    Hi all
    We have a detached Dormer bungalow built 25 years ago and are looking at having the cavity pumped with bead insulation. As my Wife and I are both OAP and money is tight we looked at what grant aid is available to help. I have been advised that to avail of any heating grant that our rooms must have an external air vent. I cannot find confirmation of this online and wonder if this is indeed a requirement. Thanks in advance.

    Yes. Per post above - fresh air is hugely important for a variety of reasons, primarily to maintain your health. Poor ventilation has negative implications for spread of airborne viruses e.g. Coronaviruses.

    Poor ventilation potentially leads to damp and mould, too. Ventilation of gasses in the home, e.g. carbon monoxide, is vital. Don't skimp on the ventilation.

    Technical Guidance Documents Part F will help you understand the requirements.

    Don't skimp on ventilation.

    Having the wall pumped (grant aided or not) may not yield you much bang for your (oap) buck in terms of reduction in heat loss because dormers are notorious for heat loss through excessive air leakage and pumping the cavity does not address this. You might be better to start with an air tightness test or a more comprehensive heat loss survey.

    Is this idea part of a wider strategy or what?

    Having lived in a dormer for 25 years, I know exactly what the previous poster is pointing to.
