Garden Lighting Use Planning Checklist

Write down every reason anyone in the household steps outside after dark, including taking bins out, letting a pet out and coming home with shopping.

The unglamorous trips are the ones that need light most, and they are almost never the ones a scheme is designed around.

Note which of these trips are made by children, by older relatives or by someone carrying something in both hands, since each changes what the lighting has to do.

Who is walking the route matters more than how attractive the route looks lit.

Be honest about whether you actually sit outside once it is dark, or whether you mainly look at the garden through the window from a lit room.

Looking at a garden and being in it call for very different lighting, and most households do far more of the former.

Note how late the garden is used and by whom, and whether anything is still running once the household has gone to bed.

Late-running lighting is where complaints and wasted running come from, and it is easy to think about now.

Consider how differently the garden is used when it is dark by late afternoon compared with the height of summer, and note which lights matter in each case.

In the darker part of the year the garden is crossed rather than occupied, which points at routes rather than features.

Walk each route you listed in the dark with a torch, and mark the points where you slowed down, reached out or looked at your feet.

The places you hesitate are the places that need light, and they are obvious on a night walk and invisible on a plan.

Note every step, kerb or change of level on each route, including the single step at a threshold that people forget is there.

A single unexpected step is the most common trip point in a garden, and it rarely appears on anyone list of features.

Note where you have to find a latch, a keyhole or a bolt in the dark, and whether your own body would be between the light and your hands.

Standing in your own shadow at a gate is a very common outcome of lighting positioned for appearance.

Check the side passage and the bin store, which are often the darkest parts of a property and the ones used most often after dark.

These are working routes rather than display areas, and they usually get left out of a garden lighting brief entirely.

Follow the walk from where a car is parked or a taxi stops to the front door, and note where a visitor would be unsure of the surface underfoot.

Guests use this route without knowing the garden, so it needs to work for someone who has never walked it before.

Note that with lights on indoors and nothing outside, the glass becomes a mirror, and record which rooms this affects most in the evening.

This is often the real reason a garden feels closed off after dark, and it points towards a little light in the depth of the garden.

Check whether any proposed fitting would sit in direct line of sight from a chair indoors, so you would see the source rather than what it lights.

A visible source dominates the view and makes everything around it look darker than it is.

Note that lighting one area brightly makes everything beyond it read as a black wall, and decide whether that suits the way you use the garden.

Contrast, not brightness, determines how far a garden appears to extend after dark.

Consider which surfaces would be wet or shiny at night, and how light landing on them might bounce back towards the house or a seating area.

Wet paving and water reflect far more than dry ground, and the effect is not obvious when a scheme is planned in daylight.

If you are considering lighting a tree from below, ask a lighting professional and a qualified arborist what that means for the tree and for anyone looking towards it.

Uplighting is visually striking but has consequences for glare and for the tree itself worth raising early.

Anything involving a fitting placed at, in or near a tree should be discussed with both a lighting professional and a qualified arborist before it is planned.

Stand at your boundary and note which neighbouring windows face your garden, and which of them are bedrooms if you can tell.

Light reaching a bedroom window is the most common cause of a neighbour dispute over garden lighting.

Consider where light from each proposed position would land beyond your own boundary, including a shared path, a lane or a garden behind you.

Spill is easy to plan out at the design stage and difficult to correct once fittings are set.

Note whether anything moving outside your boundary, such as passing traffic or a neighbouring cat, could repeatedly trigger a sensor you are considering.

A sensor that fires all evening is worse for everyone than a light that simply stays off.

Ask a lighting professional or ecologist what your lighting intentions might mean for wildlife using the garden, and record what they tell you.

This is increasingly part of a garden lighting conversation, and it is a question rather than something to decide alone.

Any question about lighting and wildlife belongs with a qualified ecologist or lighting professional, and any local requirements must be confirmed with the local authority.

Confirm with your local authority whether anything applies to external lighting at your property, particularly if you are in a sensitive or protected setting.

Requirements vary by location and by property type, so this can only be answered locally.

Whether any restriction applies to external lighting at your property must be confirmed with your local authority rather than assumed either way.

Decide whether you would rather mention the plan to a neighbour before the lights appear, and note what you would want to say.

A short conversation beforehand is far easier than an awkward one afterwards, and it sometimes changes a position for the better.

Note where you would be standing when you want the garden lights on, and where you would be standing when you want them off.

These are often different places, and a scheme switched only from one of them ends up left on.

Decide which lights you would want on together, such as a route on its own, so that stepping outside briefly does not light the whole garden.

Grouping is the single thing that most affects whether garden lighting is used comfortably or avoided.

Consider which parts of the garden you would want to respond automatically and which you would always want under your own control.

Automatic control suits working routes, while seating areas usually want deliberate switching.

Write down who is responsible for turning outdoor lighting off at the end of an evening, and whether that person is always the last one in.

Naming a person makes the answer honest, and it usually changes the case for timers or sensors.

Ask what happens to any timed control when the clocks change or the darker months arrive, and record how it would be adjusted.

Timed controls that nobody knows how to adjust drift out of step and are then abandoned.

Consider whether you would be standing in the rain while operating anything outdoors, and whether the control position accounts for that.

Controls placed for neatness rather than for use are a common frustration in wet weather.

Note any existing outdoor socket, fitting or supply and where it appears to come from, then leave the assessment of it to a qualified electrician.

What already exists shapes what is straightforward, but only a professional can say what condition it is in.

Any assessment of existing outdoor electrical work, and all new outdoor electrical work, is for a qualified electrician alone.

Sketch roughly where cables would have to travel from the house to each lit area, and note what they would cross on the way.

A route crossing a lawn, a patio or a planted bed has very different implications, and it is worth knowing before the design is fixed.

Note any drain, cover, meter, water pipe or service run you already know about, and hand that information to whoever is planning the work.

What the owner knows about buried services is genuinely useful information and is often never asked for.

Any excavation near buried services must be planned by qualified professionals with the relevant utility information, never on the basis of an owner sketch alone.

Ask in what order lighting work and hard landscaping should happen, so that cable routes are not being cut into finished surfaces afterwards.

Sequencing is the difference between a tidy installation and a repaired surface, and it has to be raised early.

Consider whether you might want to light another area later, and ask what could be allowed for now while the ground is already open.

Allowing for later additions while excavation is happening is far simpler than reopening the garden.

Ask the electrician and the supplier to confirm that anything you like is intended for the position you want it in, rather than judging from a photograph.

Outdoor positions vary a great deal in exposure, and suitability is not something to determine from an image.

Whether a particular fitting suits a particular outdoor position must be confirmed by the supplier and a qualified electrician for your specific conditions.

Accept that planting will grow around and over fittings, and note which proposed positions would be swallowed first as beds fill out.

Buried and low fittings disappear into planting sooner than owners expect, which is when a scheme quietly stops working.

Check whether you could reach each fitting to clean it or change a lamp without standing in a bed, on a wall or on something unstable.

Access decides whether maintenance happens, and unreachable fittings stay dirty or dark.

Note that outdoor lenses collect soil splash, leaf debris and film, and decide who would wipe them and how often that is realistic.

A dirty lens dims a fitting dramatically, and it is usually mistaken for a fault.

Consider what happens where mowing or edging meets a fitting or a spike, and note which positions would be at risk from routine garden work.

Damage from routine maintenance is one of the more common causes of a garden light failing.

Ask the supplier what happens if a fitting or a lamp fails, and record the answer before choosing anything you would struggle to replace.

Replaceability matters more outdoors than indoors because fittings work harder in the weather.

Ask for a written record of what was installed and where any cables run, and keep it with your property papers for whoever works in the garden next.

The next person to dig in the garden needs this, and it is almost never handed over unless asked for.

Ask the qualified electrician what documentation they will provide on completion, and keep it; it may be needed by anyone working on the garden later.

Take a torch out after dark and hold it where each fitting is proposed, then look at the effect from indoors and from the seating area.

A rough torch test answers more questions in one evening than any amount of daytime discussion.

Stand at the far end of the garden and look back towards the house, noting what is already lit from indoors before you add anything.

Spill from indoor lighting often already covers more of the garden than owners realise.

Photograph the garden at night as it is now, so you have a record of the starting point to compare against later.

Night photographs make dark holes and glare far more obvious than the eye does at the time.

Ask someone to walk each route while you watch from indoors, and note where they disappear from view or become a silhouette.

Watching someone else use the garden shows up problems that walking it yourself does not.

Where you can, leave a temporary arrangement in place over several evenings and note what irritated you, rather than deciding on a single night.

Irritation with glare or a badly placed source usually takes several evenings to become apparent.
