Owners and designers of new dwellings or major alterations that need thermal compliance, especially designs where glazing, orientation or slab choices make the rating tight.
A full Nationwide House Energy Rating Scheme (NatHERS) thermal simulation of your dwelling by an accredited assessor, delivering the star rating, stamped plans and certificate needed for National Construction Code (NCC) and Building Sustainability Index (BASIX) thermal compliance. Includes one re-run after design tweaks, so you are not charged again for moving a window.
Often. BASIX thermal compliance can be met by a simple method or by a NatHERS simulation, and larger or glazing-heavy designs usually need the simulation to pass. We tell you before you spend the money.
We advise the cheapest workable changes, usually glazing spec, insulation or sealing rather than redesign, and the included re-run confirms the fix.
Complete drawings with a window schedule, site orientation and construction details. Gaps in the window schedule are the most common delay.
Yes. The stamped plans and specification are compliance documents. Substituting cheaper glazing or insulation on site puts the occupation certificate at risk.
Yes, but multi-dwelling simulation is priced per project. This fee covers a single dwelling.
