Business water for hospitality

A boutique hotel we work with had been on the same water retailer since 2017. The bill was a stable line in the monthly accounts. Then the manager started looking at it during a kitchen refit. Three meters, one of which she didn’t recognise. Trade effluent on the bar that nobody had reviewed since the previous tenant. A standing charge structure that made no sense for a thirty-room property. None of it dramatic. All of it adding up.

Hospitality water is harder than most sectors. Hotels run laundry around the clock, plus the kitchen, plus the bathrooms in every guest room. Pubs peak in July and August then drop off, but the meter doesn’t stop. Restaurants carry trade effluent on the kitchen and surface water on the terrace. Most sites have three to six separate meters and most accounts haven’t been reviewed in years.

This page covers how we help hospitality businesses get a clearer view of what they’re paying. The mechanics of switching are covered in our main business water switching guide. Our business water service covers the open UK market across every commercial sector.

How we help hospitality businesses

We start by getting every meter on your site into a single view. Most operators don’t have one. Bills come in separately, from different retailers in some cases, and nobody has a complete picture of what each meter actually does.

Once the meter list is in front of us, we run through the contract terms, the retailer margin, the standing charges and the wastewater side of each bill. The retailer rate is usually the headline number, but it’s not always where the biggest saving sits. Standing charges multiplied across multiple meters can be worth more than a unit-rate adjustment. Trade effluent assessments that haven’t been reviewed since the kitchen was last refitted are a common source of overpay. Surface water drainage on a terrace, beer garden or staff car park is another.

From there we pull live quotes from the retailers operating in your wholesaler region, compare like-for-like, and tell you which one would suit your usage profile. If you decide to switch, the new retailer handles the transition. There’s no break in supply at any point and no engineer visits the property.

Why hospitality water is different from a typical SME account

An average small business account is one meter, one building, one occupancy pattern. Hospitality is almost never that.

Trade effluent: the line most kitchens overpay on

Anywhere a commercial kitchen discharges wastewater, the wholesaler can charge for trade effluent on top of standard wastewater. The assessment is set when the kitchen first applies for consent and rarely reviewed again. Kitchens change. Menus change. Volumes change. The trade effluent line typically does not.

For a pub-restaurant or hotel kitchen, the trade effluent assessment is worth reviewing every few years. The Mogden formula values that drive the charge are sensitive to the type of food being prepared, the volume of wash-down, and the grease trap arrangement. We’ve seen kitchens still being charged against a discharge profile that hasn’t matched their actual operation for half a decade.

Seasonal demand and how it lands on the bill

The cleaner the meter reading, the easier the seasonal pattern is to manage. Hotels in coastal and tourist regions can see July and August consumption two or three times higher than November. Pubs follow a similar curve. City-centre business hotels run the opposite way: stable Tuesday-to-Thursday occupancy, drops at weekends.

The problem isn’t the seasonal pattern itself. It’s estimated reads. If the wholesaler hasn’t actually read your meter for several quarters, the bill is built on a guess. When the catch-up read eventually lands, the resulting invoice arrives at the wrong time of year for cash flow. Either it overshoots the peak and produces a refund, or it undershoots and produces a budget hit. Monthly or quarterly actual reads remove the surprise. We’ll flag any meter that’s been estimated for more than two cycles.

Multi-site groups and portfolio reviews

For pub groups, hotel chains and restaurant groups, water is rarely managed centrally. Sites get added, leases change, retailers vary by region. By the time a finance director looks at the consolidated picture, there are often five or six retailers across the estate, multiple renewal dates and inconsistent contract terms.

Consolidating onto a single retailer with one renewal cycle is usually the right move for groups of more than three or four sites. The unit rate matters, but the bigger value is administrative: one bill, one renewal review, one point of contact when something goes wrong. We’ve coordinated portfolio switches across regional pub groups and small hotel collections where the saving was less in pence-per-cubic-metre and more in finance team hours reclaimed.

How a hospitality water review works

Most operators ask the same question on a first call. “What do you need from us and how long is it going to take?” The honest answer is a recent bill from each site and roughly half an hour of someone’s time.

Hospitality water terms worth knowing

SPID

Supply Point Identification number. Every meter has its own SPID.

Trade effluent

Wastewater from commercial activity. Almost any commercial kitchen needs a trade effluent consent.

Mogden formula

The pricing formula wholesalers use to set trade effluent charges, based on volume, organic load and suspended solids.

Surface water drainage (SWD)

Charges for rainwater running off impermeable surfaces into the public sewer. Terraces and car parks count; gardens and grass typically do not.

Deemed contract

The default tariff a site sits on if no contract is in place. Almost always the most expensive option.

Letter of authority

Permission to act on your behalf with retailers and wholesalers. Doesn’t commit you to switching.
