Is Affinity Water legit?
LegitAffinity Water is no fake: it supplies the taps from north-west London to the Kent coast, but clean water is the only part of the job it does. Sewers and blocked drains belong to Thames, Anglian or Southern Water, depending on your area, so a sewage problem is never Affinity's to fix.
What we checked
- Company registered in 1990
- Head office in Hatfield, Hertfordshire
- Ratings on other review websites: 3.5/5
Watch out for
- A first bill after moving in that rests on an estimated reading rather than the meter on the day you arrived.
- A leak on the supply pipe on your side of the meter, which Affinity's rules make yours to find and repair.
- Someone at the door claiming to be from Affinity Water who wants to go upstairs, something its staff never ask.
Affinity Water bill based on an estimated reading?
We help you write it, it gets its own public page, and you can have it sent to Affinity Water as a formal letter.

We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.
How do I contact Affinity Water customer service?
Call Affinity Water customer services on 0345 357 2401 for bills and accounts, or use the account and contact options on the Affinity Water website. For a leak, a burst pipe or no water, use the leak and supply route on the Affinity Water website, which lists a separate line for supply problems. Have the customer reference number from your bill and, for a metered account, a current meter reading ready.
Bill or meter reading in dispute? Bring it through our complaint process as well, and we push it out to Affinity Water by email, social media and printed letters.
How do I report a leak to Affinity Water?
To report a leak to Affinity Water, use the leak reporting route on its website or its supply line, give the exact location and what you can see, and note the reference number. A leak on a street or pavement is reported to Affinity Water directly. On your own property, the supply pipe between the boundary and the house is usually the owner's responsibility, so ask Affinity Water to confirm where the leak is before you pay a plumber. If a hidden leak pushed up a metered bill, ask whether a leakage allowance applies and keep the plumber's invoice for the repair.
Dated photos and the reference number show when the leak was reported.
Who handles sewerage for Affinity Water customers?
Affinity Water supplies drinking water only, so sewerage and wastewater for its customers are handled by Thames Water, Anglian Water or Southern Water, depending on where you live. A blocked sewer, sewage flooding or a problem with drains outside your property goes to that wastewater company, and Affinity Water's own complaints page sends complaints about the wastewater service there too.
Send each complaint to the company that runs that part of the service, with your account number for that company.
Can I complain to CCW (the Consumer Council for Water) about Affinity Water?
Yes: in England, CCW, the Consumer Council for Water, covers household customers of Affinity Water for their drinking water service. CCW generally expects Affinity Water to have had the chance to put things right first, so keep a record of every call, email and reference number.
Bill or leak allowance you want to challenge? We help you write the complaint in minutes, using what worked in thousands of earlier complaint letters.
How can I tell if an Affinity Water caller at my door is real?
Ask for ID before you let anyone in. Affinity Water says bogus callers posing as its staff, or as other utility workers, are a problem in some areas. Its real staff wear uniform, never ask to go upstairs, and will not mind waiting outside while you check their ID.
What do people complain about most at Affinity Water?
Nothing has been reported about Affinity Water here yet. Our research shows what typically goes wrong at water-only suppliers: bills that look too high or rest on estimated reads, leaks and disputes over who pays for the repair, low pressure and supply interruptions, delays with meter installation, and confusion over which company handles sewerage.
Leak repaired but the high bill left standing? Be the first to report it: your case opens the record for the next Affinity Water household with the same bill.
What happens after I submit my complaint?
Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of Affinity Water through emails, social media, paper complaint letters and other tools at our disposal.
And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.
Can other consumers help me with my Affinity Water complaint?
Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Affinity Water can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
