Gas work done properly, first time

Ring the National Gas Emergency Service on 0800 111 999 straight away. It is free and staffed around the clock. Open doors and windows, turn the gas off at the meter if you can safely reach it, do not touch light switches or use a phone indoors, and get everyone out. Once the supply is made safe, ring us and we take on the repair.

Yes. Every gas job — repairs, installs, servicing, certificates and appliance connections — is carried out by a Gas Safe registered engineer. Ask to see the card at the door. Anybody who hesitates when you ask that should not be touching your gas.

Yes, and Sheffield has a lot of them still in. They sit behind a fire in the chimney breast, so the job takes in the fire and surround as well as the boiler itself, plus making good afterwards. It is a bigger job than a straight swap and we price it as one rather than surprising you halfway through.

Usually it is the boiler protecting itself rather than something dangerous — low pressure, a frozen condensate, a failed sensor, an ignition fault. Resetting once is fine. Resetting it over and over is not, because you are overriding a safety device without knowing what tripped it. Tell us the fault code when you ring.

Yes, and we are set up for them. Multiple appliances, multiple tenants and awkward access are normal on student and shared properties round Crookesmoor, Broomhill and Ecclesall Road. Tell us how many properties and when the changeover is and we will work to it.

Depends on age, which part has failed and whether parts are still made for it. A ten year old boiler needing a common part is usually worth fixing. One needing a heat exchanger, or one that is obsolete, usually is not. We will show you the numbers rather than just recommending the bigger job.

A like-for-like combi swap is usually a day. A back boiler removal, a conversion from a tank system, or fitting a cylinder is more like two to three days. You get the timescale in writing with the quote.

A safety check confirms the appliance is safe right now, which is what a landlord legally needs. A service includes that and adds stripping and cleaning the appliance, which is what keeps it efficient and keeps most manufacturer warranties valid. Different jobs, often done in one visit.

Yes. Cooker and hob connections, gas fire servicing and safety checks are all gas work under the same registration.

All of them. City centre, Broomhill, Crookes, Hillsborough, Ecclesall, Nether Edge, Woodseats, Dore, Totley, Handsworth, Darnall, Chapeltown, Stannington, Mosborough and everywhere between.
