A guide to grants and incentives for Installers

MCS is an eligibility requirement for the various incentive programmes available, but we do not administer any of these schemes.


The Smart Export Guarantee (SEG) will ensure that households and businesses with small-scale renewable technologies, are paid for exporting their excess electricity to the grid.

MCS certification (or equivalent) will be a requirement to qualify for the SEG, helping to safeguard high standards in the industry.

SEG builds on the government’s previous subsidy scheme, the Feed-in Tariff (FiT), which supported the installation of 850,000 renewable projects. The FiT closed to new entrants in April 2019.

Under SEG, energy suppliers will be required to offer a payment for the electricity households with solar PV panels, and other small-scale renewable electricity generators, export to the grid.

The legislation puts a legal obligation on energy suppliers with over 150,000 customers to introduce export tariffs by 1st January 2020.

All customers will be able to sign up for new export tariffs once they go live on the 1st January 2020 (or from now with Octopus).

If they are already in receipt of FiT, they will have to decide which to keep, either the FiT payment or the export tariff. However, new installations between the 1st April 2019 and 31st December 2019 must be MCS certified to qualify for SEG. This is because MCS certification cannot be applied retrospectively to an installation.

Export tariffs are not like government incentives. The terms for an export tariff are set by the energy supplier, who will only pay for the electricity they receive from the date on which the tariff is applied to a consumer’s energy supply/account.

To be eligible for RHPP and non-domestic RHI incentives, the product and the installation company must be MCS certified at the time of commissioning.

Please note that heating technology products eligible for the domestic RHI must also be listed in our Product Directory.


Low Carbon Workspaces offers small and medium-sized businesses in Buckinghamshire, Berkshire and Hertfordshire grants of between £1,000 and £5,000 to cover up to a third of the cost of making energy improvements in their commercial premises.

The scheme supports upgrades such as LED lighting and energy-efficient heating systems, as well as renewable energies such as solar PV and biomass boilers – applicants will still qualify for SEG.

Installations must replace existing inefficient equipment and an energy saving must be seen – the grant team will be able to identify this.

To apply, all that’s needed is 12 months energy bills, a quote for the new equipment and a completed application form, downloadable here.

Applications go to a Grant Panel who provide a decision within 5 working days after which the upgrades can be installed and paid for in full. The grant amount will be reimbursed within 30 days of submitting a claim.

There are limited grants available so contact a member of the team today to discuss an energy upgrade project on 01494 927131.

The programme is funded by the European Regional Development Fund (ERDF) and managed by Ngage Solutions, a not-for-profit company that specialises in the design and delivery of grant schemes and business support programmes.

If your customer lives in Scotland, they could benefit from an interest free loan for investing in a range of low carbon technologies.

The amount of funding depends on what improvements they want to make.

The loan is only available for properties in Scotland.

The FiT was introduced on 1st April 2010 and closed on 31st March 2019.

The scheme requires participating licensed electricity suppliers (FiT Licensees) to make payments on both generation and export from eligible installations. Both the product and installers must be MCS certified.
