Frequently asked questions

Who supplies the water in Stevenage?

Affinity Water supplies Stevenage. You can reach them on 0345 357 2407.

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

Report it to Affinity Water on 0345 357 2407. 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 2407. 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 Stevenage?

Your water comes from Affinity Water, but wastewater and sewerage in Stevenage is handled by Thames Water / Anglian 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 Stevenage?

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