The rate for a play over 70 minutes will rise to £8,952 this year, and £9,176 next year.
The writing rate for plays of between 30 and 70 minutes increases to £5,961 this year and £6,110 next year.
Shorter plays of under 30 minutes will be paid at a rate of £2,981 from 1 April 2018 and £3,056 from 1 April 2019.
Other increases include uplifts to royalty fees and thresholds, meal allowances, day rates and option purchases. All of these are detailed in the new rate card
WGGB General Secretary Ellie Peers said: “Theatre writers play an important role in the UK’s creative industries which are currently booming, worth £92 billion per year and growing at twice the rate of the UK economy. It is important playwrights are properly remunerated for their valuable contribution and this two-year deal guarantees a rising income until 2020.”
