A £200,000-a-year primary school headteacher has been revealed as the borough’s best paid civil servant, earning more than the Prime Minister and even her own boss.

Isabel Ramsey is the executive headteacher at Bandon Hill Primary School, in Sandy Lane, Wallington,

Figures published in Sutton Council’s core financial statements showed she trousered £190,898 in salary, fees and allowances with a further £14,178 in employer’s pension contribution, bringing the total to £205,076.

Bandon Hill Primary said the salary was a reflection of work she did with other schools outside Sutton,

Critics said headteachers should focus on a single school rather than be "run off their feet".

By comparison the borough's chief executive Niall Bolger received a basic salary of £163,635, with a pension top up of £28,473 bringing his total to £192.108.

The Sutton chief executive would be Isabel Ramsey’s boss because the council is the school’s local education authority.

Prime Minister David Cameron receives a basic salary of £142,500.

Sutton Council and the Department for Education said headteacher pay was the responsibility of the school’s governing body and that Bandon Hill Primary School had not come to either authority seeking budgetary assistance.

A spokesman for Sutton Council said: "The level of pay for school staff is decided by school’s governors and not the responsibility of the council.

"We are aware of the salary figure for the headteacher which is much higher than usual.

"We asked the governing body to explain the package and have been told it covers school salary plus remuneration for work done at schools in other local authorities."

Ms Ramsey’s salary is up on the previous year, when she was paid a total of £172,218.

Ric Adams, chairman of Bandon Hill Primary School’s governors, said: "The salary level of all staff in Bandon Hill, including the executive headteacher, is determined by the school’s governing body.

"The salary figure currently being attributed to the executive headteacher is not an accurate reflection of the actual salary paid by Bandon Hill Primary School.

"Bandon Hill is a designated national support school and the executive headteacher is a national leader of education.

"Therefore the remuneration level quoted includes both pension contributions as per requirements and also reflects the work which the executive headteacher and the school do in supporting a number of other schools in several local authorities across the country."

Nancy Bonney, assistant secretary for NUT Sutton, said: "Every teacher I have ever met works extremely hard and their best for the children.

"I don’t think a headteacher should work at more than one school. Even if you have the best deputy, it is not the same.

"She must be run off her feet even if she is very well organised.

"I don't know about headteachers being paid so much more than their staff and I don't think one head should be running more than one school."
