The best single-boiler espresso machine under £600.

The Victoria is where Lelit's LCC control centre really shines. The OLED display shows brew and steam temperatures, shot time, and lets you program pre-infusion duration — features usually reserved for machines at twice the price. The 58mm LELIT58 group head takes standard commercial accessories, the brass boiler provides good thermal stability, and the stainless steel body is compact enough for most kitchens. This is the single-boiler machine that makes the strongest case against upgrading to a dual boiler — for most people making 1-3 drinks at a time, the Victoria's PID and pre-infusion capabilities are more than enough.
The Victoria + Niche Zero is the sweet spot pairing. The Niche's single-dose workflow and zero retention complement the Victoria's shot-to-shot consistency perfectly.
You see espresso as a long-term hobby and want a machine with room to grow. The programmable pre-infusion and precise PID control let you experiment in ways cheaper machines can't match. This setup will keep you engaged for years.
