Can I switch my water supplier to Thames Water or away from it?

No, household water supply in England is a regional monopoly, so you can't switch your residential water supplier the way you switch energy or broadband. Thames Water supplies a fixed area of London and the Thames Valley. Only **non-household (business) customers** can switch their retailer via the Open Water scheme. If you cancel your account without moving, you risk being left without water.

Does Thames Water have a cancellation fee?

There's no cancellation fee for closing a household account when you move, it's a regulated water service, not a contract with an exit penalty. However, **metered customers** who give less than 2 days' notice of a move can be **liable for charges for up to 28 days** after Thames Water discovers they've moved out. Submit a meter reading on your move-out day to avoid extra charges.

What is the email address for Thames Water complaints?

For bill and account complaints, Thames Water directs customers to webchat, phone (**0800 980 8800**), WhatsApp, or post (**Thames Water, PO Box 436, Swindon, SN38 1TU**). Community-reported working email addresses include **customerservices@thameswater.co.uk** and **customer.feedback@thameswater.co.uk**, CC both to build a paper trail, as a single mailbox is often ignored. They aim to respond within 10 working days.

Can I close my Thames Water account online or do I have to call?

Thames Water says you **don't need to call**, if you're leaving their area you can close the account in your online account in a few simple steps, giving a meter reading and forwarding address. In practice, some customers have hit form errors and had emails go unanswered; if the online form fails, call **0800 980 8800** or use their webchat/WhatsApp channels.

What happens if Thames Water ignores my cancellation or complaint?

Follow the formal complaints route first (email plus post to PO Box 436, Swindon, SN38 1TU). If unresolved, ask for a **'deadlock letter'** and escalate free to the **Consumer Council for Water (CCW)**, the independent body for water complaints. For failures to meet guaranteed standards you may be owed automatic GSS penalty payments, and Ofwat oversees the sector. Keep every email and note dates.

Why am I still being charged after cancelling Thames Water?

Usually one of three things: the cancellation never completed (no written confirmation), the subscription bills through Apple or Google and must be cancelled there, or a minimum term is still running. Charges continuing after a confirmed cancellation can be disputed with your bank as a chargeback.

How do I delete my Thames Water account?

Cancel the subscription first, then request account deletion in settings or by email. If there is no self-serve option, email a written erasure request citing the applicable data-protection law; most companies complete erasure within about 30 days.

How to Cancel Thames Water When You Move.

Q: Will I still be charged after I move out?

You shouldn't be, provided you tell Thames Water you're moving and give a closing meter reading. But **metered customers** who don't give at least 2 days' notice can be liable for charges for up to 28 days after Thames Water learns they've moved, until the next meter-read date or a new occupier confirms they've moved in. Always submit a reading on your move-out day and keep the confirmation.

Q: Does Thames Water charge a cancellation fee?

Rolling monthly plans end at the period already paid for with nothing extra to pay. Fixed minimum-term plans can carry an early-exit charge until the term ends, check your signup terms for a minimum-term end date.

Thames Water plans you can cancel

Household water & wastewater
Not a subscription, a regulated regional water/wastewater supply. You can only close the account when moving out of the Thames Water area, or set up a new account when moving in.
Wastewater-only
Some customers receive wastewater services only (water supplied by a different company). Closing still happens via the moving-home process.

What happens to what you’ve already paid

Thames Water doesn't run trials or refund windows like a normal subscription, refunds arise from account credit or overcharges. If your account is in credit, Thames Water typically uses that balance toward future bills rather than auto-refunding, but you can request the money back directly. A refund usually isn't possible while a bill is due or if they lack an up-to-date meter reading. When you move out, they issue a closing bill within six working days and settle any balance to your forwarding address.

“Once we have all the details of your move, we will send you a closing bill statement within six working days.”

Does Thames Water charge a cancellation fee?

We found no cancellation fee in Thames Water’s published terms. On a rolling plan you simply pay to the end of the current billing period and nothing after. If you’re inside a fixed minimum term, check your signup email for the end date, cancelling early is where fees usually hide. If you signed up online within the last 14 days, the Consumer Contracts Regulations give you a cooling-off right to walk away, fee-free, for most digital subscriptions.

What doesn’t work for cancelling Thames Water

Based on 6 sources, Reddit, app reviews, and direct testing. Skip these and save yourself the loop.

✕ Switching to a cheaper water supplier, Household water supply is a regional monopoly, you cannot switch your residential water supplier the way you can with energy. Only non-household (business) customers can switch retailer.
✕ Cancelling to stop paying while staying at the property, If you cancel your account you may be left without water, closing an account is only appropriate when you're leaving the supply area.
✕ Emailing customer service to close the account, Reddit/community reports show emails going unanswered; the account-closure route is the online moving-home form (or phone), and users hit form errors with no email reply.
✕ Expecting an automatic credit-balance refund, Thames Water applies credit to future bills rather than automatically refunding it, you must contact them to request the cash back.

Cancelled Thames Water but still being charged?

Three common reasons, in order of likelihood:

The cancellation didn’t actually complete. If you never received a written confirmation from Thames Water, treat it as not cancelled. Email customerservices@thameswater.co.uk referencing your original request date and ask for written confirmation plus a refund of any charge taken since.
You cancelled in the wrong place. Subscriptions started through the App Store or Google Play bill through Apple or Google, cancelling on Thames Water’s site doesn’t touch them. Check Settings → Subscriptions on iPhone, or Play Store → Payments & subscriptions on Android.
Billing lag. A charge that was already in flight when you cancelled can still land a few days later. One trailing charge can be normal; two is not.

If they keep charging after a confirmed cancellation, that’s chargeback territory: dispute the charge with your bank citing “subscription cancelled, merchant continued billing”. The yoink app also flags this automatically, it keeps watching your inbox after a confirmed cancellation and alerts you if Thames Water charges again.

How Thames Water will try to keep you

Thames Water may respond with a retention offer, a discount, a free month, or a downgrade to a cheaper tier. Don't engage with the counteroffer. Restate that you want a full cancellation and cite the consumer law again if they push back.

They’ll say: “Credit is 'kept for future bills' rather than refunded”
You say: You're entitled to request the credit back in cash. State clearly you want a refund to your bank account, provide a current meter reading, and confirm no bill is due. If they stall, cite Ofwat's guaranteed standards scheme.
They’ll say: “Slow or no response to written complaints”
You say: Send your complaint to customerservices@thameswater.co.uk and CC customer.feedback@thameswater.co.uk so there's a paper trail, community reports say a single mailbox often gets ignored. Their published SLA is a response within 10 working days.
They’ll say: “Unresolved complaint / deadlock”
You say: If Thames Water can't resolve it, request a 'deadlock letter' and escalate free to the Consumer Council for Water (CCW). For guaranteed-standards failures you may be owed automatic GSS penalty payments.
They’ll say: “Move-out timing traps for metered customers”
You say: Give at least 2 days' notice of your move and submit a meter reading on the day you leave. Metered customers who don't may stay liable for charges for up to 28 days after Thames Water learns you've moved.

Your rights when cancelling

The law where you live is the strongest hook, lead with it when you contact the company.

Worldwide

Card-issuer chargeback
Your bank can reverse the charge.
Visa, Mastercard, and Amex all run chargeback schemes, “goods/services not as described” or “subscription not cancelled” are valid reason codes everywhere they operate. Your bank handles the dispute; Thames Water has ~45 days to defend.

Delete your Thames Water account (not just cancel)

Cancelling stops the billing; deleting removes your account and personal data. Do them in that order, deleting an account with an active subscription can leave the billing running with no way to log in and stop it.

If there’s no delete option in Thames Water’s account settings, email customerservices@thameswater.co.uk with the subject Account deletion request, [your account email] and ask for your account and personal data to be erased under UK GDPR (Article 17, the right to erasure). They’re typically required to act on it, most companies complete erasure within about 30 days, and you should ask for written confirmation when it’s done.

Common questions about cancelling Thames Water

Thames Water isn't a subscription you cancel, you **close** the account when you move out of their supply area. Do it through your online account under moving home; the earliest you can tell them is **28 days** before your move date. Submit a final meter reading and a forwarding address, and they'll send a **closing bill within six working days**. If someone remains at the property, they'll need to set up their own account.
