Looking for the best lawn mower in the UK? Our 2026 buying guide explains how to choose a lawn mower, compares petrol vs cordless, breaks down garden size recommendations, explains cutting width and ride-on options, and helps you find the perfect mower just in time for that crucial first mow of the season.
How to Choose the Right Lawn Mower
Have you ever asked yourself “What lawn mower do I need for my garden?”, and with so many Yard Force Lawn Mowers to choose from, it can be difficult.
Choosing the right lawn mower can completely transform how you maintain your lawn. Whether you have a compact city garden, a large family lawn, or over an acre of land, selecting the correct mower ensures:
-
Better cutting performance
-
Reduced physical effort
-
Faster mowing time
-
Long-term reliability
In this complete UK lawn mower buying guide, we’ll help you decide based on five key factors:
-
Garden size
-
Terrain
-
Power source
-
Storage space
-
Effort level
1. Garden Size
The size of your lawn determines:
-
The battery runtime needed
-
Whether self-propelled drive is beneficial
-
Whether a ride-on mower becomes practical
Matching cutting width to lawn size is the single most important decision.
2. Terrain
Is your garden flat, sloped or uneven? Uneven lawns benefit from:
- Larger rear wheels
- Self-propelled drive systems
- Petrol engines for added torque
For sloped gardens, self-propelled models significantly reduce strain.
3. Power Source
You’re spoilt for choice when it comes to power sources for lawnmowers, choose between:
-
Petrol - Gives you high power, ideal for large gardens.
-
Cordless Battery - Low noise and low maintenance.
-
Electric - Suitable for smaller spaces with access to mains power.
4. Storage Space
Compact mowers with foldable handles or vertical storage capability are ideal for smaller sheds and garages. If space is limited, avoid large deck petrol mowers unless necessary
5. Effort Level
Self-propelled mowers drive the wheels automatically, meaning you simply guide the mower instead of pushing it. For lawns above 400–500m², this feature dramatically reduces fatigue.
Compact cordless lawn mowers with 32–34cm cutting widths are ideal for small UK gardens under 300m².
What Size Garden Do You Have?
Small Gardens Under 300m²
Small urban gardens require manoeuvrability, lightweight design and easy storage.If your lawn is under 300m² (roughly the size of a small terraced garden or double tennis court), a compact mower with a 32–34cm cutting width is ideal.
Why?
-
A smaller deck means it’s easier to turn is tight spaces
-
Their lightweight design reduces user fatigue
-
They’re easier to store in sheds or garages
-
Lower battery capacity is required to operate
A compact cordless lawn mower is often the best solution for small UK gardens. They are quiet, low maintenance and eliminate the need for petrol storage.
The Yard Force compact 20V 33cm mower or the EasyMow260B would be ideal for:
-
Townhouses
-
Courtyard gardens
-
First-time buyers
-
Low-maintenance households
Medium Gardens 300–800m²
This is the most common UK garden size.For lawns in this range, step up to a 37–41cm cutting width lawn mower.
Benefits:
-
Larger cutting deck reduces mowing time
-
Bigger grass collection box means fewer emptying stops
-
Self-propelled options become worthwhile
-
Higher battery capacity improves runtime
For medium sized gardens around 500-600m² a 40V cordless lawnmower is usually more than powerful enough for regular maintenance. However, if your lawn is thick, slightly uneven or you mow less frequently, a small petrol self-propelled mower may be more suitable.
Yard Force 40V Cordless Lawnmowers with a large cutting deck are ideal for:
-
Semi-detached homes
-
Family gardens
-
Lawns with gentle slopes
Large Gardens 800–1500m²
Large gardens require greater efficiency and cutting power.
Look for mowers with:
-
41–46cm+ cutting width
-
Self-propelled drive system
-
Petrol engine or high-capacity LFP battery
-
Large grass collection capacity
At this size, a small compact mower becomes impractical. A wider deck dramatically reduces mowing time and physical effort.
Petrol lawn mowers remain popular for large gardens because of their unlimited runtime and strong torque. However, modern high-voltage cordless models are increasingly capable of handling larger lawns when maintained regularly.
Yard Force large cutting width mowers are ideal for:
-
Detached homes
-
Corner plots
-
Large rear gardens
-
Heavier grass growth
Ride-on lawn mowers like the ProRider E559 make maintaining large gardens and estates significantly faster.
Extra Large Gardens 1 Acre+
You’ve really got your work cut out for you here, a walk-behind mower in any capacity will quickly become inefficient. At this size, a ride-on mower becomes a smart investment for your perfect lawn.
Why upgrade?
-
Dramatically reduced mowing time
-
Comfort seating
-
Wide cutting deck (typically 106cm / 42”)
-
Adjustable cutting positions
-
Better traction across open spaces
Modern LFP ride-on models also eliminate the need for petrol storage whilst offering quiet operation and lower maintenance compared to traditional petrol powered models. Yard Force’s ProRider E559 Ride-On Mower is ideal for:
-
Rural properties
-
Large country gardens
-
Estates
-
Open, uninterrupted lawns
If your mowing sessions are lasting over 60–90 minutes with a walk-behind mower, it’s time to consider upgrading.

If you’re still unsure of your lawn’s size:
-
Measure the length × width in metres
-
Multiply to get square metres
-
Exclude patios, sheds and flower beds
Example:
20m × 25m = 500m²
That would place your garden in the medium garden category.
Petrol vs. Cordless Lawn Mowers - Which is Better?
This is one of the most common questions UK homeowners ask.
Cordless Lawnmowers
Best for:
-
Small to medium gardens
-
Weekly mowing schedules
-
Low maintenance users
Advantages:
-
Quiet operation
-
No fuel storage
-
Minimal servicing
-
Easy starting
Modern lithium-ion batteries deliver strong and consistent performance suitable for most domestic lawns.
Petrol Lawnmowers
Best for:
-
Larger gardens
-
Thicker grass
-
Longer mowing sessions
Advantages:
-
High torque
-
Unlimited runtime (with fuel)
-
Strong performance in damp conditions
Petrol remains the traditional choice for larger, more demanding lawns.
Self-Propelled vs. Push Mowers
A push mower relies entirely on user effort. Self-propelled mowers drive the wheels automatically, meaning you only guide the mower rather than push it.
They are worth it if:
-
Your lawn is over 400m²
-
You have slopes
-
You prefer reduced effort
For larger gardens, this feature significantly improves comfort.
Understanding Cutting Widths
Cutting width determines how much grass is cut in a single pass.
General UK guide:
-
32–34cm → Small lawns
-
37–41cm → Medium lawns
-
46cm+ → Large lawns
-
96cm (42”) → Ride-on
Wider decks reduce mowing time but may require more storage space.
Choosing the correct cutting width improves efficiency and long-term satisfaction.
Cutting Height Explained
Most mowers offer 5–7 cutting height positions.
Typical UK recommendations:
-
Spring: 25–35mm
-
Summer: 35–50mm
-
Autumn: 40–50mm
Avoid cutting more than one-third of the grass blade at once to maintain lawn health.
Cordless Lawnmower Batteries Explained
Battery specifications can seem confusing, especially when it comes to cordless lawn mowers. Here’s what matters:
Voltage (V)
Indicates power potential.
Amp Hours (Ah)
Indicates runtime capacity. Higher Ah means longer mowing time before recharge. Modern lithium batteries provide:
-
Consistent power output
-
Longer lifespan
-
Reduced weight
Lawn Mower Maintenance & Running Costs
Cordless
-
Minimal servicing
-
Low running cost
-
Occasional blade sharpening
-
Battery replacement over long term
Petrol
-
Annual servicing
-
Spark plug replacement
-
Oil checks
-
Fuel cost
Both types benefit from seasonal blade sharpening for optimal performance.
