Commercial and Domestic EPC

Commercial and Domestic EPC - Commercial and Domestic Energy Performance Certificates. Contact us now on 01323 841488 if you are selling or renting a property in your area and we will provide you with a qualified assessor who will do the assessment for you.


We work on behalf of householders, Estate Agents, Solicitors and Councils throughout the United Kingdom ensuring that EPCs are provided in a timely manner with a quick turnaround.

An Energy Performance Certificate is required on domestic properties before a dwelling is sold or let, and gives prospective buyers or tenants useful information regarding the energy efficiency of the property. A building is given an energy rating on a sliding scale from 'A' to 'G',  with 'A' being the most efficient and 'G' being the least efficient in energy performance. The EPC will also detail what level carbon emissions could be reduced to, by simple energy improvements. An average existing house would expect to gain a 'D' rating but this will be dependent on a number of contributing factors.

The energy rating of a building must be included in any advertising description of the property as of January 2013. This includes publications in newspapers and magazines and on the internet, where the EPC energy rating should be shown as part of the property details.


EPC Ratings


A list of recommendations are outlined in the 'EPC' showing what savings can be made per year if improvements to the property are carried out in accordance with the recommendations. These recommendations are divided up into higher cost and lower cost measures with possible savings that can be made. This will ultimately reduce fuel bills for the householder and increase comfort levels. Examples of this may be to increase the insulation levels in loft spaces, or add heating controls or a new energy efficient boiler. Other recommendations may be to have solar panels fitted or alternative measures such as biomass boilers or ground or air source heat pumps.

All owners and landlords must ensure that an EPC (Energy Performance Certificate) is obtained before the property is marketed for sale or for rent as this is a legal requirement under EU Regulations and an Act of Parliament. The EPC must then be made available to prospective tenants or owners at the earliest opportunity. Failure to produce this information could result with a fine of up to £200 as it is a legal requirement that is enforceable through Trading Standards.

An EPC is valid for a ten year period but can be renewed if an owner or landlord makes improvements to the property that could benefit its marketability.

Government Grants may also be available that warrant the property having an Energy Performance Certificate produced in order to be eligible for funding. This may include ECO and GDHIF.

The energy assessment usually takes up to an hour to complete depending on the size and complexity of the building but we can give you an idea of the expected visit length before sending out the assessor to your premises.

Most Domestic EPCs will be back to you within 24 hours of the EPC visit but we will let you know any reason for delay. One such cause of delay may be that the property is not registered with Landmark so this registration may take a little longer as the report cannot be submitted without a Landmark reference number.

We work for Commercial landlords, management agents and solicitors to carry out Non Domestic EPCs producing  Energy Performance Certificates for commercial and industrial premises.

The EPC will determine the energy efficiency of a building or commercial unit with ratings similar to Domestic properties from 'A' to 'G'  with a rating of 'A' being the most energy efficient to 'G' being the lease efficient. A Commercial EPC can be very useful when making an informed decision before purchasing or leasing premises, so that running cost factors can be considered  and comparisons made with other similar properties. Buyers and potential tenants will be more attracted to properties that are cheaper to run and have the best ratings.

Commercial EPCs have been a requirement since October 2008 as part of EU legislation to help improve energy efficiency in the sector and all buildings must display or have available an Energy Performance Certificate in digital or paper format . Failure to comply with this legal requirement could result in a fine of up to £5000 or 12.5% of the rateable value of the building enforceable by Trading Standards. It is the seller/vendors responsibility to ensure that a certificate is made available before marketing of the property begins whether for sale or for lease. Marketing literature must include the EPC rating of the property being advertised.

As there is a vast array of different property types in the commercial and industrial sector, each property type must be considered carefully before we can give you a quote due to the number of variables involved in assessment procedures. Property types can include offices, factories, retail units, industrial type buildings, mid terrace shops or supermarkets, warehouses, hotels, guest houses and other non domestic dwellings.

For instance we have to consider the type of property, size in square meters or feet, number of storeys, if the premises is detached or adjoined, building age, average ceiling heights, wall and roof construction, wall and loft insulation, alternative wall construction, windows if double or single glazed including their age, heating system with the fuel type making a considerable difference to the rating. Also other variables such as the boiler type, types of lighting being used, hot water system, air conditioning and solar photovoltaic or solar thermal  improvements. All this information goes into calculating the energy rating of your commercial building.

The complexity of the work will determine what type of assessment is required. This is broken down into three levels. Level 3 which is the majority of small and medium sized buildings using low energy heating and cooling systems. Level 4 where the heating system is over 100kw and the cooling system is greater than 12 kw. Level 5 which covers buildings over 10,000 m² or small buildings that may have complex service systems or features such as curved fascias or with atriums.

The amount of time it takes to do the energy assessment will depend on the size and complexity of the building, but we will give you a rough idea of this before we arrange the EPC visit with you.

Floor plans of the property will be needed in most cases, if they are available, to help us give you a better quote. If this can be emailed in a digital format with elevations, construction details and with the building services included.

The EPC report will be carried out by a fully qualified non-domestic energy assessor who will be an accredited member of an approved Government accreditation scheme, fully insured and CRB disclosure checked. The EPC report is also accompanied by a recommendation report which shows how the building can be improved to offer greater energy efficiency.  Any improvement will be listed with likely associated cost and payback period.

The energy assessor will make site notes, take photographs, draw floor plans if necessary by doing measurements of external and internal zones using the correct methodology and use the evidence collected as data entry for the Simplified Building Energy Model (SBEM) software that will produce the EPC rating and recommendations. Assessors are regularly audited by their accreditation bodies to ensure the correct procedures and conventions are being carried out.

There are some types of commercial building that do not require and EPC, which we will let you know before giving you a quote. These include detached properties with low energy demand that are less than 50m², properties that are being demolished and places of worship. Also temporary structures with a planned use less than 2 years and low energy demand properties such as agricultural barns.

The commercial energy assessor (Non-Domestic Energy Assessor NDEA) will ensure that the correct level of assessment is carried out and produce the certificate in the fastest possible time. The EPC is usually sent within 48 hours of the EPC visit but this will depend on the variables encountered. The Commercial EPC is then registered with Landmark, which is the central register for all lodged reports. We will send you the completed report by email. Payment must be made in advance of the certificate being issued. We will therefore send you an invoice for immediate payment to ensure that a delay is not encountered.
