SLMC-Consulting More Than Experience


Our Founder Sarah-Louise McCartney MCIM

I am a marketing professional working in the construction and building products industry with senior management experience and board level exposure across all aspects of strategic and operational management. I have significant cross functional experience in Marketing, Sales and Customer service.

With circa 20 years experience working in managerial positions, I have accrued skills imperative to the successful running of a business.  

I am confident in my abilities primarily due to my tenacious attitude which is unfaltering when under pressure. Finding solutions to problems and reaching the end of the task or project is incredibly satisfying whether this is due to a team or individual initiative.

Key Successes

November 2013  –  December 2015

Project management of the rebrand from 45 individual Roofing, Roofline, Window, Sheet and Drainage brands across the 180+ locations of the business to four main SIG brands.   Working with internal resources and external companies along with a predetermined budget of circa £1.7m to create and agree a program to ensure all businesses transitioned through two phases.  Initial dual branding phase and final end game phase.  This included the coordination of brand guidelines to ensure that each part of the business was branded with a consistent approach.   

FIT Show 2017 with SIG Building Plastics

May 2017  –  May 2017

Successful project management to exhibit SIG Building Plastics  at the FIT Show 2017.  The main aim was to raise awareness in the Glazing industry for the business and brand, putting the business firmly back in the market following the previous project of the company rebrand.  Working the exhibition project across all elements including booking the space, working with the design agency to create stand design, build, exhibition program, stand staffing plan and key messages.  Industry press meetings and an interview on FIT Show TV which can be seen at the below link helped further support our aim.
