They are exclusive areas where the average house will cost you more than £1million . But this year the Golden Postcode Club has expanded with four extra districts added to its select list . East Sheen in south-west London and Chiswick in west London both managed to nudge their way in with hundreds of properties breaking the £1million barrier . Scroll down for video . Four extra districts have been added to the Golden Postcode Club this year . One of them is Cobham , in Surrey , where Hatchford Hall ( above ) is . They join Guildford and Cobham , in Surrey , which were both added to the select band for the first time this year . The club makes up just 0.8 per cent of the UK 's 2,760 postcodes . The highest average house price was in W8 in Kensington , London , where buyers were set back around £2.65m , The Sunday Times reported . The data was collected by property website Zoopla , which compared average house prices in districts across the UK . Nearly all of the postcodes are in London . Kensington Palace Gardens ( above ) has typically been the most expensive street in Britain with an average house price of £36million in 2013 . It also showed that the number of areas where houses were worth more than £500,000 increased by nearly 25 per cent . While most of the postcodes were in or near London some - including Solihull in Birmingham , Bryher in the Isles of Scilly and Watlington in Oxfordshire - were hundreds of miles away . Twelve extra postcodes were also added to the list where the houses cost more than £750,000 on average . UK house prices rose by an average of £16,000 - or 8.5 per cent - in 2014 , according to Halifax . Chiswick in west London is also one of the newcomers to the club . It is where the Thames Zachary House ( above ) went on sale for just over £6.25million in 2012 . Most of the golden postcodes include houses that have vast extra rooms , including this conservatory at the Thames Zachary House .

In a statement to parliament Eric Pickles , the Secretary of State for Communities and Local Government , said too many people had been unable to get on the housing ladder . He said : 'Too many have found themselves frozen out of the housing market and denied the opportunities their parents had to get started in their own homes . '
