I am trying to sell my house and have been asked for consent from my local Council for my renewed double glazed windows and doors and for a garage door that was put on the front of an old outhouse. I don't have these. The window company has gone bust and my husband put the garage door on. What do I do? They have also requested a building regulations certificate for the cavity wall installation. I have e-mailed the company that did it and hopefully they can supply this for me.
