Dobies - Veg and flower seeds, nice selection of fruit trees/shrubs plus herb driers, potato trays, potato scoop etc!
Sarah Raven - Handy kitchen tools, jars and bottles, beautiful ideas as well as great plants and seeds.
The Real Seed Catalogue - I have only recently found this west Wales based company, but the seeds look amazing, all sorts of rare varieties and ones which have been proven (by themselves) to work in the UK climate. I'm excited to try some out!
Heidi's Happy Hens - Just of the M6 in Leicestershire, a great place to buy hens of many different breeds. Take the kids as there are animals to pet and a climbing frame area.
Merrydale Poultry - A good seller of chicken in the Midlands area, they know their stuff.
