More than 1,400 homes and stores have been plunged into darkness after a power cut in Brentford today (4).
People will be left in the dark for at least three hours tonight as Scottish and Southern Energy (SSE) say they hope to restore power by 8pm tonight.
Electricity went out at about 4.45pm.
People have been evacuated from several buildings in Brentford after a power cut today (4).
Our reporter was on site at the Watermans arts centre in Brentford when the lights went out in the area.
It is believed the problem is affecting part of the High Street from Watermans as far as Morrisons and up to Brentford station.
While trains are still believed to be stopping at the railway station the power cut is likely to cause chaos for commuters travelling after work tonight.
The main parade on High Street was reported to be unaffected.
People took to social media site Twitter to report what's happening.
Hounslow council also tweeted to tell followers: "Brentford housing office currently has no power. "Brentford High Street including the Hounslow Homes office have also experienced a power cut."
A spokeswoman for SSE said: "The power cut happened at 4.45pm.
"About 1,400 customers are without power due to a high power voltage fault.
"We have got engineers on route to the site at the moment (5.43pm).
