Boiler Servicing in Stevenage
Keep your boiler ready for the year ahead
A boiler can seem to be working normally while developing an issue that needs attention. TNG Services provides boiler servicing in Stevenage, with checks tailored to your appliance and its manufacturer’s instructions.

A closer look at your boiler
A boiler service is an opportunity to check how the appliance is operating and identify issues before they become more disruptive. The checks depend on the boiler model and the manufacturer’s instructions. They may include examination of the appliance and flue, relevant safety and performance checks, and inspection of accessible components.
Where further work is needed, we’ll explain the findings. A service does not automatically include repairing a fault or replacing parts, so you can make an informed decision about the next step.

Service visit or boiler repair?
Routine servicing and fault finding serve different purposes. If your boiler has stopped heating, is losing pressure or is showing an error code, mention it when you contact us. We can then discuss the visit that best fits the problem rather than treating it as a routine service booking.
For a routine service
Tell us the boiler’s make and model and, if you know it, the date of its last service. We’ll discuss a suitable appointment.
If something is wrong
Describe the symptoms or error code and when the issue started. Photos can help us understand what you’re seeing.
Boiler servicing questions
How often should I have my boiler serviced?
Annual servicing is commonly recommended. Check your boiler manufacturer’s instructions and any warranty conditions for the requirements that apply to your appliance.
Will a service fix an existing boiler fault?
Not necessarily. Tell us about a known fault when booking so we can discuss diagnosis or repair as well as servicing.
Is a boiler service the same as a landlord gas safety check?
No. These are separate services. If you need a landlord gas safety record, let us know when you enquire.
