Offset mortgage

[Andy2022]

What you're asking though, is a different question.
Your family can give you as much as they want as a gift, which I don't believe HMRC treat as taxable income.
There is a £3k/year gift allowance per person (your parent) which is exempt from inheritance tax (IHT).
Above that, if they live for 7 years after the gift you're fine. If not, the gift may be subject to inheritance tax.
It's a fairly complex area so you should talk to a professional, and them about it.

AFAIK People can gift unlimited amounts providing it comes from income but agree the OP should talk to a professional

You can get family offset mortgages which does exactly as the name implies.

Family members retain their account as per usual but can be linked to the mortgage holder to provide them with the offset advantage. Goes without saying, the account holder does not earn interest, which is hardly a big deal.

Not exactly. You can set up a regular giving from your 'surplus income' without IHT but not give arbitrary one-off gifts. At least not when I looked into it 5-6 years ago. So you could support a wastrel nephew or fund someone through private education, etc.

For regular gifts, there’s a section on the IHT403 form Gifts Made as Part of Normal Expenditure out of Income where you list income and gifts year by year. I’ve been advised to keep this table maintained and accessible to a potential executor so that it stays outside of IHT in the unfortunate event
