Build Aviator Assessments & Testing

Build Aviator SAP Assessments


Environmental standards have never been higher in the building industry, so it helps to have our experts take care of your project’s Standard Assessment Procedure (or ‘SAP’ as you probably know it).

Build Aviator offers a complete SAP service to ensure your build meets the Government's method for measuring the energy rating of residential buildings. To comply with Part L1A of Building Regulations, your SAP assessment must be completed and submitted to Building Control before you start work onsite.


Simply upload your plans and we’ll tell you which locally-available products you need, so you can get hold of them quickly and get on with the job in-hand.

Our accredited energy assessor will calculate your build’s CO2 emissions and typical annual energy costs for space, water heating and lighting using accurate u-values, giving you a score between 1- 100. The higher the number, the more energy efficient your property will be.

Your personal expert contact will then give you a full SAP report, complete with our Registered Construction Details (RCDs) which show you where to watch out for thermal bridging junctions, and which products you need to be compliant. These RCDs are all fully approved by Local Authority Building Control (LABC).

Build Aviator Acoustic testing


All new houses, flats and residential rooms must be designed to keep noise (reasonably) contained between rooms within the same building and adjoining buildings.

From planning to completion, noise compliance can cause problems that require time and money to fix. With our help, you can eliminate these costly errors by staying on the right side of regulations.


We’ve teamed up with Local Authority Building Control (LABC) Acoustics to provide comprehensive acoustic testing and one-to-one compliance advice at every stage of your project.

This can include:

•    Environment Noise Risk Assessments during the planning stage
•    Desktop studies to check your plans and details against Part E requirements
•    Advice on material specifications
•    UKAS accredited sound insulation acoustic testing (in line with Building Regs. Part E).

Build Aviator Airtight Testing


All residential new builds need to be tested for air tightness. The test assesses your build’s air permeability rating, which demonstrates Part L compliance to Local Authority Building Control (LABC).

We all know that air leakage is a significant cause of heat loss. So, the less air leakage you have, the more energy efficient your build will be. Your one-to-one contact is on-hand to help you pass first time, giving advice before testing takes places, and providing constructive feedback during testing to help you get that all-important final sign-off.

We work with Local Authority Building Control (LABC) to match our Registered Construction Details (RCDs) with the products you need, giving you a smoother route to Building Control sign-off. This partnership allows us to ensure that you are compliant at every stage of the build process so you can spend less time worrying about meeting building regulations.
