Northolt Water Services

Frequently asked questions

Who supplies the water in Northolt?

Affinity Water supplies Northolt. You can reach them on 0345 357 2401. In parts of Northolt the supplier can vary street to street, so check your bill if you are not sure.

I can see water leaking in the road — who do I tell?

Report it to Affinity Water on 0345 357 2401. Leaks in the road or pavement are on the public network, which is theirs to fix — anyone can report one, and it costs nothing.

I have no water — what should I do?

Check with a neighbour first. If they have no water either, the problem is likely on the mains — call Affinity Water on 0345 357 2401. If it is only your property, check your internal stop tap is fully open; if it is, the fault may be on your own supply pipe — the part we repair and replace.

Who handles sewerage and drains in Northolt?

Your water comes from Affinity Water, but wastewater and sewerage in Northolt is handled by Thames Water — a separate company. The drains inside your property boundary are the owner's responsibility — that is the work we do.

Is the water hard or soft in Northolt?

Northolt's water is hard, and the risk of limescale in kettles and boilers is high. A filter or softener can help — see our water filter guide for Northolt.
