If you own a business, you probably think it's the best in the industry, but might not be so eager to test it. In this programme, four pairs of bed and breakfast owners from all over Britain put their money and reputations on the line by staying at each other's establishments. They pay only what they deem to be an acceptable amount for the experience, with one establishment being named as the best value for money.
The competition begins at luxury weight-loss and detox retreat Slimmeria in East Sussex, owned by Galia and Michael. But what will their guests make of the 9pm curfew?
Jan and William host at their five-star gold-rated B&B, 38 St Giles in Norwich, where their guests have the ride of their lives on the race track and are blown away by breakfast.
Fun-loving Ann and Bill host at their four-star B&B in Bude, north Cornwall, with Cornish cream tea, a local stick dance, a drink in their garden shed, and 'weekday caviar'.
Diane and Max are the last to host, at Ombersley Bed & Breakfast in Worcestershire, where there's bickering over gluten-free bread and hand washing, and some underwhelming eggs.
It's the final day and the B&Bers meet for one last time to find out how much they've been paid and to settle some scores, before the winner is announced.
Alan and Sylvie host at Watersedge Guest House in Barton on Sea. Mike and Danny waste no time in grumbling about the grime in their room. Can a spot of deer-watching win them over?
Tim and Amelia welcome their rivals to their non-star-rated boutique accommodation, Nearwater, on the south Cornish coast. But Sylvie and Alan aren't sure what 'boutique' means...
Austrian-born artist Eva hosts in her cosmopolitan B&B, Roundhouse Hotel, on Weymouth seafront. Mike and Danny are shocked by the exposed shower.
Showmen Mike and Danny host at the four-star Homecliffe Hotel in Blackpool. Sylvie and Alan have a great view... of the local car wash. And at breakfast, Eva sends her food back twice!
It's the final day and the B&Bers meet one last time to find out how much they've been paid. Only one establishment can take the title of best value for money B&B. Who will it be?
Steve and Beverly Green welcome their rivals to Centery Farm in north Devon. Their sheep-herding activity is hit by rain and fog, so the group herd ducks instead.
The second visit is to The Little Gloster on the Isle of Wight, where owner and professional chef Ben Cooke shows his guests how to make gravlax and the vodka-based shot akvavit.
Stephen hosts at his four-star Old Hall House, where the on-site activities include shooting and archery. And guest Sandie makes a surprising revelation to the group.
The final visit of the competition is to The House of Agnes in Canterbury, run by ex-hotel inspector Sandie. But could Sandie's former job backfire on her?
It's the final day and the B&Bers meet for one last time to find out how much they've been paid. Only one establishment can take the title of best value for money B&B. Who will it be?

Alan and Jane welcome their first-ever guests aboard their brand-new, purpose-built hotel boat, the Geanna, and pull out all the stops with a champagne cruise along the Thames.

It's the final day and the B&Bers meet for one last time to settle some scores and find out how much they've been paid. But some of the hosts' emotions run away with them.
