First Dates
10pm, Channel 4
Like Gogglebox, Come Dine With Me and other successful reality shows, First Dates has begun milking its popularity by expanding the brand, recently creating a hotel-based offshoot. But the original format (two strangers bristling with awkwardness in a utilitarian London restaurant) is still where the magic happens – as proven by this cracking series eight opener, featuring a desperately sweet young couple and an uncomfortable coincidence.

Obsessive Compulsive Cleaners
8pm, Channel 4
As plenty of docs have shown, there’s nothing remotely funny about OCD. This show, however, tries to bring a positive application to the compulsion to tidy – as obsessive cleaners bring some order to the homes of people who might benefit from their spare fastidiousness. Tonight, Brits Tina and Mark travel to assist Patrick in Texas – since his wife died, his ranch has gone to pot. Five days of their attentions should fix things. John Robinson
Peter Kay’s Car Share
9pm, BBC1
Kay’s wonderfully gentle, Fiat-set comedy continues its second run, with John and Kayleigh not on their way to the office but rather to their annual work do. Most of the episode is spent following their journey home from the party alongside foul-mouthed Elsie (Game of Thrones’s Conleth Hill). As usual, though, it’s the pair’s will-they, won’t-they relationship – this time soundtracked by Forever FM’s romantic nighttime offerings – that keep this comic vehicle on track. Hannah J Davies
Billy Connolly & Me: A Celebration
9pm, ITV
With the Big Yin set to hit 75 later this year, and a career taking in work as a welder, folk singer, actor and comic, an hour-long special barely seems adequate to cover Connolly’s life. Nonetheless, this interview promises to reveal the comedian’s thoughts on the art of swearing and the power of laughter, offer some brand new performance footage and feature famous fans including compatriots David Tennant and Andy Murray. Mark Gibbings-Jones
How to Live Longer: The Big Think
9pm, BBC4
If the title gets your heart racing, you’ll find much to stimulate in this elegant doc, which explores the ways science is seeking to address the biggest causes of death: cancer, heart disease and dementia. Nobel laureate Paul Nurse is our shepherd on this journey through medical advances and ethics, from designer babies and transplants that use “ghost hearts” from pigs to therapies that treat ageing itself. Sophie Harris
Vikings
10pm, History
Last time we saw the bald, bearded and piercingly blue-eyed Viking king Ragnar (Travis Fimmel), he was masterminding an audacious raid on Paris. As season four of the enjoyably bloodthirsty and historically loosey-goosey Norse saga kicks off, the soulful berserker-in-chief is having visions of the gates of Valhalla while recovering from his near-mortal wounds. If that sounds grim, things aren’t looking great for Ragnar’s wily shipbuilder pal Floki either. Graeme Virtue
Bates Motel
9pm, Universal
Hardly easing itself into things gently, season five of Bates Motel continues apace, with Freddie Highmore’s Norman Bates off to visit perjured Sheriff Romero in prison. Suffice to say, the meeting is a bit on the tense side, with Romero promising to come for Norman when he least expects it. But things aren’t all bad. Chick offers our Norm a taxidermy-based business proposition, but ends up discovering a little more about his new partner than he bargained for. Ben Arnold
Film choice
The Host (Andrew Niccol, 2013), 11.20pm, Film4
Not the pulsating Korean sea monster movie, rather an adaptation of Stephenie “Twilight” Meyer’s sci-fi novel of the same name. It’s set in a futureworld where much of humanity has been overtaken by alien parasites, their presence indicated only by their human hosts’ bright blue irises. Saoirse Ronan struggles gamely as teenager Melanie, locked in an intense battle of wills with her inner alien.
