Update: read a further statement from Cllr Jayne McCoy, Deputy Leader and Chair of the Housing, Economy and Business Committee, London Borough of Sutton.
We can confirm that there was a fire at Chaucer House earlier today (Friday 20 July).
The fire did not spread and was not related to the cladding of the building. No injuries have been reported, though two adults were treated for smoke inhalation.
The building’s communal fire alarm worked as it is designed to - which is to alert the fire brigade and not to sound in all flats. The sprinkler in the flat was triggered and worked effectively. The fire was fully extinguished by 11.30am.
Steve Tucker, Managing Director of Sutton Housing Partnership, said: "We're enormously grateful to the fire brigade and the emergency services for their response to the fire at Chaucer House.
"Thankfully, the fire was contained and no one was injured. Our main concern now is making sure residents continue to get the support they need.
"We are hopeful that everyone at Chaucer will be able to return to their homes later today, but we are working with our partners to ensure temporary accommodation is available should anyone need it.
"Our staff will stay at Chaucer this afternoon and this evening as we work with LBS and the fire brigade to provide information and reassurance to anyone affected. Residents affected by the fire can come to Milton House, where tea, coffee, food, milk and nappies are available and staff are on hand to provide support."
The Leader of Sutton Council, Cllr Ruth Dombey, said: "Thankfully there were no injuries and the fire was contained to one flat and did not spread. The sprinkler system worked very effectively to contain the fire.
"Our huge thanks to the fire brigade and emergency services for their rapid response.
"A meeting was held earlier this afternoon with representatives of London Fire Bridge and Sutton Housing Partnership in order to reassure residents and provide support.
"We are hoping that everyone will be back into their properties later, but are preparing temporary accommodation and general assistance for a small number of residents.
"Fire investigators are working to establish the cause of the blaze but it was not related in any way to the cladding system."
