Ancillary Services

We also offer a suite of ancillary services, through partnered providers to support our primary Building Control offering.  These can be used in isolation or used in conjunction with each other, so that clients receive a tailor-made service, through one-point of contact to their projects demands.

Energy Assessments

An important part of the Building Regulation Approval process for any new domestic or commercial build is to comply with Part L: Conservation of Fuel and Power.

To support this function, Meridian partner with accredited domestic and non domestic energy assessors to provide SAP and SBEM calculations to help our clients comply with Part L of the Building Regulations. The Energy Assessors will provide detailed and constructive advice on compliance issues and help both the design and construction teams in fulfilling these obligations. On completion of the woks on site, an As-Built calculation and Energy Performance Certificate is produced to inform potential buyers or tenants about the energy performance of the building, so they can consider energy efficiency as part of their investment or business decision to buy or occupy that building. Our partners specialise in providing all types of Energy Certificates on all property types including domestic houses and non-domestic commercial premises.

Air Tightness Testing

If you are building a new domestic or commercial property, it will need to undergo air tightness testing. This assesses the building for ‘air permeability’, checking for air leakage through gaps, holes and other areas.

Our consultants offer on-site air tightness testing throughout the UK for commercial and residential buildings. Our team also provide design stage Air Tightness consultancy.


Sound Testing

Sound testing or also known as acoustic testing, noise testing or sound insulation testing is required for new or converted residential buildings in the United Kingdom. Our partner firms provide efficient sound insulation testing protocols fully comply with Part E of the Building Regulations for England and Wales.

The Acousticians can assist you from the design stage to completion or anywhere in between, ensuring compliance requirements are met sustainably and economically throughout.  We are able to use our extensive network of acousticians to provide optimised acoustic designs for buildings of all types and sizes to achieve and maintain consistent performance levels.


Flow Rate Testing

The requirement to build more highly insulated and airtight buildings means that it is increasingly more important to ensure buildings are not only adequately ventilated but the ventilation system is suitable, balanced & commissioned correctly to ensure its effective and efficient operation.

We are able to test extraction rates and also balance whole-building ventilation systems correctly. This is not only a Building Regulations requirement but is also important to ensure the ventilation strategy is working as cost-effectively as possible.

Building Assessments

We can organise a number of additional services through a Nationwide arrangement with preferred partners. These include:

• BREEAM Assessments
• Thermal Modelling
• Daylight Calculations
• Thermographic Surveys
• Drone Camera Surveys
• Three project summaries
