Building Regulation Drawings

Nearly all types of building work require approval. Typical examples of works that require approval include:-

  • Building a new home

  • Erection, extension or alteration of a building

  • Change of buildings use

  • Internal structural alterations

  • Loft & garage conversions

  • Forming a structural opening; e.g. new window or through room

  • Installing cavity wall insulation

  • Underpinning a house

  • Installing a WC

 

A general rule is that if if the work is structural then it probably requires approval.

SAP Calculations


A SAP rating is the calculation that is required in order to produce a Predicted Energy Assessment and an On Construction Energy Performance Certificate. Building Regulations require that a SAP calculation and a Predicted EPC is submitted for new dwellings prior to the commencement of work. A SAP calculation indicates a score from 1 to 100+ for the annual energy cost based on: - The elements of structure - The heating and hot water system - The internal lighting - The renewable technologies used in the home. The higher the score the lower the running costs, with 100 representing zero energy cost. Dwellings with a rating in excess of 100 are net exporters of energy.
