Total Part L Compliance

At SAPSafe, our goal is to keep the building compliance aspect of your project as simple and straightforward as possible, regardless of how complex the task or timing may seem. We do this by liaising directly with your Building Control Body (whether Local Authority or Independent) to ensure that you have everything that you need when your Building Control Officer comes calling.

SAP - New Build

Any newly built dwelling in the UK is required to comply with Regulations 27 (CO2 Emissions) and 27A (Fabric Efficiency) which make up Part L of the Building Regulations. A SAP assessment is designed to measure compliance in these areas, allowing you to demonstrate compliance where it counts...

 

SAP - Conversion

If a conversion you are carrying out creates any new dwellings either by changing internal layouts or by material change of use, then you will be asked for a Part L1B assessment. This type of SAP assessment measures whether proposed construction types and controlled fittings are in line with minimum efficiency limits...

 

SAP - Extension

Any extension are supposed to have no more glazing than up to 25% of the new floor area. When this isn't possible, a SAP assessment is required to demonstrate (under Part L1B) that the additional heat loss from glazed areas are compensated for by other means (such as improved fabric efficiency)...

 

Air Permeability Testing

For all new build properties, it is a requirement under Part L that an air tightness test is carried out. This also plays an important role in SAP assessments, as uncontrolled air leakage can significantly affect final results from these due to increase heat losses...

 

Water Efficiency Calculations

As part of Part G of the Building Regulations, all new build dwellings must show their efficient use of water for controlled fittings (taps, baths, showers, etc.). On top of being a requirement for Part G, evidence of this is also required as part of a new build SAP assessment...

 

Energy Statements

Due to the introduction of the NPPF (National Planning Policy Framework) more local authorities are adopting the energy requirements set out in the London Plan. This means that planning conditions requiring you to demonstrate a reduction in CO2 emissions through the use of energy efficient build methods and technologies are becoming more common. An Energy Statement is designed to show not only how the baseline Building Regs requirements will be met, but also how the necessary reduction can be made...
