Building Energy Audits & Energy Management Support
Energy Efficiency.
Engineered by Science.
Practical building energy audits for lower bills, less waste and better control of your building.
Oxford Energy Services is an independent building energy consultancy helping building managers, facilities teams and operations managers understand where energy is being wasted — and what to do about it.
If you manage a building and have been asked to reduce energy costs, improve energy performance or report progress to senior management, OES can help you get a clear, practical plan.
Professional credentials
Led by a Certified Energy Manager and AEE Individual Member
OES is led by Dr Russell Layberry, combining physics, energy management, building audits, technical consultancy and practical building-services understanding.

No jargon. No generic net zero waffle.
Clear energy diagnosis for real buildings
The focus is simple: less energy waste, lower bills and better control of your building.
OES audits are designed for organisations that need useful recommendations, not a long report that sits on a shelf.
For organisations comparing energy audit companies or consultancies, the important question is not simply who can produce a report. It is who can investigate how the building is actually operating, interpret the energy data and turn the findings into practical priorities.
Services
Start with an audit. Continue with practical support.
OES provides focused building energy audits and ongoing energy management support, backed by practical investigation, energy data analysis and experienced technical judgement.
Building Energy Audit
One building. Practical diagnosis. Clear next steps.
A building energy audit is the best starting point if you are unsure where energy is being used or wasted.
- Electricity and gas use
- Half-hourly electricity data, where available
- Night load and out-of-hours consumption
- Heating, lighting and controls
- Plant and operational issues
- Quick wins and capital measures worth investigating
You receive a concise summary of what is happening in the building, where the main opportunities are and what should be done next.

Practical support without employing a full-time energy manager.
Many organisations do not need a full-time energy manager, but they do need someone experienced who can look at the data, sense-check proposals and help keep energy actions moving.
- Energy data review
- Night-load checks
- Quote and proposal review
- Advice on heating, lighting, controls and solar PV
- Energy action plans
- Board-level energy updates
Audits & Energy Insights
Energy advice grounded in data, site inspection and technical understanding
OES work is designed for people who need to manage real buildings, budgets and operational problems.
Useful insight comes from connecting what the energy data shows with how plant, controls, occupancy and operating patterns behave in practice.
Practical energy insights
Look beyond the obvious assumptions
Building energy waste often becomes clearer when data, operating hours and real building behaviour are considered together.
Does a smart meter tell you everything?
Energy data can reveal important patterns, but it still needs context and practical interpretation.
Read the smart meter myth busterWhat happens when the building should be quiet?
Night-load, weekends and low-occupancy periods can expose avoidable energy use.
Read the out-of-hours myth busterEnergy waste is not always obvious
Waste can sit in schedules, controls, plant operation and patterns that have gradually become normal.
