Black & White Facilities / Service brief
Display Energy Certificates
Coordinate a DEC assessment around the building’s occupation, use and energy records. For public-building requirements, renewals or missing documentation, first establish the assessment boundary; operational consumption underpins a DEC, while an EPC assesses building energy performance on a different basis.

Overview
State the certificate requirement and the outcome needed by the responsible occupier. Identify the premises, affected users and any change of use so the assessment brief reflects the current building arrangement rather than simply repeating earlier documentation.
Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.

What the service can include
The instruction defines the premises, floor area, energy evidence and assessment needs. It brings together the relevant accredited assessor with the certificate and advisory-report work. Resolve gaps or unusual records through that process instead of substituting estimates without support.
What to consider
Check the premises against the applicable requirements before assuming a DEC is needed or determining validity. A DEC is not required for every commercial property. Gathering bills and providing energy advice are different activities from accredited assessment and lodgement.
Our proposal records the assessment work included in the instruction and what remains for the occupier or property team. Any associated repairs or specialist tasks are scoped separately, with responsibility for arrangements and records made explicit.
Before we visit
Supply area information, occupancy and use details, and consumption records covering the relevant period. Flag generation on site and any shared supplies. Identify the occupier responsible and the contact who will coordinate evidence for the assessor.
How we help
We confirm the assessment need and organise its supporting records. The assessor helps resolve missing information and boundary questions. Handover includes the certificate and advisory material, plus arrangements for display and later review wherever these are required.
An estate certificate programme uses agreed reporting and escalation arrangements while retaining contacts and requirements at each location. Keep actions attached to the relevant building or service area, with an identified route for decisions affecting the wider operation.
What affects cost and timing
The assessor’s requirements, building complexity, shared supplies and availability of records influence the price. Recovering missing information may need a separate instruction. Allow time to settle data queries ahead of the date by which the certificate is needed.
Provide operating times, critical periods and details of activities that must continue. Reflect these in the programme and price, including any phased visits, additional access arrangements and reporting needed for day-to-day site management.
Sector applications
Where site work is required, the operating brief needs to reflect occupancy. Consider staff and visitors in Offices, trading and deliveries in Retail, guest areas and food operations in Hospitality, and teaching in education. Our complete service and project offering supports all sectors; working arrangements follow the actual activities at the premises.
Local coverage
Our area for DEC enquiries spans Northumberland, Tyne and Wear, County Durham and Tees Valley, with coverage in Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough. View all locations provides the location details for planning an estate instruction.
An estate DEC enquiry should identify the contact and working restrictions for each address. Use the common brief to retain the differences between premises as well as the shared requirements.
Frequently asked questions
Is a DEC the same as an EPC?
No. The two certificates use different assessment approaches and fulfil different purposes.
Does every business property need a DEC?
No. Apply the relevant current criteria to the premises’ actual occupation and use.
Can utility bills alone produce a certificate?
Bills are only part of the evidence; the assessor also needs building details and clarity about gaps or assessment boundaries.
Can certificates be coordinated across an estate?
Yes. Coordinate the programme while keeping each building’s assessment boundary and supporting records distinct.
Knowledge and guidance
Before preparing the instruction, see planning an energy improvement project and building management systems explained for related background. Use Official guidance for the relevant DEC context. Other reading is available in the Knowledge Centre.
