Describe the outcome required as well as the immediate issue. The starting information should identify the location, people affected and any change in use, so the assessment addresses the current requirement rather than simply repeating the previous arrangement.
What the service can include
The brief identifies the building, energy records, floor-area information and assessment requirements. It coordinates the appropriately accredited assessor and the certificate and advisory-report process. Missing or unusual data needs resolving rather than replacing it with an unsupported estimate.
Decisions that shape the service
Not every commercial building needs a DEC. Applicability and validity depend on the current requirements and the actual premises. The accredited assessment and lodgement process is distinct from general energy-management advice or gathering utility bills.
The proposal identifies the responsibilities that remain with the site or property team and the work included in our instruction. Connected repairs and specialist activities receive their own clear scope, so each person understands what they must arrange and what records they will receive.
Assessment and preparation
Provide the property details, occupier responsibilities and existing certificates. Identify shared meters and records held by tenants or managers. Agree access and the authority to commission the assessment.
How the service proceeds
We establish the requirement and organise the necessary information for assessment. Data gaps and boundaries are clarified with the assessor. Handover retains the certificate, advisory information and the arrangements for display and future review where required.
The property owner receives a clear account of the work and any follow-up required. Where premises are occupied, we agree the relevant notices, access and handback arrangements so users understand what has changed and who to contact afterwards.
Cost, timing and disruption
Building complexity, data availability, shared supplies and assessor requirements affect cost. Gathering missing records may be separate work. Start early enough to resolve data questions before the required certificate date.
Agree access, occupant communication and any associated reinstatement before work starts. For a remotely managed property, identify the local contact and approval route so findings can receive a decision without losing the detail needed by the owner.
Property and sector applications
Managing agents need responsibilities and approvals connected to the correct owner. Residential blocks need communal and individual areas distinguished. Retail and hospitality need work coordinated with customers and occupiers. Our complete service and project offering supports all sectors, with scope suited to the property and the people using it.
Local coverage
We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough. View all locations.
For several properties, provide separate access and occupancy information. A remote owner can nominate a local representative while retaining a clear route for approving the work.
Frequently asked questions
Is a DEC the same as an EPC?
No. They have different assessment bases and purposes.
Does every business property need a DEC?
No. Check the current criteria against the building's use and occupancy.
Can utility bills alone produce a certificate?
The assessor needs the relevant building and energy information, including any data or boundary questions.
Who supplies data in a shared building?
Agree responsibility with the occupier and parties holding the relevant meter and area records.
