Figures show house prices for Q3 are also up 6% on the same quarter in 2014.
Up to 296 properties were sold in Jersey in the latest quarter and the average house price on the island is now £453,000.
Dan Edmunds, Statistical Officer at the States of Jersey, said: “Figures have exceeded the previous peak levels for the first time in seven years, both on a rolling quarterly basis and a quarterly basis. This is the first time house prices in Jersey have clawed their way above the 2008 levels.”
All property groups saw a price rise this quarter except for one-bedroom flats which now have a mean price of £212,000, £4,000 down from Q2 this year, but £2,000 more than in 2014. The mean price of two-bedroom flats is now £347,000, £46,000 higher than the previous quarter, and £7,000 than the annual average last year
Mr Edmunds said: “The gap between one-bedroom flats and everything else has increased this quarter. Two-bedroom flats have been slowly creeping up in value, although because of the small number of properties, sales of the occasional penthouse flat for above £1 million can push up mean prices.
“There has been a steady trend upwards for three-bedroom properties and they are up on the previous quarter. Four bedroom properties cover a really big selection of different housing types, from mansions to properties under £400,000. There has been a bit of a jump but we’d need a few more quarters of data to see what might happen.”
