We have engaged Xchange Master Ltd to handle the stamps.

Xchange Master Ltd will send pre-paid C4 size gusset envelopes free of charge.  The stamps are put in them and sent to Xchange Master Ltd again free of charge.

Or for bulk pickups (i.e. more than 3kg) Xchange Master Ltd can arrange for a courier to pick up from any premises in the UK (excluding the Channel Islands) on a day that suits or alternatively or send a label for the client to drop off at a local Hermes/ UPS/ DPD drop off point, again free of charge. There is usually a drop off point within one mile for most postcodes in the UK.

Stamps should be on single thickness backing paper (i.e. not front and back of the envelope) and the backing paper should be trimmed to about 4mm to 8mm.  Nothing else should be mixed with the stamps (e.g. coins, postcards).  A variety of stamps may be submitted together. Please remember to send your supporters slip (found inside the envelope) when you send your stamps off to Xchange Master.

To receive either the envelopes or the courier service, please email  Please ensure they are aware that it is for USPG.
