What to Expect During a DEC Assessment at Your Medical Practice

A Practical Guide to Securing Your Display Energy Certificate Without Disrupting Patient Care
For busy practice managers and doctors, finding the time to juggle patient care, administrative duties, and facility compliance can feel like an endless balancing act. When the time comes for your medical practice’s annual Display Energy Certificate (DEC) assessment, it is perfectly natural to anticipate a disruptive and time-consuming process. However, understanding exactly what the assessment entails can help you prepare efficiently and demystify the entire procedure.
 
With the right preparation and the right assessing partner, securing your DEC can be a straightforward, stress-free task that barely creates a ripple in your daily operations.

Understanding the Display Energy Certificate

A Display Energy Certificate is a legal requirement in the UK for buildings that are frequently visited by the public and exceed a specific floor area threshold. For medical practices, health centres, and surgeries, displaying a valid DEC in a prominent place is mandatory. 
The certificate provides an energy rating from A to G, which reflects the actual energy consumption of the building over the previous 12 months. Alongside the certificate, you will also receive an Advisory Report. This document details practical recommendations for improving your building's energy performance, helping you identify ways to reduce your carbon footprint and cut down on expensive overheads. While the regulation is strict, the process of obtaining the certificate does not have to be a burden on your practice.

Gathering Your Paperwork: The Crucial First Step

The key to a seamless DEC assessment lies in the preparation before the assessor even steps foot in your surgery. Because a DEC is based on actual energy usage, the most critical component of the assessment is your utility data.

Essential Utility Data

To ensure the process moves swiftly, you will need to gather 12 consecutive months of energy bills. This includes all gas and electricity statements covering the exact period being assessed. If your practice uses any other fuels, such as oil or biomass for heating, records for these must be provided as well. Having this data organised in advance prevents unnecessary administrative delays.

Supplementary Documentation

In addition to your energy bills, having a few other documents on hand will significantly speed up the process. If you possess them, provide the assessor with accurate floor plans of your medical practice. Furthermore, if your practice has had a DEC in the past, keep the previous certificate and its accompanying Advisory Report ready for review. Having these documents neatly compiled means the assessor spends less time digging for information and more time completing your certification.

The On-Site Visit: Non-Disruptive and Efficient

One of the primary concerns for doctors and practice managers is the potential disruption to patient care during the on-site visit. Rest assured, a professional DEC assessment is designed to be as unobtrusive as possible.

The Physical Survey

When the assessor arrives, they will need to conduct a physical survey of the premises. This involves a walk-through of the building to verify its size, layout, and the types of energy-consuming systems installed. They will visually inspect your heating, ventilation, and air conditioning (HVAC) systems, as well as your lighting and the general fabric of the building, such as windows and insulation. They may also need to take a few photographs of boiler plates or meter readings for their audit trail.

Maintaining Patient Confidentiality

The assessor will not need to interfere with medical equipment, interrupt consultations, or access sensitive patient areas unnecessarily. They simply need to observe the building's infrastructure. By communicating with your staff beforehand, you can ensure that the assessor is guided through the building swiftly, completely avoiding any disruption to the vital care your practitioners provide.
