Maximum Workplace Temperature UK: What Businesses Need to Know Now

Date Published:

June 9, 2026

If you haven’t heard about the Climate Change Committee’s latest proposals yet, now is a good time to pay attention.

The UK’s Climate Change Committee has recommended introducing a legal maximum workplace temperature. It’s not law yet, but the direction of travel is clear. And for businesses across the UK, that means the time to start thinking about this is now, not when the legislation lands on your desk.

What Is the Climate Change Committee and Why Does It Matter?

The Climate Change Committee (CCC) is an independent body set up under the Climate Change Act 2008. Its job is to advise the UK Government on reducing emissions and helping the country adapt to the effects of a changing climate.

Its latest report, A Well-Adapted UK, covers a wide range of recommendations, but one of the most significant for employers is the call for a maximum workplace temperature law.

The Government hasn’t formally adopted the proposals yet. But early signals suggest there’s genuine political will behind them. Businesses that file this away as someone else’s future problem may find they’ve left themselves very little time to prepare when things do move forward.

What Has the Climate Change Committee Proposed?

The recommendations focus on protecting employees from excessive heat and encouraging businesses to invest properly in workplace cooling. In practical terms, the CCC is calling for:

  • A legal maximum workplace temperature to protect employee health and wellbeing
  • A target indoor temperature range of 16°C to 25°C
  • Greater investment in cooling systems and heat mitigation measures
  • Workplace heat protection policies and business continuity planning
  • Employer-led action to reduce heat-related health risks

None of this comes out of nowhere. UK summers are getting hotter, and heatwaves that once felt unusual are becoming a regular feature of the working year.

Why Excessive Workplace Heat Is a Business Problem

It’s easy to dismiss a hot office as an inconvenience. But the CCC’s report is clear that excessive workplace temperatures carry real consequences for businesses.

When it’s too hot, people struggle to concentrate. Mistakes happen more often. Absence rates go up. In warehouses, manufacturing facilities, and other physical environments, heat also creates genuine safety risks that no employer wants to be accountable for.

Even in office settings, a persistently uncomfortable working environment affects morale. It affects how people feel about coming to work. And in a competitive jobs market, that matters more than ever.

The business case for getting workplace temperature under control is strong. Legislation or not.

What a Maximum Workplace Temperature Law Could Mean for UK Employers

If the CCC’s recommended range of 16°C to 25°C becomes a legal requirement, employers will need to show their workplaces can actually meet it.

That means taking a proper look at your current heating, cooling, and ventilation setup. It means identifying the parts of your building that overheat. It means having the right systems in place, and the policies to back them up.

The businesses that will find this hardest are the ones who leave it too late. As more employers start acting on this, equipment availability tightens, and installation teams get booked up. Getting ahead of that curve makes the whole process a lot less stressful and a lot more cost-effective.

How IRS Can Help Your Business Prepare

This is exactly the kind of challenge we help businesses work through every day.

At Industrial Refrigeration Services, we design, install, and maintain heating, cooling, ventilation, and air conditioning solutions for businesses across the UK. We work with manufacturers, warehouses, healthcare providers, schools, offices, and commercial premises of all shapes and sizes.

Whatever your building looks like, we can help you understand where you stand and what you need to do.

That includes:

  • Workplace temperature assessments to identify where the risks are
  • Design and installation of air conditioning and cooling systems built around your environment
  • Upgrades to existing systems where performance or efficiency isn’t where it needs to be
  • Preventative maintenance programmes to keep everything running reliably throughout the year

We handle the whole process, from the initial assessment right through to installation and ongoing support. You don’t need to coordinate multiple contractors or piece things together yourself.

Act Now, Not Later: Why Early Preparation Makes Sense

Here’s the honest truth: the businesses that act early on this will be in a much stronger position than those that don’t.

Demand for cooling equipment and qualified installation teams will grow as this legislation gains momentum. Lead times will extend. Costs are likely to rise. If you wait until compliance becomes mandatory, you may be making rushed decisions under pressure, which rarely leads to the best outcomes.

Starting now gives you time to assess your situation properly, plan your investment, and get the right solution in place without the stress of a looming deadline.
