Key takeaways
  • The EPC is the only certificate the law requires you to provide to let, and the rating must be E or above unless an exemption is registered.
  • A TM44 report for air conditioning over 12kW must be handed to the incoming tenant.
  • The asbestos register, EICR, gas safety record and fire risk assessment are not conditions of letting, but a tenant’s solicitor will ask for every one.
  • A schedule of condition agreed at the start protects both sides at the end.

Landlords often ask whether there is a certificate they need before letting a commercial unit, in the way a domestic landlord needs a gas safety certificate. There is no single document. There is one hard legal requirement, the EPC, and a set of records that a tenant's solicitor will ask for in the enquiries before exchange. Having them ready is the difference between a letting that completes in weeks and one that drifts for months.

The one you must have: the EPC

Regulation 6 of the Energy Performance of Buildings Regulations requires a valid EPC to be made available to a prospective tenant and given to them when the lease is granted, and the minimum standard means the rating must be E or above. An EPC lasts ten years. If yours is F or G, you need improvement works or a registered exemption before you can lawfully let. Get the assessment early; the recommendation report tells you what the cheapest route to E is.

Also required where it applies: the TM44 report

If the building has air conditioning over 12kW, the most recent TM44 inspection report must be passed to the incoming tenant. See air conditioning inspections.

The ones every tenant’s solicitor asks for

The standard commercial property enquiries ask about every one of these. A missing answer is a delay and usually a price conversation.

  • Asbestos register and management plan for any building built or refurbished before 2000, required under regulation 4. The tenant needs it before any fit-out. See asbestos surveys.
  • Electrical Installation Condition Report for the installation being let, with any remedial works completed. See the EICR page.
  • Gas safety record for any appliances, pipework or flues in or serving the demise. See gas safety.
  • Fire risk assessment for the building and common parts, and the fire strategy. See fire risk assessment.
  • Legionella risk assessment for shared water systems. See legionella.
  • Planning and building regulations approvals for the current use and any alterations.
  • Service and maintenance records for plant the tenant will take on.

The one that protects you: the schedule of condition

A schedule of condition appended to the lease records the state of the premises at the start. Tenants want it to cap their repairing liability; landlords should want it too, because it fixes the baseline for the dilapidations claim at the end and records that the compliance position was sound when the keys changed hands.

Putting the letting pack together

Assemble everything above before marketing, not after an offer. Agents and solicitors move faster with a complete pack, and the questions a tenant cannot get answered are the ones that become retentions or walk-aways. Our guide to landlord responsibilities covers what stays with you after the letting.

Filling the gaps

The free compliance check lists every duty on the property you are letting and gets a quote for each certificate you are missing, in one go.

Frequently asked questions

What certificates do I need to let a commercial property?+
By law, a valid EPC rated E or above, and the TM44 report where air conditioning exceeds 12kW. In practice a tenant’s solicitor will also ask for the asbestos register, the EICR, the gas safety record, the fire risk assessment, the legionella assessment and planning consents.
Do I need a gas safety certificate to let a commercial property?+
There is no equivalent of the domestic landlord’s annual certificate, but the duty to maintain gas appliances applies to whoever controls them and a tenant’s solicitor will ask for the current record. An annual inspection recorded on a CP17 is the recognised standard.
Do I need an EICR to let a commercial property?+
It is not a legal condition of letting, but the installation must be safe under the Electricity at Work Regulations and a current EICR is the evidence every tenant’s solicitor requests.
What EPC rating do I need to let a commercial property?+
E or above. Letting at F or G is unlawful unless a valid exemption is registered on the PRS exemptions register, and penalties reach £150,000 per property.
