The four programmes, presented by Quentin Willson and produced by Mentorn, follow the success of 'Britain's Worst Driver', 'Britain's Worst Cook' and 'Britain's Worst Pet', which ran earlier this year.
Alex Sutherland, Five controller, said: "The Britain's Worst brand, which began with 'Britain's Worst Driver', has proved a huge success and the format has developed its own distinct character. The programmes are cheeky and fun and a celebration of the triumph of hope over hopelessness."
He added: "The specials we did earlier this year were great hits, especially with younger viewers, and I'm looking forward to these new ones being just as successful."
'Britain's Worst Husband' was the most popular peak-time commissioned programme among 16- to 34-year-olds so far on Five this year, averaging a 16% share of the demographic's viewing.
Five is also doing well out of the strand internationally, with 'Worst Driver' having aired or in production in 13 countries, with the latest additions being NBC in the US, VTM in Belgium, TSR in Switzerland and TVNZ in New Zealand.
