The London Landlord’s Essential Checklist: Gas Safety, EPCs, and Boiler Maintenance

The London Landlord’s Essential Checklist

Being a landlord in London is a tough business. It’s a world of regulations, responsibilities, and balancing the books on a major investment. While you’re juggling tenancy agreements and property viewings, one of your most critical legal duties is also one of the most overlooked: the heating and hot water system.

Getting this wrong isn’t just an inconvenience for your tenants; it can lead to hefty fines, invalidated insurance, and in the worst cases, serious legal consequences. As an engineer who works with hundreds of London landlords, this is my straightforward, no-jargon checklist for staying compliant, keeping your tenants safe, and protecting your investment.

1. The Non-Negotiable: The Annual Gas Safety Certificate (CP12)

This is the big one. Let’s be crystal clear: if you rent out a property with any gas appliances (boiler, hob, or fire), you are required by law to have a gas safety check performed every 12 months by a Gas Safe registered engineer.

What is it? A Gas Safety Certificate (also known as a CP12) is the official document that proves all gas appliances, pipework, and flues in your property are safe and in good working order. An engineer will check for gas tightness, ensure correct operating pressures, check for adequate ventilation, and test safety devices.
Why is it critical? Firstly, it’s about safety. Faulty gas appliances can leak carbon monoxide, a silent and deadly poison. Secondly, it’s the law. Failing to produce a valid, in-date certificate can result in huge fines from the Health and Safety Executive (HSE) and even imprisonment. You must provide a copy to your tenants within 28 days of the check.
What it ISN’T: A Gas Safety Certificate is not a boiler service. It is purely a safety inspection. This is a common and costly point of confusion.

2. The Smart Move: The Annual Boiler Service

While the law only mandates a safety check, your tenancy agreement legally requires you to keep the heating and hot water systems in good repair. The single best way to do this is with an annual boiler service.

Why it’s different from a CP12: A service is a deep-dive into the boiler’s health and efficiency. An engineer will clean key components, check for wear and tear, and make adjustments to ensure the boiler is burning gas as efficiently as possible.
The Landlord’s Benefit:
1. Prevents Breakdowns: A service catches small problems before they become a major failure, saving you from a panicked, expensive emergency call-out on a freezing winter’s night.
2. Protects Your Investment: Regular servicing can significantly extend the lifespan of your boiler, delaying the £2,000+ cost of a replacement.
3. Keeps Warranties Valid: If the boiler is under warranty, that warranty is only valid if it is serviced annually. No service history means no free manufacturer repairs.

3. The Pro-Landlord Strategy: Combine and Save

Here’s the tip I give to all my landlord clients: book your Gas Safety Certificate and your annual boiler service at the same time, with the same engineer.

Any good heating company will offer a discounted package for doing both jobs in one visit. This saves you money, involves only one appointment to arrange with your tenant, and ensures you are fulfilling both your legal safety duties and your maintenance responsibilities in one go. It’s the most efficient and cost-effective way to manage your property’s heating.

4. EPC Ratings and the Efficiency Factor

The government is putting increasing pressure on landlords to improve the energy efficiency of their properties. The Minimum Energy Efficiency Standards (MEES) are getting stricter.

An old, inefficient boiler is one of the biggest drains on a property’s Energy Performance Certificate (EPC) rating. If your property has a low rating (D or below), upgrading to a modern, A-rated boiler is one of the most effective ways to boost your EPC score, make the property more attractive to tenants (who are also worried about high energy bills), and future-proof your investment against upcoming regulations.

5. Finding a Reliable Partner, Not Just a Plumber

As a landlord, you don’t just need a plumber; you need a reliable, professional heating partner. You need a company that understands the rental market, can work efficiently with tenants to arrange access, provides digital certificates quickly, and can be trusted to handle an emergency call-out without a drama.

Look for a company that is Gas Safe registered, has excellent reviews (especially from other landlords), and can offer you the combined service and safety check package.
