Rising energy bills, inflation and wage costs continue to squeeze UK business margins in 2026. 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. For women founders looking to protect margins and free up cash for growth, the following steps offer a practical starting point to cut business costs and energy use in the UK while making your operation more resilient.
Switch to a better energy tariff or generate your own power
Energy remains one of the largest variable costs for many businesses. The government’s Energy Bill Relief Scheme ended in March 2023, and unlike domestic customers, businesses are not covered by Ofgem’s price cap. This means shopping around is essential. See gov.uk guidance on business energy support for current schemes.
Start by checking when your current contract ends and what unit rates you pay for electricity and gas. A fixed-rate contract helps 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. Installing solar panels or battery storage requires upfront investment, but falling installation costs and the Smart Export Guarantee 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 uses far 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 lets most UK businesses deduct up to £1 million of qualifying plant and machinery expenditure each year, while full expensing allows 100 per cent first-year relief on qualifying new main-rate plant and machinery. See gov.uk guidance on full expensing for eligibility. Read our Allowable Expenses Self Employed UK guide for more detail.
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. In England and Scotland, business customers can choose their water retailer, so compare 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. From April 2025, the standard rate of landfill tax in England and Northern Ireland is £103.70 per tonne, while the lower rate is £3.15 per tonne, according to HM Treasury. Applying the waste hierarchy, reduce, reuse, recycle, recover and dispose, can lower costs and keep your business ahead of regulations.
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.
Manufacturers and importers should also check whether the Plastic Packaging Tax applies. From April 2025, HMRC charges £217.85 per tonne on plastic packaging manufactured in or imported into the UK that contains less than 30 per cent recycled plastic.
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 under the Employment Relations (Flexible Working) Act 2023, according to ACAS. A well-planned hybrid policy can improve retention, reduce commuting costs and lower your carbon footprint. Flexible working can also help women founders and employees balance business and caring responsibilities, supporting retention and widening your talent pool. If you are self-employed and work from home, read our Home Working Expenses Self Employed Can Claim Through HMRC guide.
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.
Remember that wage costs have also risen. The National Living Wage stands at £12.21 per hour for workers aged 21 and over from April 2025, according to HMRC. Our National Living Wage £12.21: what women founders pay guide explains what this means for employers.
Action steps to cut business costs and energy use
- Review your energy contract and compare at least three business tariffs before renewal.
- Check whether solar panels, battery storage or a green tariff fit your premises and budget.
- Claim available tax relief on energy-efficient equipment through the Annual Investment Allowance or full expensing.
- Fix leaks, fit water-saving devices and compare water retailers if you are in England or Scotland.
- Apply the waste hierarchy and check your liability for Plastic Packaging Tax.
- Document a flexible working policy and assess whether smaller premises could cut overheads.
- Schedule a quarterly spending review and benchmark costs against industry data.
Cutting costs does not mean cutting corners. By reviewing your energy, water, waste and workspace costs regularly, you can cut business costs and energy use in the UK and build a leaner, more resilient women-led business that is better prepared for future price rises.
