Update: water supply issues in the GU1, GU2, GU3, GU4 and GU5 areas has been resolved

The majority of customers' supply should have returned by now. However for those who are still without supply, this will be as a result of air pockets. Read advice from Thames Water about no water or low pressure

If you are still experiencing issues with your water supply this morning you can get free bottled water from a Thames Water bottled water station. For water stations opening times and updates, visit Thames Water website.

If you need support from an engineer to get your water supply back to normal, please call Thames Water on 0800 316 9800.
