William Hill in London


We couldn’t be closer to the action in our London office. A 2-minute walk from Tottenham Court Road station, round the corner from Soho and Oxford Street means you’ll never be short of anywhere to go for a lunchtime stroll or a post-work drink. There’s plenty of green space too with Regent’s Park and Hyde Park not far away at all. Working in our London office you’ll also benefit from a heavily discounted Zone 1 – 6 travel card so you’ll be whizzing around London in no time.
