When upmarket estate agent Savills had to call in a posh firm of plumbers to sort out a blockage in the Ladies, two unexpected things happened.

First, Pimlico Plumbers (run by millionaire Charlie Mullins – honestly, you couldn’t make this up), discovered that the cause of the blockage was condoms.

And next, an email from a director asking staff to refrain from “such activity” in the office went embarrassingly viral.

The email bearing the title “loos” was sent by Richard Gutteridge to some 50 staff at the Savills branch in Sloane Street, London.

It said: “After seven hours Pimlico Plumbers established the cause of the problem.

“Unfortunately the blockage was caused by a build-up of used condoms. Obviously such activity should not be taking place in the office.

“As well as being extremely inconvenient to have both loos out of order for an entire day, this has now cost the office a considerable amount of money.

“Please can we be considerate to the ancient Sloane Street plumbing going forward.”

The viral world was obviously delighted, although possibly rather surprised that it was Savills and not Foxtons.

But did the email mean that staff should not indulge in certain activity in the office? Not use condoms? Or simply not throw condoms down the toilet?

And who might those hot-blooded Savills people be?

Step forward the astonishingly resourceful Jamie Jago, living proof of how some PR people are worth every penny. She almost managed to shift the blame away from Savills and on to neighbours.

“Plumbers were called in to investigate problems with the ladies’ lavatories in Savills’ Sloane Street office,” she said. “It was discovered that the main drainage system, which is shared with adjacent buildings, was blocked with debris including condoms.

“The blockage has been removed and the system is now working.”

Gosh. And it isn’t even the silly season yet.
