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

Report it to the supplier for your postcode — Thames Water (0800 316 9800), Affinity Water (0345 357 2407) or Essex & Suffolk Water (0800 526 337). Leaks in the road or pavement are on the public network, and reporting one 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 your supplier: Thames Water (0800 316 9800), Affinity Water (0345 357 2407) or Essex & Suffolk Water (0800 526 337). 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.
