What to do if you have
a blockage
If you find that your system is
affected and water is not draining away properly, there may either
be a blockage on your private system or the public sewer may be
blocked.
- Check that it is not just your drain that is blocked. If
your neighbours are not affected, call an emergency plumber to
clear the obstruction.
- To report a blocked sewer, you need to contact Thames Water on
0845 9 200 800.
- If you are unsure you can contact Housing & Public
Protection on 020 8430 2000 (Monday to Friday 9 am to 5 pm).
- Council and Housing Association tenants should contact their
local housing office.
