A FLAGSHIP city boutique hotel is being sued for almost £90,000 by a contractor, the Daily Post can reveal.

The Beatles-themed Hard Day’s Night Hotel celebrated a “phenomenal” first year at the end of January.

But a company contracted to clean the £650-a-night venue claims it was not paid for two months’ work.

It remains unclear why the alleged debt has gone unpaid. The company confirmed the matter was in the hands of its solicitors.

London-based cleaning outfit WGC said it is owed more than £87,000 in unpaid invoices, plus another £3,106 in late payment charges and interest.

A High Court writ includes an invoice allegedly listing 28 separate outstanding charges.

Jonathan Davies, a director of the £17m hotel, said: "We have an ongoing legal dispute with the cleaning company and we are unable to comment."

Hotel manager Mike Dewey said: "I'm not in a position to talk about it but obviously I'm aware of it. It's in the hands of our solicitors."

A spokeswoman said cleaning the 110-room city centre hotel was now in the hands of an "in-house" team.

WGC claimed an agreement was drawn up between former-hotel manager Trevor Lynn and its managing director Martin Birch. It stated the cleaning company would be paid £7.70 for each hour of cleaning plus a monthly management fee of £3,900.

The claim also says a later arrangement was drawn up saying public areas of the hotel would be charged at the higher rate of £10.59 per hour.

A writ lodged at the High Court, just days after the Hard Day’s Night's first birthday, said: “Pursuant to these arrangements, the claimant invoiced and the defendant paid invoices between February and September 24, 2008. The defendant has failed to pay invoices from September 25 to November 30, 2008, totalling £87,472.82.”

WGC is also pursuing the hotel for late payment charges of £1,010 and interest of £2,096.04. It says it will add £23.96 interest each day the debt remains unpaid.

WGC’s Kent-based solicitor, Mark Oakley, said he had not been instructed by his client to comment on the case.

The North John Street venue opened amid much fanfare and media interest last February.

It boasts Beatles-inspired rooms – including John Lennon and Paul McCartney suites costing £650 per night.

Bill Heckle, the man behind Cavern City Tours, conceived the idea of the "world's first Beatles-themed hotel" more than a decade ago. He and Cavern Tours colleagues Dave Jones, Ray Johnston and George Guinness bought the grade II listed former Central Buildings in 1992.
