Sainsbury's – National Project Management & Main Contractor

Energy & Technical Services were initially employed by Sainsbury’s in 2006 to implement one of the first phases of the Sainsbury’s 20 by 20 Sustainability Plan. We now hold Main Contractor status. We also act as the Clerk of Works and since 2011, we have seconded one of our Senior Consultant’s to work full time within the Sainsbury’s Energy and Engineering Department.

We have implemented a number of energy saving initiatives including refrigeration optimisation, HVAC repairs / refurbishments, BMS upgrades, voltage optimisation and LED lighting upgrades.

Our engineering skills are central to Sainsbury’s 20 by 20 Sustainability strategy and our core role is to evaluate new technologies and identify potential energy saving initiatives at store. We have acted as project manager for a number of roll-outs and we have also undertaken a number of successful energy trials which include ‘Low Footfall Lighting Control’, ‘Defrost On-demand’ and ‘EC Fan Installation’.


Early stakeholder engagement is essential to ensuring works are completed on time without impacting on trade. We work collaboratively with client representatives, Contractors, Suppliers and Store Managers to ensure project critical deadlines are met. Our Project Managers are equipped with tried and tested systems and tools which ensures we provide Sainsbury’s with intelligent programme management, informed decision-making and reduced risk.

Added Value / Achievements

Our collaborative approach with Sainsbury’s is an important aspect to the successful delivery of energy saving initiatives. Energy saving targets are agreed with the client prior to works commencing and form the baseline of our performance-based contract. Recent project examples include the Sainsbury’s LED programme (Graphite 6) which produced a cumulative energy saving of over 5 million kWh.

Woodie’s – Decarbonisation & Energy Performance Audit

In this case study, we provided a proven method to enable Woodie's to decarbonise its portfolio, and budgetary figures were obtained to allow the implementation of decarbonisation replacement/installations. Our proposed photovoltaic solution can enable the production of circa 70,000kWh of electricity annually. There is also a suggested destratification system, achieving savings of up to 20% in heating costs.

The Fulham Shore – ESOS Compliance & Consultation

The Energy Savings Opportunity Scheme is compulsory for large UK organisations. A total of 29,610,620kWh opportunities were identified for The Fulham Shore, resulting in 31,783,515 Kg of emissions being saved.

Woodie’s – Significant Cost Savings & Ongoing Support

Woodie’s is a 100% Irish owned chain of DIY outlets, and a subsidiary of the Grafton Group plc. Woodie’s are committed to minimising their environmental impact and with 35 stores in Ireland, sought external expertise to help establish control of energy usage and deliver deep, sustained energy and carbon savings.
