Retrofit Strategy

Energy-efficient upgrades for homes with character and future value.

Imagine your Victorian or Edwardian home not only looking beautiful, but feeling effortlessly warm in winter, cool in summer, and quiet all year round. A home that breathes, protects its history, and costs far less to run.

That’s what our Retrofit Strategy is designed to achieve.

We create fabric-first, moisture-safe plans that respect period character while unlocking modern comfort and long-term performance. Using Passivhaus-aligned modelling (PHPP) and decades of site experience, we map a clear pathway from light retrofit upgrades through to deep retrofit (EnerPHit level) — with options for intelligent phasing so you can proceed at the right pace for your family, budget and lifestyle.

What you get

  1. Whole-house assessment — fabric, services, thermal bridges, ventilation.

  2. Performance modelling — PHPP-informed energy and overheating checks.

  3. Moisture-robust detailing — internal insulation, solid walls, breathable systems.

  4. Airtightness strategy — practical sequencing and QA checkpoints.

  5. Ventilation approach — from discreet upgrades to full MVHR, as appropriate.

  6. Phased roadmap — avoid “lock-in” mistakes and plan intelligently.

  7. Indicative costs and carbon impact — to support smart decisions.

  8. Planning & listed-building considerations — heritage-sensitive solutions.

  9. Optional delivery support — technical design, contractor briefs, site QA.

How We Work

  1. Survey & Diagnostics
    We visit your home, capture details, review energy bills, and understand your lifestyle goals.

  2. Options Workshop
    We present light, medium and deep retrofit scenarios — exploring comfort, disruption and cost profiles.

  3. Preferred Plan
    Together, we shape a prioritised, phased retrofit strategy that aligns to your timescales and aspirations.

  4. Delivery Support (Optional)
    From drawings and specifications to contractor briefing and site checks, we can stay involved to protect quality.

FAQs

  • In most period homes, vapour-open, capillary-active systems are safer. They manage moisture and reduce draughts and interstitial condensation risk when detailed correctly.

  • Not always. We test options. For airtight, deeper retrofits, MVHR often delivers comfort, air quality and energy benefits.

  • Yes — your roadmap is designed for intelligent phasing without undoing future steps.

  • Our details aim to retain and celebrate character while upgrading performance.

  • We primarily work in London and nearby boroughs; select projects considered elsewhere.
