Hi, thank you for your product enquiry.
This British General 13A 2G SP Switched Socket + 3.1A 2G USB Brushed Iridium is 30mm deep from the farthest point at the back of the workings to the peak of the rocker switches.
The plate stands out 5mm from the wall at the centre, with the rockers standing a further 4-5mm beyond that, so a 25mm box will be sufficient for most installations (assuming there is not an excess of cable sharing it with the socket).
