For new residential projects, SAP calculations play a direct role in determining the final Energy Performance Certificate (EPC). The Standard Assessment Procedure (SAP) assesses a dwelling’s expected energy performance using information about its building fabric, heating, ventilation, hot water, lighting and renewable technologies. The completed assessment then provides the data used to produce the property’s…
Failing a sound insulation test can cause delays, remedial work, and retesting as a development nears completion. Often, the cause isn’t the main wall or floor design, but smaller construction details such as gaps, poorly fitted insulation, service penetrations, or flanking transmission, where sound travels around a separating wall or floor through adjoining parts of…
For many homeowners and businesses, solar panels are considered for their potential to reduce electricity bills. By generating some of your own power, you can buy less electricity from the grid and gain greater control over long-term energy costs. However, the environmental impact of solar energy goes much further than financial savings. Solar power can…
Taking on a self-build project gives you the opportunity to shape a home around your own priorities, but it also means navigating several regulatory requirements before the work can be signed off. For a new dwelling, these requirements include meeting the relevant Building Regulations, demonstrating suitable energy performance and obtaining an Energy Performance Certificate (EPC)….
Extending or converting a property can create valuable additional space, but it may also introduce new Building Regulations requirements. One common question is whether SAP calculations for extensions are needed before work begins. The answer depends on the project. Not every extension needs a full SAP calculation, but one may be required where a design…
An Energy Performance Certificate, or EPC, is one of the most useful documents renters can check before agreeing to rent a property. It gives an indication of a home’s energy efficiency, likely running costs, and how easy it may be to keep warm. With planned changes to EPC assessments, renters may soon get clearer information…
SAP calculations are an important part of the building control process for new homes, conversions and some residential projects. They show whether a property meets Building Regulations Part L for energy performance, carbon emissions and energy efficiency. The main reasons SAP calculations fail include poor U-values, inefficient heating systems, weak air tightness, poor thermal bridging, unsuitable ventilation, and…
A non-domestic EPC assessment is a key requirement for anyone involved in selling, renting, or developing commercial properties in the UK. Whether you own a commercial building, manage a business property, or are preparing to let space in the private rented sector, understanding your energy performance certificate (EPC) is essential. An energy performance certificate provides…
Good sound insulation is not just a technical requirement – it’s an important factor in how buyers assess comfort, quality, and overall value. In today’s UK property market, homes that effectively control sound transmission are often seen as more desirable, particularly in flats, terraced housing, and converted commercial buildings. Uncontrolled noise transfer between rooms or…
Creating an airtight building is one of the most effective ways to improve energy efficiency, reduce heat loss, and meet current building regulations such as Part L. Whether you’re working on a new build, a commercial building, or upgrading an existing building, controlling air leakage is key to achieving good performance. Uncontrolled air leaks in…
