Quote & Installation

You’ll then receive a written quotation for your new boiler, including installation. Once you have accepted this, a final survey from a Gregor Heating technical surveyor will be booked in to record exact measurements and any further information needed. Then a Gregor Heating engineer will install the boiler and any related fixtures.


Enjoy Your New Boiler

Once your new boiler has been installed, the installing engineer will also ensure that you are confident with using it by demonstrating how to operate the controls and thermostat. You’ll receive a full parts and labour guarantee for the applicable time period for the model of boiler you have chosen. Now you can just sit back and enjoy your efficient and reliable new central heating system, helping you and your family stay warm and cosy.

Flexible Payment Solutions on Selected Boilers with Gregor

Flexible payment options are available, and eligible customers can now access a competitively priced regular payment plan for selected boilers and spread the cost of their investment in a new boiler through a series of more manageable monthly payments over 1, 3, 5, 8 or 10 years*.

The application process is simple. Finance is provided by Novuna Personal Finance, a division of Mitsubishi HC Capital UK PLC.

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. Also, should you recommend us to a friend for whom we subsequently carry out an installation, we will reward you with a £20.00 Marks and Spencer voucher as a token of our appreciation for your loyalty.
