Indian companies are a large part of the UK economy: Grant Thornton's 2026 tracker counts 1,912 Indian-owned companies in Britain with combined turnover of £105.77 billion, and technology is the leading sector among the fastest growers. This list covers ten Indian firms that UK organisations use for IT outsourcing, with UK revenue, UK entity growth and contract figures checked as of November 2026.
How we chose these companies
We picked Indian-headquartered IT firms with a clear UK footprint: a UK subsidiary, disclosed UK or European revenue, a named UK contract or UK acquisitions. Each entry includes at least two figures from a company release, Grant Thornton's India meets Britain Tracker 2026, a results review or a public profile.
The growth figures for UK subsidiaries come from Grant Thornton's list of the fastest growing Indian companies in Britain and refer to those UK entities only. Apart from XDQ Labs, which publishes this list, the order is not a ranking.
- Indian headquarters with Indian delivery centres

How UK organisations should choose
Begin with the regulatory context of your sector. NHS, central government, financial services and telecom buyers each have their own security, data residency and framework rules, so ask for UK references under the same rules. Mastek and Infosys have recent NHS work, Tech Mahindra has deep telecom roots and Coforge is strong in insurance and travel.
Then check the delivery model: how many people sit onshore in the UK, how much work moves to India, and who owns key decisions. Agree service levels, overlap hours with UK time, data protection terms under UK GDPR, and exit and knowledge transfer terms before signing.
- Ask for UK references in your sector
- Confirm onshore and offshore team split
- Check UK GDPR and data residency terms
- Plan exit and knowledge transfer up front
Market context: the UK India corridor in 2026
Grant Thornton's 2026 tracker shows Indian companies in the UK employed 203,549 people and paid £378 million in corporation tax, up from 126,720 people and £277 million a year earlier. Technology, media and telecom led the list of fast growers for the 13th year in a row, with 33% of the companies.
The UK and India signed a free trade agreement in May 2025 alongside a double contribution convention. India's commerce ministry estimated the convention could save about 20% of salary costs for Indian staff posted to the UK, though analysts said it may not change deployment levels much. XDQ Labs works with UK teams that want smaller offshore builds such as SaaS products and AI agents.
