About EPC Advisor
Making EPC data accessible and actionable for UK homeowners and landlords.
Who We Are
EPC Advisor is operated by Zanzero Ltd. Our mission is to make Energy Performance Certificate data accessible and actionable for UK homeowners and landlords, helping you understand your property's energy efficiency and take informed steps to improve it.
What We Do
We provide a free EPC lookup service covering over 25 million properties across England and Wales. Beyond simple certificate lookups, we offer personalised improvement guides, regulatory guidance for landlords, and insights into energy efficiency trends across the country.
Our Data Sources
All property data comes from the official DLUHC (Department for Levelling Up, Housing and Communities) EPC register, accessed via data.gov.uk. This data is published under the Open Government Licence v3.0.
Editorial Approach
Our content is based on official government data and industry guidance. We review and update our guides regularly to reflect the latest regulatory changes, improvement technologies, and best practices. Our recommendations are generated algorithmically from official EPC assessment data.
Independence Statement
EPC Advisor is an independent service. We are not affiliated with, endorsed by, or connected to DLUHC, GOV.UK, or the official EPC Register. We use publicly available government data under the Open Government Licence. Our recommendations and analysis are our own and do not represent government advice.
