FAQs
Air Conditioning in Lewes: FAQs
Do you provide air conditioning across all of Lewes?
Yes, we cover the BN7 postcode area in full, including Cliffe, Southover, Landport, Nevill, Malling, Wallands.
Do I need planning permission for air conditioning?
Most domestic split system installations fall under permitted development, but conservation areas, listed buildings and flats can have specific restrictions on external unit positioning. We check the position for your property before installation.
How noisy are modern air conditioning units?
Modern outdoor condenser units are considerably quieter than older systems, though positioning still matters for noise near boundaries or bedroom windows — we advise on placement during the assessment.
How does South Downs National Park status affect building work in Lewes?
Development within the National Park is assessed with particular regard to landscape character and setting, alongside normal planning policy. Combined with the town's conservation area and listed building status, this means early advice is particularly valuable in Lewes.
