Entirely depends on the nature of your visit.
Barbados is not included on the UK Border Agency list for Visa and Transit Nationals and as such you can visit the UK without a visa. If however, you intend to work, study, marry or essentially perform any activity other than short-term tourism then you are likely to require a Visa.
You shouldn't make travel arrangements though without checking first with the relevant authority as visa restrictions and arrangements can change suddenly. The UK Border Agency has a website that will keep you up to date on all Visa requirements.

UK citizens can travel to Barbados without a visa for up to six months.
