No.

There are two things to distinguish:

PA ("provider aggregateable") address space - this can NOT be used with
a different ISP.  The customer can use it for a transition period, and
then it has to be returned to the old ISP.  You can see this if you do 
a 
   whois -h whois.ripe.net <address>

and it returns "status: ASSIGNED PA".


PI ("provider independent") address space - this could theoretically
be used.  You do not have to ask the old ISP or RIPE for permission. You 
just register the routes in the RIPE database, ask the old ISP to
stop announcing them, and start announcing them via BGP.  PI space has
other disadvantages, though, like "much harder to debug if some goal
in the Internet cannot be reached", so we usually recommend to the 
customer to return his PI space to RIPE and accept PI space from us
(unless the PI block is very large and the customer network so complex
that it would make renumbering too hard).

PI space appears as "status: ASSIGNED PI".

It might be a good idea to send one of your hostmasters to a RIPE training
- all those questions are covered in deep detail there (and it's free!),
so you don't have to ask your *sales* people about technical procedures.
