Exterior Lighting near you

Section 79(1) of the Environmental Protection Act 1990 lists the matters that constitute statutory nuisances, and artificial light has its own paragraph: section 79(1)(fb) covers artificial light emitted from premises so as to be prejudicial to health or a nuisance. It sits separately from the smoke, fumes, dust and noise limbs, and it was added to the Act rather than being there from the start. Domestic premises are squarely within it.

There is an exemption list and it is narrow. Section 79(5B) disapplies the artificial light paragraph for airports, harbour premises, railway premises, tramway premises, bus stations and their associated facilities, public service vehicle operating centres, goods vehicle operating centres, lighthouses and prisons. A house, a garden, a drive and a private car park are not on that list.

Once a local authority is satisfied that a statutory nuisance exists or is likely to occur, section 80 requires it to serve an abatement notice, normally on the person responsible. The recipient has 21 days from service to appeal to a magistrates' court. Contravening the notice without reasonable excuse is an offence, and for premises other than industrial, trade or business premises the penalty on summary conviction is a fine not exceeding level 5 on the standard scale, together with a further daily fine equal to one-tenth of the greater of £5,000 or level 4 on the standard scale for each day the offence continues after conviction.

There is no statutory lux limit for a domestic floodlight, which is why complaints so often turn into arguments about opinion. What environmental health officers and lighting consultants reach for instead is the Institution of Lighting Professionals' Guidance Note 1, in its 2021 revision - GN01/21, The Reduction of Obtrusive Light - which sets out limits by environmental zone.

The zones run from E0, protected dark skies, through E1 natural dark, covering relatively uninhabited rural areas, national parks and areas of outstanding natural beauty; E2 rural, low district brightness; E3 suburban, medium district brightness, which is where most British houses sit; to E4 urban, high district brightness. The guidance gives limits for light intruding into windows, measured as illuminance in the vertical plane, and tightens them sharply after curfew: in E1 the figures are 2 lux before curfew and less than 0.1 lux after; in E2, 5 lux and 1 lux; in E3, 10 lux and 2 lux; in E4, 25 lux and 5 lux.

Two things follow for a homeowner. First, the same floodlight can be entirely reasonable in a town centre and indefensible in a village, so where you live is part of the specification. Second, the curfew concept - a stricter limit late at night - is the single cheapest way to defuse a complaint, because a timer or a shorter PIR duration costs almost nothing and removes the part of the problem that people actually mind.

Two protections matter outside and they are frequently confused. Ingress protection is about the fitting: the IP code describes how well an enclosure keeps solid objects and water out, and an exterior position facing the weather needs a rating chosen for driving rain, not for a sheltered porch. Residual current protection is about the circuit: a 30 milliamp residual current device disconnects fast enough to give additional protection if a fault puts a person in the path.

BS 7671 pushes in the same direction from two sides. Since the 18th Edition, regulation 411.3.4 has required all luminaires in domestic premises on an alternating current final circuit to have additional protection by a 30 milliamp RCD, which now captures the outside lights as well as the inside ones. Separately, additional protection by a 30 milliamp RCD is required for mobile equipment with a rated current not exceeding 32 amps intended for use outdoors - the rule that catches the mower, the pressure washer and everything else plugged in outside.

The practical checks are unglamorous. Is the cable entry into the fitting at the bottom or sealed, rather than open to the sky? Is the gland the right one for the cable? Is the fitting screwed to something that will still be there in ten years? And does the circuit it is on actually have RCD protection, or was the light added to a lighting circuit that predates the requirement?

Water is the usual cause of failure, and it rarely arrives the way people expect. It comes in at the cable entry, at a gasket that perished in ultraviolet light, at a lens seal cracked by thermal cycling, or up from below when a fitting is mounted with its opening facing upward. Once inside, it corrodes terminals, tracks across a driver and eventually operates the RCD, which is the point at which most people notice.

Integrated LED fittings change the failure mode. There is no lamp to replace, so when the driver goes the fitting goes, and a cheap unit that has been exposed for two winters may not be worth opening. That is an argument for buying on the quality of the enclosure and the gasket rather than on lumens per pound, because the light output is the part least likely to disappoint.

False triggering has a small set of causes: the sensor seeing a warm surface as it cools, heat plumes from a flue or a vent, moving foliage in front of the detection zone, traffic on a road the zone reaches, and animals. Adjusting the sensitivity, tilting the sensor head down, masking part of the lens and cutting the vegetation back solve most of it. A light that triggers all night is not just irritating; it is exactly the pattern that turns into a complaint under section 79(1)(fb).

Where the power is coming from decides most of it. A fitting beside an existing outside light is a short job; a floodlight on a gable with no supply nearby means a cable route, possibly a new circuit from the consumer unit, and possibly a scaffold tower or a ladder job at height. Wall construction matters - drilling and fixing into stone, render or cavity brick are not equivalent - and so does the number of fittings, the controls, and whether you need switching from more than one place. If the circuit has no residual current protection, that will appear in the quotation too, and it should.
