The information below is based on the original consultation document published in February. On October 20th, within the Spending Review, the Government announced that the Renewable Heat Incentive has the green light and will begin in April 2011. However, it will be reduced in scope by 20% as it will now be paid for by the Treasury, instead of through a levy on energy bills, as originally planned. This will have an impact on the current information, and we await the Government's response to the consultation before we can confirm how the scheme will have changed. The Governments response is anticipated by the end of the year. (Dept of Energy & Climate Change)

The Renewable Heat Incentive (RHI) pays the property owner for the renewable heat generated within the property, where certain eligible technologies have been installed by a certified installer.

The RHI is a fixed annual payment for the renewable heat you generate yourself. The incentive payment and the money you save on your energy bills, will off-set the cost of installing the renewable system.

The tariff payments will be calculated by multiplying the proposed tariff per kWh by the amount of heat output of the system. This may be measured or deemed (which means a calculated estimate of the heat output).

Although very similar to the Feed-In Tariffs, there are two differences due to the fact that pretty much every single property in the UK generates its own heat from a gas or oil boiler. Firstly, there is no ‘National Grid for Heat’ and so importing and exporting heat is not relevant. Secondly, it will be paid for by the Treasury not by energy users.

To qualify:

*install a renewable heat systems in your property such as solar thermal panels, heat pumps or a biomass (wood burning) boiler
*estimate of how much heat your renewable energy systems will produce
*register in April 2011 and get paid a fixed amount annually, based on the estimated heat output

Benefits

*Cut the cost of your current energy bill
By installing renewable heat equipment, you will get paid for the heat you generate. Apart from the cost of electricity to power a heat pump or wood chip/pellets for a biomass boiler, the RHI is structured so that these costs are reduced or approximately the same as the payments you receive. The average home is expected to make a net profit of £600!

*You won't be affected by fuel price changes as badly
We have all seen our utility bills rising and the prediction is, that they will continue to do so. Renewable energy means you will only rely on a small amount of this purchased energy from utility companies, as all the systems rely on electricity or some other fuel (e.g. wood) to run.

*Help the environment
We generate 99% of all the heat we need from oil, gas fuel or electricity power stations. Only 1% comes from renewable sources. The aim of the Renewable Heat Incentive, is to get 12% of the UK's heat generated from renewable sources by 2020.

 The Feed in Tariff or FITs scheme guarantees a minimum payment for all electricity generated by the system, as well as a separate payment for the electricity exported to grid. These payments are in addition to the bill savings made by using the electricity generated on-site.
Once you have a microgeneration technology installed you should experience a monthly reduction in your electricity bill and then receive an income from your Feed-in tariff provider. However, if you have taken out a loan to pay for the installation you will have to make monthly repayments to your loan company.
Feed-in tariffs are designed so that the average monthly income from your installation will be significantly greater than your monthly loan repayment (with a 25 year loan).

As a registered Carbon Trust loans supplier, Wolf Passive Homes can guide you through the process of assessing, installing and funding new energy saving equipment for your project.

Borrow £3,000 to £100,000 at 0% interest
0% business loans of £3,000 - £100,000 are available from the Carbon Trust to help organisations finance and invest in energy saving projects.

Why a 0% business loan makes business sense:
New, more efficient equipment will lower energy bills while, the loan repayments are calculated to be offset by the energy savings and therefore, the loan is designed to pay for itself. 

Through our partnering initiative and our highly qualified professional teams of installers, we can guide you through all the important decisions associated with the installation of renewables and energy-efficient products, from the initial survey right through to completion.

All our systems and products are of high quality at cost-effective prices, and have been tried and tested over many years.

Installations are carried out with a minimum of disruption and to a high industry standard, and depending on the system or product you wish to  install, will take as little as 1 day up to about a week in most cases.

MVHR - our installers are highly qualified heating & ventilation engineers that are HVCA registered. They receive additional training by the manufacturer, to ensure full understanding of our MVHR units. Installations are carried out to a high industry standard that will ensure the MVHR unit works to its maximum efficiency and design.

Windows & Doors - we only use FENSA registered installers. To give you peace of mind, our hassle-free self-certified installations do not require planning permission approval.

Solar - our professional MCS registered installers have the background experience in heating & plumbing to ensure the panels installed, deliver the energy you require and qualify for the paid Government tariffs.

Electrical - our professional MCS registered installers are NAPIT or NICEIC accredited.

Biomass - our professional MCS registered installers are also HETAS accredited. To give you peace of mind, our self-certified installers will give you a Certificate of Compliance which means you do not require building control approval.

Large Developments & Commercial Projects - whatever the project and system solution, we have the expertise and installers to offer you the advice, guidance and assessment to ensure the right solution is installed and achieves the energy-savings the products are designed to deliver.

To achieve the best performance and comfort from an MVHR system, the detail of the installation is very important. Where and how ducting is installed, the precise positioning of intake and exhausts and where insulation is used will all affect the efficiency of heat recovery. Correct design of acoustic attenuation will mean an acoustically imperceptible system which is comfortable to live with. Our technical team are skilled designers and use specialist CAD software to create ducting systems layouts, which are both efficient and quiet.  

We use highly qualified installers throughout the installation process to ensure the system is installed to deliver the fresh, warm or cool air at maximum efficiency.

Airtightness Testing is a simple and effective way to maximise your EPC (Energy Performance Certificate) rating and ensures you achieve a high quality build. It is now a mandatory test in order to minimise thermal bridging and air leakage in the fabric of the building.

For any new build project, dwellings require an Airtightness Test to prove compliance with Part L1 of the Building Regulations. Airtightness Testing will identify air leakage paths using special equipment. Any air leakage will comprise the comfort within a building and cause heat loss, thereby increasing your heating bills.

Airtightness Testing quite often uncovers air leakage paths via skirting boards, loft hatches, floor-to-wall & wall-to-ceiling joints, around windows, waste pipes and extractor fans. Eliminating air leakage paths can help a developer/builder to determine whether the dwelling has been built to a high standard and also improves the overall energy efficiency - hence, a higher rating on the EPC for the dwelling and therefore, enhanced saleability.

Standard Assessment Procedure (SAP) calculations are a mandatory requirement for any new build dwelling. SAP is used to show compliance with Part L of the Building Regulations and is applied at the design stage of the build process and is submitted to Building Control.

SAP calculates the energy cost and carbon emissions generated to heat, light, ventilate and provide hot water to a building. A SAP calculation at the design stage, produces a Projected Energy Assessment (PEA) which details how much energy a new home will use. This is translated into a more user-friendly Energy Performance Certificate (EPC) once the building has been constructed. The EPC is a certificate which summarizes the SAP assessment and is used when marketing the property for sale.

The new build EPC (Energy Perforamce Certificate) is a mandatory certificate which summarizes the SAP assessment and is used when marketing the property for sale.

Building Control will not issue a completion certificate until a valid new build EPC has been produced by a certified Energy Assessor.

New Build Simplified Building Energy Model (SBEM) Calculations are a mandatory requirement for any heated, new commercial building exceeding 50m2 floor area.

SBEM calculates the energy cost and carbon emissions generated to heat, light, ventilate, cool and provide hot water to a building. SBEM calculations are also used to show compliance with Part L of the Building Regulations, and should be applied from the design stage of the build process.

As with residential buildings, Building Control will not issue a completion certificate until a valid EPC has been produced by a certified Energy Assessor.

The Environment Agency has found that 20% of the UK's water is consumed domestically, with 50% of this used for flushing WC's and washing. Therefore the development of practical ways to reduce water consumption is important.

On the 6th April 2010, Part G of the building regulations included the mandatory need for a water efficiency calculation to be carried out for every new dwelling.

A calculation is required to show the potential consumption of wholesome water per person per day. The calculation is based on fixtures and fittings in a dwelling and also any greywater or rainwater harvesting technologies. Each dwelling is required to have a maximum consumption of 125 litres/person/day which is equivalent to the BRE's Code for Sustainable Homes level 1 standard.

The Code for Sustainable Homes gives an indication of the overall sustainability of a dwelling. The CSHs differs from SAP calculations by taking into account the type and sustainability across various elements, such as:

- Materials used to build the dwelling
- Water consumption
- Refuse waste
- Recycling
- Builders waste
- Construction management and the site ecology

Plans and proposals are assessed at the design stage to give you an indiction of the code level you can achieve and adjustments you can make. This is followed up by a post construction review and the issue of a Code Completion Certificate by the BRE.

Most planning authorities require a survey detailing what percentage of the energy demand for a new building is provided by using renewable energy sources.

Most authorities stipulate that at least 10% of the energy demand should be sourced from alternative energy such as solar panels, Biomass and wind turbines.

The Renewable Statement uses the design stage SAP calculations to evaluate the energy demand and the source of renewable energy.
