Part-time firefighters with an eye for a business opportunity are running a sideline as chauffeurs for hen, stag and children's parties.
Firemen Richard Langley, Simon Bound and Perry Hill
Called the Blues n'Twos and dressed in replica outfits, the off-duty Treorchy retained firefighters will pick up passengers in a specially-modified fire tender and transport them to parties.
Mr Bound, a firefighter of 19 years, said the 10 firemen all put in £200 to fund their new enterprise.
Leading fireman Simon Bound said: "We have been amazed by the phone calls.
"We just thought it would be local but we have had calls from Abertillery, Ebbw Vale and the other side of Bridgend."
"We have got one fire engine at the moment and we are looking to buy another one next week," he explained.
"We are going to put a fridge in the one we have got so we can have a bottle of bubbly in the back.
Stickers adorn the fire engine
"I heard of someone doing it in Newcastle and I mentioned it just before Christmas then I went looking for a fire engine."
Firefighter Perry Hill said he had heard of another business running a fire engine in Scotland but believes theirs is the only one in the UK actually run by off-duty firefighters.
Mr Bound said he has received calls about whether the firemen are genuine.
Richard Langley said: "We have been asked whether there are any good-looking ones here, I said we will have to recruit."
Mr Bound said he did not think the business would interfere with firefighting because the part-time crew have separate jobs anyway.
But he said if the Blues n'Twos crew saw an incident, they would stop and help.
He said fire chiefs have not been told about the business but Mr Bound says there should be no problem.
"As long as it doesn't interfere with the fire service I can't see any problem," he said.
"As long as there is a crew manning the station and the engines go out of the door."
Claire Morgans, for South Wales Fire Service, said: "We are only too happy that our firefighers are enterprising when they are not doing their part-time firefighting.
"As long as they are not trivialising the fire service and the public around Treorchy are not confused with the fire service and what is, basically, a bit of fun we haven't got a problem with it."
