Another excellent one is the Fluke T5-600 - about £80

Martindale is good. One of the best. As for proving unit, you don't have to use one. Especially if you have to pay 3 times the price of the Voltage Indicator for one of them. But you must test it on a known live source to make sure it is working.
Just a quick question, how can you prove your tester on the incoming side of the consumer unit when the Electricity at Work Regs state that the front cover must never be removed unit power is isolated, ie, main fuse below pulled out? Therefore a proving unit must be used to complete safe isolation procedure on the consumer unit.
When measuring Ze, R1+R2, polarity, etc, this is classed as testing procedures where the main fuse is allowed to be re-instated to power the consumer unit for testing purposes only. When removing the consumer unit front cover for the first time, the main fuse below must be taken out and isolated.
I had this same discussion at night college last week with my tutor regarding using the incoming supply to test voltage indicators and he said you can not remove the CU front cover until it has been totally isolated, as per EaWR regs. He also said that it is not advisable to use another source to test meters therefore a proving unit should be used. I also have an e-mail from the NIC saying the exact same thing.
