UK Garden Lighting Cost Guide 2026

Planning to add garden lighting and wondering what it’ll really cost? Whether you want subtle path lights, dramatic feature lighting, or a full security setup, the final bill can vary a lot depending on cable runs, transformer size, and the amount of labour involved.

How Much Does Garden Lighting Cost in the UK?

Most UK garden lighting projects cost £800–2,500 for a small to medium garden, while larger or more complex installs can reach £3,500–7,000+. Simple solar-only upgrades may be cheaper, but wired lighting with transformers, trenching and professional installation delivers the best reliability and finish.

Garden lighting sits in the same broad category as other outdoor improvement Cost Guides, but it often overlaps with Lighting & Irrigation work, especially if cables need to run alongside planting areas, patios, or existing hard landscaping. If you’re also reworking a terrace or path, it may make sense to coordinate the job with Garden paving cost in the UK: 2026 guide so the lighting layout matches the finished surface.

What Affects the Cost of Garden Lighting?

The final price is shaped by the size of the garden, the number of fittings, the type of lighting, and how difficult it is to route power safely. A small patio with a few low-voltage lights is much cheaper than a long garden with buried cable runs, multiple circuits and remote switch points.

Here are the main cost drivers:

1. Garden size and layout
A compact garden might only need 3–6 lights, while a large space could need 10–20+ fixtures. The more zones you want to illuminate, the higher the material and labour cost.

2. Cable runs and excavation
Buried armoured cable, conduit, and trenching add time and materials. Expect longer cable runs to increase costs by £150–600 or more, depending on distance and ground conditions.

3. Transformer and control gear
Low-voltage systems need a transformer, usually costing £60–250 depending on capacity and quality. Timers, dusk-to-dawn sensors, and smart controls can add £40–300.

4. Ground surfaces and access
Running cables under lawns is easier than cutting through slabs, gravel, or established Patios & Paving. If lighting must be installed around raised planters, retaining edges, or feature areas, labour can rise noticeably.

5. IP rating and fixture quality
Outdoor-rated fittings are essential. Basic path lights may cost £20–60 each, while premium stainless steel, brass, or designer fixtures can cost £80–250+ each.

6. Electrical upgrade needs
If your consumer unit, outdoor socket arrangement or RCD protection needs updating, that can add £200–900 depending on the work required. In older homes, this is a common surprise cost.

7. Related garden works
If the project also includes posts, wall mounts, or lighting integrated into structures, the cost can rise. That’s particularly true around Garden Buildings, pergolas, sheds and summerhouses, where safe wiring routes and weatherproof fittings matter.

Average Price Breakdown by Lighting Type

Different garden lighting types come with very different price points. Below is a practical breakdown of typical UK pricing for supply and install.

Path lighting
Path lights are one of the most common choices for safety and ambience. For a small run of 4–6 lights, expect £350–900 installed. Mid-range projects with better fixtures and longer cable runs often cost £900–1,800.

Feature lighting
Feature lighting highlights trees, planting, water features or architectural details. Uplighters, spotlights and narrow-beam fittings usually cost more than basic path lights because of positioning and aiming. A typical feature-lighting scheme costs £500–1,500 for smaller gardens and £1,500–3,500+ for larger designs.

Security lighting
Motion-sensor security lights generally cost £180–500 per fitting installed, depending on power source and complexity. A small security setup with 1–3 lights may total £300–1,200, while a wider perimeter scheme can cost £1,200–2,500.

Deck, wall and step lighting
Low-level accent lighting around steps, decking, raised edges and seating areas often costs £300–1,200 for small installations. More extensive schemes that tie into landscaping or built features can reach £1,500–4,000.

Solar garden lighting
Solar lights are the cheapest upfront option, but they usually provide less reliable performance. DIY solar kits can cost £50–300, while better-quality solar setups may reach £300–800. They’re useful for light ambience, but not ideal where dependable year-round lighting is needed.

Example total budgets
Small garden: £800–1,500 for a few path and feature lights
Medium garden: £1,500–3,500 for mixed path, feature and security lighting
Large garden: £3,500–7,000+ for multiple zones, premium fittings and longer cable runs

If your scheme is being planned alongside planting, water features or a full outdoor redesign, the cost can sit closer to broader Garden Services projects rather than a simple electrical upgrade. For example, a lighting scheme around a pond or focal feature may be best planned at the same time as works covered in our UK Garden Water Feature Cost Guide.

Labour Costs for Garden Lighting Installation

Labour is often a major part of the bill, especially when the electrician needs to dig, route cables and test multiple circuits. In the UK, electricians commonly charge £250–450 per day, with smaller jobs often quoted as a fixed project fee.

Typical labour costs include:

Basic installation
For a straightforward setup with existing outdoor power and easy access, labour may be £250–700.

Moderate installation
If trenching, transformer mounting and multiple fittings are needed, labour is more likely to be £700–1,800.

Complex installation
For larger gardens, difficult ground, or lighting integrated into structures and seating areas, labour can rise to £1,800–3,500+.

Additional electrician charges
Site visits, fault finding, upgrading outdoor circuits, and certification may be billed separately or built into the quote. Always confirm whether VAT, testing, and materials are included.

As a rule, more neatly finished installations cost more up front, but they tend to last longer and need less maintenance. That matters if you want a reliable setup for dark winter evenings and year-round use.

How to Save Money and Get the Best Value

There are several smart ways to keep costs under control without compromising safety or quality. The biggest savings usually come from simplifying the design and reducing the amount of ground work required.

Keep the layout focused
Instead of lighting every corner, concentrate on the areas you use most: paths, steps, entrances, seating spaces and one or two feature points. A well-planned smaller scheme often looks better than an over-lit garden.

Use low-voltage lighting
Low-voltage systems are popular for domestic gardens because they’re flexible and generally cheaper to extend. They’re especially useful for schemes with path lights, uplighters and focal points.

Install lighting at the same time as other works
If you’re already carrying out landscaping, patio work or building a structure, installing lighting at the same time can reduce repeat labour. This is especially useful around Garden Buildings, seating areas, or newly laid features.

Choose mid-range fittings
You don’t need to buy the most expensive fixtures to get a good result. Mid-range brass, aluminium or stainless steel fittings often offer the best value for long-term outdoor use.

Ask about trenching strategy
Running cables in a planned route, rather than adding them one by one, can save labour. If you have borders or beds that are already being improved, coordinating with Garden Services can reduce disruption.

Compare quotes carefully
A cheap quote might exclude transformer upgrades, weatherproof junction boxes, trenching, or certification. Look for itemised pricing so you can compare like-for-like.

Consider future expansion
If you think you may add more lights later, ask for a transformer and cable setup that can handle additional fittings. It may cost slightly more now, but it avoids expensive rework later.

For gardens that combine lighting with planting, structures and edging, it can be worth planning the whole scheme together. That way, the electrical design supports the final layout rather than getting squeezed in at the end.

In most UK gardens, a professional lighting installation will sit somewhere between £800 and £3,500, with larger or premium projects costing more. To get the best value, request at least three detailed quotes, check that the contractor is qualified to carry out outdoor electrical work, and make sure they include materials, labour, certification, transformer sizing and any trenching or cable runs before you commit.
