Understanding the terminology used in renewable energy installations, accreditation, and compliance. From SIP to RGMA, we explain it all.
Consolidated Metering Code of Practice - the industry code that sets competency standards for personnel installing, maintaining, and removing gas and electricity meters.
Commissioning is the final stage of installation where systems are tested, configured, and verified to work correctly before handover to the customer.
The cut-out or service head is the point where the DNO's electricity supply terminates and the customer's installation begins, containing the main service fuse.
Electralink operates the Data Transfer Service (DTS) for the UK electricity industry, enabling secure data exchange between suppliers, distributors, and other market participants.
Electricity Metering Operative accreditation allows organisations to install, replace, repair, and maintain electricity metering equipment under the REC.
An Energy Performance Certificate rates a property's energy efficiency from A to G, required when selling or renting and for accessing certain renewable energy incentives.
Export limitation restricts how much electricity a solar or battery system can send to the grid, required when local network capacity is constrained.
G98 is the DNO notification process for small-scale generation systems up to 16A per phase (3.68kW single-phase), allowing 'fit and inform' installation without pre-approval.
G99 is the engineering recommendation governing the connection of generation equipment to distribution networks, requiring DNO approval for systems over 16A per phase.
A handover pack is the complete documentation package provided to customers upon installation completion, including certificates, warranties, and operating instructions.
Heat pumps extract warmth from air, ground, or water to heat buildings efficiently, eligible for government incentives when installed by MCS-certified installers.
Meter Asset Managers are responsible for the ownership, installation, maintenance, and data management of gas meters throughout their lifecycle.
Microgeneration Certification Scheme certification is required for installers to provide renewable energy systems that qualify for government incentives and feed-in tariffs.
Meter Operators are appointed by electricity suppliers to manage metering equipment including installation, maintenance, and data collection.
The MPAN is a 21-digit reference identifying electricity supply points in Great Britain, with a 13-digit core used for billing, switching, and industry communications.
The MPRN is a unique 6-10 digit number identifying every gas supply point in Great Britain, used for billing, switching suppliers, and industry data flows.
RAMS documents outline the hazards, risks, and safe working procedures for specific tasks, required for health and safety compliance on energy installation projects.
The Retail Energy Code governs retail energy market operations in Great Britain, setting rules for suppliers, meter operators, and data exchange.
RGMA is the industry framework and data exchange system for gas meter asset management, enabling automated flows between suppliers, shippers, MAMs, and transporters.
The Smart Export Guarantee requires licensed electricity suppliers to offer payment for exported renewable electricity from small-scale generators like solar PV.
Safe Isolation Provider accreditation enables Metering Equipment Managers to legally de-energise and re-energise electricity supplies without DNO appointments.
Smart meters are digital gas and electricity meters that automatically send readings to suppliers, enabling accurate billing and real-time energy monitoring.
Second-generation smart meters that communicate via the national Data Communications Company (DCC) infrastructure, enabling supplier switching without losing smart functionality.
Solar photovoltaic systems convert sunlight directly into electricity using semiconductor cells, enabling homes and businesses to generate their own renewable power.
