It states what was inspected, the results of the tests, and whether anything was found to be at fault or unsafe. Every new boiler installation we carry out includes a FREE Gas Safety Certificate. ### Who it is for Homeowners who want documented proof their appliances are safe, buyers and sellers during a property transaction, landlords and letting agents meeting their legal duties, and anyone who has just had gas work carried out and wants the installation verified. ### When you need it Annually for rented property as a legal requirement, when buying or selling, after any significant gas work, when moving into a property with an unknown maintenance history, or whenever you smell gas, see sooting or staining near an appliance, or have symptoms that could point to carbon monoxide. ### Why it needs a registered engineer Gas appliances fail quietly. A partially blocked flue, a cracked heat exchanger, inadequate ventilation or a slow gas leak produce no obvious symptom until they produce a serious one. The inspection exists to find those conditions with instruments rather than by consequence, and only a Gas Safe registered engineer can lawfully carry it out and certify it.

Its early symptoms resemble flu, and the appliance producing it usually appears to be working normally. - A blocked or leaking flue can spill combustion products directly into a living space, and a room-sealed appliance with a failed case seal does the same. - Undetected gas leaks on old pipework or at appliance connections are both an explosion risk and a cost you keep paying on the meter. - Inadequate ventilation for an open-flued appliance changes how it burns, and not for the better. - For landlords, letting a property without a current gas safety record is a criminal matter, not an administrative oversight, and it undermines your position entirely if an incident occurs. ### Mistakes we are called out to fix - Assuming a boiler that is running is a boiler that is safe. - Treating the certificate and the annual service as interchangeable: they are different jobs. - Having only the boiler checked and forgetting the gas fire, the cooker or the hob in the same property. - Relying on someone who is not on the Gas Safe Register, which makes the certificate worthless as well as the work unlawful. - Filing the certificate away without reading the section listing what needs attention. Our process ## How We Carry Out the Work, Step by Step - 1 ### Step 1: Appliance and installation survey We identify every gas appliance in the property, check its location, clearances and installation, and inspect the pipework route and condition from the meter onwards. - 2 ### Step 2: Tightness and pressure testing A tightness test on the gas installation, plus working pressure and gas rate checks at each appliance to confirm each is receiving and burning the correct amount of gas. - 3 ### Step 3: Flue, ventilation and combustion analysis Flue integrity and termination checked, ventilation verified where required, and flue gas analysis carried out with the readings compared against acceptable ranges. - 4 ### Step 4: Safety device verification Flame supervision devices, safety controls and appliance shut-offs tested to confirm they operate as intended. - 5 ### Step 5: Certificate issued and explained The record is completed, issued the same day wherever possible, emailed to you, and to your agent if you want, and anything classified as at risk or immediately dangerous is explained clearly along with what happens next. What you get ## The Difference It Makes ### Documented proof of safety A dated record showing exactly what was tested and what the readings were, for your file, your insurer or a sale. ### Free with every boiler installation Every new boiler we install includes a Gas Safety Certificate at no extra cost. ### Every appliance covered Boiler, fire, cooker and hob inspected together, rather than certifying one and leaving the rest unknown. ### Same-day issue where possible Paperwork completed and emailed the same day wherever we can, so nothing is waiting on us. ### Carbon monoxide risks found by test Combustion analysis and flue checks identify the conditions that produce CO before they produce harm. ### Registered and verifiable Gas Safe registration no. 576059, licence no. 3715984: check us at the door or on the register. In detail ## Gas Safety Inspection Detail A proper inspection is instrument-led. Tightness testing establishes whether the installation holds pressure and whether there is a leak anywhere between the meter and the appliances. Working pressure at each appliance and gas rate measured at the meter establish whether each one is receiving what it needs. Flue gas analysis establishes whether it is burning correctly. Without those measurements, an inspection is an opinion; with them, it is a record you can rely on. Flue and ventilation faults are the most consequential findings. Room-sealed appliances rely on intact case seals and a sound flue to keep combustion products separate from room air, and both deteriorate. Open-flued appliances rely additionally on adequate ventilation and correct draught, and both are frequently compromised by later building work: a new extractor fan, a sealed-up air brick or a replacement window can change how an existing appliance behaves. We check the appliance in the building as it is now, not as it was when it was fitted. Findings are classified rather than described loosely. Immediately Dangerous means the appliance presents an immediate risk and, with your permission, it will be turned off and labelled. At Risk means a defect that could become dangerous, and the same applies. Not to Current Standards means the installation does not meet today's requirements but is not judged unsafe. We explain which category applies, what the practical consequence is, and what putting it right involves and costs, and nothing is disconnected without explaining why first. Landlords should note that the inspection is not the same as a boiler service, though the two are often done in one visit. The certificate is a safety record; the service is manufacturer-scheduled maintenance that keeps the appliance reliable and the warranty valid. Doing both in a single appointment saves a second visit and, in a tenanted property, a second access arrangement. ### Residential and commercial properties We certify domestic properties: houses, flats, HMOs and rental portfolios across Merseyside. Small commercial premises with domestic-type gas appliances can be inspected too, though commercial catering and plant installations fall under a different scope: tell us what appliances are on site when you book. ### Variations of this service - Homeowner gas safety inspection Full inspection and certificate for peace of mind, insurance records or a property sale. - Landlord gas safety record (CP12) The annual inspection landlords are legally required to hold, with copies for tenant and agent. - New installation certification A FREE Gas Safety Certificate issued with every new boiler installation we carry out. - Multi-appliance properties Boiler, gas fire, cooker and hob inspected and recorded together in one visit. ### Materials, parts and equipment - Calibrated flue gas analyser and manometer - Gas tightness testing equipment - Carbon monoxide monitoring equipment - Warning and labelling materials for at-risk appliances - Digital certificate issued by email, with paper copy on request - Gas Safe registration no. 576059, licence no. 3715984 Questions ## Gas Safety Certificate: Frequently Asked Questions How much is a Gas Safety Certificate in Liverpool?We quote a fixed price when you ring, based on how many gas appliances need inspecting. It is free with every new boiler installation we carry out. How long does the inspection take?Around half an hour to an hour for a single appliance, longer where there is a boiler, a fire and a cooker to inspect. Combining it with a boiler service adds time but saves a second visit. How quickly will I get the certificate?Same day wherever possible. We email a digital copy to you, and to your letting agent as well if you want us to. How long is a Gas Safety Certificate valid for?Twelve months from the date of the inspection. Landlords must hold a current record for the property and provide copies to tenants, so it is worth booking slightly ahead of the expiry date. Is a Gas Safety Certificate the same as a boiler service?No. The certificate records a safety inspection of the gas appliances and installation. A service is manufacturer-scheduled maintenance on the boiler that keeps it reliable and keeps the warranty valid. Many customers book both together. What happens if an appliance fails the inspection?We tell you the classification: Immediately Dangerous, At Risk, or Not to Current Standards: explain what it means in practice, and quote a fixed price to put it right. With your permission an unsafe appliance is turned off and labelled, and we explain the reasoning before doing anything. Do you inspect gas fires, cookers and hobs too?Yes. The inspection should cover every gas appliance in the property, and we record each one on the certificate. Do you cover my area for gas safety inspections?Liverpool, Knowsley, Halton and St Helens, including Huyton, Prescot, Whiston, Widnes, Runcorn, Crosby, Woolton and Newton-le-Willows. We answer the phone seven days a week, 8:30am to 5:30pm, and we tell you the same day whether we can get to you. Still not sure? Send us the details or ring 07523 738285.
