Why We Like Tandem Bank
We like Tandem for its successful specialist approach and genuine commitment to sustainability. It excels by offering some of the best savings rates on the market (up to 5.25% AER) and providing a clear, useful path to finance sustainable home improvements, all within a straightforward and reliable app. For savers looking to maximise returns on their cash and environmentally-conscious homeowners planning green upgrades, Tandem is an excellent choice to complement a primary current account.
How We Compare Digital Banks
Tandem operates in a completely different space to full-service digital banks like Monzo or Starling. It is not a current account competitor but a focused 'satellite' bank ideal for housing your savings or funding a specific green project. While Monzo offers savings pots within its current account, Tandem provides dedicated savings products with consistently higher rates. For users wanting the best returns on their savings alongside the ability to finance eco-friendly home improvements, Tandem is purpose-built for these specific needs. It works best when paired with a traditional current account for everyday spending.
