Overview

System inhibitor labels tell the next engineer what is protecting the heating water. After a power flush, a new boiler or a top-up, you write the inhibitor product, the quantity and the date on the label, so whoever services the system next does not have to guess.

Who uses system inhibitor labels

Gas engineers and plumbers fitting boilers, power-flushing specialists, and heating firms with service contracts. Landlords and housing teams like them because they show the system was treated.

Where to fix an inhibitor label

On the boiler casing beside the service label, on the pipework near the filling loop, or on the front of the airing cupboard. Wherever the next engineer will look before draining or topping up.

Inhibitor label sizes and materials

The smaller label sits neatly on a boiler side panel; the larger has space for a full record.

Option	What it means	Good for
76mm x 51mm	Compact	Boiler casings, pipe runs
96mm x 68mm	Larger, more lines	Cupboard doors, plant rooms
Matt paper	Indoor, easy to write on	Kitchens and airing cupboards
Waterproof polypropylene	Matt laminated, indoor and outdoor	Garages, outbuildings, external boilers
Gloss paper	Shiny, indoor	Printed details only

Write-on lines to include

Inhibitor product, quantity added, system volume if known, date, engineer and next check. Your company name and phone number go across the top.

Inhibitor label quantities

Choose anything from 48 to 10,000; the polypropylene range opens at 250. If you fit a boiler most days, a larger pack brings the price per label right down.
