Case study
How Roam reduced group rates by 10 per cent across 800 charge point sites
Renewable held.Risk removed.Rates down.
The account
A UK-wide charge point network of more than 800 sites, already brokered, with a 100 per cent renewable commitment that could not be compromised and demand that is genuinely hard to forecast site by site.
- Client
- Roam
- Sector
- Electric vehicle charging, UK wide
- Sites
- More than 800 charge point sites across the UK
The result
Each figure is shown with what it is measured against, the document it is taken from and the date that document carries.
EV-03 / Procurement
Group rates 10 per cent lower than the previous brokered prices
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.

EV-06 / Carbon
100 per cent REGO-backed renewable supply maintained in full
Stated as REGO-backed rather than as an unqualified renewable claim, because REGO means the electricity is matched to certified renewable generation. The backing is named so the claim can be checked.

What we examined
The work starts with the records the client already holds. Nothing is estimated where a document exists.
- The previous brokered prices across the group.
- The renewable backing attached to the existing supply.
- Volume tolerance terms in the supplier contracts, and the exposure they carried.
- Site and meter records across the network, held as one schedule.
What the reading showed
- Group rates had not been tested against the market with the renewable requirement held in place.
- Supplier volume tolerances left the network exposed to demand risk it could not control.
- Charging demand varies by site and season, which makes a single forecast unreliable.
What was done
Each step was recommended in writing and agreed before it was carried out.
01
The group was tendered with the 100 per cent REGO-backed renewable requirement held throughout, so the rate was not reduced by dropping the commitment.
02
Supplier volume tolerances were negotiated out, removing demand-risk exposure from the contract.
03
The renewable backing was recorded as REGO-backed, so the claim can be checked rather than taken on trust.
How to read the figure
The 10 per cent is measured against Roam's previous brokered prices, with the renewable requirement unchanged on both sides of the comparison. The supply is described as 100 per cent REGO-backed rather than as an unqualified renewable claim, because REGO means the electricity is matched to certified renewable generation.
