Most light trails are drawn in the summer, in daylight, on a site plan. They get built in November, in the dark, on ground that has been rained on for a fortnight, by a crew carrying heavy things down a path that looked wider on paper. Christmas light trail planning lives in that gap. The creative idea is the easy part. The site decides whether it survives a wet field after dark.
We install and hire out lighting for venues, estates and visitor attractions, so the questions below are the ones we end up asking on a first site visit.
Christmas light trail planning starts with a walk, not a drawing
A trail is a footpath that thousands of people will use, after dark, in the worst weather of the year, for several weeks. Grass that looks solid in September will not be grass by the second week of December.
Health and Safety Executive (HSE) guidance on venue and site design tells organisers to find out the load-bearing capacity of the ground for any intended structure, and to check ground conditions at any structural anchoring points. It also asks you to consider site topography and how the site copes with extreme weather like flooding, because that may affect your site design. On a woodland or parkland route that is the difference between an arch that stands for six weeks and one that moves in the first gale.
So walk the whole route in bad weather before you commit to it. Note where water sits, where the ground falls away, and where the surface changes from tarmac to grass to mud. Then decide what needs trackway or matting, and agree who is putting the ground back afterwards. Reinstatement is the easiest thing to leave out of a brief and the thing a landowner remembers longest. The same reasoning applies to anything heavy standing on soft ground, as we covered for outdoor LED screen hire.
Power is a route decision, not the last job on the list
Lighting a trail means running a temporary electrical installation across a site that was never wired for one. Where the distribution points can sit, and how far a cable has to travel to reach a feature, shapes the route as much as the trees do.
HSE guidance on electrical safety at events is unusually specific here, and almost nobody in festive lighting cites it. Cables should be selected and specified to withstand any unusual environmental or adverse weather conditions, and routed to minimise tripping hazards or potential mechanical damage, in a position that allows them to be safely installed and removed. Cable ramps or similar can protect cables running overground across route ways. Where a cable runs overhead, a height of not less than 5.8m is advisable so most vehicles can pass beneath it, with advisory notices displayed in both directions. Cable joints should not be left underground. Anything exposed to rain needs suitable and sufficient covers, enclosures or shelters.
That is a design constraint, not a compliance exercise. Every metre of cable between a distribution point and a feature has to be protected, walked past in the dark by a family in wellingtons, and found again in January.
The season is set by darkness, and darkness has a date
A light trail only exists when it is properly dark. In the UK the clocks go back one hour at 2am on the last Sunday in October, which is roughly when an early evening admission slot starts to work at all. Before that, a trail opening at five o’clock is a walk in the gloom. Darkness also caps the operating window every night, and that window is shorter than most first drafts assume.
The date drives the schedule backwards. The build has to be finished and tested before the first visitor arrives, and testing means being on site at night, more than once, because a feature that looked right on a laptop looks different through trees. Seasonal lighting stock is committed for a whole season rather than a weekend, and the distinctive pieces go first, so any decision with equipment attached has to be made months earlier than feels necessary.
Capacity is set by the narrowest part of the path
The same HSE guidance is blunt about capacity: the capacity of a venue depends on the available space for people, and the limiting factors are often the emergency exits and the audience circulation capacity of the site. It warns against creating pinch points where channelling the public could lead to dangerous overcrowding during an emergency, and notes that extra space may be needed around structures.
On a trail the narrow part is usually a gate, a bridge, or the crowd in front of the feature everyone wants a photograph of. Timed entry helps, but only if the interval is set by the slowest section of the route. Walk the route at the pace of a family with a pushchair and a five year old who stops at everything, and time it. That figure, not the length of the route in metres, is what your admission slots have to respect.
Somebody has to be responsible, and on your land it is you
The HSE is direct about roles at events: the organiser has prime responsibility for the health and safety of workers, the audience and contractors. If the trail is on your site, that is you, whoever is holding the ladder. The same guidance says a contractor should be able to provide evidence of a trained workforce and the competence of key staff for the work they will do.
So ask for it. A supplier who produces that quickly is telling you something, and so is one who cannot. Splitting a trail between a lighting company, a power contractor and a ground protection firm hands every gap between them back to you, in the month you have the least attention to spare. One supplier holding the design, the equipment, the crew and the schedule is a shorter list of people to chase, which is the argument for a single technical partner on a job that runs for weeks.
The handover matters more than on a one night event
A conference ends and the crew take it away. A light trail runs for weeks, and your team runs it, not ours. Somebody local has to switch it on, notice when a section has gone out, and know who to call on a Saturday evening.
One of our published testimonials, from Louis Kirby, describes the part of the job that settles this. The technical team who set up and later de-rigged the equipment, meaning took it down and cleared the site, were knowledgeable and helpful, and James stayed on site to check everything worked and demonstrated the kit before leaving. On a seasonal installation that demonstration is the handover. Ask for it, and ask what happens on the night a section fails.
What to have ready before you brief anyone
- A route you have walked in the dark and in the wet, with the wet parts marked on the plan.
- Where the existing power is, what it can support, and where a generator could stand without being heard from the path.
- The dates the site is free for the build and the take down, and anything else booked there in between.
- The narrowest point on the route, measured rather than estimated.
- Who owns the ground, and what condition it has to be handed back in.
- Who at your end can make a decision at four o’clock on a Friday in November.
None of that is the creative brief, and that is deliberate. Specifying features before anyone understands the site produces features that cannot go where the drawing puts them.
Talk to us about your trail
We supply audio visual (AV) equipment, lighting, rigging and staging from one source, with project management and technicians, and we deliver nationwide from our base in Manchester. If you are planning a trail for this season or the one after, the useful first conversation is about the site, not the equipment list.
Send us your route and your dates through our contact page, or email hire@eventproductiongroup.co.uk. Our Christmas light trail hire post covers the equipment side, and our lighting and creative services pages cover the design and the crew who build it.
