Free Evaluation Process

Start saving

The whole process is completely confidential, with each and every step giving a clearer image of exactly how powerPerfector can help you, whatever your carbon reduction and energy saving goals.

Nothing in this process is hidden – we use your data, show how we have calculated the savings and most importantly, by the last step, we are in a position to guarantee you the predicted Return on Investment (ROI).

In the extremely unlikely case that we do fall short, we have two possible solutions – rebate your savings to reach the ROI, or uninstall the unit free of charge and refund all monies spent. You can be comfortable knowing that with powerPerfector, you will never pay for a service without value.

Step 1. Send your data

We’ll need the past year’s data on:

  • Each incoming supply’s highest maximum demand.
  • The total kWh consumption on each incoming supply.
  • The current cost of supply or your price per kWh.
Step 2. We send you and estimate

We send you an estimate of the cost and benefits of powerPerfector to your site. If you like the numbers in the estimate, we’ll send you a voltage logger to measure your voltage profile. Once returned, we analyse this profile and send you an amended investment case with your recommended optimisation setting.

Step 3. Survey and proposal

We survey your site(s) and provide a more detailed proposal. This finalises all the precise details involved in the project, so we can confirm your capped costs and estimated savings. We then draft a comprehensive proposal for all the decision makers, clearly demonstrating the potential of a powerPerfector installation. If everyone is happy, we move to the penultimate step.

Step 4. Delivery and installation

At a time to suit you, our highly experienced engineering department arranges and coordinates the installation with one our Approved Contractors. Pre-works are completed prior to the final integration into your supply which normally takes from 2 to 4 hours.

Step 5. IPMVP evaluation

The final part of our energy-saving solution is an external evaluation of powerPerfector’s installed performance. This crucial work is carried out by EEVS Insight, the UK’s leading provider of energy efficiency performance measurement and verification services. This analysis will verify if we have met the guaranteed ROI.
