Greenbrook 24hr 96 Electro Mechanical Immersion Heater Timer   £17.74

Great Mechanical time clock - no nonsense design and much easier for customers to set than equivalent digital types. Wiring is straight forward - the supply & load terminals are easily accessible at the bottom - much easier than older styles I've used in the past. Also seem very reliable. ONly replaced this on like-for-like owing to a DIY'er replacing immersion fuse with 30A fuse wire on a blown element - hence goodbye time clock!I received the updated "curved" version - identical in every way apart from the front profile is now curved rather than square.Great product - Great Price & Great Service! 5/5.
