Seasonality here is extreme

Few categories move with the calendar as hard as garden machinery. Prices climb from early spring, hold through summer, and fall sharply in autumn as retailers clear stock they do not want to store over winter.

The same mower can differ by a large margin between April and October. If the grass can wait, waiting is the single biggest saving available.

Cordless mowers hide the battery cost

As with power tools, cordless mowers are sold both as bare units and with batteries, at prices that are not comparable. Mower batteries are large and expensive, so the gap is bigger here than on a drill.

If the mower shares a platform with tools you own, the bare unit is excellent value. If not, budget for the battery as part of the purchase.

What actually drives the price

  • Power source. Corded electric, cordless, or petrol, in ascending order of price and capability.
  • Cutting width, which decides how long the lawn takes and should be matched to its size rather than maximised.
  • Battery included or not, and its capacity.
  • Self-propelled versus push, a large price difference and the thing most worth having on any slope.

Before you buy

  1. Match the cutting width to the lawn, not to the budget.
  2. Establish whether the battery is included.
  3. Decide corded, cordless or petrol based on the lawn size and the distance to a socket.
  4. Compare in autumn if you possibly can.
  5. Check B&Q, Wickes and Argos as well as the general retailers.

Common questions

When is the cheapest time to buy a lawn mower?

Autumn, when retailers clear stock they do not want to store over winter. Prices climb from early spring and hold through summer, so buying in season means buying at the top.

Is a cordless mower worth it?

For small and medium lawns, usually — no cable and far less maintenance than petrol. Check whether the battery is included, because mower batteries are large and expensive.

How wide should the cutting deck be?

Matched to the lawn. A wider deck cuts faster and is heavier and dearer, and on a small lawn the extra width buys nothing.

Check before you buy, not after
