This applies to deliveries to UK mainland areas. Where your postcode is deemed to be in a non-mainland UK area then a delivery surcharge will apply. You will be notified of the price of this surcharge at checkout and full details on relevant postcodes can be obtained by calling our sales team on 01724 281044.

In addition, there will be some areas where it is not possible to calculate the surcharge through the website, an example is Northern Ireland. In these cases, you will be notified of this at checkout and you should call our sales team on 01724 281044 for a bespoke shipping quote.

EU and international deliveries are possible but will be assessed on a case-by-case basis and orders cannot be placed through the website. Please contact our sales team on the number above in order to discuss your specific requirements.

Delivery will normally be made at any time between 08:00am and 06:00pm, Monday to Friday. It is important to ensure that an authorised person is available to receive the goods. If we are unable to deliver as arranged, then we reserve the right to levy an additional charge for the re-delivery of the items. Special delivery instructions can be provided to us at checkout in order to minimise the possibility of this happening.

Some of the items that we deliver are large and bulky. Unless otherwise stated, the item will only be delivered ‘door-to-door’ rather than being taken inside your premises. Therefore, it is your responsibility to ensure that you have suitable apparatus to handle and move any item that is ordered and delivered to you. If you have concerns about this, please call our sales team as upgraded delivery solutions for larger items can be made available at additional cost.
