Council tax inspectors will visit DisneyWorld next month at taxpayers' expense as part of an international tour to learn about increasing bills for homeowners, reports the Telegraph this week.

The topic of next month's Disneyworld seminar will be the forthcoming council tax revaluation exercise in England, hosted by the British representation.  22 million homes will be assessed under this initiative and as a result homeowners could face higher bills if they have additional bedrooms, large gardens or even a nice view.

The assessment will seek to ascertain whether a property has been recently converted, adding to its value.  One of the main tools that many expect to be used towards this end is "spy in the sky" aerial photography about which inspectors will be briefed at the Florida conference.

Details of these trips and conferences have been unearthed by Caroline Spelman, the shadow local government secretary.  She said: "The denials by Labour spin doctors that spies in the sky will be used look less than credible, given tax inspectors are swotting up on how they are used abroad."

According to the Telegraph, the Valuation Office Agency has already started "rolling out" its controversial "computer assisted mass appraisal system" across England, slowly gathering data on every home.  So far almost two million properties have received "value significant codes", meaning it's likely they will be pushed into higher council tax bands with increased bills in the future.

Ministers have also made it clear that householders who shut the door on inspectors or refuse to cooperate with them in any way at all could be fined £500 and receive a criminal record.

Ms Spelman said: "Labour may claim to have postponed revaluation, but in reality it is well under way by stealth. These foreign jaunts at the taxpayers' expense expose that John Prescott has tax-raising plans in store."
