MPK Junction Petrol Station, Long Eaton, Derbyshire

December 2022

MPK Garages Group really are switched on when it comes to energy saving. Using bespoke energy data management analysis, they concluded that their open-fronted instore chillers, at their test site – Junction Petrol Station in Derbyshire, were accounting for 42% of the site’s energy overall.


The solution to reducing their energy usage was simple. They chose to retrofit durable, double paned, acrylic Swing1 fridge doors from DoubleCOOL. In double quick time, we installed 14 doors to approx. 8.75m of their open-fronted chillers. The installation took place over the course of a day, section by section, with minimal interruption to trading.


Since the installation, the MPK Group have continued to closely monitor energy usage, collecting and analysing the data. Results of the first month showed that an incredible 40% reduction in energy was achieved. In real terms, this represents a cost saving of £8k, and the installation will pay for itself well within a year, and will continue to keep paying back, year upon year. The success of the test site at Junction Petrol Station, has MPK all set to roll out fridge door installation to the wider group, of 26 further petrol station forecourts.


“Energy is one of the highest operating costs for our business and rising daily. It was (and is) imperative to look for energy reduction solutions to help energy efficiency, lower energy costs and improve environmental performance. In September 2022 we installed 14 DoubleCOOL Swing 1 doors (which is approx. 8.75m) to our refrigeration cabinets. The impact was immediate, we monitored our energy consumption and saw over 50% savings in the first month. We predict an annual energy cost saving of up to £8,000 meaning a payback on the doors in less than 12 months.” Comments Wayne Harrand Retail Director at MPK Garages.

Premier, Yoxall Staffordshire

October 2022

Yoxall Village Store and Post Office is operated under the Premier symbol, serving a rural Staffordshire community, of less than 2k residents, seven days a week from 7am until 9pm.


The general store owners aspire to a modern, open plan, visually pleasing store design, with a layout that’s accessible, appealing and comfortable for shoppers. When it came to enclosing 5 meters of open refrigeration cabinets, this local, independent retailer turned to DoubleCOOL for double quick supply and installation of 8, Swing 1 fridge doors.


Now their dairy produce, juices and pop, fresh meats and chilled produce including ready meals, sit neatly behind double paned acrylic hinged doors. Customers are benefitting from 100% transparency of neatly displayed chilled produce, accessed by lightweight smooth-opening and self-closing hinged doors, that are condensation free and have a finger safety gap. The Swing 1 doors are keeping the cold in, reducing the fridge’s power requirements, and preventing the store feeling cold for customers. Co-owner Mr Culbinder Singh is also set to benefit from a 60% reduction in energy usage, now that’s worth getting in touch with DoubleCOOL for!

NISA LOCAL, Blackpool, Lancashire

September 2022

Energy savings are starting to add up at Nisa Local (part of the Coop group) in Blackpool. Since DoubleCOOL retrofitted 32 Swing 1 acrylic fridge doors to their previously open-fronted fridges.

Like many convenience store operators, Blackpool’s Nisa Local franchisees were looking to make energy cost savings. With an 18.75m run of open chiller cabinets, constantly expelling costly chilled air into the shop, there was an instant energy saving to be had.

Nisa Local chose to display their “grab and go” meal deals, ready meals, dairy, meat, chilled alcoholic and soft drinks, behind closed doors. The installation took just 2 days, with minimal impact on the store operations, and the subsequent energy savings and benefits were instant.

With stainless steel, accessible handles, self-closing hinges with safety finger gaps, and great product visibility, there’s been no negative affect on sales of chilled ranges. With fridge energy cost savings alone in year one predicted at £7.5k, the retrofit fridge door return on investment will payback in well under two years.

Morrisions Daily, Llansantffraid, Wales

August 2022

This busy store, alongside a petrol station underwent a massive refurbishment as it moved to operate under the Morrisons Daily retail brand. Subsequently, EC Ashton & Son – the franchisee – have enclosed 7.5m of chilled drinks cabinets using DoubleCOOL Swing 1 Doors.

In April 2022, the store tripled its chilled range and underwent a massive refurbishment to improve customer experience, as it became a Morrisons Daily franchise.


The 7.5m stretch of chilled alcoholic drinks shelving was originally left open, however with running cost and customer comfort in mind, DoubleCOOL undertook the conversion to enclose the cabinets. With minimal interruption to trading – the store is open from 7.30am until 10pm daily – the retrofit of 12 Swing 1 fridge doors was completed in August 2022.


Now the white wine, rose and fizz sits alongside lagers and real ale IPAs cooling behind closed doors, with the chiller temperature maintained, energy usage reduced and increased customer comfort. The operators are so pleased with the results, that they’ve already placed an order for retrofitting DoubleCOOL fridge doors in a second store.
