3 Best Electric Chainsaws for Cutting Trees (UK 2026)

Choosing an electric chainsaw for cutting trees comes down to more than just motor power. The right model needs enough cutting capacity for the type of wood you are dealing with, while still being manageable when working in the garden or on your property.

Bar Length

The bar determines the size of cut the chainsaw can handle in a single pass. For smaller branches and occasional cutting, a shorter bar can be easier to control. If you regularly cut thicker branches, logs or small trees, look for a longer bar that gives you more cutting capacity.

As a general guide:

• 30–35cm (12–14 inches): Suitable for pruning, branches and smaller timber
• 35–40cm (14–16 inches): A useful size for general garden cutting and medium branches
• 40cm or more (16 inches+): Better suited to larger branches and thicker logs

Do not choose a longer bar simply because it looks more capable. A larger bar can add weight and make the saw less comfortable to handle.

Motor Power

Electric chainsaws are available with different motor outputs, and more power can be useful when cutting tougher or thicker wood. For occasional garden work, a modestly powered model may be sufficient. If you are cutting larger branches or dealing with hardwood, look for a model with enough power to maintain the chain speed under load.

For cordless chainsaws, pay attention to the battery voltage as well as the motor performance. Higher voltage models are generally aimed at more demanding cutting, although battery capacity and the saw’s design also affect how long it can work between charges.

Chain Speed

Chain speed affects how quickly the saw moves through wood. A faster chain can make cutting feel more efficient, particularly when working through thicker timber, but it does not remove the need to use the correct technique.

Weight and Handling

A chainsaw that feels manageable in your hands is easier to use accurately. Weight becomes particularly important when cutting several branches or working for longer periods. Check the weight of the saw with the battery fitted if it is cordless. A model that appears lightweight without its battery can feel noticeably heavier once the battery pack is attached.

Safety Features

Tree cutting carries more risk than ordinary garden pruning, so safety features should not be treated as optional extras.

Useful features can include:

• Chain brake for stopping the chain quickly
• Hand guard to protect the operator’s hand
• Trigger lock or safety switch to help prevent accidental starting
• Automatic chain lubrication
• Chain catcher to help contain a broken or derailed chain
• Low-kickback chain or guide bar design

What Size Electric Chainsaw Do You Need?

For general garden work, a chainsaw with a 30–40cm bar can cover a wide range of pruning and cutting jobs. Larger timber may require a longer bar and a more powerful saw.

The important thing is to match the chainsaw to the diameter of the wood you actually intend to cut rather than buying the largest model available.

Is a 40cm bar long enough for cutting trees?

A 40cm bar can be useful for larger branches and smaller trees, but whether it is suitable depends on the tree and the diameter of the wood. The manufacturer’s stated cutting capacity is a better guide than bar length alone.

Do electric chainsaws need oil?

Yes. The chain needs suitable chainsaw oil for lubrication. Models with automatic oiling systems feed oil to the chain while the saw is running, but the oil reservoir still needs to be checked and refilled.

How often should a chainsaw chain be sharpened?

There is no fixed interval because it depends on how often you use the saw and the material being cut. If the saw starts producing fine dust instead of clean chips, cuts slowly or requires more pressure than usual, the chain may need sharpening.

What safety equipment should I wear with an electric chainsaw?

At a minimum, use suitable eye and hearing protection and sturdy footwear. For chainsaw work, purpose-made protective trousers or chaps, gloves and a suitable protective helmet can provide additional protection. Follow the manufacturer’s safety guidance and use equipment appropriate for the job.
