Gas Safety Certificates in Grimsby
Important Update:
Stricter Gas Safe Regulations Now in Effect
If you own or manage a property and you’re preparing to book your annual gas safety certificate in Grimsby, there is a major update to how all gas safety inspections will be handled going forward. The rules around tightness testing (the test used to check your gas service pipework for leaks) have changed.
What is Changing?
Previously, minor pressure drops during a test might have been acceptable depending on the system. That is no longer the case.
- Zero Tolerance for Pressure Loss: All gas service pipework must now show 0 mbar of pressure loss during a test. If there is any drop in pressure at all, the system will not pass.
- Universal Impact: This new standard applies to all gas installations upon inspection and will directly affect the issuance of Gas Safety Certificates.
- The Timeline: The new rule rolled out on 25th March 2026, kicking off a 6-month grace period. It becomes fully mandatory on 25th September 2026.
⚠️ Crucial Note for Landlords: Replacing gas pipes that are hidden inside walls, floors, or ceilings is a massive, disruptive, and costly job. Because the grace period is already underway, we strongly recommend auditing your properties and scheduling any necessary pipework upgrades well ahead of the September deadline.

As an independent, Grimsby-based Gas Safe engineer, iWarm delivers fast, fully certified gas safety checks directly to your door or rental property.
We cut out the call-centre delays, providing transparent pricing and direct communication from booking to certification.
Landlord Gas Safety Certificates
Securing an annual gas safety inspection for all tenant-used gas appliances and flues is a strict legal requirement. We provide official landlord gas safety checks specifically tailored for the Grimsby rental sector, keeping your portfolio compliant without the stress.

Homeowner Gas Safety Certificates
Missing or outdated gas safety documentation can instantly stall a property sale.

Frequently Asked Questions
Can I book a boiler service at the same time as my gas safety check?
Absolutely, and we highly recommend it. A gas safety certificate only verifies that the appliance is legally safe to operate and isn't leaking. A full boiler service includes those safety checks but goes further by stripping down the boiler, cleaning internal components, and optimizing efficiency to prevent winter breakdowns. Booking them together is also more cost-effective than arranging two separate call-outs.
What happens if my boiler fails the safety inspection?
If an appliance is found to be unsafe, we are obligated to safely isolate it from the gas supply and inform you immediately. Because you are dealing directly with an experienced diagnostic repair engineer—not just a basic inspector—we can normally diagnose the exact fault on the spot and provide a fixed-price quote to repair the appliance and issue your pass certificate.
Do you issue gas safety certificates in the villages surrounding Grimsby?
Yes. While Grimsby is our central hub, our service area covers the wider North East Lincolnshire region. We routinely carry out gas safety checks for properties in Waltham, Tetney, Healing, Humberston, Laceby, and surrounding areas.
How much does a CP12 Landlord Gas Safety certificate cost?
Currently our CP12 landlord gas safety certificate prices start at £55 for 1 appliance, when the appointment is booked using our online platform. Extra appliances cost £15 per item.
How quickly can iWarm carry out a landlord gas safety check in the Grimsby area?
We understand that tenancy deadlines or tight property sales mean you often need a fast turnaround. Because we are locally based right here in North East Lincolnshire, we can typically book and complete your Gas Safety inspection within 24 to 48 hours of your enquiry.

I had a boiler issue, stopped working. He arrived on the same day and ensured that the boiler works while we wait for parts. Kept me updated while parts were coming and asked if the boiler is still working. Always kept the area clean and explained what was the issue. Great job! Definitely recommend.Posted on Google

Fantastic service from Guy, who travelled out to Market Rasen on a Sunday when our boiler stopped working. He was super professional, quick to sort the issue, and great value for money. With kids in the house, getting the heating and hot water back on meant everything, definitely one of those luxuries you take for granted until they’re gone. Really appreciate the effort and would highly recommend.Posted on Google

Guy came to us today which was a wet and cold Sunday afternoon as my Elderly Mother was without heating. After initial contact a time was agreed and Guy arrived on the dot.... He was very good and explained everything he was doing ensuring we understood what was happening. Guy was very clean and there was not a single bit of mess left behind. He made sure we were happy with the work and didnt leave until he was 100% sure the problem was fixed. There was no hard sell with Guy at all he explained a few options for us in the future. Would HIGHLY reccommend Guy and have saved his details for future use. 5☆☆☆☆☆Posted on Google
