The Department of Energy and Climate Change

The Department of Energy and Climate change plays a crucial role in UK energy and environmental policy. This affects customers, too.

Objective and priorities

The DECC’s objective is to “make sure the UK has secure, clean, affordable energy supplies and promote international action to mitigate climate change.”

This objective translates into three main priorities at the Department of Energy and Climate Change:

  • An economic priority: promoting investment in UK energy infrastructure.
  • A consumer priority: assisting consumers in keeping energy bills as low as possible.
  • A global priority: ensure energy security and promote actions to mitigate climate change.

Policies and actions

The Department of Energy and Climate Change implements these priorities through a series of eight policies (some of them with common actions).

Helping households cut their energy bills

With Ofgem (the national energy regulator), the Department for Communities and Local Government, and the Department for Work and Pensions, the DECC’s policy’s objective is threefold:

  • assist households in keeping energy bills down;
  • assist households that are most in need with their energy bills;
  • improve energy supply security in the long term.

Helping households cut their energy bills is implemented through six strategies:



Helping people use less energy

A series of energy efficiency initiatives including the Green Deal (home improvements offset by bill savings), smart meters (real-time energy use information), the Energy Company Obligation (industry subsidy for those in need), the Electricity Demand Reduction Project (incentive assessments), Smarter Heating Controls Research Programme (assess heating control impact on energy use).

Helping households get the best deal

Working with energy companies to accelerate and facilitate switching.

Helping the most vulnerable households

Direct financial help for people eligible for the Warm Home Discount (lower bills for vulnerable households), Winter Fuel Payment (subsidy for pensioners), Cold Weather Payment (subsidy for pensioners during severely cold weather).

Big Energy Saving Network

Extensive outreach programme aimed at vulnerable customers to help them lower energy bills and energy consumption.

Electricity Market Reform

A series of regulatory reforms aimed at reducing household energy bills by 5% to 9% on average between 2016 and 2030.

Securing the UK’s energy supply

Attract investment through the electricity market reform, remove barriers to competition, prepare for energy emergencies, increase energy efficiency, make UK resource recovery more cost-effective, improve energy infrastructure/networks, reduce UK carbon emissions from energy, work at EU level on security of supply.


Increase the use of low-carbon technologies

With the Environmental Agency, the DECC aims to increase the share of renewable and nuclear energy in the UK’s mix and reduce emissions through carbon capture and storage to improve security of supply, reduce greenhouse gas emission and stimulate investments.

Increasing the use of low-carbon technologies is implemented through five strategies:



Low Carbon Energy Innovation

Maximise the impact of UK public sector funding for low-carbon technology through the Low Carbon Innovation Co-Ordination Group.

Exploiting renewable resources

Achieve a 15% share of renewable energy in the UK’s fuel mix by 2020 through the Renewables Obligation (incentives for renewable electricity generation), the Feed-in Tariffs Scheme (paying energy users for small scale low-carbon electricity generation), the Renewable Heat Incentive (paying renewable heat generators for 20 years), the Renewable Heat Premium Payment (subsidies to energy users wanting to invest in renewable heating technologies), the UK Renewable Energy Roadmap (accelerate the use of renewable energies like wind, biomass, etc.), the Renewable Transport Fuel Obligation (imposes a renewable fuel share in companies using large quantities of fuel), the Connect and Manage Network Access regime (efficient connections to the electricity network for new generators).

Investing in nuclear power

Add to the UK’s nuclear generation capacity by 2019 through National Policy Statements (site assessment), Regulatory Justification (benefits and risk analysis), waste and decommissioning arrangements (ensuring operators plan adequately), Generic Design Assessment (assess new nuclear reactor design), electricity network developments, improve UK supply chain competitiveness.

Creating a new carbon capture and storage industry

Support CCS design, construction and operation through capital funding (£1 billion), coordinated research, development and innovation, and work with industry (reduce technology costs, develop supply chain, create storage and improve infrastructure).

Electricity Market Reform

Improve security of supply taking into account climate change targets.


Reducing demand for energy from industry, businesses and the public sector

With the Department for Environment, Food and Rural Affairs, the Committee on Climate Change and the Environmental Agency, the DECC aims to reduce greenhouse gas emissions by acting on industry, business and the public sector energy demand, which are responsible for a significant share of GHG emissions in the UK.

Reducing demand for energy from industry, businesses and the public sector is implemented through 11 strategies:



Carbon Reduction Scheme

Carbon reporting and pricing.

Enhanced Capital Allowances

Tax breaks for energy-saving equipment.

Climate Change Arrangements

Climate Change Levy discount for industries meeting energy efficiency improvement targets.

EU Emissions Trading System

Financial incentives to reduce emissions through GHG pricing.

Using evidence and analysis to inform energy and climate change policies

With the Committee on Climate Change and the Office of National Statistics, DECC aims to improve policy effectiveness through statistical data on context, options, solutions and impact.

Using evidence and analysis to inform energy and climate change policies is implemented through five strategies:




Economic, technical, social, and trials.

Appraisal of policy options

Identify options with optimal benefits and costs.

Monitoring and evaluation

Evaluate policies to measure impact and inform future policies.

Modelling and analytical projections

Assess potential impact of future policies.


Collect statutory and non-statutory from energy companies to inform policy.


Maintaining energy security

With Ofgem, the DECC aims to improve the UK’s energy system’s capacity as well as its diversity and reliability.

Maintaining energy security is implemented through eight strategies:



Reforming the electricity market

Replace and upgrade the UK’s electricity infrastructure.

Removing barriers to competitive markets

Improve commercial and business development in energy.

Preparing for energy emergencies

Improve energy networks and assets resilience.

Increasing energy efficiency

Lowering energy security risks by reducing demand.

Managing the use and disposal of radioactive and nuclear substances and waste

With Defra, the Nuclear Decommissioning Authority and the Environmental Agency, the DECC’s goal is to control the risks associated with radioactive substances.

Managing the use and disposal of radioactive and nuclear substances and waste is implemented through five strategies:



Waste disposal

Policy framework.

Laws and regulations

Drafting, monitoring and assessing laws and regulations on storage, use and transport of radioactive substances.

Reducing the UK’s greenhouse gas emissions by 80% by 2050

With Defra, the Climate Change Committee and the Environmental Agency, the DECC aims to move to “a more efficient, low-carbon economy”.

Reducing the UK’s greenhouse gas emissions by 80% by 2050 is implemented through four strategies:



Setting national policy and strategy

Setting carbon budgets, informing policy through statistics, using the EU Emissions Trading Scheme.

Reducing the demand for energy

Reducing demand (e.g., smart meters), reducing emissions (e.g., Green Deal), improving energy efficiency (CRC Energy Efficiency Scheme), reducing GHG emissions from transport and agriculture.

Investing in low-carbon technologies

Promoting the use of low-carbon technologies, creating an industry for carbon capture and storage, reducing power sector emissions, reforming the UK electricity market, finding innovation in low-carbon technologies.

Publicly reporting carbon emissions from businesses and the public sector

Providing guidance to businesses and local authorities.


Impact on consumers

An estimated 7% of bills are accounted for by policy decisions, according to Ofgem, but some DECC policies enable consumers to save money.

Positive impacts

  • Energy efficiency initiatives help customers use less electricity and gas. Consequently, their energy bills are lower.
  • The Feed-in Tariff helps customers wishing to produce renewable energy offset the cost of solar panels, for example, since suppliers buy excess electricity.
  • The Green Deal scheme enables customers to improve their home’s energy efficiency through the installation of new equipments whose costs are postponed until they start saving on their energy bills.

Negative impacts

Policies often impose administrative costs on suppliers and these administrative costs tend to be incorporated in energy price increases. Although these policies ultimately help consumers, they raise the end cost of energy.

  • Providing energy efficiency advice requires electricity and gas suppliers to employ and train dedicated staff.
  • Supplier information transparency initiatives, such as the tariff information label, take time and resources to implement.
  • Environmental (e.g., the Feed-in Tariff) and social policies (e.g., helping vulnerable households) impose further costs on energy suppliers since they require administration and often reduce margins.
