Delivery drivers work with professionals and businesses across all sectors of the UK industry, including professional services firms and offices. The professional services industry includes accountancy, law services, auditing, tax, and advisory work, but the term can also be applied more generally to professionals working in offices. Professional courier services are a key sector in the UK’s economy, with companies like Deloitte and EY underpinning much of the financial work which keeps the country’s biggest businesses alive.
