Keep a close eye on everything the RPS does. They will do their own calculations, only loosely based on information you, the insolvency practitioner or any tribunal judgment provide. They are very reluctant to be transparent about how they arrive at final figures. In my case they made a number of significant mistakes and used methods of calculation that can only be intended to whittle down the amount owed. No explanation provided for the discrepancies. It took quite a while to get through the half answers to find out the truth and get it rectified.
For a number of reasons beyond my control I’m coming up on 4 years now and still waiting on a final payment for holiday entitlement from the insolvency practitioner. The RPS were reasonably quick when it was their turn but overall it has been a long process that probably would not have been worth the bother if I wasn’t determined to see it through, initially just to give my old company a kicking (let me assure you they deserved it), later just to finish what I’d started. Out of several hundred employees less than a handful got this far. Much of the lost time has been a novice insolvency practitioner that didn’t realise the clusterf*ck they were getting into. Good Luck!
