MCS-certified Solar PV Installers in Cardiff

Grants in the United Kingdom for solar PV work in Cardiff

The Boiler Upgrade Scheme pays a fixed grant toward a certified heat pump in England and Wales. ECO4 funds insulation and heating upgrades for eligible low-income households through the energy suppliers.

Boiler Upgrade Scheme (BUS)

BUS is a flat grant, claimed by an MCS-certified installer at the point of install. It covers air-source and ground-source heat pumps in England and Wales; Scotland and Northern Ireland run separate schemes.

What BUS needs

The property needs a valid Energy Performance Certificate and an installer on the MCS register for that technology. The grant is deducted from the quote, not paid to you later.

ECO4

ECO4 is an obligation on large energy suppliers, not a form you send to government. It typically funds loft, cavity, or solid-wall insulation plus heating upgrades for households that meet the income or vulnerability rules.

For this trade

Neither BUS nor ECO4 is a general solar-PV grant. Some ECO4 jobs add generation kit; most rooftop PV is privately funded.

The MCS number on the listing should match the certificate the installer uses on the BUS or ECO4 paperwork.

Figures and income bands change. Check the official programme page before you budget, and ask the installer which rate they can actually claim.
