FAMILIES in Scotland are £10 a week better off than they were this time last year, the largest annual increase in the average household's spending power since 2009.

A new report has found that the domestic finances have been given a boost by drops in the the price of petrol and the cost of electricity and gas, while wages have also begun to rise.

According to the latest Asda Income Tracker for December, families north of the border had £180 per week to spend once taxes and bills had been paid for, up from £172 in 2013 and £170 the year before that.

The price of filling up their vehicles at the petrol pumps fell by a record 10.5 per cent at the end of 2014. The cost of petrol dropped to just 116.3p per litre and diesel to 122.2p per litre, while electricity and gas prices fell by 2.1 per cent year on year.

Also helping families to beat the January financial blues has been the a drop in the price of food and drink, which went down by l 1.7 per cent last month and essential item inflation fell to just 0.2 per cent.

At the same time, wages grew at 1.8 per cent as the economy continued to improve and leave the dark days of recession behind.

The number of people in work also remains stable, with the the government announcing that Scotland's unemployment rate stands at 5.7 per cent, just below the UK rate of 5.8 per cent.

The tracker found other indicators that household budgets were likely to stay in the black, with the cost of living in Scotland increasing by just 0.1 per cent over the past year, while average discretionary incomes grew by 6.0 per cent, equalling £10 in the average person's pocket each week.

With the exception of Wales, all regions in the UK saw an acceleration in income growth, driven by a combination of increasing employment and better pay.

Sam Alderson, Economist at the Centre for Economics and Business Research said: "Households are currently experiencing a considerable boost to their finances from the combined effects of rapidly falling, record low inflation, rising employment, and wage growth at its fastest since the financial crisis."
