About IllumiDex

Illumidex UK Ltd is a family run company based in Southport but covering all parts of the UK. We have extensive qualified and hands-on experience in producing bespoke large scale festive decorations and lighting schemes.

We continually work hard to establish ourselves as one of the leading festive lighting decoration manufacture and installation companies, offering a tailored and exceptional service to all of our clients, both commercial and residential.

Directors Jan and Steve Clayton are both very proud of our achievements and progression. Illumidex are the ONLY festive decoration installers in the UK to be fully compliant and registered with HERS and NVQ in the installation of christmas decorations. 

Illumidex were delighted and proud to be awarded the Lord Street Southport lighting contract in 2020 which involved the removal of 30,000 metres of failed tree lights and the installation of 30,000 metres of newly designed high specification lights within 80 trees along the one mile stretch. This was and still is the largest single street tree lighting contract in the UK. The impact of this project has been recognised across the country through news channels and press agencies/social media channels and notably by Prime Minister Boris Johnson in the House Of Commons, who said that ‘he wished to visit Southport to see the Boulevard Of Lights which rivalled the Champs Elysees in Paris!’ 

Southport BID, Sefton Council, Sefton Street Lighting and Highways have experienced first hand our passion in the work that we do, hard work and professionalism, proving that we can deliver an exceptional and individual service.
