We produce SAP calculations which will include the TER and DER Carbon Emission calculations required by Building Control for new dwellings. Included with the SAP calculation is the Energy Performance Certificate, a mandatory requirement for all newly created houses. Our fee will depend upon the complexity of the project but are generally £250 (No VAT payable) Please note that this includes design advice should the dwelling fail the initial calculation and any changes made during the construction - other companies may charge you for this! Substantial discounts are given for repetition of similar house/flat types . SBEM calculations can also be arranged for you.

We are also able to arrange a full Approved Inspector Service undertaken by Meridian Consult Ltd. Providing a one to one service with Architects, Builders and the Public.
