Reducing energy intensity is one of the most practical ways for small businesses to protect themselves from rising energy costs, particularly if global energy markets remain unstable because of the ongoing conflict involving Iran. Oil prices have already surged sharply due to disruption in key supply routes such as the Strait of Hormuz, raising concerns about higher inflation and energy bills worldwide.

For many businesses, energy is a significant operating cost. Surveys suggest that two thirds of UK businesses spend between 5 per cent and 20 per cent of their total outgoings on energy, meaning even modest price increases can have a noticeable impact on profitability

One of the most effective responses is to reduce energy intensity, which means using less energy to produce the same level of output. The first step is often to review how energy is actually used within the business. Installing smart meters or carrying out a simple energy audit can reveal waste that may otherwise go unnoticed. For example, heating and lighting frequently remain on outside working hours, particularly in offices and retail premises.

Lighting is usually one of the quickest improvements. Switching to LED lighting and installing motion sensors or automated timers can cut electricity consumption significantly. Many small firms have already taken this step, with research showing that around 69 per cent of SMEs investing in energy efficiency have upgraded their lighting systems.

Heating and insulation are another important area. Poorly insulated buildings lose heat quickly, meaning boilers or electric heating systems must run for longer periods. Improving insulation, installing programmable thermostats, and maintaining heating equipment can all reduce energy demand. Guidance from energy advisers suggests that better heating controls and reduced heat loss are among the most effective workplace efficiency measures.

Businesses can also review equipment and production processes. Older machinery, refrigeration units, and computers often consume significantly more electricity than newer models. Regular maintenance and gradual replacement of inefficient equipment can therefore produce long term savings.

Finally, some businesses are investing in on site renewable energy such as solar panels. While this requires an initial investment, generating electricity directly can reduce reliance on volatile energy markets and provide greater cost stability.

In uncertain times, improving energy efficiency is often the most reliable hedge against rising energy prices. Businesses that reduce their energy intensity not only cut costs today but also strengthen their resilience against future shocks in global energy markets.
