What is an EPC?

Energy Performance Certificates (EPCs) are needed whenever a property is built, sold or rented.

An EPC contains:

• Information about a property’s energy.
• Recommendations about how to reduce energy use.

An EPC gives a property an energy efficiency rating from A (most efficient) to G (least efficient) and is valid for 10 years.

To produce an EPC, an accredited assessor inspects the property, divides it into zones depending on the purpose (eg: toilet, corridors) puts the data into the modelling program and produce the certificate with the rating.

The procedure compares the candidate building with a notional building generated by the software.


With the increasing sophistication of modern heating systems, there has been steady development over the last 30 years of control systems which manage energy use in the whole building rather than just the boiler.

Known as a building energy management system (BEMS), it will use input parameters from outstations around the building measuring temperatures, flows, valve positions and in some cases humidity.

The use of BEMS can save at least 15% of the total energy consumption in a building. To gain the maximum benefit from the system, it is essential that site based staff are proactive in using it.

Scottish waste regulations

In Scotland, zero waste regulations came into force on the 1 January 2012.
The regulations require all businesses and organisations to separate key materials – plastic, glass, metals, paper and card – for recycling, while most food businesses are also required to separate food waste for collection.  

The regulations intend to:

• Maximise the quantity and quality of materials available for recycling and minimise the need for residual waste treatment capacity;
• Move residual waste away from landfill so as to generate energy from those materials we can’t recycle;
• Drive cultural shifts in how waste is managed;
• Create the market certainty needed for investment in the sector.
