Parents are willing to pay a bigger premium to live near one high-performing south Bucks grammar school than anywhere else in the country, new figures reveal.

Average property prices around Beaconsfield High School are more than £250,000 more expensive than rest of the county, Lloyds Bank has found, with parents having to fork out on average £629,021 for the exclusive postcode.

Marlow commands the third biggest premium in England, with a home close to Sir William Borlase's Grammar School setting families back £220,082 more than elsewhere in Bucks.

And those choosing to settle near Dr Challoner’s High School in Little Chalfont will have to prepare themselves for a price hike of more than £168,000.

All three schools celebrated excellent exam results in August, with 91 per cent of Beaconsfield High pupils achieving A* to B grades at GCSE.

Borlase saw more than 70 per cent given A*s or A, and Dr Challoner’s slightly better at 72 per cent with A* to A.

The new figures show those who bought homes near one of the Top 30 schools just before their child first entered secondary school in 2011 have seen an average house price rise of £76,000 – an increase of 26%.

This is a significantly faster rise than in England as a whole, where the average house price has grown over the same period by £42,145 or 18%.

Andrew Mason, Lloyds Bank mortgage products director, said: "Schools with the best exam performance are proving to be an increasingly strong draw for homemovers, as we’ve seen house prices rise sharply in locations close to such schools.

“The popularity of areas close to high performing schools may mean that homes remain unaffordable for buyers on average earnings.”
