Inspection and testing of portable electrical appliances
The employer must keep portable electrical equipment safe using a risk-based approach: user checks before use, periodic formal visual inspection and, where needed, combined inspection and testing (PAT). HSE sets no interval and states that blanket annual labelling is often excessive: in low-risk offices visual inspection every 2 years and testing every 5 may suffice, while portable tools on construction sites need cycles measured in months. Applies to all workplaces with plug-in electrical equipment; testing everything is not required, and the risk assessment decides which appliances, in what depth and how often.

Five-yearly EICR in privately rented homes
The landlord must have the fixed electrical installation inspected and tested by a qualified person at intervals of no more than five years, or sooner if the previous report requires it, and obtain an Electrical Installation Condition Report. A copy must be given to each existing tenant within 28 days of the inspection and to new tenants before occupation, and any C1, C2 or FI codes must be remedied within 28 days. Applies to private residential tenancies in England, including HMOs, excluding certain social housing, long-term care accommodation and some resident-landlord lettings; the report must also be supplied to the local authority within 7 days of a written request.

Decommissioning boilers and heat pumps
What triggers this rule is the removal or replacement of the appliance. Where it contains fluorinated gases — typically a heat pump — the refrigerant must be recovered before disposal by personnel holding the qualification required for the activity, and venting to atmosphere is prohibited. The metal body goes to scrap while boards and controls follow the WEEE route. The burden sits with the operator holding the appliance, who keeps the record issued by the technician: it is the only document tying the disposal to a recovery that actually took place.

Annual landlord gas safety check and Gas Safety Record (CP12)
The landlord must have every gas appliance and flue checked by a Gas Safe registered engineer within 12 months of installation and thereafter at intervals of not more than 12 months. The record must be given to existing tenants within 28 days of the check and to new tenants before occupation, and for lettings of 28 days or less it may be displayed; the record must be kept until there have been two further checks. Applies to landlords of residential property with gas appliances, including HMOs, park homes and houseboats, and not to tenants' own appliances, for which the flue duty remains where the flue belongs to the landlord.

Check sentinel outlet temperatures monthly
Sentinel outlets, that is the nearest and furthest outlet from each tank or calorifier, must be identified in the hot and cold water system and their temperature measured every month: hot water must reach 50 degrees within one minute, cold water stay below 20 degrees within two minutes. Calorifier flow and return temperatures are also checked monthly, while cold water storage tanks are inspected annually and records are kept for at least 5 years. Applies to hot and cold water systems in workplaces, hospitality, healthcare and sports facilities; rented homes follow a proportionate regime with no routine microbiological sampling.

Periodic inspection of the fixed electrical installation in commercial premises
The employer must keep the electrical installation in a condition that prevents danger: the recognised good practice is periodic inspection with an EICR issued by a competent person, at a maximum interval of five years for offices, shops and industry and shorter intervals for harsh environments. Evidence is the EICR with the remedial works record. Applies to all workplaces with a fixed electrical installation: under IET Guidance Note 3 intervals vary by use, 5 years for offices and shops, 3 years for hotels and restaurants, 1 year for swimming pools, 3 months for construction sites. Cadence to be confirmed on the cited source.

Review the legionella risk assessment
The duty holder must identify and assess sources of legionella risk in water systems, put a written control scheme in place, appoint a responsible person and review the assessment periodically, and in any event when the system, the use of the building or the occupancy changes, or when checks show the controls are failing. The assessment must be kept while current and for at least two years afterwards. Applies to employers and anyone in control of premises with water systems that can generate aerosols (cooling towers, hot and cold water, showers, spa pools, humidifiers, decorative fountains); residential landlords have proportionate duties over the dwelling's water system.

Maintenance of gas installations in workplaces
The employer or self-employed person must ensure that every gas appliance, installation pipework and flue at a place of work under their control is maintained in a safe condition. Practice, in line with manufacturers' instructions, is annual maintenance by a Gas Safe engineer holding the appropriate commercial qualification; evidence is the maintenance report with the commercial gas safety certificate. Applies to all workplaces with gas appliances, such as offices with a boiler, commercial kitchens, warehouses with radiant heaters and laboratories; commercial kitchens must also have the gas interlock with ventilation checked.

Give the EICR to the tenant within 28 days
A copy of the Electrical Installation Condition Report must be given to existing tenants within 28 days of the inspection and to new tenants before they take up occupation; on written request it must reach the local authority within 7 days. The duty is the landlord's and can be handled through a letting agent without the responsibility moving. The definitive title of the instrument covers both the private and the social rented sector (SI 2020/312): the draft 'Private Rented Sector' version is not the text in force. Keeping evidence of delivery is what makes the duty demonstrable.
