Lack of Carer's courtesy while in your property

You should contact the Agency and ask the carers' manager to deal with it.
If this doesn't help contact a different agency

How long are they contracted to be with you ? 12 minutes is no time to help care properly for someone especially if they are hiding in the bathroom on their phone? Why are they sitting outside doing nothing?

Please phone the agency and clarify what you can expect, especially the amount of time . Explain everything you have seen. I may be wrong but I would have thought you should have something in writing regarding their service/contract.

I feel for you it sounds horrendous hope it improves soon

Agree with both the above. Do mention ‘phone and car park time too.

* But what really upsets me, and perhaps I am being a little petty about it, that they all seem to want to use the bathroom for themselves before they leave (male & female) without ever having the courtesy to ask if I would mind first. *

They have just used your bathroom in the course of caring for your husband.

Of course , before leaving they must use the bathroom again "for themselves" to wash their hands; essential hygiene. I'd be shocked if they did not.

.

I agree with butterandjam about using the bathroom.

Is it possible they have to complete records of their visit on their phones? And look to see where their next visit will be?

Just some possible explanations of what you are seeing, but to be sure, contact the agency to find out exactly what you can expect.

But surely they would be wearing disposable gloves.

There should be a written contract specifying exactly what services they will provide and over what period of time. They should not be allowed to use their phones while on your premises unless in an emergency.

If there is not a written contract demand (not ask) demand one and then make sure it is fulfilled to the letter.

NICE states that home care agencies should ensure visits last at least 30 minutes.
Shorter visits (such as 15-minute calls) are heavily discouraged and should only occur in exceptional circumstances. Exceptions where shorter visits are permitted include:
Specific tasks: Short check-ins to ensure a service user has taken medication.
Safety checks: Quick visits to ensure an individual is safe and well.
Prior agreement: When the person receiving care (and their family) has.

If your agency is cutting visits short without your prior agreement and you are not receiving the care stipulated in your care plan, you should report this to your local care manager or the Care Quality Commission (CQC).
