Water and sewerage

The single water and sewerage provider for the whole of Scotland, and publicly owned. Household water and sewerage charges are collected with council tax rather than billed separately, so there is usually no water account to open when you move in.

A few useful answers

Common questions

Who supplies water in the KA postcode area?

Scottish Water supplies water in the KA postcode area. The supplier is decided by where the property is, not by who lived there before you.

Can I switch water supplier in KA?

No. Household water supply is not a competitive market anywhere in the UK — there is one supplier for each address and no tariff to compare. What you can change is how you are charged, by asking for a meter.

Does one company handle both the water and the sewerage in KA?

Yes. Scottish Water does both, so one bill normally covers the water supply and the waste water together.

Do I need to open a water account when I move in?

Usually not. Scottish Water does not bill households separately for water, so there is normally no account to open when you move in.

Where to confirm this

We hold the supplier at postcode-area level, which is coarse enough to be wrong at a boundary. These are the industry's own sources, and they settle it for a specific address.
