In 2025, parents and family members contributed to about half of all first-time buyer purchases in the UK, either through outright gifts, loans, or acting as guarantors. That figure is a direct reflection of how difficult it has become to accumulate a deposit independently when house prices remain high relative to starting salaries in most parts of the country. For many first-time buyers, family support is not a shortcut. It is the only realistic route onto the ladder. But the process of gifting a deposit is more involved than simply transferring money, and parents who approach it without the right preparation can inadvertently slow or complicate the purchase at a critical stage.
What mortgage lenders require
Every mortgage lender will ask about the source of a buyer's deposit, and where any part of it comes from a family member, they will require a formal gift letter. This is a signed document confirming that the money is a gift rather than a loan, that no repayment is expected or required, and that the person providing the funds has no interest in the property being purchased. Lenders are required by regulation to verify the source of deposit funds as part of their anti-money laundering obligations, and an informal transfer with no accompanying documentation will not satisfy that requirement.
The gift letter must typically include the full names and addresses of both the donor and the buyer, the amount being gifted, a clear statement that it is a gift and not a loan, confirmation that the donor has no stake in the property, and the donor's signature. Many lenders also require evidence of where the funds originated before they were gifted, which means the parent may need to provide their own bank statements showing the money leaving their account.
It is worth asking the mortgage broker or lender exactly what documentation is required at the outset to avoid delays later in the process.
Is it a gift or a loan?
This distinction matters more than some parents initially appreciate. If a parent intends to be repaid, even informally and without a written agreement, this constitutes a loan in the eyes of a mortgage lender, not a gift. A loan affects the buyer's affordability assessment because it represents an ongoing liability, and declaring it accurately is a legal requirement. Misrepresenting a loan as a gift on a mortgage application is mortgage fraud, a serious matter with significant consequences for both the buyer and the parent involved.
If a parent wants to provide funds as a loan rather than a gift, this needs to be declared to the lender, who will factor the repayment into their affordability calculation. Some lenders will not accept gifted deposits from parties other than immediate family members, and a small number will not accept them at all for certain products. Checking the specific lender's policy early in the process, rather than assuming all lenders treat gifts identically, is an important step.
Tax considerations for parents
Gifting money to a child is generally straightforward from a tax perspective, but there are details you should be aware of. In the UK, an individual can give up to £3,000 per tax year free of inheritance tax under the annual exemption. Amounts above this may be subject to inheritance tax if the donor dies within seven years of making the gift, under the potentially exempt transfer rules. The seven-year threshold is the key figure: if the parent survives for seven years after making the gift, no inheritance tax applies regardless of the amount.
For gifts that are part of normal expenditure from income rather than capital, additional exemptions may apply, but these are assessed on a case-by-case basis. Parents gifting significant sums from savings, inheritance, or the proceeds of a property sale should consider taking brief advice from an accountant or solicitor to ensure the gift is structured in a way that is tax-efficient for their estate.
Timing and the mortgage process
The timing of a gifted deposit matters practically. Mortgage lenders will request bank statements covering typically the past three to six months, and a large unexplained transfer into a buyer's account during that period will require explanation. The cleanest approach is to transfer gifted funds in good time before the mortgage application, ideally several months in advance, so that the money is clearly visible as an established balance rather than a recent arrival. Where this has not happened, a clear paper trail showing the gift, accompanied by the required letter, will still satisfy most lenders, but it requires prompt and organised documentation.
What parents should consider before committing
Gifting a significant sum to a child is an irreversible financial decision, and parents should feel confident in their own financial security before doing so. Retirement savings, pension provisions, and the potential costs of care in later life are all relevant considerations. A gift that stretches a parent's own finances in ways they have not fully considered is rarely in anyone's long-term interest. The conversation between parent and child should cover not just the practical mechanics of the transfer but the broader context of what both parties can realistically afford.
Done with proper preparation, a gifted deposit is one of the most meaningful and commercially straightforward ways a parent can support a first-time buyer. Done without it, it introduces delays and complications into a process that is already demanding enough.
