In a previous thread I mentioned the regions in England that clubs fall into, I happily admit that I was off with a few of them so I will refer to the 9 regions as set out by government and the counties withing those regions.
North West is, Cumbria, Lancashire, Greater Manchester, Mersey and Cheshire
North East is, Northumberland, Tyne and Wear, Durham and Cleveland
Yorkshire and The Humber is, North Yorkshire, West Yorkshire, South Yorkshire and Humber
East Midlands is, Derbyshire, Notts, Lincolnshire, Rutland, Leicestershire and Northants
West Midlands is, Shropshire, Staffordshire, West Midlands, Herefordshire, Worcestershire and Warrwickshire
Anglia is, Norfolk, Suffolk, Cambridgeshire, Bedfordshire, Hertfordshire and Essex
Greater London
South East is, Buckinghamshire, Oxfordshire, Berkshire, Hampshire, Surrey, Kent, East Sussex, West Sussex and Isle of Wight
South West is, Gloucestershire, Wiltshire, Somerset, Dorset, Devon and Cornwall
I propose that your clubs region is determined by which county you are in. Of course this is not for me to decide, just my opinion.
