Where an EPC rates how efficient a building's design should be, a DEC rates how it really performs in use. It's a legal requirement for buildings over 250 m² that are occupied by a public authority and frequently visited by the public.
Companies operating in any type of commercial property may opt to have a voluntary DEC survey carried out with a view to using it as a tool for managing their energy efficiency.
Property owners in Scotland with any commercial building 1000m2 or larger are legally required to have a Section 63 survey and action plan in addition to their EPC when selling or renting. Increasingly, they are opting to have an annual DEC carried out in place of making the improvements on their action plans. Read more about Section 63 surveys and action plans here.
A DEC survey is also an approved method of assessing buildings for the Government’s Energy Savings Opportunities Scheme (ESOS).
Simply request your quote using our contact form or by phone. Our customer care team will quickly get in touch during opening hours.
We will arrange an appointment with you, carry out the survey, and once completed send you an invoice.
As soon as we receive payment of the invoice, we will email your DEC. We also offer corporate accounts, with survey delivery on completion and monthly billing.
Typical examples are council offices, state schools, libraries, hospitals and other public-sector buildings open to visitors. The rules apply in England and Wales. A building only partly used by a public authority still counts, and a site with several buildings needs a DEC for each one that meets the test.
If you're responsible for the building, you need two things: a valid DEC on display and a valid advisory report. A local authority can issue a £500 penalty for not displaying a DEC and £1,000 for not having an advisory report.
Buildings that don't have to have one, such as private offices, can still commission a DEC to track their energy use year on year.
After the site visit, it takes up to 5 working days to produce your DEC. Once complete you will receive 2 documents, the DEC itself and a DEC Advisory Report which gives advice on how to improve the rating of your property.
The advisory report groups its recommendations by payback: measures that pay for themselves within 3 years, in 3 to 7 years, and over 7 years.
For example, a secondary school may have a main building, a sports hall, a language block and a music hall. If any of these buildings are over 250m² they will each require a DEC. It is important to provide the GIA, energy bills and floor plans for each building needing a survey.
During the survey, the assessor will need to have access to any boiler/plant rooms. It’s useful to have a facilities or business manager available during the survey as a short survey about occupancy and the heating controls will need to be carried out on site.
Following the site survey, the data will be collated at the desk and the DEC and recommendation report will be produced in government approved software.
If your building is over 1,000 m², the DEC is valid for 12 months and the Advisory Report for 7 years.
If your building is between 250 m² and 1,000 m², the DEC and the Advisory Report are both valid for 10 years.
Scottish property owners who opt for a DEC as a result of their Section 63 survey will be required to provide an annual DEC until they make the improvements on the Section 63 action plan.
Search the government's Find an energy certificate service by postcode or certificate number. Every DEC is lodged there by the accredited assessor who produced it, so you can check when yours expires.
The basic information we need to be able to provide you with a price for the survey is:
Once we have provided you with a quote, if you wish to go ahead and book we will also need invoicing details and contact details for whoever will be providing further data. We don't charge up-front, but will invoice you for the work on completion, and release the DEC to you upon receipt of payment.
After you have booked with us we will contact you or, if you prefer, an alternative point of contact to discuss the survey process and arrange an appointment.

Our Display Energy Certificates start from £99.95+VAT, depending on the size and location of the building. Our prices are competitive and every building is quoted on its own merits. Send us the details and we'll come back with a firm figure, and the advice that goes with it.
A DEC shows how much energy a public building actually uses, based on its meter readings over the last 12 months, and rates it from A (lowest carbon emissions) to G (highest). It must be displayed in a prominent place where visitors can see it, and it comes with an advisory report on how to cut energy use.
You need one if your building has a total useful floor area over 250 m², is occupied in whole or in part by a public authority, and is frequently visited by the public. Typical examples are council offices, state schools, libraries and hospitals in England and Wales. Other buildings can have one voluntarily.
For a building over 1,000 m², the DEC is valid for 12 months and the advisory report for 7 years. For a building between 250 m² and 1,000 m², the DEC and the advisory report are both valid for 10 years.
In a prominent place clearly visible to the public at all times, usually the main entrance or reception. Government guidance says it should be no smaller than A3.
A local authority can issue a £500 penalty for failing to display a valid DEC, and £1,000 for not having a valid advisory report.
Search the government's Find an energy certificate service on GOV.UK by postcode or certificate number. Every DEC is lodged there by the accredited assessor who produced it.
The report that comes with a DEC. It lists ways to cut the building's energy use, grouped by how quickly they pay for themselves: within 3 years, in 3 to 7 years, and over 7 years.
DEC on-site surveys take about 30 minutes for small properties, up to an entire day for a large property such as a big hotel or care home. If a renewal is done before expiry and you confirm nothing in the building has changed, it can be completed without another site visit.
Send us the gross internal area (GIA) of the property, 12 months of consecutive energy bills with meter readings, and a floor plan before the appointment. Make sure the assessor can reach all areas, including boiler and plant rooms, and gather any information you have on the heating, hot water, ventilation and lighting.
