SAP
SAP Calculations in accordance with Building Regulations part L1A (new builds) and part L1B (extensions and conversions). All SAP Calculations are comprehensive and include U-values, Reports for Building Control, and advice and specifications to ensure compliance. We will work with each project from the design stage all the way to completion to ensure the project runs as smoothly as possible.
RdSAP
RdSAP services, short for Reduced Data Standard Assessment Procedure, provide Energy Performance Certificates (EPCs) for existing residential dwellings. They are used to assess the energy efficiency of homes already built, using a streamlined approach compared to the Standard Assessment Procedure (SAP) used for new buildings. RdSAP assessments are conducted by our qualified Domestic Energy Assessors (DEAs) who evaluate the property’s insulation, heating systems, and other factors to determine an EPC rating.
Minimum Energy Efficiency Standards (MEES)
In the UK, landlords must comply with the Minimum Energy Efficiency Standards (MEES), which set a minimum Energy Performance Certificate (EPC) rating of E for privately rented properties. Since April 2020, landlords cannot let properties with an EPC rating below E unless they have a valid exemption.
However, there are upcoming changes: the government has proposed raising the minimum EPC rating to C by 2030 to improve energy efficiency in rental properties. This means landlords will need to invest in upgrades like better insulation, efficient heating systems, and double-glazed windows to meet the new standards.
Failure to comply could result in penalties or restrictions on renting properties.
Reducing carbon and net-zero
Decarbonising the built environment is an intricate challenge that calls for an integrated approach spanning design, construction, operation, and end-of-life management. A fundamental starting point is to adopt a whole life-cycle perspective. This means assessing emissions not only from operational energy use but also from the embodied carbon in building materials and construction processes. Lifecycle carbon assessments help pinpoint the most impactful intervention points—from selecting low-emission or recycled materials at the outset to retrofitting existing structures with energy-efficient and renewable systems later on .
