Capital punishment! London is hit by house price plunge - but how are property prices doing in YOUR area?

House prices in London have continued to plummet, new data has revealed. Property values in two-thirds of London's postcodes plunged in the last year while the rest of Britain recorded slow growth. The latest House Price Index (HPI) by estate agent Purplebricks showed that house values fell in 23 boroughs across London and only rose in ten over a 12-month period to August this year. It comes amid an apparent slow-down in the market, with the average cost of a home in the UK rising by just 0.9 per cent annually and a measly 0.3 per cent from July to August this year. The biggest loser in the report was the Royal Borough of Kensington and Chelsea – which saw house prices drop by an average of £192,084 in the past year. Homes in the City of Westminster and the City of London also saw their values fall by £148,015 and £124,071 respectively. The latest HPI report will make grim reading for Chancellor John Healey ahead of next week's Budget. Despite reportedly dropping plans to extend the so-called 'mansion tax' to thousands more homes, property prices on the higher end have already started to feel the hit. This three-bed semi-detached home in St Albans is on the market for £875,000 and comes with a swimming pool and hot tub. The average home in the leafy commuter town of St Albans in Hertfordshire is now £655,974 after an annual price bump worth £20,539.

Under the controversial plans, houses worth £2million or more will be subject to an additional annual tax bill of between £2,500 and £7,500 per year from April 2028.Experts say the demand for high-value homes, many of them in the capital, has fallen since the levy was first announced by former chancellor Rachel Reeves in last year's autumn Budget.Homes in Andy Burnham's north of England fared better than the South and the capital. The North East of England recorded the highest annual price growth of 3.2 per cent – worth £5,105 – pricing the average property at £165,640. The North West of England saw house prices grow 2.2 per cent – worth £4,810 – and meaning most homes are worth around £220,393 today. The Manchester borough of Trafford was the second best performing area in the UK, with prices rising by £23,682 to £393,897 – some £150,000 over the Greater Manchester average. Homeowners in Wales and Scotland saw some of the greatest house price growth over the last year, with rises of 3.1 per cent and 2.9 per cent respectively.

Despite the doom and gloom in the capital, the borough of Kingston upon Thames recorded the strongest price growth with £27,645 added to average homes, now worth £597,587.London's commuter belt also performed well, according to the report. Homes in the leafy commuter town of St Albans in Hertfordshire are now £655,974 after an annual price bump worth £20,539. The Surrey district of Epsom and Ewell is another growth spot, with prices rising £17,810 to an average of £566,163 over the year.
