You can test your delivery postcode at the first step of the checkout.
A surcharge applies for orders that include a 'bulky item' or where the total weight is over 30kg. A 'bulky item' will highlight itself on the product description page. A surcharge also applies for orders that are being delivered to a UK offshore postcode. This surcharge is discounted when you spend over £99.
Our working days are Monday - Friday.
Only for in-stock items (on the product description page it will display either 'next day' or '3-4 days dispatch'). Order by 2pm for items that trigger a 'freight rate' surcharge at the checkout (e.g. heavy generators and table saws) as well as anything that includes gas canisters (e.g. Paslode nails). Please allow an extra day for Scottish Highlands postcodes. Freight items can not be delivered offshore.
Untracked 4-7 working day delivery (small parcels).
We can now provide low-cost delivery for certain small parcels of up to 2kg for orders under £99. This service is provided by Royal Mail (currently on a 4-7 working day service if in stock).

This service won't accept any combustible items such as canisters, cartridges or lithium batteries.
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.
