well, I would have to say I love my SeeSnake Micro inspection camera - I bought it for a one-off cabling job after trying for 3 hours to fish a cable with a coat hanger from behind some plasterboard and I've since found 100 other uses for it.... Not to mention the kids love it for looking around corners!
In no particular order, Fluke continuity tester (too many belts off leccy showers/badly fitted boxes in kitchens) Bosch GBH sds drill/gun, pays for itself every time I get it out of the box. Telegan Sprint V2 FGA with printer/thermometer clamps open ended spanners 6-20mm inclusive, plus 22, 24, 30/32 BAHCO pump pliers Bosch Multitool 24" stillsons Monument 'wriggley' tap spanner Basically I have a waaaaay too big/heavy FACOM carry bag that has mebbe 50 crucial tools that you just know you 'might' need to complete a task, but of course, we need more various tools than any other trade on an hourly/daily basis don't we? DH
24mm open-ended spanner cut 1/4 short, and grind off some of the cheek. Ace on 15mm compression fittings. The Monument one is a load of tihS even though it's less than £3. I dunno what Monument used to get that size spanner, but it fits nothing in my well stocked van!
I brought a telescopic magnet and its a gem for getting screws that you have droped where you cant get your fingers, if its a realy tight space like down the plughole put a big screw on the end and the screw becomes magnetic its even strong enough to pick up my adjustables. great stuff
Of course, no self-respecting Plumber should leave home without has Bahco wide jaw adjustable spanners, 10,15,22 & 28mm pipe slice & Nightlite LED torch.

ERBAUER 10.8 volt mini drill allways in box. saved many a trip to van (must have decent masonary drill kit) same battry for multi cutter as well
The Gerber pocket sharpener gets my vote. For less than the cost of a pint, this tiny tool keeps my every day carry knife, plenty sharp enough for work. Well, that and my DW743 flip saw of course. Opposite ends of the tool spectrum for you........£3 to £600
