Backed by AI that handles the heavy lifting, our people focus on what matters: judgement, better questions and turning complexity into clear advice. Through our audit, tax and advisory services, and across more than 150 markets, we help clients go beyond the expected.

The audit practice remains a separate entity (Grant Thornton UK LLP) in which audit partners hold the majority of voting rights, protecting audit independence. The advisory and tax practice operates through Grant Thornton UK Advisory and Tax LLP, which includes Cinven as an investor alongside the partnership.
