With EPC C required on rentals by October 2030, many landlords need to decide whether to upgrade or sell.
Enter the property's current EPC rating, property value, target EPC rating, and your expected hold period. The calculator estimates upgrade costs (based on typical measures for band jumps — cavity wall, loft top-up, heating upgrades, double glazing), projects the rental uplift from a higher EPC band, factors the value impact on sale, and outputs the payback period.
Compares "upgrade and hold" against "sell now at current EPC value". Updated for October 2030 deadline and the £10,000 cost cap per property.
