Hi OP
I’m really sorry things are so stressful right now. I specialise in homelessness law, so here are the key points that might help alleviate your concerns. The below assumes that you are eligible for homelessness assistance - you will be so long as you are not a migrant with a form of leave that means you do not have recourse to public funds.
Prevention duty
If you’re at risk of homelessness within 56 days, the council will owe you a prevention duty. Under this they must create a personalised housing plan setting out what they will do and what you need to do to prevent you becoming homeless. You don’t have to wait until the exact 56‑day mark, you can ask for help earlier, especially where there is vulnerability in the household. Vulnerability does not* *mean your children should be removed; it means the council should act sooner and take into account what steps you will be able to take.
This duty is owed irrespective of whether you are or are not, homeless intentionally.
The Homelessness Code of Guidance is very clear: families should not be left until the eviction/bailiff stage before help is given. That leads to CCJs, costs, and long‑term damage to your ability to rent, not to mention the impact on your wellbeing. If the council tries to delay you until the last minute, challenge it.
Homelessness due to unfit accommodation
A person is legally homeless if their home is not reasonable or safe to occupy. Ongoing damp and disrepair that hasn’t been resolved may mean your property is not fit to live in. You might want to explore that.
Relief duty and temporary accommodation
If your notice expires before you find somewhere to live or the council accepts that your home is not fit to occupy, you will be homeless and the council will owe you a relief duty. Under that they must provide temporary accommodation as long as you are eligible for assistance and in priority need. You will be in priority need because you have children in your household.
Whether you are intentionally homeless does not matter at the relief stage. They accommodate first, then investigate.
Main housing duty
If you haven’t secured accommodation by the end of the relief duty and the council decides you are not intentionally homeless, they will owe you what is often termed referred to as the main housing duty. that is a duty to secure you settled accommodation. This could be private rented or social housing. Make sure you’re on the social housing register; homeless households get reasonable preference whether or not they’re found intentionally homeless.
Fault‑based eviction and intentional homelessness
Just because your landlord has served a fault‑based notice does not mean the council will accept it at face value. They must investigate themselves, and it’s for them to prove intentional homelessness, not for you to disprove it.
From what you’ve said, it sounds unlikely they would find you intentionally homeless. And if the landlord is selling anyway, you would have been in the same position regardless of any alleged fault so it will be difficult for the Council to come to a view that you are. I doubt very much they will even look into it.
I the unlikely event that the council did find you intentionally homeless, it must allow you to remain in temporary accommodation for a reasonable period to secure alternative accommodation. I would also appeal if they do.
Temporary accommodation
Temporary accommodation is not always ideal. Some councils are extremely stretched and do end up placing families in B&Bs for longer than the statutory limit even though they shouldn’t. Because of this, some households choose to stay put until the landlord reaches the eviction/bailiff stage, or they move in with family/friends if that’s an option.
However, don’t let that put you off asserting your rights. If you need temporary accommodation the council has a legal duty to source suitable temporary accommodation, not just anything available. You are entitled to ask them to act proactively, not passively, and to secure accommodation that meets your household’s needs.
Social services
A duty to refer to social services is a safeguarding measure. Children must never be left homeless i.e. on the streets or in unsuitable accommodation. You will be entitled to temporary accommodation so will not be street homeless.
Even if there were a finding of intentional homelessness (unlikely), that would not of itself cause social services will remove your children. Social services only intervene where there are additional safeguarding concerns, for example, if a child is being neglected, is unsafe, or a parent is unable to care for them.
Where families are eligible for assistance, social services usually have no role beyond basic safeguarding checks due to the fact that a duty will be owed to provide temporary accommodation.
To provide some reassurance, in cases where families have no recourse to public funds and are not entitled to homelessness assistance, social services typically accommodate the whole family together if they would be homeless otherwise. Separating a family is not in the best interests of the child and likely a human rights breach. Unless, as I say, there are other issues. The family is accommodated under s.17. Section 20 applies where a child becomes looked after.
