According to the data, product choice overall rose to 1,743 savings deals (including Isas), by the end of March.
The Moneyfacts data also showed that all variable rates (easy access, notice and Isa equivalents) rose for the 13th consecutive month, thanks to competition and back-to-back Bank of England base rate rises.
Springall added: "It is imperative that consumers take time to check any variable rates they have against the top rates, especially as the average easy access rate is 1.60 per cent higher than a year ago.
"There will be accounts out there which have not received the full benefits of base rate rises and it is down to savers to compare and switch.
"Growing choice in the market means it is more important than ever for savers to consider both unfamiliar and household names, as there are now more overall savings deals on the market since October 2022."
