What we install

Low Voltage Garden Lighting We Install

We do more than install lights. We design each lighting scheme around your garden, considering light placement, fitting combinations and long-term performance.

Spike Lights & Uplighters

We position 12V spike uplighters around trees, shrubs and planting, with flexible angles that can be adjusted as the garden develops.

Path & Bollard Lights

We install low-level 12V path lights and bollards to provide discreet, directional illumination along garden paths and walkways.

In-Ground Recessed Uplighters

We install flush-mounted fittings into suitable paving, gravel or soil for discreet illumination around tree bases and formal garden areas.

Step & Deck Lights

We integrate recessed lights into decking, steps and retaining walls to improve visibility with subtle, low-level illumination.

Micro LED Fairy Light Strings

We install outdoor-rated 12V fairy light strings for trees, hedges and decorative areas, creating a soft and attractive lighting effect.

Wall-Mounted 12V Lights

We install 12V wall lights on garden walls, steps and raised planters, using directional or spread-beam fittings where suitable.

Scheme

Create Different Lighting Effects Across Your Garden

Low voltage lighting gives us the flexibility to create different layers of illumination throughout an outdoor space. Rather than relying on one type of fitting, we can combine practical and decorative lighting to create a more considered result.

Practical Lighting

Used around paths, steps, entrances and other areas where visibility is important.

Accent Lighting

Used to draw attention to trees, planting, walls, structures and other features.

Ambient Lighting

Used to create a softer atmosphere around patios, seating areas, pergolas and outdoor entertaining spaces.

Feature Lighting

Used selectively to make particular elements of the garden stand out after dark. We consider how these different layers work together as part of the overall lighting design.

System comparison

Choosing Between 12V & 230V Garden Lighting

We use both systems depending on the application. 12V low voltage lighting suits most paths, borders and garden features, while 230V mains lighting is better suited to floodlighting, security, festoon and higher-output installations.

12V Low voltage

Best for paths, borders, and features

Very wide range of small, discreet fitting formats
Safe to reposition and extend without electrical work
Cable can be buried at shallower depth (150mm in conduit vs 500mm for SWA)
SELV — no shock risk from garden-side wiring
Total output limited by transformer capacity
Voltage drop limits run length without cable upsizing
Not appropriate for high-output floodlighting or festoon

230V Mains voltage

Best for floodlighting and festoon

Unlimited output — suitable for floodlights, festoon, and security
No voltage drop limitation on run length
Simpler for large or complex multi-zone schemes
All wiring must be carried out by a registered electrician
Cable must be SWA at 500mm minimum burial depth
Fittings cannot be moved or repositioned without electrical work
More disruptive to retrofit beneath established paving

Frequently Asked Questions

Is low voltage lighting suitable for every garden?

Low voltage lighting can be suitable for many outdoor applications, including paths, planting, trees, steps, decking and garden features. We assess the garden and proposed lighting before recommending the most appropriate system.

Can low voltage garden lights be added to an existing garden?

Yes. We can design lighting around an established garden, taking existing planting, paving, decking, walls and other features into account.

Can you install lighting around trees and planting?

Yes. We regularly incorporate tree and planting illumination into garden lighting schemes, using suitable fittings and positioning them to highlight the landscape without creating unnecessary glare.

Can low voltage lighting be installed in decking?

Suitable low voltage fittings can be incorporated into decking where the products and installation method are appropriate. We assess the decking and proposed fitting locations before installation.

Can I control my garden lighting from inside the house?

Depending on the system, we can incorporate suitable controls so the garden lighting can be operated from a convenient location inside the property.

Can you install garden lighting as part of a new landscaping project?

Yes. We can work with homeowners, landscape designers and other contractors to plan the electrical and lighting requirements alongside the wider garden project.
