Outdoor & Garden Lighting Cost UK 2026
A professionally installed garden lighting scheme costs £300–£1,500 for most homes: £50–£150 per fitting installed on an existing circuit, and £200–£500 for the new outdoor circuit bigger schemes need. Outdoor circuits are notifiable under Part P — this is registered-electrician work.
Outdoor lighting cost by job — 2026
Installed prices, fittings included at mid-range spec. Designer fittings move totals up faster than labour does.
| Job | Typical installed cost | Includes | Notes |
|---|---|---|---|
| Security floodlight (PIR) | £80–£250 | Fitting, sensor, connection | The single most-bought job |
| Wall and porch lights (each) | £50–£150 | Fitting and connection | On an existing circuit |
| Garden lighting scheme (4–8 lights) | £500–£1,500 | Fittings, cable runs, controls | Beds, paths and trees |
| New outdoor circuit + RCD | £200–£500 | Armoured cable, protection, certificate | The foundation for anything bigger |
| Low-voltage plug-and-play set | £100–£400 fitted | Transformer and spike lights | The no-notification route |
| Smart controls | +£80–£300 | App scheduling, PIR integration | Rides the home automation wave |
Indicative 2026 UK prices, compiled from published installer pricing (Checkatrade, MyJobQuote, MyBuilder and BookaBuilder cost guides, August 2026). BestBuilders has no quote history in this category yet, so treat these as a budgeting guide and confirm against three written quotes.
What changes the cost
| Cost factor | Typical impact | Why it matters |
|---|---|---|
| Cable runs and trenching | the labour | Armoured cable buried at depth along a garden is digging first, electrics second |
| New circuit or existing | £200–£500 difference | A couple of wall lights tee off what exists; schemes need their own protected circuit |
| Part P notification | built into honest quotes | New outdoor circuits are notifiable Building Regulations work - a registered electrician self-certifies, anyone else means building control fees |
| Fitting spec | the runaway variable | Spike lights are £20; corten and brass designer fittings are £150+ each before wiring |
| Mains vs low voltage | the shortcut decision | 12V plug-in systems avoid notification and trenching at the cost of brightness and permanence |

| Scotland | £450–£1,350 | −10% |

| Northern Ireland | £420–£1,280 | −15% |
Getting it priced properly
1. Decide mains or low-voltage first
A 12V transformer kit is a weekend job and legally simple. Mains in the garden is better light and a notifiable installation - the fork decides everything after it.
2. Get the certificate
A new outdoor circuit should come with an Electrical Installation Certificate and a Part P notification. No paperwork, no sale when you move.
3. Light less than you think
Gardens want pools of light, not floodlit pitches - a 4-6 fitting scheme usually beats a 10-fitting one, and costs less to run and fit.

Outdoor circuits are notifiable work
Garden lighting is where a lot of DIY comes unstuck, because a new outdoor circuit is notifiable under Part P of the building regulations. That means it has to be installed or signed off by a registered electrician and certified — not for the paperwork's sake, but because the certificate is the record that the work is safe, and it is what a buyer's solicitor asks for later. Adding a few fittings to an existing, properly protected circuit at £50–150 each is the simpler job; it is the new £200–500 circuit that triggers the requirement.
Ask any electrician whether they are registered with a Part P scheme (NICEIC, NAPIT or similar) and will issue a certificate — it is a fair thing to check, and a good one expects the question. Price a fitting count or a full scheme with the outdoor lighting calculator, and if it is going in as part of a wider job, the electrical hub covers the rest of the work.
Outdoor lighting — frequently asked questions
Around £50–£150 per fitting on an existing circuit, £500–£1,500 for a 4–8 light scheme, plus £200–£500 if a new outdoor circuit is needed.
New outdoor circuits are notifiable under Part P of the Building Regulations - registered-electrician work. Swapping a like-for-like fitting or using a 12V plug-in kit is not notifiable.
A low-voltage plug-and-play kit: £100–£400 fitted, no trenching, no notification. The trade is brightness and permanence - mains schemes light trees, low voltage lights paths.
They are the outdoor job buyers notice: a PIR floodlight at £80–£250 installed is among the cheapest visible improvements a house exterior can buy.
