Saffron Building Society contractor mortgage lending criteria
Saffron Building Society is a specialist lender with a strong reputation for supporting contractors. It understands contractors’ financial situations, circumstances, income structures and their specific requirements.
Saffron also offers later-life lending, Joint Borrower Sole Proprietor (JBSP) mortgages, and manual underwriting for applicants with credit challenges.
Key mortgage lending criteria
Before addressing the specific criteria by contractor type, these are the overarching criteria for all applicants:
- Minimum age: 21;
- Minimum loan term: five years;
- Deposit: maximum loan = 90% LTV (minimum 10% deposit);
- Interest-only options: available up to 70% LTV, subject to an acceptable repayment strategy.
Loan sizes:
- Minimum: £100,000;
- Maximum: £3,000,000 up to 80% LTV, or £1,000,000 up to 90% LTV.

Day-rate, fixed-term and umbrella payroll contractors
Saffron accommodates both fixed-term and short-term contractors in its “contractor” range. The lender has neither industry restrictions nor minimum income requirements for day rate contractors.
Applicants need only three months’ contracting history at time of application. However, they must back that up with a further two years’ experience in the same industry. Contractors will need to provide a CV as evidence of that experience. Underwriters will also consider gaps between contracts in their assessment process.
Saffron also considers day-one contractors, but solely on a discretionary basis. To begin any enquiry, the new contractor must have at least one year’s work experience in their contracting sector.
Income assessment
Saffron’s income assessment calculation is:
- Day rate (£) x days worked per week (max 5) x 48 weeks (per annum)
Underwriters will then apply its relevant multiplier to confirm the applicant’s mortgage affordability.

Construction Industry Scheme (CIS) workers
Saffron’s improved lending criteria for CIS contractors now see the lender on par with other lenders.
Its criteria are now:
- Income (for affordability purposes): the average determined by the last three months’ payslips;
- Experience: one year in the construction industry;
- Evidence: three months’ payslips and bank statements;
- Deposit: max. 90% LTV (min. 10% deposit).

Zero-hours contract workers
Saffron will use 100% of a zero-hour contractor’s income, providing they have at least 12 months’ zero-hour contracting experience. This experience can be with different employers.
Saffron Building Society’s underwriters need evidence of the contractor’s income, too. The applicant must provide their:
- latest P60;
- last three months’ payslips;
- last three months’ bank statements.
In addition, the applicant must have at least a 10% deposit (90% LTV mortgage).
The lender will also consider joint applications where both applicants are zero-hour contractors. If so, the lender will use 75% of the second applicant’s income, providing they have at least nine months’ experience as a zero-hour contractor.
