don't clean anything until the work has been finished.
Dust will get into drawers, cupboards, carpets, bedding and lampshades, and through closed doors. After taking the bedding off, put a dustsheet over the mattress. Disposable plastic decorators roll will do, but dust will fall off it when you take them off.
But a generous quantity of those plastic storage crates with a tight-fitting lid. Buy a roll of recycling bags (they are like large bin-bags, but clear. If you put your possessions in rubbish bags, they will get thrown away, or, at the least, dirt and teabags will be thrown in them.
Electronic items such as PCs, tablets, hifi and TV will be ruined by dust getting in them. Put them in bags, then into a crate.
Dismantle your domestic vacuum cleaner and take it out of the house. Ask someone else to look after it until the builders have left.
Buy a builders canister wet-and-dry vac. It has a cartridge filter that can be brushed clean (outdoores) but but fleece bags to fit, or the dust will clog the cartridge too soon. As well as the bags, buy one spare cartridge. If you can't get replacement bags and cartridges to fit, don't buy the cleaner. 30litre is common. This one will be handy for DIY in future years They are quite cheap but have a good guarantee that lasts longer than your building work will.
"Wet" and dry means you can suck up water and wet material from overflowing baths, burst pipes and blocked drains. They are quite noisy.
If anyone in the house has athsma or other breathing problems, buy a box of dust masks with the plastic valve on the snout.
Have you drawn up your plan of sockets, in every place where you might ever want one? Including more than you consider necessary in the kitche, utility and garage?
RCBOs are worth the extra on your socket circuits (upstairs, downstairs, kitchen and utility room)
