Rucksacks./Bumbags. for day walks, with comfortable straps ,as long as its big enought to hold all day walking kit.
Gaitors.. These are waterproof covers for your boots, they are not essential but a good idea to keep your feet dry, and can reduce mud getting on your trouser bottoms.
Walking Poles. A personel choice, good in muddy conditions, and are said to reduce stress on knee joints and good for testing puddle depth/hacking down nettles
First aid kit. A small basic first aid kit. You can but these ready made in Tesco, Boots or just make your own up.
Whistle. Any type of whistle,(as long as its loud) ensure it is on a length of string.
