us when you book if your street is in a zone and we'll plan where the van parks.

Marlow questions
Do I need planning permission for air conditioning in Marlow?
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, or to Windsor and Maidenhead if you're in Bisham.
I live on the High Street or West Street. What should I check?
Whether your building is listed, and where the outdoor unit can go. These streets are in the conservation area and many buildings are listed, so you may need planning permission and listed building consent. Historic England's list shows whether a building is listed.
My house is near the Thames. Can I still have air conditioning?
Yes. Check your flood risk on the government's service first. If your home is at risk, we can fix the outdoor unit on a wall bracket or a raised stand so it sits above ground level, and route the pipes to suit.
Is Marlow Bottom in the Chilterns National Landscape?
Yes, Marlow Bottom and the hills north of the town lie inside it. For a heat pump on a house, Class G doesn't set a separate limit for National Landscapes, so the usual size, position and noise rules apply. Listed buildings and conservation areas still have their own rules.
My Victorian terrace is close to the neighbours. Will the unit be noisy?
Permitted development needs the unit to pass a noise check of 37 dB(A) at neighbours' windows, so we site it carefully. Our premium range adds quieter, more efficient units from £250. Our quiet air conditioning guide explains the options.
Do you service office air conditioning in Marlow?
Yes. We service most brands, keep F-Gas records for systems that need them, and offer maintenance contracts for businesses. If something has failed, a repair diagnostic visit is £125, deducted if you go ahead with the repair.
