Percentage increase = (highest share / lowest non-zero share - 1) x 100. Calculated before rounding. EPC comparisons exclude shares displayed as 0.0% and use postcode districts with at least 100 valid records for each signal. Historical property signals guide investigation; they do not establish current purchase intent.
Why local context matters
Replacement windows and doors in Gwynedd need messages suited to the properties and customers you serve. The retained owner-occupied EPC cohort contains 23,639 properties across 31 named postcode districts. Use the recorded glazing signals to select questions and geographic tests, then validate them with your enquiries.
Explore your offer alongside local property characteristics, customer enquiries and the wider area context. Treat product-fit ideas as hypotheses to validate with your company’s evidence.
Property figures use the current Welsh administrative area. Local Google Ads comparisons are not included because a matching county targeting geography has not been independently validated. Property analysis uses dated ONS UPRN membership in the specified current administrative area. Location source

Two offers to test with owner-occupiers
Standard replacement offer
Test practical messages about replacement double glazing, uPVC windows and doors, and composite-door options, with clear installation and quotation information.
Premium design offer
Test aluminium windows, bespoke finishes and higher-specification door options. Investigate heritage and conservation requirements before proposing changes.
These are marketing offer segments, not classifications of household wealth or material preference. Both offers need company-specific enquiry and conversion validation. EPC window signals do not establish door condition.
