Hi folks, hope you all are well.
I've been asked to replace 3x battens fittings (6ft) to smaller fittings (4ft) in a office.
I reckon I can get them all fitted in 1.5 hours easily.
How much would you charge? Job is in Oldham. The location is only 8 minutes drive.
Thank you.

Hi all,

Hi All,
I went up to look at a small office room that has three t5 54w light fittings. Each fitting is a double. The lights turn on and strike immediately. Once they are on the will slowly dim down then slowly go bright again ever once in a while (not flickering and light is equal along...
