Morden and surrounding areas
Premises in Morden are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.
We cover every Morden postcode, including BH20 and SM4. Neighbouring towns we cover include Mitcham, Wimbledon and Carshalton. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

Points to plan for in Morden
Filters
Filters must be changed regularly to keep air flow and air quality up.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Summer bypass
A bypass avoids warming incoming air in summer.
Conservation areas
Historic streets and listed buildings in and around Morden are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
