Carbon Monoxide Poisoning Scare Leads to Evacuation of Hackney Tower Block

More than 120 residents were forced to flee their homes in the early hours of Tuesday morning after dangerously elevated levels of carbon monoxide were detected in a 14-storey tower block in Hackney, prompting a major emergency response and renewed calls for urgent boiler safety inspections across the capital's ageing social housing stock.

The alarm was raised at approximately 2.15am at Pembury Heights on the Pembury Estate, when a resident on the ninth floor reported feeling dizzy and nauseous. London Fire Brigade crews arrived within minutes and immediately detected carbon monoxide readings that were, according to one officer, "well beyond anything we would consider safe for habitation."

Four fire engines, six ambulances, and specialist hazardous materials teams were dispatched to the scene. Residents — many of them elderly or families with young children — were evacuated in their nightclothes into the biting cold, with temporary shelter provided at the nearby Clapton Park Community Centre.

Source of the Leak Traced to Faulty Communal Boiler

Investigators confirmed later that morning that the source of the leak was a malfunctioning communal gas boiler located in the basement plant room. The unit, installed in 2011, had not been serviced since early 2024, despite Hackney Council's obligation to carry out annual safety checks under the Gas Safety (Installation and Use) Regulations 1998.

"This was an entirely preventable incident," said Station Commander Laura Betts of London Fire Brigade. "Carbon monoxide is an invisible, odourless killer. Had that resident not woken when she did, we could very easily be looking at fatalities this morning. The fact that a communal boiler in a building of this size went unserviced for over two years is deeply troubling."

Residents Describe Panic and Confusion

Fatima Osei, 74, who has lived on the estate for more than three decades, said she was woken by neighbours banging on her door. "I didn't hear any alarm — nothing," she told this publication. "My neighbour Doris was shouting through the letterbox. I grabbed my coat and came down the stairs in my slippers. There were children crying, people confused. Nobody from the council was there for hours."

Another resident, who asked not to be named, said he had complained to Hackney Council about a "strange smell" in the communal corridors on multiple occasions over the preceding months. "I reported it in January, then again in March. They sent someone round who said it was probably just the bins. I knew it wasn't right," he said.

Council Faces Difficult Questions

Hackney Council confirmed in a statement that an urgent review of gas safety compliance across its entire housing portfolio had been launched. A spokesperson said: "The safety of our residents is our absolute priority. We are working closely with the Health and Safety Executive and London Fire Brigade to establish exactly what happened and to ensure it cannot happen again. All affected residents have been offered temporary accommodation."

However, housing campaigners were quick to point out that this is not the first time the borough has faced scrutiny over maintenance failures. In 2023, a coroner's report following the death of a tenant in Stoke Newington cited "systemic failings" in the council's approach to gas safety inspections.

A Wider Problem Across London

The incident has reignited a broader debate about carbon monoxide safety in London's social housing. According to figures from the charity CO Research Trust, there are an estimated 4,000 carbon monoxide incidents requiring hospital treatment in England each year, with a disproportionate number occurring in older housing stock common across the capital.

The Health and Safety Executive confirmed it had opened a formal investigation into the Pembury Heights incident and would be examining whether Hackney Council had met its legal obligations as a landlord. Residents were permitted to return to the building on Wednesday evening, though several families have reportedly refused to move back in until independent safety assurances are provided.
