I had this post in the news section because somehow i hadn't seen this one so here's a repeat :
Thought i'd start off a list of good places for UK supply, including net sources and local sources by city.
Here are the net ones i have used with my comments on them :
SOURCE :http://www.mutr.co.uk
COMMENT : These people are amazing ! They have everything from gears and cogs, through electronic components, to smart materials.
Their minimum order is £10.00. They are VERY cheap but unfortunately their delivery time is ten days

They are a university resource here in London. Unfortunately you can't go and pick up your stuff

SOURCE :
http://www.maplin.co.ukCOMMENT : Good pricing, fast delivery and local shops over the UK. Smaller outlets seem to have lower stock supplies.
SOURCE :
http://www.wires.co.ukCOMMENT : Every sort of wire you can imagine. Good prices. Really helpful and fast delivery times. They even sold me 100 empty plastic coil formers for 8p each

They don't normally do this but i told them i was part of an electronic hobbyist group and would get them more orders.
SOURCE :
http://e-magnetsuk.com/COMMENT : Cheap, fast, good customer service. Slightly limited in magnet variety, be it ferrite or neo. Do custom magnets but not large sizes.

http://first4magnets.co.uk/COMMENT : Cheap, fast, good customer service. Good variety. Do custom magnets but not large sizes.
SOURCE :
http://www.supermagnete.de/eng/COMMENT : Neo magnets only. Good pricing and variety. Friendly customer service but P&P higher because they are in Germany.
SOURCE :
http://www.magnetec.de/magnetec.htmCOMMENT : Yum-yum, they do nanoperm

Good pricing and delivery, helpful CS but again P&P higher because they are in Germany.
SOURCE :
http://www.t2retail.co.uk/COMMENT : Good prices, good delivery.
SOURCE :
https://www.circuitspecialists.eu/COMMENT : Good prices, fast delivery. This is where i got my 18V, 2A DC PSU for £40.00.
As for local offline sources (LOL i suppose i mean shops !), I live in London and the only dependable source i have found is Maplin, though my local branch don't do Hall Effect sensors !
Hope, this helps, please add to it
