Delivery - What to Expect
Our standard deliveries arrive via a 10-tonne lorry (similar in size to a bin wagon or fire engine), equipped with a tail lift and pallet truck.
Access must be suitable: solid, level surfaces (no gravel, steps, steep slopes, or grass).
For palletised deliveries the driver will move the pallet to the nearest accessible point, but cannot go over unsuitable terrain or carry goods indoors, though may place them inside a garage if accessible.
If you have narrow gates, restricted access, or other challenges, please let us know in advance so we can make suitable arrangements.
Our free service is a one-man delivery. We recommend having someone available to assist, especially for larger items.
The delivery driver is not able to unpack or install your goods unless this is a service you have selected.
Checking Your Delivery
On delivery of your palletised goods, the driver will wait up to 10 minutes while you inspect the item(s).
Please check your goods before the driver leaves. If there is any damage or the driver refuses to wait, note this on the delivery slip (e.g., “Driver did not wait – damage unchecked”).
For any damage found, mark the delivery note clearly and contact us immediately.
Missed Deliveries
If you miss your pre-booked delivery, a re-delivery charge may apply.
For smaller items sent via courier (e.g., stove glass), the courier will leave a note with redelivery instructions if you’re not home.
Additional Delivery Notes
Accessory items like fitting kits and liner packs may be sent separately via courier on the same day. You’ll receive email confirmation if this is the case.
Delivery times are generally between 9am–6pm, Monday to Friday.
