This paper determines the representation type of the Iwahori–Hecke algebras of type B when q≠±1. In particular, we show that a single parameter non-semisimple Iwahori–Hecke algebra of type B has finite representation type if and only if q is a simple root of the Poincaré polynomial, confirming a conjecture of Uno's (J. Algebra 149 (1992) 287).
