A few useful answers

Common questions

Who supplies water in the NW postcode area?

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

Can I switch water supplier in NW?

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 NW?

Yes. Thames 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?

Yes. Tell the supplier the day your tenancy starts and give an opening meter reading if the property has a meter, so you are not billed for what the last tenant used.

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.
