What we tested

We tested ladders suitable for most home maintenance and DIY projects. The ones we chose had six rungs and were 1.8 metres high in the "A" shape and extended to around 3.2 metres when used as a straight ladder. We bought our combination ladders at major hardware outlets.

When you buy a ladder it's usually rated in kilograms and as "domestic" or "industrial/trade". The combination ladders we tested fell into two categories: a 120kg load rating and a rating that ranged from 135 to 180kgs.

Use the load rating as your guide when buying a ladder rather than whether it's labelled for "domestic" or "trade" use. The 120kg ladders will handle general DIY activities around the home. But if you're using your ladder for heavy-duty DIY, then go for the highest load rating you can afford. They are built to a higher specification.

Our test

For our test we used a laboratory accredited for testing ladders. It put our 11 ladders through their paces against nine parts of the Australian/New Zealand standard that test for safety, strength and rigidity. When you're several metres off the ground cleaning the guttering or painting you want to know your ladder is safe.
