community installations. The domestic RHI was launched on the 9th

All wood fuel consumers who install (or who have recently
installed) a wood fuel system and use it to generate heat will be
eligible for the scheme.
Note: if the system is owned by an energy services company
(ESCo) they will be eligible for RHI, not the consumer.
Key features of the scheme:
- System of tariffs based on amount of heat generated
- Quarterly payments for 20 years for the
non-domestic RHI, from the date consumers enter
the scheme, quaterly payments for 7 years for the domestic
RHI from date of entry.
- All eligible installations since 15 July 2009 will qualify
- The scheme does not cover biomass direct air heating, only heat
produced via the medium of hot water.
- From October 2015 end users must comply with sustainability
crtieria to be eligible for RHI payments.
RHI regulations are
For the Domestic RHI:
Applicants for the domestic RHI will need to complete a Green
Deal Assessment before submitting their application and must ensure
they have met minimum loft (250mm) and cavity wall insulation
requirements, where appropriate. Ofgem intend to allow
Registered Social Landlords to apply for the domestic RHI without a
Green Deal Assessment but they will still need to have an Energy
Performance Certificate that is less than two years old so that RHI
payments can be calculated.
All installations and installers must be Microgeneration
Certified Scheme (MCS) certified (or certified by an
equivalent scheme). Please note that the current upper limit for
the MCS scheme is 45kW, if your requirement is for a boiler
over 45kW please contact Ofgem to discuss your individual

RHI & Combined Heat and Power (CHP):
A new renewable CHP installation currently has two options
through which to receive support:
New CHP stations accredited on or after 1st April 2015 will
receive support from a combination of the RO and RHI.
Ofgem have published guidance
for anyone involved with the RHI and sets out how Ofgem
will administer the scheme.

· sight of all the questions in the
application form so you can prepare in advance.
· a checklist and help with
answering some of the key questions
· screenshots and step-by-step
instructions on how to use the RHI Register.

In order to ensure the sustainability of biomass fuel and
subject to Parliamentary Approval, the Department of Energy
and Climate Change plan to introduce biomass sustainability RHI
regulations in Spring 2015, with the obligation on RHI
participants to meet the sustainability requirements from October
2015 (currently taken to be Monday 5th
October). In order to be eligible for the
RHI, biomass installations will be required to demonstrate, either
through reporting or sourcing from an approved supplier, that their
biomass fuel meets a minimum 60% GHG emission saving relative to EU
fossil fuel heat average and land criteria which correspond to
meeting the UK Timber Procurement Policy.
Biomass installations of 1 MWth capacity and above will be
required to report quarterly on the sustainability of their biomass
feedstock for combustion and where they are used to produce biogas.
This information will include the amount of biomass used, its type
and form, country of origin and whether an environmental
accreditation has been met. DECC intends to implement
land-use sustainability criteria by 1 April 2015, from this
date RO/CfD generators and RHI participants with a total
installed capacity greater than (or equal to) 1MW, will be expected
to prepare an annual sustainability report which is compiled by a
third party auditor/verifier in accordance with ISAE 3000 or

Metering requirements were simplified in September 2013 -only
the minimum number of meters necessary to calculate the RHI payment
are now required. They also allow heat loss from external pipework
to be disregarded (in certain circumstances) where can be
considered it properly insulated. In addition, applicants who can
prove that it is either physically or financially overly burdensome
to install a heat meter, will instead be allowed to submit a heat
loss calculation in place of installing additional meters.
For biomass boilers installed after the 24th of September 2013,
in order to be eligible for the RHI Ofgem will require proof that
the boiler complies with flue emissions limits of 150g/GJ of
nitrogen oxides and 30g/GJ of particulates. In order to
comply with emissions limits RHI claimants can only burn
fuel that is listed on their emissions certificate. They
must also use fuel that meets the maximum moisture content
threshold shown in their emissions certificate, fuel
receipts confirming the moisture content of the fuel must be kept.
RHI claimants who supply their own fuel must test the
moisture content of their own fuel, guidance on testing moisture
content can be accessed
As of September 2013, all applicants with biomass boilers must
submit an RHI emission certificate or a valid environmental permit
with their application. For further information, see the Ofgem
click here to access.
Accredited installations can be relocated, providing the
installation meets the necessary requirements at its new
Enhanced Capital Allowances (ECA's) and the
ECAs are not available in respect of
expenditure on plant or machinery when it generates electricity or
heat that attracts tariff payments under either of the FiTs or RHI
schemes. ECAs may still be claimed (subject the other conditions of
the ECA schemes) in respect of expenditure on such equipment as
long as no tariffs are paid. Any ECAs given, in respect of
expenditure incurred from April 2012 (or April 2014 for CHP
installations), will be withdrawn if FITs or RHI tariffs are paid
