opened the Renewable Heat Incentive (RHI) on 25th November 2011,
for industrial, commercial, public sector and not-for-profit and
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.
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. 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 case,

RHI non domestic tariffs are published here
For the domestic RHI the tariff level is set at 12.2pkWh
for Biomass-only boilers and biomass pellet stoves with
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.

In order to ensure the sustainability of biomass fuel,
sustainability criteria for the Governments Renewable Heat
Incentive scheme, will dictate that, from Spring
2015, 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.

requirements for the Renewable Heat Incentive,

sustainability requirements for the domestic RHI,
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 RHI accreditation of any new biomass installations from the
24th of September 2013, Ofgem will require proof that the boiler
complies with flue emissions limits of 150g/GJ of nitrogen oxides
and 30g/GJ of particulates. Ofgem have not yet confirmed exactly
how they intend to police this.
From September 2013, all applicants with biomass boilers will
need to submit an RHI emission certificate or a valid environmental
permit with their application. For further information, see the
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 RHI:
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
