Deposit alternative specialists, flatfair, has announced the rollout of its new Tenant Guarantor product in partnership with residential real estate giant, Heimstaden, covering 1,000 Build-to-Rent (BTR) units over three sites.

The launch, in January next year, strengthens flatfair’s positioning as a one-stop shop for tenant onboarding admin, combining Tenant Guarantor with its No Deposit product to deliver a faster, cheaper and more frictionless move-in for renters and operators.

For many tenants, the requirement for a guarantor can become a major barrier to securing a home, particularly for international renters, graduates, relocators and anyone without access to a UK-based guarantor. flatfair says the new product is designed to remove friction at the point of application, while providing operators with a consistent, resident-friendly onboarding experience at scale.

Guarantor requirements are already common in the market. Separate survey reporting suggests around one in five renters have been required to provide a guarantor, while official figures indicate 21% of landlords required a guarantor for their most recent letting.

Approvals within 48 hours

Under Tenant Guarantor, flatfair says approval will be provided within 48 hours once the tenant has submitted all required information, helping speed up decision-making and reduce delays during onboarding.

“Moving home is still too often defined by upfront cost and admin friction,” said Gary Wright, CEO of flatfair.

“By combining Tenant Guarantor with our No Deposit offer, we’re making the move-in journey simpler and more affordable for renters, while giving BTR operators a consistent process that supports a great resident experience at scale.”

flatfair says deposit alternatives are increasingly front-of-mind for tenants and estimates its No Deposit option can reduce upfront move-in costs by more than 70% – with a clear one-off fee, no hidden charges, and no renewal payments. The company adds that “deposit alternative” remains consistently among tenants’ top search criteria.

The announcement comes as the sector prepares for the implementation of the new Renters’ Rights Act. Phase 1 of reforms will begin on May 1 2026, including the abolition of Section 21 and a shift away from fixed-term assured shorthold tenancies to open-ended periodic tenancies.

Wright added: “As the market adapts, onboarding processes that are both resident-friendly and operationally robust are likely to become increasingly important, helping operators manage risk and maintain consistent standards while ensuring renters are not locked out by administrative barriers.”
