Energy Efficiency Standards and Penalties in Wales

Being a renter in Wales means you have rights when a property is not energy efficient. This guide explains what landlords must provide, how energy performance is measured, and what penalties can apply if a privately rented home does not meet the minimum energy efficiency standards. It uses plain language for tenants and renters, shows practical steps to collect evidence, how to contact your landlord, and when to involve local authorities or the First-tier Tribunal (Property Chamber). If you are cold, paying high energy bills, or worried your landlord is not complying, this page tells you what forms and official sources to check and how to make a complaint in Wales.

What landlords must do

Landlords who let privately rented properties in Wales must meet the minimum energy efficiency requirements for the private rented sector and normally must provide a valid Energy Performance Certificate (EPC) to prospective renters and when asked. Failure to comply can mean civil penalties or enforcement action by the local authority or referral to the First-tier Tribunal (Property Chamber). ^[1]

Official forms and documents tenants may see

• Energy Performance Certificate (EPC) — not a numbered form; ask your landlord to provide the EPC document or digital certificate as evidence when you move in or request it.
• MEES exemption declaration or application — if a landlord claims an exemption, request to see the exemption application or decision document so you can check its validity.
• Tribunal or court application guidance — if a dispute proceeds, official tribunal application guidance explains how a tenant or landlord starts a claim.

Penalties and enforcement

If a landlord breaches energy efficiency rules, local authorities can issue civil penalties and enforcement notices, and in some cases the matter can be decided by the First-tier Tribunal (Property Chamber). Penalties for non-compliance can be substantial, and failure to respond to enforcement can affect a landlord’s legal position. ^[1][3]

How to report non-compliance

If you think your landlord is not meeting energy efficiency duties, follow clear steps to protect yourself and build the best case possible.

1. Gather evidence: get a copy of the EPC, take dated photos of the problem, and save messages or letters between you and the landlord.
2. Contact your landlord in writing and set a reasonable deadline (for example, ask for a reply within 14 days) explaining the issue and what you want fixed.
3. If the landlord does not act, file a complaint with your local authority’s environmental health or private sector housing team and include the evidence you gathered.
4. If enforcement fails, consider applying to the First-tier Tribunal (Property Chamber) or seeking legal advice on next steps.

FAQ

What is an EPC and why does it matter for renters?

An Energy Performance Certificate (EPC) rates the property’s energy efficiency and helps you understand likely energy costs; landlords must provide it on request and it is key evidence if you report non-compliance. ^[2]

Can I withhold rent if my home is very cold because of poor efficiency?

Generally you should not withhold rent; instead, raise the issue in writing, report to the local authority if necessary, and seek legal advice before taking rent-withholding measures.

Who enforces energy efficiency rules in Wales?

Local authorities enforce minimum energy efficiency standards and the First-tier Tribunal (Property Chamber) can hear related disputes; both routes are part of the official enforcement framework. ^[3]

How-To

1. Find and save the property’s EPC and any written communications with the landlord as evidence.
2. Write to the landlord explaining the issue, what outcome you want, and a clear timescale for response.
3. If there is no satisfactory response, submit a complaint to your local authority’s housing or environmental health team with supporting documents.
4. If enforcement does not resolve the issue, apply to the First-tier Tribunal (Property Chamber) or get regulated legal advice.
