A Cafe and Restaurant Owner's Guide to Smart Meters

For any cafe or restaurant owner, managing operational costs is a constant battle. Alongside ingredients and staff wages, energy is one of the biggest and most volatile expenses. A busy kitchen, constant refrigeration, and a welcoming dining space all consume a significant amount of gas and electricity. Whilst you can’t serve customers in the dark, you can get much smarter about how you manage your energy consumption - and a smart meter is the key.

This guide explains what a business smart meter is, how the data it provides can lead to real savings for your hospitality business, and why an upcoming change in the UK energy market makes getting one more urgent than ever.

What Is a Business Smart Meter?

A business smart meter is a digital device that automatically records your gas and electricity use and sends the readings directly to your energy supplier. This puts an end to estimated bills, ensuring you only pay for what you actually use. Unlike a traditional meter that needs to be read manually, a smart meter provides a continuous, accurate record of your consumption.

The current generation of meters, known as SMETS2, are designed to stay ‘smart’ even when you switch suppliers. This is a crucial feature for any business looking to get the best deal, a process we cover in our guide, Switching Business Energy Supplier: A Guide. Older, first-generation SMETS1 meters could lose their smart functionality if you moved to a new provider. If you’d like to learn more about the basics, our guide What Is a Business Smart Meter? has all the details.

Your Secret Ingredient: Understanding Half-Hourly Data

The most powerful feature of a smart meter for a business is its ability to record your energy usage in frequent intervals - typically every 30 minutes. This is known as half-hourly data, and it gives you a granular, detailed picture of your energy profile. For a cafe, it can reveal the energy spike from the morning coffee rush, the steady hum of the fridges overnight, and the peak demand during a busy lunch service.

Your supplier is required to give you access to this data, usually through an online portal or app, at no extra cost. By analysing it, you can:

• Spot patterns and anomalies, such as equipment being left on overnight or a faulty freezer using more power than it should.

• Pinpoint your peak demand periods, which is vital for managing costs if you are on a time-of-use tariff.

• Deduce the consumption of major appliances by observing the impact on your usage when they are switched on and off.

This level of insight is the first step towards taking control of your energy bills. For more on this topic, see our guide to Half Hourly Metering.

How Data Turns Into Sterling: Acting on Your Insights

Once you understand when and where you’re using the most energy, you can take targeted action to reduce waste and improve efficiency. A typical pub or restaurant could save between 30-70% on energy bills by implementing some simple changes.

In the Kitchen

Your kitchen is likely the most energy-intensive part of your business. Refrigeration can be a major cost, so ensure your fridges are set correctly - the Food Standards Agency advises 5°C or below. Regularly defrosting freezers and cleaning the seals on fridge and freezer doors will also improve their efficiency. For cooking equipment, minimise pre-heating times where possible and label switches so staff only turn on what’s needed. Don’t forget maintenance; a regular service for equipment like your ventilation system can increase its efficiency by as much as 50%.

In the Dining Area

Simple changes out front can also have a big impact. Switching to LED bulbs can cut your lighting energy costs by up to 90%, and installing motion sensors in toilets and stock rooms means you’re never paying to light an empty space. When it comes to heating, even a 1°C reduction on the thermostat can lower your heating bill by 7%. Use timers and thermostats to ensure your heating and air conditioning aren’t running at full tilt when the premises are empty.

The Tariff Question: Unlocking Smart Meter Savings

A smart meter is often a requirement for accessing certain business energy tariffs, particularly time-of-use (ToU) tariffs. These tariffs charge different prices for electricity at different times of the day, with higher rates during peak hours (usually late afternoon and early evening) and cheaper rates overnight and at other off-peak times.

For a cafe or restaurant, a ToU tariff can offer significant savings if you can shift energy-heavy tasks to the cheaper, off-peak periods. For example, you could:

• Run the high-powered dishwasher overnight.

• Schedule intensive food prep, like batch cooking or baking, for quieter, off-peak times of the day.

• Charge any electric vehicles used for deliveries during the cheapest overnight hours.

Some suppliers have created specific tariffs to take advantage of this. For example, Octopus Energy’s ‘Shape Shifters’ tariff uses smart meter data to offer 21 hours of cheaper electricity every day, rewarding businesses that can shift their consumption away from the peak 4pm-7pm window.

Why This Matters Now: The UK’s Smart Meter Deadlines

Beyond the immediate cost savings, there is a compelling regulatory reason to get a smart meter now. The UK’s energy market is undergoing a fundamental change called Market-wide Half-Hourly Settlement (MHHS). This is a major programme mandated by the regulator, Ofgem, which will require all business electricity usage to be settled on a half-hourly basis.

The transition to MHHS is already underway and is expected to be completed by May 2027. After this point, it is expected that any business will need a smart meter capable of providing half-hourly data to get a new fixed-term energy contract. This makes installing a smart meter less of an option and more of a necessity for securing your future energy supply and managing your costs effectively.

The goal of MHHS is to create a more flexible and efficient energy system that can better support the UK’s transition to Net Zero. By matching consumption to generation more accurately, it encourages energy use when renewable power is plentiful and cheaper. Ofgem estimates the programme will deliver net benefits to consumers of between £1.5 billion and £4.5 billion by 2045.

How Do I Get a Smart Meter?

For most small businesses, the process is simple and comes at no extra cost. Your first step should be to contact your current energy supplier, who is responsible for the installation. Many have a dedicated page on their website where you can request one.

Eligibility for a free installation usually depends on your business size, with those employing fewer than 10 people generally qualifying. If you rent your cafe or restaurant, you can still request a smart meter as long as you are the one responsible for paying the energy bills. It is always wise to check your lease agreement first, but the meter itself belongs to the supplier, not the property.

The installation itself typically takes around two hours per meter (one for gas, one for electricity). Your supplier will work with you to arrange a time that causes the least disruption to your service.

Conclusion: Your Meter Is a Management Tool

In the competitive hospitality industry, every pound saved on overheads goes straight to your bottom line. A smart meter is no longer just a device for billing; it’s a powerful business intelligence tool. It gives you the granular data you need to understand your energy consumption, identify waste, and make informed decisions that cut costs.

With the Market-wide Half-Hourly Settlement deadline approaching, the question is not if you should get a smart meter, but how soon you can get one installed. It is a crucial step in future-proofing your cafe or restaurant, controlling a key operational cost, and preparing for the next generation of the UK’s energy market.
