One in three electric blankets tested in Brighton and Hove were found to be unsafe.
The fire brigade is also offering to fit smoke alarms for free.
Last year the council and fire brigade tested 155 electric blankets and found that 34 per cent – more than 50 – were unsafe.
This year’s free tests will take place at a number of venues across Brighton and Hove next week – from Tuesday 21 to Thursday 23 September.
To find out where and to make an appointment, call the council’s fair trading office on 01273 292494 or email Donna Lynsdale on firstname.lastname@example.org.
Councillor Dee Simson, the council’s cabinet member for community safety, said: “It’s great to see a free service like this being offered to residents of the city and we really hope people take full advantage by getting their electric blankets tested.
“Those who use electric blankets may be putting their lives in danger and given the statistics from last year it is clear to see that some of the blankets do not meet the correct safety standards.”
The fire brigade recommends that all electric blankets are tested every three years and replaced every ten years.
When buying a new blanket people are also advised to look out for the British and European standard and safety certification mark.
The council is urging everyone to check for wear and tear, dampness, scorch marks and flex damage before using their blankets this year.
