I would just like to say, Gas-Tec are fantastic in their service that they provide. Antony was polite and very knowledgable. Tidy and reliable. Well trained with installing the nest thermostats and also working with a wide range of boilers. I would definitely recommend him and gas-tec to friends, family and others. He was quick to identify things and kept all installation neat and tidy. Also happy to provide support and advice in using everything and ensuring the nest system worked well with the home heating. He also set up the installation with future requirements in mind (for example easy removal of device, if moving house etc). He also identified the boiler required a service and he offered it, before carrying out the work, he quickly carried out the work and ensured on logging and certification was completed appropriatly. Keep up the great work Antony.
