National Delivery Service
Last updated: 3.06pm, Thursday 6th November 2025
Our client is one of the UK’s most established brands, with over 500 years of heritage, evolving from a postal service dedicated to the King and his Court into the modern international delivery network it is today. As part of ongoing infrastructure improvements, SOLIS Group was appointed to supply and install new, energy-efficient heating systems across three national delivery sorting offices and distribution centres located throughout Glasgow and Lanarkshire.
DELIVERY
SOLIS was responsible for the mechanical installation and upgrade of existing heating systems, replacing outdated equipment with modern, sustainable alternatives.
Works included:
-
Supply and installation of Remeha gas boilers known for their high efficiency, reliability, and low emissions.
-
Installation of new REZNOR gas-fired space heaters to provide consistent heating across large operational areas.
-
Redesign and resizing of gas pipework to meet new system requirements.
-
Full flushing and dosing of the boilers and associated radiators to ensure system longevity and optimal performance.
-
Application of thermal insulation to maximise energy retention and efficiency.
All installations were completed safely, within the project timeframe, and coordinated closely with on-site operations to minimise disruption to critical postal services.
IMPACT
The upgraded heating systems have provided the client with:
-
Improved energy efficiency and reduced operational costs
-
Lower carbon emissions, contributing to sustainability goals
-
Enhanced system reliability and improved working conditions for staff
The completion of the works across all three sites demonstrates SOLIS Group’s ability to deliver large-scale mechanical upgrades across live, operational environments without compromising performance or safety.
