This is third party content provided by Build Aviator and any links will take you to their website.
Once you have your final plans, next you’ll need to know the cost of the project, the materials you’ll need and what labour and plant costs will be.
Build Aviator offers a comprehensive estimating service and as well as SAP assessments. Submit your plans here1 and tick the services that you’re interested in. Build Aviator will review your plans and let you know how much they’d charge for the service you need. If you’d like to go ahead, press ‘confirm’ on the email or reply ‘YES’ to the text. We will get your estimate booked in. If you choose to have a SAP assessment too, we will ensure the estimate is completed to the requirements of your SAP assessment, ensuring your build is compliant with Government Energy Performance Regulations. View our process video2 to find out more.

SAP Assessments
Standard Assessment Procedure, or SAP as it is more commonly known, is the Government’s method for measuring the energy rating of a building.
SAP calculates a dwelling’s CO2 emissions, along with likely energy costs for space, water heating and lighting per square metre, producing a score between 1-100. The higher the number, the more energy efficient the property is.
Build Aviator SAP Assessment Service takes your plans and provides you with a product specification. We provide a list of materials required, meaning your assessment has been undertaken using actual u-values rather than notional values. This offers a significantly more accurate representation of the energy rating of your dwelling
We ensure all the products listed are locally available saving time with material procurement
We include our Registered Construction Details (RCDs) into your assessment, providing you with build details and points to watch to minimise thermal bridging at junctions. These RCDs have been approved by Local Authority Building Control
Along with a full SAP report, you’ll also receive an on-site support pack containing: a SAP summary, product specification with associated U-values, RCDs and support documents for end of build testing.
