Running a growing business means constantly weighing where to spend and where to cut back, and one cost category that gets far less scrutiny than it deserves is energy. While owners will happily spend hours comparing software subscriptions or negotiating supplier discounts on stock, the electricity and gas contract sitting quietly in the background often goes unreviewed for years, even as rates shift and better deals become available elsewhere.
The Problem With Letting Contracts Roll Over
Business energy does not work like household energy. There is no price cap protecting commercial customers, and rates are set through individually negotiated contracts that vary based on usage, contract length, and how recently a business last compared the market. A business that lets its contract renew automatically at the end of its term is almost always accepting a worse deal than what is currently available, since suppliers rarely put their most competitive rate in front of a customer who has not gone looking for one.
This matters more for growing businesses than it might seem. As usage increases with headcount, equipment, or expanded premises, the gap between a competitive rate and an outdated one widens in absolute terms, even if the percentage difference stays the same.
What a Proper Energy Review Actually Involves
A meaningful review goes beyond glancing at a monthly bill. It means understanding current market rates across multiple suppliers, checking contract structures and standing charges, and paying close attention to renewal notice periods, which are often buried in the fine print and easy to miss until the window to switch has already closed.
This is exactly the kind of work that specialist energy consultancies exist to handle.GLCG works with UK businesses to compare electricity, gas and water contracts across the market, checking unit rates and standing charges together to identify the deal that costs the least over the full contract term rather than just the one with the lowest headline price.
Where the Money Actually Gets Lost
Missing a renewal notice window is the most common pattern, since it typically means rolling onto a supplier’s default rate. Mismatched contract length is another, where a business locks into a long fixed term during a period of high market prices, or conversely stays on a short rolling contract that leaves it exposed to volatility it did not intend to take on.
Standing charges deserve particular attention too. These fixed daily fees apply regardless of actual usage and have risen across the UK commercial energy market in recent years.
Building Energy Review Into Normal Operations
The businesses that manage this well tend to treat energy contract review as a recurring item rather than a one-time fix. Setting a calendar reminder well ahead of a contract’s renewal date, reviewing usage patterns annually, and staying broadly aware of market direction all help avoid the trap of quietly overpaying for years at a stretch.
This mirrors how growing businesses already treat other major cost lines. Marketing spend gets measured against results. Software gets audited for unused licenses. Energy deserves the same ongoing attention.
A Reasonable Place to Start
For any business that has not looked closely at its energy contracts recently, the simplest starting point is pulling the last year of bills, checking the current contract’s end date and notice period, and comparing that against what is currently available in the market.
The Bigger Picture for Growing Businesses
None of this requires overhauling how a business operates day to day. It simply requires treating energy the same way a well-run business already treats its other major costs: reviewed on a schedule, benchmarked against the current market, and renegotiated whenever a better deal is genuinely available. For a business scaling quickly, that discipline compounds, freeing up cash that can go toward hiring, equipment, or growth rather than quietly funding a supplier’s margin on a contract nobody remembered to check.
Frequently Asked Questions
Why don’t UK businesses get the same energy price protection as households?
The energy price cap applies only to domestic consumers. Business electricity and gas are priced through negotiated commercial contracts, so the rate depends entirely on market conditions and how actively a business compares suppliers.
How often should a growing business review its energy contract?
At least annually, and ideally well before the current contract’s renewal notice period, since missing that window often means defaulting to a more expensive rate.
Is it worth bringing in a consultancy rather than comparing rates independently?
For most businesses without dedicated procurement staff, a specialist consultancy can track market movement and supplier terms more thoroughly than an internal review.
What is a renewal notice period and why does it matter so much?
It is the window before a contract ends during which a business must notify its supplier if it wants to switch. Missing it typically means rolling onto a more expensive default rate.
Why have standing charges become more significant in recent years?
Standing charges are fixed daily fees that apply regardless of usage, and they have risen across the UK commercial energy market, making them an increasingly large share of the total bill for lower-usage businesses.
