Do not leave planning to the last minute as this will only lead to increases in stress.
Plan everything properly and make a list for moving, and contacts for helpers, and van hire details.
Rent a vehicle that is the best size for the job.
Use only best quality packing boxes. Resist the temptation to pack everything into binbags as you’ll only damage or misplace items. Good Cardboard boxes are durable and can be labelled properly.
Get rid of unwanted items beforehand as there is no point in taking that stuff with you. You may as well dump or car boot sale.
Get loads of friends and family to help you at both ends of the move.
Place your dogs and cats or other animals with a kennel or minder for the day. They will be unfamiliar with the new surroundings and can easily wander off with so many doors being opened to walk furniture through and they could become lost.
Tell the Gas, Water, Electricity and Phone companies you will be moving a month in advance as some need notice.
