Business gas prices per kWh: Factor in ESOS plans

The lowest quoted unit rate is not automatically the best gas contract for your organisation. When comparing business gas prices per kWh, the figures should be assessed against the amount of gas you realistically expect to use over the contract term.

This matters when your ESOS action plan includes measures intended to reduce gas consumption. If improvements will change demand, historic consumption alone may give suppliers the wrong basis for pricing. To identify the best business gas prices for your requirements, your forecast should reflect credible efficiency plans as well as current usage.

What should you review before requesting gas quotes?

Before seeking commercial gas quotes, bring together:

• recent, reliable gas consumption data for every site included in the contract
• the implementation dates and estimated gas savings associated with approved ESOS measures
• known operational, occupancy or estate changes that may increase or reduce demand
• the required contract start date, term and approach to risk
• unit rates, standing charges and any other applicable costs or contractual elements
• provisions addressing material differences between forecast and actual consumption
• Treating this information as one procurement brief gives suppliers a consistent demand profile to price and gives decision-makers a clearer basis for comparison

Why the price per kWh is only part of the gas contract decision

Business gas prices per kWh show the charge applied to each unit of gas consumed, but they do not show the whole projected contract cost. For example, standing charges are fixed daily fees for access to gas and electricity, regardless of consumption. Supplier quotations may also be prepared using different consumption figures or may exclude certain charges or contractual elements.

That is why the best business gas prices should not be selected by ranking unit rates alone. First check that each quotation uses the same forecast volume, sites, contract period and requested contract structure. Then review the unit rate alongside standing charges and every other cost or condition that affects the comparison.

A simple evaluation model is: Forecast gas consumption × quoted unit rate + standing charges + other applicable contract costs = projected contract cost

This comparison tool does not replace a review of the supplier’s full terms, but it can prevent an attractive headline rate from obscuring a less suitable overall position.

Forecast gas demand after planned ESOS measures

The Energy Savings Opportunity Scheme (ESOS) helps qualifying organisations identify opportunities to improve energy efficiency. Our ESOS service supports the compliance process, including action plans and annual progress updates, while our ESOS dashboard can present identified opportunities, estimated savings, implementation costs and payback periods.

For gas procurement, the practical question is: which measures are sufficiently developed to affect consumption during the next contract?

1. Establish a reliable baseline: Start with accurate consumption data for the sites and meters within the new contract. Check whether the period is representative and document known changes that affected demand. Our Metering and Data Services and Portal can support greater visibility of usage, costs and reporting.

• An accurate baseline helps ensure comparisons of gas business prices begin with a defensible view of current demand, rather than incomplete or inconsistent information.

2. Map ESOS measures to the contract period: Review the measures in your ESOS action plan and separate them by status: already implemented, approved with a delivery date, under consideration, or not currently planned. Give most weight to measures that have internal approval, a credible programme and an estimated effect on gas consumption.

• For each approved measure, record the affected site, expected completion date, estimated annual gas saving and the proportion of that saving likely to fall within each contract year. This converts the action plan into inputs that a procurement specialist can test against the proposed contract term.

3. Allow for uncertainty: Estimated savings are not the same as achieved reductions. Project timings can move, operational requirements can change and the realised impact may differ from the original estimate.

• Where delivery is uncertain, prepare a base forecast and reasonable higher- and lower-consumption scenarios. This supports discussion of contract structure and volume risk without presenting planned savings as guaranteed.

Compare commercial gas quotes using consistent volumes

To compare commercial gas quotes fairly, issue the same procurement information to every supplier being considered. A consistent brief should state the expected annual consumption, site and meter portfolio, contract start date, term and any material changes already included in the forecast.

When the quotations return, check:

• whether the same consumption profile has been priced
• whether the unit rate and standing charge are presented consistently
• which other charges or contractual elements are included or excluded
• whether the proposed supplier, contract length and contract type fit your budget requirements and risk tolerance
• how the contract addresses actual consumption that differs from the forecast

This approach makes business gas prices per kWh easier to compare while keeping attention on total value and contract suitability. It also reduces the risk of treating quotes based on different assumptions as though they were equivalent.

Review tolerance and volume-risk considerations

Our energy procurement service assesses fixed, flexible and green energy options against factors including consumption, budget requirements, risk tolerance and market conditions. If ESOS measures are expected to alter gas demand, the treatment of volume variance should form part of that assessment.

Ask whether the proposed contract contains consumption tolerances, how these are measured and what happens if actual usage is materially above or below forecast. The relevance of these provisions will depend on the supplier, product and contract terms, so they should be verified for each option rather than assumed.

The objective is not simply to secure the lowest business gas prices per kWh available on the day. It is to select a contract that reflects expected requirements and an acceptable level of risk.

Use SECR data to monitor whether reductions are being achieved

Our Streamlined Energy and Carbon Reporting service reduces compliance complexity while improving visibility and control over energy and emissions data. That evidence can help organisations monitor whether efficiency actions are translating into lower gas consumption.

Compare actual gas use with the baseline and the savings trajectory used for procurement. Where results differ materially, investigate the reason and update the forecast before the next buying decision. This creates a feedback loop between planned measures, achieved performance and future contract assumptions.

SECR is not a live gas-procurement tool, but its structured data and narrative on efficiency action can help test whether the demand assumptions behind gas business prices remain credible.

Bring compliance, efficiency and procurement decisions together

We support organisations across ESOS, SECR and energy procurement. Together, these services can help procurement teams use reliable consumption data and compare contract options against operational and budget requirements.

This coordinated approach can help you:

• use ESOS opportunities and action plans to inform future demand
• compare commercial gas quotes on a like-for-like basis
• assess contract choice against consumption, budget and risk tolerance
• use SECR reporting to review progress and strengthen future forecasts

Evidence in practice

Our work with Glenmorangie shows how targeted building optimisation can materially change gas demand. The case study reports an estimated 52% annual reduction in gas consumption following data-led improvements. The result is organisation-specific, but it demonstrates why planned and implemented efficiency projects should not sit separately from contract forecasting.
