Quotations Terms & Conditions of Sale

Quotations are valid for 30 days from date of quotation, unless otherwise shown on the quotation document. We will make every effort to avoid any additional costs, and will discuss any changes with you beforehand. Pricing includes the supply of the ducted air circulation system components, installation and electrician costs. Travel is itemised as extra fee. Home Efficiency Group reserves the right to refuse jobs due to construction factors (skillion or kliplok roofs require a specialist roofer for lifting, for instance), location factors (some remote locations are difficult to schedule in a timely manner) or for other reasons at our sole discretion.

Specifically, Home Efficiency Group reserves the right to charge extra for:

  1. Electrical work that takes more than 2 hours (usually 1 to 1.5 hours)
  2. Alterations to the specifications by the customer, or significant oversight or error in the quotation;
  3. Sudden and unexpected price variations from suppliers;
  4. Additional travel that is required outside of a single direct travel to and from the job site;
  5. Unforeseen circumstances that impinge on the timely installation of the service or costs relating to the service;
  6. Unforeseen lath/plaster ceilings & double ceilings etc… which requires greater time to work with & clean-up;

For pricing of non-standard configurations or installations, please contact our sales team on 1300 96 80 60.

LED Downlight Replacements

Home Efficiency Group typically quotes for the upgrade of existing halogen downlights to more efficient LED lights. The scope of work on the HEG quote for LED Downlights includes:

  1. EACH – supply-only of downlight, no labour component.
  2. INSTALL – labour to unplug existing downlight from GPO (socket in roof space), replacement of halogen downlight wth LED version.
  3. PLUG – In the case where a downlight is hardwired into the circuit in a building, this fee includes organising for an electrician to wire in surface socket so that we can plug the downlight in. This fee is in addition to the EACH and INSTALL fee.

In the case where new downlights are required, then HEG presents prices on a Time and Materials  basis. Different configurations, such as dimmers, switches, plates, cabling, integration with meter box, access to downlight locations in the roof space (which may require roof off access) etc… all have an effect on the final price, so a fixed quotation is not practical.

Payment Terms

Most services are 50% deposit, 50% balance upon installation. Payment of invoices must be made on the day of installation following successful testing of the system by the electrician or installation technicians. Payment can be made by Visa,  Mastercard, Cheque, Direct Deposit (e.g. online or phone bank transfer) or cash. The installation technicians will be able to provide a receipt. With solar PV installations, we will test and verify operations of the solar PV system, at which time the balance of the invoice falls due, even though we (by regulation) have to switch the solar PV system off pending the meter being upgraded by a representative of the electrical network provider.


Heat Pump Quotations, Installations, Variations and Upgrades

Quotations are supplied subject to meter box inspection by an electrician at the time of installation. If an upgrade of your meter box or associated wiring is required to be adjusted or upgraded – such as for regulatory or electrical capacity reasons – then the customer acknowledges that this would be additional to the quoted amount and would alter the final invoice as it may require the services of either the electricity utility or a specialised electrician. The customer has the right to cancel the install prior to works commencing if this is the case, but it should be noted that any changes that Home Efficiency Group, or its agents, may require would most likely be required by other heat pump installation companies. Changes to the meter box are generally only required if the meter box is too small to allow new circuit breakers to be installed, or if the meter box is not adequate from a safety point of view, as per current regulations and policies. Often the capacity of the meter box and wiring cannot be ascertained until the meter box has been dismantled or inspected indepth and/or tested.


We respect your privacy – customer details are never sold to 3rd parties. We may contact you from time to time with other home efficiency-related products or services.

Care of installation

All care will be taken with the installation of inlets and outlets in your dwelling. However, if your ceiling construction is “lath and plaster” (which can vary widely in its quality of workmanship) or of poor construction of other materials, then Home Services Group does not take responsibility for damage that occurs from work being undertaken in the normal installation process with requisite due care.

Expectations / Outcomes

As each house is individual in nature (workmanship, air volume, draughts, sub-floor ventilation, insulation, inherent moisture content & other issues) and each household has different patterns of lifestyle use (e.g number of showers taken, temperature of heaters, running times of heaters, etc…), Home Efficiency Group cannot warrant or be held responsible for the effectiveness of the system to distribute heat or alleviate issues (although we try very hard!).

Safety Measures

We proceed on the assumption that the Customer has, or will prior to use of the Home Efficiency Group system, implement adequate safety measures in the use of existing heaters, including, but not limited to, correct wiring, smoke detectors (in all bedrooms, living areas and passageways) and regular servicing of heaters/flues, etc…

Rooftop Solar PV or Rooftop Work with Other Products:

Whilst all due care is taken with tiled roofs, Home Efficiency Group or its agents or contractors accept no responsibility or costs for any broken tiles. Tile replacement is Your sole responsibility. Our installers will replace broken tiles if you have spares, or relocate and provide temporary repair to damaged tiles with silicone. You must replace these tiles to prevent future leaks. We recommend you have spare tiles available on the day of installation so we can replace them for you. Please discuss with our installation manager.

Switchboard, Meters, Electricity Transformer & Grid and Consumer Mains Work

Over and above quoted prices for works in the above categories (switchboard, consumer mains etc), additional fees and pass-through costs may apply from third parties, such as TasNetworks, the meter changeover company or the energy retailer. These charges are often unforeseeable at the time of quotation or works, and are subject to change (i.e. outside of the control of Home Efficiency Group). Payment of these third party fees are the sole responsibility of the property owner. This includes voltage rise adjustments, network charges or compliance fees.

Metering and Tariff Considerations (Asbestos Meter or Switchboard Backing Boards)

Changes to your retail electricity tariffs and/or electricity meters are done by specialist licensed metering electricians. Changing meters is common when you change tariffs, energy retailers or get rooftop solar. Rules associated with the meter box, meters, meter backing board and associated infrastructure can change from time to time. If part of the meter box, particularly the backing board, is made from asbestos, then this may delay swapping over of meters for new smart meters, and may mean that you may incur additional fees (approx $800+GST or more) due to the need for a metering electrician and a TasNetworks technician to arrange a “tee-up” for the swap-over at an arranged specific time.
