What is a multi-site water contract?

A single commercial arrangement that covers water cooler equipment and service across multiple offices for the same customer. Well-structured multi-site contracts provide consolidated invoicing, a named account manager, standardised equipment, per-site service records and pricing that reflects the whole portfolio.

How do I choose between a national chain and a regional operator for multi-site?

Start with where your sites are. If most sit within one region, a regional supplier whose own engineers cover that area can be a good fit. If your sites are spread across the whole UK, geographic reach becomes the deciding factor. Either way, ask which sites will be serviced by the supplier's own engineers and which by third parties.

What discount should I expect on a multi-site contract?

There is no standard figure. Pricing depends on the equipment, usage, number and spread of sites, installation work and the service level you need. Ask each supplier how their quote reflects the size of your portfolio, and compare what is included per site. Aquathirst provides a fixed monthly quote after a free site survey.

How is compliance documentation handled across sites?

A good multi-site supplier provides per-site Legionella risk assessments, sanitisation records, filter change logs and breakdown history, ideally in a central portal or annual audit pack. For customers with ISO 45001, CQC or HSE audit obligations, consolidated compliance documentation is worth more than per-cup cost savings.

Can I use different suppliers for different regions?

Yes, and for some portfolios it is the right answer. If your sites split naturally into two geographic clusters and no single supplier serves both regions well with their own engineers, two regional suppliers, each servicing its own cluster directly, can be a sensible structure. The trade-off is managing two relationships and keeping invoicing and compliance records consistent.

What is the minimum portfolio size for multi-site rates?

There is no fixed threshold. Consolidated invoicing and a named account contact can be useful from as few as two or three sites. Ask each supplier what multi-site arrangements they offer for a portfolio of your size and how pricing reflects it.

Multi-Site Water Contracts for UK Businesses: How to Get Them Right

The multi-site question

Multi-site facilities buyers face a specific version of the office water question that single-site buyers do not. It is not "which cooler" or "which supplier", because those questions have relatively clean answers. It is "how do we standardise the setup across all our sites so we get consistent service, consolidated billing and audit-ready compliance without spending three days a week managing it."

This guide is written for the person who owns the answer to that question: usually a facilities manager, office operations lead, or head of workplace services running between 3 and 50 sites. The single-site framework we cover in our supplier guide still applies. What follows is the additional layer that multi-site adds on top.

What a good multi-site contract actually looks like

Six things need to be true of a multi-site water and coffee contract to make it worth doing. If any of them are missing, you are running multiple single-site relationships with a shared logo, not a multi-site arrangement.

1. One invoice, per-site line items

Consolidated monthly invoicing across all sites, with each site itemised so your finance team can allocate costs to the right cost centre. If the supplier can only produce one flat total-across-all-sites figure, they cannot support your internal chargebacks.

2. One named account manager

A single point of contact who knows all your sites, understands your contract, and can escalate issues without transferring you through a call centre. For 3-15 sites, this is a person with a mobile number. For 20+ sites, it might be a small account team with a shared inbox and a lead contact.

3. Standardised equipment

Where possible, the same machine family across all sites. Standardisation simplifies training, spare parts inventory, service scheduling and staff mobility. Exceptions are legitimate for sites with genuinely different needs (a 400-person head office is not a 15-person satellite), but the default should be consistency.

4. Per-site service records

Every site should have its own service history, Legionella risk assessment, sanitisation record and breakdown log, accessible to you as a customer and not held internally by the supplier. Ideally in a portal you can log into. At minimum, supplied promptly on request.

5. Consistent breakdown response across all sites

Whatever breakdown response commitment you agree should apply to every site, not just the head office. If a supplier can only guarantee response time within their "core service area" and the outlying sites are longer, that is a legitimate operational reality but it should be transparent from the start, not discovered in a January outage.

6. Pricing that reflects the portfolio

Ask how the quote reflects the size of your portfolio. Consolidated delivery, servicing and account management can change the economics compared with contracting each site separately. If a supplier quotes a large portfolio exactly as it would a single site, ask why.

National chains vs regional operators

Multi-site coverage in 2026 can be structured in a few different ways. Each has trade-offs, and the right one depends on where your sites are.

Option	What to look for	Questions to ask
Supplier with national coverage	Geographic reach across all your sites, single invoicing, a clear contact route	Which sites are serviced by the supplier's own engineers and which by third parties? Does the breakdown commitment apply equally to every site?
Regional supplier with its own engineers	Directly employed engineers across its service area, direct account management	Which of your sites fall inside the service area? How would sites outside it be handled?
Two or more regional suppliers	Each supplier covering the cluster of sites it serves directly	Who owns each relationship internally? Can invoicing and compliance records be kept consistent across suppliers?

The realistic answer

Nobody services every postcode equally well

A claim of "full UK coverage" from any single supplier is worth unpacking. Ask where their own engineers operate and whether any regions are serviced by subcontractors. That is not necessarily a problem, but it affects how consistent service will be. A supplier who is clear about where their own operation reaches is easier to plan around.

When to consolidate to one supplier vs split across two

Not every multi-site portfolio should be with a single supplier. Sometimes the right answer is two regional operators with complementary footprints, each handling the geography they serve well.

Consolidating to one supplier makes sense when:

All (or most) sites sit within one supplier's own-serviced footprint
You value one invoice and one contact more than the marginal service quality difference on outlying sites
Consolidation makes a meaningful difference to cost or admin overhead
You do not have the internal capacity to manage two supplier relationships

Splitting across two suppliers makes sense when:

Your sites are geographically split into two natural clusters (e.g. south-east and north-west)
Service in one region has not met your needs under your current arrangement
You have the capacity to manage two account relationships with clear ownership
The service quality difference between the two operators is material to your operations

Compliance across a portfolio

The compliance overhead scales with site count. Every workplace with a water system needs Legionella risk assessment and documented sanitisation records. Across 20 sites that is 20 sets of paperwork, 20 service visit schedules, and 20 audit trails, so it is either something you have to manage internally or something you can outsource to the water supplier.

A good multi-site supplier provides:

Legionella risk assessment for each site, refreshed on a rolling basis
Sanitisation records for every scheduled service visit, per site
Filter change records with dates and cartridge specifications
Breakdown history per site for the year
A central portal or annual audit pack that consolidates all of the above

For customers with HSE audit or ISO 45001 certification obligations, this consolidated documentation is worth more than any per-cup cost saving. Ask what the compliance package looks like on the sales call. See our regulations piece for what the underlying obligations actually are.

What a multi-site setup usually costs

There is no standard multi-site price. Cost depends on the solution, usage, the sites themselves and the service you need. The table below sets out what tends to drive cost as a portfolio grows.

Portfolio size	Typical setup	Main cost drivers
3–5 sites	Mains-fed or bottle-fed coolers, sized per site	Equipment type per site, plumbing at each site, servicing frequency
6–15 sites	Standardised cooler model, some sites with boiling water taps	Number of sites, installation complexity, filters and sanitisation schedule
16–50 sites	Standardised equipment plus coffee at larger sites	Equipment mix, delivery planning across locations, reporting and compliance needs
50+ sites	Tailored arrangement, possibly split by region	Geographic spread, who services each region, account management structure

Other factors include contract length, rental versus purchase, delivery frequency for bottle-fed sites and CO2 for sparkling units. When comparing quotes, check what is included per site and ask about per-callout charges, bottle deposits, delivery surcharges, price-review clauses, auto-renewal and removal fees. Coffee equipment can be bundled onto the same contract with the same invoicing structure. Aquathirst provides a fixed monthly quote after a free site survey. See our office water cooler cost guide for the underlying single-site pricing framework.

How we handle multi-site

For multi-site businesses within our service area (London and the Home Counties), we can provide consolidated invoicing, a named account contact, per-site service records and standardised equipment. Servicing is carried out by our directly employed engineers, and breakdown support is included in your service agreement.

For portfolios that extend outside our service area, we will tell you plainly which sites we can serve and which we cannot, so you can plan the rest of the portfolio with the full picture. We would rather be clear about where our operation reaches than pretend we cover every postcode equally.
