What are the names and addresses of all the CCTV Consultants in the UK?

There is no single list of security consultants for the UK market
(This will change with government regulations being introduced in the
next few years, but whether or not that will be publicly available
information is another question).

If you are looking for consultants, and those who specifically
specialise in CCTV, you may want to contact the following
organisations:

Association of Security Consultants =
http://www.securityconsultants.org.uk/
CCTV Users Group = http://www.cctvusergroup.com/
British Security Industry Association = http://www.bsia.co.uk
NACOSS (gateway to accredited installation companies) =
http://www.nsi.org.uk/nacoss1.htm

How do I put a stop to this offer?

Sorry you weren't satisfied with the answer that I provided.  I
realise after reading the comments from tar-ga that you may have been
looking for security consultants rather than CCTV consultants.  The
FAQ explains how to repost the question, or request a refund.
