Air Conditioning in Listed Buildings
Listed Building Consent | Sympathetic Installation | Surrey, Sussex & South London
Installing air conditioning in a listed building is entirely achievable with the right approach — we do it regularly across Surrey, Sussex and South London. The process requires more planning, more care and more time than a standard installation, but the result is a fully working system that satisfies planning requirements and preserves the character of the building.
Do You Need Listed Building Consent?
Yes — any works to a listed building that affect its character require listed building consent from your local planning authority, regardless of whether planning permission is also needed. This includes drilling through external walls, fixing external equipment and any internal works affecting historic fabric. Carrying out works without consent is a criminal offence.
Our Listed Building Experience
We have installed in listed properties across Surrey and Sussex including Grade II listed town houses in Lewes, Georgian properties in Farnham and Godalming, Victorian commercial buildings in Reigate and Horsham, and rural listed properties in the Surrey Hills and High Weald. Every listed building installation starts with a pre-application discussion with the relevant conservation officer — we handle this process for our clients.
What Makes a Good Listed Building Installation
Outdoor unit positioning: The outdoor unit must go where it cannot be seen from public viewpoints — typically in a rear courtyard, side return or roof area. Front elevation units are almost never acceptable.
Minimal impact on historic fabric: We route pipework through the least sensitive parts of the building — through floor voids and roof spaces rather than across visible historic surfaces. Wall penetrations are kept to the minimum necessary and made good with conservation-appropriate materials.
Sympathetic materials: Fixings, sealants and making-good materials appropriate to the building’s historic fabric — not modern cement mortars on lime-mortar buildings.
Planning Authorities We Work With
We have experience with listed building consent applications to Mid Sussex District Council, Lewes District Council, Horsham District Council, Waverley Borough Council, Guildford Borough Council, Reigate & Banstead Borough Council and Brighton & Hove City Council among others.
Cost Premium
Listed building installations typically cost £400-900 more than equivalent standard installations — reflecting the design care, conservation-appropriate methodology and planning process support we provide.
