Important technical information before we arrive

We like to make sure that all of our customers are kept informed of what we might find upon installation. These items are usually covered in your quotation, but we have listed below a few things that you need to know before we carry out your installation.

  1. We will replace your existing heater on a "like for like" basis, so the new unit will almost certainly be kept in the same position as your old one
  2. We may need to alter the base that the unit sits on (the plenum base).
  3. The main ducting around your home will remain the same. This is because it is usually buried in the structure of the property
  4. The existing air supply and return air ductwork will be modified to suit your replacement unit
  5. Replacement quotes do not include replacement grilles and registers unless they have been specifically listed within the quotation. We do of course offer a replacment service
  6. At the time of survey we are unable to carry out a detailed inspection of the flue terminal  or gas ridge vent tile. It may be necessary that additional costs will be incurred if these are found to be defective. Of course we will let you know about any additional works before we carry them out
  7. Your replacement unit may be attached to the existing flue, or we may install a complete new flue system. This will be detailed on your quotation
  8. We will ensure that the gas supply is correctly sized to the warm air unit from the gas meter
  9. We will update and install (where necessary) the correct sized combustion and compartment ventilation to ensure safe operation of your new unit


There are a limited number of items that are excluded from our work as follows

  1. Any decorative work
  2. The stretching of carpets after refitting
  3. The remainder of the system, other than new work
  4. Boxing in on existing installation
  5. Asbestos removal
  6. Alterations to flow and return pipework to the water heater becuase of historic poor installation
