Figures are VAT-inclusive planning allowances unless a later supplier quote lists VAT separately. Ranges use Pocketa's internal UK planning assumptions, not a live market-price feed. London and other expensive areas may sit higher. Planning bands last updated 28 June 2026 (version uk_planning_v1). Any confidence label on the result is a planning judgement from your answers, not a scientific measure or guarantee.
