The standards we are independently assessed against, what each one covers, and what it actually means for you as a customer. Now MCS certified for solar PV and battery storage, and Gas Safe registered for gas work.
Independently certified
MCS certified for solar PV and battery storage
MCS is the UK’s quality mark for small scale renewable and low carbon technologies, such as solar panels and home batteries. Installers only get it after an independent, UKAS accredited certification body has assessed how they design, install and hand over their systems.
Energy Giants is MCS certified for solar PV and battery storage. The certificate is below. Open it, download it, or check the number with MCS yourself.

What it means for you
Checked by someone other than us
An independent certification body, Simply Certification, assessed how we design, install and hand over solar PV and battery systems before certifying us, and audits us to keep it. Simply Certification is itself accredited by UKAS.
Installed to the MCS standards
Solar PV is installed to MIS 3002 and battery storage to MIS 3012. They cover how the system is designed and sized, the performance estimate you get before you commit, and how it is installed, commissioned and handed over.
An MCS certificate for your installation
When your solar or battery system is finished we register it on the MCS Installation Database and you get an MCS certificate for it. Keep it with your house paperwork. It is useful if you sell.
Paid for what you export
For solar PV, energy suppliers usually ask for the MCS certificate before they pay you for the electricity you send back to the grid under the Smart Export Guarantee.
A consumer code behind the work
We are committed to the Renewable Energy Consumer Code, which sets out how we quote, install and handle complaints, and what happens if something goes wrong.
Clear about what it covers
Our MCS certificate covers solar PV and battery storage. It does not cover heat pumps or other renewable technologies. If a quote from any installer includes something the certificate does not name, it is not covered.

Our accreditations
Accreditation is not a badge we award ourselves. Each one below is issued by an independent body, has a scope that defines exactly what it covers, and has to be renewed.
PAS 2030:2023
Certified
PAS 2030 is the British Standard that governs how energy efficiency measures are installed in existing buildings. Certification is assessed by an independent certification body and is a requirement for installers delivering measures under government-backed retrofit schemes.
What this means for you
Your installation is carried out to a published national standard rather than to whatever the installer considers good enough. The work is auditable, the certification body can be asked to verify it, and if a measure is delivered under a government scheme the certification is what makes that funding possible.
TrustMark is the government-endorsed quality scheme for work carried out in and around the home. Registered businesses are vetted against standards covering technical competence, customer service and trading practices, and are subject to ongoing monitoring.
What this means for you
You get a route to independent recourse that does not depend on the goodwill of your installer. Registered work is recorded on the TrustMark Data Warehouse, and TrustMark can step in if something goes wrong — which matters most on exactly the kind of work you cannot inspect once it is finished.
Gas Safe Register is the official list of businesses and engineers allowed to work on gas, appointed by the Health and Safety Executive. By law, anyone who installs, services or repairs a gas boiler, cooker or fire in your home must be on it. Energy Giants is a Gas Safe registered business.
What this means for you
Any gas work in your home, such as fitting a gas boiler as part of first time central heating, is carried out by a Gas Safe registered engineer. Every registered engineer carries a Gas Safe ID card with their photo and licence number, and the back of the card lists the types of gas work they are qualified to do. Ask to see it and check it covers your job.
A new gas boiler is notified through Gas Safe Register, which sends you a Building Regulations Compliance Certificate. You can check our registration yourself on the Gas Safe Register using our number, 986000.

An insurance backed guarantee (IBG) is a policy that stands behind an installer’s written workmanship guarantee. Energy Giants is accredited under the Bluedrop Insurance Backed Guarantee Facility as an Accredited Installation Management Company, which means we can issue IBG policies on our installations through the Bluedrop scheme. Bluedrop Services (NW) Limited is an insurance broker authorised and regulated by the Financial Conduct Authority, and is authorised by TrustMark to issue IBGs for measures delivered under the government ECO4 scheme.
What this means for you
A written guarantee is only as good as the company behind it. If an installer ceased trading during the guarantee period, an ordinary guarantee would go with it. With an IBG, an insurer takes on the obligations of that written guarantee for its remaining term, so the protection does not depend on the installer still existing. Ask for the policy document with your handover pack and keep it with your other paperwork.
Every accreditation has a scope — the specific measures it covers — and an expiry date. A certificate that does not name the measure being installed on your home does not cover that work, however impressive the logo looks. We publish our certificate numbers and scopes above so you can check them directly with the issuing body rather than taking our word for it.
If you are getting quotes from more than one installer, asking each for their certificate number and the measures it covers is the single most useful question you can put to them.
Want to check a certificate?
Ask us for the certificate number covering the measure you are considering, and check it with the issuing body. We would rather you verified it than took our word for it.
