Nidge that is good news.
I have just started on the house move quest, the letter I had from my solicitor had pages of questions about work undertaken, drainange, sewerage, boundaries etc. I thought that is what we paid them vast sums of money to establish?! I had to give certificates of compliance for the new kitchen and bathrooms I had fitted, for gas and electrical changes that were involved. I believe any change after 2005 has to be certified. It is very frustrating. I hope you get completion OK.
best wishes
