Energy efficiency auditing is one of the fastest, lowest‑risk ways for UK businesses to reduce operating costs, shrink carbon footprints and build long‑term resilience. Boxfish delivers detailed, practical energy efficiency audits that show exactly where your sites are wasting energy, what to fix first, and the savings you can expect in both £ and kWh.
Energy Efficiency Auditing helps you understand how, where and why energy is used across your operations — so you can reduce consumption, cut utility costs, and lower carbon emissions.
Boxfish delivers practical, data‑led audits for SMEs and multi‑site organisations across the UK, identifying real‑world opportunities ranging from low/no‑cost improvements through to invest‑to‑save projects.
Key benefits of working with Boxfish:
Following our 4-step energy efficiency auditing process, clients can reduce their energy spend by up to 15% through implementing identified low/no costs measures and up to 25% from targeted, CAPEX upgrades.
We review your historic consumption data to understand how much is used and when, and to highlight patterns worth investigating further.
We assess how the site operates day‑to‑day, how equipment is controlled, and where losses/waste occur.
You receive a report showing recommended actions, plus the likely savings in carbon and cash — with priorities you can take forward quickly.
Follow on support to align the results with other carbon and sustainability obligations such as SECR and ESOS and where required, assistance to help implement the identified opportunities.
Boxfish has close to 30 years’ experience of energy efficiency auditing, helping UK SMEs identify and unlock:
Every site is different, but our auditors frequently identify opportunities such as:
Although the primary value often lies in energy savings, many organisations also benefit from targeted water efficiency assessments, especially where consumption is high, hot water demand is significant and where losses have gone unnoticed.
Water efficiency findings are provided as a supplementary section within your report, ensuring you capture additional savings without detracting from the core focus: energy reduction.
An energy efficiency consultant analyses how buildings and systems use energy, providing recommendations to reduce consumption, lower costs, and improve performance — often supporting sustainability and compliance goals.
Yes. Boxfish offers scalable audits for SMEs through to large organisations, focusing on practical, cost‑effective actions that fit your size and budget.
What are the key steps in an energy efficiency auditing?
We review consumption data, conduct a site audit to understand operations, then produce a report with recommended measures and estimated savings in both carbon and cost.
What recommendations can I expect?
Recommendations from our energy efficiency auditing support are varied but can include behavioural/management improvements, low‑cost optimisation and control changes, capital investment options, and renewable/clean energy integration opportunities.
Many organisations can start saving within weeks by implementing quick wins (controls, scheduling, operational changes). Larger projects typically follow an agreed business case and investment timetable.
Yes — energy efficiency auditing can be delivered as part of ESOS compliance activity or as standalone efficiency projects, depending on your drivers and requirements.
What information do you need from us?
Typically recent energy and water bills (or half‑hourly data if available), site lists/addresses, operating hours, and access to key plant rooms/controls during the visit.
Yes. We can support you from opportunity identification through to prioritisation, business case development, and implementation planning — ensuring measures are practical and deliverable.
