Certified Gas Safe engineers on-site within 1–2 hours for suspected leaks, faults, and gas safety concerns — securing your property fast, with no hidden costs.
A gas leak doesn’t wait for convenient timing. It can start as a faint smell near an appliance, an unexplained hiss near a meter, or a boiler that won’t hold pressure — and it’s not something to investigate yourself. By the time a leak is obvious, the property may already be at risk.
That’s why we treat every call as urgent. Certified Gas Safe engineers attend within 1–2 hours, secure the area, and carry out a full safety audit before anything else happens. Once the source is confirmed, we explain the problem, carry out the repair, and can provide documentation for landlords, insurers, or building management where needed.
Every quote is confirmed in writing before any work starts. No call-out fee, no parking or ULEZ surcharges, no surprises on the invoice. All work is backed by an 18-month workmanship guarantee.
Every job follows the same process, in the same order. We isolate the risk first, then investigate. Here’s what happens when we attend a gas safety call-out.
Rapid intervention to safely shut down the gas supply and eliminate immediate fire or health risks, before any diagnostic work begins.
Rigorous pressure checks across the entire gas installation to confirm there's no undetected leak anywhere in the system.
A full inspection of the gas meter, supply lines, and connected appliances to resolve flow, pressure, or fault issues.
Testing for the "silent killer" to make sure boilers and flues are venting correctly and safely.
Identifying aged or damaged gas pipework that's compromising the integrity of the system.
Confirming appliances have adequate airflow and that exhaust gases are being safely removed from the property.
