How much does air conditioning installation cost in Wider London?
For initial budgeting in July 2026, a straightforward single-room wall-mounted split installation may often fall around £1,800 to £3,500 including VAT in London. This is an indicative range, not a local tariff or quotation. Capacity, equipment, access, pipework, electrics, permissions and finishes determine the actual price.
London quotations can be affected by parking, congestion, restricted delivery times, scaffold or roof access and longer concealed routes. Ask for each logistical allowance to be itemised rather than accepting an unexplained London premium.
See the full UK and London installation cost guide, then prepare one brief for installation quotes.
What to discuss at the survey
Confirm ownership and consent, noise impact, external appearance and safe maintenance access before choosing equipment. Borough requirements and the specifics of the building determine the planning position.
A responsible proposal should respond to the actual building. It should not assume that every property in Wider London has the same construction, permissions or cooling load.
Before accepting a quote
- Confirm the contracting business and verify relevant credentials.
- Compare equipment, positions, routes, finishes and exclusions in writing.
- Clarify who handles permissions, electrical work, commissioning and waste.
- Understand deposits, cancellation terms, warranties and servicing.
