If your building has an air-conditioning system with a total cooling output above 12kW, you likely need a TM44 inspection. That applies to commercial properties across Scotland, just as it does in England and Wales. The regulations don’t make exceptions based on location.
A lot of building owners assume Scotland operates under a different set of rules. It doesn’t. The Energy Performance of Buildings (Scotland) Regulations 2008 brought TM44 requirements into Scottish law, closely following the broader UK framework. So if you’ve been putting this off, thinking it doesn’t apply north of the border, that’s worth revisiting. Here is who the TM44 inspection in Scotland actually covers.
Who Is Required to Get a TM44 Inspection?
The obligation falls on the person responsible for the building. That’s usually the owner or the facilities manager, depending on how the property is managed.
You need a TM44 inspection if:
- Your building has air-conditioning systems with a combined rated output over 12kW
- The system provides comfort cooling, not process cooling.
- The building is non-domestic, such as an office, retail unit, warehouse, or school
Residential properties are generally exempt. Mixed-use buildings can get complicated, though. If part of a property serves a commercial purpose, that section falls under the rules regardless of what the rest of the building is used for. It’s the kind of detail that catches people off guard.
How Often Do Inspections Need to Happen?
Every five years. That’s the standard renewal period for TM44 certificates in Scotland, the same as across the rest of the UK.
Once a certificate expires, you need a new inspection. There’s no grace period built into the regulations. Miss the renewal date, and you’re non-compliant. Some building owners only discover this when a solicitor asks for the certificate during a property transaction, and there isn’t one ready.
That situation is more common than it should be, and it causes real delays at exactly the wrong moment.
What Happens If You Don’t Have One?
Local authorities in Scotland have the power to enforce TM44 compliance. They can issue penalty charge notices for failure to hold a valid certificate or display it correctly.
The fine sits at £300 for not having a certificate. That might not sound like a large amount on its own. The bigger issue tends to come up during property sales or lease negotiations. Buyers and their solicitors check for certificates. Tenants ask questions. A missing TM44 certificate can slow things down considerably or, in some cases, put a deal at risk.
For anyone managing a portfolio of commercial properties across Scotland, tracking inspection expiry dates is one of those tasks that feels routine until it suddenly isn’t.
A Practical First Step
If you’re not sure whether your building qualifies, check the cooling output figure for your air-conditioning units. The manufacturer’s data should show the rated output. If the combined total across all units exceeds 12kW, an inspection is almost certainly required.
Getting it scheduled before a lease renewal, sale, or audit removes the pressure that builds when someone asks for documentation you can’t produce quickly.
