Also, a GBP179 "WA903 Mobile Air conditioner" at 8000 "BTU" - whatever

Habicool Mobile Air Conditioner rated at 10000 "BTU" - yet again whatever
that is in real money.

AFIAK 1000 BTU is equivalent to 293W.

[If B&Q's previous daftness is continued, the unit's power consumption will
be shown on the data plate in Watts and its dimensions also in SI units.
Consistency ain't B&Q's strong point - presumably in order the better to
bamboozle customers.]

From the BTU and wattage the efficiency ratio or COP can be
calculated; COP = (BTU * 0.293)/W
