What home improvements qualify?

How does it work?

  • Spending the funds: Your client must spend 100% of the Green Additional Borrowing amount on green home improvements and supporting works. Document a full breakdown of the planned use of funds in your advice notes.
  • Interest rate: The 0% interest rate stops when the fixed deal period ends. Any outstanding amount will automatically move to our variable Standard Mortgage Rate (SMR). Or your client can switch to another rate, subject to availability and eligibility.
  • Property limit: There is a limit of one 0% Green Additional Borrowing mortgage per property.
  • Borrowing limit: The maximum borrowing amount is £20,000. If your client requires additional funding for green home improvements, you can also apply for standard additional borrowing. Complete the Green Additional Borrowing case before starting the application. The Green Additional Borrowing means your client's LTV may change, and available products may be different.
  • Application limit: Your client cannot apply for more than one Advanced Borrowing product with us at the same time. If your client wants to apply for Green Additional Borrowing and Additional Borrowing (further advance), they must choose which order to apply. Start the second application after the first completes and they make their first monthly payment.

How could Green Additional Borrowing help your clients?

"We've just moved in and have urgent work to do - what are our options?"

A client has recently moved house and their first Nationwide mortgage payment has cleared. The insulation is poor and the gas boiler has failed, and they need to upgrade to an electric boiler. It will cost up to £8,000 for these upgrades. Unsecured lending is costly and a further advance has higher rates. However, this client could secure a Green Additional Borrowing mortgage at 0% and tackle those upgrades straight away.

"We want to buy and upgrade immediately"

A client is purchasing a new home and knows it needs new windows, insulation, and smart heating, which will cost between £15,000 and £20,000 to complete. For additional borrowing, clients would normally need to wait 180 days before applying. For Green Additional Borrowing, however, there is no need to wait; they only need their first Nationwide mortgage payment to clear.
