Our Building Performance Assessments have been designed to bring clarity to anyone embarking on an individual or collective retrofit projects.

BPA.Lite From £300

A low cost initial assessment of the building, designed to point you in the right direction, and establish the scope of the potential retrofit project.

  • Areas of Concern - Identified during the visual assessment and on receipt of anecdotal evidence provided by the freeholder, leaseholder or their authorised representative.

  • Potential Solutions - That will be described broadly, for example; more insulation required in roof space, more ventilation required in bathroom.

  • Product Suggestions - For example, rigid wood fibre insulation. We will not be specifying particular suppliers of the products.

  • Cost of Works & Potential Annual Saving Estimations - In the form of a low/high range to serve as a guide only.

  • Room by Room Breakdown - Detailing our observations, with emphasis on areas of concern.

  • Valid Current & Post-Retrofit EPC Score - Conducted by a qualified and experienced rdSAP assessor.

  • Current & Post-Retrofit ‘Market Appraisal’ - Conducted by an experienced RICS Registered Valuer and estate agent

The full monty, curated to give you the peace of mind that the retrofit project will deliver exactly as intended with no stone left unturned.

  • Air Tightness Test - Using a Pulse 2.0 which sends a pulse of air around the building at an ambient day to day pressure (4pa), this is essential to determining the air leakage of the building and identify weak points, measured in the form of air leakage rate (Q), air changes (N), air permeability (AP) and effective leakage area (ELA)

  • U-Value Test - Required to accurately determine the existing wall, floor and roof makeup so to specify retrofit works correctly.

  • Thermography Survey - Required to accurately identify excessive cold bridging, continuity of pre-existing insulation and excessive air leakage.

  • Retrofit Costings - Required to approximately determine the financial cost of the retrofit works.

  • Technical Design - CAD drawings focused on specific details around openings and junctures, with emphasis on air tightness, avoidance of thermal bridges and continuity of insulation.

  • Construction Details - Written guidance for tradespeople to accompany the Technical Design.

  • Material Specifications - List of specific materials & products to accompany the Technical Design and Construction Details.
