What do energy consultants do?

Energy consultants help organisations reduce energy costs, improve building performance, meet compliance requirements such as ESOS and SECR, and deliver practical net zero strategies.

How much does energy consultancy cost?

Costs vary depending on scope, but Zerith offers flexible delivery models including traditional consultancy and ZECO AI-enabled in-house delivery, which can reduce consultancy costs by up to 70%.

What is ESOS compliance?

The Energy Savings Opportunity Scheme (ESOS) is a UK regulatory requirement for large organisations to assess energy use and identify cost-effective energy savings opportunities.

Can energy consultancy be delivered in-house?

Yes. Zerith offers ZECO AI, enabling organisations to manage energy and compliance internally, supported by expert consultancy and lead assessor sign-off where required.

What does a commercial energy audit include?

A commercial energy audit assesses building systems, energy consumption, and operational performance to identify cost-saving and optimisation opportunities across HVAC, lighting, BeMS, and wider building infrastructure.

How much can an energy audit save?

Most organisations achieve 5–10% reductions in energy costs through targeted optimisation measures, with additional savings available through behavioural and system improvements.

What is the typical payback period for energy improvements?

Typical payback periods range from 12 to 24 months depending on the complexity of the site and the measures implemented.

Can energy audits be delivered in-house?

Yes. Zerith offers a ZECO AI-enabled delivery model that allows organisations to deliver energy audits and optimisation programmes in-house, supported by Zerith expertise and compliance sign-off where required.

Do you support ESOS compliance?

Yes. Zerith provides full ESOS compliance support, including audits, reporting, and Lead Assessor sign-off.
