By Royal Appointment...

All these London businesses have the Royal seal of approval

We were wondering, do the royals have a preferred fungal toe nail treatment? Septic tank emptier? Peep show?

Whatever they chose to endorse, that royal crest doesn't do your business any harm - it guarantees a certain standard of service and gives an assurance of top quality.

Whether they wander down Oxford Street handing out these accolades themselves or just leave it to the minions, we're unsure, but we've put together a list of some of our favourites... of the royal favourites.

Fortnum and Mason, Piccadilly
181 Piccadilly W1A 1ER
Chancery Lane 0.42 miles
Shopping Destinations

The Harrods of grocery stores, Fortnum & Mason was given both the Queen and Prince Charles' exclusive stamp in 1955. Fun fact: they claim to have invented the Scotch egg. Although the Queen is known to stick to a super healthy diet of grilled meats and no carbs at dinnertime (she has reached the age of 90, after all), this is her go-to store for the eggy treats.

73-77 Regent Street W1B 4EF
Piccadilly Circus 0.11 miles
Mixed Clothes
Opening Times

The royals love a spot of hunting and horseriding. Barbour is where they buy their coats, which are suitably quilted and waterproof for all their outdoor pursuits in the British drizzle.

Car Dealers
Opening Times

Naturally the Queen isn't going to be seen driven around in a Ford Fiesta. Instead she favours Rollers, Daimlers and Bentleys. The latter created a unique limousine for her to be ferried around on her Golden Jubilee in 2002. She endorsed their Berkeley Square dealership in 2014.

Rigby & Peller image

Sloane Square 0.11 miles
Lingerie & Hosiery
Opening Times

Does Her Majesty wear lacy basques? It's one of the many lingerie garments celeb-favourite Rigby & Peller sell, as well as suspender belts and babydoll dresses. She granted them the royal warrant in 1960, so perhaps she's foxier than we thought.

Turnbull & Asser image

71-72 Jermyn Street SW1Y 6PF
Green Park 0.15 miles
Shirt Makers
Opening Times

When Prince Charles was given the power to hand out royal warrants, the first company he chose was men's bespoke clothing retailer Turnbull & Asser. In their own words "we have been the choice of discerning gentlemen for handmade clothing and accessories for over a century". 'Nuff said.

John Lewis image
John Lewis
278-306 Oxford Street W1C 1DX
Oxford Circus 0.15 miles
Department Stores
Opening Times

We can exclusively reveal that the Queen gets Bucks Palace's curtains from John Lewis (possibly), as the store has had her Royal Madge's seal of approval since 2007. Britain's favourite department store is also one of the most egalitarian, as every single employee owns a share in the company and therefore get a percentage of its profits.

Prestat image
14 Princes Arcade SW1Y 6DS
Piccadilly Circus 0.18 miles
Opening Times

The Queen is just like everyone else really, at least in terms of tucking into a big old box of chocolates. As well as endorsing Cadbury's, she likes gourmet chocolatiers Prestat. Their specialties are truffles, which they experiment with by flavouring with sake, cardamom chai and blackforest gateau.
