Headline prices rarely compare like with like. We record what each installer says is included, so you can.
Some prices include 3m of pipe, others much more. Longer runs between the indoor and outdoor unit can add hundreds.
A new circuit, isolator or filling the wall afterwards is often extra. We show who says it's included.
Some quote with VAT, some without. Warranties vary a lot, and some brands offer longer cover through approved installers.
