Garden & Outdoor Lighting Installation Costs UK 2026 — What to Charge and Budget

Garden Lighting Costs by Scheme Size

The single biggest variable in a garden lighting quote is ambition. A handful of fittings on an existing outdoor socket is a different job from a fully zoned, app-controlled landscape scheme with trenched cable runs. Here's how the three broad tiers break down in the UK market.

Simple Set — Spike/Spot Lights or Wall Lights

The entry-level job: a small set of plug-in spike spotlights to uplight a tree or two, or a pair of wall lights either side of a door. These are usually low-voltage kits running off an existing outdoor socket, or simple mains wall lanterns wired into a nearby circuit. Minimal cable, no trenching, a few hours of labour.

• Plug-in spike/spot light kit (4–6 fittings) supplied and fitted: £150–£300
• Pair of mains wall lights fitted to existing circuit: £200–£400
• Typical labour: 2–4 hours

Most of the value here is in tidy cable management and getting the aim and beam angle right. Customers can buy the kit themselves, so your margin sits in the install and the design eye — make that the thing you sell.

Mid-Size Scheme — Path, Border and Feature Lights

The most common professional garden lighting job. Path or border markers, a few feature uplighters on planting or a wall, a properly sized transformer or driver, and a switched or timed circuit so the customer doesn't have to flick a socket on and off. Some cable will be run under borders or along edges, and the controls become part of the spec rather than an afterthought.

• Path, border and feature scheme (8–16 fittings) with transformer and timed/switched circuit: £500–£1,500
• Typical labour: 1–2 days for two people

This is the sweet spot for margin. The customer wants a finished result, not a parts list, and they'll judge you on the scheme's look at dusk — so quote it as a designed package with the controls and transformer sizing included, not a per-light price they can shop around.

Large Landscaped Scheme — Multiple Zones and Smart Control

The premium job: a designed scheme across a large or terraced garden with multiple lighting zones (entertaining area, planting beds, trees, water feature), decking and step lights, in-ground uplighters and smart app or scene control. Expect significant cable runs, trenching across lawns and beds, multiple drivers, and integration with the customer's home automation.

• Large multi-zone landscaped scheme with smart control: £2,000–£6,000+
• Typical labour: 3–6+ days depending on trenching and zone count

On these jobs the design and zoning is the product. Customers at this level have a landscape designer or a clear vision, and they care about scene presets, dimming and how the garden reads from inside the house at night. Price the design time and the smart commissioning as visible line items — they justify the premium.

Cost of Individual Elements

Whether you build up a quote from scratch or sense-check a package price, knowing the per-element costs keeps you from underquoting. These are typical supplied-and-fitted figures for the UK in 2026.

• Light fitting (supplied & fitted), per unit: £30–£120 depending on whether it's a budget spike spot or a quality brass in-ground or bollard fitting
• Low-voltage transformer / LED driver: £40–£150 supplied, plus fitting — size it to the total wattage with headroom (see below)
• Outdoor weatherproof socket (IP-rated, RCD-protected): £100–£200 each fitted
• Festoon / string lighting: £100–£400 supplied and hung depending on length and whether posts or catenary wire are needed
• Bollard lights: £60–£150 each fitted — popular for path edges and driveways
• In-ground uplighters: £50–£120 each fitted, more if a recessed sleeve and drainage need to be set into hard landscaping
• PIR floodlight (security/utility): £80–£200 each fitted depending on wattage and sensor quality

Quality varies enormously at every price point. Cheap die-cast aluminium fittings corrode within a few seasons; marine-grade stainless or solid brass fittings cost more up front but survive a decade-plus outdoors. For schemes you want to warranty, specify the better fittings and explain why in the quote — it protects you from callbacks.

Low-Voltage (12V SELV) vs Mains (230V) — and Part P

This is the most important technical distinction in garden lighting, and it decides who can legally carry out the work and what certification is required.

Low-voltage SELV systems (12V or 24V) run from a transformer or driver that steps mains down to a safe extra-low voltage. The cabling on the garden side is not notifiable in the same way as a mains circuit, the shock risk is far lower, and a competent landscaper can install the garden-side wiring once the transformer is fed from a properly protected supply. This is why most decorative garden schemes are low-voltage: they're safer, more flexible, and quicker to extend.

Mains 230V outdoor circuits are a different matter. Any new outdoor mains circuit is notifiable work under Part P of the Building Regulations in England and Wales. It must be RCD-protected, use IP-rated outdoor-grade fittings and enclosures, and the buried cable should be SWA (steel-wire armoured) or otherwise mechanically protected at the correct depth. This work must be carried out — or certified — by a registered electrician (NICEIC, NAPIT or equivalent), who will issue an Electrical Installation Certificate and notify Building Control. Skipping this isn't just a compliance risk; uncertified outdoor mains work can void insurance and cause problems at sale.

The practical takeaway for quoting: if your scheme is low-voltage off an existing certified outdoor supply, your costs are mostly fittings and labour. If it needs a new mains outdoor circuit or socket, build in the registered electrician's time, the SWA cable, the trenching to depth and the certification — that's often several hundred pounds before a single decorative light is fitted.

What Drives the Price

Two gardens with the same number of lights can quote hundreds of pounds apart. The variables that move the number are:

• Number of fittings: the most obvious driver — both supply cost and the labour to position, aim and connect each one.
• Cable runs and trenching: digging trenches across lawns, beds and especially hard landscaping (patios, paths, driveways) is the hidden cost. Lifting and relaying paving, or directional cabling under a patio, can dwarf the cost of the lights themselves.
• Transformer sizing: the transformer/driver must handle total wattage with headroom (typically load it to no more than 80% capacity). Long low-voltage runs also cause voltage drop, sometimes requiring a larger transformer or thicker cable — get this wrong and distant lights dim.
• Controls: a simple timer or photocell is cheap; smart/app control, scene presets, dimming and home-automation integration add fittings, commissioning time and skill.
• Access and ground type: a clear, soft-soil garden trenches in minutes; mature gardens with established roots, clay, or solid landscaping slow everything down. Awkward access for tools and spoil removal adds time too.

Running Costs

Running costs are rarely a barrier with modern lighting, and it's worth reassuring customers of this in the quote. Virtually all garden lighting today is LED, which draws a fraction of the power of the old halogen spike lights. A typical low-voltage LED fitting might draw 2–5W, so even a sizeable scheme of fifteen fittings running for a few hours each evening costs only a few pounds a month on a standard 2026 unit rate.

Timers and photocells trim this further by ensuring lights only run when wanted, and dimming on smart schemes reduces both consumption and lamp wear. The headline point for customers: the upfront install is the cost — the lighting itself is cheap to run and LED fittings typically last many years before replacement.

Design Tips and Maintenance

A well-designed scheme is what separates a memorable garden from a runway of evenly-spaced spotlights. A few principles that lift the result and the price you can charge:

• Layer the light: mix uplighting on trees and walls, soft path/marker lighting and feature accents rather than flooding everything evenly. Contrast is what makes a garden look designed.
• Hide the source: conceal fittings in planting or recess them so the eye sees the lit object, not the lamp. Glare from a badly-aimed spot ruins the effect.
• Warm colour temperature: 2700–3000K reads as inviting in a domestic garden; cooler white can look harsh and clinical.
• Zone it: separate switching or scenes for entertaining areas, planting and security lets the customer set a mood rather than all-or-nothing.
• Plan for growth: plants spread and trees grow, so leave aiming adjustment and slack in cable runs.

On maintenance, set expectations early. Lenses need an occasional wipe, in-ground fittings need keeping clear of leaf litter and standing water, and planting may need to be trimmed back off fittings each season. Offering an annual check-and-clean visit — re-aiming lights, cleaning lenses, checking connections and the transformer — is a tidy recurring service worth £80–£200 a visit and keeps schemes looking their best.
