Googleâ€™s UK revenues surged to $7.07 billion (Â£4.92 billion) last year, its latest financial results show.
The group took $1.92 billion in revenues in the UK during Q4, up 16 per cent on the previous year.
Its total advertising revenue for last year came to $67.39 billion.
The results come just days after widespread criticism of Googleâ€™s tax arrangements in the UK, following a deal with HM Revenue and Customs whereby the company paid Â£130 million over a decade.
The company made a profit of $4.9 billion in the fourth quarter of 2015, up from $4.7 billion in the same period in 2014.
Alphabet, the parent company of Google, has now overtaken Apple to become the worldâ€™s most valuable listed company, helped by strong advertising sales.
Googleâ€™s share price in after-hours trading sent its market valuation to around $568 billion, beating Appleâ€™s $535 billion, a figure bolstered by better-than-expected fourth quarter results.
Ruth Porat, the chief financial officer of Alphabet, said: â€œOur very strong revenue growth in Q4 reflects the vibrancy of our business, driven by mobile search as well as YouTube and programmatic advertising, all areas in which weâ€™ve been investing for many years.â€
