Sound Insulation Testing for new or refurbished dwellings

In compliance with Part E of the Building Regulation in London and nationwide, we actively encourage clients to seek our services at the earliest opportunity.

It is possible that the noise mitigation measures required in some instances, could dictate significant changes to external and internal layouts. Therefore our early involvement could remove the need for costly revisions.

As part of our service in London we can also offer advice on the additional requirements of Approved Document Part E including the control of reverberation in common areas and the performance of internal walls and floors.

E2 Consultants in London are specialists in the provision of high quality and practical acoustic consultancy to both the public and private sectors; typically working with residential and commercial developers, architects, planning consultants, industry, local planning authorities and environmental services.

Our consultants at London can guide you through the process to ensure the best possible chance of achieving sound test passes. Call 020 3390 0301 or email
