Welcome to Thermal Acoustic Solutions

On 1st October 2010 the requirements of Part L of building regulations changed. This was to further improve the energy efficiency of all new homes by another 25% above Building Regulations Part L 2006. It is statutory that you are able to show either local authority or an approved inspector that not only do your design proposals comply but the ‘as built’ home complies also with an air pressure test.


On 27th February 2008 the government confirmed a mandatory rating against the code would be implemented for new homes from 1st may 2008. The code replaced Eco Homes from April 2007 and introduced minimum standards for energy and water efficiency at every level of the new national standard.


Part E of the building regulations ‘Resistance to the passage of sound’ supplies legislation's to improve acoustics and therefore sound privacy between residential dwellings. Also covered are common areas such as hotels, hostels, residential homes, schools and hospitals to name a few.


Part B of the Building Regulations ‘Fire Safety’ considers aspects of fire safety in the construction of buildings. Requirements and guidance cover:


  • means of escape in case of fire
  • fire detection and warning systems
  • fire resistance of structural elements
  • fire separation
  • protection
  • compartmentation and isolation to prevent fire spread and conflagration
  • control of flammable materials
  • access and facilities for fire fighting

Part G of England and Wales Building Regulations covers water use and sanitation. It was updated in April 2010 to include a new section on water efficiency. In order to comply with this change, all new houses submitted to planning after 5th April 2010 must be shown to use less than 125 litres of water per person per day. This can be proven by completing a Water Usage Calculation.

We are able to carry out this calculation for you. We will send you our calculations to show compliance with Section 17K of Part G. You are required to produce a Water Usage Calculation for each house type.

From October 2010, the results of this calculation will have an effect on your SAP Calculations and could affect your Energy Performance Certificate rating. If your development is being built to the Code for Sustainable Homes standard, your water limit could be as low as 80 litres per person per day.

We will make all of the necessary arrangements for your Part G Water Efficiency Report and Part L SAP Energy Calculation.


Around 40% of the UK’s energy consumption comes from the way our 25 million buildings are heated, lit and used. Even a minor change in energy performance and the way we use each building can have a significant effect in reducing energy consumption, and therefore carbon emissions.


Communities and Local Governments are leading the introduction of a number of energy and cost-saving measures to make all our buildings more efficient. These measures are being applied across all European Union countries and are in line with the European Directive for the Energy Performance of Buildings.


We at Thermal & Acoustic Solutions can offer services that will assure achieving compliance is a smooth and hassle free process with regard to Part L, Part B and Part E of Building Regulations.
