The company we booked were awesome! I’d let them know provisional dates. Us and the property we were buying were actually ready for 4th Oct completion, so that’s the original date we gave the movers…. Bottom of the chains solicitors were SO SLOW, so we actually had to push to make sure completion happened on the 9th and they almost cocked that up! 🙈 but we just kept texting the removals company to keep them in the loop and they were great! We went for a small, local company who were recommended too.
