William Apologies I was not trying to ruffle your feathers, I simply mean that the scheme is not available yet, I think they were perhaps silly in giving you costings yet particularly as they don't know what the exact costings will be yet.
Its likely that the scheme costings are correct but as it says in your email in relation to the certificates is "the cost to you, we believe, will be set around £10 per certifcate."
"We believe" is not a quotation. I think its just a likely costs, a quotation you can sign and book, the scheme is not available yet, they haven't even sorted out their pilot companies.
So once they have started their beta company trials they will get a better understanding of what it will take, time allowed and therefore attribute costs.
This won't be for at least a couple of months.
I can state that the costs of certificates is not £10 NSI told me this morning "It is likely there will be no cost whatsoever for the certificate"
I think you're probably right about the costs its just the cost of the certificate I was questioning so I rang them to confirm it.
