The Restoration Man
8pm, Channel 4
Perhaps it’s because almost nothing in life is as depressing as attempting to improve one’s own home that the demand for programmes about other people doing it remains so buoyant. In this episode of this strand of real-estate voyeurism, George Clarke visits Harrogate to observe the progress of Carol and Majid Nadry, who are intent on refurbishing a five-storey water tower. The couple have been beset by the delays and budget blowouts traditional in such circumstances, but has it all been worth it? Andrew Mueller
Line of Duty
9pm, BBC2
This will be the strongest LoD yet if it can maintain its momentum. After last week’s frantic opener, the board is flipped again as AC-12 continues to investigate Sgt Danny Waldron (Daniel Mays, for whom a new Bafta category needs to be created). Despite the pace, there are signs that the show’s main flaw – overwhelming complexity at the expense of sufficient emotional hinterland – is being rectified. Pro tip, though: if you want to keep a grip on what’s happening, re-read a series two synopsis beforehand. Jack Seale
Bear Grylls: Mission Survive
9pm, ITV
Eight days into the South Africa-based endurance challenge and only a clutch of D-listers are still in the running for the title of hopeless Bear Grylls impersonator of the year. Already out of the contest are actor Chelsee Healey, ex-footballer turned manager Stuart Pearce and Bob the Builder svengali Neil Morrissey, who appeared to be having as much fun as a vegan at Nando’s. This week, the final four split into teams to work their way across an estuary, and Grylls sets a challenge that truly takes the piss. Hannah J Davies
Ireland’s Treasures Uncovered
9pm, BBC4
In the final instalment of this series, Professor Alice Roberts and Dr Gavin Hughes pore over some of Ireland’s greatest finds, including the Tara Brooch, a symbol of Irish resistance; the dazzling Broighter hoard; the Book of the Dun Cow, a history of pagan Ireland penned by medieval Christian monks; and, perhaps wildest of all, a 4,000-year-old golden necklace discarded in a rubbish bin in 2009 after thieves inadvertently took it from a family-run pharmacy (the family had no idea what they were sitting on, either).

Marvel’s Agent Carter
9pm, Fox
Lights, camera, apocalypse: the season two finale of Marvel’s 1940s-set secret-agent caper tasks English firecracker Peggy (Hayley Atwell), horndog mogul Howard Stark (Dominic Cooper) and butler Jarvis (James D’Arcy) with averting a dimension-ripping cataclysm in Los Angeles. They face a gangster’s moll infused with volatile “zero matter” – and while the climax plays out on one of Stark’s fake-looking Hollywood backlots, the emotional fallout seems very real. With any luck, plucky Peggy will return. GV
Stewart Lee’s Comedy Vehicle
10pm, BBC2
Eddie Izzard may run marathons, but Lee remains the king of endurance comedy, a standup with the wit and grit to rolling-pin a single observation into a half-hour routine. Tonight’s episode is nominally about dunderheaded reactions to the so-called migrant crisis but, like a glitch in the Matrix, Lee gets locked into a repetitive but endlessly rewarding riff about Rod Liddle and random foodstuffs. It trundles and builds to his most demanding, and impressively heroic, checkout of the series so far. Graeme Virtue
The Snooker Mavericks
10pm, ITV4
First in a new series featuring the characters whose antics helped popularise, or alternatively bring into disrepute, their various sports. Upcoming episodes explore motorsport, boxing and darts. Tonight, it’s snooker – and Alex Higgins, Jimmy White and Ronnie O’Sullivan. Higgins’s story is the saddest: a brilliant talent laid low by alcoholism. He is contrasted with the supposedly robotic Steve Davis, ironically a genuine maverick who has carved a post-baize career as a champion of prog and techno. David Stubbs

Public Enemies
(Michael Mann, 2009) 11pm, ITV4
Mann brings his heavy-duty modern gangster method to bear on an outlaw of a different age: Depression-era bank robber John Dillinger. It’s a superbly crafted crime drama, with Johnny Depp as the charismatic crook and Christian Bale as his nemesis, FBI man Melvin Purvis. Counterpointing their mano-a-mano aggression is Dillinger’s doomed romance with hat-check girl Billie Frechette (Marion Cotillard). Paul Howlett
