Hi all, I'm looking for some advice on how to deal with a dodgy contractor. We have started a small scale renovation about 4 months ago, moving to temporary accommodation to avoid the dust as I'm pregnant. We agreed on a price (and had 30% of the budget as contingency). The project is now delayed by a month and almost 50% over the budget. We already paid him all our dues but told him to not to exceed the budget any further or provide us with evidence of extra costs. Now, the builder is threatening us to stop the work if we don't keep paying him going forward. TBH I think he's trying to take advantage of our situation now that I'm 8 months pregnant and stuck in a small flat with 2 cats. He knows that we are desperate to move back to our home. Is there a good way to deal with this situation? Arbitration perhaps or maybe starting the legal process to claim damages? Grateful for your advice. We are based in West London if that's relevant. TIA!
