Does the unit need a new electrical supply?
Air conditioning units require a dedicated electrical circuit. If one isn't already in place, a qualified electrician will need to install it — this is separate to the AKS installation.

📋 Note on Electrical Work
A new dedicated circuit typically costs £300–£600 and must be carried out by a qualified electrician. This is not included in your AKS installation quote — we'll flag this clearly and can recommend a trusted electrician if needed.
