Bank of Mum and Dad – Savings Linked Mortgages

Many clients want to help their children onto the property ladder.

Not all of them are comfortable giving away large sums of money to do it.

This is where conversations often stall. There is a clear intention to help, but also a need to retain control, protect liquidity, and avoid unintended tax or planning consequences.

An increasingly common solution is the use of linked savings accounts, often referred to as Family Offset or Family Assist arrangements.

What Is a Linked Savings Mortgage?

In simple terms, a parent (or family member) deposits funds into a savings account linked to the child’s mortgage.

The lender uses those funds to reduce their risk.

In return, the child may benefit from:

• Improved affordability
• Lower interest rates
• Reduced deposit requirements

The key difference is this:

The money is not gifted.

Ownership remains with the parent / family member.

How It Typically Works

The structure is relatively straightforward, although lender criteria varies:

• The parent deposits funds into a lender held savings account
• The funds are usually locked away for a set period (commonly 3 – 5 years)
• The child takes out a mortgage with improved terms
• Once the mortgage reaches a target loan-to-value (LTV), the savings are returned

From a client’s perspective, this can feel like “helping without giving it away”.

The Key Considerations

While the concept is simple, the planning implications are not.

1. Control vs Access

Parents retain ownership of the funds, which is often the main attraction.

However, access is restricted for the agreed period.

This creates a trade off between control and liquidity.

2. No Inheritance Tax Benefit

As this is not a gift, there is no immediate inheritance tax (IHT) advantage.

For clients where estate planning is a priority, this may not align with wider objectives.

3. Risk Exposure

There is a degree of risk.

If the child defaults on the mortgage, the lender may have recourse to the linked savings.

This makes suitability and affordability even more important.

4. Opportunity Cost

This is often overlooked.

Those funds could otherwise be:

• Invested
• Retained within a business
• Used for tax planning strategies
• Gifted in a more structured way

For business owners and investors in particular, this becomes a meaningful discussion point.

5. Product and Lender Limitations

The market is still relatively niche.

That means:

• Limited lender choice
• Specific eligibility criteria
• Potential changes to product terms once the savings are released

Understanding how each lender structures these arrangements is key to avoiding surprises later.

Where This Fits in Holistic Planning

Linked savings mortgages sit at the intersection of:

• Mortgage advice
• Tax planning
• Investment strategy
• Estate planning

Used correctly, they can be a very effective tool.

Used in isolation, they can create unintended consequences.

This is why collaboration between advisers matters.

When Might This Be Suitable?

These arrangements can work well where:

• Parents want to help but are not ready to gift capital
• Liquidity is important
• There is a shorter term plan to reduce LTV (e.g. overpayments or natural repayment)
• Investment or business funds need to remain intact

They are less suitable where gifting, tax planning, or long-term estate structuring is the priority.

Final Thoughts

Helping the next generation onto the property ladder is rarely just a mortgage conversation.

It is a financial planning decision.

Linked savings arrangements offer a middle ground between doing nothing and giving money away, but they come with trade-offs that need to be understood.

If you have clients exploring this route, a joined up conversation across mortgage, tax, and financial planning can make a significant difference to the outcome.
