Gas Safety System Manufacturer Guides
Most UK commercial kitchens run one of five interlock platforms. Knowing which panel you have speeds up diagnosis, parts supply and any upgrade decision.
- Parts and coils stocked for the common UK platforms
- Like-for-like panel swaps without repiping in most cases
- Recommissioning and certification with every repair
Platform overview
| Manufacturer | Typical models | Notes |
|---|---|---|
| Merlin / S&S Northern | CT1250, CT1650, CT1750 | Very common in UK kitchens; combined interlock and proving variants, clear lamp diagnostics |
| Medem | Easy-Gas, Kitchen Guard range | Modular interlock and detection; proving options |
| Flamefast | GIP / interlock and proving panels | Widely specified in schools and colleges |
| Intelligas | Interlock and proving controllers | Compact panels, common in refits |
| Duomo | Gas detection controllers and heads | Detection-led systems for plant rooms and cellars |
Merlin / S&S Northern CT series
- CT1250 — ventilation interlock with fan proving and e-stop inputs
- CT1650 — interlock with gas pressure proving sequence
- CT1750 — extended interlock with detection and BMS interfacing
- Common faults: coil failures, pressure switch drift, blown panel fuse after a canopy cable fault
Choosing repair or replacement
If lamps and relays test good and spares are available, repair. If the panel is obsolete, has no proving where proving is now required, or has suffered water or grease ingress, replacement with full recommissioning is the better value.

Frequently asked questions
Can you service any brand of interlock panel?
Yes — our engineers carry parts for the mainstream UK platforms and can recommission any make to its manufacturer sequence.
Can I mix brands of valve and panel?
Only where voltages, valve type and proving requirements match the panel specification. It must be verified at commissioning.
