How do I know if my gas system needs upgrading?
Signs include poor appliance performance, visible corrosion, low pressure, or if your current system doesn’t meet the needs of your home.
Can I upgrade just part of my system?

Do I need a new gas system when installing a new boiler or hob?
Not always, but we’ll assess your current setup and advise if an upgrade is necessary to support the new appliance safely.
