Housebuilders saw their shares lift on strong market data, as traders bet these firms might gain from the worst floods for a generation in the North.

Taylor Wimpey and Persimmon made ground as estimates from accountants KPMG suggest the total economic cost of the floods could hit £5.8 billion, leading to renewed building and repair work.

The wider FTSE 100 Index was 60 points higher at 6314.6, amid thin trading and little corporate or economic news following the Christmas break.

Germany's DAX was two per cent higher, while the Cac 40 in France was up by 1.8 per cent .

The pound was a cent lower against the US dollar at just under 1.48, after data showed US house prices lifted 5.5 per cent in the 12 months to the end of October, up from 5.4 per cent the month before. Sterling was slightly down against the euro at just under 1.36.

KPMG also said insurers faced potential claims of up to £1.5 billion, following warnings of more disruption in Cumbria and southern and central Scotland as Storm Frank threatens to bring more misery.

IHS Global Insight chief UK and European economist Howard Archer added that December flooding could impact growth in the economy by between 0.2 per cent and 0.25 per cent, due to businesses not being able to open, loss of agricultural output, and people not being able to get to the shops.

Insurers fell in early trading, but later edged higher. More Than owner RSA was up 2.6p, to 433.5p, and Aviva climbed 2p to 521p.

By contrast housebuilders lifted after a recent report by the Royal Institute of Chartered Surveyors said it expected house prices to increase by around six per cent in 2016.

Traders are also gambling these firms will benefit from the new building and repair work that will come in the clear-up after the flooding.

Berkeley was up almost three per cent, or 98p, to 3711p, Persimmon climbed 67p to 2040p, and Taylor Wimpey was 7p higher to 204.2p.

Supermarkets were lower ahead of retailers reporting Christmas sales over the next few weeks.

Sainsbury's was 1.5p down to 265p and Tesco fell 0.3p to 151.2p, as traders fear falling grocery prices will continue to hurt profits.

It was another poor session for miners and oil giants as the commodity price rout showed little sign of easing.

The cost of benchmark Brent Crude lifted by more than a dollar to 37.73 US dollars a barrel after recent falls, but still remains close to an 11-year low hit earlier this month.

BP was more than one per cent off, down 5.2p to 360.8p, although Royal Dutch Shell climbed 8p to 1579p.

Worries over China's economic slowdown continued to weigh heavy on mining stocks, with Anglo American leading the FTSE 100 falls - down more than six per cent, or 20.7p, to 307.4p.

The biggest risers in the FTSE 100 Index were Hikma Pharmaceuticals up 107p at 2358p, Taylor Wimpey up 7p at 204.2p, Persimmon up 67p at 2040p and Smith & Nephew up 36p at 1209p.
