A boiler is the heart of any home, providing essential heating and hot water throughout the year. To ensure it remains safe, reliable and efficient, an annual service is highly recommended for homeowners and a legal requirement for landlords. At First Certify, we work with a network of highly skilled Gas Safe Registered engineers to provide comprehensive boiler servicing across Sussex and London, helping you avoid costly breakdowns and ensuring your system operates at peak performance.
Regular maintenance does more than just keep you warm; it validates your manufacturer warranty and ensures that your appliance is not at risk of leaking dangerous carbon monoxide. We facilitate the entire process by connecting you with trusted local experts who prioritise safety and precision.
Neglecting a boiler service can lead to decreased efficiency and increased energy bills. The professional engineers we work with focus on three core areas during every visit:
Safety First: They perform rigorous checks on all internal components to ensure there are no gas leaks or safety risks within the unit.
Efficiency Gains: By cleaning the heat exchanger and checking the burner pressure, they ensure your boiler uses as little fuel as possible to heat your home.
Warranty Protection: Most major boiler brands require an annual service by a Gas Safe Registered professional to keep your multi year warranty valid.
Landlord Compliance: For those managing rental properties, a boiler service is the perfect accompaniment to your annual Gas Safety Certificates CP12.
The independent engineers we partner with follow a detailed checklist to ensure your heating system is in top condition. We pride ourselves on an organised and clean workflow that respects your property.
Visual Inspection: The engineer checks for signs of corrosion or leaks and ensures the boiler is correctly positioned and ventilated.
Internal Component Cleaning: They remove the boiler casing to inspect and clean the main components, including the burner and heat exchanger.
Flue Testing: They use digital analysers to check the flue terminal is clear and that the boiler is burning gas safely and cleanly.
System Pressure Check: They ensure the expansion vessel is at the correct pressure and that the pump is operating as it should.

For residential landlords, a Gas Safety Certificate (commonly known as a CP12) is a legal requirement that must be renewed every twelve months. This document proves that all gas appliances, fittings, and flues within a rental property have been checked by a qualified professional and are safe for use. At First Certify, we work with a network Gas Safe Registered engineers across Sussex and London to ensure your property remains compliant and your tenants remain safe.
Q: How long does an EPC assessment take?
An EPC assessment typically takes less than an hour. However, the duration may vary depending on the complexity of the property’s layout, such as loft conversions, extensions, or other unique features.
Q: Do I need to be present during the EPC assessment?
While it’s not necessary for you to be present during the assessment, it can be helpful to answer any questions the assessor may have about the property. The assessment usually involves a walk-through to gather information about the building’s energy use.
Q: How long is an EPC certificate valid for?
An EPC certificate is valid for 10 years. However, you may want to have your property reassessed sooner if you’ve made significant improvements to its energy efficiency.
Q: Is an EPC required for renting out my property?
Yes, in the UK, an EPC is required for properties being rented or sold. Landlords must provide a valid EPC to tenants at the start of a tenancy. The rating must be at least an E to meet legal requirements.
Q: How long does an EICR assessment take?
An EICR assessment typically takes between 1-2 hours, depending on the size of the property and the complexity of the electrical system. Larger properties with more circuits or older systems may take longer to inspect.
Q: Do I need to be present during the EICR assessment?

Q: What happens during an EICR assessment?

Q: Do I need to be present during the Gas Safety Certificate inspection?
It’s not required for you to be present during the inspection, but it can be helpful if you’re available to provide access to gas appliances, such as boilers, ovens, and gas meters. The inspector will need to check these systems for safety.
Q: Is a Gas Safety Certificate required for rental properties?
Yes, landlords must ensure that all gas appliances in a rental property are inspected and have a valid Gas Safety Certificate every year. This certificate must be provided to tenants at the start of the tenancy and upon renewal of the certificate.
Q: What happens if my Gas Safety Certificate inspection reveals a problem?
