Cost of water in Brentwood

Water rates in Brentwood depend on whether your home has a water meter or not. You can easily find out whether your Brentwood water rates are metered or unmetered rates by checking your water bill or by speaking to the supplier. Homes with metered Brentwood water rates will have a meter number listed on their water bills.
Metered Customers in Brentwood
Customers who have a water meter installed at their Brentwood property will pay an annual charge that is fixed, plus an extra charge for each cubic meter (m3) consumed. The fixed charge is to cover the essential running costs of Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water. While the variable charges cover the usage at your Brentwood home.
Unmetered Customers in Brentwood
Customers who don't have a meter at their Brentwood home pay an annual charge for their water usage. This charge is fixed, meaning you'll pay the same regardless of the amount of water you use at your Brentwood home.
As an unmetered customer, the rate you pay for water in Brentwood is based on the rateable value of your home. The rateable value of your Brentwood water prices were determined by the local council in the 90s and is likely that they have not changed since then.
Should I get a water meter installed?
It really depends on how much water you consume annually. If you are single, or have a small family, installing a water meter at your Brentwood could be cheaper.
Customers with large households are unlikely to see any savings by having a meter installed.
How much is the average water bill in Brentwood?
The average water bill Brentwood residents are being charged can differ between suppliers in your area. The table below shows the average water bill by supplier:
Supplier | Average Water Bill Per Month | Average Water Bill Annually |

Brentwood Water Frequently Asked Questions
Below we have answered the most commonly asked questions that customers in Brentwood have about their water supply.
Frequently Asked Questions About Water in Brentwood
Is the tap water in Brentwood safe to drink?
Yes! You can drink the tap water in Brentwood. You can rest assured that Brentwood water meets high standards making it safe to drink. The UK Drinking Water Inspectorate has rated Brentwood water quality 99.94% in overall mean zonal compliance, which means your water is safe to drink. It is not required to boil or filter Brentwood water to make it drinkable.
Where does the water in Brentwood come from?
There are three main sources of water that supply Brentwood:
- Surface sources - 93%
- Groundwater sources - 6%
- Mixed sources - 1%
What's the water hardness rating in Brentwood
While rainwater itself is relatively soft, water hardness can change through the water cycle. As rainwater filters through rocks, it picks up minerals, such as magnesium and calcium. The more minerals the water picks up, the harder is your water considered.
The water hardness rating in Brentwood is more than 201ppm, this means the water in Brentwood is rated as hard water.
What does this mean?
The water supply to your home in Brentwood contains slightly elevated levels of minerals that cause hard water. hard water will not clean your clothes, dishes, or your body efficiently, and your appliances will be less efficient which is not good news for your utility bills. You might also notice more limescale build-up in your appliances and it may affect the taste of your tap water.
Selectra recommends
We recommend adding a softening agent to the water in Brentwood.
- Baths, sinks, and toilets - Use an acidic sanitiser regularly (available in local shops) to clean susceptible surfaces in order to clear limescale deposits.
- Kettles - Don't completely fill your kettle with water. You can clean your kettle by half-filling and diluting two tablespoons of white vinegar, leaving it for four hours in order to loosen scale build-up. Rinse and repeat to remove scale.
- Dishwashers - Use the built-in water softener. Make sure you occasionally top it off with dishwasher salt in the right compartment.
Brentwood No Water
If you have no water in your Brentwood home, you will first need to find out whether the problem is with your home plumbing or if the problem is a widespread issue affecting Brentwood.
If there is no water at your Brentwood home, is it only affecting cold water or hot water? If you still have cold water but no hot water, the problem will be with the plumbing at your home and not a problem affecting Brentwood.
If you don't have any cold water, not even a trickle, contact Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water for help. If this is the case, you can try these tips:
- Check for updates on the "In Your Area" sections of the Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water website for any explanations as to why you have no water.
- Have a look at the Twitter account for Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water, quite often you will find they have posted an update about the issue.
- Ask your neighbours whether they have the same issue as you.
- Check that your stop tap is open.
Brentwood water leak or flooding
Brentwood water problems can include anything from a burst water main or flooding, to a leak in your Brentwood home. This means it's very important you know what to do and who to contact regarding a water emergency.
If you discover flooding or a water leak outside your Brentwood property, you need to do one of the following as quickly as you can:
- Ring Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water regardless if the issue relates to drinking water or wastewater.
- If you have access to the internet, go to the "report a leak" section of the Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water website and fill out the online form.
Why does the water in Brentwood taste strange?
If you notice a change in taste or smell with your Brentwood water this could be down to one of the following reasons:
- Chlorination is a safe way to make sure the pipe network maintains high levels of hygiene throughout.
- Seasonal changes can impermeate the Brentwood water with an earthy smell or taste.
- Plumbing can also contribute to the taste of your household water, adding rubbery, salty, or metallic hints to Brentwood water.
If you are unsure about your water's appearance, smell, or taste, you can speak to Affinity Water, Anglian Water, Essex & Suffolk Water, or Thames Water on the contact details above.
