Being a supply teacher shouldn't mean being locked out of homeownership. While your employment pattern might look different from permanent staff, you have more mortgage options than you might think.
The challenge supply teachers face
Traditional lenders often view supply teaching as high-risk due to the irregular nature of work. Your income might fluctuate between assignments, and you may not have the employment history that conventional mortgage criteria typically require. However, the mortgage landscape has evolved in recent years, and specialist lenders now recognise the value and stability that experienced supply teachers bring.
Specialist lenders who understand your role
Teachers Building Society specifically caters to education professionals and requires only evidence of working in your intended purchase region for two academic terms. They process applications by hand, assessing each case on its merit rather than relying solely on automated systems, and will even accept future employment contracts before you start work, particularly beneficial for Early Career Teachers beginning in September.
Income requirements and documentation
Most lenders use income multiples of 4.5 to 5 times your annual salary. For supply teachers, this calculation typically uses your average earnings over a 12-month period. You'll need:
- At least 12 months of bank statements showing regular payments
- Tax returns or SA302 forms if self-employed
- Agency contracts or employment letters demonstrating ongoing work
- P60 forms from previous tax years
Beyond standard payslips, consider compiling a portfolio demonstrating your commitment to teaching. Include agency registration certificates and letters of recommendation from schools where you've worked to showcase your professionalism and reliability.
If you’re a self-employed supply teacher, keep detailed records of expenses, as legitimate teaching costs can reduce taxable income and improve affordability calculations.
Improving your application success
Keep detailed records of all assignments and build relationships with schools for longer-term contracts. Joint applications can improve your chances, too. If you're buying with a partner in permanent employment, this can offset perceived risks associated with supply teaching.
Don't overlook guarantor mortgages where family members provide additional security, or shared ownership schemes that reduce initial financial commitment. Finally, consider timing your application when you have extended contracts lined up, as some providers will consider future employment.
Current market opportunities
The UK government's Mortgage Guarantee Scheme was available until 30 June 2025, allowing buyers to purchase properties up to £600,000 with just a 5% deposit. However, the current government has announced plans for a permanent replacement scheme in future, providing ongoing support for buyers with smaller deposits.
Professional guidance matters
