In short
Two proposals rarely describe the same work. Separate the services first, then compare on the same lines.

The short answer
Comparing consultancies is hard because two proposals rarely describe the same work. Put every proposal on the same page first: the same list of services, the same deliverables, the same payment basis, the same exit terms. Then compare.
The service types, separated
Most confusion comes from bundling. These are distinct pieces of work, with different effort and different outcomes, and a proposal should say which of them it includes.
| Service | Question it answers |
|---|---|
| Procurement or renewal | What should the next contract be, and with whom? |
| Invoice validation | Does each invoice match the contract that was signed? |
| Cost recovery | Has anything been charged in error, and can it be reclaimed? |
| Capacity review | Is the agreed capacity right for what the meter records? |
| Consumption and waste | What is being used that does not need to be used? |
| Compliance and reporting | Which obligations apply, and what evidence has to be filed and by when? |
| Bureau and administration | Who handles queries, changes of tenancy and the paperwork? |
A like-for-like sheet
Ask each consultancy to answer the same set of lines. Where an answer is not given, mark it as not given rather than assuming it is included.
- Services included, from the list above, and services excluded.
- Deliverables and how often each one arrives.
- Who does the work, and whether any part is subcontracted.
- Payment basis for each service, stated separately.
- What the authority document permits, and how it is limited.
- Term, notice period, and whether the agreement renews automatically.
- What data is returned at the end, and in what format.
- Named contact and response times for queries and disputes.
Comparing cost without comparing rates
A unit rate on its own is not comparable, because rates are quoted for different contract lengths, different capacity assumptions and different commission arrangements, and market prices move between one quote and the next.
Compare the total cost of the arrangement instead: the fee or commission for each service, the effort you have to supply, and what the work is expected to produce. A proposal that costs less because it excludes invoice checking is not cheaper, it is smaller.
What a comparison cannot settle
No sheet tells you whether a consultancy will do careful work. Comparison narrows the field on scope, payment and terms. Judgment on quality comes from references, from what a consultancy is willing to put in writing, and from how it behaves when the honest answer is that nothing is wrong.
Compare the evidence, not only the proposal
EV-02 / Procurement
£161,000 a year saved on gas, about £483,000 across a three-year term
Broadening Choices for Older People
Measured against the incumbent broker position on gas alone. Network and policy charges reset each April for every supplier alike, so those sector-wide movements are separated out and the comparison is like for like.
Client value summary, BCOP, 27 August 2026
EV-03 / Procurement
Group rates 10 per cent lower than the previous brokered prices
Roam
Measured against Roam's previous brokered prices with the 100 per cent REGO-backed renewable requirement held throughout, so the rate was not reduced by dropping the renewable commitment. Supplier volume tolerances were negotiated out to remove demand-risk exposure.
Client value summary, Roam, 27 August 2026
EV-05 / Consumption
Half-hourly waste analysis and full agreed-capacity audit completed
Broadening Choices for Older People
Consumption data turned into a costed picture of where energy is used unnecessarily, with reserved capacity right-sized across the estate. An on-site generation feasibility study was completed alongside it.
Client value summary, BCOP, 27 August 2026
The records above deliberately separate procurement, consumption and capacity work. That prevents unlike results being rolled into one headline and shows whether the service being compared is the service that produced the result.
Questions
What services do business energy consultancies provide?
Procurement or renewal, invoice validation, cost recovery, capacity review, consumption and waste work, compliance and reporting, and bureau administration. They are distinct pieces of work, so a proposal should state which of them it includes.
How do I compare energy consultancy proposals fairly?
Ask each one to answer the same lines: services included and excluded, deliverables and their frequency, who does the work, payment basis per service, what the authority permits, term and notice, and what data is returned at the end.
Why can I not just compare the unit rate?
Rates are quoted for different contract lengths, capacity assumptions and commission arrangements, and market prices move between quotes. Compare the total cost of the arrangement and what the work produces instead.
