Seasonal Energy Contracts

A caravan park in Dorset will consume three times as much electricity in August as it does in January. A garden centre hits its energy peak in spring and again at Christmas. A food processing site runs at 40% capacity in February and full tilt from September to December. In each case, the business is being served by a contract structure designed for a flat consumption pattern — and paying accordingly.

What a seasonal contract actually is

The term “seasonal contract” is used loosely in the energy market, and it’s worth being precise. A standard fixed-term contract commits you to a unit rate across a defined period, with an annual consumption estimate used as the basis for the offer. If your actual consumption is significantly higher or lower than that estimate in any given month, the contract doesn’t flex — you pay the fixed rate on whatever you consume.

A genuinely seasonal procurement structure is different. It may involve volume tolerance bands — a permitted range around the estimated consumption within which the unit rate holds. It may involve seasonal unit rates, where the pence-per-kWh charge is higher in peak months and lower in quiet ones, reflecting the actual cost of supplying energy when demand across the system is high. In some cases, it may involve take-or-pay provisions — a minimum volume commitment that the business must consume (or pay for regardless) to secure the contracted rate.

None of these structures are standard commercial energy contract terms. They require active negotiation, and they require a broker or energy manager who understands that the question “what’s your unit rate?” is not the right starting point for a seasonal business.

Who benefits from seasonal contract structures

The businesses that benefit most from seasonal procurement structures share a common characteristic: their energy consumption varies by more than 30 to 40% between their peak and trough months. Below that threshold, a well-priced standard fixed contract is usually the simpler and more cost-effective answer. Above it, the mismatch between a flat-priced contract and a peaked consumption pattern creates material cost.

Tourism and leisure businesses are the clearest case. A holiday park, a seaside hotel, or a coastal activity business is consuming heavily in summer and running on standby in winter. For these businesses, a fixed contract priced on the annual average is systematically overcharging in quiet periods. Agriculture and food processing are the other major category — seasonal growers, harvest-dependent processors, and cold storage operations tied to crop cycles have consumption profiles that are tightly linked to the agricultural calendar.

The risk of being locked into the wrong structure

The risk most seasonal businesses face isn’t that they’ll be explicitly penalised for consuming more than their estimate — it’s that they’re paying a rate that was calculated assuming a consumption pattern they don’t have. Suppliers price risk. A supplier who doesn’t know that your business runs at 20% of normal in January will price that uncertainty into your rate. A supplier who does know — because you’ve provided 12 months of half-hourly data showing the seasonal shape of your consumption — will price it out.

The other risk is contract end date timing. A seasonal business that auto-renews in October is going to market at the point of highest wholesale price pressure. Locking in a 12-month contract at an October peak and paying it through the following summer’s quiet period is an expensive way to manage energy. Actively managing your contract end date — aiming to renew in spring or early summer for most seasonal businesses — is a procurement decision that costs nothing to make and can be worth several percentage points on your annual rate.

The procurement angle: average is the enemy of accuracy

A standard fixed contract written for your average consumption is, almost by definition, wrong for a seasonal business. The supplier has built a margin around the uncertainty of your pattern — and that margin comes out of your budget. We approach seasonal business procurement by building a consumption model that shows the seasonal shape of the business month by month, then go to suppliers with that model and ask for pricing that reflects the actual consumption pattern, not the annual average. The difference in outcome can be significant.

FAQ

Can I negotiate a seasonal unit rate with any energy supplier? Seasonal rate structures are available from a subset of commercial energy suppliers and are not offered as standard products by most. They’re typically negotiated as bespoke terms for businesses that can demonstrate a clear seasonal profile and are willing to commit to a minimum volume. The negotiation is usually done through a broker with experience in non-standard contract structures.

We’re a tourism business that closes entirely for January and February. Do we need a contract in place during that period? Yes. An energy supply contract must remain active even when a premises is empty, because the connection to the network remains live. If you cancel your contract, the site falls onto the supplier’s deemed rate — typically 20 to 40% above your contracted rate. The correct approach is to ensure your contract covers the quiet months at a rate that reflects the low consumption you’ll actually have.

How far in advance should a seasonal business start its procurement process? Twelve months is not too early for a first conversation. We typically recommend starting the tender process four to six months before the contract end date, but beginning the analysis and data-gathering phase well before that. The worst-case scenario is a seasonal business that discovers its contract is auto-renewing six weeks before the end date — at which point the market options are limited.
