About garden lighting installation in Kingston upon Thames
Garden lighting transforms your outdoor space into something you can enjoy year-round, from subtle path lighting to dramatic tree uplighting. A professional installation covers the full design — choosing between low-voltage 12V systems and mains-voltage fittings, selecting the right IP-rated fixtures, positioning transformers, and running cables safely underground. Most garden lighting projects are completed in one to two days depending on the number of fittings and complexity of the cable runs.
Any new outdoor electrical circuit is notifiable work under Part P of the Building Regulations. Mains-voltage garden lighting must be installed by a qualified electrician registered with a competent person scheme (NICEIC, NAPIT, or ELECSA). Even 12V systems fed from an indoor transformer benefit from professional installation to ensure waterproof connections, correct cable burial depth, and compliance with BS 7671 Section 714 for outdoor installations. Poorly installed garden lighting creates shock and fire hazards, particularly in wet ground conditions.

Garden Lighting Installation FAQs
Should I choose 12V or mains-voltage garden lighting?
12V systems are safer, cheaper to install, and easier to extend — ideal for most domestic gardens. Mains-voltage (240V) fittings are brighter and better suited to large gardens, long cable runs, or situations where you need high-output floodlighting. Your electrician can advise based on your garden layout and the effect you want.
What IP rating do garden lights need?
As a minimum, garden lights should be IP44 (protected against splashing water). For ground-recessed fittings, path lights, or anything at ground level, IP65 or IP67 is recommended — these are protected against jets of water and temporary submersion. Pond lights need IP68.
Can I add more lights to an existing garden lighting system later?
Yes, both 12V and mains-voltage systems can be extended. 12V systems are particularly easy to add to — most transformers have spare capacity. For mains systems, additional spurs can be added from existing junction boxes, provided the circuit can handle the extra load.
Do garden lights need to be on a separate circuit?
For mains-voltage garden lighting, a dedicated circuit from the consumer unit with its own RCD protection is strongly recommended and often required. 12V systems are typically powered from a transformer connected to an existing indoor socket or lighting circuit.
How deep do cables need to be buried in the garden?
Mains-voltage SWA (Steel Wire Armoured) cable must be buried at a minimum of 500mm with warning tape laid above. Low-voltage 12V cable should be buried at 150-300mm. All buried cables should be routed away from areas likely to be dug over.
