Longer answer ...

Standard cut/paste reply to a 'missing socket' topic would be ...

Have you checked to make sure there is no other kind of connection? Sometimes there is no wall box, just a trailing cable. The cable could be hidden within, or behind, furniture. Occasionally only a very short stub of wire is left behind often hidden within a blanked-off fitting. A few examples of the kind of things to look for are in the images below from past topics.

A wall box may be branded with the logos of an old cable TV company (not VM). Past occupiers of your property may have removed the cable and sometimes they are removed by other installers, such as satellite TV techs.

If you have a cable/plug trailing from the wall, you may need a coupler adapter to join two plugs together

Also available from the likes of Screwfix, Toolstation etc.

If you have a plastic omnibox outside on the wall (where the VM cable comes in from the street) see if you can trace any wires from that into your home. The wall box will look something like these

(styles and colours may vary and branding may be non-VM (such as former cable TV companies).
