The firm has 150 clients through Cambridgeshire County Council, another 15 through Central Bedfordshire Council and eight more in the Sandy and Biggleswade area who are self-funded.

In a letter to clients sent on 25 October, seen by the BBC, the company said "the operation has become unsustainable in the last recent months"...

TJ Jimenez, a senior healthcare worker and one of Oscar's carers, has worked for the company for 18 months but said communication about the closure had not been clear.

"It was very shocking. I received a phone call from the office and told we had 28 days and the company is closing. So at first it doesn't sink in yet, [I thought] 'Is this really real?'"

Staff then received an email but it gave no specifics, and getting information from the company's office had been difficult, he said.

"We're in a very difficult situation because we have to find jobs, especially as I'm a family man. I need continuity of income," he said...

Public service union Unison said it was "supporting a large number of members who work for Beaumont Healthcare", many of whom were in the UK on work visas.

Cambridgeshire branch secretary Robert Turner said it was "terrible" that more than 100 staff would need to search for new jobs...

A spokesman for St Neots-based Beaumont Healthcare, which has been operating since 1996, said it was "with great sadness that we have now to end our contracts as it has become unsustainable within the financial constraints to continue"...

It said it was working to ensure a "safe handover of care to other care providers" and assisting staff to transfer to other agencies and find new work.
