Energy Price Cap Cut: What London Landlords Need to Know and Do Now

Ofgem’s Energy Price Cap Reduction: The Essentials

On 1 April 2026, Ofgem is set to reduce the energy price cap by 7%, translating into typical annual dual fuel bill savings of approximately £117 for households on default tariffs. This cap limits what energy suppliers can charge on standard variable tariffs, but fixed-rate deals may offer even better value.

For London landlords, this update arrives amid ongoing cost-of-living challenges affecting tenants and the rental market broadly. While there is no legal requirement to switch or adjust tariffs on behalf of tenants, landlords and letting agents have a practical role in helping tenants navigate these changes.

Why This Matters to Landlords

Energy costs are a significant part of tenants' outgoings, influencing their ability to pay rent on time and maintain tenancy stability. Lower bills can ease financial strain, reducing arrears risk. However, energy price volatility remains a concern throughout 2026 and beyond.

Landlords with different portfolios face varied implications:

• Single-unit landlords may find tenant retention easier if they actively support energy cost management.
• HMO landlords should consider collective advice or bulk energy purchasing strategies where applicable.
• Portfolio landlords can standardise tenant communications and implement property-wide efficiency improvements.
• Accidental landlords might benefit from straightforward guidance to pass on to their tenants without extensive operational changes.

Practical Steps for Landlords Starting Now

1. Inform Tenants Promptly: Communicate the energy price cap reduction clearly and advise tenants to review their current tariffs. Highlight that fixed deals below the cap may offer greater savings.

2. Encourage Tariff Comparison: Direct tenants to reputable comparison sites or energy advice services. Consider including links or resources in tenancy welcome packs or newsletters.

3. Promote Energy Efficiency: Simple measures such as draught-proofing, LED lighting, and efficient heating controls can reduce consumption. Share tailored tips for your property types.

4. Prepare for Tenant Queries: Train your property managers or letting agents to handle questions on energy bills and tariff options confidently.

5. Monitor Market Developments: Energy prices can fluctuate; stay updated on Ofgem announcements and market trends to advise tenants and adjust strategies accordingly.

6. Review Property Energy Performance: Use this opportunity to assess EPC ratings and plan upgrades that could enhance energy efficiency and appeal to cost-conscious renters.

Benchmarking and Local Context

While the £117 saving is a national average, London tenants often face higher energy costs due to older housing stock and larger properties. Landlords should benchmark savings locally by:

• Checking average consumption figures for their property types.
• Consulting local energy advice centres or councils for tailored guidance.

Next Conversations to Schedule

• With tenants: Discuss current energy tariffs and any support they need.
• With letting agents: Align on communication strategies and energy advice resources.
• With maintenance teams: Plan energy efficiency inspections or improvements.
