Owners of old, broken and bent ladders will be able to trade them in for a new one at a discounted price at participating outlets.
First introduced in 2007, the annual initiative is now run by the Ladder Association, which took over the programme from the Health & Safety Executive last year.
In 2012 it ran for three months and saw a 35% increase in the number of ladders exchanged. This year it will run for an extra month to target domestic ladder users putting up lights for Christmas.
Ladder Association chairman Cameron Clow said: “It will enable us to remind the public of the need to check and inspect ladders and stepladders before using them to put up Christmas lights and decorations, and, of course, how to use them safely.”
A full list of where old ladders can be exchanged is on the Ladder Exchange website, www.ladderexchange.org.uk.
