"If you own a property in London, you have almost certainly thought about your EPC rating in the past twelve months. Mortgage lenders are paying closer attention to energy performance. Tenants are factoring running costs into rental decisions. And with the government signalling stricter minimum EPC thresholds for rented properties, a poor rating is no longer just a line on a certificate - it is a financial liability."
"Yet many homeowners overlook one of the most impactful upgrades available to them: their windows. Heat loss through windows accounts for a significant proportion of a home's total energy waste. Replacing single-glazed or aging double-glazed units with modern, thermally efficient windows can shift an EPC rating by one or even two bands - and that shift translates directly into property value."
"The frame material plays a bigger role than most people realise. Timber is a natural thermal insulator. Unlike aluminium, which conducts heat rapidly and requires a thermal break to perform adequately, a well-engineered timber frame provides insulation as an inherent property of the material itself. This gives timber windows a thermal advantage that shows up directly in U-value calculations - the measure assessors use to determine how much heat passes through a buil"
Mortgage lenders are paying closer attention to energy performance and tenants are factoring running costs into rental decisions. Government signals of stricter minimum EPC thresholds for rented properties turn poor ratings into financial liabilities. Heat loss through windows accounts for a significant proportion of a home's energy waste. Replacing single-glazed or aging double-glazed units with modern double or triple-glazed windows with low-emissivity coatings can raise an EPC by one or two bands and reduce monthly energy bills. Frame material affects thermal performance; timber offers inherent insulation while aluminium requires thermal breaks, influencing U-value calculations.
