The Best Overlockers for Every Budget

Professional seam finishes that rival shop-bought clothing are within reach of every home sewer. As the UK's leading sewing machine specialists with over 20 years of experience, we've tested dozens of overlocker models to find the machines that truly deliver. The right overlocker machine takes your sewing from amateur to accomplished, creating durable seams that stretch with knits, prevent fraying on wovens, and add that polished finish every home sewer dreams of achieving.

Our expert team has personally worked with every machine in this article at our Cornwall showroom. We've put them through rigorous testing on everything from delicate silks to heavy denims, checking stitch quality, threading ease and long-term reliability. Below you'll find the best overlockers for every budget and skill level from BERNINA, Janome, Brother, bernette and baby lock. Still deciding which type you need? Read our guide on how to choose an overlocker.

Quick note for international readers: What we call overlockers in the UK are known as sergers in the US – they're the same fantastic machines that cut, sew, and finish seams in one pass.

An overlocker, also called a serger, trims, sews and finishes a fabric edge in one pass, using 2 to 5 threads to create strong, stretchy seams that won't fray. For a fuller explanation of what an overlocker is and the types available, see our overlocker buyers guide.

Frequently Asked Questions About Overlockers

What's the difference between an overlocker and a regular sewing machine?

Regular sewing machines use two threads for straight stitches, while overlockers use 2-5 threads to simultaneously cut, sew, and finish fabric edges with professional seam finishes.

Which overlocker is best for beginners in the UK?

The Janome 9300DX Overlocker offers the best combination of simplicity, colour-coded threading and value for first-time users.

What Is the Easiest Overlocker to Use?

Air threading overlockers are the easiest to set up because they thread the loopers for you. The baby lock Enspire threads its loopers with a burst of air, and the BERNINA L850 uses a one-step air threader. If you'd prefer a manual machine, look for colour-coded threading and a lower looper threader, like the Brother 2104D.

What Is the Best Overlocker for Home Use?

For most home sewers, the BERNINA L460 is our top pick, with precise speed control, a knee lift and an included extension table. If you're new to overlocking, the Janome 9300DX offers simple colour-coded threading, and the Brother 2104D is a compact, budget-friendly choice.

Is air threading worth the extra cost?

Air threading reduces setup time, making it worthwhile for frequent users who switch between projects regularly. We recommend investing in an overlocker with air threading for sewers who change threads frequently, have poor dexterity such as arthritis, sight and vision issues and occasionally beginners who can afford the extra cost and feel daunted by threading the loopers. Air threading reduces the occurrence of twisted or knotted threads, which can be frustrating. However, if you only intend to use your overlocker occasionally, the time saved with air threading may not justify the higher price. 

Can overlockers handle thick fabrics like denim?

A quality overlocker machine like the Bernina L850 and baby lock Acclaim handles multiple denim layers easily with strong motors and adjustable presser foot pressure. We recommend using the correct needle and quality thread for the best performance. 

What thread should I use in an overlocker?

Use cone threads designed for high-speed sewing rather than regular spools, as they feed smoothly and prevent tension issues. We recommend  Madeira threads - they are designed for smooth running on all types of machines, even at high speeds, minimising looping and ensuring a high-quality finish every time. Their threads offer exceptional quality, durability and vibrant colours. Madeira threads are also known for their high strength and ability to withstand frequent washing. 

Do I need both an overlocker and a coverstitch machine?

Combination machines like the Bernette B48 offer both functions in one unit, though dedicated machines will perform each function better for professional use.
