​

What is an Energy Performance Certificate (EPC)?

​

Energy Performance Certificates (EPCs) are a legal document displaying an energy efficiency assessment of a dwelling or commercial unit. The certificate visually displays the rating from A – G also in Green to red, depending on how energy efficient the property is. This is like new electrical appliances, displayed in a similar fashion.

It is assumed the better the rating, the lower the energy usage…. The rating considers the heating, lighting, and hot water -assumed usage.

​

How long is an EPC valid for?

​

An EPC is valid for 10 Years

​

When is an EPC needed?

​

By law EPC is required when a building is constructed, sold, or rented. EPC are also required for the renewable heat incentive and the feed in tariff.

​

Is a commercial property exempt from having an EPC?

​

EPC are not required for.

  • Places of Worship

  • Temporary buildings with less than 2 years in situ

  • Detached (standalone) buildings with a total floor area of 50m2 or less. Commercial only.

 

Are EPC assessors qualified and how do I check?

 

  • EPC's can only be completed by a qualified /registered Assessor. The Assessors accreditation details can also be checked on the Landmark official register; Get a New Energy Certificate

 

 

How will I receive my EPC?

 

 

I have had my report; why does it say, 'Insulation Assumed'?

 

  • The assessor will gather the required data which will include evidence to support his /her conclusions If the stakeholder has any other supporting evidence, we ask this be made readily available prior to the site visit or while in the property. As this is a nonintrusive survey the assessor is limited to observations.

  • If no evidence is available, the assessor may have to default the insulation based on age of the property and building regulations at the time of construction.

 

When do I get the report?

​

The report is emailed within 24 hours after the Survey and when payment is received.

​

What does the EPC say about the property?

​

EPC’s gives simulated information about the energy performance of a property; this will include recommendation as to how to improve the energy efficiency of all properties surveyed.

​

How long does it take to perform an EPC assessment?

​

Domestic EPC’s take from 30 minutes to one hours depending on size. Commercial EPC’s can take from 1 hour to 2 days depending on the size. The assessor will not cause any inconvenience and the site survey is nonintrusive.

What is an energy assessor looking for?

​

  • Construction of the building fabric, walls, roof floors and any relevant insulation.

  • Glazing type and percentage.

  • Number of open fireplaces.

  • Checking the make and model of the boiler include the efficiency under EU SEDBUK regulations.

  • Looking for renewable or low carbon technology e.g. solar panels, air source heat pumps.

  • Total amount of low energy light bulbs.

  • Ascertaining the type of heating system in situ Elec, Gas Boiler to radiators, air source heat pump etc.

  • Domestic Hot water type, e.g. from Combination (combi) Boiler, cylinder and insulation measures etc.

  • Calculating the exposed heat loss walls.

  • Checking for excessive window area, larger than typical.

  • Conservatory’s types, if its heated and or separated.

  • Extensions, age and building control sign off.

  • Total amount of habitable rooms.

​

How long till I receive the report?

​

Residential Reports are usually emailed within 24 hours after the site survey, but only when payment is received. Larger Commercial buildings will take longer to send.

​

What is the Minimum energy efficiency standards?

​

  • Currently properties with a new or lease extension must achieve an EPC rating of E or above to be legally rented.

  • This will change in April 2023 when all leased properties with an existing lease must achieved an E or above.

  • The government is looking at reduce the rating to a C in 2027 and a B in 2030 however this has not been confirmed. They are also suggesting that all private rented properties must have a valid EPC by 2025.
