How it works
Design consultation
Your electrician walks the garden with you to discuss the effect you want — path lighting, uplighting, feature lighting, or a combination. They assess power supply options, cable routes, and recommend 12V or mains-voltage systems based on the layout and your budget.
Cable routing and groundwork
Cables are routed from the power source to each light position. For mains-voltage systems, SWA (Steel Wire Armoured) cable is buried at a minimum depth of 500mm with warning tape above. For 12V systems, low-voltage cable is buried at 150-300mm or run through conduit.
Transformer or circuit installation
For 12V systems, a weatherproof transformer is mounted in a sheltered location and connected to an indoor circuit. For mains-voltage systems, a dedicated circuit is run from the consumer unit with RCD protection and an outdoor isolator switch.
Fitting installation
Each light fitting is installed at its planned position — spike-mounted for borders, recessed for paths and patios, or bracket-mounted for walls and trees. All connections use IP-rated junction boxes or gel-filled connectors to prevent water ingress.
Testing and commissioning
The full circuit is tested for insulation resistance, earth continuity, and correct RCD operation. Light levels and positioning are adjusted. An Electrical Installation Certificate (EIC) is issued for mains-voltage work.
What's included
What's involved
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.

Every job is different — pricing depends on your property, location, and specific requirements. Describe what you need and a qualified electrician will quote you directly.
How long does it take?
One day for a simple 12V system with 4-6 fittings and short cable runs. One to two days for mains-voltage installations or larger schemes with 8-12 fittings, trenching across hard surfaces, or a new dedicated circuit.
Regulations & safety
Safety notice
Mains-voltage garden lighting is notifiable electrical work under Part P. It must be installed by a qualified electrician registered with a competent person scheme.
All outdoor electrical connections must use IP-rated enclosures suitable for the installation location. Standard indoor junction boxes will fail within months and create shock hazards.
Cables buried in the ground must be at the correct depth with warning tape — 500mm for mains-voltage SWA cable. Shallow burial risks cable damage from gardening tools.
Part P of the Building Regulations (Approved Document P)
New outdoor electrical circuits are notifiable work. Installation must be carried out by an electrician registered with a competent person scheme, or inspected and certified by Building Control.
BS 7671:2018+A2:2022 (IET Wiring Regulations), Section 714
Section 714 covers the specific requirements for outdoor lighting installations, including IP ratings for fittings and enclosures, cable burial depths, earthing, and protection against mechanical damage.
