What we cover

Four areas of commercial gas work.

Each page has the technical detail, indicative pricing and FAQ.
Why operators and FM teams choose Blu-Red for commercial gas

One Gas Safe registered team. One log of work. One number to call.

Most commercial gas providers in London rotate engineers across customers. We don't. The same in-house team comes back to your site every year. They know the kit, they know the layout, they know the gas train. Your CP42 history stays in one place because the same engineers wrote every entry.

FAQs

Commercial gas: what people ask.

Is CP42 the same as CP12?

No, and the distinction matters legally. CP12 is the domestic landlord Gas Safety Record (Gas Safety (Installation and Use) Regulations 1998). CP42 is the commercial Gas Safety Record. Plenty of buyers (and even some commercial gas providers) confuse the two. We'll issue the correct form regardless of what was asked for. Free 30-second checker.

How long does a CP42 visit take?

Single appliance: 60-90 minutes. Standard restaurant or office kitchen with 3-6 appliances: 2-3 hours. Plant room or larger commercial site: half a day to a full day depending on access and complexity.

Do you do batched pricing for multi-site CP42?

Yes. 3 or more sites typically attract a 10-20% discount versus single-site pricing. We coordinate the schedule, send a single consolidated report, and invoice once.

What happens if you find a fault during the CP42?

Critical faults (gas leak, dangerous appliance, immediately dangerous installation) get isolated on the spot, a Gas Warning Notice is filed, and we discuss remediation immediately. Non-critical advisory items get listed on the CP42 with recommended timeframes.

How quickly can you book me in?

For routine CP42 work in London and the south east, usually within 1-2 weeks of enquiry. For urgent renewal deadlines, often within 48 hours.

Can I verify the Gas Safe registration?

Yes. Every CP42 we issue has Stewat Rogers's Gas Safe License (919290) and Registration (5608537) on it. Verify directly on the Gas Safe register.

Need a CP42 booked?

Single sites or multi-site portfolios. Gas Safe registered. From £150 + VAT. Multi-site batched pricing available.
