Nothing in Coventry sits in that range.
What escorts charge in Coventry
One listing covers Coventry. It publishes an hourly rate of £150.
One price is not a market. There is deliberately no Coventry median here, because with a single published rate that figure would just repeat the one advert while looking like a statistic. For a number with weight behind it, the UK-wide picture is drawn from 117 listings.
Incall and outcall in Coventry
Of the 1 listing in Coventry, 1 offers both. Incall means you travel to them; outcall means they travel to you, and an outcall price usually assumes you are providing somewhere to travel to.
Why Coventry has so few listings
Coventry sits in the West Midlands, and like most of the UK outside the capital its advertising volume is small. London alone carries 81 of the listings on this site. That concentration is worth knowing before you read too much into a local price: a thin market means less choice and less competition, not that the published prices are wrong.
