Three mother-and-daughter teams compete. Claire and Brenda from the Carlee hotel in Blackpool take on Jan and Lisa from the five-star Graeanfryn Farm and Debbie and Emma from Goltho House and Gardens.
The visits this time take in a no frills B&B in Skipton, Yorkshire, a luxury residence in Warwickshire, and an old-fashioned B&B deep in the Dartmoor countryside.
Chrissy's no-frills approach at Mallard House in Devon is a far cry from Amanda's at Worrall's Grove in Worcestershire. Judith from Number 3 at Settle is suspicious of Amanda's sharp appearance.
B&Bs in Somerset and Berwick go head to head in a week featuring an attack of lavender fumes, some controversial anonymous comments and a lot of friction.
Lynn from Valentino's prides herself on her obsessively clean rooms; the 500-year-old Peldon Rose isn't up to her standards, but will Lynn live up to her own standards when her rivals come to stay?
The last competitor is Ben Atkinson, the free spirit behind Full Circle Yurts in the Lake District. Initial reactions to Ben's Mongolian yurts are mixed, and the overall winner is revealed.
The first two visits are to Norfolk House B&B in Newmarket, Suffolk, home to Brent Noble and his wife Lynne, and the Cromwell Arms Pub in Romsey, Hampshire, part-owned by Annalise Hughes.
This visit is to the Grade II listed Old House Hilton in Shropshire where owners Fifi and partner Tim offer an 'old school' hosting style. And the best value B&B is crowned.
