Delivery

Delivery from London. This is a larger kit (4 pallets), so we quote delivery to your postcode. No VAT to add. The price shown is the price you pay.

SIP panels are 2.44 m long and travel on long pallets. The carrier delivers kerbside with no tail-lift, so you need a forklift or enough people to unload at the delivery address. Highlands, islands, Northern Ireland and larger kits: ask for a quote. See delivery zones. We’ll confirm a delivery date when you order.
