One of Danny Cohen’s final season commissions as controller of BBC1 is a look at the cost of living through five single docs, a two-parter and a Watchdog spin-off series.

The season is expected to air across two weeks this summer at 9pm and 10.35pm.

Rising food costs will be a major focus, with Optomen’s BBC2 show The Great British Menu moving to the flagship channel for a 60-minute special. The Great British Budget Menu (w/t) will challenge chefs James Martin, Richard Corrigan and Angela Hartnett to create a banquet on the sort of budget on which struggling families have to feed themselves.

RDF Television is making the 60-minute Eat Well For Less?, which teams MasterChef’s Gregg Wallace with new talent Chris Bavin, who is also a grocer. The show will contrast a high-end and budget version of a fish-and chip supper and ask questions about food production and consumer issues.

Your Money Their Tricks is a 4 x 60-minute consumer series made by the BBC in-house Watchdog team. It will tackle the motor, travel, entertainment and retail sectors, and show consumers how to avoid being caught out.

“If you’ve ever wondered if your car really needed that expensive work, keep watching,” said commissioning editor, factual features & formats, Alison Kirkham, who ordered all three shows.

Commissioning editor for documentaries Charlotte Moore has ordered four single docs. Nick & Margaret – Benefits: How Much Is Enough? (w/t) will challenge four benefit claimants and four taxpayers to explore each other’s lives, and then agree on what level of benefit is fair. The 2 x 60-minute show is made by Silver River Productions.

The other three docs are Blakeway North’s 40-minute ob doc My £9.50 Holiday, about families taking advantage of newspaper offers for super-low-cost breaks; RDF TV’s 45-minute Auctioneers And Dealers (w/t), about lost and relinquished goods being auctioned off; and Blast! Films’ Landlords (w/t), which charts the sometimes fraught relationship between tenants and landlords from both perspectives.
