A typical boiler replacement takes a day, and a system conversion upgrade 2-3 days.  All our installations are carried out by our experienced Gas Safe registered engineers (OFTEC-registered in the case of an oil boiler); and all electrical work is carried out by our NICEIC-registered electricians.At the start of your installation, your engineer will talk you through the planned works and discuss any concerns you may have. We will put down dust sheets and take every care to ensure your home is safe and well looked-after.

Having completed the installation, we will commission, test and certify your new installation. We will also carefully talk you through your new boiler’s controls and how to operate it in the most efficient way.  Prior to leaving, we will clear up, vacuum, and leave your home as we found it. We will also leave you with our comprehensive Customer Care Pack that includes operating instructions for your boiler.

Once the installation is complete, we will register the boiler with Gas Safe (OFTEC in the case of an oil boiler) and the manufacturer to ensure the validity of its warranty. You will receive registration certificates from Gas Safe (OFTEC if an oil boiler) and the manufacturer direct to your address.

We will then send you your final invoice, along with a customer questionnaire. We highly value the feedback we receive from our customers; and our questionnaire gives you the opportunity to rate us and make any comments on your customer experience.
