Technology giant's price comparison service being watched as part of wider review.
Software giant Google is being watched by the Financial Conduct Authority (FCA), according to a report in The Telegraph.
The newspaper claimed that Google had come under the spotlight during the regulator's thematic review into price comparison sites.
The report noted that there were "fears the search giant is using anti-competitive behaviour against rivals in the sector".
Google bought Beatthatquote.com for £38m in March 2011 and the FCA first announced its thematic review into aggregators in November last year.
Speaking at the time of the launch of the review, FCA director of supervision, Clive Adamson, said: "We've all used a price comparison website so we know how simple they make buying motor, travel or home insurance. We don't want to lose that convenience, but we do need to ask the question, 'does cheapest equal best?'
"We want to get to a place where consumers that use these sites buy with the confidence knowing that they have all the relevant facts."
Both the FCA and Google declined to comment for The Telegraph's article.
