Savings from Sustainability: 101

For many SMEs, sustainability feels like a “nice to have” – something to worry about when there’s more time or budget. But here’s the reality: sustainability saves money. Done right, it’s not a cost centre; it’s a profit driver.

The quickest way to build internal support for sustainability is to talk about the numbers. Savings can be measured, banked, and reinvested – and most require little upfront cost.

Where to find the quickest ROI

  1. Energy Efficiency
    Energy is almost always the first place to look. Typical UK SMEs can save 10–30% on energy bills through basic efficiency measures. If you haven’t looked at these quick wins, you should as soon as you can:

  • Switching to LEDs – Cheaper to run and last up to 10 times longer than halogen.

  • Optimising heating and cooling – Even 1°C adjustments to thermostat settings can reduce costs by 8%.

  • Stop draughts – draughty buildings can waste thousands annually. Use a 2p test, if you can fit a 2p coin in a gap (on the thin side), the gap is cost-effective to fix.

  • Fixing air leaks (in manufacturing) – Particularly in compressed air systems or draughty buildings, which can waste thousands annually.

  • Timers and sensors – Ensure lights, heating, and equipment aren’t running out of hours.

If you’re on a standard variable tariff, simply reviewing your energy contract or switching to a renewable business tariff can also make a noticeable difference.

  1. Waste Reduction
    Waste is often overlooked because it feels like a small cost – but the savings add up:

  • Segregation and recycling – Mixed waste disposal is the most expensive; separate materials wherever possible.

  • Right-sizing bins – Many SMEs pay for half-empty bins or too many collections.

  • Avoiding over-ordering – Better stock control means less waste and fewer disposal costs.

Typical savings are 5–15% of your waste management bill within months.

  1. Resource Use
    Think beyond energy and waste:

  • Reusing packaging – Many SMEs in retail and distribution save thousands by reusing boxes and pallets.

  • Going paperless – Cuts printing, paper, and storage costs.

  • Water savings – Simple things like fixing leaks or installing low-flow taps can reduce water bills significantly.

Quick actions to try this month

  1. Walk your site after hours – Are lights, computers, or machinery left running unnecessarily? Switch off and save.

  2. Check your bills – Look for unexplained spikes in energy or waste costs. They often point to easy fixes.

  3. Talk to your suppliers – Waste contractors, energy providers, and even packaging suppliers often have advice on cost-cutting opportunities.

  4. Engage your team – Staff often spot waste first – ask them for ideas.

Why it matters

Every £10,000 saved on energy or waste is £10,000 straight to your bottom line – and for SMEs, that can mean:

  • Contribution to hiring another staff member.

  • Buying new equipment.

  • Funding marketing or growth plans.

Better still, most of these changes pay for themselves quickly – often in under 12 months.
