thanks everyone so much for their replies, and especially to mattmoss.
here is an email i recieved from gity and guilds (the nptc people) which i have forwarded on to the guy at the council:
Good morning Daniel,
Thank you for your email enquiry. I can confirm that NPTC Certificates of Competence in Chainsaw have no expiry date and are valid for life, though we do recommend refresher training. If our qualifications expired they could clearly show an expiry date on them.
Unit CS10 is the maintenance of the chainsaw and CS16 is crosscutting. If I were to equate the units you hold to ‘current’ units it would equate to CS30.1 and CS30.2, please note that scheme criteria changes over the years and will not be exactly the same.
The chainsaw units are to be updated shortly and we will be doing away with the prefix ‘CS’ codes. I would recommend to your local council to concentrate on the unit description rather than worry about the unit number. Particularly as the units have changed over the years; for example CS32 medium tree fell, used to have an upper limit of 760mm. CS32 now has no upper limit and CS33 (large tree fell over 760mm) is no longer offered. I mention this only to highlight that to keep up to date with current industry standards and best practice our qualifications are updated every couple of years which may result in changes to qualification unit numbers. I fear that if older (and still valid) units are not being recognised many experience chainsaw users are being refused work.
I hope my response is of help to you but if I can be of any further assistance please do not hesitate to contact me.
The annoying thing about all this is, about a year ago i rang the guy at the council to report some rogue tree cutters, cutting a tree in council woodland for a householder, who dumped all the logs in a heap. He never came out to look, and later said i could take the logs. no questions were asked.
Now i want to do the same, remove some ash ( a sizeable bit for firewood), free of charge to the council, and he wants all this info.
He has even said my insurance is not enough, as i need £5 million. So i upped it today (for £19) and emailed him a new cert.
If he still drags his feet, i'm not sure what to do next, but i think i can lift the log out in one with my avant.
on another note, how do you report someone for not having a chanisaw licence? the hse website is useless!
