Domestic retrofit · Whole-house approach
EAC South West helps homeowners, designers and builders plan and verify energy-efficient upgrades — from baseline assessments to post-works testing. We align with PAS 2035 principles and coordinate related Part L/F items so you get practical, buildable advice.
Retrofitting means adding modern, energy-efficient measures to homes built without them — cutting running costs and reducing environmental impact. It’s a key part of the UK’s strategy to lower emissions by improving the performance of existing dwellings.
Before & after. We can assess the current property (if no assessment exists) and model projected performance once retrofit measures are installed.
Process
We review the dwelling, any SAP/EPC data, and your goals to set realistic targets for comfort, energy and cost.
We outline coordinated, fabric-first measures (insulation, airtightness, thermal bridges), efficient services and ventilation.
We incorporate airtightness and ventilation testing results and refine the design for the best overall outcome.
PAS 2035 governs the retrofit process for improved energy efficiency. It considers the home, local environment, occupancy and your objectives to select suitable measures and avoid unintended consequences.
Deliverables
Clear documentation you can act on — and submit if needed.
Current performance, key risks and realistic improvement targets.
Fabric-first measures, junction details, services & ventilation strategy.
Integration of airtightness and ventilation test results, with updated guidance.

Checklist
Email documents or post hard copies — we’ll confirm anything else we need.
Share your drawings and objectives — we’ll map out a practical, PAS 2035-aligned route to better performance.
Where formal schemes or funding require it, PAS 2035 defines roles and a process. We align our advice to whole-house principles so measures are coordinated and risks are managed.
Yes. We can plan a sequence of measures so you get early wins while keeping the whole-house outcome in mind.
Absolutely. We integrate with SAP/EPC work so the paperwork and numbers are consistent end-to-end.
Yes — we’re based in Penzance and serve Cornwall, Devon, Somerset and Dorset.
