Energy Act 2011

Full text: sources/legislation/uk/2011-energy-act.md

Royal Assent: 18 October 2011 | Citation: c.16 | Extent: England, Wales and Scotland (s.113 NI only; s.114 UK-wide)


What the Act Does

The Energy Act 2011 is a five-part omnibus statute. It creates the Green Deal, a property-linked finance mechanism for home energy efficiency improvements; strengthens security of supply arrangements across electricity, gas, and upstream petroleum; and makes a set of targeted amendments to existing energy legislation on offshore transmission, CCS, nuclear security, and coal authority powers.

It is not a market-restructuring statute in the way the Electricity Act 1989 or Energy Act 2013 were. It adds mechanisms and powers onto the existing framework rather than redesigning it.


Part 1: Energy Efficiency

The Green Deal (Chapter 1, ss.1–41)

The Green Deal is the Act's primary innovation. It creates a finance structure where energy efficiency improvements are paid for through energy bills rather than upfront. The key legal mechanism: once a green deal plan is confirmed, repayment obligations run with the property, not with the individual who commissioned the improvements. When a property changes hands, the new bill payer becomes liable.

Core mechanics:

  • A green deal plan is made by the occupier or owner of a property (the "improver") with a green deal provider.
  • Improvements must be installed by an authorised green deal installer.
  • An authorised energy supplier confirms the plan and adds instalments to the energy bill.
  • The "golden rule" concept (estimated savings must equal or exceed payments) is embedded as a framework regulation requirement, not an absolute statutory rule (s.4(8)–(9)).
  • The plan runs with the property: subsection 1(6) makes the current bill payer liable regardless of who entered the plan, and this applies "irrespective of whether the person referred to in paragraph (a) is the person who entered into the plan" (s.1(7)).
  • Sellers and landlords must disclose green deal plans before sale or letting and ensure buyers/tenants acknowledge the liability (ss.12, 14).

The Secretary of State has broad powers to modify gas and electricity supply and distribution licences to integrate green deal payment collection (ss.17–22). Licence holders can be required to collect payments, remit them to providers, and handle defaults.

Consumer Credit Act 1974 modifications (ss.25–30) carved out green deal finance from standard credit regulation, though most of these amendments were subsequently repealed or omitted from 2014.

The Green Deal scheme was wound down in 2015 following government withdrawal of funding. Chapter 1 remains on the statute book.

Private Rented Sector: England and Wales (Chapter 2, ss.42–53)

The Act creates a mandatory regulatory framework for energy efficiency in the private rented sector. The Secretary of State must make regulations (by 1 April 2018) requiring landlords of domestic properties below a specified energy efficiency threshold to make relevant improvements before letting. This is the legislative basis for what became the MEES (Minimum Energy Efficiency Standards) Regulations.

Separately, regulations must (by 1 April 2016) prevent landlords from unreasonably refusing tenant requests for energy efficiency improvements.

Civil penalties for non-compliance capped at £5,000. Local authorities enforce domestic provisions; local weights and measures authorities enforce non-domestic.

Private Rented Sector: Scotland (Chapter 3, ss.54–65)

Equivalent provisions for Scotland, but with important differences: the powers are permissive ("may make regulations") rather than mandatory duties on Scottish Ministers, and the earliest commencement date is 1 April 2015 rather than 2018/2016. The Scottish framework is devolved.

Carbon Emissions and Home-Heating Costs (Chapter 4, ss.66–72)

Amends the Gas Act 1986 and Electricity Act 1989 to introduce "home-heating cost reduction obligations" as a distinct obligation category alongside carbon emissions reduction obligations (ss.68–69). The "Administrator" concept replaces "the Authority" as the body that determines how individual gas and electricity companies must meet their targets. The Administrator may be the Gas and Electricity Markets Authority, the Secretary of State, or another designated body (s.66 amending s.33BC Gas Act 1986).

The Secretary of State gains a power to set overall home-heating cost reduction targets spanning both sectors via the Utilities Act 2000 s.103A (inserted by s.70). These orders require affirmative parliamentary approval.

Electricity generators were removed from the carbon emissions reduction obligation framework by this Act. Restrictions took effect from 1 January 2013 and 6 April 2014 in stages (see Schedule 1).


Part 2: Security of Energy Supplies

Electricity Supply (Chapter 1, ss.79–80)

The Gas and Electricity Markets Authority must publish an annual electricity security of supply report before 1 September each year (inserting s.47ZA into the Electricity Act 1989). The Secretary of State's annual energy security report must include electricity capacity assessments.

These provisions were the legislative underpinning for GEMA's capacity adequacy assessments that preceded the introduction of the Capacity Market under the Energy Act 2013.

Gas Supply (Chapter 2, s.81)

The Gas and Electricity Markets Authority gains power to direct modifications to the Uniform Network Code for gas supply emergencies. Directions are limited to "market-based modifications": those that reduce the likelihood or severity of emergencies. Commenced on the day the Act was passed.

Upstream Petroleum Infrastructure (Chapter 3, ss.82–91)

Replaces the third-party access regime in the Pipe-lines Act 1962 (ss.10E–10H, which are repealed by Schedule 2). The new framework allows applicants to seek access to upstream petroleum pipelines, oil processing facilities, and gas processing facilities. The OGA (originally the Secretary of State; functions transferred to the Oil and Gas Authority by the Energy Act 2016) may grant access on application or on its own initiative.

Key features: - Access applications made to the owner specifying materials, quantities, and duration. - If owner and applicant cannot agree, OGA may issue an access notice. - OGA may also require compulsory modification of infrastructure to increase capacity (s.84). - False information to OGA is a criminal offence (s.88). - Sections 87A, 87B, 89A, and 89B were inserted by the Energy Act 2016 to add appeal rights and sanction mechanisms consistent with the OGA's wider enforcement framework.

Downstream Gas Processing Facilities (Chapter 4, s.92)

Amends Gas Act 1995 s.12 to transfer third-party access authority over downstream gas processing facilities from the Secretary of State to the Gas and Electricity Markets Authority. Facility owners must publish conditions and run consultation periods.

Special Administration (Chapter 5, ss.93–102)

Creates the energy supply company administration (esc administration) regime, a bespoke insolvency procedure for licensed gas and electricity supply companies. The objective is securing continued supply at the lowest reasonable cost (s.95(1)(a)). The Secretary of State or GEMA may apply to the court; an energy administrator is appointed.

This regime was the precursor model for the supplier of last resort arrangements that became important during the supplier insolvency crisis of 2021–22.

The Secretary of State's powers to modify licence conditions to fund an administration expire eighteen months after commencement (s.98).


Part 3: Measures for Reducing Carbon Emissions (ss.104–114)

A set of targeted provisions:

  • Offshore transmission (s.104): Extends time periods for licence modifications and extends the maximum period for property scheme applications from 7 to 16 years in the offshore electricity transmission regime.
  • Nuclear construction site security (s.105): Extends the Anti-terrorism, Crime and Security Act 2001 regime to nuclear construction sites within 5 kilometres of existing nuclear sites. Commenced on the day of Royal Assent.
  • Decommissioning (s.106): Allows the Secretary of State to agree with other parties on how to exercise decommissioning programme modification powers.
  • CCS abandonment relief (s.107): Inserts ss.30A–30B into the Energy Act 2008 to provide relief from abandonment liabilities for installations converted for CCS demonstration projects.
  • CO2 pipelines (s.108): Introduces compulsory acquisition powers for CO2 pipeline rights via a new s.12A in the Pipe-lines Act 1962.
  • Carbon budgeting (s.109): Reporting requirements on energy efficiency measures' contribution to Climate Change Act 2008 carbon budgets. England and Wales only.
  • Energy efficiency aim (s.110): Requires the Secretary of State to aim to improve the energy efficiency of fuel poverty households. England and Wales only.
  • Transmission charge adjustment (s.111): Extends the deadline for electricity transmission charge adjustment schemes from 2024 to 2034, maintaining support for generators remote from demand.
  • Renewable electricity by National Parks/Broads (s.112): Grants those authorities power to generate and sell renewable electricity.
  • Northern Ireland renewable heat (ss.113–114): Enables Northern Ireland to establish renewable heat incentive schemes. The first UK-wide renewable heat incentive architecture.

Part 4: Coal Authority (ss.115–116)

Grants the Coal Authority power to take action regarding subsidence and water discharge unrelated to coal-mining. Previously the Authority's powers were confined to coal-mining consequences. The new sections (4CA for England and Wales; 4G for Scotland in the Coal Industry Act 1994) allow action where subsidence arises from any cause and where water discharge threatens controlled waters or the water environment. Both sections commenced 26 March 2015.


Part 5: Miscellaneous and General (ss.117–122)

  • s.117: Adds Energy Acts 2008, 2010, and 2011 as sources of transmission licence standard condition modifications.
  • s.118: Removes the Home Energy Conservation Act 1995 from Scotland and Wales; repeals selected provisions of the Sustainable Energy Act 2003 and Housing Act 2004 on energy efficiency reporting.
  • s.119: Allows pre-Act consultations to satisfy Act consultation requirements.
  • s.120–121: Extent and commencement provisions (see canonical file for full detail).

  • Energy Act 2016 transferred upstream petroleum access functions from the Secretary of State to the Oil and Gas Authority, inserting ss.87A, 87B, 89A, 89B into Chapter 3.
  • Smart Meters Act 2018 omitted ss.73(5), (7) and (8) relating to smart meter licence conditions.
  • Renting Homes (Wales) Act 2016 added Welsh standard contracts to the domestic PR property definition in s.42.
  • The MEES Regulations (SI 2015/962) are the secondary legislation required by ss.43 and 49.
  • The Tenants' Energy Efficiency Improvements (England) Regulations 2016 (SI 2016/8) were made under s.46.
  • The Green Deal Finance Company and scheme framework were wound down following the June 2015 budget.

Analytical Notes

Green Deal design problem. The Act's core innovation, repayment through the energy bill rather than secured against the property, created a structural ambiguity. The debt is not technically a property charge but runs with the property through the disclosure and acknowledgment mechanism (ss.12–14). This created conveyancing uncertainty and is likely one factor in the scheme's failure alongside the withdrawal of government incentives. The "golden rule" requirement operates through framework regulations (s.4(8)–(9)) rather than as an absolute statutory threshold, giving the scheme flexibility but also undermining consumer protection relative to what the explanatory notes implied.

Security of supply gap. The annual GEMA electricity supply adequacy report (s.79) was a policy response to concerns about declining capacity margins in the run-up to the Energy Act 2013's Capacity Market. The Act planted the reporting obligation; the EMR created the mechanism.

Upstream petroleum access. The replacement of the 1962 Act regime reflects a consolidation of North Sea access rights into a coherent modern framework. The subsequent transfer to the OGA under the Energy Act 2016 completed the policy trajectory toward an independent regulator with genuine enforcement powers over upstream infrastructure.
