Great Interior Design Challenge (BBC2, 7pm)

THE much-anticipated series three is about to hit our screens and judge Sophie Robinson says: "I’m forever amazed at the inventiveness, audacious ambition and sheer raw talent that our amateur designers demonstrate during one of the most gruelling TV challenge series. Bake a cake? That’s for wimps. There can be no underestimation how hard these guys have to work and I take my hat off to each and every one of them."

She and fellow judge Daniel Hopwood take on four amateur designers tonight to transform bedrooms in a 1930s former leisure centre in South London. Textiles salesman Frankie goes Japanese; youth worker Jane tries 1920s Bloomsbury set; Holly aims for a retro retreat and Jane seeks shades of Scandinavia.

"In the ‘real world’ first of all you’d get to meet you client face to face and view the property you want to design in the flesh. See the proportions and how the light falls, how the person lives within the space. But this isn’t the real world, this is TV and the hint is in the title. Daniel's job and mine is far from easy, and the designers make sure of that. They throw their all into it and with only a week to prepare their designs, it’s a roller coaster ride from start to finish," says Robinson.

Her checklist for winning your way through to the next round includes:

1 Has the designer tackled the brief? This is a key part of the design process. One thing we’re certain of is this isn’t a showcase for a designer’s ego. "So if we hear a designer say something like, 'I love this I’ve got it in my own house' (which we hear a lot), it’s a thumbs down from us".

2 Some clients, quite frankly, want the moon on a stick. It’s the interior designers job to edit a design, make it coherent and prioritise what can be done within the budget and time frame.

3 How creative have they been? The designers on The Great Interior Design Challenge regularly surprise us. It might be an original way of using colour or pattern or some ingenuous product innovation. If they’re innovative they’re likely to get fast tracked to the next round!

4 We are always impressed if a designer has tackled the boring bits such as the storage, the layout the lighting plan.

5 We’re also looking out for the interior designer’s people skills. How do they cope under pressure, how well do they work as a team?

6 How well the designers communicate and present their designs is an essential element in the judging process.

7 Some might argue that in the "real world" an interior designer isn’t required to have practical craft or making skills, but within the parameters of the Great Interior Design challenge, being able to create bespoke items for your project, takes the design up a significant notch.

Benidorm (ITV, 9pm)

GEOFF stages an intervention when Pauline falls off the wagon, but not before she has drunkenly befriended young Jodie – who was left under the not-so-watchful eye of Eddie while Billy and Sheron went for breakfast. The Solana wristbands are replaced by a new ID card system, but the technicalities of the new process prove too complicated for Mateo and the staff.
