Questions remain over who will foot the bill for patients transferred from a medium secure mental health unit that was destroyed in a fire.

When flames swept through Chase Farm Hospital in north London last week, 67 patients had to be evacuated. All but 22 inpatients have been moved to other parts of Barnet, Enfield and Haringey Mental Health trust, while 17 are being treated by independent providers and others are at Oxleas foundation trust in Kent.

Barnet, Enfield and Haringey is negotiating with local commissioners over who will pay for the transferred patients.

Early talks

North London Forensic Service director Janet Alldred said they were in "initial discussions" and did not yet know what the bill would be.

Around 100 firefighters tackled the blaze, the cause of which is being investigated. Associate medical director Frank Farnham said the evacuation had been "a great success".

Due to a lack of medium secure beds, 10 patients have been placed in low secure units. Dr Farnham said: "We may have sacrificed a little in the height of fences but we kept the same clinicians, which is important to these patients."
