Feed-in Tariffs (FITs) • New Government financial incentive for all renewable electricity up to 5MW
• Based on very successful schemes elsewhere such as in Germany • Started 1 April 2010
• Designed to provide 5-8% return on investment • Different tariffs depending on type and scale of technology • Paid for all electricity generated and not just that exported to the grid • 3p/kWh extra if you export to the grid • Various eligibility criteria

In almost all cases, you will still need to buy electricity from the grid
Renewable Heat Incentive (RHI) • Out for consultation under the previous Government
• New Government financial incentive for renewable heat • First country in the world to introduce • Proposed to start 1 April 2011
• Designed to generate 12% return on investment, apart from solar thermal (6%) • Different tariffs depending on type and scale of technology
• Various eligibility criteria • New Government “committed to increasing the amount of renewable heat in the UK” & is currently looking at the RHI & will make an announcement “as soon as possible”

!! Important !! • To be eligible for the Feed-in Tariff (FITs) or the Renewable Heat Incentive (RHI) your installation must be installed by a Microgeneration Certification Scheme (MCS) approved installer using a MCS approved product • List of SW based MCS installers, which is updated weekly, available from www.regensw.co.uk/projects/microgeneration

“Expensive and unnecessary” ref. suspension of CSH rating for new homes „I endorsed the concept of building all new homes to a zero carbon standard, and that remains my position‟
Grant Shapps Minister for housing and local government
„I will be publishing a final zero carbon definition in a matter of weeks‟
„The renewables industry will come of age under this Government...our coalition agreement is explicit in its support for the sector‟ „I want to see more homes, communities and businesses generating their own energy‟ & „work with industry to overcome the challenges it is facing. „ „We are committed to an ambitious renewable heat agenda‟. „renewable heat will be a key part of‟ our strategy‟
