There are lots of options here, but mainly they fall between the practical items and the entertainment items.

Practical items could be considered a vacuum cleaner (not a typical present - unless he really wants one of course!), alarm clock, electric shaver, etc.

Entertainment items are a lot more fun (naturally) and could include upgrading your old TV to a flashy widescreen plasma type, a portable CD player, DVD recorder, new hi-fi, etc.

Don't forget the accessories too, such as recordable DVD's, or the latest CD from his favourite artist to play on the new hi-fi.

Digital cameras are improving all the time and you can now get extremely high quality images from a camera costing little more than £100. This could be the start of a new hobby for him or perhaps it would be a good second present idea to record the experience of an activity day or holiday.

Perhaps he's already a photographic buff and has some serious kit. What about an accessory to go with that? A memory card, new lens, filter kit, photo-paper for his inkjet printer, etc.
