Parry & Partners UK in Manchester and Liverpool our accredited Level 4 Non-domestic energy assessors and provide commercial energy performance certificates for all types of commercial buildings.

The commercial energy assessor in Manchester will need to understand the internal layout of the building and for what purposes it is designed to be used. This is to understand the energy demands of each individual space (zone) in accordance with its designed use.

The commercial energy assessor in Wirral, Liverpool will need to validate (via plans and/or physical survey) zone distances, thermal insulation and building services. The SBEM software will use the information provided by the commercial energy assessor and standard performance tables and will produce the Energy Performance Certificate and Recommendation Report.

If there are no plans for a building, the commercial energy assessor will need to survey the building and gather the appropriate information. If you have up-to date information and plans for your building this process will be less time consuming.

The commercial energy assessor North-West is responsible for ensuring the information used in the commercial energy certificate or energy performance certificate is accurate and, even where detailed plans are available, may need to validate this information by making a site inspection.

Commercial Energy Assessors Wirral, Merseyside will need to be qualified for the type of building being assessed to produce a commercial energy performance certificate. For non-dwelling energy performance certificates, the levels are:

  • level 3 – simple, existing non-dwellings: small buildings such as converted houses or doctor's surgeries (using SBEM)
  • level 4 – new and existing non-dwellings: eg small purpose-built office buildings (using SBEM)

The commercial energy assessor Warrington, North-West will then record the energy performance certificate onto the national register via his or her accreditation body and provide the seller or prospective landlord with the EPC.

    A level 3 building includes frequently occurring characteristics such as simple heating systems, simple natural ventilation and small comfort cooling systems.

    simple heating systems (Boiler Systems up to 100kw)

    small comfort cooling systems (up to 12kw)

    (2 linked boilers of 75kW is level 4).

    Level 4

    Level 4 buildings are all buildings that have any HVAC services that are not defined in the “frequently occurring“ list. In practice the following would be classified as level 4 HVAC:
