Can a landlord increase rent after installing a heat pump?

Key Takeaway

Landlords can generally increase rent once every 12 months, provided they give 60 days' written notice. While installing a heat pump to meet Healthy Homes Standards is a landlord's legal obligation, it can also contribute to a property's market rent. Tenants can challenge a rent increase if it is substantially higher than the market rent for similar properties.

Rent Increases After Heat Pump Installation in New Zealand

In New Zealand, the ability of a landlord to increase rent after installing a heat pump is governed by the Residential Tenancies Act 1986 (RTA 1986), along with the Residential Tenancies (Healthy Homes Standards) Regulations 2019. While installing a heat pump is often a legal requirement, its presence can also influence the market rent of a property.

Healthy Homes Standards and Heating Requirements

Landlords in New Zealand have a legal obligation to ensure their rental properties meet the Healthy Homes Standards, which include specific requirements for heating. The Healthy Homes Standards are a set of minimum requirements for heating, insulation, ventilation, moisture ingress and drainage, and draught stopping that rental properties must meet [Source: Residential Tenancies (Healthy Homes Standards) Regulations 2019, reg 3].

For heating, the standards specify minimum heating capacities for living areas. Often, an appropriately sized heat pump is considered the most efficient and compliant heating solution [Source: Residential Tenancies (Healthy Homes Standards) Regulations 2019, reg 6, reg 7]. Landlords were generally required to ensure their properties complied with these standards by 1 July 2024 for all private rental properties [Source: Residential Tenancies (Healthy Homes Standards) Regulations 2019, reg 3].

Compliance with these standards means providing a healthy and safe home for tenants. The cost of complying with such legal obligations is generally considered part of the landlord's expenses in maintaining the property to the required standard.

General Rules for Rent Increases

Landlords must follow specific rules when increasing rent:

  • Frequency: Rent can only be increased once every 12 months for an existing tenancy [Source: Residential Tenancies Act 1986, s 24(2A)].
  • Notice Period: A landlord must give the tenant at least 60 days' written notice of a rent increase. This notice must state the new rent amount and the date from which it takes effect [Source: Residential Tenancies Act 1986, s 24(1)].
  • Fixed-Term Tenancies: For fixed-term tenancies (a tenancy for a specific period of time), rent cannot be increased during the fixed term unless the tenancy agreement specifically allows for it, or if both parties agree to the increase, or if the Tenancy Tribunal orders it [Source: Residential Tenancies Act 1986, s 24(1A)]. If the tenancy converts to a periodic tenancy at the end of the fixed term, then rent increase rules apply.

How Improvements Affect Rent

When a landlord installs a heat pump, particularly to meet the Healthy Homes Standards, it generally improves the quality and amenity of the property. While the law does not explicitly state that a landlord can increase rent because they installed a heat pump, such an improvement can contribute to an increase in the property's market rent. Market rent is the amount of rent that a landlord could reasonably expect to receive for the property, having regard to prevailing market conditions and the rents charged for comparable properties in comparable areas [Source: Residential Tenancies Act 1986, s 25(3)].

A property that is compliant with Healthy Homes Standards and offers efficient heating via a heat pump may be considered more desirable and valuable in the rental market compared to a non-compliant property. Therefore, an increase in rent might be justifiable if the new rent reflects the market rent for properties with similar amenities, including compliant heating.

Tenant's Right to Challenge a Rent Increase

A tenant has the right to challenge a rent increase if they believe it is substantially higher than the market rent for similar properties [Source: Residential Tenancies Act 1986, s 24(4)]. To do so, the tenant must apply to the Tenancy Tribunal within 28 days of receiving the rent increase notice [Source: Residential Tenancies Act 1986, s 25(1)(b)]. The Tenancy Tribunal is an independent judicial body that resolves disputes between landlords and tenants [Source: Residential Tenancies Act 1986, Part 4].

When reviewing a rent increase, the Tenancy Tribunal will consider various factors, including the general level of rents for similar properties in the locality, the condition and location of the premises, and any improvements made to the property [Source: Residential Tenancies Act 1986, s 25(3)]. The Tribunal will assess whether the proposed rent is consistent with market rent. The fact that an improvement (like a heat pump) was a legal requirement does not automatically prevent it from contributing to the property's overall market value and desirability.

When to Seek Independent Legal Advice

Understanding the specific legal obligations and rights related to tenancy can be complex. When specific circumstances arise regarding rent increases, healthy homes standards compliance, or disputes, it is advisable for individuals to seek guidance from official sources.
