All of it is legally restricted to Gas Safe registered engineers because a mistake in gas pipework does not announce itself the way a plumbing leak does; it can sit undetected until it becomes dangerous. ### Who it is for Homeowners renovating a kitchen and adding or moving a gas hob, anyone extending a property who needs the gas supply run to a new room, landlords with meter or supply issues affecting a rental property, and anyone at all who can smell gas, however faint, and needs it investigated immediately rather than waiting for a routine appointment. ### When you need it Planned work such as pipework extensions and appliance connections should be booked ahead of any kitchen fitting or renovation schedule, ideally before units and worktops go in, so the gas run can be positioned correctly rather than worked around afterwards. A smell of gas, a hissing sound near a meter or appliance, or a gas appliance that will not stay lit needs attention immediately, not at the next convenient slot. ### Why it needs a registered engineer Gas installation and repair work is notifiable and controlled by law precisely because the failure modes are serious: fire, explosion and carbon monoxide poisoning. Pipework has to be sized correctly for the total demand of every appliance it feeds, sealed and tested to hold pressure, and routed to comply with ventilation and proximity rules. None of that is visible once plaster or flooring goes back over it, which is exactly why it has to be right first time.

Our process ## How We Carry Out the Work, Step by Step - 1 ### Step 1: Assessment or emergency response For planned work we survey the property and discuss what you need connected or altered. For a reported gas smell or suspected leak, we treat it as urgent and talk you through immediate safety steps over the phone while arranging to attend. - 2 ### Step 2: Leak detection and tracing Using gas detection equipment and pressure testing, we trace the exact location of a leak along the pipe run rather than guessing at joints or fittings to replace speculatively. - 3 ### Step 3: Pipework design and sizing For new work or extensions, pipe diameter is calculated against the total gas demand of every appliance the run will feed, not just the new one being added, so nothing downstream is starved. - 4 ### Step 4: Installation and connection New pipework is run, appliances connected with the correct fittings and isolation, and everything sealed to current standards, whether that is a hob, a gas fire, an outdoor point or a full extension supply. - 5 ### Step 5: Tightness testing and certification The completed installation is tightness tested to confirm it holds pressure with no detectable leak anywhere along the run, and you receive the relevant safety documentation for the work carried out. What you get ## The Difference It Makes ### Registered engineers for notifiable work All gas pipework and appliance work is carried out by Gas Safe registered engineers, registration no. 576059, as the law requires. ### Leaks traced, not guessed at Proper detection and pressure testing find the actual location of a leak, rather than replacing fittings speculatively and hoping the smell goes away. ### Pipework sized for total demand New connections and extensions are calculated against everything the pipe run feeds, so existing appliances are not starved when a new one is added. ### Tightness tested on every job Completed pipework is pressure tested before being signed off, giving you documented proof the installation holds gas safely. ### Fixed written price before work starts You know the cost of the pipework or appliance connection before we begin, whether it is a small job or a full extension supply run. ### Available seven days a week for urgent issues A suspected leak or a smell of gas is treated as urgent, with the phone answered 8:30am to 5:30pm every day of the week. In detail ## General Gas Fitting Work in Detail Kitchen renovations are one of the most common reasons homeowners need a gas fitter beyond routine boiler work. Moving a hob to an island, adding a range cooker where an electric one used to sit, or repositioning the gas point during a full refit all mean altering existing pipework, which is notifiable work regardless of how minor it looks. The trap many homeowners fall into is letting a kitchen fitter mark out and even move gas pipework as part of the general refit, on the assumption it is 'just a pipe move'. It needs to be capped, run and reconnected by a Gas Safe registered engineer, and it needs to be tightness tested afterwards, not simply reconnected and assumed fine because gas flows out of the hob when you turn it on. A smell of gas has a specific, correct response, and it is worth homeowners knowing it before they need it rather than working it out under stress. Do not operate electrical switches, including light switches, do not use a naked flame, open windows and doors for ventilation, turn off the gas at the meter if it is safe and accessible to do so, and get everyone out of the property while help is arranged. Very often a reported gas smell traces back to something straightforward, a slightly loose appliance connection, a perished rubber hose on an older cooker, or a pilot light issue, but it always has to be treated as potentially serious until it is actually diagnosed, never assumed minor in advance. Meter and supply upgrades come up more often than people expect, particularly in older Merseyside properties where the original gas meter and incoming supply were sized for far fewer appliances than a modern household runs: a combi boiler, a gas hob, sometimes a gas fire too. Adding demand onto an undersized supply can mean appliances underperform even though each one is working correctly in isolation, because the total gas available cannot meet the combined demand at peak times. Where we identify this, the fix runs through the gas network's meter provider process rather than something we can simply swap on-site, and we will explain that route clearly rather than leave you thinking it is a fault with the appliance itself. Landlord duties around gas go further than most people realise. Every gas appliance provided to a tenant, not just the boiler, needs to be included in the annual gas safety inspection: hobs, gas fires, and any other fixed gas appliance in the property. Pipework condition is checked as part of that inspection too. If a landlord has appliances installed or altered by unregistered tradespeople at any point in a property's history, that history matters, because a fault introduced years earlier by unregistered work can still be present and still be the landlord's responsibility to identify and put right now. ### Residential and commercial properties We carry out gas fitting work in houses, flats, HMOs and small commercial kitchens across Merseyside.

Can any plumber or builder move gas pipework?No. Any work on gas pipework or appliances must be carried out by a Gas Safe registered engineer. It is a criminal offence for anyone else to carry out this work, and it typically invalidates insurance if something goes wrong. What is gas tightness testing?It is a pressure test carried out on gas pipework to confirm the whole installation holds pressure with no detectable leak at any joint or fitting along the run, and it is standard practice on new or altered pipework. Can you move my gas hob to a new position in the kitchen?Yes. We run and cap the pipework to the new position, connect the appliance, and tightness test the completed work, which should always happen before the new hob is used. Why has my gas pressure dropped since I added a new appliance?Adding demand onto an existing pipe run without recalculating total capacity can starve every appliance on that run. We check pipe sizing and, where needed, the meter and supply capacity, before recommending the fix. Do landlords need to include gas fires and hobs in the safety check?Yes. Every fixed gas appliance provided to a tenant needs to be checked as part of the annual landlord gas safety inspection, not just the boiler. How quickly can you attend a suspected gas leak?We treat reported gas smells and suspected leaks as urgent and prioritise attending as quickly as possible. Call us straight away rather than waiting for a scheduled slot. Which areas do your gas fitters cover?Liverpool, Knowsley, Halton and St Helens.
