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.

Common Reasons for a Meter Replacement
-
Faulty or damaged meter
If your meter has stopped registering usage, appears to be spinning too fast, or your bills no longer reflect what your business is actually using, it may need repairing or replacing. Wholesalers will typically survey the meter first to confirm the fault before scheduling a swap.
-
The wrong size for your business
It's common for a business to move into premises where a previous tenant used far more water. If you're a small office or shop running on a meter sized for a much larger operation, you could be paying inflated standing charges every month. This is one of the most common findings in a business water audit, so it's worth checking your meter size before you request a change.
-
An ageing meter
Many mechanical water meters are now well past 15 years old and are reaching the end of their working life. Wholesalers run ongoing replacement programmes to swap these out before they fail, and may contact you directly, through your retailer, when your meter is due.
-
Moving from unmetered to metered billing
Older buildings without a meter are billed on the rateable value of the property rather than actual water use. If that's costing you more than a metered supply would, you can ask your retailer to request a meter installation from the wholesaler.
-
Upgrading to a smart meter
Wholesalers across the UK are gradually rolling out digital and smart meters, which log usage daily rather than being read only once or twice a year. A smart meter makes it far easier to spot leaks early and track consumption trends, and some replacement programmes will fit one as standard when your old meter is due for a swap.

How to Request a Meter Replacement
- Contact your retailer first. Wholesalers only deal with licensed retailers, not directly with businesses, so this is always your starting point, not the wholesaler's website or call centre.
- Explain the issue clearly. Tell them whether you suspect a fault, believe your meter is the wrong size, want to move from an unmetered to a metered supply, or are asking about a smart meter upgrade.
- Your retailer raises a request with the wholesaler. They'll reference your SPID, the ten-digit code that identifies your specific water supply, when submitting it.
- The wholesaler arranges a site survey. This confirms the meter type, its location and whether there's safe access before any replacement date is agreed.
- The work is scheduled and carried out. Straightforward swaps can often be completed on the same visit; more complex jobs, such as those needing a new meter chamber, may need a second visit.
What Happens During a Meter Replacement Visit
For a standard like-for-like exchange, the engineer unscrews the old meter and fits the new one in its place. No digging is usually needed, and your internal pipework and water pressure shouldn't be affected. Your water supply will be briefly paused during the swap, so any equipment that relies on it, such as a washing machine or coffee machine, may need to be restarted manually afterwards.
Where a wholesaler is running a wider replacement programme, such as a smart meter rollout, they'll usually give advance notice before visiting and will try more than once to arrange a convenient time if the first attempt doesn't work.
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.
