In theory, all leased services are available anywhere...it just depends how much you want to spend on ECCs...the most I have spent is just over £500k for one site - but that's an exception!
The fact that you have a fibre presentation already means you should be able to order 10Gbps and provided that it's not damaged or destroyed like the copper I'll stand by my no ECCs...that won't get confirmed until it's surveyed though.
Good luck and keep us informed on progress.
