Part L 2025 Is Coming: What Architects Need to Do Now

The next revision of England’s Part L ramps up energy‑efficiency targets for every new dwelling. We unpack the draft requirements, show how early SAP modelling avoids last‑minute fabric upgrades, and share a checklist you can start using on projects breaking ground in 2026.

Too Much Glass? How to Pass the 25 % Rule Without Sacrificing Your View

Floor‑to‑ceiling glazing can sink a planning application if you blow the 25 % heat‑loss limit. Learn three design tweaks—floor‑zone insulation, low‑g glazing, and strategic overhangs—that our assessors use to keep statement extensions bright and compliant across England’s varied climates.

Overheating Risk Maps: Where Dynamic Thermal Modelling Beats the Simplified Method

With the introduction of Part O, London isn’t the only hotspot. We compare hourly simulation data from Manchester, Bristol and Norfolk to the simplified method results, revealing when full dynamic modelling is worth the fee—and how it can unlock design freedom for nationwide developers.

Frequently Asked Questions

  • Engage us as early as RIBA Stage 3 (planning) so design tweaks are cheap and programme‑neutral. We final‑seal certificates at Stage 5, but early modelling lets you lock budgets, placate fund monitors, and avoid last‑minute spec shocks.

  • Absolutely. We exchange BIM/DWG files, join weekly design‑team calls, and maintain a revision log so everyone—architect, M&E, QS—iterates from the same data set.

  • Yes. We align SAP/SBEM evidence with each block’s practical‑completion date, issuing interim EPCs where needed so sales, funding‑drawdowns, and warranties stay on schedule.

  • Fixed‑price modelling, fair‑use revisions, liaison with Planning and Building Control, signed certificates (SAP, SBEM, EPC, TM59, LZC), and a compliance statement for fund monitors—no hidden extras.

  • Every report is produced in‑house by CIBSE & Elmhurst‑accredited engineers and independently quality‑checked, giving you bank‑grade documentation accepted nationwide.
