-Tent - Double layer in case it pisses down, for comfort I would go for at least a 2 man but probably a 3 man so you can get all your stuff in it as well.
-Camping fold up chair
-Blow up bed
-pillow
-duvet - it gets VERY cold on nights, even in the middle of summer
-Torch
-mallet
-BBQ, a cheap £10 one from Asda/Tescos - will last you all year or buy disposable ones but a proper one will cook better and you will get use out of it. If you get a proper little one then you can buy the instant lite bags, very quick and handy and no messing around.

-cooking utensils
-Plates, cutlery, glass,mug (plastic)
