How it works

1

Survey and positioning

Your electrician assesses the property to identify the best locations for security lighting — typically above entry points, driveways, side passages, and rear gardens. They consider detection range, mounting height, and aiming angles to maximise coverage while avoiding light spill into neighbouring properties.

2

Fitting selection

Based on the survey, the electrician recommends suitable fittings — PIR sensor floodlights for motion detection, dusk-to-dawn photocell lights for all-night illumination, or combined units. LED fittings are standard, offering bright output with low running costs and long life.

3

Circuit assessment

The electrician checks whether the lights can be connected to an existing circuit via a fused spur, or whether a new dedicated circuit is needed. If a new circuit is required, this is notifiable work under Part P.

4

Installation and wiring

Fittings are mounted at the correct height (typically 2-3 metres) and connected to the supply. External cable runs use suitable outdoor-rated cable in conduit. All connections are made with IP-rated enclosures.

5

Testing and adjustment

The circuit is tested and the PIR sensitivity, detection range, timer duration, and dusk-to-dawn threshold are adjusted. The electrician walks the detection zone to verify coverage and checks that light spill does not affect neighbouring properties.

What's involved

Security lighting is one of the most effective deterrents against break-ins — a well-positioned PIR floodlight can make the difference between a target and a pass. Installation covers selecting the right fittings (PIR motion sensor, dusk-to-dawn photocell, or manual switch), positioning for maximum coverage without causing light nuisance to neighbours, and connecting to a suitable circuit with RCD protection. Most single-light installations take 2-3 hours; multi-light setups around a property take half a day.

If the security light is connected to an existing circuit via a spur, it may not require Part P notification — but a new outdoor circuit is notifiable work. Regardless of notification requirements, outdoor electrical work must comply with BS 7671 Section 714 and all fittings must be IP-rated for their location. Incorrect installation of PIR floodlights is one of the most common causes of neighbour disputes over light nuisance, which is covered by the Environmental Protection Act 1990. Professional installation ensures correct positioning, aiming, and sensitivity adjustment.

Regulations & safety

Safety notice

Outdoor electrical connections must use IP-rated fittings and enclosures. Indoor-rated equipment exposed to weather will fail and create shock hazards.

Security lights should be mounted at 2-3 metres height and aimed downward. Lights aimed horizontally or at neighbouring properties can cause light nuisance — a legal issue under the Environmental Protection Act 1990.

If a new outdoor circuit is required, this is notifiable work under Part P and must be carried out by a registered electrician.

Part P of the Building Regulations (Approved Document P)

A new outdoor circuit for security lighting is notifiable work. Adding a light to an existing circuit via a fused spur is typically non-notifiable, but must still comply with BS 7671.

BS 7671:2018+A2:2022 (IET Wiring Regulations), Section 714

Section 714 governs outdoor electrical installations, including IP ratings for fittings, cable protection, and earthing requirements for security lighting.

Environmental Protection Act 1990 — Statutory Nuisance (Light)

Artificial light from premises that is prejudicial to health or a nuisance can be treated as a statutory nuisance by local councils. Security lights must be positioned and aimed to avoid unreasonable light spill into neighbouring properties.

What to expect

The single biggest complaint about security lighting is false triggers — cats, foxes, swaying branches, and passing cars. Your electrician can adjust PIR sensitivity and detection zones, but positioning is key. Mount the sensor to detect movement across the detection zone (not towards it) for the most reliable triggering.
LED security lights draw very little power (typically 10-30W), so running costs are minimal — even an all-night dusk-to-dawn light costs under £10 per year. This makes photocell dusk-to-dawn lights a practical option for constant low-level illumination alongside PIR-triggered floodlights.
Light nuisance is a genuine legal issue. Local councils can serve abatement notices under the Environmental Protection Act. Position lights to illuminate your property, not your neighbour's bedroom. Adjustable cowls and shields can help limit spill.
Smart security lights with Wi-Fi connectivity can send phone alerts on motion detection and integrate with CCTV cameras. These cost more upfront (£50-150 per fitting vs £20-50 for basic PIR floods) but add significant functionality.

Frequently asked questions

Do I need an electrician to install a security light?
If the light is being connected to a new outdoor circuit, yes — this is notifiable work under Part P and must be done by a registered electrician. Even for a simple replacement or spur connection, professional installation ensures the correct IP rating, cable type, and RCD protection are used for outdoor work.
What is the difference between PIR and dusk-to-dawn security lights?
PIR (Passive Infrared) lights activate when they detect movement — ideal for alerting you to activity. Dusk-to-dawn lights use a photocell to stay on from sunset to sunrise, providing constant illumination. Many homeowners use both: dusk-to-dawn for low-level ambient light and PIR floodlights for bright motion-activated coverage.
How do I stop my security light triggering on cats and foxes?
Reduce the PIR sensitivity setting, narrow the detection zone, and adjust the mounting angle. Most PIR sensors have adjustable sensitivity and can be aimed to ignore ground-level movement. Mounting the sensor higher (3 metres) and angling it down helps reduce false triggers from small animals.
Can my neighbour complain about my security light?
Yes. Under the Environmental Protection Act 1990, artificial light that is prejudicial to health or a nuisance can be treated as a statutory nuisance. Your local council can investigate and serve an abatement notice. The key is to position and aim lights so they illuminate your property without causing unreasonable light spill.
How bright should a security light be?
For a domestic PIR floodlight, 1,000-2,000 lumens is typically sufficient for a driveway or rear garden. Anything above 3,000 lumens is likely to cause glare and light nuisance. LED fittings give more usable light per watt than halogen, so a 20W LED floodlight (around 1,800 lumens) is usually plenty.
