Business energy procurement strategy: fixed rates, brokers & risks

Energy prices can move fast. If you buy without a plan, you could overpay. If you're a large or industrial business with high energy use, costs can run into five or even six figures.

A procurement strategy is a plan for how and when you buy energy for your business. Get it right, and you can protect your margins for years, not just one contract term.

This guide breaks procurement down into plain steps. It covers buying methods, risk, brokers, and long-term planning, so you can make a choice that fits your business.

In this guide to energy procurement strategy…

• We show you how to manage price and budget risk as a small business
• We explain what brokers and TPIs do, and how to pick one you can trust
• We cover long-term planning, including half-hourly metering and renewable contracts.

What is energy procurement?

Energy procurement is the process of buying gas and electricity for your business at the best available price and on the best available terms.

It covers more than picking a supplier. Procurement includes when you buy, how much risk you take on, who you buy through, and how often you review your contract.

For most small firms, procurement means switching suppliers every one to three years and locking in a fixed rate. For larger firms, it can mean buying energy in stages across several years, tracking wholesale markets, and managing a dedicated energy budget.

In short: energy procurement is a plan, not a single purchase. The strategy behind it can be the difference between paying the rate or an inflated one.

Your procurement strategy matters more than any single switch. A good rate agreed at the wrong time can still cost you more than a fair rate agreed with a clear plan behind it.

Why procurement strategy matters for SMEs

Most small businesses don't think about procurement. They wait for the renewal letter, compare quotes, and pick the most suitable one.

That approach usually works and is fine up to a point. But if your business uses a lot of gas and electricity, it can leave savings on the table and can expose you to price spikes if you switch at the wrong point in the market.

A basic strategy costs nothing to set up - simply follow the steps below:

• Review your contract end date early, not after it has passed
• Decide in advance whether you want price certainty or flexibility
• Know your usage pattern, so you buy the right size of contract
• Set a calendar reminder to compare the market again next year.

Non-commodity costs, such as network charges and green levies, can make up around 60% of a typical UK business electricity bill. This means the wholesale price you lock in is only part of what you pay, and it's one more reason to plan your buying rather than react to it.

SME vs large business: which applies to you?

Procurement advice changes depending on your size. Use these thresholds to work out where you sit.

Business type	Typical usage	Metering	Buying approach
Micro and small business	Under 55,000 kWh electricity or 200,000 kWh gas a year	Standard meter*	Fixed-rate contract, switched every 1–3 years
Medium business	Approaching the thresholds above	Standard or half-hourly meter	Fixed rate with closer market monitoring
Large business	55,000 kWh+ electricity or 200,000 kWh+ gas a year	Often half-hourly	Flexible or staged buying, bespoke contracts

*All standard meters are currently being switched to half-hourly settlement. Find out more in our guide to Market-wide Half-Hourly Settlement (MHHS).

If you fall under these usage levels, most of this guide's fixed-rate advice applies directly to you. If you're close to or above them, the flexible buying and risk sections below matter more.

Fixed vs flexible purchasing

There are three main ways to buy business energy. Each carries a different balance of cost and risk.

Fixed-rate purchasing

You agree on one unit rate for the full length of your contract, usually one to three years.

• Your rate stays the same, whatever happens to the wholesale market
• Budgeting is simple, since your energy cost is known in advance
• You could miss out if wholesale prices fall after you sign.

This is the right fit for most SMEs. It removes price risk and needs no market monitoring.

Flexible purchasing

You buy energy in stages over time, rather than locking in a single rate

• You can buy more when prices dip and hold off when they spike
• It needs regular monitoring, or a broker managing it for you
• It suits businesses with higher usage and some budget to absorb price swings.

Spot purchasing

You buy energy at the current market price, with no fixed contract.

• Rates change constantly, sometimes daily
• It carries the highest risk, since bills can rise sharply with no warning
• Some large industrial users choose this deliberately to bet on falling prices.

Most small businesses should avoid spot purchasing altogether. The savings potential does not usually outweigh the risk to cash flow.

Risk management strategies

Buying energy always carries some risk. The goal of a strategy is not to remove risk completely. It's to manage it so it doesn't damage your business.

Key risks to plan for:

• Price risk: wholesale costs rising between now and your renewal
• Timing risk: switching too close to a price spike, or too far ahead of a market dip
• Contract risk: signing terms with hidden exit fees or automatic rollovers
• Usage risk: your consumption changing due to growth, downsizing, or new equipment.

Ways to manage these risks:

1. Start comparing quotes three to six months before your contract ends, not after
2. Ask for a breakdown of standing charges and unit rates, not just a headline price
3. Check your contract for automatic renewal clauses before you sign
4. Review your usage each year so your contract still matches your business.

For most SMEs, a fixed-rate contract agreed early is the simplest form of risk management. It removes the guesswork around timing the market.

Can businesses hedge energy costs?

Hedging means locking in some or all of your energy price in advance to protect against future price rises.

For SMEs, hedging usually happens automatically when you sign a fixed-rate contract. Your supplier buys the wholesale energy on your behalf and holds that rate for your contract term.

Larger businesses with flexible contracts can hedge more directly. This involves buying set portions of their forecast usage at different points across the year. This spreads risk across several price points, rather than betting on one.

What is the role of brokers and TPIs?

A broker, sometimes called a Third Party Intermediary or TPI, compares the market on your behalf and negotiates rates with suppliers.

Business energy brokers can offer:

• Access to rates not always available directly from suppliers.
• Market knowledge on when prices are likely to move.
• Time saved, since they handle quotes and paperwork for you.

What does TPI Code of Practice membership mean?

The TPI Code of Practice is a set of standards that some brokers voluntarily sign up to. It's not a legal requirement, but it sets a bar for fair conduct.

A broker that follows the TPI Code of Practice agrees to give clear pricing, disclose any commission it earns, and avoid pressure-selling tactics. This matters because unregulated brokers can add hidden commission to your rate without telling you.

When you compare brokers, ask directly whether they follow the Code and how they're paid. A broker that avoids the question is a warning sign. Our partners at Bionic always let you know what their commission will be before you sign a contract. 

How to choose a business energy broker

1. Check how they're paid. Ask whether they earn commission from the supplier, and how much. This affects the rate you're offered.
2. Ask how many suppliers they cover. A broker tied to one or two suppliers can't give you a fair market view.
3. Look for TPI Code of Practice membership. This signals a baseline of transparency and fair dealing.
4. Ask for a written quote comparison. A broker should show you the options, not just their preferred deal.
5. Check reviews and how long they've operated. Longevity and independent reviews give a sense of reliability.

When you get a quote with MoneySuperMarket, our partners at Bionic compare quotes from a panel of trusted suppliers so you can see your options clearly before you commit.

How to put a long-term energy plan in place

A procurement strategy works best when it looks beyond your next renewal.

Build a review calendar

Set a fixed point each year to review your contract, even if it isn't close to ending. Prices move, and a contract that was competitive last year may not be this year.

Consider half-hourly metering

If your usage is approaching the large business thresholds, a half-hourly meter gives your supplier accurate, time-of-use data. This can open up more flexible and potentially cheaper contract options.

Look at Power Purchase Agreements (PPAs)

A Power Purchase Agreement is a long-term contract to buy renewable electricity directly from a generator, often at a fixed rate over several years.

PPAs suit businesses that want price certainty alongside a renewable energy commitment. They're more common among larger energy users, but interest from growing SMEs is rising as clean energy contracts become more accessible.

Match your contract length to your business plans

A short contract gives flexibility if you expect to move premises or change usage. A longer, fixed contract suits businesses that value price certainty over flexibility.

Business energy procurement FAQs

Still unsure about energy procurement? Check out the answers to our most frequently asked questions.

What is the best procurement method for SMEs?

For most small and micro businesses, a fixed-rate contract is the simplest and lowest-risk option. It gives price certainty without the need to monitor wholesale markets.

Do small businesses need procurement strategies?

Yes. Even a basic plan, such as reviewing your contract early and comparing the market each year, protects you from overpaying or rolling onto a poor default rate.

Are brokers worth using?

Brokers can save time and give access to rates not always available direct. Check how they're paid and whether they follow the TPI Code of Practice before you commit.

How do large firms buy energy differently?

Large firms, typically using 55,000 kWh+ of electricity or 200,000 kWh+ of gas a year, often buy in stages through flexible contracts and use half-hourly metering to manage cost and risk more closely.

What risks should businesses manage?

The main risks are price risk, timing risk, contract risk, and usage risk. A clear strategy, reviewed yearly, helps manage all four.

Is forward buying possible for SMEs?

Forward buying, or hedging, is more common in flexible contracts used by larger businesses. Most SMEs achieve a similar effect simply by fixing their rate early, before their current contract ends.

Can businesses hedge energy costs?

Yes. Fixed-rate contracts act as a simple hedge for SMEs. Larger businesses can hedge more directly by buying set portions of forecast usage at different price points.

How often should strategy be reviewed?

At least once a year. Reviewing annually protects against rising non-commodity costs and stops you rolling onto an uncompetitive rate by default.
