Can You Leave Garden Lights On All Night?
You can, but most people should not. The usual pattern is dusk until around 11pm on a timer, with perhaps a single low safety light later. That keeps running costs trivial, avoids annoying neighbours, and gives the garden's wildlife a genuine dark period.
What it actually costs
| Schedule | Hours per night (avg) | Approx. cost per month |
|---|---|---|
| Dusk to 10pm | ~3 | £1.50–£2.00 |
| Dusk to 11pm | ~4 | £2.00–£2.75 |
| Dusk to midnight | ~5 | £2.50–£3.50 |
| Dusk to dawn | ~10 | £5.50–£7.50 |
The four arguments for switching off
- Wildlife. Moths, bats and hedgehogs all rely on genuine darkness. An 11pm switch-off restores most of the night.
- Neighbours. Almost every light nuisance complaint involves lighting left on late. Timing it off removes the issue before it starts.
- Effect. Lighting is special partly because it is occasional. A garden lit every night until dawn stops being noticed.
- Fitting life. Fewer operating hours means longer service life, particularly for any fitting with a driver in an exposed position.
When leaving something on makes sense
A single low-output fitting at a side gate, on a set of steps, or by a back door is worth leaving on. It costs pennies, it means nobody arriving home late is fumbling in the dark, and it gives a modest security benefit. That is quite different from running a full feature scheme until sunrise.
Use an astronomical timer
An astronomical timer tracks sunset for Hastings across the year, so the scheme comes on at the right moment in June and December without ever being adjusted. Set an off-time and forget about it — it is the least glamorous and most useful part of a scheme.
