Case Studies

See how retrofit compliance projects come together — from room-in-roof conversions to cavity, internal, and external wall insulation. Each case study walks through the challenge, the solution, and the outcomes a typical UK home can expect.

These case studies are representative examples based on typical project delivery and are not claims of specific client projects.

1

Case Study

Room-in-Roof Conversion

Project: Loft Room-in-Roof Conversion Property: Semi-detached home Location: Manchester Purpose: Additional bedroom / living space

Challenge

The property had an unused loft with poor insulation, limited lighting, and no proper access or services, making it unsuitable for living use.

Solution

A room-in-roof conversion was planned including structural strengthening, staircase installation, roof windows, insulation upgrades, electrical and heating extension, and full Building Regulations compliance.

Typical Outcome

The loft space was transformed into a usable, comfortable room suitable for a bedroom, office, or study with improved lighting, insulation, and overall functionality.

Benefits

  • Extra living space without extension
  • Improved thermal comfort
  • Better natural lighting
  • Increased property usability

This is an illustrative example based on typical UK loft conversion projects and does not represent a specific client case.

Case Study

Cavity Wall Insulation Upgrade

Project: Energy Efficiency Retrofit Property: 1960s Semi-Detached Home Location: Manchester

Challenge

High heating costs and noticeable heat loss through external walls.


Approach

  1. Endoscopic cavity inspection
  2. Suitability testing for cavity width and moisture condition
  3. Installation of mineral wool bead insulation
  4. Post-installation thermal imaging verification
  5. CIGA guarantee registration for long-term protection (where applicable)

Outcome (Typical Result)

  • Reduced heat loss through external walls
  • Improved indoor thermal comfort
  • Lower annual heating demand
  • Enhanced EPC performance potential

Status: representative retrofit scenario — based on typical project delivery, not a specific client case.

Case Study

Internal Wall Insulation (IWI)

Project: Solid Wall Insulation Upgrade Property: Pre-1930s Terraced House Location: Manchester

Challenge

The property had solid brick walls causing high heat loss, cold rooms, and condensation issues.

Solution

Internal Wall Insulation was installed using insulated plasterboards with vapour control layers, along with thermal bridge detailing around windows and junctions.

Outcome (Typical Result)

  • Reduced heat loss through external walls
  • Improved indoor comfort and warmth
  • Lower energy consumption
  • Reduced condensation risk (with proper ventilation)

This is an illustrative example based on typical UK retrofit projects, not a specific client case.

Case Study

External Wall Insulation (EWI)

Project: External Wall Insulation Upgrade Property: Solid Wall Semi-Detached Home Location: Manchester Purpose: Improve energy efficiency and reduce heat loss

Challenge

The property had uninsulated solid external walls, leading to high heat loss, cold internal surfaces, and increased energy bills. The façade also showed signs of poor thermal performance and condensation issues.

Solution

An External Wall Insulation system was designed and applied, including insulation board installation, reinforcing mesh, base coat render, and weather-resistant decorative finish. Window and door reveals were also insulated to reduce thermal bridging.

Typical Outcome

The property would typically experience significantly improved thermal performance, with reduced heat loss through external walls and enhanced indoor comfort throughout the year.

Benefits

  • Lower heating costs
  • Improved EPC rating potential
  • Better thermal comfort
  • Enhanced exterior appearance
  • Reduced condensation risk

This is a representative example based on typical project delivery and is not a claim of a specific client project.
