I wonder whether anyone can help.. my neighbours are being so difficult with the process- I am having my loft renovated and in order for the builders to tile the side which falls next to there roof- they have requested I give 14 days notice, I have done this which will be Monday the 14th of July- however they are now asking for a risk assessment to be carried out otherwise they will not grant access- which I understand to be deliberate and an offence under the party act. what should i do?? help please?
