Energy Costs and Business Valuation

A business spending £150,000 per year on energy at rates 20% above market is carrying an EBITDA drag of £30,000 annually. At a five-times earnings multiple — modest for most SME trade sales — that overpayment represents £150,000 of enterprise value destroyed. When a buyer’s due diligence team pulls three years of energy contracts and runs them against market rates for the same periods, that calculation appears in the information memorandum. It becomes a negotiating point, not an administrative detail.

How energy contracts appear in M&A due diligence

Business acquisitions routinely include a review of material contracts, and energy supply agreements are material for most trading businesses with significant energy spend. A buyer will look for several specific risk factors. Auto-renewal clauses that have triggered without active engagement — resulting in a contract at above-market rates — represent both a current overpayment and evidence of weak supplier management. Exit fees that would crystallise on a change of ownership transfer a contingent liability to the buyer unless separately negotiated out of the transaction. And change-of-control provisions — clauses that allow the supplier to renegotiate terms or terminate on a change of business ownership — are present in more commercial energy contracts than most vendors realise, and are rarely checked during pre-sale preparation.

The change-of-control issue is the most commonly missed. A business that has negotiated a favourable 3-year fixed contract may find it contains a clause allowing the supplier to review pricing or terminate with notice if ownership changes. Where a deal is structured as a share purchase, the legal entity holding the contract doesn’t change, but some contracts define change of control at the level of the underlying business or its directors. This requires careful reading and, if the clause is present, either a supplier consent process pre-completion or a price adjustment mechanism in the transaction itself.

Energy as a signal in a buyer’s risk assessment

Beyond the direct financial impact of overpayment, energy contract management sends a signal about the quality of operational management more broadly. A business with contracts renewed on time, rates benchmarked against market, and clean billing history presents differently from one with rolling auto-renewals, disputed invoices, and no record of procurement review. Neither is a deal-breaker on its own, but the former supports a premium valuation narrative while the latter contributes to a discount.

For strategic buyers who will integrate the business into their operations, the specific energy contract terms may matter less than for financial buyers who need to model the cost base accurately for their investment case. A private equity acquirer building a buy-and-build platform will pay close attention to whether energy contracts can be aggregated post-acquisition, what the exit costs are, and whether the combined entity’s procurement can be centralised.

Planning a sale: the 3-year horizon

The optimal position for a business entering a sale process is to have its energy contracts in order well before the process begins. Specifically: contracts renewed at market rates within the preceding 18 months, exit fees minimal or approaching natural expiry, auto-renewal traps avoided, and any change-of-control clauses identified and either accepted or addressed. A vendor who can present clean energy contract documentation — with rate evidence and a straightforward handover path — removes a due diligence friction point and a negotiating lever.

Businesses planning a sale within 3–5 years should bring their energy procurement strategy into pre-sale preparation alongside tax structuring, management accounts normalisation, and other standard vendor readiness work. It is consistently lower on the priority list than it should be, and consistently more impactful when buyers find problems than sellers expect.

The procurement connection

Telnergy works with business owners preparing for sale on both the audit and the rectification. We review existing contracts for change-of-control provisions, auto-renewal status, and rate competitiveness, and where remediation is needed — renewing contracts at market rates or managing exit from disadvantageous terms — we manage that process. The cost of a pre-sale energy contract review is typically a fraction of the valuation impact of an unchecked energy contract position.

FAQ

We’re selling next year. Our energy contract auto-renewed six months ago at above-market rates. What are our options? First, calculate the exit fee — most fixed contracts specify this as a per-day, per-unit, or fixed-sum charge in the pricing schedule. Compare that cost against the saving from switching to a market-rate contract for the remaining term. If the numbers work, switch now and present the buyer with a clean, competitive contract. If the exit fee is prohibitive, disclose the position transparently in due diligence and model the remaining term cost into your pricing expectations. Buyers will find it regardless; a vendor who has already quantified it demonstrates control rather than oversight.

Do energy contracts always contain change-of-control clauses? No — it varies by supplier and contract. Larger, more sophisticated suppliers are more likely to include them. The clause typically allows the supplier to review pricing or terminate with 30 days’ notice on a change of control or material change in the business. In practice, most suppliers use this as a pricing review trigger rather than an exit mechanism, but the legal exposure needs to be understood before signing a sale agreement. Your energy broker should confirm whether your contracts contain such provisions as part of any pre-sale review.

Can a buyer use our energy costs to negotiate down the purchase price? Yes, and it is a standard tactic. If due diligence identifies energy costs running above market rates, a buyer will typically request a price adjustment representing the NPV of the overpayment for the remaining contract term, require the vendor to exit disadvantageous contracts pre-completion, or use it as a component of a broader working capital or cost-base adjustment. Removing the issue before the process starts is almost always preferable to negotiating it out of the price under deadline pressure.
