Our Gas Safety Certificates Process
Booking
Call 01474 329154 or use the online contact form. We confirm the appointment and advise on what access is required. For tenant-occupied properties, we communicate directly with the tenant if preferred.
Inspection
Our Gas Safe registered engineer attends the property at the agreed time. The inspection typically takes 30–60 minutes depending on the number of appliances and covers all gas appliances, pipework, flues, combustion analysis, gas pressure, and safety devices.
Certificate Issue
On completion, we issue the CP12 certificate documenting the inspection results for each appliance. We provide this to you and, where appropriate, directly to the tenant on the same day.
Remedial Work (if required)
If any appliance is found to be unsafe, we advise on the required action. In many cases we can carry out the remedial work at the same visit or promptly thereafter.
Gas Safety Certificates for Erith Properties
Victorian and Edwardian Terraces with Back Boilers
A number of older Erith properties still have back boilers behind gas fires. These require careful inspection as they can have ventilation issues and are increasingly difficult to source parts for. If we find your back boiler is not safe, we will advise on whether repair is viable or whether the boiler should be decommissioned.
Post-War Semis with Gas Fires
Many properties in Northumberland Heath retain original or early gas fires. Gas fires are among the highest-risk appliances — they rely on adequate room ventilation and intact flues. Our engineers carry out a thorough inspection of gas fires as part of every safety check.
Rental Properties and Conversions
Erith has a significant private rental sector. Properties converted into flats sometimes have gas supply configurations that require careful inspection: boilers serving individual flats, gas supplies that still originate from a meter serving the whole property, or flues from multiple appliances sharing wall penetrations.
FAQs: Gas Safety Certificates in Erith
How much does a gas safety certificate cost in Erith?
Our standard CP12 certificate for a single appliance (boiler) in an Erith property is £85. Adding a second appliance — a gas hob or gas fire — brings the cost to £100. A combined gas safety certificate and boiler service is £140. All prices include VAT.
Can I get a gas safety certificate and boiler service in the same visit?
Yes, and we recommend it. A boiler service and gas safety inspection cover overlapping checks, so combining them is more efficient and cheaper than two separate appointments. Our combined package is £140 for a single boiler and gas appliance inspection.
What if a gas appliance fails the safety check?
If our engineer finds a fault that makes an appliance Immediately Dangerous, they will advise you and, with your permission, disconnect the appliance. You will receive a written report describing the fault. We advise on whether repair is viable or whether the appliance should be permanently decommissioned.
