What Is Building Compliance?

Residential and Commercial Energy Assessments

Building compliance assessments are required to demonstrate that new builds, extensions and conversions meet UK Building Regulations. These assessments focus on energy efficiency, ventilation and water usage to ensure buildings are compliant, cost effective and environmentally responsible.

We provide building compliance services across London, Essex, Hertfordshire and Cambridge, supporting both residential and commercial projects from planning through to completion.

Building Compliance
SAP Calculations and Assessments

Residential Building Compliance

SAP Calculations, or Standard Assessment Procedure calculations, are used to assess the energy performance of residential properties. They are a legal requirement under Part L of the Building Regulations for new homes and many domestic extensions and conversions.

SAP Calculations apply to:

  • New build houses and flats
  • Self-build homes
  • Domestic extensions and conversions
  • Change of use to residential

SAP assessments demonstrate compliance, calculate predicted energy costs and are used to produce an Energy Performance Certificate (EPC). We carry out SAP Calculations for residential projects across London, Essex, Hertfordshire and Cambridge.

Commercial and Non-Domestic Buildings

SBEM Calculations, or Simplified Building Energy Model assessments, are used for non-domestic and commercial buildings. They demonstrate compliance with Part L of the Building Regulations for buildings that are not classed as dwellings.

SBEM Calculations are typically required for:

  • Offices and retail units
  • Industrial and warehouse buildings
  • Schools, healthcare and public buildings
  • Commercial elements of mixed-use developments

SBEM assessments focus on the building fabric, services, lighting and HVAC systems to confirm energy efficiency targets are met. We provide SBEM Calculations for commercial developments throughout London, Essex, Hertfordshire and Cambridge.

Building Compliance
Water Efficiency Calculations

Reducing Water Usage

Water Efficiency Calculations are required for new residential dwellings under Building Regulations. They demonstrate that water consumption does not exceed the maximum allowance per person per day.

These calculations assess water use from:

  • Baths, showers and taps
  • Toilets
  • Appliances such as washing machines and dishwashers

Water Efficiency Calculations are commonly submitted alongside SAP Calculations for residential compliance.

Building Compliance Energy Statements

Planning and Sustainability Support

Energy Statements are often required at planning stage for both residential and commercial developments. They outline how a project will meet local authority energy and sustainability policies, including carbon reduction and energy efficiency targets.

Energy Statements may be required for:

  • Planning applications
  • Major developments
  • Change of use projects

We prepare clear, policy-aligned Energy Statements for developments across London, Essex, Hertfordshire and Cambridge.

Confirming System Performance

Commissioning ensures:

  • Compliance with approved documents
  • Healthy indoor air quality

Ventilation commissioning reports are typically submitted to Building Control at completion stage.
