London boiler scrappage scheme 

As part of The Mayor’s strategy to reduce Londons emissions 60% by 2025, the London Boiler Cashback Scheme will provide 6,500 homeowners and private landlords each with £400 cashback on replacing 70% efficient or less boilers.

To qualify for the £400 cashback boiler replacement scheme, you must meet the following requirements:

  • The property must be a home located in the Greater London area
  • Applicants must be homeowners or private landlords
  • The boilers being replaced must have an efficiency rating of 70% or lower and be
    gas, oil, LPG or solid fuel
  • The boilers being replaced must be in working order and used to heat the home
  • Replacement boilers must be at least 90% efficient

Domestic Renewable Heat Incentive (RHI)

What is Domestic RHI?

The Domestic Renewable Heat Incentive, otherwise known as the Domestic RHI scheme, is a government financial incentive scheme set up to encourage the installation and usage of renewable heating technologies in existing homes.

Launched in Spring 2014, the scheme enables those using renewable heating systems to receive quarterly payments at a set rate (kilowatt hour, kWh) per unit of clean, green renewable heat their system produces.

Who is the Domestic RHI scheme for?

The Domestic RHI scheme covers single domestic properties and is open to home owners, private landlords, registered providers of social housing, third party owners of heating systems and self-builders. It is available to households both off and off of the gas grid.

For non-domestic properties such as those that are the premises for businesses, schools and hospitals etc. there is a separate scheme called the Non-Domestic RHI.

At Viessmann, we offer a comprehensive range of heating systems that are eligible for the Domestic RHI scheme. These include air source heat pumps, ground source heat pumps, biomass boilers and solar thermal technology.

Domestic RHI payment tariffs

Once you have joined the domestic RHI, you'll remain on the same tariff rate.
 

Why take part in the scheme?

Taking part in the Domestic RHI scheme will enable you to help the environment and save yourself money at the same time.

The scheme is a government financial incentive to promote the use of renewable heat. Switching to heating systems which use renewable energies in place of fossil fuels will help the UK reduce its carbon emissions. As fossil fuels are finite resources that are steadily increasing in price year on year, you will also save on the cost of these.

In addition to this, you will also be paid for the hot water and heat that you generate and use yourself. This payment level varies depending on the type of technology you install in your property.

The Domestic RHI scheme is ideal for those looking to reduce their carbon footprint and CO2 emissions through sustainable technology. Additional incentives are also available for those wishing to install metering and monitoring packages.

Non Domestic Renewable Heat Incentive (RHI)

The Renewable Heat Incentive (RHI) for industrial, commercial, public sector and not-for-profit and community installations opened its doors for applications on Monday 28 November 2011.

If you are interested in applying for support under the scheme you will need to contact Ofgem who are responsible for administering the scheme. More information about how to apply, as well as detailed Guidance documents to support you through this process, is available on their website at Ofgem. Alternatively you can contact their enquiries centre on 0845 200 2122 or by email to RHI.Enquiry@ofgem.gov.uk

Test procedures

For smaller appliances (nominal heat output •300kW13), different test procedures are specified in different countries at present. In future, the UK would like to see these being reconciled into a single, agreed methodology or, failing that, to devise a UK methodology for use in connection with the RHI and will be taking steps to achieve this. Pending this, non-harmonised standard EN303-5 provides a framework15. It is recognised that results from the different emission test methodologies applied under EN303-5 can produce significantly different results. However, it is the Government’s view that all boilers tested to meet the 30/150 emission limits by any of the methodologies will be of a good quality such as will ensure that PM and NOx limits achieved are very substantially better than those secured under the Clean Air Act fireplace exemption arrangements.

RHI-ecs must be in English or be accompanied by an appropriate translation, and must contain the following:

a) The name of the test house and its official logo
b) The organisation with which the test house was accredited at the time of testing, or by no later than 1 October 2012, in accordance with ISO 17025 for the required tests, and the accreditation number
c) The name, model, manufacturer and output of the appliance(s) tested, and of any other appliance in the same ‘family’ judged by the test house (in accordance with this note) to have equivalent emissions without individual testing; and a statement whether or not this is a manually stoked, natural draught boiler (that is without a fan providing forced or induced draught)
d) The test fuel(s) used, as defined by EN303-5 or EN14961 as appropriate, and, based on these tests, the range of fuels which can be used in compliance with the emission limits for particulate matter and oxides of nitrogen in paragraph h). The list of compliant fuels must be described using the classification in EN14961
e) A statement that tests were conducted:

• for smaller appliances to EN303-5 (including measurement of condensable PM in cases specified by footnote 5);
• for larger appliances to EN 14792:2005 and either EN 13284-1:2002 or ISO 9096:2003, with the duration and averaging of test results in accordance with paragraph 6.2.
f) A declaration that the product tested was a production sample and is fully representative of the current production
g) A declaration that the appliance was tested at ≥85% of its rated output
h) A declaration that those tests showed that emissions were no greater than 30g/GJ total particulate matter and 150g/GJ oxides of nitrogen
i) The actual measured emissions of total particulate matter and oxides of nitrogen
j) The name and signature of the person authorised to issue the certificate
k) The date of issue of the certificate
l) A certificate reference number for quoting in any correspondence
