Why is certification so important?
Having the right certification in place isn’t just about ticking boxes. If you don’t have the right certification, you can face penalties, fines, and even prison time. That’s why it’s so important to understand your responsibilities.
Electrical safety and compliance
BS 7671 is the British Standard for "Requirements for Electrical Installations.” You may also hear these referred to as IET Wiring Regulations.
You don’t need to understand all the regulations – that’s the job of your electrical contractor. However, there are some terms you should be familiar with.
Electrical Installation Certificate (EIC)
An Electrical Installation Certificate (EIC) is required for new installations, when there is a change of distribution board, or when a new circuit is added. They are usually issued when a property undergoes a full rewire or when it is a new build.
The certificate declares that the installation is safe to use in line with the BS 7671 regulations. You may also hear it called a BS 7671 electrical safety certificate. An EIC typically lasts for five years.
Electrical Installation Condition Report (EICR)
EICR stands for Electrical Installation Condition Report. You might also hear it referred to as periodic inspection or fixed wire testing.
It involves an in-depth inspection of your internal wiring to check the condition and identify any issues, such as damage or deterioration. The EICR also includes fixed wire testing to ensure that wiring is not degrading over time.
Commercial properties should get an EICR every five years or whenever there is a change of occupancy. Industrial facilities – manufacturers, warehouses, and workshops, for example – should get an EICR every three years.
Failing to obtain a valid EICR certificate or neglecting to address any identified defects can have severe consequences. These include legal sanctions such as fines and imprisonment, insurance implications, and reputational damage.
Portable Appliance Testing (PAT)
An EICR covers your fixed wiring and electrical installations. PAT, on the other hand, covers your portable appliances. These include:
• Portable, handheld, or moveable appliances and equipment
• Stationary or fixed appliances and equipment
• IT equipment
• Extension leads and RCD extension leads
• Multi-way adaptors and RCD adaptors
There is no specific law around PAT testing, but employers do have a legal requirement to ensure the safety of any electrical equipment, so it is recommended that equipment is inspected and tested every 3-12 months, depending on:
• Equipment type
• Equipment class
• Frequency of use
• Age of equipment
• If equipment is moveable or static
• Competence of personnel using the equipment
• Where equipment is used (e.g. ATEX areas)
• Previous test results
• Manufacturer's guidelines and recommendations
• Equipment modifications or repairs
PAT testing doesn’t have to be carried out by a qualified electrician, but it should be carried out by a competent person using suitable equipment.

Energy and consumption
Now we’ve covered your responsibilities for electrical safety, let’s look at energy performance, more specifically EPCs.
What is an EPC?
An Energy Performance Certificate (EPC) tells you how energy efficient a building is, giving a rating from A (very efficient) to G (inefficient).
An EPC is required when:
• You rent out or sell your premises
• Construction of a building is completed
• There are changes to the number of parts used for separate occupations and these changes involve providing or extending fixed heating, air conditioning or mechanical ventilation systems
Do you need an EPC by law?
In England and Wales, the penalty for failing to provide an EPC when required is between £500 and £5000 depending on the rateable value of the building. A penalty can be issued for each building or unit that is found to be in breach of the requirement.
In addition, it is an offence to give false or misleading information on an EPC, and penalties can be imposed for this offence as well.

Benefits of an EPC
While an EPC is only required in certain circumstances, there are benefits to obtaining one even if it isn’t compulsory. An EPC will help you understand where the inefficiencies are within your building so they can be addressed.
This can help you reduce your carbon footprint and meet your sustainability goals as a business.
Staying compliant and energy efficient with AES
At AES, we specialise in electrical contracting services for manufacturers. We can install, test, inspect, service and maintain your lighting and emergency lighting and any electrical installations, including plant equipment and machinery. AES personnel are also CompEx accredited to work in ATEX areas.
Not only do we offer proactive and reactive maintenance and emergency callouts, but we also offer a range of specialist services for manufacturers to improve efficiency.
These include energy storage, voltage optimisation, variable speed drives, and control and automation systems.
To get you started, we offer a free energy reduction audit to help you understand where you can make the most significant impact and which energy-saving solutions are right for you.
After completing our assessment, we’ll provide you with a full report detailing energy consumption savings and the real cost savings to your business.
Our goal is to help you reduce energy consumption in the most effective way so you can generate a return on investment as quickly as possible.
Contact us to find out more, book your EICR inspection, or request a free energy reduction audit.
You Cannot Secure What You Cannot See: Building an OT Asset Inventory
A production line rarely arrives as one neat, self-contained system and stays that way. It acquires a replacement drive here, a new HMI there, a remote support connection added during an urgent breakdown, and perhaps a reporting link into the wider business network. Each change may be sensible on its own, yet over several years […]

BS 7671 Amendment 4: What Industrial Sites Need to Review Before October 2026
A change to the Wiring Regulations will not stop a production line on the day it is published. Its effects are usually felt more quietly: in a design decision, a procurement specification, a shutdown plan or a certificate that has to stand up to scrutiny months later. For industrial businesses, that makes the transition to […]

Power and Distribution: Ensuring Load Capacity Matches Modern Demands
Manufacturing sites have changed significantly over the last decade. Many factories are running more automated equipment, more digital systems, more efficient lighting, more sophisticated control panels and, in some cases, new electrical demands such as EV charging, battery storage or additional production lines. The issue is that not every site’s electrical infrastructure has changed at […]

Variable Speed Drives: Boosting Efficiency Without Sacrificing Performance
Energy reduction remains a major priority for UK manufacturers. Rising operating costs, pressure to reduce carbon emissions and the need to maintain competitiveness have all pushed factories to look more closely at how energy is being used across their sites. In many manufacturing environments, one of the best places to start is with motors. Motors […]

Electrical Documentation and Labelling for Safety and Traceability
In a busy manufacturing environment, electrical systems are often changed, extended and adapted over many years. New machines get installed, control panels get modified, production lines are relocated, additional lighting is added and distribution boards get upgraded. Over time, what began as a well-documented installation can become difficult to follow if records are not updated […]

What a Factory Acceptance Test (FAT) Should Include and Why It Matters
Installing new machinery, production equipment or automated systems into a factory is rarely a small decision. For most manufacturers, it involves significant capital investment, careful planning, disruption to normal operations and a clear expectation that the new equipment will improve output, efficiency, quality or safety. That is why a Factory Acceptance Test, often shortened to […]
