Picking up an old thread I know, but, the thing with cutting seals, as I was once informed by someone from the DNO is this, quote, "we don't mind you cutting the fuse seal but cutting the meter seal leaves you open to accusations of fiddling the meter". Honestly, I kid you not.
The best one regarding fiddling meters came about 2 years ago from this Indian bloke who owned a curry house, when I went round to the restaurant, the 'job' was to deal with a metering issue. Being tightfisted this 'electrician' had assured him that he could reduce his bill massively by altering his wiring, he'd come back in 12 months time and put it back to how it should be, ready for the meter readers. All the guy had to do was not allow them access for the next 11 months, which tbh isn't usually a problem, so the guy does his magic, relieves the indian of £250 and the Indian guy then goes all electric, why not, it's cheaper!
However 14 months later he's not seen the original spark and to cap it all the supplier is coming on Monday armed with a warrant to enter, just when it couldn't get any worse he reads the meter and realises he's used £5K worth of electricity MORE than usual, so much for reducing his bill!
He rings a mate of his who knows me and I go round, it was a classic, the previous 'electrician' has removed the outgoing neutral from the meter and taken it straight to the cutout, so the meter is still registering the amount used! Obviously he knew sod all about metering, lol. Anyway, I very kindly put it back into the meter, re-sealed everything and liberally sprinkled everything with dust, so it looked like it had never been touched in years, then billed him £150!
Obviously not deterred by the previous experience he asked me what he should do now, so I told him, "pay the bill and don't try fiddling the meter in future, but if you do, make sure the guy doing it knows how to do it properly". I don't think he found my advice helpful, lol
