Rising energy bills, inflation and higher wage costs continue to put pressure on UK business margins. Whether you run a micro-business from home or employ staff in commercial premises, keeping overheads under control is essential. The good news is that many cost-cutting measures also reduce your environmental impact, so saving money and cutting carbon can go hand in hand. Here are practical steps to lower the cost of running your business while making it more sustainable.

Switch to a better energy tariff or generate your own power

Energy remains one of the largest variable costs for many businesses. Although the government’s Energy Bill Relief Scheme ended in 2023, businesses can still protect themselves by reviewing their contract regularly and comparing tariffs. Unlike domestic customers, businesses are not covered by Ofgem’s price cap, so shopping around is especially important.

Start by checking when your current contract ends and what unit rates you are paying for electricity and gas. A fixed-rate contract can help with budgeting if prices rise, while a flexible or variable tariff may suit businesses that can shift energy use away from peak times. If you use a broker, make sure they are transparent about commissions and confirm the final price in writing.

On-site renewable generation is another option worth exploring. Installing solar panels, a small wind turbine or a battery storage system requires upfront investment, but falling installation costs and the potential to sell surplus power back to the grid can improve the payback period. For businesses that cannot install generation equipment, a green tariff backed by renewable energy guarantees of origin can still support your sustainability goals.

Invest in energy-efficient equipment and building improvements

Upgrading equipment is one of the fastest ways to cut ongoing energy costs. LED lighting typically uses up to 80 per cent less electricity than traditional bulbs and lasts far longer. Modern heating and cooling systems, including heat pumps, are much more efficient than older electric or gas systems, especially when paired with good insulation and draught-proofing.

Look for energy labels when buying office appliances such as fridges, printers and computers. Devices with higher ratings cost less to run and may qualify for tax relief. The Annual Investment Allowance and full expensing rules allow many UK businesses to deduct the full cost of qualifying plant and machinery from profits before tax, which can make efficiency upgrades more affordable. Check our overview of business tax reliefs to see what applies to your situation.

Simple building improvements also help. Sealing gaps around windows and doors, adding insulation, fitting automatic light sensors and installing a smart meter can all reduce waste. A smart meter gives accurate billing and helps you spot where energy is being used so you can target further savings.

Reduce water usage

Water bills are easy to overlook, yet reducing consumption can cut costs and environmental impact. If your premises are metered, you pay for every litre, so small changes add up quickly. Fit low-flow taps, aerators and dual-flush toilets, and fix leaks promptly. A dripping tap can waste thousands of litres a year.

Consider harvesting rainwater for outdoor use or irrigation if you have grounds, and reuse greywater where regulations allow. In hospitality, only serving water on request is now common practice and reduces both water use and the energy needed to chill it. If you are in England or Scotland, you can choose your water retailer, so it is worth comparing tariffs and services in the same way you would for energy.

Recycle, reuse and cut waste

Waste disposal is expensive, and landfill taxes continue to rise. Applying the waste hierarchy—reduce, reuse, recycle, recover, dispose—can lower costs and keep your business ahead of regulations such as the Plastic Packaging Tax and extended producer responsibility reforms.

Start by reducing packaging and single-use items. Reuse incoming packaging for outgoing shipments, set up clearly labelled recycling stations, and donate or sell surplus stock rather than throwing it away. Food businesses can partner with redistribution apps or charities to cut food waste. WRAP (Waste and Resources Action Programme) offers free tools and guidance for businesses, and some local authorities provide grants for waste reduction projects.

Embrace flexible and hybrid working

Allowing staff to work from home, even part of the week, can reduce the office space, furniture, equipment and utilities you need. Many businesses have moved to smaller premises with hot-desking, cutting rent and business rates. Employees may also use their own equipment, though you should still provide what is needed for health, safety and data security.

Since April 2024, employees in Great Britain have had the right to request flexible working from their first day in a job. A well-planned hybrid policy can improve retention, reduce commuting costs and lower your carbon footprint. Read more about flexible working arrangements and how to implement them fairly.

Audit and review your spending

Regular financial reviews are the foundation of good cost control. Set aside time each quarter to go through every line of expenditure and ask whether it is still necessary. Cancel unused subscriptions, renegotiate supplier contracts, and get at least three quotes for recurring services such as insurance, IT support and accountancy.

Use cloud accounting software to track spending in real time and compare actual figures against your budget. Benchmark your costs against industry averages where possible, and involve your team—employees often spot waste and inefficiency that managers miss. If cash flow is tight, prioritise spending that directly generates revenue or protects essential operations.

Cutting costs does not mean cutting corners. By reviewing your energy, water, waste and workspace costs regularly, you can build a leaner, more resilient business that is better prepared for future price rises.
