About the EPC Upgrade Cost Planner

The government has set out a higher energy standard for privately rented homes in England by 1 October 2030, described as similar to EPC C, with a cost cap of £10,000 per property. It is subject to Parliament.

This planner estimates the cost of improvements to bring a rental home up to the target, compares it with the cost cap, and lists the measures from the lowest cost upwards so you can plan the work.
