Mantis offer strategic energy procurement solutions securing the most competitive energy contracts for your organisation.
Where we differ is that not only do we want the best energy rates for you, we also want you to use the least amount of energy possible and to reduce operating costs and emissions.
Through our energy monitoring, energy management and energy audit services we ensure no energy is wasted.
Energy Usage, Rate & Standing Charge Assessment
It all starts with a review and a comparison. Is your building energy usage, energy rates and standing charge higher or lower than the market average? And what is the best course of action?
We have a variety of clients who are on high energy tariffs and need to switch supplier and others on great low cost tariffs however with very large energy use. As you can imagine a different strategy is needed for each client and sometimes the solution is to look at changing supplier and reducing energy at the same time.
At Mantis we review the latest commercial rates, framework energy rates and standing charges based on electrical supply size. In addition to this we have data from over 2,500 buildings as well as benchmark energy use data to confirm if further energy savings are available.
Mantis offer a free no obligation desktop energy assessment for any public sector or commercial buildings that would like to understand there energy rates and energy usage better.

Energy Procurement
Our approach goes beyond simply securing a low tariff. We analyse your organisation’s energy usage profile, risk tolerance, and sustainability commitments to source the most suitable contract from the UK energy market.
As we work with large public sector organisations we can often negotiate large contracts with the big energy suppliers. Dealing with estate wide energy contracts can allow single building organisations to benefit from these preferential rates as we typically combine all upcoming deals into one large negotiation.
We have extensive experience in managing procurement for primary schools, secondary schools, colleges, universities, NHS hospitals, NHS health centres, housing associations, and large commercial building portfolios. All processes follow best-practice procurement protocols as well as following our own in house ISO 9001 approved quality management system.
If you’re nearing the end of your current supply contract or wanting to investigate alternative options for your energy procurement, our team at Mantis can support you.

Energy Monitoring & Advice
All too often with public sector and commercial buildings we use a lot more energy than we need to. Commercial buildings tend to use a lot of energy at weekends, in early mornings and at night when there is no one in the building and during holiday periods when buildings can be close for extended periods of time.
Our in house team can offer the following services:
Desktop & On Site Energy Audits: Get detailed insights into your energy consumption and prioritise quick wins actions with our energy audits. We offer both on-site audits and desktop energy audits to suit your needs and budget.
Smart Metering & Advanced Energy Monitoring: For sites with no smart metering we can ensure that energy suppliers fit a smart meter as standard and where this is challenging or you require more insight we can provide an advanced energy monitoring solution. Half hourly data can be very insightful however we can monitor energy down to each circuit if required. Wouldn’t it be great to know how much energy your lighting, plug sockets, kitchen equipment, refrigeration, IT suite, gyms, pool areas, heating, air conditioning, plant rooms consume and where the biggest opportunity is for energy reduction.
Peak Load Monitoring: Knowing your peak load when the building is using the maximum energy it can is more important than you may first think. While it doesn’t directly impact energy usage having access to a large supply and using very little can actually be costing you a lot in daily standing charges to keep a large supply to your building. In other scenarios you may need the extra supply for a decarbonisation project such as switching your gas boiler to an air source heat pump.
Building Energy Management Systems: Do you have an onsite building management system that can monitor energy usage? Are you struggling to get useful insights from this data or is the management system not working as you would like it to? We can provide a variety of services here such as: assessment of building energy management system (BMS or BEMS) data, condition reporting / audit of existing BMS & BEMS systems and upgrades to existing or outdated systems.

Energy Reduction Strategies
We monitor contract performance, validate bills, and highlight opportunities for savings or renewable integration throughout the term of your agreement. This ensures transparency, cost control, and alignment with your long-term goals.
