To find out whether you are likely to have the mobile coverage to allow a good 4G internet connection, enter your location’s postcode into this online tool from Ofcom.

Select the ‘4G’ and ‘Outdoor’ boxes and the tool will show you a list of the mobile networks in your area. Look for green ticks under the ‘Enhanced Data’ column on the right – these indicate that this network should give you a good mobile internet connection at your site(s).

For more detailed information, or to get an idea of coverage at multiple locations, click on the ‘View map of available services >’ button at the bottom right – this will show you a map of your area and whether you are likely to receive ‘Good coverage’, ‘OK coverage’, ‘Some problems’ or ‘No coverage’ for the network selected in the drop-down menu at the top left.
