The second phase of the Energy Savings Opportunity Scheme (ESOS) is now underway. ESOS requires all large businesses to produce reports on energy usage and efficiency every four years. ESOS is a mandatory government scheme which affects up to 10,000 organisations in the UK.
The scheme has been designed to increase awareness of energy consumption to make it easier for businesses to act, to lower their energy bills and lower the rate of carbon emissions across the UK.

Who is affected?

ESOS applies to organisations for which one or more of the following criteria apply:

  • Employ 250 or more people

  • Has an annual turnover in excess of £38,937,777 and a balance sheet total in excess of £33,486,489

  • Is part of a group of UK organisations that includes at least one eligible organisation.

What you need to do:

Organisations that qualify for ESOS must carry out ESOS assessments every four years.

These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.

There are threats of large fines for non-compliance.

Client Feedback


“The Carbon Trust survey report carried out by Raven Energy enabled us to achieve significant reductions in energy consumption. We have with the help of Keith’s advice reduced out retail lighting wattage from 75watt’s per sq. metre down to 50watt per sq. metre. The company has also started an energy steering group across the whole of the Next business to drive the energy saving action recommended throughout the business.”


Our Projects

Helping Businesses Blossom

Boots Full Energy Reduction Design Project

An Innovative Solution

In 1994 Keith Raven developed and designed a lighting conversion solution for Boots the Chemist that was implemented in 120 of Boots largest stores, and was also implemented in all Boots future stores.

The scheme saved £1 million pounds per year in reduced energy consumption.

The scheme was also the first retail store to utilise fluorescent dimming for different trade periods and for restocking after hours when the lighting level was reduced by around 20% of the full lighting level.

The scheme obtained national recognition at the Electrical Review Industry awards winning a commendation for environmental action.

Restaurant Group project 

A Story of Success

Raven Energy were approached by the Restaurant Group to come up with ways of lowering their running costs.

Our surveys identified large savings in various areas but the highest were in new lighting designs. 

• New energy efficient lighting systems in 195 restaurants nationwide
• Average payback 1.6 years
• All paybacks include survey, design installation and equipment costs
• Significant reduction in required lamp replacements (average lamp life 3 years)

Roadchef Energy Reports

Energy Surveys

Raven Energy Consultancy was appointed in August 2014 to produce guidance to improve the sites energy efficiency prioritising on lighting improvements to reduce consumption, lower their maintenance costs and enhance their brand lighting ambiance.

The services at Watford Gap and Northampton were selected to act as a trial for the scheme. Detailed surveys were carried out by Raven Energy of all the existing luminaires in the front of house and rear areas of the premises.

New lighting designs were produced for all areas reviewing the existing layouts standards and the requirement of new control associated with occupancy and daylight levels.

Selected circuit monitoring equipment was fitted where practical to enable proof monitoring of before and after implementation energy consumption data.

The installation which involved many LED luminaire/control options of the new design was installed by Raven Electrical Contractors Ltd.

The energy saving results of the trial exceeded expectations as follows:-

  • The excellent business of paying back the capital expenditure in a short time period as well as improving the lighting ambience convinced Roadchef to roll out the scheme throughout the Roadchef estate.

  • In preparation a selection of Roadchef sites were surveyed by The Raven Group to enable the new energy efficient design to be further rolled out.

  • At Northampton a further opportunity was identified by Raven Energy in which the external lighting of the schemes to be converted to accept the latest 3rd generation LED technology by fitting a proprietary LED KIT to the existing high pressure sodium luminaire post heads.

  • In 2015 6 Roadchef motorway services sites were fitted out internally and 4 outside lighting LED projects were completed by Raven Energy Contractors Ltd.

  • The projects carried out in 2015 reduced annual consumption from 3,400,000Kwh to 820,000 Kwh this was a reduction in lighting consumption of 76%. The project provided a reduction in Carbon of 1,370 tonnes of CO², paid back in less than 2 years with savings for Roadchef of £260,000 annually.
