Wandsworth Council in London has launched a firm initiative targeting rental properties that fail to meet basic energy efficiency standards. The council has identified over 550 privately rented homes with EPC (Energy Performance Certificate) ratings of F or G—levels that fall below the legal minimum set out in the Minimum Energy Efficiency Standards (MEES) Regulations. Landlords who do not comply risk financial penalties of up to £5,000, signalling that the borough is serious about improving living conditions and reducing carbon emissions.
Since the crackdown began, council officers have contacted more than 150 landlords to conduct compliance checks. This has already led to five financial penalties being issued and, according to the council, a “marked increase” in landlords taking proactive steps to upgrade their properties. The message is clear: landlords cannot ignore the legal standards for energy efficiency without consequences.
Case Study: Battersea Property Gets an Upgrade
A notable example comes from a property in Battersea, which was initially let with a G-rated EPC, far below the legal requirement. Following intervention by the council, the managing agents installed roof insulation to improve the property’s energy efficiency. Initially, the agents argued that certain upgrades, such as a new boiler, were the tenant’s responsibility due to the terms of the regulated tenancy. However, the council issued a £4,000 fine for non-compliance, which the landlord subsequently paid.
A follow-up visit confirmed that the insulation had been properly installed above the main living areas, and the tenant reported being “very happy” with the improvements. They noted that the living room now stayed warmer during colder months, demonstrating the tangible benefits of meeting energy efficiency standards.
Why Upgrading EPC Ratings Matters
Upgrading a property from an EPC band G to E can deliver significant benefits. Carbon savings are estimated at around 20–30%, helping the borough meet wider climate targets. For tenants, improvements can mean warmer, more comfortable homes and lower energy bills, reducing financial pressure in an era of rising living costs.
A Wandsworth Council spokesperson commented: “No one should be renting a property that fails to meet even the most basic legal standards for energy efficiency. By taking firm action against non-compliant landlords, we’re not only improving living conditions for tenants but also helping to cut carbon emissions across the borough. This project shows what can be achieved when councils take a proactive, evidence-led approach, and we will continue to hold landlords to account wherever standards fall short.”
The Broader Context
This crackdown is part of a nationwide effort to ensure rental properties meet energy efficiency requirements. MEES regulations were introduced to protect tenants and encourage landlords to invest in property improvements. Properties with low EPC ratings are less energy-efficient, often costing tenants more in heating and cooling while contributing disproportionately to carbon emissions.
For landlords, the financial implications of non-compliance are becoming increasingly serious. Fines can reach up to £5,000 per property, and repeated violations can lead to further action, including restrictions on letting licences. Many landlords are now recognising that investing in energy-efficient upgrades is not only legally required but also financially prudent, as improved EPC ratings can make properties more attractive to prospective tenants and potentially increase rental income.
Looking Ahead
Wandsworth Council has made it clear that this is only the beginning. Officers will continue to carry out inspections and ensure landlords take responsibility for the energy performance of their properties. The borough’s proactive approach demonstrates how local authorities can drive meaningful change in the housing sector, improving both the quality of rental homes and the environmental impact of the housing stock.
For tenants, this initiative offers reassurance that poorly performing properties are being addressed, while landlords are given clear guidance on how to comply with legal standards. By combining enforcement with support for upgrades, councils like Wandsworth are helping to create a fairer, more sustainable rental market.
