Gas Safety vs Plumbing Safety: What Landlords Must Check

Two Different Obligations — Don't Confuse Them

Gas safety and plumbing safety are closely related but governed by entirely different legal frameworks — and both matter if you're a landlord in Peterborough. Most landlords understand their gas obligations. Far fewer are clear on what they must do for plumbing. Here's the full picture.

Gas Safety: Legally Required, Annually

Under the Gas Safety (Installation and Use) Regulations 1998, you must arrange an annual inspection of all gas appliances, pipework, and flues in your rental property. This must be carried out by a Gas Safe registered engineer, who issues the CP12 Landlord Gas Safety Record. This certificate must be given to existing tenants within 28 days and to new tenants before they move in. Failure to comply is a criminal offence — and critically, it means you cannot serve a Section 21 eviction notice until the certificate is provided. Our gas safety team covers all PE postcodes. See the cost of a gas safety certificate for current pricing.

Plumbing Safety: No Certificate Required — But a Real Legal Duty

Unlike gas, there is no statutory annual plumbing certificate. But under the Landlord and Tenant Act 1985, you are legally required to keep all water supply, drainage, and heating installations in repair and proper working order throughout the tenancy. This duty cannot be transferred to the tenant. A landlord who ignores reported plumbing disrepair is liable for resulting damage and potential personal injury claims.

Legionella: A Documented Legal Duty

The Control of Substances Hazardous to Health Regulations require landlords to carry out and document a Legionella risk assessment. For most standard residential properties, this is a straightforward self-assessment — but it must be in writing. Properties with cold water storage tanks or hot water stored at intermediate temperatures carry a higher risk.

The Practical Approach

The most efficient way to manage both obligations is to combine your annual gas safety check with a broader heating and plumbing inspection in a single visit. Our landlord services team carries out CP12 certificates alongside boiler servicing and plumbing checks — giving you documented evidence of compliance across both areas with one appointment.

Gas Safety: The Legal Framework

Gas safety in rental properties is governed by the Gas Safety (Installation and Use) Regulations 1998. These require landlords to ensure all gas appliances, flues, and associated pipework are maintained in a safe condition and inspected annually by a Gas Safe registered engineer. The resulting Gas Safety Record (CP12) must be retained for at least two years and provided to tenants.

Non-compliance is a criminal offence. The Health and Safety Executive (HSE) enforces gas safety legislation and can prosecute landlords who fail to meet their obligations. Penalties include unlimited fines and custodial sentences.

Plumbing Safety: What the Law Requires

Plumbing safety for landlords is covered primarily by the Landlord and Tenant Act 1985, which requires landlords to keep in repair and proper working order the installations for water supply, drainage, sanitation, space heating, and water heating. This means landlords must respond to reported faults promptly and ensure that communal plumbing — particularly in HMOs — meets minimum standards.

The Water Supply (Water Fittings) Regulations 1999 impose additional obligations, including the requirement to prevent contamination of the mains water supply through correct use of backflow prevention devices and the proper installation of all water fittings.

Practical Differences Between the Two

• Gas safety has a mandatory annual inspection with a certificate. There is no equivalent legal requirement for an annual plumbing inspection, though it is strongly advisable.
• Gas safety is enforced by the HSE and local authorities. Plumbing obligations are primarily enforced through civil law, although serious water system failures can also attract regulatory attention.
• Gas safety failures carry criminal penalties. Plumbing failures are more likely to result in civil claims from tenants, but persistent disrepair can also lead to prosecution under housing health and safety regulations.

The Case for Annual Plumbing Inspections

While not a legal requirement in the same way as gas safety checks, an annual plumbing inspection makes sound financial and practical sense. Catching a slow leak under a bath, identifying a failing stop valve, or spotting early signs of pipe corrosion before it becomes an emergency saves landlords money and protects the fabric of their investment.

Many Peterborough landlords combine gas safety checks and plumbing inspections in a single annual visit, reducing both cost and disruption to tenants. Contact our team to discuss a combined annual landlord inspection covering boiler servicing, gas safety, and a plumbing condition report.

Plumbing Safety: The Landlord's Legal Obligations

While gas safety has a specific annual certificate requirement, plumbing safety obligations for landlords are broader and less precisely defined — but equally enforceable. Under the Landlord and Tenant Act 1985 (Section 11) and the Homes (Fitness for Human Habitation) Act 2018, landlords must ensure that the property's water supply, drainage, and sanitary facilities are in proper working order and that the property is fit for human habitation throughout the tenancy. This means landlords must respond to plumbing faults reported by tenants within a reasonable timeframe (typically 24 hours for emergencies, 7 days for non-urgent repairs) and must carry out proactive maintenance to prevent hazards from developing.

Legionella: A Specific Plumbing Safety Duty

Landlords have a specific duty under the Control of Substances Hazardous to Health (COSHH) Regulations to assess and control the risk of Legionella bacteria in the hot and cold water systems of rental properties. Legionella bacteria multiply in warm water (20–45°C) and in systems with stagnant water or scale and debris build-up. For most domestic properties with a combi boiler and direct mains-cold water supply (no storage tanks), the risk is low, but a written risk assessment is still required. Properties with cold water storage tanks or vented hot water cylinders — more common in Peterborough's older housing stock — require more detailed assessment and temperature monitoring.

Practical Steps for Landlords

Book an annual combined CP12 and plumbing inspection to cover both gas and plumbing compliance in a single visit. Keep records of all maintenance work carried out — date, description of work, and the engineer's contact details. Respond to tenant-reported plumbing faults promptly and in writing. Inspect accessible pipework and drainage at each tenancy change. Call 01733 797074 for landlord compliance packages covering all PE postcodes in Peterborough.

Documenting Compliance

Keeping clear records protects landlords in the event of a dispute or enforcement action. Maintain a compliance file for each property containing: copies of all CP12 certificates (minimum 2 years), boiler service records, any plumbing repair invoices with dates and descriptions, the Legionella risk assessment, and correspondence with tenants about maintenance requests and responses. If a local authority housing officer or environmental health officer carries out an inspection, having well-organised documented compliance significantly reduces the likelihood of enforcement action. A landlord who can demonstrate proactive, documented maintenance is treated very differently from one who cannot produce any maintenance records.
