What does a business energy consultant do?
Strategy, purchasing, usage and compliance, for a fee. When it’s worth paying for, and when a broker gets you the same outcome without one.
A business energy consultant analyses how your organisation buys and uses energy, then turns that into decisions. Which contract structure, when to buy, where consumption can fall, and how to stay on the right side of compliance.
Quick snapshot
- Consultants advise on strategy, purchasing, usage and compliance; brokers compare the market and execute the switch.
- You don’t need a consultant to switch suppliers. That’s broker work, funded by commission rather than a fee.
- Consultancy starts paying for itself on large or complex estates, roughly 500 MWh a year and up.
What does a business energy consultant actually do?
The core of the work is procurement strategy rather than price-picking. A consultant will profile your consumption, decide whether fixed or flexible purchasing suits the business, time the buying, and manage the contract through its life rather than reappearing at renewal.
Around that sits the analysis. Bill and tariff audits, capacity reviews on half-hourly sites, compliance work such as ESOS, and increasingly net zero and carbon reporting plans. A broker, by contrast, is focused on comparing the market and executing the switch. Same industry, different centre of gravity.
When should a business hire an energy consultant?
When the decisions get bigger than the price per kWh. In practice that means portfolios above roughly 500 MWh a year, multi-site estates, half-hourly supplies with capacity or power-factor questions, compliance deadlines, or a board asking for a net zero plan with numbers in it.
Below that threshold the honest answer is that consultancy rarely pays its way, because the procurement piece is already covered by broker commission. A single-site office asking a consultant to run its renewal is paying for a service the market provides free.
Do I need an energy consultant to switch suppliers?
No. Switching is broker work. It’s funded by supplier commission, so a whole-of-market broker will run the comparison, handle the paperwork and manage the transfer without charging you a fee. A consultant adds value on top of switching, not instead of it.
What fees do business energy consultants charge?
Day rates, monthly retainers, or a share of evidenced savings. Scope drives the number more than anything else, and the same brief can be quoted very differently by an independent specialist and a large consultancy. Whatever the model, get the basis in writing and ask what happens if no savings materialise.
Worth knowing before you commit: much of what consultants sell to smaller businesses, renewals management, bill checking, market monitoring, is included in a decent broker’s managed service. Ours is funded the way we describe on how we make our money.
Consultant or broker, which does your business need?
Most UK SMEs need a broker. Large or complex estates often benefit from both, sometimes in the same firm. We’ve set out the differences, overlaps and the questions to ask in our full comparison of energy consultants and brokers.
Frequently asked questions
What’s the difference between an energy consultant and an energy broker?
A broker compares the market and executes the switch, paid by supplier commission. A consultant advises on strategy, purchasing, usage and compliance, usually for a fee. Plenty of firms blur the line. We’ve unpicked it properly in our guide to energy consultants vs brokers.
How much does a business energy consultant cost in the UK?
Three fee models dominate: a day rate, a monthly retainer for ongoing management, or a share of evidenced savings. Costs vary widely with scope and the consultant’s specialism, so treat any published price list with suspicion and get the fee basis in writing before work starts.
Is an energy consultant worth it for a small business?
Usually not on procurement alone. A whole-of-market broker will compare and switch a small business at no separate fee, which covers most of what a small firm needs. Consultancy starts earning its fee when consumption is large, sites multiply, or compliance obligations like ESOS enter the picture.
