Why choose a AIB (NI) Self-Build Mortgage?


Free Self-Build Specialist

‘Interest Only’ Option

Our ‘interest only’ option is available for your construction period up to 18 months from the initial drawdown.


No Application or Booking Fees

With a AIB (NI) self-build mortgage, you won’t have an application fee or booking fee.


Stage Drawdowns Available

You can draw down your mortgage in up to 4 stages, depending on the size and complexity of the build.

Meet a Mortgage Adviser

Talk to a AIB (NI) Mortgage Adviser to discuss the self-build process. They will answer any questions you may have and guide you through the process.


Planning Permission

You will need full planning permission in order to get approval for a self-build mortgage.

Consult your Local Authority for more information on planning regulations in your area before you proceed with your mortgage application.


Plan Your Finances

Plan your finances before you start your build and take into account any variations that may arise. Think about extra costs such as solicitor fees, valuation fees and Stamp Duty Land Tax, and the cost of furnishing and decorating your new home. Our independent Self-Build Specialist will verify projected costs and help minimise over-spending during the build.


Arrange Insurance Cover

You need to have self-build insurances (property under construction insurance and public and employee insurance) in place before you can draw down your mortgage.


Stage Payments

Once approved, self-builders can draw down their mortgage in up to 4 stages within a maximum of 18 months – allowing you to borrow only what you need across the period of the build.

Representative example


  • Loan value: £147,357
  • Loan term: 29 years
  • Loan Type: Self Build
  • Initial monthly repayments: £706.02
  • Interest rate: currently 3.8%
  • APRC (annual percentage rate of charge): 4.0%
  • Number of monthly instalments: 348
  • The following fees are included in the calculation for this example:
    • Funds transfer fee, £30;
    • Mortgage exit fee, £55;

If the rates do not vary during the term of the mortgage, the total cost of credit (the total amount repayable less the amount of the mortgage) would be £98,622.96. This means that the borrower would have to pay a total amount of £245,979.96. Home insurance is required.
