Sarah Rennie, 35 WILL MARTIN, 32

Wheelchair user Sarah Rennie must evacuate down 26 flights of stairs in the event of a fire after discovering cladding on her high-rise block is unsafe.

When she bought the flat, which she has adapted for her needs, the advice was to stay put. “It’s definitely impacting on my physical and mental health,” she told the

Mirror. “Emotionally I feel betrayed that I was mis-sold my flat.

“I also feel frightened that if there is a fire I am going to be the last one out – if I get out at all.”

The accessibility specialist has already received a £5,000 service charge bill for increased buildings insurance and a 24-hour waking watch.

She will also face a £53,000 bill for remedial works on her high-rise block in Birmingham, if their application to the Building Safety Fund is unsuccessful.

A week after the Grenfell disaster, Will Martin discovered that his building was covered in the same flammable cladding.

The 32-year-old junior doctor now faces a £52,000 bill for his share of £6.2million of remediation works at the development in Sheffield, which also has missing fire cavity barriers and failed insulation.

A 24-hour waking watch costs him £3,000, a year, eight weeks salary. He said: “To anyone who doesn’t live in one of these buildings you cannot convey the fear and anxiety that come from resting your head on a pillow meters away from flammable cladding.”

He challenged Boris Johnson and Housing Secretary Robert Jenrick to live a day in that position, adding: “I would say put yourself in our shoes for a day and see how it feels.”
