MCS
Microgeneration Certification Scheme
The standard that protects grants, SEG eligibility and consumer rights.
MCS certification is a hard requirement for every installer on our panel. Without it you lose access to the Smart Export Guarantee and most grant routes, so it is the first thing we check and the one criterion we never waive.
EPVS
Energy Performance Validation Scheme
Independent validation of the performance figures on your quote.
All of the installers we work with are registered with EPVS. It means the generation and savings figures printed on your quote have been produced to an independently validated standard rather than an optimistic sales estimate.
NAPIT
National Association of Professional Inspectors and Testers
Competent-person registration for the electrical work on your install.
Solar, battery and EV charger installations are notifiable electrical work. Competent-person registration means the electrical side is self-certified to the required standard and properly notified.
TrustMark
Government-endorsed quality scheme
Covers workmanship, trading standards and customer protection.
TrustMark registration brings technical competence, trading standards and customer-service requirements under one government-endorsed framework, with a route to raise a complaint if something goes wrong.
HIES
Home Insulation and Energy Systems consumer code
Deposit protection and independent dispute resolution.
A consumer code adds deposit protection and access to independent dispute resolution on top of the installer's own guarantees, which matters most on the rare job that does not go to plan.
IWA
Insurance-backed workmanship guarantees
Cover that holds even if the installer ceases trading.
Every installer we recommend carries workmanship guarantees underwritten by an independent insurer. If the company were to stop trading, the cover still stands, which is the single biggest protection gap in this industry.
FCA-approved finance
Financial Conduct Authority authorisation
Regulated finance, not the cheapest headline rate.
Any installer on our panel offering finance is FCA-authorised. That means they have passed regulatory checks on how credit is sold, even where their rate is not the lowest available.
Being straight about what we hold ourselves
The Solar Broker is not currently a member of RECC, TrustMark or HIES in its own right, and we would rather say so than imply otherwise. We are a broker and advisor. All of the installers we work with are registered with the Energy Performance Validation Scheme, and we carry £1 million Public Liability insurance and are dbs certified.
