Quick update. We had lots of quotes and in the end did go for Jamescape. Although not the cheapest (they were about in the middle costwise) it was the two meetings we had with them that sealed it as my partner and I felt we could work well with them and any problems could easily be sorted. And we felt it was value for money.
Hoping to start the work in April so lets see what happens and I hope it all goes well.
As an aside, one person who came out to quote (not recommended on this forum), perfectly nice man but he used the f word constantly

. My teenage boys were in the house and I thought it highly inappropriate to swear in a family home on a Sunday afternoon when quoting for some work to be done. I know the boys have heard it all before but I still thought it was a very wrong sales pitch.
He was the cheapest and might have got the business if he hadnt been so careless with his language.
What a silly f-f-f-fool he was then
