Enter your postcode. We'll find your property's current EPC rating and show what upgrades can get you to a B. Relevant if you plan to let out the property — MEES rules tighten to EPC C by 2028.
Frequently Asked Questions
What's MEES and why does the 2028 rule matter?
Minimum Energy Efficiency Standards (MEES) are the legal minimum EPC rating a landlord can let. It's currently E, rising to C by 2028 for new tenancies and 2030 for existing. If you let out a property that won't meet C, you'll either upgrade it or take it off the market. Owner-occupiers aren't directly affected but an EPC below C will hit resale value as the deadline approaches.
How accurate is the cost estimate?
The cost ranges come from Energy Saving Trust 2025 pricing and my own project records. A single survey on your property will tighten the numbers considerably, especially for cavity wall insulation (depends on wall condition) and solar (depends on roof orientation). Get two or three quotes before you commit.
What grants are available?
The Boiler Upgrade Scheme gives £7,500 toward a heat pump. ECO4 covers insulation for lower-income households and Warm Homes Discount recipients. Solar is no longer grant-funded but smart export guarantees (SEG) from your electricity supplier make new installs profitable within 7-10 years.
My postcode has no EPC records. Why?
EPCs are only issued when a property is built, sold, or let. If your home is Victorian and has never sold since EPCs became mandatory (2008), there may not be one. You can commission a domestic EPC survey for £60-120. I can put you in touch with assessors I've worked with.
