Marshall Cotterill
IT Manager, Greenhous
Overview
With impressive credentials, Greenhous Group Holdings can boast sales of over 100,000 vehicles every year, an annual turnover exceeding £700 million and an army of over 800 staff – across two clearly defined business areas:
- Greenhous car and commercial vehicle dealership, which comprises of 16 franchised sites in the West Midlands area, including Vauxhall, VW Commercials, Nissan, Ford, Volvo and DAF Trucks, as well as an extensive bodyshop network.
- Smart Fleet Solutions operate in several different business areas throughout the UK, from vehicle retailing and technical services through to refurbishment and inspection.
The Problem
Through continued success and expansion Greenhous made the decision to relocate their headquarters to accommodate their growing team. They needed a new communications solution installing in their new office, and across their multiple sites. With additional users and an annual call volume in the region of 1 million calls per year, they required more reliable support for their telephony provision while reducing their annual spend.
Greenhous record their calls for training and monitoring purposes, so with the advent of GDPR, it was imperative that call recording and storing was compliant with GDPR legislation. They needed a company with reliable SLAs and who were fast to deliver the solution in the event of a fault or issue occurring.
About the Client
Greenhous Group Holdings is listed in the Sunday Times Top 100 largest private companies in the UK. They have roots dating back over 100 years and are renowned for being one of the country’s largest and most diverse automotive groups.

How we made it all come together
The Solution
Pre-planning was conducted through joined-up meetings with the Greenhous team to identify, discover and plan the best solution to implement changes – confirming what would be achieved on site.
Seriun installed a new enterprise-grade phone system, with new IP handsets and free call packages. This meant moving Greenhous from ISDN to SIP and as a result they are now enjoying significant annual savings of £20k.
The Benefits
Greenhous now benefits from a modern, efficient and economical communications system that has reduced costs by £20k per year. The new system ensures GDPR-compliant call recording and reporting, improved reliability, and better support for their telephony provision across multiple sites.
