Power up and tackle those tough garden jobs

Save yourself plenty of hard work in the garden with a chainsaw. These powerful tools can be used for a number of backbreaking chores, such as felling trees and chopping logs for firewood. They can help with domestic garden clearance, especially cutting work that’s too much for a shredder, and in times of emergency, such as cutting back fallen branches after a storm. So if you’ve ploughed on with these tough jobs using an axe or saw, consider hanging them up in favour of a chainsaw as we take you through what options are available.

What to consider before buying a chainsaw

Before buying a chainsaw, it’s important to understand how you’re going to be using it. This can help determine which of the many different types available is best for you.

What are you going to use it for?

Ask yourself what material are you going to be cutting. This affects how much power you’re going to need to efficiently and effectively complete the job. The smaller the job, or the softer the cutting material – the less power is needed. So for example, if you’re cutting hardwood trees in your garden, you’d look for a more powerful chainsaw rather than one being used to chop softwood for a fire.

How far away from a power source will you be using your chainsaw?

You’ll never be too far away from a mains electricity socket if you have a smaller garden, giving you more options than if you’re looking to use your chainsaw in a larger space.

How experienced are you using a chainsaw?

If you’ve never used this type of garden power tool previously, consider using the least powerful one possible to achieve your job. There’s no need to get the most powerful one available if you’re never going to need all that extra oomph. Buying it could just mean you end up shouldering a heavier tool but never benefitting from the extra power. However if you’re more seasoned, choose from the entire range available.

Now having a better sense of your cutting needs, you can determine which type of chainsaw you should opt for.

Choosing your chainsaw power type

Like many garden power tools, there are three core varieties available – petrol, corded or cordless.

corded chainsawcorded chainsawcorded chainsawcorded chainsaw


Corded chainsaws, also known as plug-in or electric chainsaws, share many similarities with cordless models being lightweight, low maintenance and quiet. Yet while they can be more powerful than battery chainsaws, they’re often not as powerful as their petrol counterparts and so are ideal for smaller jobs and less experienced users. Being plugged into a mains electricity socket, they only offer limited movement and users must be aware of the trailing cord at all times for safety. However portability issues can be eased if used close to the power source or with an extended cable lead and RCD protector for safety. A corded chainsaw’s power is measured in Watts (W).

If you don’t have access to an outdoor power source or have a larger garden where an extension cable simply is not practical, then a cordless chainsaw could be perfect for you. Cordless models offer many of the benefits of corded models, being lightweight, easy to use and maintain, but offer the freedom of petrol, making them ideal for a variety of garden sizes. They are also the most environmentally friendly power type as you do not generate any emissions and do not need mains power supply.

With advances in technology, cordless models can now run for much longer and can cut larger areas versus older models. Although we state the runtime you can get from your tool where possible, in real world use there are a number of factors that influence the runtime and more information on this can be found here.

The majority of our cordless products are sold as kits, meaning you will get a battery and charger included. Products sold without these are commonly referred to as baretools. The majority also come with interchangeable batteries. This means a number of different garden power tools are part of the same battery platform and will work using the same battery. Depending on the vendor the same battery will also work on indoor power tools, giving you greater convenience and potentially a bigger pool of spare batteries.

Petrol chainsaws offer the greatest power and so get through jobs quicker than other models. Using a two stroke engine, their higher performance means they’re best suited for bigger cutting jobs, regular use and more experienced users. They’re portable and so are great if working away from a power source, however they’re heavy, noisy and require regular maintenance. There’s also the cost of the necessary further purchases – the petrol itself, engine oil to keep it running smoothly, a petrol can for transportation and perhaps a funnel for easy filling.

A petrol chainsaw’s power is measured by engine size, often referred to as cubic capacity, in cubic centimetres (cc). The larger the engine, the more power is being sent to the cutting mechanism delivering more torque and all round better performance.

Features to look out for

There are a number of further technical specifications and key features that chainsaws offer which are important to consider.

Pole chainsaws

We also stock a range of extendable pole saws to target harder to reach areas such as high branches. Although you may not get the same finish as using a standard chainsaw and a ladder, they are safer to use and the extension pole allows you to reach much higher branches. You can also adjust the angle of the saw to cut where you need it to.

Bar length

Measured in centimetres (cm).

Bar length refers to the length of the cutting bar on the chainsaw which determines the size of cutting area. Essentially, the bigger the bar, the bigger the size of log you can cut in a single pass. Petrol models have longer bars than corded or cordless types, with domestic use chainsaws ranging up to 40cm.

Chain Speed

Measured in metres per second (m/s).

Chain speed dictates how quickly you can cut through the material, the higher the number the speedier the tool’s performance. Corded and cordless types commonly offer around 9m/s, whereas petrol models are often closer to 20m/s.


Measured in kilograms (kg).

The weight of a chainsaw is key as it influences your comfort when using it. Lighter models, such as corded and battery powered, offer greater ease of movement and increased manoeuvrability than heavier petrol ones.

Handle Type

Like weight, type of handle relates to usability and there are a number of different features to look out for. Opt for models with anti-vibration and ergonomic soft-grip handles to minimise discomfort, or wrap-around handles for better accuracy when cutting at odd angles.

Chain Tensioning

Also known as chain adjustment, chain tensioning maintains the necessary tension in the chain to ensure its safe to use. Some models come with a tensioning tool that allows you to tighten the chain and remove any unwanted and dangerous slackness. Look for ones that offer tool-less tensioning – simply twist the dial on the side of the chainsaw and it’s done.

Kickback brake / Anti-kickback function

Kickback describes when the chainsaw tip hits another object and gets thrown up and towards the user. Many models look to minimise the risk of this occurring through an anti-kickback brake or inertia chain brake. If kickback occurs, this safety feature automatically responds forcing the chainsaw to stop.

Looking after your chainsaw

Helping you care for your chainsaw

With good care and maintenance, a chainsaw can last a number of years. To keep yours in good working order, consider picking up:

  • Chain lubrication oil. Many chainsaws are already oiled and feature an automatic oiling mechanism for constant lubrication. But this can need supplementing to stop rust setting in so top up with some oil to keep it moving freely.
  • sharpener to prevent the chain from becoming blunt.
  • Replacement chains in the event of the existing one wearing out.

There is a range of support available should you encounter an issue with your chainsaw at any stage. If you have bought your product within the last 6 months you may be entitled to a refund if brought back to store, however there is a variety of other support available. We stock a wide range of spare parts both instore and online with matching parts across lawnmower blades, trimmer spools and chainsaw chains to name a few, spare batteries for cordless products and a range of oils and fuel enhancer for petrol products. All our vendors also have aftersales contact support available which can help you troubleshoot any issues and provide any advice on how best to look after your product or in some cases send you spare parts or repair your product. These details can be found here.
