Ministers commissioned expert analysis of the policy, which found that it would cost £6.7m per life saved over the next decade. This, the consultants concluded, was not cost effective. Environment Minister John Griffiths said there was a need to accept that there was a cost involved. Regulations will be introduced in September next year for all new and converted residential properties in Wales to be fitted with sprinkler systems. Work is due to begin on the development of the regulations and the technical requirements necessary to introduce the Welsh law which will be subject to public consultation. Wales was one of the first countries to rule that all new homes are fitted with sprinklers but had set no timetable for its implementation. Ministers say it will save a predicted 36 lives and prevent an estimated 800 injuries between 2013 and 2022. The regulations is the result of the Domestic Fire Safety measure proposed by Ann Jones, Labour AM for the Vale of Clwyd, which was passed in the last assembly. According to UK fire statistics, there are an average of 2,168 fires, 17 deaths and 503 injuries in fires in residential premises in Wales every year. Mr Griffiths said: "We must seek to prevent avoidable death and injury from house fires and need to accept that there is a cost to introducing sprinklers into new properties. "These proposals are significant and important in taking forward fire safety. "Wales will be at the forefront of reducing fire risk and cutting the number of avoidable deaths and injuries caused by fires in residential premises." However, the government-commissioned cost benefit analysis from experts BRE Global found that between 2013 and 2022 the cost per life saved of the sprinklers policy would be £6.7m. They concluded: "Fitting sprinklers in all new residential buildings in Wales would not be cost effective."
The Welsh government is to press ahead with its policy of fire sprinkers in all new homes from 2013, despite being told that it is not cost effective.

Hafren Power wants to build an 11-mile barrage between Lavernock Point near Penarth, Vale of Glamorgan, and Brean near Weston-super-Mare, Somerset. But one of the barrage's key supporters Neath MP Peter Hain says the UK government has refused to commit to it. In June MPs said Hafren had failed to make the case that it would be good for the economy or the environment. In a report, the House of Commons' Energy and Climate Change Committee criticised a "lack of information and a perceived lack of transparency" about the proposal. The case for the barrage is "unproven" and Hafren Power "has yet to provide robust and independently verified evidence of the economic, environmental and technological viability of the project", the report said. MPs were warned also about the potential of job losses in nearby ports, and concluded the scheme is no "knight in shining armour" to meet renewable energy targets. The committee said the UK government should remain open to considering a project in the Severn but "far more detail and evidence" would be required to make an informed decision about Hafren Power's proposal. Supporters of the scheme argue the tidal barrage could generate 5% of the UK's electricity. And earlier this year, former Welsh Secretary Mr Hain said the time had come to press ahead and build the Severn Barrage as the proposal has been "studied to death". But speaking to BBC Radio Wales, Mr Hain said: "It (the UK government) refuses to say whether it backs it or opposes it. "In practice it has put it into the long grass and therefore as far as this Parliament is concerned it is dead in the water but not as far as the future is concerned." Mr Hain, who quit the shadow cabinet to back the barrage, said the government was guilty of "stubborn refusal" to engage. "It really made me feel that they weren't interested in it," he added. "It's very, very disappointing because it could have been and still could be under a future government in a future Parliament an absolutely key part of producing our energy security." When the scheme was launched, Mr Hain said the barrage would bring "considerable benefits" to the UK - creating about 20,000 jobs and generating 30,000 more in the supply chain and other parts of industry, giving an economic boost to south Wales and south-west England. The electricity generated would be equivalent to three or four nuclear power stations and thousands of wind turbines, he said. The UK government has been asked to comment.
Plans for a £25bn barrage in the Severn Estuary are "dead in the water" in the current Parliament, it has been said.

Emily MaitlisPresenter, BBC Newsnight@maitlison Twitter In the lower chamber there are about 30-35 tight races right across the country. The key may be the liberal, affluent voters - if they vote for the economy they back Republicans. If they vote for their social values, they go Democrat. That's a big if which decides who controls one house of congress. The senate is easier for Trump's party to keep, as a lot of the tight races are in states that went for him. Interesting ones will be places like Missouri, Indiana - Democrat senators sitting in very red states. Many of them are campaigning more like independents - cautious not to mention their own party , so they don't scare off Conservative voters. The red meat state But all eyes are on Texas where a young skateboarding Democrat, Beto O'Rourke, has got a truly Republican state within his grasp. His opponent is Ted Cruz - who clashed with Trump in 2016. But the president has supported him this time around - campaigning there often. And Texas is a red meat, red heart state with open carry gun laws. It's almost unthinkable they could elect a democrat. But anything could happen there this race. In Arizona - state of the late John McCain - two women are vying for the senate. The Republican is a former fighter pilot and its neck and neck. In Nevada a Republican is trying to hold on in a state won by Hillary Clinton. And this part of the world is getting less white and more Latino - which often means more blue voters. Florida is always a nail biter. The fourth term Democrat fighting the former Republican governor. They've clashed sharply on gun violence in a state that saw the young rise up after a mass school shooting. There are nearly 500 races across the country. Will this be a referendum on Trump? The president would like to think so.

Popular wisdom suggests that Donald Trump expects to lose the House of Representatives, although Democrats don't believe anything is in the bag.
