Business Water Bill Checks for Manchester

Remote water bill reviews for Manchester businesses in the United Utilities area, including site area and drainage charge checks.

Local wholesaler: United Utilities (water and wastewater)

Business water in Manchester and the surrounding area

Manchester's business base is broad. The city centre is dominated by offices, hotels, bars and restaurants, alongside a large student population served by several universities and colleges. Around the edges there are logistics sites, manufacturing businesses and trading estates, with major retail and leisure destinations nearby. Neighbourhoods such as the Northern Quarter, Ancoats and Didsbury are full of small cafes, venues and shops. All of these businesses pay for water through bills that combine several different charges, and we review those bills remotely for Manchester businesses and organisations to look for errors and missed opportunities.

United Utilities: the regional wholesaler

United Utilities is the wholesaler for water and wastewater across Greater Manchester and the wider North West. It owns and maintains the pipes, sewers and treatment works and sets the wholesale charges that make up much of your bill. Your day-to-day contact, however, is your water retailer, which handles billing, meter reads and customer service.

One feature of business bills in the United Utilities area is that, for metered customers, surface water and highway drainage charges are based on the chargeable site area of your premises. United Utilities explains how that is calculated – including how roof area is shared between occupiers of the same building and how permanently grassed or landscaped areas are treated – on its guide to site area.

Choosing a retailer in England

The non-household retail market in England opened in April 2017, so most businesses, charities and public bodies in Manchester can choose their water retailer. The wholesaler stays the same whichever retailer you use. The Open Water eligibility guide explains which premises can switch.

A different retailer may offer different service levels or pricing on the retail element, but the underlying property data – meter details, site area, wastewater allowances – usually carries across. If that data is wrong, switching won't correct it. That is why we concentrate on whether your current bills are accurate. Our guide to reading a commercial water bill is a useful starting point if the layout is unfamiliar.

What we check for Manchester businesses

Site area and surface water drainage

Because drainage charges for metered sites in the region are linked to site area, it is worth checking that the area recorded for your premises is right. Common questions include whether a shared roof has been apportioned correctly, whether landscaped areas have been excluded, and whether a car park or yard actually drains to the public sewer. If rainwater from part of your site goes to a soakaway or watercourse instead, you may be able to reduce your charges. Our surface water drainage review covers this in more detail, and our article on what surface water drainage charges are explains the basics.

Hospitality and student accommodation

Hotels, restaurants, bars and purpose-built student housing can use a lot of water, and usage often follows trading seasons or term dates. We look at whether consumption matches those patterns, and whether any increases suggest a leak or a meter problem. See how we approach hospitality businesses and our tips on reducing water bills in hotels and restaurants.

Converted mills and older buildings

Manchester has many offices, flats and workspaces in converted warehouses and mills. Older plumbing, multiple historic connections and complicated ownership can mean meters are mislabelled, supplies are duplicated or unused connections still carry standing charges. Our tariff and standing charge review and consumption anomaly check are designed to pick up exactly these issues.

Sewerage charges for process water

Manufacturers, laundries, food producers and other businesses that use water in their processes may be paying sewerage on water that never reaches the drain. Our wastewater charge check looks at whether the allowance on your bill makes sense.

Several sites across Greater Manchester

If your organisation runs premises in several boroughs, our multi-site review compares them so that unusual charges or usage stand out. This is often useful for retail groups, care providers, schools and property managers.

When something has been wrong for a while

Where an issue seems to have affected past bills, our historic billing review sets out what may be worth raising with your retailer. Any correction depends on the circumstances and the rules that apply, so we treat it as a possibility rather than a promise. If you can't resolve a complaint with your retailer, the Consumer Council for Water offers advice and support for business customers. The UK Government is also planning to replace Ofwat with a new, single water regulator for England, following announcements in 2026; existing rules apply until those changes take effect.

Sending us bills from Manchester

We work remotely, so you don't need to arrange a visit. Send up to 12 months of water bills for each site through our secure upload page, along with any site plans or notes about drainage and water use if you have them. We'll review your charges and usage, send you a summary of possible findings, and explain any fees before any work goes ahead. Read our step-by-step process for more detail.

Useful questions for Manchester businesses

What does 'site area' mean on our Manchester water bill?

In the United Utilities area, surface water and highway drainage charges for metered business customers are based on the chargeable site area of your premises. That generally includes buildings and hard surfaces within your boundary, while permanently grassed or landscaped areas are excluded. If the area on record looks too large, or includes land you don't occupy, it is worth querying with your retailer.

We share a converted mill with other businesses. How is our drainage charge worked out?

Where a building has several occupiers, United Utilities apportions the roof area between them based on each occupier's share of the total floor area, and applies a similar approach to communal areas. If your share seems out of line with the space you actually occupy, ask your retailer how the figure was calculated and whether the floor areas are up to date.

Our car park drains into a soakaway. Do we still pay surface water charges for it?

If rainwater from part of your site doesn't drain, directly or indirectly, to a public sewer, you may be able to reduce your surface water charges. Evidence such as drainage plans, survey reports or photographs of the soakaway can support an application. Your retailer can explain the process for your site.

Our student accommodation uses far less water in summer. Should our bills reflect that?

If your bills are based on actual meter readings, they should show lower usage when the building is quieter. If they don't, the readings may be estimated or there may be a leak or fault. Comparing term-time and holiday consumption is a quick way to check whether the bills match how the building is used.

We moved into new premises in Salford. What should we check on the first bill?

Check the address, the meter serial number and opening read, the date your responsibility started, and that you aren't being charged for the previous occupier's usage. It is also worth confirming the chargeable site area used for drainage and that the tariffs are right for the type of business you run. Mistakes made when an account is set up can carry on for months if nobody spots them.

Manchester business water FAQs

Are you based in Manchester?

No. We review business water bills remotely for organisations across the UK, including Manchester, and we don't have an office or staff in the city. You send your bills through our secure upload page, and we'll contact you by email if we need more information about your site, such as how water is used or where rainwater drains.

Who supplies water and wastewater in Manchester?

United Utilities is the regional wholesaler for both water and wastewater across Greater Manchester and the wider North West. Your bill normally comes from a water retailer, which handles billing, meter reading and customer service, while United Utilities owns and runs the pipes, sewers and treatment works and sets the wholesale charges.

Why are drainage charges different in the North West?

For metered business customers, United Utilities bases surface water and highway drainage charges on chargeable site area. That means the accuracy of the area recorded for your premises can make a real difference. Other wholesalers use their own charging approaches.

Can I switch water retailer in Manchester?

Most non-household premises in England can choose a water retailer, and the Open Water website has an eligibility guide. Switching is a separate question from whether your bills are correct, though. Errors in the property data held for your site, such as site area or meter details, can carry straight over to a new retailer.

What happens after I upload my bills?

We review the charges and usage across the bills you send and prepare a summary of possible findings. If anything looks worth pursuing, we explain the options and any fees before any work goes ahead. Some bills turn out to be accurate, and we'll tell you if that's the case.
