Who Is Responsible for Replacing a Business Water Meter?
Your water meter belongs to your regional wholesaler, not to you and not to your retailer. Wholesalers such as Severn Trent, United Utilities and Thames Water own and maintain every meter connected to the public water network, including the one on your premises.
You cannot replace, remove or move a business water meter yourself, and you shouldn't try. Tampering with an active meter can breach your contract, and in some cases the law, so any physical work has to be carried out by the wholesaler or one of their accredited contractors.
Your retailer, the company that sends you your bill, is your first point of contact. They can't touch the meter themselves, but under Open Water rules only they can raise a service request with the wholesaler on your behalf. If you're not sure who your retailer is, it will be on your latest business water bill.

T+1, T+2, T+3: What the jargon means
Providers often describe payout speed using “T+n” shorthand. T is the day of the transaction, and the number is how many business days later the funds arrive.
- T+0 is same-day settlement, usually for a fee.
- T+1 is next-day settlement and the most common standard for UK card machines.
- T+2 or T+3 is standard settlement, and funds arrive two or three business days later.
Business days matter here, not calendar days. A transaction taken on a Friday under T+2 terms won't land until Tuesday, because the weekend doesn't count.
Why your first payouts often take longer
If you've just switched providers or taken out a new merchant account, don't be surprised if your first few payouts are slower than the timescale you were quoted.
Providers verify new merchant accounts before releasing funds at full speed. Some also hold back a small proportion of early takings, known as a rolling reserve, to cover the risk of refunds or chargebacks until they've built up a track record with your business. This is more common for higher-risk sectors, businesses with irregular transaction values, or those taking a lot of card-not-present payments online or over the phone.
This settles down once your account has a proven transaction history. It's worth asking your provider directly how long their onboarding hold typically lasts.
What slows a payout down
A handful of factors can push your payout outside the timescale your provider quoted:
- Weekends and bank holidays: banks do not settle funds on non-business days, so a Friday transaction can effectively add two or three extra days.
- Batch cut-off times: submit a transaction after your provider's daily cut-off, and it rolls into the next batch, adding a day.
- Card type: Amex often settles separately from Visa and Mastercard, since it acts as both the network and the issuing bank, which can add an extra step.
- Chargebacks and disputes: if a customer disputes a payment, your provider may hold the related funds while it's investigated.
- Unusual activity: a transaction that's much larger than your usual average, or a sudden spike in volume, can trigger extra fraud checks.
- Card-not-present and cross-border payments: online, phone and international transactions typically take longer to settle than a straightforward in-person tap or chip-and-PIN.
Does It Cost Anything?
| Faulty or damaged meter | Usually free. It's the wholesaler's asset, so repairing or replacing a genuine fault is on them. |
| Wholesaler-led upgrade programme (ageing meter, smart meter rollout) | Usually free, as it's an improvement to their own network. |
| New meter for an unmetered supply | May carry a wholesaler charge. Ask your retailer to confirm the cost before you go ahead. |
| Meter resize or relocation at your request | May carry a charge, especially where it's non-standard work like new chamber construction. |
Always ask your retailer to confirm costs upfront. Charges vary by wholesaler and by the type of work involved, so it's worth getting this in writing before any non-standard job goes ahead.
How Long Does It Take?
A simple like-for-like swap can often be done in a single site visit once it's been scheduled. Jobs that need extra work, such as installing a new meter chamber, resizing the meter, or gaining access to a hard-to-reach location, typically need a second visit and can take longer to complete. Your retailer should be able to give you a realistic timeframe once the wholesaler has surveyed the site.
Business Water Meter Replacement FAQs
-
Can I choose what type of meter I get?
You can ask, but the final decision sits with the wholesaler. They'll fit a meter that's appropriate for your supply size and location, and many are now defaulting to digital or smart meters where possible.
-
Will a meter replacement affect my water pressure?
No. A standard swap shouldn't change your water pressure or the quality of your supply. If you do notice a difference afterwards, report it to your retailer straight away.
-
Does replacing my meter change my SPID?
No. Your SPID identifies your supply point, not the physical meter itself, so it stays the same even after a replacement.
-
What if my bills don't match after the new meter is fitted?
A jump in readings after a faulty meter is replaced is usually expected, since the old meter may have been under-recording your usage. If the new figures look wrong, contact your retailer with your before-and-after readings so they can check it.
-
Can I refuse a meter upgrade my wholesaler wants to carry out?
You can raise concerns through your retailer, but wholesalers are generally entitled to maintain and upgrade their own network assets. If access is genuinely difficult, such as a locked plant room, tell your retailer so they can arrange a suitable time.
-
Could switching retailers also help?
A meter replacement is about the physical equipment, not your rates, but it's a natural moment to check whether you're still on a competitive deal. You can compare business water suppliers while you're waiting for the work to be scheduled.
-
Will I get a new business water meter when I move premises?
No. Usually, you will inherit the meter that is already there when you move premises, provided it is in working order.
