How to Choose the Right Lawnmower for Your Garden

Lawn Size

  • Under 100 sq m: hover, corded electric or entry-level cordless
  • 100–400 sq m: cordless with 33–40cm width and 30–45 minutes’ runtime
  • 400–800 sq m: self-propelled cordless or petrol
  • Over 800 sq m: petrol or robot mower

Terrain and Slope

Flat lawns suit almost anything. Slopes and uneven ground favour a hover or a self-propelled rotary, while cylinder mowers need reasonably level ground.

Storage Space

Choose a folding or vertically storable mower if space is tight.

How Often You’ll Mow

Weekly mowing suits most machines. An overgrown lawn needs a rotary with plenty of power.

Key Features to Look For

  • Cutting width: 30–33cm (small), 36–42cm (medium), 44cm+ (large)
  • Grass box capacity: 30–40 litres (compact), 50–60+ litres (larger)
  • Mulching function: returns fine clippings as natural feed
  • Self-propelled vs push: self-propelled is essential for large or sloping gardens
  • Adjustable cutting height: four to five settings (about 20–70mm)
  • Brushless motor (cordless): more efficient, quieter and longer-lasting

How Much Should You Spend?

Budget: under £150. The Greenworks GD24LM33 (around £120–£150) covers basic entry-level cordless needs.

Mid-range: £150–£350. The Bosch AdvancedRotak 36-750 offers good width and clean stripes, typically £250–£350 with battery.

Premium: £350–£650. The EGO LM1702E-SP (around £550–£650 with battery) and Honda IZY HRG416 (around £380–£450).

Premium petrol: £300–£600+. The Mountfield SP53 self-propelled petrol mower (around £280–£350) and Honda models reaching £500–£600.

Lawnmower Care and Maintenance

  • Cordless mowers: clean the deck after use, sharpen the blade annually and store the battery at around 50% charge.
  • Petrol mowers: change oil seasonally, replace the air filter and spark plug, drain petrol over winter and sharpen the blade annually. With this routine a Honda or Mountfield petrol mower should give you fifteen to twenty years.
  • Robot mowers: check wire connections, replace blade cartridges regularly and clean the charging contacts.
  • Cylinder mowers: back-lap the blades annually and check bottom-blade alignment.

Frequently Asked Questions

What is the best type for small UK gardens?

For a small garden (under 100 sq m), a compact cordless mower or a corded hover mower is usually the most practical.

Is cordless as good as petrol?

For most UK gardens, yes. A good cordless mower from EGO or Bosch will cut just as well. Petrol still wins on unlimited runtime, tough conditions and long-term durability.

How often should I mow?

Once a week during the growing season (April to October), and twice weekly in spring and early summer.

Should I mulch or collect?

Both work. Collecting gives a neater finish; mulching returns nutrients to the lawn and saves emptying the box.

What cutting height should I use?

Around 25–40mm suits most UK lawns. Go lower for formal lawns and raise to 50–60mm in drought.

Can I use a cordless mower on wet grass?

Most handle lightly damp grass, but avoid soaking wet lawns as the grass tears and clogs the deck.

How long does a mower battery last?

A quality lithium-ion battery should last 500–1,000 charge cycles, which is five to ten years of seasonal use.

Final Verdict

For most UK gardeners with a small to medium lawn, a cordless mower in the £200–£400 range, such as the Bosch AdvancedRotak or a mid-range EGO model, offers the best balance. Step up to petrol for large or unruly lawns, and consider a robot for the maintenance-averse. Buy from a reputable brand, keep the blade sharp and give it a basic service each spring.
