NEW & Improved Secure Deliveries

PIN code verification at your doorstep

We've improved the security of our deliveries to you with DPD's PIN code verification system. We will be using this service on most orders to ensure your parcel gets to you securely.

You will receive a PIN code via text and/or email which you must recite to the delivery driver on arrival. If someone is receiving the parcel on your behalf, remember to pass on the code to them. The driver can also resend the PIN code to the original contact on arrival if required. This service requires a mobile phone number with your order so please ensure you provide one to take advantage.


- Our deliveries are very easy to track, plus you'll get a handy 1 hour delivery window so you know when to expect your items. You'll receive a tracking number with your 'order dispatched' email.

- Your VAT invoice is always in the box with your goods.

- Your goods are always securely packaged when leaving our warehouse. We strive to ensure your goods reach you in prime condition.

Our main courier is DPD. We use DPD for the vast majority of our deliveries. APC and TNT handle other specific types of deliveries for us. In poor weather conditions our couriers may experience delays that are out of our control, however we will help you in every way possible to track delivery progress.

- Delivery to construction/job sites is possible, but done so at your own risk. Our service can deliver to an address, but we can't guarantee delivery to a specific person or location at the address. For the best outcome, please provide detailed courier instructions and a contact number that we can pass on to the courier.

- Delivery to 'safe place' is not available for most orders, someone must be present to receive your delivery. We do this to ensure our couriers deliver to the right person at the right address, to ensure your goods are not lost or stolen. Particularly as most orders are of high value.
