Season 4

Jo McDonagh runs Barton House in Blackpool with daughter George. While some of the guests are pleased at how well connected their room is, for others there's a bit of a sniffy issue to be resolved. Later there are high notes when Jo and George and their guests have a sing off, but bum notes at dinner when father and son duo Chic and Jason Henderson decide to put fellow guest Keri on the spot.

Opening the door this time is Well House Manor in Melksham, Wiltshire, where computer trainers Graham and Lisa Ellis mix IT with B&B: a combination that on arrival leaves Chic and Jason feeling more like delegates than guests. Graham takes the guests on a historical tour of Melksham, otherwise known as the 'town of milk'. At dinner some of the questions get too personal for some of the guests and results in a swift exit for some next morning.

It's the last day of the competition and the turn of best buddies Ben Turpitt and Keri Remes and their Apple Wood Glamping in Worcestershire.

Megan and Dick try to make the guests feel at home at their B&B in Cornwall. Things get off to a positive start, when the guests find the rooms spotless. Later on Megan drops a bombshell about her posh background, while Dick's eight inch Cumberland sausage causes quite a stir among the guests at breakfast.

James and Judith Calderbank welcome their guests to their very rural B&B in Devon. But the back-to-basics approach doesn't go down well with all the guests.

The final B&B of the week is Satis House in Suffolk, where Kevin Wainwright and partner David Little think Satis-faction's guaranteed. But is their breakfast bacon too crispy?

The B&Bers come together one last time to find out what they've been paid and confront their critics head on. Alfie and rival owner Megan get into a debate about Alfie's fast food breakfast and Megan wants to know why Alife thought it necessary to use a hairdryer to heat up his room. And David and Kevin get teary eyed as they realise they misjudged Alfie and Phil.

Partners James Reay and Simon Dooley run the one-star Winterbourne Hotel and Theatre Showbar in Blackpool. For well-heeled couple Dominic and Stephanie a trip to low-budget Blackpool is uncharted territory, but they take it in their stride and even go along with with the nightly cabaret show. Ian Lambert and Ali Imiolek are relieved to be able to let their hair down, and it seems there's a clean sweep of happy campers. But Andrea and Nick's feedback is enough to send James storming out of the room in a fit of rage.

The latest B&B is Northrise Lodge in Hastings, run by self-confessed perfectionist and cleaning fanatic Andrea Hickmott and her partner Nick Bonner-Williams. While some of the guests find their room too 'clinical' to relax in, Andrea has a meltdown after forgetting to put sugar on the table at breakfast.

B&B veteran Paul Workman is the no-nonsense owner of Hamlet House in Stratford-upon-Avon, where moany guests are given short shrift. Paul makes the most of the Shakespeare connection by taking his guests to perform some of the Bard's best bits. Paul serves potato smiles for breakfast but loses his cool when a hair is found in the mushrooms.

Second to host are B&B newbies Ben Gray and Katie Keegan in Cumbria. The guests are wowed by the rooms in the 16th-century manor house. But Veronica and Saida are ushered out to a yurt in the woods. The prospect of the midnight hop to the loos fills them with dread and they make their yurt feelings perfectly clear on check out.
