Marston’s Inns & Taverns


Marston’s is the leading independent brewing and pub retailing business in the UK. With around 500 managed pubs and 1650 tenanted/franchised pubs, the estate consumes a significant amount of energy.


The Problem

The business has a growing focus on energy efficiency in order to meet carbon emissions targets and drive down the operational costs associated with electricity and energy prices. To meet these challenges Marston’s has taken a proactive approach: “Improving the environmental performance of our pubs is very much about engineering the right solutions for our premises. Our new-build and refurbishment programmes put us in an excellent position to design in these improvements from the outset.” Andy Kershaw, Group Facilities.

Our Solution

Marston’s first trialled two powerPerfector units in 2010. After exceeding the predicted savings VPO® has been rapidly installed at 40 of the highest energy consuming pubs across the managed estate.

Importantly the programme was delivered without affecting the day-to-day operation of the business. The adoption of new technologies on a large scale can often be problematic as there are usually learning curves or teething problems associated with it. As the size and scope of a project increases so do potential overruns in time or cost. These problems can cause projects and programmes to lose direction, lose value or even cause them to be cancelled altogether.

The importance of procuring a solution that properly manages implementation cannot be overstated. By choosing to adopt VPO®, Marston’s was assured of engineering excellence.

The Results

Our total solution was able to install 40 retrofits and a further 60 new build pubs, meeting client timelines and expectations with an engineering solution that matched the robustness and reliability of the technology. It is because of delivery that Marston’s have signed a framework agreement with powerPerfector lasting three years and securing a further 90 sites.

The programme is saving 353 tonnes of CO2 annually.

The Overview

  • 648,784 kWh Saved
  • 352,940 CO2kg Saved
  • £52,257 Saved

“Throughout the initial trial period and the subsequent roll-out programme powerPerfector continued to over deliver, and the expert project management ensured effective communication at all times with minimum disruption to sites, giving us a full turn-key project solution along with some fantastic energy savings.”

Mark Stafford, Project Manager

“Marston’s Inns & Taverns opted for powerPerfector above other technologies after a successful trial of two sites in 2010 which saw savings in excess of 9%.”
