For homeowners in Clare, you typically won't need planning permission to replace existing security locks or doors if the new ones are of a similar style and size. However, if your property is a listed building in Clare or located within a designated conservation area, you absolutely must consult with Clare County Council's planning department before any work commences. Significant alterations, such as changing a window opening into a new doorway, will also require planning approval.
Regarding grants, direct schemes specifically for locksmith security upgrades are limited. The SEAI offers grants primarily for energy efficiency upgrades, which can include new, energy-efficient doors and windows, but this is not focused on the security aspect directly. Clare County Council also provides certain housing aid grants, but these are generally for specific needs of older people or those with disabilities, rather than general security improvements for all homeowners.
