How do third-party top-ups work if you want a more expensive care home?
Where a council funds a care placement, it must offer at least one home that meets the assessed needs within its own rate. A third-party top-up pays the difference for a more expensive home, and two conditions catch families out: the resident generally cannot pay it themselves, and the commitment lasts for the whole of the stay.
- The council's duty: at least one suitable home must be available within its rate.
- Who pays: a third party — a relative or friend — not usually the resident.
- The duration: for the length of the stay, not a fixed term.
- The risk: if the top-up stops, the resident may have to move.
01 What the council has to provide
A council arranging care must be able to offer at least one placement that meets the assessed needs at its own rate. If no such home is available, the council has to meet the higher cost itself — a top-up cannot be used to cover a shortfall in the council's own rate.
That is the right families most often fail to exercise. Where the only homes presented are above the council rate, the correct response is to ask which placement the council is offering within its rate, in writing. The answer establishes whether a top-up is genuinely a choice or a shortfall being passed on.
The assessed need is the reference point rather than preference. A home closer to family, with a nicer garden or a private bathroom, is a preference; a placement that cannot meet the assessed needs is not an offer at all.
02 Who can pay it, and for how long
A top-up is normally paid by a third party — a relative, friend or charity — rather than by the resident. The resident can pay it themselves only in specific circumstances, principally under a deferred payment agreement or during the twelve-week property disregard.
The agreement is with the council, not with the home, and it runs for the length of the stay. That is the commitment people underestimate: a top-up of £150 a week over five years is nearly £40,000, and it increases whenever the home raises its fees.
If the top-up stops being paid, the council reassesses and the resident may have to move to a placement within the council rate. Moving a frail older person between homes is a serious event, which is why the affordability of a top-up should be judged over years rather than months.
Shows: the total cost of a third-party top-up over the length of a stay, including annual fee increases. Ignores: any change in the council's rate, the resident's own contribution, and whether a placement within the rate is available.
On the defaults above, the worked example shows £43,100. By the final year the top-up is £191 a week, against £150 at the start — the commitment grows with the home's fees.

03 Before you agree to one
Ask three things in writing. Which home is the council offering within its rate? What exactly is the weekly difference? And how, and how often, will the top-up rise? A written agreement setting out the review mechanism is far better than a verbal assurance that increases are unlikely.
Then test the commitment against the payer's own long-term position. A son or daughter funding a top-up out of income has to be able to sustain it through their own redundancy, retirement or illness, and the person who bears the consequence of a failure is the resident.
Where the resident owns property, a deferred payment agreement can fund the top-up from the eventual sale rather than from a relative's income, and the property disregard rules decide whether that route is open.
Two questions, both in writing. Which home are you offering within your rate? And how will the top-up rise? Families are routinely shown a shortlist that is entirely above the council rate, agree a top-up in a difficult week, and discover four years later that it has grown by half and there is no way to stop paying it without moving their parent. The council's duty to offer something within its own rate is real. Exercise it before deciding, even if you then choose to pay more.
FAQ
Can I pay a top-up for myself?
Usually not. Top-ups are normally paid by a third party, with narrow exceptions — principally under a deferred payment agreement or during the twelve-week property disregard. Otherwise the resident cannot fund their own top-up.
Does the council have to offer a home within its rate?
Yes. At least one placement meeting the assessed needs must be available at the council's rate, and if none is, the council must meet the higher cost itself. A top-up cannot be used to cover a gap in the council's own rate.
What happens if the top-up cannot be paid any more?
The council reassesses, and the resident may have to move to a placement within the council rate. That is why the affordability of a top-up should be tested over the likely length of the stay rather than the first year.
