Items are arranged by similarity of application, or for other reasons, and not by stock number sequence. Often the item number serves only for stock identification by us in making up orders. Newer stock items are marked in red, so as to be more easily seen.

VAT : The prices quoted do not include VAT. However it is added to every customer's order. Local authority establishments will be able to reclaim this input VAT.

Postage : Postage and, where necessary, packing, will be charged for. It is therefore best not to send cash with an order, but wait for us to bill you. Official orders may be used.

Please try and ask for at least £10 worth of goods because the administrative costs of handling orders are significant.

Don't send cash with orders We repeat, please do not send payment with your order. Wait until you receive our advice note upon which payment may be made. This saves unnecessary complications, e.g. when items are out of stock, failure to make provision for VAT, or if a delivery charge needs to be made. Items of equivalent value may be deducted from your order to balance any shortfall.

This service supplies equipment, components and materials useful for small scale projects and other practical activities. It is not intended to compete with the mainstream educational suppliers. Rather it aims to support schools by finding a range of unusual or hard-to-find items and pass on any bulk purchase benefits.

Where we know of several better and convenient sources of commonly used components we may have deliberately decided not to stock such items ourselves. We can however refer readers to the relevant preferred suppliers.
