Who We Are
About SMG Plumbing, Heating and Renewables
Our History
The story of SMG Plumbing, Heating and Renewables began over 25 years ago, when our founder first started working in plumbing. Four years later, at just 20, he took the step of going out on his own. That decision, made 23 years ago, is the foundation everything else has been built on. The core of the trade has always been part of what we do: general plumbing, boiler repairs and servicing, radiators, hot water cylinders and the everyday work that keeps homes running. Every job is a chance to earn trust, and the business has grown the way good trades businesses do, one dependable job at a time. As heating technology changed, so did we. Homes across Ireland have moved towards better insulation, lower running costs and renewable heat, and we built the skills to match, holding Level 7 qualifications in heat pumps and plumbing. Today, air-to-water heat pumps, underfloor heating and heat recovery ventilation sit at the heart of the business, alongside boiler replacements and RGI registered gas installations. The business has grown in size and scope too. What started as one young plumber working for himself is now a limited company with a team of five to ten people. We work for homeowners, self-builders, commercial clients and agricultural customers, and our work now includes large cold water booster storage tank installations for commercial and agricultural sites. Today we’re based in Tarmonbarry on the Roscommon–Longford border, serving Roscommon, Longford and the corridor towards Dublin, with larger projects taking us further afield. What hasn’t changed is the way we work. The principles that guided the business on day one still guide it now: be on time, be dependable, price fairly and get the job right first time. Twenty-three years on, that’s still how we do things.
Our Founder
Stephen McGuinness has spent 25 plus years in plumbing and heating, and for 23 of those he has run his own business. He went out on his own at just 20, with a clear idea of how the job should be done: turn up on time, charge a fair price and do it right the first time. “I went out on my own young because I knew how I wanted to work,” Stephen says. “If I tell someone I’ll be there at eight, I’m there at eight. That’s the bare minimum, not a favour.” Over the years, Stephen has built that approach into a limited company with a team of five to ten people, based in Tarmonbarry on the Roscommon–Longford border. As homes and heating changed, so did his skills. Stephen holds Level 7 qualifications in both heat pumps and plumbing, is an RGI registered gas installer, and today leads a business focused on whole-house heating: air-to-water heat pumps, boiler replacements, underfloor heating and heat recovery ventilation. Most of the calls Stephen takes are about heating: cold houses, unreliable boilers, and families planning new builds who want the system right from day one. “People want a warm house that doesn’t cost a fortune to run,” he says. “My job is to design a system that suits their home and the way they live in it, not just to sell them a box.” Stephen describes his own standards plainly: on time, dependable, customer-focused, fairly priced, and the job done right. It’s a philosophy that has shaped every part of the business. “I’d rather tell someone their boiler has a few good years left than sell them something they don’t need,” he says. “Do the job right and people call you back, and they tell their neighbours.” Whether he’s on site with the team or talking a customer through their options, Stephen’s approach hasn’t changed since the day he started: honest work, done properly, by people you can rely on.
Our Promise
Every customer who calls SMG Plumbing, Heating and Renewables gets the same commitment, whether it’s a radiator replacement or a full heat pump installation. These promises are simple, and they’re exactly what we’d want from any tradesperson working in our own home. We put them in writing because we intend to keep them.
We’ll Be There When We Say We Will
We work Monday to Friday, 7am to 6pm, and plan our days so we keep the times we agree. If anything changes, you’ll hear it from us first instead of waiting by the window. Your time matters as much as ours.
You’ll Get a Fair, Clear Price
We’ll explain what the job involves and what it costs before any work begins. You won’t be sold anything your home doesn’t need. If grant supports may apply, we’ll talk you through your options so you can plan with confidence.
We’ll Get It Right First Time
We design and install every system properly from the start, backed by our qualifications and 27 years of plumbing experience. We check our work before we hand it over. We’d rather take the extra hour on the day than leave you with a problem in January.
Why Families and Businesses Across Roscommon Choose SMG Plumbing, Heating and Renewables
For most families, heating is one of the biggest decisions they’ll make about their home. Get it right and the house is warm, the bills are manageable and you barely think about it. Get it wrong and you live with it every winter. That’s why families across Roscommon and Longford trust SMG Plumbing, Heating and Renewables with the job. We listen first. Before we recommend anything, we want to know how your home is used: who’s in during the day, which rooms are always cold, what you’re spending on oil or gas, and how you want the house to feel in January. Those answers shape the system we design. We give honest options. Not every home is ready for a heat pump, and not every boiler needs replacing. We’ll explain what makes sense for your house and budget, now and in the years ahead, and talk you through any grant supports that may apply. You decide with the full picture in front of you. We respect your home and your time. We work Monday to Friday, 7am to 6pm, and we turn up when we say we will. We work carefully in lived-in homes and keep you informed from the first visit to the final handover. We’re qualified for the job. RGI registered, Level 7 qualified in heat pumps and plumbing, and fully insured, with 27 years of plumbing experience behind us. Boiler replacement, underfloor heating in a new build or a full air-to-water heat pump installation, you’re in experienced hands. And we’re local. Based in Tarmonbarry, we’re part of the same community as the families we work for. Our reputation travels with every job we finish, and that keeps us doing things properly. When you want a warm, efficient home and a team you can rely on, SMG Plumbing, Heating and Renewables is the call to make.
Our Deep Knowledge of Roscommon Properties
SMG Plumbing, Heating and Renewables is based in Tarmonbarry, on the Shannon where Roscommon meets Longford. The homes and buildings around us are the ones we know best, and that local knowledge shapes every system we design. Housing across the two counties is a real mix. There are older farmhouses with thick stone walls, bungalows from the 1970s, ’80s and ’90s that have run on oil for decades, one-off rural homes extended over the years, and new builds designed to today’s energy standards. Each one heats differently. A system that suits a modern, airtight new build may struggle in a draughty older house, and a radiator layout that worked forty years ago may be wrong for a heat pump today. That’s why we start with the building, not the brochure. We look at insulation, room sizes and layout, existing pipework and radiators, and how the household actually uses the house. Then we recommend what makes sense, whether that’s a boiler replacement now, an upgrade in stages, or a full air-to-water heat pump with underfloor heating. Our climate matters too. Damp, mild weather and well-sealed modern homes make good ventilation essential, which is why heat recovery ventilation is a key part of what we offer for new builds and deep retrofits. It keeps fresh air moving and helps control condensation without throwing heat out the window. Rural properties bring challenges beyond heating. Farms, yards and commercial sites often need reliable water pressure and storage, and our large cold water booster storage tank installations are built for exactly that kind of demand. From Tarmonbarry to Longford town and across both counties, we understand the properties here because they’re the ones we work in.
Our Commitment to Excellence And Continuous Learning
Heating has changed enormously in recent years. Homes are better insulated, energy costs are higher, and air-to-water heat pumps, underfloor heating and heat recovery ventilation have moved from specialist extras to mainstream choices. SMG Plumbing, Heating and Renewables has kept pace with that change, because our customers deserve advice that’s current, not advice that was right twenty years ago. That commitment starts with qualifications. We hold Level 7 qualifications in both heat pumps and plumbing, giving us a formal grounding in how modern renewable systems are designed, installed and set up, alongside decades of hands-on experience. We are also RGI registered, so every gas installation and repair meets the standard the law requires. Excellence also means knowing the equipment. We work with heating systems from Mitsubishi, Daikin, Atlantic and Samsung, and we take the time to understand how each performs in real Irish homes. That lets us recommend the right unit for your property and set it up to run efficiently and reliably. A heat pump is only as good as its design. Getting the heat loss right, choosing the right emitters and setting the controls properly is the difference between a system that’s cheap to run and one that disappoints. We take that design stage seriously on every project, from a single boiler upgrade to a full new-build package. Continuous learning is also about honesty. We stay within the work we’re qualified to do. We don’t install air conditioning or air-to-air systems, and we’ll always tell you when a job sits outside our expertise. Twenty-five plus years in, we still approach every job the same way: understand the house, do the work properly, and leave a system we’re proud to put our name to.
Our Values: Honesty, Local Roots, and Reliability
At SMG Plumbing, Heating and Renewables, our values aren’t words on a wall. They’re how we’ve worked for more than two decades, on every boiler, every heat pump and every bathroom. Here’s what you can expect from us on every job.
Honesty
We tell you what your home actually needs, even when that’s less than you expected. If your boiler can be repaired, we’ll say so before anyone mentions a replacement. If a heat pump isn’t the right fit for your house yet, we’ll explain why and what would need to change first. We’re just as clear about what we don’t do: we’re not F-Gas certified, so we don’t install air conditioning or air-to-air systems, and we’ll never pretend otherwise. Straight advice, clear pricing and no surprises on the final bill. That’s how trust is built, one job at a time.
Local Roots
SMG Plumbing, Heating and Renewables is based in Tarmonbarry, on the Roscommon–Longford border, and the people we work for are our neighbours. We know the homes here: older farmhouses, oil-heated bungalows, extended family homes and new builds aiming for top energy ratings. That knowledge helps us recommend systems that suit the way houses in this area are built and lived in. Being local also means accountability. When your name is known in the community, every job counts. We serve Roscommon, Longford and the corridor towards Dublin, but home is where our standards are set.
Reliability
Turning up when you say you will sounds simple, yet it’s one of the most common frustrations people have with trades. We work Monday to Friday, 7am to 6pm, and plan our days so we keep the times we agree. If something changes, we’ll let you know rather than leave you waiting. Reliability also means systems that keep working. We design and install heating properly so you’re not ringing anyone in the middle of January. Dependable people and dependable heating: that’s the standard we hold ourselves to on every job
