The report, which is prepared in collaboration with the Confederation of Indian Industry (CII), monitors UK registered businesses with ultimate Indian parent companies and identifies the fastest growing corporates by turnover and employment size.
It finds there are currently over 700 Indian-owned small to large-sized businesses in the UK, collectively employing over 100,000 individuals.
Of these, 41 organisations were identified as registering year-on-year growth rates of more than 10 per cent, with more than half (26 corporates) demonstrating particularly strong growth in excess of 20 per cent.
These 'Top 41', the report suggests, generated combined revenues of around 19 billion pounds.
Despite outliers, such as Tata Motors (accounting for more than 80 per cent of the Top 41 group's total turnover), the group represents a broad range of large corporates (5), mid-sized corporates (17) and SMEs (19) across the UK.
Anuj Chande, Partner and Head of the South Asia Group at Grant Thornton UK LLP, commented: "The appetite and opportunities for successful UK investment by Indian companies remains as strong as ever. In light of sluggish growth potential in India, investors are increasingly eager to enter or scale up their UK operations as the British economy re-enters a growth phase."
The UK and India's cultural history also plays a large part in many Indian executives decision to set up a base here, giving them direct UK market access and a springboard into the recovering European market, he added.
"Ranjan Mathai, High Commissioner of India to the UK, launched the report earlier this week at an exclusive dinner attended by some of the fastest growing and largest Indian employers.
He said, "I am very pleased that this research has been conducted to show the strength of Indian investment and the range of business in which they have invested in the UK. This complements the UKTI statistics of India being the 5th largest investor in the UK last year.
"The pharmaceutical/chemical and technology/telecom sectors represent over half of the organisations in the Top 41 (22 per cent and 32 per cent, respectively); although the automotive, transport and engineering and manufacturing sectors are also strongly represented," Mathai added.
Geographically, the Top 41 had operations spread across the UK, with 29 per cent based in London, 32 per cent based in the South, 29 per cent in the North and 10 per cent based in the Midlands.
The report also identifies 12 Indian corporates, each employing more than 1,000 people in the UK.
