A SAP (Standard Assessment Procedure) is there to assess the CO2 emissions, energy costs and thermal performance of your home. This figure will then be incorporated in your OCEPC.

OCEPC’s are issued once construction has been completed. These are for new builds, renovations, and change of use. You will notice on your OCEPC there is a section titled ‘Recommendation Report', this will give you advice on where improvements can be made. You need to remember, the more energy efficient your build is, the less it will cost to run. So, it is not only more environmentally friendly, but it also saves you money.

As stated above, there are two stages to SAP Calculations. Design Stage SAP, which is completed, you guessed it, at the design stage. It is during design when it is best to employ an SAP Assessor to ensure you’re on the right track. Our Assessors at ATSPACE know what works, and what doesn’t. They know the tricks of the trade, and they have extensive knowledge and experience to pass on. If you don’t meet the regulations here, it could be a costly fix. Everything is always harder to rectify in retrospect. The next stage is As Built. Now, this again is as it sounds; undertaken once it has been built. Assuming you’ve taken the guidance at the early stages, this is really just a formality. This will ensure your build performs exactly as it says on the Design Stage SAP. 

The EPC is the output from the As-built SAP calculation displaying the energy performance of the new build dwelling.

ATSPACE has completed over 27,000 EPC certificates, so we have the experience, expertise and confidence to lead the way! We are your one-stop-shop for Building Compliance!

An OCEPC (On Construction Energy Performance Certificate), sometimes referred to as a simple EPC (Energy Performance Certificate), measures the energy performance.

An OCEPC can only be produced from an SAP (Standard Assessment Procedure). By gathering your Build specification and with a set of scaled plans we have the tools to produce your OCEPC with recommendations to achieve your 1st time pass.

There are two stages to SAP Calculations:

  • • Design Stage SAP

  • • As Built SAP

With over 22 year’s experience in developing my own properties and being an approved SAP assessor we have a proven knowledge and process to assist our customers with Cost saving exercises especially when materials are at an all-time high or if a better performing home is required such as carbon negative or better, we have the EXPERT Energy team on hand to assist.

We pride ourselves on the following attributes:

  • • 91% First Time Pass Rate

  • • 72% Returning Customers

  • • Highest Google rating in our industry

I am determined to ensure ATSPACE is the go-to compliance company in the UK. We have a constant supply of free informative information on our blogs or vlogs, so give us a follow on any of the social media platforms.

If you have a question, ATSPACE will answer it!

What Is Thermal Bridging?

Thermal bridging is when heat travels across a material that's more conductive than the materials around it. But what does this mean for your build?

What Are PSI Values?

Psi values measure the heat loss along a meter of junction between two thermal elements. But how do you understand them in your build?

Who Needs An OCEPC?
