The competition moves to Sandwich, where owners Stephanie and Dominic Parker pride themselves on giving guests a taste of the luxury lifestyle. But over some champagne-fuelled parlour games it's clear that while everyone loves the digs, two of the couples aren't digging each other.

Nick Tyrie and his best friend Layla Amini welcome the guests to their pub in St. John's Wood, London. Singer songwriter Layla reveals her Top of the Pops past and treats the guests to a performance. Unfortunately John and Sue Blakemore are left cold by their 'corporate and impersonal' room. And do mountains of toast equal a five star breakfast?

Today's hosts are soul mates Peter and Sharron Sorsky, who share the warmth of their Liverpool home with this week's guests. On arrival at Kirkby Park B&B, via the industrial estate, Annette is immediately on her guard after noting the CCTV camera on the outside of the house. Things don't get much better during the room inspection, as guests find dust, curly hair, unspecified dirt, stains and a hole in the wall. Peter and Sharron have got a surprise package in store for their guests to see a part of Liverpool they would never expect: its wildlife. A tour of Knowsley Safari Park, provides a chance for the guests to monkey about. All that fun means things get a little sweaty in the back of the Land Rover, so it's back to the B&B for a shower... which is easier said than done, as the Kirkby shower rota proves fallible. Still, at least Peter and Sharron have lined up one of their favourite restaurants for their guest's pleasure: an all-you-can-eat Chinese buffet.

The competition heads north to Blackpool, where fun-loving pranksters John and Neil have hatched a plan to pay back Alistair for being a self-confessed Blackpool-hater. The fun continues at activity time as Neil appears in drag and leads the group to Funny Girls drag cabaret bar. Mark confesses he has never had such a surreal time, and even Alistair gets into the groove. Back at the Vidella the boys cook dinner providing a special blow-up guest to keep Mark company in the absence of his wife. Come the morning and Mrs Tee has had another bad nights sleep and again criticises breakfast. Plus there's yet another prank from the hosts - this time with a plastic egg.

For the final visit the group checks into Mark Crib's boutique B&B in Bournemouth. With top prices of £170 the chic rooms come with all mod cons and super deluxe bathrooms. The afternoon's activity is a speedboat ride along the Jurassic coast. All the guests approve - even Mrs Tee is full of praise. And after some initial uncertainty Mrs Tee also declares the following morning's breakfast to be `excellent'.

Claire Hilton is first to host, at Robertsbrook Guesthouse in Swanage. Claire feels she has got more than a sporting chance in the competition. But Claire's first guests Lynn Self and Ziggy Broome are dubious about the cleanliness of their bedroom. Ziggy leaves no stone unturned in his search for dust, even dismantling the bed, before deciding he would rather sleep in the wardrobe. Claire's next guests have stayed in a fancy pad or two in their time - with their singing daughter Charlotte Church. Later the group don festive costumes for dinner. But talk of the serious business of star ratings creates a tension that continues at breakfast.

There are tears, outrage and arguments as the group meet one last time to find out exactly how much they have been paid by their fellow hoteliers, and to air their grievances face to face.

Quirky couple Lynn Self and Ziggy Broome hope to impress with their two-star B&B in Falmouth, Cornwall. But with two of the guests - Charlotte Church's parents James and Maria Church - already saying that they wouldn't stay anywhere below a four star, it could be an interesting day. From the offset the guests are very unimpressed by their surroundings - from peeling wallpaper to a dirty toilet brush. At dinner, when James and Maria reveal the truth about their famous daughter, Nicky reveals she used to be Mr Blobby's fan-mail writer After an interesting night's sleep, breakfast reduces some of the guests to fits of giggles.

It is the last stay of the competition and the turn of newlyweds Pip Easby and Nicky Lesser-Easby, who run Muddifords Court Country House in Devon. While the Churches find their historical four-poster bed a bit small, not all of the guests enjoy the trip to a local glass-blowing factory. Over dinner some of the participants say what they think of each other, and during the night James gets cold feet. But despite some disappointing bacon at breakfast, the feedback at check out time the next day leaves the hosts feeling pretty confident.

The hosts meet for one last time to find out what they've been paid and to thrash out their differences. There's soon trouble as Mrs Tee finds out that it's Alistair and Emma who scored her only one lowly point for cleanliness. The confrontation continues when the roles are reversed with a heated exchange resulting in a walk out.

Charlotte Church's parents, James and Maria, run Dexby Townhouse in Cardiff. The hosts lay on a day of white-water rafting in tight wetsuits, and some magic tricks courtesy of Maria's young nephew Elliot. But, next morning, some of the guests are kept waiting for their breakfast.

Jon and Julia Shorrock host the week's first round of the B&B competition from their four-star Derwent House in West Sussex. The guests are split by gender to sample the area, with the men firing machine guns at a shooting range and the women relaxing at a spa - but a carpeted bathroom and shower without hot water raise questions.

It's Andy and Julian Banner-Price's turn to host the competition at their swanky Plas Dinas Country House in Snowdonia, where they've allocated their guests their priciest rooms, costing between £190 and £250 per night. Peter and Sharron arrive in North Wales still reeling from receiving their own feedback forms, and immediately begin finding fault with seemingly every aspect of their room, particularly the antique furniture. A visit to the local slate museum provides a chance for the B&B owners to wash bedding the old fashioned way, and far from being a busman's holiday, it proves an unexpected hit. When it comes to the feedback forms Andy and Julian identify the chief complainers as the Sorskys.

First to host this time is Mrs Tee in the New Forest Mrs Tee's eccentric ways charm the guests on arrival. But not everyone's room is up to scratch. John and Neil's bathroom window needs fixing and Alistair and Emma Mundell find they are sharing their room with ladybirds, cobwebs and dust. Mrs Tee's group activity is a master class in mushrooms master class and her home-cooked dinner also consists of mushrooms. At check out time while most of the guests agree that Mrs Tee's rooms just aren't up to standard, Alistair and Emma are the toughest critics.

It's Alistair and Emma Mundell's turn to host in sleepy Lynton, North Devon at their four-star premises which only opened three months ago. The B&B newbies are desperate to impress with their recently renovated rooms. The accommodation proves a winner with Mark and Fee and John and Neil, but Mrs Tee is proving more difficult to please. Later a ride on the Victorian cliff railway from Lynton to Lynmouth proves hard for two of their guests who are afraid of heights. Over dinner John and Neil reveal their B&B is in Blackpool - a town which which Alistair confesses is his `worst nightmare'. In the morning Mrs Tee says she didn't sleep because of traffic noise and is so critical of the cooked breakfast the other guests are reduced to hysterics.

Mark and Kathy start the competition at their grandiose Godshill Park Farmhouse on the Isle of Wight. Will their award-winning breakfast do the business for their guests? Mark and Kathy's hosting skills immediately come into question as Kathy asks Kalpana and Joseph from The Address to remove their shoes because of the cream carpets. When the guests see their bedrooms, Ruth from Crake Trees Manor is perturbed to discover she's been given a four poster bed, while Teresa and Clive from the Butterfly Guest House are shocked to discover dust behind the bath taps. The day's activity is clay pigeon shooting. Welsh couple Teresa and Clive label the sport as posh, but that doesn't stop them wanting to win. Later Teresa breaks into song at the table. As they bed down for the night Joseph is concerned that there should be more hangers available.

First to host are husband-and-wife team Paul Billington and Flora Loizou from Silverwood Lodge in Cambridgeshire, the only couple in this contest. As the hosts show their three female guests to their rooms, Caroline, owner of The Dean B&B, has a frosty view of the fact that they don't live on site. The hosts try to impress their guests by taking them punting down the Cam, but Sue from Seashells Guesthouse almost manages to capsize the group. Over dinner, straight-talking Nancy from The Old Court Guesthouse suggests that not living on site compromises the hosts' attention to customer needs. Come morning, Caroline has been kept awake all night by the noisy road and Nancy's TV 'doesn't work'. When the hosts read the frank feedback they are left livid and accusations of foul play fly.

Julia Grant's level of cleanliness as host at The Queens Hotel in Benidorm doesn't impress the guests, but their stay ends on a high note after everyone participates in the nightly drag revue. However despite a successful ending, some of the guest feedback leaves Julia fuming.

The contest begins at The Grange in Oxfordshire, where Graham Neil and his wife Cherry offer a picture-framing course and a morning bagpipe wake-up call. The competing guests are from South Wales, Edinburgh and Abingdon.

The competition reaches its second day, and the group visits the village of Llandysul, South Wales, to enjoy the hospitality of Katie Clamp and husband Andy. Edinburgh guesthouse manager Tony Costa is not happy to find dog hairs on his bed, and Graham Neil is unimpressed after taking a dip in the hot tub. Things seem to get worse when efforts to prepare a hearty breakfast backfire, leading to chaos in the kitchen.

Tony and Dawn Ann Costa, owners of the five star Amar Agua in Edinburgh, pride themselves on their high standards. They decide to entertain their guests with a meal at a leading restaurant, and a visit to a subterranean museum, but Katie keeps complaining and Tony and Dawn Ann struggle to keep calm.

Terry and Peter Boswell welcome the group to their Abbey Guest House in Abingdon, Oxfordshire. They organise a day trip to the Thames, but Tony and Katie are still feuding, and the situation only gets worse at dinner as the evening ends in tears.

The four sets of owners discover what the other competitors thought of their businesses by opening the cash-filled envelopes, which they filled with what they believed their hosts should receive. They meet for one last time to learn who has won the best value B&B of the week.

The contest begins at the Manor House Farm in the Norfolk countryside. The guests get a taste of Libby Ellis's no-nonsense approach when she reveals she does not like having teachers to stay - a profession to which competitor Irene Willson from Sussex belongs.

Self-confessed zany couple Pete and Irene Wilson invite their competitors to Butlers Farm in Sussex, but Bridlington pair Paul Sharpe and Lou Sittler are disgruntled by the fact they will be sleeping in the hosts' bedroom. Tensions continues to rise in the morning when the guests are unimpressed by overheated breakfast plates.
