We are moving soon, have not found a place to buy and will have to move in with my mum. We have a three bedroom place so lots of furniture and belongings, only a small part of which will come to my mum's. We don't know how long we will need storage for either. We are in Central London which probably does not help prices. What is the cheapest way for us to store things? Is it best to use the removal company to store, or not?
