ESOS in Scotland, done properly and priced fairly.
If your organisation is large enough to fall under ESOS, we run the whole thing for you, audit, report and Lead Assessor sign-off, and hand you a clear list of savings worth acting on, with no jargon and no scramble before the deadline. Registered in Scotland? Your regulator is SEPA, and we handle that side too.
In Scotland, SEPA enforces ESOS.
For organisations whose registered office is in Scotland, SEPA is the body that enforces ESOS. It monitors compliance and can issue civil sanctions, including financial penalties, where an organisation does not meet its obligations.
Who SEPA regulates
Organisations whose registered office is in Scotland. If you are part of a group, the group’s registered arrangements decide which UK regulator you deal with, not where each site sits.
What SEPA does
SEPA checks compliance and can apply civil sanctions, including financial penalties, for organisations that fail to comply, in line with its wider regulatory approach.
How you notify
Notification is made through the UK-wide “Managing your ESOS” (MESOS) system, which we handle for you; your compliance then sits with SEPA as your regulator.
Scottish support to act on it
Scotland has its own energy-efficiency support, including Business Energy Scotland, that can help you take forward the measures your audit identifies.

Whatever your regulator, the audit itself is run by the same ESOS consultants who handle ESOS across the UK.
The same obligations, whoever your regulator is.
Wherever your organisation sits, ESOS asks the same of you: the same thresholds, the same 5 December 2027 deadline and the same penalties. We handle the whole thing for you either way.

Four steps. We do the heavy lifting.
From the first scoping call to the notification receipt, you have one point of contact and a price agreed up front against a scope we map with you.
Scope & quote
A short call and a desktop review to confirm you qualify and map every site, so we scope the work properly and agree a clear price against it.
Data & audit
We gather energy data and carry out the audits, buildings, processes and transport, with minimal disruption to your operation.
Report & sign-off
Your Lead Assessor compiles the report, ranks the savings, and provides the compliant sign-off for your director.
Notify & save
We submit your notification through the national ESOS system and leave you with a clear plan to act on the savings.
Compliance closed, and a return on the work.

ESOS in Scotland: common questions.
Who regulates ESOS in Scotland?
SEPA, the Scottish Environment Protection Agency, is the ESOS regulator for organisations whose registered office is in Scotland. It monitors compliance and can issue civil penalties. The scheme itself is UK-wide and identical to the rest of the UK; only the enforcing regulator differs.
Is ESOS different in Scotland?
No. ESOS is a single UK-wide scheme made under UK regulations, so the qualification thresholds, the four-yearly phases, the deadlines and the penalties are exactly the same in Scotland as in the rest of the UK. The one difference is that SEPA, rather than the Environment Agency, is the body that enforces it for Scottish-registered organisations.
Our registered office is in Scotland but we have sites across the UK — who is our regulator?
Your regulator is generally determined by where your organisation or group is registered, not where each site is, so a Scottish-registered organisation deals with SEPA even when its sites and energy are spread across the UK. We confirm the right regulator for your structure as part of scoping.
How do I know if ESOS applies to us?
ESOS applies to large UK undertakings and their corporate groups: broadly, 250 or more employees, or turnover over £44m and a balance sheet over £38m. If any company in a group qualifies, the whole group is in. The eligibility check on our homepage is the quickest way to find out.
What does it cost?
It depends on your scope: your sites, and how your energy splits across buildings, transport and process. That is what the free scoping call establishes, and we then agree a clear price for the defined work up front, with no open-ended day rates.
Engineers who understand your energy, not just the paperwork.
