Utilities are one of the largest recurring costs a business carries, and for many companies they are also one of the least examined. Water and electricity bills arrive, get paid, and are rarely questioned, even though both are competitive markets where a business can compare suppliers and switch to a better deal. Reviewing these two utilities together is one of the most effective ways to reduce overheads without changing anything about how the business operates. This guide explains how to cut both your water and electricity costs.
Why Utilities Are Worth Reviewing
The reason utilities reward attention is simple. They are recurring, so any saving returns every single month and adds up across the year. They are also usually left on autopilot, with contracts rolling over unexamined while rates quietly climb. That combination, a large recurring cost that nobody reviews, is exactly where overpayment hides.
Both water and electricity are open to competition for business customers, which means you are not tied to whichever supplier you inherited. You can compare the market and switch, and because the physical supply is unaffected by a switch, there is no operational risk in doing so. The only thing that changes is the rate and the contract behind the bill.
Electricity: Usually the Bigger Prize
For most businesses, electricity is the larger of the two bills, which makes it the first place to look. The bill is built around a unit rate, the price you pay for each unit of energy used, and a standing charge, a fixed daily amount you pay regardless of usage. The unit rate is where most of the cost sits, and it is set by your contract, reflecting the market at the time you signed.
Because energy prices move constantly, a rate agreed a couple of years ago can sit well above what is available now. Comparing your tariff with a service such as business electricity comparison shows current rates from multiple UK suppliers side by side, so you can judge whether your deal is still competitive. If it is not, switching lowers the cost of every unit you use for the length of the new contract, which for most businesses is a meaningful saving.
Alongside the rate, reducing usage helps too. Efficient lighting, sensible heating and cooling, and well maintained equipment all lower consumption. The strongest approach combines a competitive rate with lower usage, so you pay less per unit and use fewer units.
Water: The Overlooked Saving
Water is the quieter bill, which is precisely why it is so often overlooked. Yet almost every business pays for both clean water supply and wastewater, and over a year the total is far from trivial. In England the business water market is open to competition, so a business can choose the retailer that bills it rather than staying with the default regional supplier.
Reviewing your business water contract can uncover lower standing charges, corrected billing, and the chance to consolidate several sites onto one contract. Common wins include catching estimated readings that overstate usage and removing surface water drainage charges that do not apply to your site. Because the retailer handles billing rather than the pipes, switching leaves your actual water supply completely unchanged.
Reviewing Both Together
The most efficient approach is to review water and electricity in the same exercise. Gather your recent bills for both, note your rates, standing charges, consumption, and contract end dates, and compare each against the market. Handling them together gives you a complete view of your utility spend and ensures neither is left to drift onto an uncompetitive rate.
It also simplifies the routine. Once a year, ideally a couple of months before each contract renews, review both utilities, compare the market, and switch where a better deal exists. This single habit keeps two of your largest recurring costs lean, and it takes little time relative to what it saves.
Timing Matters for Both
For both water and electricity, timing is the detail that catches businesses out. Contracts have end dates, and letting one lapse without arranging a new deal often means rolling onto an expensive default or deemed rate. Knowing your end dates and reviewing the market before them means you move onto a competitive new contract rather than drifting onto a costly one. Diarising your renewals is a simple safeguard that protects the savings you work to secure.
Frequently Asked Questions
Can a business switch both water and electricity suppliers?
Yes. In England both the business water and business energy markets are open to competition, so a business can compare suppliers and switch to better contracts for each.
Will switching interrupt my supply?
No. For both utilities, switching is a billing change handled between suppliers. The physical supply of water and electricity to your premises is unaffected, so there is no interruption.
Which utility should I review first?
Usually electricity, since it is typically the larger bill and offers the bigger saving. But reviewing both together is best, since it gives a full view and keeps neither on an uncompetitive rate.
What savings are common on water?
Lower standing charges, corrected billing from estimated readings, removal of surface water drainage charges that do not apply, and consolidating multiple sites onto one contract.
How often should I review my utilities?
At least once a year, and a couple of months before each contract renews, so you can compare the market and switch before an automatic rollover onto a higher rate.
Final Thought
Water and electricity are among the largest recurring costs a business carries, and both are more controllable than most owners assume. Compare your electricity rate and reduce your usage, review your water contract for errors and better terms, and handle both on a yearly routine timed around your renewals. Done together, these steps turn two overlooked bills into a reliable, repeating saving.
