Oxford is the top place to invest in property outside London, according to TV experts.

Kirstie Allsopp and Phil Spencer, pictured, described the city as "investor heaven", because of its winning combination of large numbers of students, young professionals and families.

And they predict average house prices could soar by a staggering 42 per cent in the next four years, from £265,034 to £377,673.

The findings were revealed on the Channel 4 programme Where Best to Invest, with Oxford topping the pile for investors outside London, beating Cambridge into second place.

The report highlighted North Oxford and Jericho as being particularly good for investors, thanks to growing demand from young families and professional couples.

The programme, shown on Channel 4 on Tuesday, has already provoked a response among property agents.

John Scrafton, manager of the Cowley branch of Andrews estate agents, which had a property featured in the show, said he had been taking inquiries yesterday from London-based individuals interested in investing in the city.

He said: "The programme has already created a wave of interest, because property is cheaper here than in London. The university is a key factor, as is the hospital for Headington, where you can pay up to £900 a month for a one-bedroom flat."

And Suzanne Webb, lettings manager at Oxford-based Cluttons estate agents, said the quality of Oxford's schools was drawing people from abroad.
