Environmental Heating Systems Ltd is a registered gas installer based at Johnstown, Kilkenny, listed on the public RGI register.

RGI registration R2415. Verify this number free on the public register at rgi.ie before any gas work begins.

Kilkenny city and county has a compact gas installer market centred primarily around Kilkenny city, where the natural gas network provides good coverage. The wider county is predominantly rural with oil and LPG heating common across smaller towns and farming areas. Kilkenny city's historic building stock — including period terraces and older commercial premises — provides consistent demand for boiler replacement and gas appliance work.

Gas services
Boiler, Appliance & Pipework
Kilkenny city has solid natural gas network coverage, while the rural county including towns like Callan, Thomastown and Castlecomer relies mainly on oil and LPG.
As an RGI registered installer, Environmental Heating Systems Ltd is legally authorised to carry out all notifiable gas work in Co. Kilkenny. The following jobs require a registered installer under Irish law:
- Gas boiler installation and like-for-like boiler replacement
- Gas boiler servicing, annual maintenance and fault diagnosis
- Gas cooker, hob and range connection and disconnection
- Gas fire and gas water heater installation
- Gas pipework extension, modification and pressure testing
- New gas connections to the Gas Networks Ireland supply
- Gas appliance repair and safety checks
- LPG tank connection, regulation and appliance fitting
On completion of any notifiable gas work a registered installer must issue a Declaration of Conformance, the completion certificate. It is what you produce for insurance, a property sale or a mortgage drawdown, so ask for it on the day rather than accepting that it will follow.
Off the gas grid
LPG Work in Kilkenny
Environmental Heating Systems Ltd holds LPG certification alongside Natural Gas registration, which suits properties in Co. Kilkenny that are not connected to the national gas grid. LPG is the common alternative across rural townlands, farms and older housing stock outside the main towns.
LPG requires separate certification from standard natural gas registration. If you are on an LPG supply and need a boiler installation, appliance connection or tank fitting, confirm the installer holds LPG certification as well as RGI registration before booking. Natural gas vs LPG explained.

Due diligence
Hiring a Registered Gas Installer
Before any gas work begins, there are a few things worth confirming regardless of which installer you use.
Verify the registration number
On rgi.ie. It takes under two minutes and confirms the installer is currently registered, not simply registered at some point in the past.
Get a written quote
That breaks down labour, parts and VAT separately. Gas boiler installation in Co. Kilkenny typically runs €2,200 to €3,200 for a like-for-like combi replacement, and emergency call-outs €80 to €180 depending on the hour.
Confirm public liability insurance
And ask for the certificate before work begins.
Request the Declaration of Conformance
On completion. A registered installer is legally required to issue one for notifiable gas work.
If the job is an oil boiler rather than gas, note that oil sits outside the RGI scheme entirely, so ask about OFTEC oil-firing certification instead. More on what RGI registration covers.
Gas work carried out by an unregistered person is illegal in Ireland and voids most home insurance policies. If you smell gas, ring the Gas Networks Ireland emergency line on 1800 20 50 50 before calling anyone else.
