Energy Management for SMEs: Where to Start

The majority of UK SMEs managing between £10,000 and £150,000 a year in energy costs have never done a systematic energy review. Not because they don’t care about the cost — they do — but because energy feels like infrastructure: it arrives, you pay for it, and the interaction ends there. The bill spikes, there’s a conversation about it, nothing changes. The pattern repeats. This post is about breaking that pattern, and specifically about the sequence in which to do it — because the order matters considerably.

Why Most Energy Management Advice Starts in the Wrong Place

The conventional energy management narrative goes: measure your consumption, identify inefficiencies, invest in efficiency improvements, reduce consumption, save money. It’s logical in principle. In practice, for an SME that’s paying above-market rates on an inappropriately structured contract, efficiency investment before procurement review is like insulating a house before fixing a broken boiler. You can do it, but you’re not solving the primary problem first.

The right sequence is: get the procurement right first. Then measure. Then reduce. The reason procurement comes first is that it directly affects the value of every subsequent action. An SME that installs LED lighting and saves 15% on its lighting energy bill will see a different financial return depending on whether it’s paying 22p/kWh or 28p/kWh for its electricity. Get the price right, and the efficiency investments are worth more.

Step One: Get the Procurement Right

This means knowing what you’re currently paying, when your contracts expire, what the current market rate is for a business of your consumption profile and credit standing, and whether your contract structure is appropriate for your operational pattern. Most SMEs don’t know all four of these things simultaneously. They know their monthly bill; they may know the contract expiry date if they look hard enough; they don’t know current market rates because they’re not in the market; and they definitely don’t know whether their contract structure is optimal.

The output of good procurement is a competitive rate, an appropriate contract structure, and a known end date that you actively manage. From that point, every pound saved through efficiency improvement shows up at the right price per kWh.

Step Two: Measure What You Actually Consume

Half-hourly meter data is the most useful tool available to an SME for understanding its energy consumption. A 12-month dataset of half-hourly electricity consumption tells you: when you consume most (the peak demand periods that drive maximum demand charges), when you’re consuming energy needlessly (overnight baseloads that shouldn’t be there), and how your consumption compares between weekdays and weekends. Most SMEs on half-hourly meters can access their own data through their supplier’s portal. The problem is that almost nobody asks for it.

Step Three: Identify and Act on Reduction Opportunities

With a well-priced contract in place and consumption data in hand, you can assess efficiency opportunities against a clear financial baseline. The low-cost, high-return interventions available to most SMEs without specialist energy management consultancy are well established: LED lighting replacement (if not already done), timer and occupancy controls on lighting and HVAC, overnight and weekend baseload reduction, and hot water system temperature optimisation. Capital-intensive improvements — insulation, heat pumps, solar PV — require a proper investment appraisal against your actual contracted energy costs.

The Procurement Angle: This Is Where Telnergy Starts

The three-step sequence above describes how we approach new clients. Before any conversation about efficiency, technology, or sustainability, we establish what they’re paying, whether it’s competitive, and when their contracts expire. The first value we deliver is almost always procurement-related. Many of our clients have subsequently used the consumption picture we’ve assembled to support efficiency investment decisions, ESG reporting requirements, or planning applications for on-site generation. The data is the same data; the procurement work generates it as a byproduct.

FAQ

We’ve been quoted £5,000 for an energy audit from a consultant. Is that worth it? Possibly, but probably not as a first step. A comprehensive energy audit will identify efficiency opportunities and quantify their value — but the savings it identifies will be priced against your current energy rate, which may not be the best available rate. Our recommendation is to conduct the procurement review first (which costs nothing, since we work on supplier commission), then use the audited saving estimates recalculated against your new contracted rate to prioritise the efficiency investment list.

How long does it take to see a financial benefit from starting an energy management programme? Procurement savings begin on the first day of your new contract — immediately. Efficiency improvements vary: LED replacements deliver savings from installation; HVAC controls take a few weeks to optimise; insulation pays back over months to years. The combined effect typically delivers 15 to 30% reduction in total energy spend for an SME that has never actively managed energy, within the first 12 months of a structured programme.

We have three sites with three different suppliers and different contract end dates. Where do we start? Start with whichever contract is closest to its end date, or past its notice period. That’s your most urgent problem. While dealing with the immediate renewal, we’ll audit the other two contracts to establish their notice periods and current market competitiveness, and develop a strategy to align all three. Managing three independent renewal cycles is more complex than managing one combined cycle, and we’ll plan the path to alignment over the next contract cycle.
