form SIM

Many of you will now be familiar with our free MapSearch service and are using it to find out whether a property is registered, view its location and obtain its title number and details of tenure.

More than 3 million enquiries were made in MapSearch in the last 12 months. But we realise that some of you are still lodging applications for searches of the index map (SIMs), particularly for large or complex areas.

Did you know we can speed up your index map search if you can send us compatible spatial data describing the area you wish to search?

We have been obtaining spatial data from customers for several years now and when used appropriately it can benefit both us and you by reducing the time we take to process your application.

It is a useful addition to and not a substitute for the usual SIM requirements of a form SIM and a plan as set out in Practice Guide 10 Official search of the index map.

Spatial data is created using GIS (Geographical Information System) software. Most large developers, utility companies, planning consultants, local authorities and other similar bodies are likely to have a GIS.

The file formats we can accept are ESRI shapefile (.shp), MapInfo (.MID/.MIF) and TMF.

If you have available spatial data that you believe may assist in processing your SIM application please email us.

Our requirements for spatial data

  • We can accept the following file types: ESRI .shp, .MID/.MIF and TMF.
  • Polygons must be captured against large-scale Ordnance Survey mapping.
  • Coordinate reference system OSGB 1936 British National Grid must be used in order for the polygons to be compatible with our Land Registry mapping.

Spatial data cannot currently be lodged through the portal or Business Gateway but as an attachment in an email.
