When you're working in the NHS, Armed Forces, or local authority, getting on the property ladder can feel like an uphill battle. Many public sector workers find that their salary alone isn't enough to secure a mortgage in most UK regions. With the average UK property valued at £273,000 and house prices continuing to outpace salary growth, you might be wondering whether involving a family member as a guarantor could unlock homeownership.
Understanding how guarantor mortgages work
A guarantor mortgage allows a family member to agree legally to take responsibility for your repayments if you fall behind. Your guarantor typically needs to be a homeowner with substantial equity in their property or significant savings. They won't own any share of your home or appear on the title deeds, but they're adding their financial security to your application.
This arrangement works in your favour because lenders view your application as lower risk. When you're a teacher earning £26,000 annually or a nurse on £25,000, traditional lending criteria might only offer you a mortgage of around £130,000. With a guarantor backing your application, you could potentially access higher loan amounts.
When guarantor mortgages make sense for public sector employees
While public sector workers typically have stable employment and strong pension schemes, these factors don't always overcome the affordability gap. Saving a deposit remains one of the biggest barriers. In December 2025, 22% of first-time buyers put down deposits of less than £20,000, demonstrating how challenging it is to accumulate substantial savings on a public sector salary.
A guarantor bridges this affordability gap by providing additional financial backing that reassures lenders you can manage the repayments, helping you get on the property ladder with a smaller deposit than standard mortgage products require.
Considering the risks involved
Before asking your parents or relatives to act as guarantors, you need to understand the serious implications. If you cannot make your mortgage payments and your guarantor also fails to cover them, both your home and your guarantor's property could be at risk of repossession. This creates significant emotional and financial pressure on family relationships.
Your guarantor's own borrowing capacity will be affected while they're supporting your mortgage. If they still have their own mortgage, lenders will assess whether their income can cover both sets of payments. They'll also need to obtain independent legal advice before signing any agreements, which adds legal costs to the process.
