Heat Pump Installation Cost in Richmond

  • Updated 29 Oct 2026

A heat pump is one of the bigger purchases a Richmond homeowner makes, and the quote you get can look quite different from the one your neighbour got. The size of the unit, where the outdoor unit can sit and how much electrical work is needed all move the number.

Quotes vary with the unit and the work involved, so it helps to know what the figures include before you compare offers. The price table is a starting point, not a promise.

What size heat pump do you need in Richmond?

Enter the room size and how well it holds heat for a rough size. An installer confirms it when they measure up.

About 5 kW

A rule of thumb NZ installers use, for a room with a standard 2.4 m ceiling. High ceilings, big windows and open-plan spaces need more, so an installer should confirm it.

How to size a heat pump

What does a heat pump cost to install in Richmond?

The price table gives typical New Zealand installed prices, including GST, for a standard back-to-back install: an indoor high-wall unit with the outdoor unit mounted directly behind it, a short pipe run and the usual wall bracket. It is the simplest job and the least expensive.

Match the unit to the room rather than to the house. A small high-wall unit of about 2.5 kW suits a bedroom or small room, a medium unit of about 5 kW suits a lounge, and a large high-wall unit of about 8 kW suits open-plan living. A ducted system is the option for a whole house. The energy label shows heating at 7°C and 2°C outside and cooling at 35°C, so compare quotes on the same figures.

If the right size is not obvious, the guide to heat pump sizing explains how room size and glazing affect it, and the national heat pump cost guide shows what other regions pay.

What pushes a heat pump quote up or down?

A straightforward job is only the starting point. A longer pipe run between the indoor and outdoor units, awkward access or height for the outdoor unit, a wall that needs a bracket or a floor-level pad, extra electrical work such as a new circuit or a switchboard upgrade, and removing an old unit all add labour and materials. So does a larger unit or a ducted system.

Read the quote closely and ask what is excluded. Under the Fair Trading Act a quote must not mislead, and hidden costs count. If no price is fixed in advance, the Consumer Guarantees Act says you pay only a reasonable price.

How do Richmond's installers compare?

The town has 8 heat pump businesses, and 7 say they fit heat pumps. The trade splits: 3 say they install ducted systems, 2 mention multi-room work and 2 mention hot water heat pumps. Servicing appears on 6 of the websites, and repairs feature for several of them, which matters if you would rather deal with one firm for everything. Four say they give free quotes.

Choice widens nearby. Nelson, about 11 km away, has 16 installers, and Māpua, about 21 km away, has 5. If you want a particular brand or a ducted design, the short drive is worth considering.

The comparison of ducted and high-wall heat pumps helps if you are weighing the two, and the guide to single-room and multi-room systems covers heating more than one room. The heat pump servicing guide explains what a service visit involves.

Paying for a heat pump in Richmond

No finance option is mentioned on the websites of Richmond's heat pump businesses, so ask each one how payment works and whether a third-party payment plan is available.

None of them mentions Warmer Kiwi Homes on their website either, but the scheme is run by EECA and funds heat pumps for eligible owner-occupiers. Eligibility depends on holding a Community Services Card or a SuperGold Combo Card, or on living in a qualifying area. The grants guide explains how to check.

Heat pump cost questions in Richmond

Do I need consent for a heat pump in Richmond?

The district council is the building consent authority for the town, so check with it for your own address before work starts. Ask as well where the outdoor unit may sit, since boundary setbacks can affect the position.

Who should install my heat pump?

Look for a registered electrician if the job needs a new circuit. Two of the Richmond businesses mention a registered electrician on their websites. The guide to who can install a heat pump sets out what to check before you book.

Will a heat pump cope with frosty mornings?

Frosts can occur anywhere in New Zealand, and inland and southern towns see colder winters. Ask the installer how the model you are considering handles defrost, and make sure the outdoor unit sits where it can drain freely and is not boxed in.

What about warranty and dealer backup?

Two of the businesses mention a warranty on their websites, and 1 says it is an authorised dealer for a heat pump brand. Ask what the warranty covers, who honours it, and whether it covers the manufacturer's unit or the installer's own workmanship.
