Britain’s Most Extreme Weather (Channel 4/HD | 8:00pm to 9:00pm | Monday 5th May 2014)

Alex Beresford trawls through centuries of British history and analyses the latest scientific research to find out if our winters are going to get colder. A combination of first-hand testimonies and astonishing homemade footage reveal the dangers of our recent cold snaps. Alex discovers how freezing weather can shut down the transport network, kill livestock and present hazards to anyone caught out in the cold. He experiences the dangers of freezing winds when he endures a wind chill that takes temperatures down to minus 50. Alex examines the severe winter of 1962/63: the coldest in over 200 years, when Britain was hit by temperatures below minus 20, and 80mph winds. The snow lay on the ground for a record-breaking 62 consecutive days and January 1963 was the single coldest month of the 20th century.

Watermen: A Dirty Business (BBC 2/HD | 9:00pm to 10:00pm | Tuesday 6th May 2014)

Series focusing on the men and women who take our calls, come to unblock the drains and keep the sewage flowing. This episode showcases the battle against time, as United Utilities deal with the ageing water grid. In Blackpool, Andy and Terry deal with an ancient collapsed sewer which has caused a pavement to subside before tackling a rather pungent blocked sewer. A 40-year-old water main in Cheshire bursts, leaving two thousand irate villagers without water. Meanwhile in Rochdale, waste water team Adrian and Wes investigate a blocked Victorian sewer which is overflowing onto a main road. However, it is a learning curve for some as the aqueduct which supplies Manchester’s water supply is turned off for the first time in 60 years to check for repairs. It is a jaw-dropping thought that the 4,000 men who originally built the tunnel had none of the technology team have nowadays, a testament to the skill and engineering we still rely upon today.

Creating the Kelpies (BBC 2 Scotland & BBC iPlayer only | 9:00pm to 10:00pm | Tuesday 6th May 2014)

Documentary following Glaswegian sculptor Andy Scott as he works on The Kelpies, two 30m-high horse heads made of steel, which now stand alongside the Forth and Clyde Canal. This film, narrated by Andy himself, follows the long and tortuous process of creating these 300-tonne sculptures, from design to installation. The enormous technical challenge involved engineers in Leeds, steel mills in Hartlepool and Corby and metal benders in Tipton, and was nearly derailed by the financial crisis of 2008. Originally planned to form part of the canal lock mechanism, the sculptures are now a free-standing attraction within Falkirk’s Helix Park.

In Horsham, parking campaigners Mike and Matt use their own money to buy tickets for motorists when theirs run out of time. In Islington, London, the Black Beret, a masked parking campaigner, is taking the council to court over the wording on its tickets – if he wins, it could mean that the council will have to pay £90 million back to motorists.

In this episode, Heston discovers that British curry house classics such as bhuna, vindaloo, phal, onion bhaji and the most famous of them all, chicken tikka masala, were all invented in Britain.
