Overview

Commissioned under SHDF Wave 1 for the principal contractor in Nuneaton (West Midlands), Crawford & Co completed 184 retrofit assessments and coordinated the retrofit of 167 homes.

Approach: our assessors surveyed each property — insulation, heating, ventilation and potential for renewables — and, drawing on resident interviews, produced detailed reports prioritising cost-effectiveness and carbon impact. The coordination phase turned these into a deliverable PAS 2035 strategy: measure planning, scheduling, budgeting, procurement and close stakeholder liaison.

Outcome: a compliant, whole-house programme delivered at pace across 167 homes, improving energy efficiency and cutting carbon while keeping disruption to residents to a minimum.

Strategy

Fabric

Wave 1 stock was predominantly system-built and cavity construction. Pre-existing defects are the rule rather than the exception on this kind of stock: dampness, condensation and mould, cavity wall tie failure, roof slumping and spread, timber decay and lintel failure. Every one of those has to be resolved before insulation goes on. Identifying them at assessment is what makes enabling works a planned item rather than a mid-programme surprise. Fabric measures were then specified per property — loft, room-in-roof and flat-roof insulation, cavity or external wall insulation, underfloor insulation, and replacement windows and doors — rather than issued as a standard package.

Service

Ventilation is designed alongside airtightness, not after it. Sealing a home without addressing how it breathes moves a moisture problem rather than solving it, so extract ventilation forms part of the same specification as the fabric work. Heating and hot water measures are matched to the demand the fabric measures leave behind, so that plant is sized for the improved home rather than the original one.

Renewables

Where a property suits it, solar PV is added after the fabric measures, so that generation offsets a demand already reduced rather than masking one that has not been. Roof orientation, structural capacity and the condition of the existing covering all decide suitability, and the assessment records that rather than assuming it.

Vital Statistics

Properties in scope: 184 assessed, 167 retrofitted. Crawford & Co scope: Retrofit Assessment, Retrofit Coordination. Programme period: 2022 to 2023 (indicative). Each assessment records the property’s construction and its modelled performance before and after the proposed measures — space-heating demand in kWh/m² per year, carbon in kg per year and estimated energy cost. Figures are held per property rather than averaged, and are available to the client in full.

Detailing

The main technical risk on Wave 1 was installer familiarity with PAS 2030. An experienced coordination team is what catches paperwork discrepancies early and feeds them back before they become compliance problems at lodgement. Our retrofit condition report was developed in house and approved by both the scheme provider and TrustMark. The work behind it contributed to our managing director’s appointment to the BS 40104 steering group — the British Standard for retrofit assessment. Where PAS 2035 leaves a technical question genuinely open, we take it up with the standard’s authors rather than guess.

Comfort

The measure of this work is a home that is warmer, drier and more affordable to run, and that stays that way. Lower heat demand is only part of it — even temperatures, humidity that stays under control and plant that runs quietly all decide whether a resident actually feels the difference. Residents live in these homes throughout. Capturing everything needed in a single assessment visit exists for exactly that reason.

Monitoring

Coordinators quality-check every assessment before it reaches design, and the scheme runs with a live view shared between client, designer and installers so that discrepancies surface in days rather than at handover. Regular review meetings with client, designer and installers run for its duration. Post-completion documentation is prepared for TrustMark lodgement through secure data sharing.
