What is BS 99001 certification?
BS 99001:2022 is the British Standard for Built Environment Quality Management Systems. It provides guidance designed specifically for businesses in Great Britain operating within the built environment, including construction, design, engineering, prefabrication and related services. The BS 99001 standard:
- Strengthens the ISO 9001 Quality Management System framework, adapting it to the realities of complex, multi-organisation, project-based environments.
- Ensures quality is embedded at every stage of an asset’s lifecycle, from design and build through to handover, use and decommissioning.
- Provides processes to improve safety, sustainability and compliance with relevant legislative requirements, including the Building Safety Act 2022.
- Is applicable to organisations of every size, from small architectural and design firms to large construction businesses.
The built environment faces increasing scrutiny around safety, quality and accountability. Holding a BS 99001 certified Quality Management System helps organisations demonstrate that these principles are not just aspirational – they are operational.

How to implement BS 99001
ISOQAR is accredited by the United Kingdom Accreditation Service (UKAS), the UK’s government-recognised accreditation body. As all UKAS-accredited BS 99001 certification companies must remain impartial, we can’t help you implement your system if we will also be auditing it.
But don’t worry, we’ve got you covered. Here are the two routes you can use to implement BS 99001 in your organisation:
Use an ISO consultant
There are many consultants available to help you. You can find them on our online database.
A consultant will take you from the beginning right through to certification. Consultants bring a wealth of experience and can share best practice from their work with other organisations.

What is the purpose of BS 99001 certification?
BS 99001 certification provides organisations with a structured framework for managing quality within the built environment. Developed specifically for the construction sector, the BS 99001 standard helps improve project delivery, strengthen collaboration across supply chains and promote consistent quality throughout the lifecycle of built assets.
Is BS 99001 a legal requirement?
No. BS 99001 certification is not required by law. However, it can help organisations demonstrate compliance with relevant regulations and recognised industry best practice. Increasingly, clients and procurement teams are looking for evidence of robust management systems, making certification a valuable advantage during supplier selection and tendering.
Which businesses benefit from BS 99001 certification?
BS 99001 certification is designed for organisations involved in the design, construction, operation, management and maintenance of built assets. It can benefit everyone from contractors and architects to facilities management providers, infrastructure organisations and businesses throughout the wider construction supply chain.
How many BS 99001 certified companies are there?
As BS 99001 is a relatively new British Standard, the number of certified organisations is currently much lower than more established standards such as ISO 9001. Adoption is expected to increase as more organisations across the built environment recognise the benefits of sector-specific quality management.
Is ISO 99001 the same thing as BS 99001?
Although some people refer to “ISO 99001”, there is currently no international standard called ISO 99001. The correct name for the standard is BS 99001. It is a British Standard developed specifically for the UK built environment sector and is not recognised in other countries.
What is the difference between BS 99001 and ISO 9001?
ISO 9001 is the internationally recognised standard for Quality Management Systems and can be applied to organisations in any sector. BS 99001 builds on the principles of ISO 9001 by providing additional guidance tailored specifically to organisations operating within the built environment. It addresses industry-specific challenges while supporting consistent quality management across construction and infrastructure projects.
Is there an international BS 99001 equivalent?
No. BS 99001 is developed specifically for the UK, so there is no direct international equivalent. While ISO 9001 provides the global framework for quality management, BS 99001 offers additional sector-specific guidance that reflects the needs of organisations working within the UK’s built environment.
Do we need to implement ISO 9001 before getting BS 99001?
Yes. BS 99001 is intended to build upon the requirements of ISO 9001, so organisations must therefore have an ISO 9001 Quality Management System in place before they can implement or become certified in BS 99001.
How can BS 99001 certification help with winning tenders?
Many clients are looking for suppliers that can demonstrate recognised quality management practices. BS 99001 certification provides independent evidence of your commitment to quality within the built environment. It can help to strengthen tender submissions by increasing client confidence and differentiating your organisation from competitors.
How much does BS 99001 certification cost?
BS 99001 certification fees depend on factors such as the size of your organisation, the number of sites, the complexity of your operations and whether you already hold ISO 9001 certification. Get in touch with ISOQAR for a tailored quotation based on your specific requirements.
How long does the BS 99001 certification process take?
The timescale will vary depending on how established your existing management system is and whether you’re adding BS 99001 to an existing ISO 9001 certification. Typically, organisations begin by implementing the additional requirements, followed by an independent certification audit. Once any findings have been addressed successfully, certification can be awarded.
Who issues the BS 99001 certificate?
BS 99001 certificates are awarded by independent certification bodies after a successful certification audit. By choosing a UKAS-accredited certification body such as ISOQAR, organisations can be confident that their management system has been assessed against recognised certification requirements.
What should I look for in a BS 99001 certification company?
When selecting a certification partner, look for a UKAS-accredited certification body with experience of the construction and built environment sector. It’s also worth considering the expertise of its auditors, the transparency of its pricing and the level of support provided throughout the certification process. An experienced partner such as ISOQAR can help make certification as smooth and straightforward as possible.
