We also offer compliance services for ESOS PHASE 2, ISO 50001 and P272 to compliment our energy portfolio.
Please select a service below for more information.
Under ESOS large UK organisations were obligated to carry out ESOS energy assessments before the deadline of 5th December 2015, once completed assessments will be repeated once every 4 years.
If an organisation has an accredited ISO 50001 certificate that covers the full scope of ESOS, then that will suffice as ESOS compliance. All organisations need to do then, is notify the EA and provide proof of compliance via that route.
However, if ISO 50001 is not used as a route to compliance, then an ESOS energy audit will be needed as the next best and most common available route to compliance.
Every four years, a new compliance period starts.
The qualification date for compliance Period 2 is 31st December 2018, with proof of compliance covering the period (from 6 December 2015 to 5 December 2019) being required by 5 December 2019.
If your organisation chose an ESOS energy audit as the compliance route for Period 1 then you will now have a robust ESOS evidence pack that will include:
However, you won’t be able to use this information to demonstrate Period 2 compliance, so this exercise will need to be repeated in four years’ time.
Alternatively, information from your first ESOS energy audit can be used as the basis for implementing an energy management system (EnMS) to allow realisation of the energy saving opportunities.
If your system is then certified to ISO 50001 during the next four years, your organisation will automatically demonstrate Period 2 ESOS compliance.
Benefits of implementing ISO 50001 to demonstrate Period 2 compliance

Communication networks are used extensively in Building Automation systems at the automation and management levels, but are less used at the device (sensor or meter) level. PSW Energy Control changes this situation. Our system significantly simplifies the site level wiring, but without increasing material cost. Furthermore it reduces commissioning time and offers the possibility to integrate existing HVAC and lighting controls.
Our approach provides a flexible, modular system that can easily be expanded by simply extending a 2-wire Dupline network bus cable and adding the desired modules. The system provides flexibility, backwards compatibility and expandability whilst saving costs. Last minute changes are easily accommodated. Easy handling, easy design, planning, installation and commissioning are inherent features of the network.
Electrical Demand Control – In addition to the regular usage rate, most utility companies impose a demand charge. This is an extra charge per kilowatt based on the highest rate of use for a given period (usually 15 minutes). The demand charge can amount to as much as half the utility bill. DDC programs limit the demand charge in a number of different ways:
Duty cycling – This turns off different HVAC units during peak load times in order to reduce the demand charge. The system regulates off time according to such things as indoor temperature.
Load shedding – This turns off various building electrical loads to reduce demand charges. Usually a schedule called a shed table is developed that sets priorities on which loads will be first to be turned off.
Averaging control – This averages the input from several sensors. For example, building temperatures will vary in a building. The temperature in a lobby will be much different than the temperature of an inner office on one of the higher floors. The computer receives input from sensors located in different parts of the building, averages them, and acts on the average.
Soft starting – This brings large equipment on line slowly to minimize the large onrush of current that occurs when starting large motors.
Event scheduling – In addition to the ordinary schedule for a buildings occupied times, our Smarter Buildings system can control many different time schedules:
Temporary scheduling – A timed override switch can be used for areas that have variable schedules. Monthly or weekly events can be programmed.
Economizer Control – Economizer control sets the system to use outside air instead of the mechanical chiller to cool the building, when outside air temperature and humidity are within a specified range.
Sequence Control – Sequence control, also called lead/lag control, is used if two or more pieces of the same item of equipment (such as pumps, chillers, or compressors) are installed in a system. Sequence control puts one in operation if the other fails. For example, if there is a primary pump and a backup pump, if the primary pump fails, the backup is started. Another strategy is to alternate the use of the two pumps so that they receive equal wear.
Reset Control – Reset control is an energy-saving strategy that changes the set point of a controlled variable as another variable changes. For example, a typical hot water set point for a heating coil is 220ºF when the outside air is at 0º. When the outside air temperature reaches 60º, the hot water set point could be automatically reduced to 140º, because less energy is needed to maintain the air temperature.
Low Limit and High Limit Control – Low limit and high limit control adjusts the system to limit the low and high of a controlled variable. For example, if the outside air temperature drops very low, the system adjusts to prevent the mixed air temperature from dropping below a certain set point.

An effective energy management approach requires and understanding of energy costs, bench-marking and energy performance. This includes matching energy use to requirements and maximising system efficiencies. Energy consumption during construction can vary depending on the various stages, equipment and plant in use at the time, their state of repair and the amount and type of electrical equipment installed on fixed assets. The fundamental goal of construction energy management is to build with the least cost and least environmental effect. The judicious and effective use of energy to maximise profits (minimise costs) and enhance competitive position underpins this strategy. Accurate monitoring minimises energy costs / waste without affecting the construction programme or build quality.
The environment will benefit from reductions in energy use and carbon emissions which will improve the company image. As most areas of a construction sites have no energy monitoring capability and energy consumption is based on supplier data which can be flawed and prone to error. This highlights the importance of, providing energy usage reports for cost reduction and compliance, not to be a burden on administration and back-office functions, utilising supplier energy usage data for verification and to target energy or cost reduction and providing detailed assessment of sub-contractor energy related performance.
Using energy efficiently helps organizations save money as well as helping to conserve resources and tackle climate change. ISO 50001 supports organisations in all sectors to use energy more efficiently, through the development of an energy management system (EnMS). The ISO 50001 is based on the management system model of continual improvement also used for other well-known standards such as ISO 9001 or ISO 14001. This makes it easier for organisations to integrate energy management into their overall efforts to improve quality and environmental management. ISO 50001:2011 provides a framework of requirements for organisations to:
Effective energy management isn’t just good for business, it’s also becoming a requirement and the best way to achieve this is with ISO 50001. The international standard outlines energy management practices considered to be the best, globally. Energy management specialists from over 60 countries developed the standard and now we can help you tap into that expertise, every day to help you save energy, cut costs and meet environmental requirements.
At PSW, we believe that by both adopting and then implementing the principles outlined by the international ISO 50001 standards for energy, it will enable a detailed understanding of your energy consumption; identify underlying factors which impact on consumption; and set appropriate targets that allow you to review performance. This will subsequently allow you to identify avoidable waste or other opportunities to reduce consumption.
New UK regulations came into force in December 2014 that effect landlords and property owners. It is part of a wider European Energy Directive enabling end tenants to reduce their heating costs and there are three issues to be addressed:
Each heat supplier must register with the National Measurement Office (NMO) before the end of 2015 (this is an amended date from the original 15th April 2015) of the location, size and supply details of existing buildings. Each building needs to be identified, along with the number of end users and how these tenants receive information or are billed.
Schemes with multiple buildings are required to have a heat meter to be installed at the incoming heat entry to each building. These ‘bulk meters’ must be in place by the 30th April 2015.
For each tenant or customers within the building the landlord must evaluate the feasibility of installing end tenant meters or heat cost allocators (radiator meters). As the heat supplier you need to complete a building survey and if it is found feasible then the meters must be installed by December 2016.
The benefits that heat meters provide are:
End customers must be billed using actual meter readings. This provides customers with transparency in consumption to reduce energy, whilst paying for only what they are using.
