Renewables qualifications explained
MCS certification is the primary quality standard for renewable energy installers in the UK. Here is what the key schemes mean and which type of installer they apply to.
The government-backed quality standard for small-scale renewable energy installations. MCS certification is mandatory for heat pump, solar PV, solar thermal, battery storage and biomass boiler installers if the homeowner wants to claim the Boiler Upgrade Scheme grant or Smart Export Guarantee tariff.
TrustMark is the government-endorsed quality scheme for tradespeople working in and around the home. Required for installers carrying out work funded through ECO4 and other government energy efficiency schemes. Acts as an additional quality layer alongside MCS.
PAS 2035 is the publicly available specification for retrofit of domestic buildings. A PAS 2035 Retrofit Coordinator must oversee all government-funded retrofit work including ECO4 and GBIS. Required when multiple measures are installed or when a whole-house retrofit approach is taken.
OZEV approved installer status is required for EV chargepoint installers whose customers want to claim the Electric Vehicle Chargepoint Grant for residential or workplace installations. Installers must also be registered with NICEIC, NAPIT or another competent person scheme as a Part P electrician.
Passivhaus Designer or Certifier qualification from the Passivhaus Institut (Germany) or the Association of Passive House Practitioners (APHA) in the UK. Required for buildings seeking formal Passivhaus certification. Demonstrates expertise in ultra-low energy design and PHPP modelling software.
Always ask any renewable energy installer for a current Public Liability Insurance certificate before work begins. A minimum of £2 million cover is standard for domestic installations. MCS certification requires installers to hold adequate PLI as a condition of registration.
