Building Energy Audits · Energy Management · Compliance Support
Energy Efficiency.
Engineered by Science.
Practical building energy audits, ongoing energy management and specialist energy, carbon and compliance support for organisations with buildings.
Oxford Energy Services is an independent building energy consultancy helping building managers, facilities teams and operations managers understand where energy is being wasted, meet relevant energy obligations and decide what to do next.
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
Research-level science. Practical building experience.
Oxford Energy Services is technically led by Dr Russell Layberry, Director and Technical Lead. His background spans research-level physics, University of Oxford building-energy research, energy monitoring and software development, practical building-services expertise and more than 300 commercial building energy audits.

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.
Russell’s combination of scientific research, software development and practical building experience means he can understand the physics, interrogate the data, inspect the systems and decide which actions are genuinely worth pursuing.
Services
Start with an audit, ongoing support or a compliance requirement
OES provides practical building energy audits, ongoing energy-management support and specialist help with ESOS, ISO 50001, energy reporting, carbon planning and technical energy decisions.
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.
View Building Energy AuditsEnergy Management Support (Retainer)
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
Energy, Carbon & Compliance Support
ESOS, ISO 50001, reporting and technical energy decisions.
Focused support for organisations that need help with compliance, management systems, reporting or complex energy and carbon decisions.
- ESOS Phase 4 scoping and audits
- Lead Assessor review and sign-off
- ISO 50001 preparation and improvement
- SECR and annual energy reporting
- Carbon and decarbonisation planning
- Independent technical reviews
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.
What smart-meter data can reveal
Half-hourly data can expose patterns, baseloads and unusual demand, but practical interpretation is still essential.
Read the smart-meter articleOvernight energy use in commercial buildings
Night-load, weekends and low-occupancy periods can reveal hidden energy use and poor control.

Carbon reporting is useful, but it does not automatically identify or deliver practical energy savings.

Scientific expertise grounded in real buildings
Russell combines advanced scientific training with practical technical experience across buildings, controls, monitoring, energy data and building services. This breadth helps OES move beyond generic recommendations and identify what is really happening in a building.

Practical, technical and trusted
“Working with Russell is a joy — he is constantly brimming with new ideas and gets his hands dirty building functional prototypes from scratch.”
“I would recommend him for research and consultancy work in relation to energy and buildings.”
“Russ supported us with an energy management audit that was practical, clear and extremely useful. His support helped us understand our energy position and identify sensible actions.”
