The deal between the Building Engineering Services Association and Unite follows a four year pay rise for electricians worth 10.25% which was agreed earlier this week.
The latest BESA National Agreement will see further negotiations later this year to agree wage levels that will apply for the two years from September 2018.
Unite initially requested a four-year agreement from October 2016 with significant increases to wages and benefits.
But employers argued that a two-stage agreement and a stepped increase were more appropriate in the current economic climate.
Peter Rimmer, BESA director of employment and skills said: “We enjoyed our usual robust but constructive negotiations with Unite this year.
“Needless to say, the union argued hard for a considerably higher hourly rate, but accepted that the compromise reached was fair and in the long-term interests of both employers and operatives.
“As we enter a period of economic uncertainty following the EU referendum, it is important that businesses can plan for the future safe in the knowledge that labour costs will be maintained at a sustainable level, while also providing operatives with a fair return for the vital skills they provide to
the industry and its clients.”
