We Are Commercial and Domestic Energy Assessors and Auditors.

We Are Suppliers Of:

ESOS compliant reports

ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. 

Commercial EPC’s

Commercial buildings in the UK require an Energy Performance Certificate when they are constructed, sold or let. They are valid for 10 years. 

Domestic EPC’s

A domestic EPC gives a property an energy efficiency rating from A (most efficient) to G (least efficient) and is valid for 10 years. You must have one before you market your property to sell or rent. 

Display Energy Certificates

Display Energy Certificates (DECs) are designed to show the energy performance of public buildings. 

ESOS (Energy Savings Opportunity Scheme)

Additional Information

It is a mandatory government scheme which affects up to 10,000 UK organisations. The scheme has been designed to increase industry’s awareness of energy consumption and to make it easier for businesses to take action, to lower their energy bills and lower the rate of carbon emissions across the UK.   

The ethos behind the scheme is that reducing your energy consumption goes hand in hand with saving you money, so that the costs of the ESOS audit itself are more than paid back, if the identified energy saving measures are implemented. 


Who does ESOS apply to?

ESOS will apply to your company if it has more than 250 employees or an annual turnover exceeding 50 m Euros (£38,937,777) and a balance sheet exceeding 43 m Euros (£33,486, 469). 

For UK incorporate groups if any part of the group qualifies for ESOS, then the whole group must comply. These large companies are now required to produce detailed reports on their energy use every four years. The qualification date and compliance date for each phase are provided below, as you can see we are now in Phase 2 of ESOS.

Phase | Qualification Date | 4 Year Compliance Phase | Compliance Date

Phase 1 |  31st December 2014  | 6th December 2011 - 5th December 2015 | 5th December 2015

Phase 2 |  31st December 2018 | 6th December 2015  -  5th December 2019 | 5th December 2019 

Phase 3 | 31st December 2022  |  6th December 2019  -  5th December 2023  |  5th December 2023  

By appointing a lead assessor, you will be guided through the ESOS process as they are required to sign off your compliance before submitting notification to the Environment Agency. The compliance deadline for Phase 3 is the 5th December 2023.

Display Energy Certificates

Additional Information

These show the actual energy use of a building, the Operational Rating, and help the public see the energy efficiency of a building. A DEC is always accompanied by an Advisory Report that lists cost effective measures to improve the energy rating of the building.

If your building is more than 1000m² then the DEC is only valid for 1 year whilst the advisory report is valid for 7 years.  If your building is between 250m² and 1000m² then both the DEC and advisory report is valid for 10 years.     


DECs are mandatory requirements for buildings with a total floor area over 250m2 which are occupied by a public authority or institution and provide a public service. Despite this, many private sector organisations such as retail units and offices are having Display Energy Certificates produced to demonstrate corporate responsibility on green issues but, most importantly, in order to improve their energy efficiency in order to Save Energy, Cut Carbon and Save Money! 


If you do not have a DEC on display your local authority can issue a penalty notice of £500.00. It is law that any public building must show a valid DEC at all times in a location which is clearly visible to the public. You could also be penalised £1000.00 for failing to possess or hand your local authorities our advisory report.

Commercial Energy Performance Certificates

Additional Information

Most non-residential buildings when built, leased or sold require an EPC (Energy Performance Certificate) before marketing or letting can commence to meet the Energy Performance of Buildings Directive which must be produced by an accredited Energy Assessor.

The certificate shows the energy rating of a building. It indicates the energy efficiency of the building fabrics and the heating, ventilation, cooling and lighting systems.


The EPC is calculated by analysing a number of physical attributes the property has such as:


  • The property’s size and age
  • Type of construction materials used
  • Its lighting and ventilation
  • Any wall or loft Insulation
  • The condition of its windows
  • Central heating and hot water systems

The Recommendation Report list recommendations selected by the energy assessor for the improvement of the energy performance of the building. The recommendations are listed four headings: short payback, medium payback, long payback, and other measures. Save Energy, Cut Carbon and Save Money!

If you don't have an EPC you will be penalised. The penalties for commercial properties is based on the rateable value of the property up to a maximum cap of £150,000.

Domestic Energy Performance Certificates

Additional Information

Any domestic property leased, rented or sold will require an EPC before marketing or letting can commence which can only be completed by an accredited Energy Assessor.

The home’s performance is rated in terms of the energy use per square metre of floor area, energy efficiency based on fuel costs and environmental impact based on carbon dioxide (CO2) emissions. A property’s rating will depend on its:


  • Age
  • Location
  • Size
  • General condition
  • Wall and loft insulation
  • Heating and hot water systems
  • Ventilation
  • Electricity / Lighting
  • Presence of any energy generation such as solar panels

Please note: the property’s rating does not take into consideration any home appliances. 

Accredited energy assessors produce EPCs alongside an associated report which suggests improvements to make a building more energy efficient. Save Energy, Cut Carbon and Save Money!

The maximum financial penalty for non-compliance in residential properties is £5,000.

Renewable Energies

From the end of 2004, worldwide renewable energy capacity has grown 10–60% annually for many technologies and in 2015 global investment in renewable energies rose 5% to $285.9 billion, breaking the previous record of $278.5 billion in 2011. In the same year, renewables, excluding large hydro, accounted for the majority of all new power capacity (134 GW, making up 53.6% of the total capacity) worldwide.  Thanks to growing investment from both the private and public sector, technological advancement, mass production and market competition renewable energy technologies are getting cheaper. A 2018 report from the International Renewable Energy Agency (IRENA), found that the cost of renewable energy is falling rapidly and will likely be equal to or less than the cost non-renewable energy sources such as fossil fuels by 2020.

At Southernhay Living we are experts on renewable technologies and regularly advise on solar thermal-solar water heater panels, solar electricity-photovoltaic (PV) panels, biomass, ground source heat pumps, air source heat pumps, wind turbines and hydro-water turbines. 

So if you’re a company or private individual wanting to Save Energy, Cut Carbon and, most importantly, Save Money get in touch today and see how our trained assessors can help you.

advice on complying with MEES (Minimum Energy Efficiency Standards) both Commercial & Domestic

The Minimum Energy Efficiency Standard (MEES) which came into force in England and Wales on 1 April 2018, applies to private rented residential and non-domestic property and is aimed at encouraging landlords and property owners to improve the energy efficiency of their properties 

Energy Advice on Net Zero Carbon Buildings

Net zero carbon is when the amount of carbon dioxide emissions released on an annual basis is zero or negative. Hence, a net zero carbon building is a highly energy efficient building which is fully powered from on-site and/or off-site renewable energy sources and offsets.
