The Small Print Stuff

You should never book fitters before you have received your goods, we cannot be held responsible for costs incurred by yourself as a result of delivery complications and/or delays.

Deliveries are palletised and heavy, therefore our delivery services are to kerb-side only – you will be responsible for moving the goods from the roadside to the property.

Shortly after placing your order, you will receive a delivery date confirmation email. This email will detail the day of delivery which can take place any time between 8am and 6pm. If you require a more accurate time slot, please contact us prior to ordering and we’ll do our best to assist you; this could be at an additional cost.
