Becky Wall BEM and her husband Charles have run A Plush Flush from their home near Hereford for 20 years.
They took over the Loo of the Year Awards a few years ago, and since then more than 5,000 venues have entered to be judged on the standard of their washrooms.
In the last year, two of the King’s estates entered the competition, with the Sandringham Estate in Norfolk and the Windsor Park Estate being judged against more than 100 criteria.
Becky said: “We are thrilled that premises from the Crown Estate have recognised our awards and have chosen to be part of what we do.
“We aim to educate the public around what ‘excellence’ looks like when it comes to away-from-home washrooms.”
She added: “I was flabbergasted and thrilled when our inspectors told us that at the Sandringham Estate Visitors Centre the King himself had a say in the design of the facilities and he also advised his team to enter our awards.”
The Loo of the Year Awards 2024 were held near Solihull in January, celebrating the industry that supports away-from-home washrooms and the people who work within that sector.
Charles Wall said: “When a venue is nominated either by a member of staff or a member of the public, they invest in an inspection which takes place in the summer and our inspectors are rigorous in grading the quality of those facilities.
“The best of the best are celebrated at our annual gala and we also award 18 trophies on the day to showcase the most outstanding standards and service.”
The top trophy for 2024 was awarded to The Centre Livingston, a shopping centre in Scotland.
The 2025 awards are now open for nominations.
