Company Membership FAQs

What is the difference between a Chartered Building Company and a Chartered Building Consultancy?

A Chartered Building Company is an organisation that physically builds and a Chartered Building Consultancy is an organisation related to the construction process e.g. architects and surveyors.

What is a Training Partnership?

Training Partnerships are a joint venture between a company and the CIOB with the common aim of having a fully trained workforce throughout the construction industry.

How difficult is it to join the CBC scheme?

It should not be hard for a professionally run firm to apply for and be admitted onto the scheme. Any evidence that you will be asked to provide should already be easily to hand.


However, we do expect companies to demonstrate core CIOB values in their operations.  Standards are set reasonably high in order to maintain the prestige of the brand.

Why do you require half of the board to be Chartered?

As a professional institute we recognise the efforts and dedication that it takes an individual to become Chartered.  Naturally we’d like all board members to achieve MCIOB or FCIOB  eventually. For now, we’re accepting a quota of 50% from relevant Chartered built environment institutes of which, 25% must be Chartered with the CIOB.

What other Chartered organisations are accepted?

We accept qualifications from other built environment sector institutes: CABE, CIAT, CIBSE, CIH, ICE,ICES, IStructE, RIBA or RICS. Scottish, Irish and International equivalents are also eligible. 

Can we be a CBC without having any full Chartered members of CIOB on our board?

No. There are no relaxations of the rules that require 25% of the board to be Chartered with the CIOB. 

What happens if a Chartered board member retires?

Retired grades will not count towards the quota for Chartered board directors. This is because CIOB wants to ensure that skills and competencies of each board remain current.


This has two major benefits: as well as ensuring that directors are competent to steer their organisation through the changing legislative climate, the rule incentivises companies to develop future leaders and grow their internal pool of talent.

What happens once we have been admitted to company membership?

You can use the logo and call yourself a CIOB Chartered Building Company or Consultancy.


There are two main requirements for your ongoing membership: You need to complete a form annually when you renew your subscription. You will also be subject to an ‘audit’ visit roughly  every three years.  

When submitting evidence of five policies: Quality, H&S, Equal Opportunities, Environment and Corporate Social Responsibility, how can we get an idea of what is expected of us?

As a CBC you will be expected to have these policies already. Use your professional judgement to submit the existing policies that you are happy with.  We will take into account factors such as size of company when reviewing your application.

What happens if we are unsuccessful in our application?

You will have the opportunity to resubmit. We can advise you on the steps to take to strengthen your application.

Can a subsidiary or regional division of a company become a CBC?

Yes , we actively encourage this.  You must have approval from your head office/parent company and meet the expected requirements.

Will CBC membership automatically qualify me for pre-qualification questionnaires?

Not yet, but this is something we hope to do in the future.

Does our business need to be construction related?

Yes, whether you are a contractor or consultant, your principal activity needs to be related to the built environment sector.

What is the application process and how long will it take?

The first step to your CBC membership is to complete an application form


As part of the application, three references are required. This can take some time, but in our experience, alerting referees that CIOB will be getting in contact can speed up the process.  


Once we have received the references, your application is sent to the Membership Assessment Panel (MAP).


Providing all the necessary paperwork is submitted with the application and depending on the response time of your referees,  the process generally takes around two months.

Who are the Membership Assessment Panel (MAP)?

This is a board of CIOB Fellows who are directors of Chartered Building Companies and Consultancies. They review and audit the processes by which CBC applications are approved. A member of this panel will sign off CBC applications monthly and report into the Employer Engagement Board.

What does it cost?

After the initial joining fee (usually £165), annual membership will be in the range of £200 to £2000. This will be decided on a sliding scale depending on the size of your company or consultancy. Find out more about our fees here.

How and when do I pay?

CIOB will send an invoice once the application has been approved. Please do not send payment until you have received the invoice. We accept payment by credit card, BACS or cheque.
