Four pairs of B&B owners from across Britain take it in turns as hosts to decide which of their establishments provides the best value for money.
Seasons & Episode
This week's competition kicks off at The Sportsman in Whitworth, Lancashire, where Steve and Georgia are hoping to win over their guests with bargain rooms and big breakfasts.
Joe hosts the third visit of the week, at the stately, Grade II listed Cley Hall Hotel in Lincolnshire. The B&Bers find themselves steeped in history, before letting out some anger as they try out blacksmithing but a noisy night drives Paul to distraction, and both the Sarahs get a little too hot under the collar.
This week's competition kicks off at Rosaire Guest House in Llandudno, where host Jo and her mum Pat are going for a home-from-home vibe.
Rachel and Liam host the second visit of the week at The Queens Hotel in Harlech. Professional impersonator Liam is hoping to impress with his impersonations but an issue in the bathroom gives Pat a sinking feeling.
Visit three is to The Mill at Glynhir in Llandybie, Carmarthenshire. Mat and Helen are hoping their renovated mill will fit the bill. At first, their guests struggle to find fault - until Pat discovers that standards in the bathroom may have slipped. Things get prickly during a visit to a botanical garden in the afternoon but it's at feedback time that the hosts have the biggest thorn in their sides.
The week's final visit is to Hideaway Escapes in Pembrokeshire, where sisters Lesley and Sarah are looking to inject a bit of colour into everyone's lives. The idea of getting back to nature bugs half of the B&Bers - and things get spicy when one set of guests refuse their room and take refuge in the car instead, leaving Lesley and Sarah all revved up come feedback time.
With facility failings, bathroom blues and even one set of B&Bers refusing to even try out one of their rivals' rooms all on the agenda, Payment Day is set to be a feisty occasion. It remains to be seen who will emerge victorious when the dust settles.
The week kicks off at The Earlsdale in Devon, where married couple Lewis and James hope their bold sense of style will prove a hit, although a dribbly shower rains on their chances.
The final visit of the week is to The Railway Ramblers' Rest in Devon, where hosts Nikki and Terry hope their unique take on self-catering will secure them the plaque. However, simmering tensions between two of their guests threaten to derail things - and a simple breakfast the next morning isn't to everyone's taste.
