Following the public address by the Prime Minister, we have taken the decision to temporarily close our training centre and rearrange all non-critical training both on and off-site for the remainder of March, April and May. Whilst training is suspended, we are still very much open in terms of queries and bookings. Please do not hesitate to contact us as normal via telephone, email, social media or the online chat facility on our website. All bookings for non-critical training will be honoured and our sales team are currently in the process of contacting affected customers with alternative training dates. If you have any critical training needs over the coming weeks do not hesitate to contact us. Please be aware that this training is being reserved for Key Workers and will only take place if absolutely necessary. All of us here at TL Training are hoping to return to business as normal shortly. However, we must continue to follow the Government’s advice and only re-open when it is safe to do so. TL Training hopes that you and your family stay safe over the coming weeks and months and very much look forward to assisting you with any training requirements you have following this extraordinary time.
