A building society can do anything this law allows it to do, as well as other things that help it do its job, as long as its own rules don't say it can't. The society's rules might limit what it can do, but if they don't, the society has a lot of freedom.

When a building society uses its powers, it can act in different ways. It can act as the main person doing something, or it can act for someone else. It can also act as a lawyer for someone, as a worker, as someone who looks after money for others, or in other ways.

The society can also get other people or companies to use its powers for it. These could be people acting for the society, lawyers, workers, people who look after money, or others.
