Your guide to the proposals to increase the Minimum Energy Efficiency Standards

8 November 2021

The Minimum Energy Performance of Buildings bill to increase the minimum energy efficiency standards for private rented properties to EPC Band C on new tenancies by 2028 is awaiting a second reading in the House of Lords - while an EPC action plan has been published to support these recommendations.

The government wants to raise the minimum energy efficiency standards to EPC Band C by 2025 for new tenancies in private rented homes and by 2028 for all tenancies to improve the overall energy performance of the private rented sector in England and Wales.

A consultation on the new EPC proposals

The consultation on the proposals ran until 8 January 2021 and they feature in the Minimum Energy Performance of Buildings bill, which is now awaiting its second reading in the House of Lords. 

In line with the consultation, the government has announced a plan of action for how to improve the use and performance of Energy Performance Certificates (EPCs), which includes updating the Energy Performance of Buildings (England and Wales) Regulations 2012 (EPB Regulations) in 2022.

Current energy efficiency in homes

UK housing stock is generally older than in the rest of Europe, according to the consultation document, and “the potential for improvement in the energy performance is considerable”.

Privately rented properties, which make up 20% of the housing stock, are among the least energy efficient, “costing over £6bn in energy bills in 2018 and producing GHG emissions of around 11 megatonnes of carbon dioxide equivalent a year”.

Improving energy efficiency in homes

Improving the energy performance of these homes is therefore a vital part of the government’s strategy to meet its greenhouse gas emissions target of net zero by 2050. More energy efficient homes will also help mitigate against the rising cost of energy during the energy crisis.

The English Housing Survey 2019-2020 shows evidence that the sector is already moving in the right direction - the number of private rented homes in EPC bands A to C in 2019 was up 13 percent versus 2009, with 38 percent of all private rental homes falling into this category.

Last year, it was estimated that 58 percent of UK homes would be affected by the proposed new standards and the Office of National Statistics estimates that it would cost each applicable private rented property £7,646 to move into Band C, in line with the proposals.

Increasing the minimum standards

The core proposal is raising the minimum energy efficiency standards for to EPC Band C, improving the energy performance of privately rented homes in England and Wales.

These bands are based on the total annual cost of energy to heat and light a property, running from A to B, with properties rated A being the most energy efficient. Under the current regulations, the minimum energy efficiency rating for privately rented properties is EPC Band E.

There are currently 3.2 million PRS properties in England and Wales with an EPC rating of D or below.

Using a phased introduction for new standards

The government is proposing using a phased introduction of the new standards, which means that they would apply to new tenancies from 1 April 2025 and all tenancies by 1 April 2028.

This would limit disruption to landlords and tenants, allow more time for landlords to plan and save for improvements, and encourage a “whole house” approach to improvements.

Increasing the maximum investment cap

Under the current regulations, landlords of properties in EPC Band F or G are required to self-fund energy efficiency improvements, as recommended on the EPC, up to a cap of £3,500.

There are some third-party funding options available. However, the consultation document notes that “improving PRS properties to EPC Band C will require greater investment”, so the government wants to increase the cap to £10,000.

Government modelling indicates that, on average, most landlords would need to spend £4,700 to bring their properties up to EPC Band C.

Legislating for a “fabric first” approach

A “fabric first” approach to energy efficiency prioritises improving the fabric efficiency of a building - for example, its insulation - before making improvements to its heat and electricity generation.

In addition to cost-effectiveness, a fabric first approach is used to inform recommendations for improvements listed on an EPC. This means that improvements are listed in the following order:

1. Insulation
2. Heating and hot water
3. Windows and doors upgrades
4. Electricity generation measures

In practice, however, landlords can make the recommended improvements in any order, as long as they are complying with the recommendations.

The government is considering ways in which to encourage landlords to take a fabric first approach, including whether or not this should be a requirement under the regulations.

The EPC plan of action

A list of 35 actions were highlighted in total from the EPC consultation launched in July 2018, with three top priorities:

  • The system needs to produce "accurate, reliable, and trusted EPCs" so they can be relied on to set up incentives and support the other financial implications of improving energy efficiency in homes
  • Consumers need to be engaged and policies created to encourage homes to move to the proposed EPC band C
  • Data infrastructure improvements should be made to ensure EPCs can be used in decision making on improving energy efficiency in homes

The action plan shares that a second consultation is being prepared to progress some of the key regulatory actions with amendments to the EPB Regulations in 2022. Topics that will be discussed include:

  • Using and accessing data to improve the audit of EPCs
  • Considering revising penalty rates, how to ensure compliance, and enforcement
  • Improving oversight and accountability across the EPC system
