You may want to know about this advice issued by Kent Trading Standards:
STAYING SAFE AND LEGAL WITH FIREWORKS
Although fireworks can play a big part in celebrations
like Bonfire Night, Diwali and Chinese New Year, they
can pose serious dangers. Fireworks are explosives
and burn at high temperatures so they need careful handling
and storage. Kent Trading Standards advise people
not to buy fireworks from anywhere they are not sure
about - like a van or a temporary unlicensed market
stall. Only buy fireworks marked BS 7114 or with a CE
mark – this shows that the firework meets British
or European safety standards. There are other important
legal restrictions.
People under 18 years of age can’t buy fireworks
or have possession of fireworks in public places. Offenders
risk the Police giving an on-the-spot fine of £80.
Fireworks can't be let off after 11pm except:
until 12midnight on Bonfire Night (5 November);
until 1am on New Year’s Eve, Diwali (13 November
2012) and Chinese New Year (10 February 2013).
They
must not be let off in the street or any other public
place. Complaints about noise should be reported to
the Environmental Health Office of the District Council.
Fireworks can only be bought:
between 15 October and 10 November;
between 26 December and 31 December; and
three days before Diwali and Chinese New Year.
For the
rest of the year, fireworks can only be purchased from
certain specialist licensed shops.
