It may be a time of austerity in the UK but not so in the Dragons' Den... business is booming as the self-made multimillionaires return to the screen, ready to boost the economy by investing in the brightest and best of Britain's entrepreneurs. Whilst the rules of the series remain the same, you will notice one change... the arrival of new Dragon Hilary Devey, who joins the line-up of the five fearsome financiers. Having scrimped, saved and self-sacrificed in the haulage industry to make her own fortune, Hilary has her own views on the products and businesses brought before her, and she's more than happy to take on her rivals in order to get the best deal. 34-year-old Georgette Hewitt, from Kent, finds out exactly how nerve-wracking it can be to climb those famous stairs and pitch to the Dragons. It's a real battle to compose her nerves, but one she must win in order to tempt the multimillionaires to invest in her answer to a common birthday party headache familiar to all parents. Entrepreneurs often take advantage of the latest government schemes and incentives when building their business, which is exactly what Chris Hopkins from Yorkshire has done by capitalising on the solar power feed-in tariff. But when a Dragon knows your industry inside out it's not always what you want. Add into the mix the most unusual use you could ever think of for a plastic egg, a circus act that's sure to go with a bang, and a mind coaching massage service, and you've got a formidable showcase of the Great British spirit of invention and innovation. As ever Evan Davis is on hand to dissect the events, with further action and reaction available through the Red Button.

Dragons' Den continues with eight more intrepid entrepreneurs pitching Britain's brightest ideas to the multimillionaire investors. Will any of them manage to make the Dragons part with their cash? Tonight's episode sees Londoners Krissy Sims and Kerry O'Brien AKA DJ Trickles and Lady MC enter the Den with a state-of-the-art turntable extravaganza in the back of their 4x4. The Dragons are often happy to demo a product but it is the business and how it makes money that remains their ultimate concern. Husband and wife team Liz and Alan Colleran from Dewsbury may be pitching their comfy caravan product - but will their Den experience be quite so luxurious and comfortable? Elsewhere, an Englishman, a Norwegian and a Scot walk into the Den. Shades for canines are on offer, there's an inflatable car-based device like you have never seen before and a Kent-based entrepreneur thinks honesty is the best policy when pitching without a formal business plan - but with an offer to help everyone get the perfect looking body for just 20 pounds. With further interviews and reaction available via the Red Button at the end of the programme.

It's a Den full of family businesses. Tim and Meena Kalia and their business partner Tricia Tierney try to talk the Dragons into investing in their innovative litter trays for dogs. The Den is taken over by a pirate, a street urchin and a hippy as Peter and Michelle Hart, plus five of their seven children, pitch their fancy dress business; but is their dream of investment pure fantasy? Brothers Jim and Richard George from Malvern believe they're in a strong position with their fence preservation company which is already trading. The business-savvy siblings have a deal in mind - but will the offer they're holding out for materialize? Others looking for Dragon investment include an 'all you can drink' membership club, an exercise suit that claims to burn extra calories, and some giant knitting needles.

Some of the nations' budding businessmen and women have already entered the Den, but so far not all of their products and inventions have received a rave reception. This episode sees more intrepid entrepreneurs climb the stairs in the hope of realising their own investment dreams. Numbers are crunched and ideas are interrogated as the five fearsome Dragons weigh up which side of the coin their decision to invest will come down on. A former disc jockey has a strategy, dress to impress to catch the attention of an investor. The DJ may have worn a DJ, but is that all it takes to part a Dragon from their cash? A Londoner hopes to alleviate a common worry for holidaymakers by locking up their valuables, but with just 5 per cent of his company on offer, can he guarantee a valuable return? Monterrey-born Marcela Flores Newburn pitches her Mexican food range complete with a full mariachi band, another budding entrepreneur asks the multi-millionaires to think of their homes, not as houses but as a source of income, and a former hairdresser has a product that makes money from thin air, but does he have the business plan to match?

Dragons' Den is once more open for business, with the five multimillionaire investors ready and willing to invest in Britain's best commercial prospects. This time all the world's a stage and the Dragons merely players when two business partners from Lincolnshire pitch their pantomime company. But by turning the Den into a makeshift theatre, can they prove that show business and financial business really do mix? Elsewhere, one entrepreneur uses his pitch to tell the Dragons a story about growing up in South Africa, rather than concentrating on facts and figures, but how will that go down with the multimillionaires? Plus two joggers enter the Den to pitch their fast-paced delivery service; and a young mum offers a solution to everyone's outdoor toilet needs.

Profitability and bottom line are back on the agenda as more business proposals are pitched to five of the most successful commercial brains in Britain. Each of the entrepreneurs entering the Den are hoping to convince the multimillionaires that their business is worthy of financial backing, but as well as a good product it takes steel and determination to secure the Dragons' cash. There are mixed fortunes in the Den this time as fashion-conscious twins try to persuade the Dragons to buy into their clothing range, a Teesside-based entrepreneur has a run-in with the investors over his decision to separate out the assets in his company, and a former firefighter asks the Dragons to invest in a car that thinks it's a bike. One multimillionaire also gets their feet wet while trying out a beauty treatment administered by fish, but will a bit of Dragon pampering lead to a clean sweep of offers?

There are some true inventors in the Den this episode, including a returning entrepreneur with a new outdoor space saving device, a golfing duo with a new take on the traditional tee, and a designer who has flipped the conventional umbrella on its head. The Dragons come face to face with a fellow multimillionaire and the Den is filled with children's teepees. With a fair amount of game playing, gambling and bargaining taking place, will anyone manage to secure a deal?

A brewer’s high-strength hooch pole-axes a Dragon, a cruelty-free watch strap uses some surprising materials, and the makers of an eco-friendly deodorant make the Dragons jump out of their skin.

A Welsh grandmother has the Dragons in fits of laughter as she cooks up a storm and offers a percentage in her food loving website. Usual Den rules are blown out the window when a Tyneside couple pitch their innovative haircare brand for children, and the man who has built the world's biggest sand sofa tries his luck for investment. Elsewhere, Peter Jones tries out an interactive game in a urinal, Deborah Meaden tries lava bread for the first time and Hilary Devey reveals what a multimillionaire's horse eats for breakfast.

Eight more intrepid entrepreneurs brave the Den hoping to gain a major cash boost for their business idea. It's a tense place to pitch with so much at stake, and these Dragons are famously hard to impress. The hopefuls will need to hold their nerve if they wish to succeed in getting the investment they require to take their business to the next level. A horror story writer attempts to scare the Dragons into investing, but doesn't quite get the reaction he expects, in fact it's a reaction never before seen in the Den. There's a blast from the past as two Mancunian sisters who first walked up those infamous stairs back in 2005, are now asking for investment in their new gluten free oriental dipping sauce range, but will it be a case of better luck second time around? And with the kids all back at school, two friends hope now is the right time for investment in their innovative children's backpack designs - have they got what it takes to part five of Britain's most successful business men and women from their hard-earned cash? Also pitching to the multimillionaire investors is a Northern Irish inventor with his unique range of wearable luggage, and love is in the air when two Dragons tie the knot using a rather unusual vending machine.

The Dragons' competitive natures are put to the test when the Den is turned into a game show set, as a former chat show host seeks investment for her television quiz idea. Although she has experience in this area, will the Dragons think the price is right? A 22-year-old student from Bolton surprises the Dragons with his unbridled enthusiasm for the UK's car parking industry, and a father and son from Yorkshire cause consternation among the multimillionaire investors with their firm, no-nonsense negotiating style. Also pitching for investment in the Den are a samba band, flowering tea and a man washing his hair with the help of a fully working shower.

Two graduates aim to impress the Dragons with their update to a 200-year-old invention, a product they believe creates a whole new way of advertising on Britain's streets. Will the pair's futuristic demonstration be enough to secure the cash they desperately need, or will the investors spot a fatal flaw? A beauty lover from Birmingham pitches possibly the smallest product ever seen in the Den, and a Lancastrian father of three has some explaining to do when his business building wooden huts comes under close scrutiny from the five multimillionaires. Other ideas seeking investment in Den include a multi-directional paint brush, a solution to the troublesome problem of 'pillow slippage' and a taxi driver's security invention, which is put through the Theo Paphitis break test.

It is another busy week in the Den as eight more entrepreneurs pitch to the Dragons for a cash injection in their money-making ideas. Often, a visual aid helps get across what is being pitched, and this time there is a plethora of props to help the multimillionaires understand the commercial potential of the businesses on offer. A ballroom dancer turned inventor brings a bit of sparkle into the Den via a tango and a glitter ball; Theo Paphitis and Peter Jones crawl into a new concept for the camping industry; and a labrador called Margot helps to sell the idea of doggy ice cream. Also in the Den: a world kickboxing champion, two Welshmen with their celebrity-backed toffee vodka, and three friends from London who hope to capitalise on empty loft space.

Dragons' Den is where life-changing business deals are made. The five multimillionaire investors are looking for the next big money-making ventures, so any attempt by an entrepreneur to deflect a question or change the subject can lead to some choice words and a quick exit. This week in particular the Dragons seem to have got out of their million pound beds on the wrong side. Tempers flare when one entrepreneur offers just one per cent of his business, valuing it at 15 million pounds; hackles are raised by a toastmaster from Staffordshire looking for investment in his 'male intimate wipes'; and the Dragons live up to their name when deciding whether to invest in an online store for second-hand goods. But can any turn it round and secure the investment they need? Also facing the Dragons are a TV stuntman pitching his horror-themed paintball experience, a husband and wife with a new DIY product and a man from Birmingham who believes his darts invention is a world first.

Tonight sees the penultimate episode of the current series, with more intrepid businessmen and women hoping to receive a cash injection from the five multimillionaires. The Dragons have already proven that they are willing to invest in the right idea - will they spot the next big thing tonight? Entrepreneurs include: two Berkshire design graduates who think they've solved the multiple-pint juggle when carrying a round back from the bar, a former celebrity PA who has an awkward moment when her mobile phone rings during her pitch, and an ex-DJ from south Wales who hopes his role-play disco will best demonstrate his product for sore feet. Also pitched are a website for 'amazing' retirees, a gadget to reduce our food waste, and a car that's also a barbeque.

The Den doors are closing after another record-breaking series, and despite the recession the five multimillionaire investors have dug deep to pledge 1.75 million pounds to some of the UK's brightest businesses. In the final episode of the series, two friends hope the Dragons are in the party spirit as they tempt them with their frozen cocktails, a keen sailor demonstrates a nautical use for part of his car, and Peter Jones meets his namesake pitching a safety product for babies. Plus, a device to stop your tights falling down, an inflatable Christmas tree, and a beekeeper complete with a swarm of bees.

A couple of university friends pitch their home-brew cider kits hoping to leave the Den victorious, and a loose-leaf tea company serve up a refreshing treat. The lift encounters a technical malfunction, and a former Economics student hopes to butter up the Dragons with his new nutty preserve. Will anyone walk away with a deal?

In this episode, a former city accountant enters the den with an entourage of dancers as she tries to win over the Dragons with her Nigerian-inspired snacks, a businessman from Sheffield pitches a lid for a cement mixer and new Dragon Nick Jenkins impresses everyone when he showcases his portfolio of languages and accents. Will any of the entrepreneurs impress enough to secure a deal?

Pitches include a post-term storage business for public schools, flat pack furniture and an engineer's invention to help dog and horse owners.

Budding entrepreneurs pitch business ideas to multimillionaires. Two former army captains hope to get the Dragons to stand to attention with their bespoke gifting business. A young duo pitch their innovative ticket comparison site and a pair of multi-millionaire entrepreneurs are seeking cash from the multi-millionaire Dragons' for their new safety device. Will the Dragons have finally met their match or will they see the potential in a deal?

The Dragons question the expansion plans of an escape room business run by two brothers, and a former international tax lawyer offers a bite-sized portion of her at-home teeth whitening business.

A tech expert pitches a digital solution to help the bereaved manage the affairs of the deceased, and best friends from London face a roasting over their mood-enhancing coffee products.

The entrepreneurs bidding for the Dragons' investment include a cat-loving inventor who thinks he’s found a pain-free way to keep feline teeth clean.

Peter Jones, Deborah Meaden, Touker Suleyman, Jenny Campbell and Tej Lalvani assess the profit-making potential of more business ideas, including a keen fisherman with a plan to market his own range of bait, a pasta home delivery service, and a brother and sister with a scheme to make money out of rubbish. Evan Davis presents.

Entrepreneurs pitch activity-packed weekend breaks for adults, vegan handbags with an X-rated twist, a home delivery app for shoppers and a range of homemade soups and stews.
