The threat of strike has been in the air for weeks.
88.9% of Bectu union members at the BBC who work for Siemens voted to accept the pay offer.
A £300 consolidated pay rise backdated to January was agreed. The deal will also see futher negotiations.
This will avert potential strike action which could have seen TV coverage the general election build up disrupted.
Suresh Chawla, national officer at Bectu, said: "We are very pleased to have averted the need to take industrial action. Whilst the offer falls short of our initial claim we believe it's the best settlement that can be reached through negotiation alone and we look forward to the increase being included in our members next pay packets'.
