Plan" which is normally not definitive, but which identifies the land within the title on the Ordnance Survey map. It is important that the original title deeds are retained as they will provide a starting point if ever it is necessary to identify the precise position of the boundaries. In addition to being the government body that registers the ownership of land and property in England and Wales, HM Land Registry is also a useful tool for property investors who use the online price calculator to query the latest monthly residential property prices. The government is also using the land registry data to assess property values for tax purposes. Offices HM Land Registry has 14 offices at: Birkenhead, Coventry, Croydon, Durham, Fylde (Warton), Gloucester, Kingston upon Hull, Leicester, Nottingham, Peterborough, Plymouth, Swansea, Telford and Weymouth. HM Land Registry's Head Office is based in Croydon. The in-house IT department (Information Systems) and Land Charges Departments are based in Plymouth. In 2006, as a result of a review of office accommodation, HM Land Registry announced the closure of several offices. This involved merging offices in Birkenhead, Durham, Lytham/Warton, Nottingham and Swansea, and closing of offices in Harrow and York.

The economic recession and lower volumes of property sales and mortgages meant that HM Land Registry's basic work in connection with remortgages and house sales reduced to the point where it made a financial loss for the first time in many years. HM Land Registry announced proposals to close five offices at Portsmouth, Tunbridge Wells, Croydon, Stevenage and Peterborough. As a result of consultation, the plans to close the Croydon and Peterborough offices were not carried out, but the closure of the other three went ahead, although until 2013 a small office remained at Portsmouth as a sub-office of Croydon. The Head Office moved out of its famous Lincoln's Inn Fields building in March 2011 and is now based in Croydon. The building has been purchased by the London School of Economics for a sum of £37.5 million. During the early part of 2011, staff based in the Plymouth office were relocated to the Information Systems office in Seaton Court.
