Kingston upon Hull is a compact city with a river through the middle and a council boundary drawn tight around it.
Hull City Council covers the city itself, but Hessle, Anlaby, Willerby, Kirk Ella and Cottingham all sit in the East Riding of Yorkshire, which is a separate council, as is Beverley further north.
Customers in those places rarely think of themselves as living in Hull, and they search with their own village names.
The River Hull splits east from west, so a firm based off Holderness Road plans differently from one near Hessle Road, and every crossing adds time at busy hours.
The A63, Clive Sullivan Way, is the main road in from the west, and the Humber Bridge, a toll crossing, leads over to Barton-upon-Humber and North Lincolnshire.
Homes run from Victorian terraces and the big villas of the Avenues to post-war estates such as Bransholme and East Riding suburban houses. Much of the city is low-lying, so damp, drainage and flood worries shape a lot of trade work.
Rightmove, Zoopla and OnTheMarket hold the searches from people browsing listings. Estate agents belong to a redress scheme, heating engineers carry Gas Safe registration and electricians work through a scheme such as NICEIC or NAPIT.
