As soon as you have an estimated moving time let your preferred removal company know so they can pencil you in. As you get through the legalities and paperwork you should ask your solicitor regularly for an estimated exchange and completion date. Don't expect them to advise you of this and you should ask them for a completion date and any changes of date weekly or daily as the time gets nearer. It is surprising how much you have to chase and communicate with your solicitor during the moving process and you will find the sellers and buyers that chase and follow up will move a lot quicker than the ones that just leave it to their solicitor. When they give you a completion date this is when you can contact your removal company to book them. Larger and more established removal companies will have more flexibility of moving you as they will have lots of removal vehicles and removal crews compared to one person setups with a van.
