Good question Wigwam. I think my area is pretty well served by registered TrustMark companies. There are 3 local companies within Doncaster boundaries, All of them are dedicated External wall insulating companies. That is to say, They are well known contractors, specialising in EWI External wall insulation.
So far 2 out of the 3 have contacted me already. Just waiting for the 3rd to get in touch.
From my understanding, If you can not manage to get 3 quotes then 2 will suffice.
Your best bet is to contact https://www.simpleenergyadvice.org.uk/ and tell them you are having problems get the three quotes required. You might want to visit https://www.gov.uk/guidance/apply-for-the-green-homes-grant-scheme
Just out of interest Wigwam, is it external wall insulation that you are after?
