Landlord Plumbing Safety Checklist for Rental Properties

The Plumbing Check Every Peterborough Landlord Should Do

Your plumbing and heating obligations as a landlord go well beyond keeping the boiler running. Failing to maintain a safe water and drainage system puts tenants at risk, exposes you to legal liability, and can void your landlord insurance. Use this checklist alongside our landlord plumbing services to make sure nothing is missed.

Annual Legal Requirement: Gas Safety Certificate

The Gas Safety (Installation and Use) Regulations 1998 require an annual check of all gas appliances, pipework, and flues by a Gas Safe registered engineer. The resulting CP12 must be given to existing tenants within 28 days and to new tenants before they move in. Failure to comply is a criminal offence. Our Gas Safe engineers issue CP12 certificates across all PE postcodes and can send you automatic annual reminders.

Before Every New Tenancy

Run all taps and check pressure throughout the property. Confirm the stopcock is accessible, labelled, and turns freely — tenants need to be able to shut off the water in an emergency. Test all drains. Inspect under-sink cabinets for any signs of moisture or slow leaks. Check toilet cisterns and pans for cracks. Test bath and shower seals — failed silicone allows water to penetrate the floor structure silently.

Boiler and Hot Water

Confirm the boiler is serviced and producing hot water at the correct temperature. Between 50°C and 60°C at the cylinder prevents Legionella risk; limiting it to 48°C at the tap protects against scalding where vulnerable tenants are present. Book your annual boiler service well before the tenancy start date so any issues are resolved in advance.

Legionella Risk Assessment

The Health and Safety Executive requires landlords to carry out a Legionella risk assessment. For most standard residential properties with a conventional boiler, this is a simple self-assessment — but it must be documented. Properties with cold water storage tanks, infrequently used outlets, or hot water stored between 20–45°C carry a higher risk and may need professional assessment.

Your Ongoing Duty

Under the Landlord and Tenant Act 1985, you must keep all water, heating, and sanitation installations in repair and proper working order throughout the tenancy. For plumbing emergencies — burst pipes, loss of hot water, heating failure — a same-day or next-day response is expected. Delayed responses that result in damage or risk to health can lead to compensation claims.

Annual Checks Every Landlord Should Carry Out

Unlike gas safety, there is no single legally mandated annual plumbing inspection — but the Landlord and Tenant Act 1985 requires you to keep all water installations in repair and proper working order. An annual check is the most practical way to meet this obligation and identify issues before they become expensive emergencies.

The Essential Landlord Plumbing Checklist

• Stopcock: Confirm the location of the internal stopcock and test that it operates freely. Lubricate if stiff. Make sure tenants know where it is.
• Cold water storage tank (if applicable): Older properties may have a loft tank. Check it is covered, free from contamination, and that the ball valve operates correctly.
• Boiler and heating: Annual service and Gas Safety Check by a Gas Safe registered engineer. Check radiators heat evenly — cold spots may indicate sludge or airlocks.
• Hot water cylinder (if applicable): Check the temperature is set to at least 60°C to prevent Legionella growth. Test the pressure relief valve. Inspect for signs of corrosion or dripping.
• Visible pipework: Look for signs of dripping joints, green verdigris on copper pipe, or rust staining on walls or ceilings — all indicate active or historic leaks.
• Taps and mixers: Test for drips and check that isolation valves under sinks can be turned off.
• Toilets: Check for continuous running (water trickling into the pan) which wastes water and inflates bills. Test flush mechanism.
• External drains: Clear debris from gullies and check that inspection chamber covers are intact and accessible.
• Guttering and downpipes: Blocked or overflowing gutters cause damp penetration and structural damage. Clear annually in late autumn.

Legionella Risk Assessment

Landlords have a legal duty under the Control of Substances Hazardous to Health Regulations 2002 (COSHH) and the Health and Safety at Work Act 1974 to assess the risk of Legionella in the water systems of their rental properties. In most single-occupancy domestic properties, the risk is low and a simple written risk assessment by the landlord is sufficient, but it must be carried out and documented.

HMO Additional Requirements

Houses in Multiple Occupation face stricter standards. Water systems in HMOs carry a higher Legionella risk due to more complex pipework and potential periods of low or no use in individual rooms. An independent Legionella risk assessment by a competent person is strongly recommended for HMOs.

Water Pressure and Flow Rate

Adequate water pressure is a basic habitability requirement under the Homes (Fitness for Human Habitation) Act 2018. A tenant who cannot run a shower at usable pressure, or who finds that pressure drops significantly when two outlets are used simultaneously, has grounds to request repair. Low water pressure in Peterborough rental properties most commonly results from partially closed isolating valves, corroded pipework reducing bore diameter, blocked inline strainers on appliance supply hoses, or boiler flow restrictors. All of these are straightforward to diagnose and repair. Document the incoming mains pressure at the start of each tenancy using a clip-on pressure gauge — this gives a baseline against which future complaints can be assessed.

Drainage and Waste Water Systems

Drainage faults are among the most common tenant complaints in rental properties. Slow-draining baths and basins, blocked kitchen sinks, and gurgling toilet cisterns often indicate developing blockages that will become complete failures if not addressed. Carry out a drainage check at each tenancy change — run all outlets, flush all toilets, and lift and inspect accessible inspection chambers in the garden or yard. Properties with mature trees on or adjacent to the site should have a CCTV drain survey every 5 years to monitor root intrusion in clay drainage runs. Keep records of all drainage maintenance work carried out.

Annual Inspection Checklist Summary

• Gas safety certificate (CP12) renewed annually by Gas Safe engineer
• Boiler serviced annually — service record issued
• All visible pipework inspected for corrosion, leaks, and inadequate support
• Drainage checked — all outlets flow freely, inspection chambers clear
• Legionella risk assessment reviewed or updated
• Water pressure confirmed adequate at start of each new tenancy
• Cold weather pipe insulation inspected — particularly loft and external areas

Emergency Contact Information for Tenants

Provide tenants with clear written instructions at the start of each tenancy: the location of the main stopcock, what to do in a plumbing emergency (how to isolate the water supply), the gas emergency number (0800 111 999), and your emergency contact number for out-of-hours situations. A laminated emergency card kept in the property — near the consumer unit or inside a kitchen cupboard — ensures this information is accessible when needed. Tenants who know how to isolate the water supply in a burst pipe emergency can prevent tens of thousands of pounds of water damage while waiting for an emergency plumber to attend. This simple preparation costs nothing and is good landlord practice regardless of legal obligations.
