What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.
