Why Gas Safety Matters
Compliance That Actually Protects People
It's easy to think of a gas safety certificate in Portsmouth as paperwork — something a landlord needs for legal reasons, filed away and forgotten until the next renewal date. In practice, it's the document that confirms nobody in that property is breathing in carbon monoxide they can't smell or see. Dv Plumbing and Gas Services treats it that way every time, which is part of why we've built up 40+ years of combined plumbing and gas industry experience carrying out gas safety inspections across the city.
We're a family-run Portsmouth business, and every engineer carrying out a gas safety check in Portsmouth is a Gas Safe registered engineer — fully qualified and insured, working to a genuinely safety-first approach rather than rushing through a checklist. That applies whether you're a landlord needing a routine annual gas safety check, or a homeowner who's simply noticed something isn't quite right with a gas appliance.
What's Included
What Does a Gas Safety Inspection Include?
A proper gas safety inspection in Portsmouth isn't a quick glance at the boiler. As gas safety specialists, our engineers work through a structured set of checks on every visit:
Gas appliance testing on every connected appliance — gas boiler, gas cooker, gas fire, and any others present in the property
A check of each flue for correct operation, blockages, and safe termination
Ventilation assessment to confirm appliances have adequate airflow to burn safely
Carbon monoxide detection and a documented carbon monoxide risk assessment
A check of gas pressure and burner performance against manufacturer specifications
Visual inspection of pipework and connections for visible faults or unsafe installation
Issue of a CP12 certificate (the formal gas safety certificate) once everything passes
Who It's For
Who Is This Service For?
Gas safety work tends to fall into one of a few clear situations:
Homeowners
A suspected gas leak, the smell of gas in a property, or simply wanting peace of mind that an unsafe gas appliance isn't quietly putting the household at risk
Landlords
A landlord gas safety certificate is a legal requirement under UK gas safety regulations, renewed annually, and landlord compliance failures carry real legal and financial risk
Property Buyers
A gas safety inspection before selling a property reassures buyers, and a gas safety check before renting a property is required before a tenancy can legally begin
Property Managers
Landlords and agents juggling multiple rental property gas inspections across different renewal dates, where property portfolio support makes compliance far less stressful to track
Process
How Our Process Works
We've kept the process straightforward for both landlords and homeowners:
01
Booking
You tell us how many gas appliances are on the property and whether it's a renewal or a first inspection.
02
Engineer Attendance
A gas safe registered engineer arrives with calibrated testing equipment for every check listed above.
03
Full Inspection
Each appliance, flue, and ventilation point is tested and the results recorded as we go.
04
Clear Reporting
You receive a detailed safety report, not just a pass/fail — useful for landlords who need to show tenants or agents exactly what was checked.
05
Certificate issued
Assuming everything passes, your CP12 certificate is issued on the spot, with a fast CP12 certificate turnaround when paperwork is needed quickly for a tenancy start date.
06
Annual Reminder
We can add the property to our annual reminder service, so the next renewal date doesn't catch you out.
Pricing
Transparent Pricing, Every Time
Pricing for a gas safety check in Portsmouth depends on a few practical factors:
Number of appliances – a single-boiler flat costs less to inspect than a house with a gas boiler, gas cooker, and gas fire all connected
Property type – domestic inspections are generally quicker than commercial properties with multiple connection points
Renewal vs. first inspection – a first-time inspection on an older or unfamiliar system can take slightly longer than a routine annual renewal
Turnaround Required – a same-day gas safety check for an urgent tenancy deadline is handled differently from a scheduled annual visit
We always confirm transparent pricing before the engineer attends, and for landlords managing several properties, we can quote across a portfolio rather than property by property.
