Worth trying to talk with a regional architect with the National Trust or English Heritage, they would have a list of folk who shouldn't do too much damage. We had a local company do our beams in our cottage, meant to have had lots of recommendations on their website but they damaged a ton of plaster, plus the dust was incredible, stick a mask on and carefully keep an eye on them.

I was involved with dry ice blasting in Japan when I worked out there. It's a very clean process and would do little damage I feel. It was quite expensive if I remember correctly but that was probably because it was Japan and quite new at the time.

We were going to have the beams in our last house blasted but the builders did nor recommend it. On their advice we got the conservation officer in for advice. He told us that the beams would probably take the blasting but there may have been weak areas that would be destroyed if the operator did not take extreme care.
As an alternative he suggested trying Peelaway - http://www.wood-finishes-direct.com/product/peelaway-one If worked well but is a messy and time consuming job but the end result was excellent.

The peelaway 21 paint stripper is great for stripping doors, but it can darken hardwood beams. I now use nitromoors with good results.
What ever you use you need care and patience, as just under the thin crust of the beam, may be a fragile wood worm eaten dusty sponge like wood. |

Nitromors didn't work on ours as the paint was so thick and rock hard !
I have heard that Peelaway may darken hardwood but as ours were black to start with anything was lighter !! Good result on those beams though

Thanks very much for your feedback chaps,
I will do some research in the week, and try a find out a bit more about the process. I know one thing, it's going to get messy! 
Sadly I'm not sure about the Nitromorse? There is just way too many to make it an option. And I don't think I would have the time to be honest. I will give Julian a shout Andy, I've been meaning to talk to him for a while. Cheers guys 80" 80" 86" 88" 90"

Dry ice blasting is the least messy of all the blasting processes as the blast media (frozen CO2) sublimes into the atmosphere and essentially disappears. You have to be careful using it in confined areas because it could deplete oxygen but should be ok for blasting beams as long as they are not fragile but that applies with a lot of blasting processes.
