How to get ahead as a Non-Domestic Energy Assessor in 2026

As 2026 approaches, non-domestic energy assessors are poised to seize a growing array of opportunities. From engaging with the evolving Minimum Energy Efficiency Standards (MEES) and non-domestic retrofit programs (PAS 2038), to offering expert advice across a full spectrum of non-domestic energy services.

Non-Domestic MEES

What we know: The Government still hasn’t published its response to the non-domestic MEES consultation. The latest expectation is that we’ll see this in early 2026, which is likely to kick-start a fresh wave of compliance activity across the year.

What we expect to happen: While nothing is confirmed yet, the direction of travel is pretty clear: minimum EPC requirements for privately rented non-domestic buildings are likely to tighten. Industry conversation has long pointed towards EPC B as a future target, but for now the legal minimum in England and Wales remains EPC E until any new rules, guidance and enforcement arrangements are formally introduced.

What is the opportunity for Non-Domestic professionals?

Once the Government response is published, we’d expect demand to rise for EPCs, advisory support and compliance-ready evidence, helping landlords stay lettable and plan upgrades with confidence. We are also likely to see an increase in interest for the retrofit of non-domestic buildings which opens up a new opportunity for NDEAs.

Non-Domestic Retrofit & PAS 2038

What we know: PAS 2038 is the recognised standard for non-domestic retrofit. It provides a structured, whole-building framework for planning and delivering energy performance improvements across a wide range of non-domestic building types, which expands outside of MEES requirements.

What we expect to happen: As retrofit activity increases, driven by net zero targets, rising energy costs and compliance pressures such as uplifted MEES, PAS 2038 is likely to be used more consistently to structure projects. This should increase demand for PAS 2038 retrofit planning and robust quality assurance throughout delivery.

What is the opportunity for Non-Domestic professionals?

Now is the perfect time for Non-Domestic Energy Assessors to start getting up to speed with PAS 2038 and understanding it’s role within Non-Domestic Retrofit. Elmhurst have already launched an introduction course to cover this subject and introduce Non-Domestic Energy Assessors to this concept.

While assessment is a key part of the process, retrofit projects also rely on input across design, coordination, installation oversight and verification, opening up varied routes for NDEAs and other non-domestic professionals to broaden their services and support clients.

Expanding into different competencies

Non-domestic clients rarely have just one requirement. Alongside EPCs, many are managing a mix of compliance and building performance priorities, often across multiple sites, so they’re looking for support that covers more than one area. By upskilling into additional competencies such as Air Conditioning Inspections, ESOS Lead Assessment or Overheating, you can offer a broader, more joined-up service to your clients.

This is where upskilling really pays off. Expanding your competencies helps you stay confident and compliant in the work you deliver, while giving clients reassurance that you can support the bigger picture, not just a single assessment. It also helps build longer-term relationships and opens up opportunities to grow your services in a way that genuinely reflects what clients need.
