Yea Phil
a couple of firms tried to take the levy from me in the 80s,90s
The CITB levied the big contractors with a turnover of over a £100,000 or so
some tried to pass this on to thier "labour only"employees in a form of a deduction.My labour only earnings were well under the £100,000 limit and I was not connected in any way and recieved no benefit from the citb
It was just another accountants scam to take money from the lads on the tools when I accused them of making illegal deductions from my earnings they soon backed off and repaid monies already deducted
