Carlton Services.

Carlton Services is a specialist engineering business delivering air conditioning, refrigeration and catering solutions, built on high-quality installs and long-term maintenance contracts.  

Since partnering with GEL (formerly Infinity Nation) in 2020, the focus has been on supporting sustainable growth – not just increasing lead volume, but driving higher-value work and improving overall profitability. 

Following a period of plateaued revenue, Carlton needed a more commercially aligned approach to digital – one that connected marketing performance directly to business outcomes. 

As a result, our work evolved into a true partnership model: supporting Carlton’s expansion as they scale their engineering team, increase service capacity, and grow demand for recurring, service-led revenue. 

Our process.

Rather than focusing purely on channel performance, we built a strategy centred around profitability, customer value and long-term growth, working closely with Carlton to align marketing with their monthly P&L. 

Our approach included: 

Value-led Paid Media strategy: Shifted away from volume-led lead generation to prioritise higher-intent enquiries and higher job value, aligning ads, messaging and landing experience to attract more profitable work.  

Full-funnel demand capture: Built campaigns across core growth areas (Air Conditioning, Refrigeration, Catering), combining high-intent searches with education-led content to convert in a competitive market.  

Website & UX optimisation: Continual refinement of landing pages and user journeys to maximise conversion rate and profitability from Carlton’s drop-ship and service model – ensuring every visit delivers commercial value. 

Lifetime value & retention focus: Supported revenue growth through maintenance upsells, re-engagement campaigns and strengthening trust signals (reviews, case studies and aftercare messaging) to drive repeat, higher-margin work. 

Commercial partnership model: Worked beyond channel metrics like ROAS, using monthly performance discussions to understand how marketing contributes to overall business growth and operational scaling. 

As Carlton continues to expand, our focus remains on supporting their long-term growth – ensuring their digital ecosystem continues to drive profitable demand, operational efficiency and sustained success for this family-run business.
