Where to Watch the Best TV Tonight: Wednesday 3 September 2025
It’s a bumper night for midweek television, with big-name presenters, emotional real-life stories, and one of Britain’s most enduring property series all competing for your attention. From tropical reality TV to hard-hitting documentaries and extraordinary builds, here’s what’s worth watching tonight.
Stranded On Honeymoon Island
📺 BBC One and iPlayer, 9pm
Davina McCall fronts one of the most talked-about new shows of the autumn, bringing a bold twist on the relationship experiment genre. From the makers of Married at First Sight UK, Stranded On Honeymoon Island sees twelve singles speed-date, marry, and then immediately jet off to a deserted tropical beach.
There’s no phones, no distractions, just their brand-new spouse and the vast ocean. The couples must figure out if chemistry can turn into commitment – and if it all falls apart, they can literally send up a flare to call time. Tonight’s opener introduces the first three couples, but one duo’s romantic adventure is threatened before it’s even begun, as a ghost from the past comes crashing in.
Long Lost Family: The Mother and Baby Home Scandal
📺 ITV1 and ITVX, 9pm
Davina McCall takes on a very different role over on ITV, alongside co-host Nicky Campbell, for a powerful return to one of the most moving factual strands of recent years. This two-part special, originally launched in 2011, investigates the harrowing legacy of mother and baby homes that operated across the UK, where unmarried mothers were hidden away and their babies taken from them.
In tonight’s episode, Jean, who was sent to the Home of the Good Shepherd in Surrey as a teenager, begins a search for the daughter she was forced to give up. Meanwhile, sisters Viv and Julie try to trace their older sibling on behalf of their mother, Margaret. Emotional, raw, and deeply important viewing.
Grand Designs – New Series
📺 Channel 4, 9pm
Kevin McCloud returns for the landmark 25th series of Grand Designs, and the show wastes no time diving into one of its most ambitious projects yet. Howard and Sarah dream of a futuristic floating home on a tidal estuary near Worthing – sleek, metallic, and boat-like in its design, but sitting on an experimental polystyrene base meant to withstand dramatic shifts between high tide and low mudflats.
The couple have £385,000 and an 18-month timeline, but face huge challenges from day one, including removing a giant WWII landing craft before any building can begin. With the unpredictable tide wreaking havoc on construction, and much of the engineering being designed on the fly, it’s the perfect recipe for the kind of high-stakes drama Grand Designs fans love.
