PowerPerfector and their "voltage optimisation" wank. They've only gone and installed one where I work, despite me trying to discourage them. Retarded...
http://www.powerperfector.comThey come and install a hideous, useless, bright green box:

They come to your place, take a few "measurements" and produce a report showing the "amount it will save" with a sufficient amount of zeros on the end. The savings they claim are in the order of 9 to 13% - I reckon this would be around the expected level of fluctuation between any two years of usage on a normal mains supply anyway.
The counter on their website (here, top right:
http://www.powerperfector.com/Media.html) just increments once a second at a predetermined rate. The top one (kWh) increments 17 per second. The bottom one (£) increments at £1 per second. That’s about on par with the price of gas per kWh, not electricity. It even resets back to £303,254,134 or if you refresh the page!
This doesn't even tally up with the cost of electricity - 17 kWh would cost more like £2.36 at the average rate of 13.86p per kWh (it's what Google said).
PowerPerfector are currently dissolved with a net worth of £100 on last published accounts, with £0 in the bank.
It appears that “Intelligent Energy Saving Company” now own them. Their registered London office houses 30 companies – of which, five have £0 in their bank account, one has £1 and seven have a net worth of less than £2. Around half of them have no accounts info, including the company in question. So, it's a PO box, which is sufficient for them to say that they have a London office or head office.
PowerPerfector and EEVS (The Energy Efficiency Verification Specialists, who seem to verify the energy efficiency/savings claims made by PowerPerfector) have been colluding together in a sort of back-hand deal:
