Electrical Safety Checks Before a Heat Pump in a Rental

The short answer

Fitting a heat pump changes the electrical installation in your rental, so the electrical safety rules for landlords and the heat pump project overlap. Before you commission one, check three things: that the property’s EICR is current and its remedial work is done, that the incoming supply can take the extra load, and that the consumer unit can take a new circuit. Then make sure the installer notifies the network operator and certifies the new work.

How the 5-yearly EICR duty relates to a heat pump

In England, the Electrical Safety Standards in the Private Rented Sector Regulations 2020 require landlords to have every electrical installation inspected and tested by a qualified person at least every 5 years, or by an earlier date if the last report says so. The usual report is an Electrical Installation Condition Report (EICR). Remedial work must be done within 28 days, or sooner if the report says so, and the report goes to the tenant within 28 days of the inspection.

The government guidance says the inspection covers the fixed electrical parts of the home, including the wiring, sockets, light fittings and consumer unit, plus permanently connected equipment and the circuits for specialist equipment such as solar PV and battery storage. A heat pump’s supply circuit is fixed wiring of the same kind, so expect the next EICR to include it.

Three practical links between the EICR and a heat pump:

1. Read the last EICR before you get quotes. Code C1 or C2 items, or a “further investigation” note, should be fixed before new load goes on the installation.
2. Time it. If the next EICR is due soon, having it done first gives the installer an up to date picture of the existing wiring and earthing.
3. The new circuit’s certificate does not reset the 5 years. The guidance only allows an Electrical Installation Certificate to stand in for an inspection, for 5 years, where a home is newly built or completely rewired. A single new circuit is neither.

Supply capacity: can the house take it?

A heat pump adds a significant new load to the supply. The Energy Networks Association (ENA) process for heat pumps starts with the cut-out, the sealed fuse where the network operator’s cable enters the property. Its flow chart notes that:

• cut-out ratings below 60A, such as 30A, 40A or 45A, exist, especially in rural areas
• some homes are on a looped service, where one cut-out serves more than one property, often found on 1970s and 1980s estates, in rural areas and in terraced housing
• the cut-out must not be opened

Where the rating is unknown, the installer asks the network operator. The ENA says operators will never refuse a connection, but work may be needed first. It also says the GB network operators will provide what is needed to decarbonise a home free of charge, up to a 23kVA cable.

The network operator: connect and notify, or apply first

The ENA is clear that the network operator must be told about every heat pump installation. The route depends on the numbers.

Situation	ENA route
Whole-home maximum demand up to 60A per phase, heat pump system up to 32A including boost and immersion heaters, model listed as “Connect and Notify” on the ENA database, no issue with the supply	Connect and notify: fit, then notify
Whole-home maximum demand between 60A and 100A	Apply to connect: the installer applies before installing, and the operator confirms within 10 working days
Heat pump and EV charger fitted together	Apply to connect
Unknown cut-out rating, looped service or other supply concerns	Apply to connect

Installers can submit domestic applications through the ENA’s Connect Direct platform. As landlord, ask to see confirmation that it was done, and keep it with the property records. A heat pump installer check is worth doing at the same stage.

The consumer unit and the new circuit

If the heat pump is wired on a new circuit from the consumer unit, which the installer will confirm, the Building Regulations apply. In England, Part P of the Building Regulations makes three kinds of electrical work notifiable: installing a new circuit, replacing a consumer unit, and adding to or altering circuits in a special location such as near a bath or shower.

Notifiable work is either self-certified by an electrician registered with a government-authorised competent person scheme, or notified to building control before it starts. GOV.UK lists the schemes and says registered electricians appear on a single electrical competent person register.

If the consumer unit has no spare way, is old, or the EICR has flagged it, the installer may recommend replacing it. That is a separate notifiable job and a separate cost, so ask for it to be priced on its own line.

Paperwork to hold after the install

Document	What it covers	Why a landlord needs it
Electrical Installation Certificate (EIC)	The new heat pump circuit, and a new consumer unit if fitted	Evidence the new work was inspected and tested
Competent person scheme self-certification, or building control sign-off	Notifiable work under Part P	Proof the work was notified
Network operator notification or approval	The new load on the supply	ENA requires notification in all cases
Latest EICR	The whole installation	Your 5-yearly duty

The penalty

Councils in England can impose a financial penalty of up to £40,000 for breaches of the electrical safety duties, for breaches from 1 May 2026. That is separate from the energy efficiency rules. The same regulations now also cover the social rented sector, with existing social tenancies to comply by 1 November 2026.

If a tenant refuses access, the regulations say a landlord is not in breach of these duties if they can show they took all reasonable steps, and failing to bring legal proceedings for entry does not count against them on its own. Keep a record of every attempt to arrange access.

When the electrics say “not yet”

• Outstanding C1 or C2 codes. Clear the remedial work first. Adding a heat pump to a faulty installation adds risk and cost.
• A low-rated or looped supply. The network operator may need to do work first. The ENA says timing depends on the work needed, so do not fix an install date until the operator has responded.
• A tight budget. Supply upgrades and a new consumer unit can add to the project. Get them priced before you compare heat pump quotes.

Next step

Once the electrics are clear, run the numbers in the heat pump landlord calculator. If you want quotes that include the electrical work, send an enquiry through the quote page and relevant independent firms contact you, with no charge to you and no obligation.
