Frequently asked questions

Who supplies the water in Chesham?

Affinity Water supplies Chesham. You can reach them on 0345 357 2407. In parts of Chesham 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 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 Chesham?

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

Chesham'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 Chesham.
