RESIDENTS living on a millionaire-owned estate may have been exposed to a “massive leak” of carbon monoxide after complaints about the smell of gas were “ignored,” campaigners have claimed.

One person was hospitalised after reports were made of a carbon monoxide leak from temporary boilers on Tuesday at Dorchester Court in Herne Hill, London Renters Union (LRU) said.

A fire crew, paramedics and gas engineers were called to the site and two other people were treated at the scene at around 3pm. 

Carbon monoxide is odourless, but residents say that they had raised concerns with the building’s manager, Property Partners, about smelling gas in the days before October 20, and the agency had not sent engineers to check the temporary boilers, which may have been faulty. 

The private housing estate of 300 residents is owned by property tycoon Heinrich Feldman – listed in the Sunday Times rich list –through his business Manaquel. 

Charlie, a member of LRU living at Dorchester Court, said: “It feels awful knowing that our landlord is worth millions but is dragging his feet on even the most basic investment to protect our lives during a global pandemic. 

“Knowing we could have died and that we’ve been shouting about these problems for years and been ignored makes my blood boil.” 

Rosa, a spokesperson for the LRU, said the agency “reacted with total callousness” and accused it of “exposing tenants to an unbelievably dangerous situation.” 

Property Partners deny that there was a major gas leak at the estate. The agency claimed that engineers in charge of the temporary boilers, who came to the site at 3pm, said carbon monoxide levels were at an acceptable level, and that the issue was resolved by 5pm. 

Tenants have long complained about the dilapidated condition of the estate, and held a protest earlier this year over ongoing problems with the heating system.
