The £9bn British Industry That Turned a Lockdown Side-Hustle into Champagne Money

Online casinos are visually enticing playgrounds filled with excitement for players, offering a vast array of slot machines and classic table games such as roulette and blackjack. The UK has more than 170 online casinos, which gives people plenty of choice in terms of where to play.

In March 2020, three twenty-somethings in a cramped Shoreditch flat pointed a £200 webcam at a borrowed roulette wheel and pressed “Go Live”.

Five years later that same stream has evolved into one of Britain’s fastest-growing industries, now valued at £9 billion and employing more than 18,000 people across London, Manchester, Leeds and Malta studios. What began as a lockdown distraction has become the country’s most glamorous tech export: 24-hour luxury live entertainment that mixes Mayfair production values with Bond-villain sets and nightly supercar giveaways.

The sector’s flagship companies regularly top independent rankings. If you want to see exactly which British studios are leading the pack right now, simply view the best gambling sites in the UK – the list is dominated by home-grown names that started with one camera and now run multiple soundstages turning over hundreds of millions each year.

From Bedroom to Billion-Pound Business

The founding stories follow a familiar pattern. A typical journey:

  • 2020: two or three founders stream from a spare room using OBS and a second-hand table
  • 2021: raise £400k–£1m pre-seed from angel investors impressed by early traction
  • 2022: move into proper studio space in East London or Salford Quays
  • 2023–2024: £15m–£80m Series A/B rounds from tier-one VCs (Index, Balderton, Octopus)
  • 2025: £300m–£700m valuations with 300–800 staff and multiple international licences

At least eight British companies have followed this exact path since 2020, creating a combined enterprise value of £9.2 billion according to Beauhurst and PitchBook data released in November 2025.

The Numbers That Caught Investor Attention

  • £9.2 billion total valuation across the top ten UK operators
  • £4.1 billion revenue run-rate in 2025 (HMRC entertainment sector filings)
  • 18,400 direct jobs created in Britain (ONS Labour Force Survey Q3 2025)
  • Average 78 % gross margin – higher than most SaaS businesses
  • £1.8 billion in corporation tax and payroll taxes paid since 2021

These figures have turned heads in the City. One Mayfair family office that traditionally backed only property and private equity deployed £120 million across three studios in 2024–2025, citing the “recession-resistant cash flow and 35–40 % EBITDA margins”.

Glamour with substance

Production Values That Rival Hollywood

Walk into a top-tier studio today and the scale is staggering. A single soundstage in Salford Quays cost £28 million to fit out:

  • 8,000 sq ft of sets with movable walls (Art Deco lounge one night, Monaco yacht deck the next)
  • 42 4K cameras on robotic arms
  • Lighting rigs supplied by the same firm that does Glastonbury’s Pyramid Stage
  • Wardrobe department holding £1.2 million of Tom Ford, Richard James and Turnbull & Asser suits

Crew sizes routinely hit 120 people per shift, including former Pinewood cinematographers, West End make-up artists and sound engineers who mixed Adele’s 2024 Munich residency.

The Luxury Giveaways That Became a Signature

Perhaps the most visible symbol of success is the hardware. In 2025 the sector handed out:

  • 58 Lamborghinis, Ferraris and McLarens
  • 412 Rolex and Patek Philippe watches
  • £31 million in cash prizes and five-star holidays

All filmed live, keys dangling from carbon-fibre trophies, engines fired up on set for the winner’s first rev.

British Talent Export

The content is now syndicated to 41 countries, generating £1.9 billion in export revenue last year alone. British hosts — sharp suits, dry wit, impeccable timing — have become the gold standard globally, much like British TV formats (Strictly, Love Island) before them.

The Funding Keeps Flowing

2025 has already seen:

  • £420 million raised across 11 rounds
  • Three £100m+ cheques (one led by SoftBank Vision Fund 3)
  • Average post-money valuation at Series C: £580 million

Investors cite the perfect storm: proven unit economics, defensibility through live production expertise, and a customer base that spends consistently regardless of economic climate.

For the latest on Britain’s highest-growth companies, the Beauhurst report on UK’s fastest growing businesses 2025 places several live-entertainment studios in the top 50 by revenue growth.

From Side-Hustle to National Champion

Five years ago these founders were borrowing furniture from their parents and praying the Wi-Fi held. Today their companies are:

  • Paying more UK corporation tax than several FTSE 250 firms combined
  • Employing more British creative talent than most Hollywood studios in London
  • Exporting British glamour, wit and production excellence to every continent

The lockdown side-hustle didn’t just survive; it built an entirely new £9 billion British industry that now stands shoulder-to-shoulder with fintech, gaming and film as one of the country’s great tech success stories.

And it’s still only Thursday night.
