The push down mechanical ones or digital timers just don't last in my experience.

Clas Ohlson used to do a wonderful electronic timer called the esic ax300. None have failed and some are over 5 years old now. Unfortunately, Clas Ohlson moved to the Amazon so I won't be visiting again. The other one I still have after years is an unbranded square one. I have no idea where I got it but it is simple and intuitive to programme and totally reliable.

If you have a reliable internet connection , you could consider smart plugs as a timer . Lots are surprisingly rated for 1.8 Kw and it gives you the added bonus of being able to control them remotely.

To clarify, they don't need internet connection to operate, just for the initial setup and potential manual control.

I just got some Masterplug digital timers from Argos. I have always loved Argos as the name comes from the Ancient Greek for idle or lazy. I can't tell you how reliable they are yet, I just have them charging. I can tell you they are narrow enough to sit comfortably side-by-side on a fourboard (4 socket extension lead or whatever you call it). They only overhang at the top by under 5cm.

Having searched again I found the square ones I mentioned are probably from Wilkos. They won't sit next to each other.
