Case Study

Major energy refit for
high street retail store


Logo of Marks and Spencer


Marks & Spencer needed to carry out a major energy refit at one of its city stores, in order to modernise and implement a significant reduction in energy consumption.


Following an initial survey, we proposed a plan that was taken up by the client to deliver the following energy saving solutions: –

  • Intelligent Lighting controls
  • Energy efficient lighting redesign
  • BMS upgrades, including solar heating optimisation
  • Heat pumps for over door heaters
  • Lighting presence control
  • New, efficient hand dryers


The new technologies that we specified and installed achieved savings of over 28% and yielded an ROI within less than three years.

Clearworld is a valued partner. We would recommend them to other businesses that wish to reduce their energy consumption.
