Want to join the TMCA?
In 2026, the TMCA developed a new membership structure, marking a shift in how we represent & engage with the traffic management sector.
We introduced a clearer, role-based structure that reflects what organisations actually do within the sector. This new structure has updated categories of membership.
They are:- TM Contractor: Organisations whose primary business is delivering temporary traffic management directly to clients (they may have smaller sub- divisions in other disciplines)
- Managed Service / Labour Provider: Organisations providing labour, crews, or managed service arrangements to TM Contractors, rather than direct NHSS TM delivery to end users
- Product Manufacturer: Organisations that design and manufacture physical TM products, technology, vehicles or equipment used by TM contractors
- Service Provider: Specialist services supporting TM delivery (for example design, lining, training, compliance)
- Start-Up: Early-stage organisations (typically under 2 years trading) operating in any of the above areas
- Multi-Discipline Organisation: Organisations who deliver NHSS TM within their organisation, but their primary business is not TM delivery (for example utility or infrastructure organisations)
Fee Structure
Annual fees linked to organisation size, using turnover bands.
Company size will be assessed on a two-year lag basis.
Pricing Model
| Organisation Size (Turnover) | Annual Membership Fee |
|---|---|

| Small (Between £1m and £15m) | £1,500 |
| Medium (Between £15m and £54m) | £2,000 |
| Large (Between £54m and £250m) | £2,500 |
| Multi-Discipline/Very Large (Over £250m) | £3,000 |

TMCA has a one-off application fee of £250, payable on submission. This is non-refundable and covers:
- Due diligence

- Committee review time
Membership Engagement Levels & Fee Incentives
As an enhancement to the membership structure, the TMCA has introduced engagement levels to recognise and reward meaningful participation in association activity.
All members will join at Bronze engagement level by default, with higher levels earned annually through measurable engagement.
This approach supports increased participation, higher standards of discussion, and greater value for engaged members.
Engagement Levels
| Engagement Level | Criteria | Discount |
|---|---|---|
| Bronze | Default on joining | 0% |
| Silver | Attend either the Annual Conference or Annual Workshop and ≥50% of TMCA Forums | 10% |
| Gold | Attend both the Annual Conference and Annual Workshop and ≥75% of TMCA Forums | 20% |
| Platinum | Organisation has a representative on the TMCA Committee | 20% |
So, status cannot be bought. It must be earned.
By linking future membership discounts to demonstrated involvement, the TMCA is reinforcing a culture where active contribution is valued over passive affiliation.
Key Points
- Discounts apply to the following membership year and must be re-earned annually
- Discounts are applied per organisation
- Platinum reflects governance contribution rather than additional attendance
