The founder of London-based burger brand Nanny Bill’s, which is celebrating its tenth birthday this year, on being inspired by how own gran and what makes a good leader.

Describe yourself in one word

Personable.

What is the most important thing you’ve learned in your career?

That people invest into people at all levels. Relationships, trust, and how you treat others matter just as much as strategy or skill. If you’re kind, respectful, and surround yourself with the right people, opportunities tend to follow. I’ve always believed in investing in people and putting trust in them and that trust has paid real dividends over the years. We’ve seen front-of-house cashiers grow into general managers, and kitchen porters develop into kitchen managers. That kind of growth doesn’t just come from training; it comes from believing in someone’s potential before they see it themselves.

Tell us your biggest strength

My charm. People sense authenticity and there’s a way to talk tactfully that brings the best out in people.

What has been your biggest mistake?

I’d say it’s having too much trust in people. I’ve made the mistake before of believing that everyone you meet in business will have your best interest at heart, from a supplier that takes your money and runs, a finance company that lures you with hidden costs or an employee that promises and never delivers. It took a while to learn to not always take people at face value and understand that sometimes it’s just business and nothing personal.

What makes a good leader?

I believe leadership is rooted in approachability and the ability to connect with people on a human level. I strive to motivate through positive affirmation and goodwill, creating an environment where individuals feel seen, valued, and empowered. Calmness is key - especially in decision-making and problem-solving - allowing me to navigate challenges with clarity and composure. Above all, I take pride in being able to inspire others by articulating a compelling vision and “selling the dream” with honesty and authenticity.

Who has had the biggest influence on your approach to business?

I have to say my grandma, aka the original Nanny Bill, who ran a café in North London. It was her approach to genuine hospitality that inspired me to get into the business and eventually set up the brand. She had a direct honesty which could cut, but also a caring nature that made people feel special and welcome. And she could talk to anyone – which is somewhat of an art.

But I also have to credit my wife, Sian. She’s got this incredible, motivating ‘get up and go’ attitude - I honestly don’t think I would’ve taken the leap to start Nanny Bill’s without her pushing me and backing me all the way. She’s been instrumental.

And finally, I was also influenced by watching Anthony Bourdain and how he merged a passion for food, work and fun. That blend really stuck with me.

How do you stay motivated?

I stay motivated through a passion to give my kids an upbringing I didn’t necessarily have. But I’m obsessed with the idea that I get to do what I want every day running the business and genuinely love my Industry and the people in it. Plus having a low-key burger obsession definitely helps!

How often do you check your email?

Probably too often! I’m ashamed to say I’m an avid refresher to ensure nothing is overlooked sometimes. Nothing goes unopened!

How do you relax?

By switching off completely. Whether that’s through meditation or watching reality TV (Married at First Sight is my guilty pleasure, not gonna lie). It’s generally by doing something solely for myself. And eating - if it’s not a burger, my go to is American Italian. Chicken Parmesan, meatballs, pizza. One of my favourite restaurants is Grasso in Soho.

What was your dream job growing up?

I always wanted to be a firefighter or stuntman as a kid and then told myself I could be a TV presenter in the MTV days! As I got older, I just wanted to run a business where I could work my own hours and answer to no one.

What’s the best advice you’ve been given?

Treat people how you wish to be treated. Oh, and surround yourself with radiators, not drains.

What would you call your autobiography?

‘Mind Your Own Business’ - How I helped myself to help others.

Tell me something you think about the restaurant sector that almost nobody agrees with you on

That anyone can do anything given an opportunity and the right guidance. Experience and qualifications are overrated.

Do you have any business regrets?

I can honestly say I have no regrets but if I had to say one thing it would be that I regret being so frivolous with cash as a young man but everything till now has built me as a person and a businessman and what is meant for me will happen for me if I want it enough. I’m just happy to be here and I’ve had a charmed life so far.
