As others have said, pay someone. But as you have a van and it's only 10 minutes here's a few, IKEA do cardboard boxes which can hold about 30kg and are decent, or boxes from the shop will work just know their limit.

Don't pack all books in one box and all light stuff in another. Put a layer of heavy stuff at the bottom of all boxes and a full to the top with lighter stuff like bedding and clothes. Your back will reward you by not being broken!

A dolly will help moving the boxes as well as white goods. You can get one fairly cheap from Screwfix or buy second hand.

Try and fill boxes with stuff by room and by priority it will be needed after the move, label them with the room and contents, and pack in reverse order. You want all the important stuff packed into the van first, then when you unload it into a room the important stuff is easily accessible.

Don't forget the moving day box of stuff you will need. Such as charges, kettle, cutlery, cups, toilet roll etc.

It makes it so much easier to clean when it's empty so if you can clean before filling a room. So pack another box with cleaning stuff like hoover, cloths, mop, brushes, dusters, cleaning spays and liquids, or load that and the moving day box in your car/front of van.

Have an ordered check list (on paper or your phone) of stuff you need to do like checking meters, dropping keys off, cleaning, setting up broadband, registering with council tax, registering for voting, updating addresses, setting up post diversion. That way you won't wait till the day before the move to sort internet or forget to check the meters on the day, speaking from experience.

Also set up bed/bathroom once in before doing other random stuff, you will get to a point where you want a shower and a sleep, don't want to be making a bed or digging out your tooth brush at that point.

Then order yourself a big ol' dirty kebab, neck a beer and collapse, the rest of unpacking and cleaning is future yous problem!
