Through Installation Support, TMS can provide on-site advice, training and support to identify potential areas where a little more attention, or the adoption of different practices / techniques during the installation stage will ensure both good initial performance and a longer operational life for the system. For example, a UK study identified problems with the jointing techniques often used in lighting installation. However, it also found that by adopting minor changes in the jointing method, which costs very little to implement, the insulation resistance could significantly increased, losses cut, and so result in reduced maintenance costs for many years. Therefore, with rectification work often expensive, the TMS's Installation Support service can prove extremely cost effective. TMS Photometrics implements a policy of strict data confidentiality.
