URGH, I feel your pain. We had the house next door to us being refurbished for new tenants (it's private let,) and the landlord's brother did it. He did it over Easter 2.5 years ago, and was in over Good Friday, the Saturday, Easter Sunday, and Bank Holiday Monday (as he was doing it in his own time!)
He was refitting the kitchen and bathroom, and putting new doors in. He was in at 7am over the 4 days of the Easter break, banging and knocking and drilling and sawing, til 10pm. I could have fucking murdered him.
Me and DH had the 4 days off together, and were looking forward to a few lie-ins, a few chilled mornings of watching films and supping lattes and eating muffins, and generally relaxing.
Not a chance. We were beyond fuming. It ruined our time off completely, and we were shattered for the entire 4 days, and then knackered at work all week. (We went back on the Tuesday after Easter.)
Even for 2 weeks after, he banged and drilled and sawed and knocked and played the radio loud from 5pm to 10pm every night! 
On the plus side, the new tenants/neighbours are really lovely, and very quiet, and we get on really well. 
But yeah, if I was you OP, I would contact the council about this pub work.
