TSB Launches Energy Efficient Mortgage Range with £250 Cashback: What UK Homebuyers Need to Know

TSB’s New Energy Efficient Mortgage Products

TSB has announced a significant addition to its residential mortgage offering for UK homebuyers. From 9 September 2025, TSB is launching its Energy Efficient Product range, providing an appealing £250 cashback for borrowers purchasing properties with an Energy Performance Certificate (EPC) rating of A or B.

This initiative is designed to encourage environmentally conscious home purchases, rewarding buyers who prioritise energy efficiency with an extra financial incentive.

Overview of TSB’s Energy Efficient Range

TSB’s new mortgage range is targeted exclusively at residential purchase applicants—including those buying through Shared Ownership or Shared Equity schemes. The headline benefit is a straightforward £250 cashback, available in addition to any existing product cashback offered on other eligible TSB mortgages.

• £250 cashback for properties with EPC rating A or B
• Applies to residential purchase applications only, including Shared Ownership and Shared Equity
• New builds with a predicted EPC of A or B also qualify
• The cashback is on top of other existing TSB product cashback offers, such as those on high loan-to-value (LTV) ranges over 85%
• Product rates remain unchanged compared to equivalent standard residential purchase products

This means you get the same mortgage rates as before, with added financial value for choosing a greener property.

Eligibility and Who Can Benefit

The new TSB Energy Efficient range is designed for:

• Homebuyers purchasing properties with an EPC of A or B (including those purchasing off-plan new builds with predicted EPCs in these bands)
• Applicants using Shared Ownership or Shared Equity options
• Those seeking to maximise value from combined cashback offers (the £250 is in addition to other eligible cashback—check TSB’s product guide for full details)

Remortgages and buy-to-let applications are not included—this offer specifically supports new owner-occupier property purchases with strong environmental credentials.

TSB Mortgage Rates and Product Features

TSB’s Energy Efficient mortgage products mirror their standard residential purchase mortgages. This means:

• All interest rates, lending criteria, and standard features remain unchanged
• You can combine the energy efficiency cashback with any existing promotional cashback deals on qualifying products
