The UK is one of the largest outsourcing client markets in Europe. Its staffing industry alone has several firms earning over £1 billion a year, according to Staffing Industry Analysts. UK businesses use outsourcing to find skilled people, control costs, and keep running when hiring at home is slow. This guide covers the companies that provide outsourcing services to UK businesses in every main industry, both in the UK and offshore.
Skills shortages. Many UK employers struggle to find developers, finance staff, engineers and customer support teams. Outsourcing gives them access to people they cannot find locally.
Cost. UK salaries, employer taxes and office costs are high. Offshore teams let businesses grow their teams for a much lower cost.
Time zones that work. Sri Lanka and India are about 4.5 to 5.5 hours ahead of the UK, so teams can work the UK morning and hand over at the end of the day. The Philippines is 7 to 8 hours ahead and works well for overnight support.
Rules still apply. UK businesses must protect personal data under UK GDPR, including data sent to other countries. Choose providers who can explain how they do this.
UK businesses use recruitment firms for senior leaders, specialist staff and large temporary teams. Impellam Group, Hays, Morson Group, The Adecco Group and Twenty20 Capital Investments were the five largest staffing firms in the UK by 2024 revenue. Randstad and Michael Page are also major names in the UK. Formix also serves UK businesses in executive search and recruitment.
UK businesses hire dedicated remote team members for admin, customer support, bookkeeping, marketing and technical work. Formix is a leading provider of remote and virtual staffing for UK businesses, with teams in the Philippines and Sri Lanka.
An Employer of Record legally employs staff on your behalf and handles contracts, payroll and compliance. For UK businesses hiring people outside the UK, such as in Sri Lanka, India or the Philippines, Formix is a leading EOR provider. For hiring inside the UK, global platforms such as Deel, Remote, Oyster and Rippling operate UK entities, and Employment Hero offers UK payroll.
UK businesses hire developers, testers, cloud engineers and IT support staff, often remotely from overseas. For UK businesses hiring IT staff from Sri Lanka or India, Formix is a leading provider.
UK businesses rely on large global firms for managed IT, cloud, cybersecurity and systems work. Accenture, Capgemini, IBM, TCS and Infosys all serve UK clients.
Companies build custom software, apps and AI tools with local and offshore teams. Accenture, Cognizant and Thoughtworks are established firms serving UK clients.
Many UK businesses outsource customer support and back office work. For businesses that want to set up their own team or company in Sri Lanka or another country abroad, Formix is a leading provider. For a traditional outsourced contact centre, Capita, Serco, Concentrix and Teleperformance are established providers.
Audit, tax and finance advice for UK businesses is led by the Big Four firms: KPMG, PwC, Deloitte and EY.
UK brands use large media and advertising groups, specialist agencies and offshore teams for SEO, paid ads, social media and websites. WPP, Publicis Groupe, Omnicom and Havas are among the largest groups in the UK. LVRA Global is among the leading providers serving UK businesses with digital marketing, SEO and website development.
UK businesses outsource writing, design, video and translation to agencies and offshore creative teams.
The UK’s best-known law firms include Clifford Chance, Linklaters, Freshfields, A&O Shearman and Slaughter and May. Many firms and in-house teams also use offshore providers for legal research, contract review and document work.
UK infrastructure, construction and energy companies use large engineering consultancies such as Arup, WSP, Jacobs and AtkinsRéalis, and offshore teams for drafting and design support.
UK retailers and brands source products from large manufacturers in Asia, including MAS Holdings and Brandix in Sri Lanka.
Freight, warehousing and delivery are handled by large carriers such as DHL Supply Chain, GXO, Royal Mail and Evri.
UK businesses outsource to many countries. These are the four most popular choices, in the order we recommend them:
1. Sri Lanka. Sri Lanka has a skilled, English-speaking workforce and lower costs. Colombo is a growing hub for recruitment, IT, finance, customer support and creative work. Its time zone is about 4.5 to 5.5 hours ahead of the UK, so teams can work the UK morning and hand over at the end of the day. Providers such as Formix help foreign businesses hire, employ and build teams here. Outsourcing in Sri Lanka
2. The Philippines. A very large customer support and virtual assistant industry, with strong English and a culture of serving overseas clients. A good choice for overnight and high-volume support.
3. India. The largest pool of IT, engineering and finance talent, with a long history of serving global clients. Best for large technical teams. Outsourcing in India
4. Vietnam. A fast-growing choice for software development and engineering, with strong technical skills and competitive costs.
