The move will also help to build and connect customers to its new future-proofed ultrafast Full Fibre broadband network.
The recruitment drive includes 2,500 full-time jobs in Openreach’s service and network build divisions, and an estimated 2,800 positions in its UK supply chain.
The company also announced a commitment to upgrade its 27,000 Openreach vehicles – the second largest commercial fleet in the UK – to electric by 2030.
Openreach announced it has hit a record build rate for its Full Fibre broadband programme, which aims to reach 20 million homes and businesses by the mid-to-late 2020s.
Openreach said its engineers are delivering faster, more reliable connectivity to the equivalent of a home every 15 seconds.
Openreach chief executive Clive Selley, said: “As a major employer and infrastructure builder, we believe Openreach can play a leading role in helping the UK to build back better and greener.
“Our Full Fibre network build is going faster than ever and we’re now looking for thousands more people to build a career with Openreach and help us upgrade broadband connections and continue improving service levels.
“We’re also investing in our supply chain, which will support the creation of thousands of jobs based all over the UK.
“We know the network we’re building can deliver a host of green benefits, from consuming less power to enabling more home working and fewer commuting trips.
“We’re going to take that a step further, by committing to build and maintain that network using state of the art electric vehicles across our 27,000-strong fleet.”
Chancellor Rishi Sunak said: “Throughout this crisis I’ve been clear that our number one economic priority is to protect jobs so I’m delighted to welcome this announcement of 5,000 new skilled roles.
“We’re investing billions of pounds across the UK as part of our Plan for Jobs to ensure nobody is left without hope or opportunity.”
