Welcome to your new team member

We work with you from pre-planning to post construction to ensure you meet your planning, building regulations and client requirements.

Under Section 25A of the building regulations you are required to review . This report should be submitted to the Local Planning Authority prior any work on site. We recommend getting the Building Regulations 25A report undertaken as early as possible within the design process to ensure that the most cost effective solution is provided.

 Building Regulations 25A

What are the requirements of Building Regulations 25A

Part 25A of the Build Regulations require the “Consideration of high-efficiency alternative systems for new buildings”.

Before construction of a new building starts, the person who is to carry out the work must analyse and take into account the technical, environmental and economic feasibility of using high-efficiency alternative systems in the construction. This should include consideration of the following:

The local authority may require production of the documentation in order to verify that this regulation has been complied with prior to any working starting on site.

Things we consider when looking into the 25A report are availability of technologies, local energy infrastructure and networks and heat maps, space for equipment installation, local environmental issues such as overshading and windspeeds, size of development and costs associated with technologies installation.

How can we assist?

We have a wealth of experience across a broad range of low carbon and renewable technologies, including heat pumps, district heating schemes, combined heat and power. You can be confident that we will suggest the most appropriate, cost effect, technology for your scheme. Our reports are fully compliant with Building Regulations and are accepted by Local Planning Authorities.

If the local planning plan requires full report detailing how the development will meet carbon or energy reduction targets then we can also assist with the completion of a full energy feasibility report. This report look in more detail the suitability of each technologies and how they contribute to an overall reduction in carbon emission or energy usage. All of our feasibility studies include a 25A report as standard.

One we have completed the early stage feasibility studies and agreed a way forward we can complete the full SAP Calculations or SBEM Calculations for your development.
