About This Property

This terraced flat is located in CARMARTHEN, SA31 3LE. The property offers 75m² (807 sq ft) of modest-sized living space with 5 habitable rooms. It is a post-war property from the mid-20th century.

The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The walls feature cavity wall insulation with good efficiency ratings, providing solid thermal performance. The pitched roof lacks adequate insulation. Topping up loft insulation to 270mm (the recommended depth) typically costs £300-£500 and could save £150-£250 annually, with the investment often paying for itself within 2-3 years.

For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
