Cleaning before moving house?

[Flissty]

Hello,
We are in the process of buying and selling house (oh the hellish process). I quite like the young couple we are selling to.
My question is - how much cleaning do people normally do once they have moved their furniture out? My understanding (never done this before) is that on completion day there’s very little time, just get the furniture loaded into the lorry and go. But there is always dust and dirt behind furniture - even though I promise I do have a clean house! What is normal, do people move in and expect to clean clean clean or should I be running around vacuuming as the movers shift my stuff? What is the normal expectation when buying a house?
Thanks!

Clean oven, fridge and run down food in integrated freezer in advance. Clean skirtings a few days before you move. After rooms are empty run vacuum over and steam mop kitchen and bathroom floors. Whatever you do leave toilets clean. Throw toilet fizzers down toilet bowls. Wipe over surfaces.

I always do a final vacuum and wipe down after everything's out. Leaving it clean makes such a difference for the new owners.

Also, for moving out, I always do a thorough clean including behind furniture and taking the hoover for a final pass, then leave a small gift. If you are short on time or energy, I have used Help Mate Services for a deep clean before and they handled it perfectly, saving a lot of stress.
