SSE has become the latest utility to warn of a looming engineering skills crisis and a need to bring in more apprentices.

The Perth giant said around 50 per cent of the sector's workforce are due to retire by 2023 and 208,000 people need to be recruited to plug the gap.

ScottishPower recently made a similarly stark warning while Weir Group and engineering entrepreneur Jim McColl have also suggested there needs to be more done to get young people into the sector.

SSE said it was increasing its apprentice numbers by around 20 per cent having recruited more than 100 annually since 2007.

John Stewart, SSE director of human resources, said: "Apprenticeships put young people on track for a first rate career and with around 50 per cent of the sector's workforce set to retire by 2023, there is a need to invest now.

"We're boosting our apprentice numbers by 20 percent, investing £11.68m - an average of £80,000 per trainee - to recruit and train the workforce of the future. What's more, apprenticeship programmes work for the country as well as young people and business.

"Research we've carried out with PwC tells us for every £1 we spend on our apprenticeship programme the net economic impact on society is £4.29."

SSE said it has invested more than £64m in training in excess of 800 apprentices since 2007.

It offers apprenticeships lasting between three and four years in a number of different engineering disciplines which include electrical, mechanical, heating, overhead lines and gas.

Laura Sneddon, a 30-year-old Technical Skills Trainee (TST) with SSE's Power Distribution business (SSEPD), discovered the training scheme while browsing Twitter during a gap year in Australia.

She said: "The apprenticeship can take you anywhere - one day you might be out on a job and the next day you could be planning another, or learning about another part of the business.

"You spend time with jointers, liners and fitters, you undertake managerial-based placements and you spend around 13 weeks of the year studying for your degree."
