Deliveries are usually made by courier between the hours of 8am and 6pm Monday to Friday.
Delivery will vary depending on the product, delivery lead times are stated on each individual product listing on our website (below item description and also on the 'Specification' tab).
When your order is being dispatched you will receive a dispatch email with delivery tracking where possible.
Please note that couriers UK wide are only contracted/insured to deliver kerb/roadside therefore you may have to bring the radiator(s) into your property yourself and for large or heavy items you may require assistance.
IMPORTANT (non UK mainland) - We are currently unable to ship goods outside of the UK or to Northern Ireland (due to EU restrictions) with the exception of our Cast Iron radiators, Nordic radiators/valves, Supplies4Heat radiators and West valves/accessories only. Delivery to an address outwith UK mainland will incur a shipping charge which will be advised to you by email shortly after placing your online order, this applies to the above shippable products only (Cast Iron, Nordic, Supplies4Heat, West). If you wish to order products that we are unable to ship to you outwith the UK (Trade Direct, Apollo, Reina, DQ, Towelrads, Delonghi, Stelrad, K-Rad, Ultraheat, Lazzarini) then one option would be for you to (prior to ordering) arrange your own shipping company/courier and have us deliver to their UK mainland address (they then ship on to you), to do this simply fill in the 'shipping address' at checkout with their details, we then deliver to their UK maninland address for you free of charge.
'FREE Delivery' applies to UK mainland only.
