Frequently Asked Questions

A TM44 inspection is a mandatory audit of air conditioning systems with a combined output of 12kW or more, required under the Energy Performance of Buildings Directive (EPBD). It was brought into UK law in 2011 and must be carried out every five years by an accredited Air Conditioning Energy Assessor. Learn more about our TM44 service →

Any business or building operator in the UK with air conditioning systems with a combined effective rated output greater than 12kW is legally required to have a TM44 inspection every five years. This applies to offices, retail premises, healthcare facilities, data centres and any other commercial building with qualifying systems.

Failure to comply with TM44 regulations can result in a fine. It is the legal responsibility of the operator of the air conditioning systems to ensure they have a valid certificate. If you have just moved into a space with air conditioning, you must have a valid report within three months of occupation.

Every five years. Systems over 12kW should have been inspected by 4th January 2011. New systems over 12kW installed after January 2008 must be inspected within 5 years of being put into service. From April 2012, all TM44 reports must be lodged onto the Landmark database.

The duration depends on the size and complexity of your systems. Most commercial inspections are completed within a day. All reports and certificates are provided within ten days of the inspection, and lodged on the Landmark database as required by law.

The report identifies whether your air conditioning systems are energy efficiently maintained and managed. It includes an inventory of installed components, actual usage and general condition, identification of potential improvements, measurements of air quality and air flow, and recommendations for energy savings. Our inspectors often go above and beyond by providing additional energy efficiency advice during each site visit.

Yes. If you have just moved into a space or acquired a building with air conditioning, the regulation requires that you must have a valid air conditioning report within three months of occupation. Be aware of partial re-fit works — if any part of an old A/C system is left in place, the site will require a current air conditioning report.

Commercial solar PV systems convert sunlight into electricity using photovoltaic panels installed on your building's roof or land. The electricity generated can be used directly by your business, stored in batteries for later use, or exported to the grid. This reduces your dependence on grid energy and lowers your electricity bills.

ROI varies depending on system size, energy consumption, roof orientation and current energy tariffs. Most commercial solar installations achieve payback within 5–8 years, with systems typically lasting 25+ years. Battery storage can further improve ROI by maximising self-consumption and protecting against energy price volatility. Register your interest for a tailored assessment →

Battery storage systems store excess solar energy generated during the day for use at night or during peak tariff periods. While not essential, battery storage significantly increases the proportion of your own solar energy you consume (self-consumption rate), reducing grid dependency and protecting against energy price volatility.

Most commercial buildings with a south, east or west-facing roof are suitable. We assess roof structure, orientation, shading, available space and your energy consumption profile to design the optimal system. Ground-mounted systems are also available where roof space is limited. Contact us for a free initial assessment.

We provide end-to-end support: initial consultation and feasibility assessment, system design and specification, installation management, grid connection, commissioning, and ongoing maintenance. We also provide web-based real-time energy monitoring so you can track generation and consumption at all times.

Decarbonisation is the process of removing or reducing all man-made carbon emissions with the goal to eliminate them altogether — reaching net-zero emissions. It is achieved by implementing low-carbon technologies such as renewable energy, energy monitoring, efficiency improvements and strategic planning. Read our full decarbonisation guide →

Energy price volatility is set to become normality for decades to come. The UK has set a target to slash emissions by 78% by 2035. Businesses that act now will reduce operating costs, future-proof against regulation, and gain competitive advantage. Making no decision will set the business back massively in the near term.

Our eight-point action plan covers: (1) Benchmark current energy use, (2) Assess available technology, (3) Confirm leadership commitment, (4) Measure and manage base load, (5) Match the right renewable solution, (6) Full feasibility study, (7) Review the plan, (8) Implement. We guide you through every stage. See the full plan →

We get involved from the moment you call us. Our job is to lead you through all eight stages, acting as your expert adviser, project manager, and technical solution procurer. We ensure best fit, maximum results with minimal risk. With over 600 client projects delivered, our reputation is based on your success.

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment scheme for large UK organisations (250+ employees or £44m+ turnover and £38m+ balance sheet). Qualifying organisations must carry out ESOS assessments every four years. We guide you through the full process from qualification to compliance.

Streamlined Energy and Carbon Reporting (SECR) requires qualifying large UK companies to report on their energy use, carbon emissions and energy efficiency actions in their annual reports. We help qualifying organisations meet their SECR obligations accurately and efficiently.

An Energy Performance Certificate (EPC) rates a building's energy efficiency based on its physical characteristics and is required for sale, let or construction. A Display Energy Certificate (DEC) shows actual energy consumption and is required for public buildings over 250m². We provide both for commercial and non-domestic buildings.

ISO 50001 is the international Energy Management Standard. It provides a framework for organisations to improve energy performance, efficiency and consumption. Our ISO programmes focus on delivering tangible, measurable results — not just collecting badges. We have supported and delivered ISO 50001 certification to clients across multiple sectors.

We provide services across the UK. Geography is not a limiting factor — we have delivered projects for clients from national facilities management providers to global businesses as far reaching as Japan and the US. Based in Trowbridge, Wiltshire, we operate nationwide.
