After smoking in public places was banned a year ago, pub landlords across the borough are experiencing a mixed response.
Some owners report that, despite being disgruntled at first, most punters have willingly accepted the new legislation.
John Trayler, owner of The Old Fox in High Road, Ickenham, said: "When we opened in November 2006, we were smoke-free for six months, so people were well aware of the rules last July and no one has tried to flout the ban in the past year."
And Jan Rockell, day manager at The Culvert, in Cowley Mill Road, Uxbridge, agreed and said: "At first, we did get one or two customers trying to have a sneaky cigarette in the toilets, but since then, we have had no problems at all. Our beer garden can hold up to 150 people, and the weather has been pleasant enough for people to happily smoke outside without complaining."
Officers for Hillingdon Council have inspected more than 2,500 businesses and vehicles since the legislation was introduced on July 1 last year.
Just 13 fixed penalty notices have been issued, five of which have been to individuals smoking in a smoke-free place, eight for not displaying correct signs in smoke-free vehicles, and one business owner has been prosecuted for not displaying appropriate signage.
But Mandy Rhys, owner of The Black Bull in Victoria Road, South Ruislip, complained that custom had dropped by around 30 per cent since last July.
"We do have a smoking area which can hold up to 50 people, but it is not used as much as it could be."
And Declan Kelly, licensee of The Adam & Eve in Uxbridge Road, Hayes, agreed, saying that although trade was still busy during the warmer months, cold and wet conditions had driven away 40 per cent of customers since the smoking ban was introduced.
"Punters are happy to smoke outside in the summer, but we were hit pretty hard last winter, and this year could be even worse."
