Worth getting quotes from destination movers and home town movers. I moved 180 miles, 4 hour drive.
We agreed it as a 3 day move, with 2 vans, (contents of a decluttered 3 bed house) and had asked the chain for at least a week and a half between exchange and completion, to make things easier.
Pack and load a lorry-full, all but the beds, the day before completion (which also gave time to clean the bits behind fridge etc the night before). (This bit only took half a day). Obviously a risk assuming everything will go ahead with completion, but thought it was worth it.
Day of completion, pack and load last bits up (only took an hour). Pick up load from Big Yellow which had been there to declutter. Final touch of cleaning (hour). Left in advance of completion. (Completion in our small chain with only one purchase below mine, wasn't till 4pm). Drive 4 hours. Completion en route. Pick up keys.
Removal company had got airbnb to stay overnight, but were keen to get on. So we moved in then 430pm - 730pm, including reassembling furniture. However I think it probably depends on their assessment of how well organised things are (eg had all the boxes from Big Yellow marked with which rooms), and how much stuff you have. They left me the choice and we could have done it in the following morning.
They then stayed overnight, drove back in morning. This cost £2850, with 2 to pack on day 1, and 4 to load and unpack on day 2. I got 4 quotes and this wasn't quite the cheapest, and there was a variation of £1000, with the ones from destination, who were relying on whatsapp video calls to assess load the more expensive.
Different companies suggested different ways of doing this move, with 2 day ones also suggested. Talk it though with the people doing the quotes, and I'd suggest go for the ones who seem most competent. It is really stressful.
My tips: mark all the boxes you pack with the room they are going into/contents. Put marked tape over the doorways so they are clear which room is which. Put asterisk on key boxes so you know to unpack them first.
Join facebook groups for new area in advance. Found this invaluable to get up to speed on live issues and as did searches on them for reliable tradespeople, and we needed several of them to sort out issues immediately after moving in (burglar alarm, etc).
Good luck.
