Sandilands Electric Ltd, trading as S.E.L Networks, is a London-based data networking specialist serving domestic and commercial clients across the south-east of England. The company designs, installs and maintains comprehensive structured cabling systems, from Cat5e through to cutting-edge fibre optic infrastructure.

They work extensively throughout London, Greater London, Essex, Kent, Surrey, Hertfordshire, Buckinghamshire and Berkshire, handling everything from initial network design to ongoing maintenance and troubleshooting.

What distinguishes S.E.L Networks is their dual expertise in both passive cabling infrastructure and active network equipment.
