NZEB / TGD L & Part L Compliance Consultancy
Clear guidance through Ireland's TGD L and the UK's Part L requirements — so new build and major renovation projects meet Nearly Zero Energy Building standards without late-stage surprises.
Compliance is mandatory — the route you take to it isn't
All new buildings across Ireland and the UK must now meet Nearly Zero Energy Building standards, driven by the EU Energy Performance of Buildings Directive and implemented locally through TGD L and Part L. Getting the compliance strategy right early protects budget, timeline and planning approval.
We guide architects, engineers, developers and public bodies through the regulatory landscape, from concept design through to final certification, so compliance is designed in rather than retrofitted.
- ✓Future-proof investment — NZEB-compliant buildings meet current and near-term regulation, protecting asset value.
- ✓Design integration — We work directly with your design team to embed compliant fabric, HVAC and renewables choices.
- ✓Material & system selection — Practical guidance on insulation, glazing, heat pumps and renewable technology to hit targets cost-effectively.
- ✓Certification support — Full documentation and evidence prepared for BER/EPC assessors and building control.

FAQs
Is NZEB compliance mandatory in Ireland?
Yes. Under the EU Energy Performance of Buildings Directive, all new buildings in Ireland must meet the Nearly Zero Energy Building (NZEB) standard set out in TGD L.
How does TGD L differ from Part L in the UK?
TGD L is the Irish Technical Guidance Document implementing NZEB requirements, while Part L governs energy efficiency in England and Wales, with equivalent regulations in Scotland and Northern Ireland. We work across both frameworks.
At what project stage should NZEB modelling start?
As early as possible. Involving compliance modelling at concept design avoids costly redesign later and gives more flexibility in material and system selection.
