Manual shutters
Push-up, crank and chain shutters need no power, cost less and keep working in a power cut. Small push-up shutters are balanced by springs in the barrel, crank shutters use a gearbox and a removable handle, and large doors use an endless chain.
The downsides are effort and time. Winding a large crank shutter every morning adds up, and push-up shutters rely on springs that gradually lose tension, so they become heavy and need re-tensioning.
Electric shutters
A tubular motor inside the barrel, or a gear motor on the side of large doors, raises and lowers the shutter from a switch, remote, key switch, timer or app. Electric shutters are easier to use every day, can be grouped and automated, and modern motors include obstacle detection and soft stops.
They need a power supply near the box. On homes that usually means a fused spur from an existing circuit or a new circuit, and the electrical work is done to BS 7671.
Solar shutters
A small panel and battery power the motor, so no wiring is needed inside. They suit windows and standard doors with reasonable daylight, holiday homes and rooms where you do not want chasing in finished walls. Very large or heavy curtains still need mains power.
Which is better value over time?
For a shutter opened once in a while, manual is the cheapest option overall. For a shop or unit where staff open and close it every day, electric usually pays back in time saved and less wear from rough handling. Most manual shutters in good condition can be converted to electric later.
Escape routes
Whichever you choose, a shutter over a window or door you may need in an emergency must open from inside without a key, with a manual override or battery backup on powered shutters. We plan that at survey.
