EPC Guides & FAQs
Everything you need to know about Energy Performance Certificates, from understanding ratings to improving your property's efficiency
Frequently Asked Questions
What is an EPC (Energy Performance Certificate)?
An Energy Performance Certificate (EPC) is a document that shows how energy efficient a property is. It rates properties from A (most efficient) to G (least efficient) and provides recommendations for improving energy efficiency. EPCs are legally required when selling or renting properties in the UK.
How long is an EPC valid for?
EPCs are valid for 10 years from the date of issue. However, if you make significant improvements to your property's energy efficiency, you may want to get a new assessment to reflect the better rating.
Do I need an EPC when selling my house?
Yes, an EPC is legally required when selling a property in the UK. You must have a valid EPC before marketing your property, and it must be available to potential buyers. Failure to provide an EPC can result in fines of up to £5,000.
Do I need an EPC when renting out my property?
Yes, landlords must provide a valid EPC to tenants before they move in. The EPC must be rated E or above for new tenancies from April 2020, and for all existing tenancies from April 2023. Properties rated F or G cannot be rented out without improvements.
How much does an EPC assessment cost?
EPC assessments typically cost between £60-120, depending on the size and type of property. The cost may vary by location and assessor. It's worth getting quotes from several accredited assessors in your area.
How long does an EPC assessment take?
A typical EPC assessment takes 1-2 hours for most residential properties. The assessor will need to inspect all rooms, measure the property, check heating systems, insulation, and other energy-related features. Larger or more complex properties may take longer.
What does the EPC assessor look at?
EPC assessors examine: wall, roof, and floor insulation; heating systems and controls; hot water systems; lighting; windows and doors; ventilation; and any renewable energy systems. They'll also measure room dimensions and check for any energy-saving features.
Can I improve my EPC rating?
Yes, there are many ways to improve your EPC rating: installing loft and cavity wall insulation, upgrading to a more efficient boiler, fitting double glazing, adding renewable energy systems like solar panels, and improving heating controls. The EPC report will provide specific recommendations.
What's the difference between domestic and non-domestic EPCs?
Domestic EPCs are for residential properties (houses, flats, apartments). Non-domestic EPCs are for commercial properties (offices, shops, industrial buildings). They use different assessment methods and rating scales, but both provide energy efficiency ratings and improvement recommendations.
How do I find an accredited EPC assessor?
You can find accredited EPC assessors through our directory. All assessors must be accredited by government-approved schemes like Elmhurst Energy, Stroma, or Quidos. Look for assessors with good reviews and competitive pricing in your area.
What happens if my property gets a low EPC rating?
A low EPC rating (F or G) doesn't prevent you from selling or renting, but it may affect the property's value and appeal. For rental properties, you'll need to make improvements to reach at least an E rating. The EPC report will suggest cost-effective improvements to boost your rating.
Are there any exemptions from EPC requirements?
Yes, some properties are exempt from EPC requirements: listed buildings where compliance would unacceptably alter their character, temporary buildings with planned use of less than 2 years, stand-alone buildings with total useful floor area of less than 50m², and certain industrial sites.
