An OCDEA Scheme for the Home Energy Model era

HEM-ready accreditation, software, and QA in a single workflow for faster, more reliable assessments.

Vulcan is built ground-up for the Home Energy Model to help you work faster, improve quality, and create more client value

Work faster

Vulcan integrates with existing workflows and files. Test HEM variants or create SAP inputs without re-entering data.

Improve quality

Proactive checks flag likely issues early. Dry-runs make quality assurance an opportunity to learn, not just be policed.

Create value

Generous lodgement limits for regulated work, plus unlimited non-regulated simulations so you can go beyond compliance.

Vulcan OCDEA membership: founding cohort

During the founding phase, we're offering Vulcan OCDEA membership with additional support for assessors who want to proactively prepare.

The Vulcan OCDEA member experience

Designed for volume modelling

Limitless local scenario analysis; batch ECaaS input & evidence upload; unlimited ECaaS compliance checks; and 50 ECaaS lodgements per month.

Wide learning opportunities

Learn from live sessions, office hours, and a community of peers on Slack. Access a library of HEM:FHS content and Vulcan walkthroughs.

QA that prevents problems

We meet required audit rules, but also invest upstream: with addtional guidance, opt-in quality assurance, and HEM-aware checks that catch common failure modes early.

Single workflow for building regulations and consultancy

Use the same tooling for HEM:FHS assessments and additional scenario modelling, to ensure consistent results and reduce rework. Vulcan's software is designed ground-up to make HEM easy to use.

Founding cohort

For OCDEAs who want to be visibly ready for HEM/FHS and cut rework.

  • Structured HEM/FHS ramp-up: practical conventions and workflow.
  • Review of your first HEM assessments to stabilise your approach early.
  • Direct input into Vulcan's scheme, QA, and product roadmap.

From £100/month per assessor

Apply for the founding cohort

Share a few details about your current role, how many new-build EPCs you work on per month, and what you most want to improve. We'll review applications and follow up with next steps.

We're keeping the cohort small so we can invest properly in each assessor. Clear answers here help us understand your work and whether Vulcan is a good fit.
