Halloween Decoration (Indoors and out)

Timing

The clocks go back on the last Sunday of October, which in 2026 means darkness arriving before five o'clock for the whole of Halloween week. That is the practical argument for building a display around light rather than objects: for the hours anyone will actually see it, shape and silhouette are all that register.

It also sets the schedule. Decorations go up in the last week of October and come down within a few days — anything still lashed to a fence in mid-November has stopped being seasonal and started being neglected. Carved pumpkins are the exception to any temptation to start early, since a cut pumpkin begins collapsing within three or four days in mild weather. Carving on the 29th or 30th is the difference between a crisp lantern and a sagging one.

Indoors

The window is the most valuable surface in the house, because it is the only part of an indoor display that anyone outside will see. Working backwards from the street — a row of lanterns on the sill, a silhouette taped to the glass, a lamp behind rather than in front — turns one arrangement into two displays.

Inside the room itself, the approach that reads as deliberate rather than cluttered is to pick two or three surfaces and leave the rest alone. A mantelpiece, a stair rail, a table. Candles and battery lights at varying heights do more work than any amount of plastic, and dimming the overhead light does more than both.

The natural materials of late autumn are free and sit better in a house than anything shop-bought: branches in a jug, dried leaves, conkers, gourds, bare twigs in a vase. For households with small children, the calculation changes somewhat — lower shelves, nothing breakable at knee height, and the understanding that anything genuinely frightening will be encountered at three in the morning on the way to the bathroom.

Pumpkins, and what happens to them

Britain buys around 39.9 million pumpkins for Halloween and throws away roughly 22.2 million of them, a loss put at about £32.6 million a year. The underlying reason is simple enough: only around 59 per cent of people realise a pumpkin is food at all.

Both the flesh and the seeds are perfectly good — soup, roasted wedges, curry, seeds toasted with salt. Scooping into a bowl rather than a bin takes no longer. The lantern can still be a lantern afterwards, and once it is finished, it belongs in a food waste or compost bin rather than landfill, where the methane from rotting pumpkin does real damage.

A few things extend a carved pumpkin's life: carving shallow rather than through the full wall where possible, rubbing the cut edges with a little oil or petroleum jelly, keeping it outside in the cold rather than in a warm hallway, and using a battery light instead of a candle, which cooks it from the inside.

The garden and patio

Late October in Britain is wet and often windy, which rules out a good deal of what looks appealing in a catalogue. Anything lightweight needs weighting or pegging, inflatables need to be deflated and brought in before a windy night, and paper or card decorations have a lifespan measured in hours.

The display that holds up is built on the approach to the house: the path, the gate, the doorway. Lanterns along a path, a lit doorway, a few pumpkins on the steps. It reads clearly from the pavement, which is the only vantage point that counts, and it does not depend on anyone walking around the garden in the rain.

Trees and shrubs are the free structure. Uplighting a bare tree does more than filling a lawn with props, and silhouettes cut from board and staked in a border read far better in darkness than detailed objects do.

Keep the path itself clear. Decorations that narrow a dark footpath, trail cables across it or obscure a step become a hazard precisely when a stream of excited children in restricted-vision masks is coming up it.

Electricity and fire

Outdoor lights must be made for outdoor use — not indoor lights with an extension lead run through a window. The marking to look for is an IP code or a water-drop symbol, with the last digit of the IP code indicating water protection; three or higher is the outdoor threshold. Anything plugged in outside should be on a socket protected by a 30mA RCD.

Extension leads and adaptors are best avoided where they can be, since they are the usual route to an overloaded socket. Lights should be checked for damaged cable and loose wires before going up, and switched off and unplugged overnight and whenever the house is empty. LEDs are the sensible choice on every count: they use something like 80 to 90 per cent less electricity, last far longer and have no glass to break.

Naked flames are the other risk, and they combine badly with the other half of Halloween. Costumes for children are classified as toys rather than clothing and are tested to a lower flammability standard than everyday clothes, so a candle in a pumpkin at ankle height, beside a doorway where children in long synthetic costumes are queueing, is a poor arrangement. Battery tea lights remove the problem entirely and flicker convincingly enough.

The decoration worth skipping

Stretchy artificial cobweb is the one item wildlife organisations consistently ask people not to use outdoors. The RSPB warns that birds and other animals become tangled in it, and once caught, escape is very difficult — the material clings to feathers and wings, and the result is exhaustion or injury. It traps insects too, removing food from birds at a point in the year when they need it.

The alternatives are more effective anyway. Real cobwebs, left alone and picked out with a torch, look better than the synthetic version. Twigs bound into broomsticks, dried leaves, gourds and lanterns all do the job, and afterwards the twig piles shelter insects and hedgehogs rather than snaring them.

Signalling

A lit pumpkin at the door is the established shorthand for a household taking part, and an unlit house the shorthand for one that is not. It is worth knowing that most police forces publish a printable "no trick or treat" poster for anyone who would rather not answer the door — useful for older or unwell neighbours, and worth mentioning to them rather than assuming they know it exists.

One last consideration for anyone going large. Strobe and flashing effects can trigger seizures in people with photosensitive epilepsy, and sound effects on a loop are a genuine imposition on the house next door. Both are worth switching off well before bedtime.

Afterwards

Decorations that survive to be used again are the cheapest ones. Boxed by category rather than crammed in a bag, lights coiled rather than knotted, and anything fabric dried properly before storage so it does not come out of the loft in September smelling of mildew. The pumpkins go in the food waste; almost everything else, stored sensibly, does another decade.
