Whitbread, one of the UK’s most recognised hospitality brands, required a comprehensive Energy Performance Certificate (EPC) review across a large and diverse property portfolio. With 112 mixed-use hotel and restaurant locations nationwide, the project demanded speed, accuracy, and robust technical expertise.

Our compliance team was appointed to carry out full EPC surveys, modelling, and certification – all under a tight client deadline and with the expectation of the highest technical standards.

The Challenge

This project came with several challenges:

• Large-scale portfolio, spread across the UK
• Mixed-use buildings with varying age, construction types, and HVAC systems
• Strict deadlines driven by Whitbread’s internal compliance programme
• The need for high-accuracy modelling to inform future energy efficiency strategies

Whitbread required a partner that could deliver consistent results, maintain accuracy across all sites, and complete the full EPC review within the agreed timeframe.

Our Solution

To meet the scale and complexity of this project, we deployed our expert in-house energy compliance team, supported by advanced digital modelling tools.

1. Nationwide EPC Surveys

Our surveyors visited all 112 sites, capturing detailed data on:

• Building fabric
• HVAC systems
• Lighting and controls
• Energy usage patterns

This allowed us to develop an accurate profile for each location.

2. Advanced 3D Modelling Using Design Builder

We utilised the latest 3D modelling software, Design Builder, enabling us to:

• Visualise each property with precision
• Model energy performance in detail
• Identify inefficiencies in building fabric and systems
• Create compliant, high-accuracy non-domestic EPC outputs

This technology allowed us to maintain consistency across such a large and varied estate.

3. Tight Deadline Delivery

Despite the scale of the project, we successfully worked within a strict and immovable deadline.
Our streamlined internal processes, experienced team, and clear communication with Whitbread ensured the project remained on schedule.

Results

• 112 full EPC surveys completed nationwide
•  High-accuracy modelling delivered using 3D Design Builder
• All EPCs submitted within the client’s tight deadline
• Consistent quality across a diverse property portfolio
• Actionable energy insights provided to help inform future building upgrades

Whitbread now has a complete and up-to-date EPC dataset across their UK estate, supporting compliance, sustainability goals, and operational planning

Conclusion

This project demonstrates our ability to deliver large-scale, high-pressure EPC programmes for major UK brands. With advanced modelling tools, skilled in-house professionals, and efficient project management, we supported Whitbread in achieving full EPC compliance across a complex and geographically dispersed portfolio.
