Chainsaw Fit Check

Answer three questions and we will match your task to a sensible bar length and power type, plus the PPE you need whatever you buy. Rule-based, not a sales quiz - no specific saw is recommended by name.

Always wear EN381 rated PPE: chain-brake, gloves, leg protection, eye and ear protection, whichever saw you choose.

Size the saw to the wood, not the wish list

The bar length that matters is the one that matches your thickest cut, not the biggest saw on the shelf. Pick a bar roughly 5cm longer than the thickest branch or trunk you expect to cut: a 15cm branch does not need a 45cm petrol bar bought 'just in case'. Power type follows the same logic: corded electric handles light pruning under about 20cm near a socket, cordless battery saws cover most portable UK garden work away from a plug, and petrol earns its weight and noise on regular firewood processing or storm and felling clearance.

Guide reviewed for accuracy: 10 July 2026

The recurring complaint across the owner threads and reviews we research (Arbtalk, UK retailer reviews, Amazon UK) is a saw that is too heavy, too loud or too much machine for the job, not one that is underpowered. Buying bigger 'just in case' is the more common regret. That is why the Fit Check above is deliberately conservative rather than aspirational.

The beginner's guide covers the training and features that matter most before you buy your first saw.

Chainsaw bar length by task: corded electric for cuts under 20cm, cordless battery for 20 to 25cm, petrol for 25cm and over Corded electric up to 20cm, 12 to 14in bar Cordless battery 20 to 25cm, 14 to 16in bar Petrol 25cm+, 16 to 18in bar
Bar length follows the cut, not the other way round: corded electric for cuts under 20cm, cordless battery for 20 to 25cm, petrol for 25cm and over.

Why bestchainsaw.uk

We do not run a test lab and we do not stage saws cutting logs for a camera. Best Chainsaw is research led: recommendations are built from published manufacturer specifications, verified owner and community reviews (Arbtalk, forums, Amazon UK and retailer reviews), UK retail pricing, and HSE/EN381 safety standards, cross-checked so the numbers on this page match the numbers on the box. Where a figure is the maker's claim rather than an independently measured result, we say so.

Rankings weigh bar length and power for the task, safety features, build and value at UK prices. We update picks when models are discontinued or superseded. We earn affiliate commission on some links, but it never decides the order of a list. More on our method.

Frequently asked questions

What size chainsaw do I need?+
Match the bar to your thickest cut, not the biggest saw you can afford. Pick a bar roughly 5cm longer than the thickest branch or trunk you will cut: under 20cm calls for a 12 to 14 inch bar, 20 to 25cm calls for 14 to 16 inches, and over 25cm or regular felling needs 16 to 18 inches. Use the Fit Check tool above for a recommendation based on your own task.
Electric vs cordless vs petrol: which should I get?+
Corded electric is the cheapest and quietest choice for light pruning under about 20cm near a socket, cordless battery is the most portable option for general UK garden work away from a plug, and petrol is worth the extra weight and noise only for regular firewood processing or storm and felling clearance. See the electric, cordless and petrol guides for the detail.
Do I need a licence for a chainsaw in the UK?+
No, not for domestic or personal use in your own garden: there is no licence requirement to buy or own a chainsaw in the UK. The Health and Safety Executive (HSE) only requires a valid certificate of competence when a chainsaw is used at work or in a professional capacity. Training is not a legal requirement for personal use, but we would still recommend it: see our chainsaw safety guide.
What PPE do I need to use a chainsaw safely?+
EN381 rated protective equipment is the minimum: a working chain brake on the saw itself, cut-resistant gloves, leg protection (chainsaw trousers or chaps, Class 1 minimum), and eye and ear protection. Our chainsaw safety guide covers PPE classes and kickback risk in full.
