Alpkit do custom frame bags for a reasonable prices.
Revelate is considered "Gold standard" but it's wicked expensive and only seldom comes up on eBay.
Decathlon do stem bags for £5 and also have a bike packing range, but it feels like their stuff is probably made in sweatshop conditions given the pricing. (I have two, and would be happy to be proven wrong)
Front bags depends a bit on whether you want a "dry bag harness" type bag or a carradice style saddle bag on the bars.
