Share the Knowledge (and the Savings)

The UK has just recorded its hottest June day on record: 36.1°C.

For most people, that means fans, cold drinks, and a lot of complaining about the heat. For always-on businesses, it means something much more expensive.

Think pubs. Hotels. Gyms. Restaurants. Commercial sites that cannot simply switch things off and wait for temperatures to drop.

When the heat spikes:

• HVAC systems work harder and for longer
• Refrigeration has to fight ambient temperatures all day
• Ventilation loads rise as buildings try to stay usable for customers and staff
• Grid demand surges as thousands of sites cool at the same time

That pressure is not theoretical either. NESO has recently issued routine system warnings as electricity demand tightens under these conditions. In plain English: when the country gets hotter, the system gets stressed, and businesses feel it on the bill.

Why This Heatwave Hits Margins Twice

Cooling is one of the biggest hidden drivers of summer energy spend.

It rarely shows up as a single obvious problem. Instead, it creeps in through longer runtimes, inefficient setpoints, aging plant, poor controls, doors opening constantly, and equipment battling against heat gain hour after hour.

Now layer that on top of a market that is already sensitive.

Since the April 2026 TNUoS fee hikes, many businesses have already been feeling the pressure of higher grid-related costs. So this heatwave becomes double-trouble for margins:

• higher electricity use on site
• more strain during peak demand periods
• less room to absorb avoidable waste

If your business is always on, hot weather is not just uncomfortable. It is expensive.

Don’t Just Suffer the Bill

The businesses that handle summer best are usually not the ones with the biggest plant rooms. They are the ones that understand their energy profile.

That means knowing:

• where cooling is running inefficiently
• which assets are costing more than they should
• whether controls and schedules still make sense
• what can be fixed now before the next heat spike lands

This is exactly where our Discovery Assessment and Roadmap come in.

We help businesses pinpoint where cooling and broader energy use are draining margin, then map out practical next steps to reduce waste and improve resilience. No fluff. No guesswork. Just a clearer picture of what is happening and what to do next.

Don’t let one hot month undo your margins for the quarter.

If you run a pub, hotel, gym, restaurant, or other high-usage commercial site, now is the time to take a proper look at your energy setup before the next spike in temperature and demand.
