    What is retrofit?

    Retrofitting is the act of fitting to existing buildings new systems designed for high energy efficiency and low energy consumption. This can range from small DIY activities such as fitting energy-efficient light bulbs to installing state-of-the-art heating systems. The reasons for doing this are simple – a more efficient building will be cheaper to run, have a lower impact on the environment and the higher energy rating that comes with this can increase the value of the property.

    We provide professional Retrofit Assessments across Devon and the South West, a formal assessment used as preparation for larger energy upgrades such as insulation, ventilation improvements or heating system changes.

    The retrofit assessment is a detailed review of your property to make sure improvement works are:

    • Suitable for the building
    • Technically sound
    • Properly sequenced
    • Compliant with current standards

    The assessment includes an energy survey (EPC data), condition report and occupancy review. It ensures your home is treated as a whole system, reducing the risk of later damp, ventilation problems or unintended issues.

    If you are a landlord aiming to improve an EPC rating, a homeowner planning upgrades, or an installer needing compliance sign-off, we provide clear, practical reporting to move your project forward.

    Background Ventilation Testing

    TargetCO2 provides both air tightness testing and ventilation testing services across Devon and the South West.

    Background ventilation testing for existing homes measures airflow through trickle vents, wall vents and other permanent ventilators to confirm adequate background ventilation provision.

    This service is typically required where there are:

    • Damp or mould concerns
    • Insulation upgrades
    • Retrofit compliance requirements
    • Landlord property reviews

    It focuses on measured airflow performance within occupied properties, ensuring ventilation levels are appropriate for the size and layout of the dwelling.New build air tightness (air permeability) testing is a separate compliance service, which we also provide.

    Everything was explained in plain English and we passed first time. The whole process was much easier than I’d anticipated."

    Self-build client, Truro

    "We needed a single new build tested at short notice. TargetCO2 gave us clear prep advice, came out when they said they would and the certificate was with Building Control the next day. We’ll be using them on all our future plots."
