Under the Consumer Rights Act 2015, goods must be fit for purpose. This is one of the three core legal standards that apply whenever you buy goods from a trader.

Alongside being of satisfactory quality and as described, fitness for purpose is a key protection when something you buy does not do what it is supposed to do.

For a broader explanation of faulty goods, see Faulty Goods Explained.

The Basic Rule

Goods must be capable of performing the function that goods of that type are normally supplied for.

In simple terms, the item must do the job it is meant to do.

For example:

  • A kettle must boil water.
  • A waterproof jacket must resist rain.
  • A fridge must keep food cold.
  • A laptop must operate as a working computer.

If the product cannot perform its ordinary purpose, it may breach the Act.

Specific Purpose You Tell the Trader About

The protection goes further if you tell the trader about a particular purpose before buying.

If you:

  • Explain what you need the item for, and
  • Rely on the trader’s advice or recommendation.

Then the goods must be fit for that specific purpose.

For example:

  • You tell a retailer you need paint suitable for a bathroom with high humidity.
  • You explain you need a laptop capable of running advanced design software.
  • You ask for shoes suitable for long-distance trail running.

If the trader recommends a product that does not meet that requirement, you may have a claim.

What If You Chose the Product Yourself?

If you choose a product without asking for advice, the trader is generally only responsible for ensuring it is fit for its normal purpose.

However, it must still:

  • Be of satisfactory quality.
  • Match its description.

When Goods Are Not Fit for Purpose

Examples of goods not being fit for purpose include:

  • A lawnmower that cannot cut grass properly.
  • Outdoor furniture that rusts immediately despite being marketed for garden use.
  • A phone advertised as water-resistant that fails under normal use.

In these cases, the goods may be legally faulty even if they appear undamaged.

When the Trader May Not Be Responsible

The trader may not be liable if:

  • You did not tell them about a special requirement.
  • You ignored clear warnings about suitability.
  • You misused the product.
  • The issue is normal wear and tear.

The law protects you against inherent faults, not damage caused by misuse.

Your Remedies

If goods are not fit for purpose, you can use the same remedies available for other faults.

Within 30 Days

You can usually reject the goods for a full refund.

The 6-Month Rule

If the issue appears within six months of delivery, it is presumed the fault was present at the time of delivery unless the trader proves otherwise.

In Simple Terms

“Fit for purpose” means the product must do what it is supposed to do — and if you told the trader about a specific requirement, it must meet that requirement too.

If it does not, you are entitled to a repair, replacement, or refund under the Consumer Rights Act 2015.
