Welcome to Thermmark

Thermmark is the UK’s leading thermoplastic road marking supplier and installer. We are experts in thermoplastic road markings, playground markings, and decorative public space markings.


Thermmark is an industry expert in thermoplastic road, playground, and safety markings with years of experience working with both the public and private sector. With all this experience across many industries, we have a deep understanding of the needs, challenges and requirements of our customers.

We’re proud to be named in Forbes Solicitors’ Top 50 Most Resilient Businesses, have gained a Prestige Award for Specialist Signage Business of the Year, and were named an International Business of the Year finalist by the Federation of Small Businesses — all awards that we’ve worked incredibly hard for and are proud to have won.

From our base in the UK, we supply thermoplastic to playground and road markers across the country, and around the globe. From Europe to Australia, our markings have travelled the world. Our pre-cut markings are precision made using water jet technology.

The process we use to manufacture markings means that our products get to you in one layer, meaning they can be installed in no time – and we don’t use any third-party ingredients like glue.

Because we manufacture all our plastic in-house, we have the widest range of pigments in the industry, meaning we can create vibrant, fun designs that won’t fade for a long time.

Playground Markings have come along way since the humble outline hopscotch. Our design team combined with our water jet cutting capability make all sorts of weird and wonderful markings possible. From bespoke logos to bringing your own ideas to life, it is all possible! Our focus is to speed up the installation process by creating quick to install, innovative playground markings, no matter how complex they are – with our playground games you don’t have to worry about centring numbers, losing pieces, or building the design.

Like playground markings, with the advent of quality thermoplastic sheet materials it is now possible to bring colour and vibrancy to once drab roads. Colourful road markings help to draw the eye which in turn will save lives by grabbing the attention of the general motorist alerting them to potential hazards. Companies all around the world work with us because our products are simply better to work with, last longer, and are more customisable!
