Bank of England Bank Rate

3.75%

Held on 17 September 2026. The next decision is due on 5 November 2026.

What this means for you

Fixed-rate buy-to-let mortgages are priced mainly on what markets expect Bank Rate to do, so Bank Rate is a guide to direction rather than the rate you'll pay. Overseas borrowers usually pay more than UK residents. Use the analyser's stress test to see what a higher rate does to your deal.

The pound against the Australian dollar

£1 = A$1.8883

Also US$1.3263 and €1.1657. European Central Bank reference rates for 28 September 2026.

What this means for you

Your deposit and your rental income both cross this rate. If the pound is 10% weaker when you buy, your deposit costs 10% less in Australian dollars, but your income is worth 10% less when you bring it home. Banks and transfer providers add a margin to this rate.
