Certificates of deposit (CDs) are still a solid way to lock in a guaranteed return, especially when interest rates are climbing. In 2025, banks and building societies are offering a range of rates that can beat many regular savings accounts. This guide walks you through the basics, shows how rates are set, and gives you practical steps to pick the right CD for your goals.
Rates today reflect a mix of the Bank of England base rate, market competition, and the term length you choose. Longer terms usually pay more because the bank can use your money for a longer period. If the base rate goes up, most CD providers will raise their offers within a few weeks. Keep an eye on the Bank of England’s monthly announcements – they’re a good early warning for rate changes.
Another factor is the type of institution. Large high‑street banks may offer slightly lower rates but give you easy access to branches. Smaller building societies and online‑only banks often chase customers with higher rates to grow their deposit base. In 2025, many online providers are topping out at 5% for 12‑month CDs, while some regional building societies are nudging 4.5% for 24‑month terms.
Start by deciding how long you can leave the money untouched. If you need flexibility, a 6‑month or 12‑month CD is safest. For a bigger payoff, look at 18‑ or 24‑month options, but be sure you won’t need the cash early – penalties can eat into your earnings.
Next, compare the annual percentage yield (APY). Some providers quote a nominal rate, which doesn’t factor in compounding. The APY shows the real return you’ll get over a year, assuming you leave the money in for the full term. Websites that aggregate CD rates can save you time, but always double‑check the provider’s page for any hidden fees.
Don’t forget the tax angle. CD interest is taxable as regular income, so a higher rate might not always beat a tax‑free ISA if you’re a higher‑rate taxpayer. You can still use an ISA wrapper for a CD‑like product – look for “fixed‑rate ISAs” that give you a set return with tax advantages.
Finally, read the fine print. Some banks offer “bonus” rates that drop after the first few months, or they might require a minimum deposit that’s higher than you expect. If you’re comfortable with a larger upfront amount, you can often lock in the top tier rates.
To sum up, 2025 brings solid CD options across the UK. Pick a term that matches your cash flow, compare APYs, watch the base‑rate trends, and mind the tax impact. With a bit of research, you can secure a reliable, higher‑earning place for your savings that beats most everyday accounts.
