Accreditations

Trusted, Certified & Compliant Renewable Energy Experts

At Silverstone Green Energy, we believe that quality, safety, and transparency are the foundations of every installation we deliver.

Each project is completed with care, precision, and full compliance — ensuring our systems perform efficiently and stand the test of time.

Our accreditations reflect this ongoing commitment to the highest industry standards, giving our customers complete confidence that every solution we design and install meets strict technical, environmental, and regulatory requirements while delivering long-term reliability and value.

NAPIT stands for the National Association of Professional Inspectors and Testers — one of the UK’s leading Government-approved accreditation bodies for electrical work.

Being NAPIT-certified means Silverstone Green Energy has been independently assessed to ensure all our electrification installations — including solar PV, battery storage, EV charging, and associated wiring — are designed, installed, and tested to meet the latest safety regulations and industry standards in both homes and businesses.

Over the years, we’ve continued to stay at the cutting edge of renewable technology, constantly developing our skills, knowledge, and technical capability.

In 2016, Silverstone Green Energy became one of Wales’s first certified Tesla Powerwall installers, allowing us to supply and fit both Tesla Powerwall batteries and Tesla electric vehicle charge points.

Since then, we’ve successfully installed hundreds of Powerwall systems across homes and businesses throughout Wales, helping customers achieve greater energy independence and efficiency.

We are proud members of the Renewable Energy Consumer Code (RECC), demonstrating our commitment to fairness, transparency, and customer care.

As a RECC-accredited installer, we adhere to the high standards of consumer protection set out by the code, ensuring every customer receives honest advice, clear documentation, and professional service from start to finish.

By choosing a RECC member, homeowners can have complete confidence that their small-scale renewable energy system will be installed safely, effectively, and in full accordance with industry best practices — delivering reliable performance and lasting value.

As part of our commitment to high standards and exceptional quality, Silverstone Green Energy is accredited by TrustMark — the only Government-endorsed quality scheme for tradespeople in the UK.

This accreditation recognises our dedication to delivering work that meets rigorous standards of technical competence, customer service, and consumer protection.

It gives our clients the assurance that every project we undertake is carried out responsibly, safely, and in line with the Government’s recognised best practices for the renewable energy industry.

We’re committed to giving every customer long-term confidence in their installation, which is why we provide QANW Insurance Backed Guarantees (IBGs). An IBG protects you if a contractor ever stops trading, ensuring the terms of their written workmanship guarantee are still honoured.

If a fault arises within the guarantee period and the original contractor is no longer in business, QANW can cover the reasonable cost of putting things right—up to the value of the original contract. QANW works alongside recognised industry and government-endorsed schemes, offering trustworthy protection for homeowners. You can view the full QANW Homeowner Guide here:
