Assessment through the appropriate accredited professional

EPC and DEC Certificate Coordination in London

Arrange the right energy assessment for a home, business property or public building through an appropriately accredited assessor. HCS provides the enquiry and coordination route; the appointed assessor undertakes the assessment and certificate work. For decisions about upgrades, a letting or an unsatisfactory rating, use our separate MEES and EPC advisory service.

Service Overview

A defined appointment for your property and purpose

Start with the certificate you need and the transaction or reporting purpose. An Energy Performance Certificate and a Display Energy Certificate answer different questions, so the assessment cannot be selected simply from the building's postcode. A domestic or non-domestic EPC assessment is distinct from a DEC based on a public building's operational energy use. HCS coordinates the information and appointment, while the responsible accredited assessor is identified before the instruction is accepted.

Service Scope

Choose the certificate and prepare the evidence

Domestic EPC appointments

Provide the home's address, type and available evidence of its construction and improvements. The assessor determines the appropriate assessment route and evidence needed. A listing description or an owner's recollection should not be substituted for information the assessor needs to verify.

Non-domestic EPC appointments

Define the premises, assessed area and use, including any mixed-use or separately occupied parts. Available plans, services details and access arrangements help the assessor scope the work and identify any information needed before the assessment can be completed.

Display Energy Certificates

Prepare the building area, operating information and energy records required for a DEC. The assessment and advisory report use a different evidence base from an EPC, so utility data and its coverage period need particular attention.

Evidence and access coordination

Bring together existing certificates, drawings, specifications and records of completed improvements. Agree access to relevant areas with occupants and facilities staff. The assessor decides how supplied evidence can be used and records any limitations in the assessment process.

Certificate handover and next decisions

The appointed assessor provides the certificate and associated reporting within their scope. HCS can help connect the resulting information to a separate building-improvement brief, but the existence of a certificate alone does not decide legal compliance or the suitability of works.

Preparing The Brief

Information and deliverables to agree

What to send

  • Property address, premises type and the reason the certificate is needed.
  • An existing certificate or register reference, if one is available.
  • Plans, floor-area information and accessible evidence of construction and improvements.
  • Relevant building-services information and, for a DEC, the requested energy records.
  • Occupancy arrangements, access contacts and the transaction or reporting deadline.

The commissioned outputs

  • The agreed EPC or DEC produced by the appointed accredited assessor.
  • The associated recommendation or advisory report applicable to that assessment.
  • Certificate and register information supplied by the assessor following completion.
  • A record of the premises and assessment type covered by the appointment.
  • Identification of any separate building-advisory follow-up requested by the client.
From Enquiry To Report

How the instruction is developed

01

Identify the assessment

Send the property details, intended use of the certificate and any existing reference number. Establish whether an existing certificate is sufficient or whether a new assessment needs to be scoped with the relevant accredited assessor.

02

Confirm the assessor and evidence

The proposal identifies the assessor, assessment type, information requirements and agreed fee and timing. HCS coordinates the records and access needed; accreditation for the particular work is checked before appointment.

03

Complete the assessment

The appointed assessor visits or obtains the information required by the applicable assessment process. Questions about construction, systems or energy data are resolved with the client and building operator as necessary.

04

Receive and review the output

The assessor completes the certificate and applicable lodgement and reporting. Check that the property details and scope match the instruction, then identify any separate advisory, legal or improvement decisions arising from the result.

Responsibilities And Limits

Agree the professional roles and scope

HCS coordinates this service; EPC and DEC assessment and certification are undertaken by the appointed accredited assessor.

No particular rating, transaction acceptance or improvement outcome is guaranteed before assessment.

An EPC or DEC does not replace a condition survey, detailed retrofit design or legal advice on a particular property obligation.

Improvement works and any subsequent reassessment require their own agreed scope.

London Technical Context & Governance

London Technical Delivery & Governance for EPC & DEC Certificates

Delivering accurate, defensible epc and dec certificate coordination in london across Greater London requires close attention to local building typology, substrate behaviour, tenure structure and borough regulatory context. Across North West and Central London—including Camden, Westminster, Kensington and Chelsea, Islington, Barnet, Brent, Haringey, Hackney, Wandsworth and Richmond—Victorian and Edwardian solid-brick terraces, Georgian stucco townhouses, inter-war mansion blocks and modern reinforced-concrete frames present markedly different technical risk profiles. Start with the certificate you need and the transaction or reporting purpose. An Energy Performance Certificate and a Display Energy Certificate answer different questions, so the assessment cannot be selected simply from the building's postcode. A domestic or non-domestic EPC assessment is distinct from a DEC based on a public building's operational energy use. HCS coordinates the information and appointment, while the responsible accredited assessor is identified before the instruction is accepted. By anchoring each instruction to verified site observations and primary documentation (Purpose: Provide the home's address, type and available evidence of its construction and improvements. The assessor determines the appropriate assessment route and evidence needed. A listing description or an owner's recollection should not be substituted for information the assessor needs to verify.; Delivery: HCS and specialist professionals may contribute. The responsible professional, scope and reporting arrangements are confirmed before an appointment is accepted.; Starting information: Property address, premises type and the reason the certificate is needed.), our consultancy ensures that property owners, lenders, trustees, managing agents and legal advisers receive clear, actionable advice rather than generic template commentary.

A recurring technical question when scoping epc & dec certificates is: Does HCS produce the certificate itself? In practice, the certificate is produced by the appointed assessor with the appropriate accreditation. HCS coordinates the enquiry, records and appointment. This preserves the distinction between certificate production and HCS's separate building-side MEES and energy advisory role. Likewise, clients frequently ask: Do I need an EPC or a DEC? Tell us the premises type and why the document is required. EPCs and DECs have different purposes and evidence requirements. A DEC concerns operational energy performance for the relevant public-building context; the assessor confirms the correct route for the instruction. During our pre-instruction triage, we cross-reference existing lease plans, planning and building control histories, operations and maintenance manuals, and prior survey records against the physical access available on the day of inspection. Any limitation—such as occupied rooms, fixed floor coverings, unvented voids, live mechanical plant or high-level roofs requiring MEWP or drone deployment—is identified upfront so the written terms of engagement record what will be inspected directly, what relies on third-party certification and what specialist follow-up may be required.

Every report produced under this service line separates verified physical observations from reasoned professional inference and client-supplied assumptions. Where defects, regulatory non-compliances or valuation/cost sensitivities are identified, we set out the underlying mechanism, the practical risk of deferring action, the statutory or lease implications, and a logical sequence of next steps. You can also review our published London surveying and consultancy projects and our RICS inspection and reporting methodology to see how we structure technical evidence across period, commercial and higher-risk residential assets.

Clear RICS role separation governs how epc and dec certificate coordination in london connects to downstream design, planning or remedial works. Where a client instructs Hampstead Chartered Surveyors to prepare an independent specification and administer an externally tendered JCT contract, we act strictly as impartial consultant. Where, following a completed survey or technical assessment, a client instead prefers a single joined-up design, planning and build team, we can coordinate a seamless handover to our sister practices Hampstead Architecture & Planning (planning permission, conservation and listed-building consents, and technical drawings) and Hampstead Renovations (turnkey refurbishment and building works backed by £5M public liability, £10M employers’ liability and contractors’ all risks cover alongside Hampstead Chartered Surveyors’ RICS-regulated Professional Indemnity Insurance (PII)).

Frequently Asked Questions

Practical questions before an instruction

Scope, access and responsibilities are confirmed in writing for the property and purpose of the instruction.

Does HCS produce the certificate itself?

The certificate is produced by the appointed assessor with the appropriate accreditation. HCS coordinates the enquiry, records and appointment. This preserves the distinction between certificate production and HCS's separate building-side MEES and energy advisory role.

Do I need an EPC or a DEC?

Tell us the premises type and why the document is required. EPCs and DECs have different purposes and evidence requirements. A DEC concerns operational energy performance for the relevant public-building context; the assessor confirms the correct route for the instruction.

Can I use an existing certificate?

Check the official energy certificate register first. Whether the existing document meets your present need depends on the property, its details and the purpose. Send the certificate and explain any alterations or changes since the assessment.

Will recommended works definitely improve the rating?

A recommendation is not a guarantee of the score achieved by a future assessment. The appropriate assessor and design team should evaluate the evidence and proposed measures. Repair condition, moisture, heritage constraints and the way the building is used also matter.
