In the UK the IBM PC was a very rare beast outside of a blue chip company, they were just too darned expensive.
In January 1984 the IBM PC XT was the only version on offer, using an 8088 or 8086, the PC AT had not even been announced. The tape only version with built in BASIC on ROM would probably set you back ~£1500, if you were lucky, with MGA mono-graphics maybe. Then you had to add the monitor for a couple of hundred more.
Most people and small companies just couldn't afford that sort of money. It was almost the price of a small car!
Even at £400, the Sinclair QL and BBC Model B were way out of the price range of the average person, being close to half a month's wages, if not more. This is the main reason that the ZX Spectrum sold so well.
