The Chancellor is expected to announce a £126million boost for traineeships when the Budget is revealed on Wednesday.
Rishi Sunak will tell MPs that 40,000 additional traineeships will be created with the cash injection.
He will also increase the cash incentives for employers who take on an apprentice to £3,000.
The age of the apprentice won’t factor in to whether employers will be eligible for it.
At the moment, businesses can claim £2,000 for each new apprentice they hire that is between the ages of 16 and 24.
If they take on an apprentice aged over 25, they get £1,500, so the new boost will double the incentive.
The Chancellor is also expected to set out plans for new “flexi-job” apprenticeships.
Under these, trainees will develop their skills with a range of different employers within a particular sector.
The apprentices will be linked to an agency rather than an employer, who will place them in various relevant organisations.
Employers will be able to bid for money from a £7m pot to create new agencies from July.
The first apprenticeships are expected to start in January 2022.
Sectors with flexible working patterns, such as the film and TV industries, are likely to benefit from the scheme, ministers believe.
Rishi’s announcement comes amid worries that young people have been particularly badly affected by the economic fallout of the Covid-19 pandemic.
He said: “Our plan for jobs has spread opportunity and hope throughout the crisis, helping people back into work and harnessing their talents for the future.
“We know there’s more to do and it’s vital this continues throughout the next stage of our recovery, which is why I’m boosting support for these programmes, helping jobseekers and employers alike.”
