Meter installation for households in England and Wales, per Ofwat
Portsmouth Water supplies Portsmouth and surrounding areas. This page covers the move-in steps in the company's own terms: how to register as the new occupier, what the first bill is based on, how to get a meter and whether you can go back, and the help it publishes for households that cannot afford the bill.
How do I tell Portsmouth Water I have moved in?
You do not choose Portsmouth Water: the address does. The job is telling it the right date so the charges start when your tenancy or ownership did.
- CCW lists Portsmouth Water's area as Portsmouth and surrounding areas.
- Portsmouth Water: its change of address or new customer form asks for your previous address and the date you left, your new address and the date you moved in, final and first meter readings if there is a meter, the number of bedrooms and occupants, and whether you rent.
- Portsmouth Water: moves more than 14 days ahead are processed nearer the move date, and it contacts you only if it has questions.
- Ofwat: under the current legislation, household customers are not able to change their water supplier or sewerage service provider. The company that supplies your property depends on where you live.

Read the meter on the day you move in
If the home has a water meter, take a reading as soon as you move in. CCW says this ensures accurate billing, and a dated photo of the dial settles any later question about the opening figure.

Tell Portsmouth Water your move-in date
Portsmouth Water's online form asks for your previous and new addresses, the dates you left and moved in, final and first meter readings, the number of bedrooms and occupants, and whether you rent. Give the date your tenancy or ownership started.
- 3
Check the first bill against that date
The first bill should start on your move-in date, use your opening reading if there is a meter, and show whether sewerage is on the same bill or comes from a second company.
What is my first Portsmouth Water bill based on?
Two systems run side by side: a meter measures what you use, and an unmetered home is charged on a valuation that has nothing to do with usage.
- Portsmouth Water: if it has told you that you are moving to metering, for the first 12 months it automatically charges whichever is lower, the charges with or without a meter, and shows a comparison on each bill.
- Portsmouth Water: metered bills come every six months, based on how much water you use, and your wastewater company, usually Southern Water, also bases its bills on your readings.
- Ofwat: if you do not have a water meter, your bill is not based on how much water you use. It is usually a fixed charge plus a charge based on the rateable value of your home, a valuation last updated in 1990.
- CCW: if your new home already has a water meter, you must pay metered charges based on your usage and you cannot switch to an unmetered bill. Take a reading as soon as you move in.
- CCW: a water company can install a meter when you move in, but not if you have already received an unmetered bill for that property. It tells you when you report the move.
- Ofwat: you may receive your water supply from one company and your sewerage services from another, which means you may get two separate bills.

Can I get a water meter from Portsmouth Water, and can I switch back?
A meter is the only lever a household has on this bill, so the question is whether you can try one without being stuck with it.
- Portsmouth Water: asked whether you have to have a meter, it answers yes.
- Portsmouth Water: it is bringing smart water meters to all the homes it supplies by 2035.
- Portsmouth Water: the Lowest Bill Promise ends 12 months after you receive your final closing bill, and it keeps in touch during that period so you know when metered billing starts.
- Portsmouth Water: if you are on WaterSure or its Helping Hand social tariff, you already pay the lowest charge.
- Ofwat: household customers in England and Wales can choose to have a meter fitted in their homes free of charge. If a meter cannot be fitted, the company must offer an assessed charge instead.
- Ofwat: in England, where the company is legally obliged to act on your request, it must begin measuring your supply within eight weeks of the day you ask.
- CCW: you can usually switch back to the unmetered charge within two years if you are unhappy with the change, except for customers in areas of England where compulsory metering is introduced. Where the company publishes its own rule, as above, that is the one to go by.
- CCW: you can ask for a water meter to be fitted if you rent your home in England.

What if there is a leak, or a dispute with Portsmouth Water?
- Portsmouth Water: billing and account enquiries are answered Monday to Friday, 8am to 5pm. For water meter enquiries call 023 9249 9666, and its 24-hour Freephone leak line is 0800 434 6104.
- CCW: the homeowner is responsible for maintaining the water pipes on private property up to the boundary of the road. The water main, the connection up to your boundary, the outside stop tap and the meter are the company's.
- Ofwat: companies are required by their licences to reimburse the cost of water lost through leakage by way of credits to your bill, a leakage allowance that can apply to water and wastewater charges. You can only claim once the leak has been repaired, and it can be refused if you did not arrange the repair within the company's timeframe.
- CCW: complain to the company first and give it a chance to put things right. If it does not reply within 10 working days you may be entitled to a Guaranteed Standards Scheme payment. CCW can take the complaint on once you have a final response or have waited eight weeks, and its service is free.

Does Taupia switch my water from Portsmouth Water?
No, and nobody can. There is no water market for households, so there is no commission in this bill and nothing for a comparison site to sell you.
- Taupia keeps the Portsmouth Water account next to your energy, broadband and mobile: what it costs, when it is due, and each housemate's share on the rule your household sets.
- For energy, broadband and mobile, Taupia compares your tariff against the market and lines up a switch when one is worth it. Water is monitored only, because it cannot be switched.
- Taupia is free. You pay the water company directly, as you always have, and nothing changes without your approval.

Questions movers ask about Portsmouth Water
Can I switch from Portsmouth Water to a cheaper water company?
No. Ofwat says household customers cannot change their water supplier or sewerage provider, because the company depends on where you live. Portsmouth Water is the company for your address, and the only choice you get is how you are charged: on a meter, or on the property's unmetered charge.
Do I need to tell Portsmouth Water when I move in?
Yes, and as soon as you can. Portsmouth Water's online form asks for your previous and new addresses, the dates you left and moved in, final and first meter readings, the number of bedrooms and occupants, and whether you rent. Give the date you became responsible for the property.
What is an unmetered Portsmouth Water bill based on?
If Portsmouth Water has told you that you are moving to metering, for the first 12 months it charges whichever is lower, with or without a meter, and shows a comparison on each bill. Using less water does not change an unmetered bill, because nothing is measured. A metered home pays for the water recorded plus a standing charge.
Can I switch back to unmetered charges with Portsmouth Water?
Portsmouth Water says you have to have a meter, and it is bringing smart meters to all the homes it supplies by 2035. Instead of a switch back, homes moved to metering get a 12 month Lowest Bill Promise. Check the current terms with the company before you apply.
What help does Portsmouth Water give if I cannot afford the water bill?
Portsmouth Water's Helping Hand tariff caps the bill at its minimum charge for households with an income of £22,020 or under, and WaterSure caps metered bills at the average metered bill, £162.82 from 1 April 2026. Ask early: CCW says companies can also offer payment plans and, in some cases, payment breaks.
Does Taupia switch my water supplier from Portsmouth Water?
No, because nobody can. Water is a regional monopoly with no household market, so Taupia monitors the bill rather than switching it. It sits alongside your energy, broadband and mobile, where switching is possible, with the due date and each housemate's share. Taupia is free and you keep paying the water company directly.
