What is MCS? – Your Complete Guide to MCS Certification
Published · 4 min read

If you work with renewable energy technology as an installer or you make products, knowing about the Microgeneration Certification Scheme (MCS) is very important. This certification shows that your work or your product meets high standards. It tells your customers that they can trust what you sell or install.
Overview of MCS
MCS stands for the Microgeneration Certification Scheme. It is a big deal in the UK and helps promote the use of small-scale renewable energy like solar panels and wind turbines. MCS doesn’t just check products; it also checks the companies that install them, to make sure everything is top-notch.
This scheme does not directly certify companies itself. Instead, it allows specific certification bodies to do that job. This ensures that everyone is evaluated fairly and meets high standards.
Why MCS Certification Matters
Getting MCS certification is not just about making your business look good. It has real benefits, like helping you get government money for using renewable energy. Here’s why it’s super useful:
- Quality Assurance: If your products and services are MCS-certified, it means they are reliable and of good quality.
- Consumer Confidence: Customers are more likely to trust and buy your products if they are certified.
- Environmental Impact: Using MCS-certified products helps the environment by reducing harmful emissions and promoting sustainability.
Who Should Seek MCS Certification?
This certification is mainly for businesses that install or produce small-scale renewable energy solutions. If you work with technologies like solar panels or wind turbines, this certification tells your customers that you are doing things the right way.
Key Benefits of Being MCS Certified
Having MCS certification can really help your business. Here are some of the best reasons to get certified:
- Government Incentives: You often need this certification to qualify for government programs that support renewable energy.
- Better Business Prospects: It can help you stand out in the market and attract more customers.
- Meeting Standards: It shows you meet specific high standards in quality and service.
How to Become MCS Certified
Becoming an MCS-certified installer involves several steps. Here is what you need to do:
- Learn what MCS expects from you. This includes how you handle customers and the quality of your technical work.
- Set up a good management system in your company that covers everything from your first customer contact to the finished installation.
- Pick an MCS-certified body to check your business. This body should be approved by the UK Accreditation Service (UKAS).
- Go through an assessment where your business practices and installations are checked.
- Fix any issues found during the assessment to make sure you meet all the MCS standards.
- Once you pass everything, you are MCS-certified. To keep your certification, you need to show you still meet the standards every year.

Is MCS Certification Legally Required?
It’s not a legal requirement to be MCS certified, but it is often needed if you want to benefit from some government energy schemes. More than that, having MCS certification is a good way to show that you’re serious about quality and efficiency in your work.
Cost of MCS Certification
The cost to get MCS-certified can vary depending on many things, like the size of your business or the type of technologies you install. Generally, you might pay between £1,000 and £5,000 each year, which covers training, application fees, and audits.
Differences Between Product and Installer Certification
MCS offers two main types of certification:
| Type of Certification | Focus |
| Product Certification | Checks that products meet specific safety and performance standards. |
| Installer Certification | Verifies that installers are skilled and perform work to high standards. |
Technologies Covered by MCS Certification
MCS covers a wide range of technologies. Here are some of the main ones:
- Solar Photovoltaic (PV) systems – These turn sunlight into electricity.
- Heat pumps (air and ground source) – These use heat from the air or ground to warm buildings and water.
- Wind turbines – These generate electricity from wind.
- Battery storage systems – These store electricity for later use.
MCS certification helps ensure that all these technologies work well and safely. This helps customers trust in renewable energy solutions more. Plus, it makes your business part of a cleaner, greener future.
