What Areas Does Wessex Water Cover?

Wessex Water is the regulated water and sewerage company for most of South West England, operating across Bristol, Bath, large parts of Dorset, Wiltshire, Somerset and areas in Gloucestershire and Hampshire. The company is headquartered at Claverton Down just outside Bath and employs more than 2,000 people. Wessex Water is owned by YTL Corporation, a Malaysian utility group that has held the business since 2002.

Because the supply area overlaps with other companies in some postcodes, it is always worth confirming your supplier before contacting Wessex Water. If your address is on the boundary with Bristol Water, South West Water or Bournemouth Water, a quick postcode check via the Water UK supplier lookup will tell you exactly which company to call for clean water and for wastewater - in much of Bristol these are in fact two different companies.

Are Wessex Water and Bristol Water the Same?

No - Wessex Water and Bristol Water are separate companies with different owners and different responsibilities. Bristol Water only supplies clean drinking water to homes in the Bristol area, while Wessex Water handles wastewater and sewerage for those same properties. Customers in Bristol therefore receive one combined bill issued by Bristol Wessex Billing Services Limited (BWBSL), a joint venture between the two companies.

Wessex Water Contact

Wessex Water runs separate phone lines for billing, operational issues, payments and sewage flooding so that urgent supply problems are never stuck behind routine account queries. Picking the right number first time avoids long hold times - the billing line in particular gets busy around quarterly bill runs and on Monday mornings.

All of the numbers below are UK landline rate. If you have no water, a burst main or sewage flooding, always use the 24/7 line on 0345 600 4600 rather than the daytime billing number.

Social Media

Wessex Water runs an active Twitter/X account (@wessexwater) monitored weekdays from 7:30am to 10pm, which is useful for quick service updates, incident alerts and supply status in your area. For genuine emergencies, however, always call the 24-hour line rather than wait for a social media response.

Wessex Water Pay Now

Wessex Water bills can be paid through several channels so customers can pick whichever suits their budgeting habits. Direct Debit is usually the cheapest and most convenient option, spreading the annual bill across monthly or half-yearly instalments and avoiding the risk of missed payments. Customers who prefer to settle bills manually can pay by card, in cash or by post.

Always quote your customer reference number when paying outside Direct Debit, otherwise the payment may not be credited to the right account and could trigger unnecessary reminder letters.

Payment Methods

  1. Direct Debit (monthly or half-yearly)
  2. Online payment with debit or credit card
  3. Automated phone payment on 0345 600 1019 (24/7)
  4. Internet or mobile banking transfer
  5. Cash at your bank, Post Office or Payzone outlet
  6. Cheque by post

Postal Payment Address

Cheques should be made payable to BWBSL (Bristol Wessex Billing Services Limited) and sent with your account number written on the back to:

Is Wessex Water Expensive?

Wessex Water has historically been one of the most expensive water suppliers in England and Wales, typically sitting just behind Welsh Water (Dŵr Cymru) in annual household bill league tables. This reflects the nature of its supply area - largely rural, with a long coastline, a spread-out customer base and a lot of pipework per customer served.

Moving water around sparsely populated rural counties simply costs more per household than serving a dense urban network, and Wessex Water also has significant wastewater infrastructure to maintain across Somerset, Dorset and Wiltshire. Unlike energy, water customers cannot switch supplier - your supply area is fixed - so the main lever for reducing bills is a water meter and careful consumption, not a switch.

If you think a meter would lower your bill (typically if you have fewer occupants than bedrooms), you can request a free meter installation and trial the metered tariff for up to 24 months before deciding whether to stay on it.

Wessex Water Meter Reading

Wessex Water reads household meters roughly once every six months, so the bill you receive between visits is based on an estimate unless you submit your own reading. Sending an up-to-date reading online is the single easiest way to make sure you only pay for the water you have actually used and to avoid a large catch-up bill once the next manual reading is taken.

Most outdoor meters sit in a small covered chamber near the boundary of the property, often under a blue or black plastic cover in the pavement or front garden. Indoor meters are typically under the kitchen sink or in a downstairs utility cupboard. Before reading, always check that the serial number on the meter matches the one printed on your Wessex Water bill so you know you are looking at your own supply.

How to Read Your Meter

  1. Confirm your home is metered - check a recent bill for a meter serial number.
  2. Locate the meter: outdoor chamber near the property boundary, or indoor under the kitchen sink.
  3. Lift the cover (a flathead screwdriver is sometimes needed for outdoor chambers).
  4. Match the serial number on the meter to the one on your bill.
  5. Record only the black digits - these measure cubic metres and are what Wessex Water bills you on. Ignore the red figures, which show fractions of a cubic metre.
  6. Submit the reading through your online account or by phone on 0345 600 3600.

Wessex Water Moving House

The Wessex Water moving home process depends on whether you are relocating within the supply area, leaving it, or arriving from another water company. In all three cases the account can be handled online, and you should report the move a few days before it happens so the final bill is accurate and the incoming occupant is not billed for water you used.

Customers moving within the Wessex Water region can keep the same account and simply update the supply address; those leaving the area will have their account closed once a final meter reading is received; and new customers arriving from another region are set up from scratch after confirming the address sits inside the Wessex Water boundary.

Online Moving Home Steps

  1. Log in with your current account details (or register as a new customer if arriving).
  2. Enter your moving-out date and a final meter reading for the old property.
  3. Enter your moving-in date and the first meter reading at the new property.
  4. Update your payment details and Direct Debit instruction if required.
  5. Review and accept the terms to close or transfer your account.

If you prefer to handle the move over the phone, or if the online form does not cover your situation (for example a death in the household or a split tenancy), call the billing team on 0345 600 3600.

Wessex Water How Hard Is My Water?

Water hardness across the Wessex Water region varies widely because it depends on the calcium and magnesium content of the rock the water passes through before reaching your tap. Customers in chalk and limestone areas of Wiltshire and Dorset typically receive very hard water, while parts of Somerset and the Mendips can be noticeably softer.

Hard water is perfectly safe to drink but leaves limescale in kettles, boilers and shower heads, shortening appliance life and reducing washing-machine efficiency. To check the exact hardness at your property, enter your postcode on the Wessex Water website - the hardness report will tell you where your supply falls on the soft-to-very-hard scale and is useful information when buying appliances or water softeners.
