Homeowner Gas Safety Certificates
Gas Safety Certificates for House Sales
When you are in the middle of selling your home, the last thing you need is a paperwork delay holding up the exchange of contracts. If your buyer’s solicitor has requested proof that your gas appliances are safe, or your property information forms are missing recent service records, you need a qualified engineer who can get the inspection done accurately and without fuss.
iWarm provides fast, fully accredited Homeowner Gas Safety Certificates across North East Lincolnshire. We supply the exact documentation you need to satisfy the conveyancers and give your buyer complete peace of mind.
Why Do I Need a Gas Certificate to Sell My House?
While a homeowner gas certificate isn’t a strict legal requirement in the same way a landlord’s certificate is, it has become standard practice in UK property sales.
During the conveyancing process, you will be asked to complete a Property Information Form (TA6). This document asks for the service history and safety records of your central heating system. If you cannot provide recent, valid paperwork, the buyer’s solicitor will almost certainly demand an up-to-date Gas Safety Certificate before allowing the sale to proceed.
Having this inspection sorted early prevents last-minute panics, avoids delays in the chain, and proves to the buyer that the home’s infrastructure has been well maintained.
What the Inspection Involves
Our Gas Safe registered engineers conduct a thorough, highly technical inspection of your domestic gas system to ensure it is completely safe for the new owners:
- Installation Tightness Testing: We pressure-test the entire gas pipework system to ensure there are zero leaks.
- Appliance Safety: We systematically inspect your boiler, gas hobs, and gas fires to ensure they are operating safely, burning efficiently, and are equipped with adequate ventilation.
- Flue Integrity: We verify that all exhaust flues are structurally secure and safely venting combustion gases outside the property.
- Digital Certification: Once the inspection is complete, we immediately issue a comprehensive Gas Safety Record that you can forward straight to your solicitor.
Are You a Landlord?
Please note: If you are renting out a property rather than selling your own home, you are legally required to hold a different classification of certificate. Please visit our dedicated Landlord Gas Safety Certificates (CP12) page for information on your mandatory annual compliance checks.

Frequently Asked Questions
Does a homeowner legally need an annual gas safety certificate?
There is no legal requirement for a homeowner to hold an annual gas certificate simply to live in the property. However, if you are selling your house, the buyer's solicitor will almost always demand a recent gas safety record. For general upkeep, we highly recommend booking an annual boiler service instead to maintain safety and efficiency.
Do you work with estate agents and conveyancers for property sales?
Yes, we regularly welcome enquiries from local estate agents, conveyancing solicitors, and home buyers. We understand that missing paperwork can hold up a property chain, so we provide fast, reliable homeowner gas safety checks to keep your sale moving.
I need a homeowner gas certificate urgently to sell my house. Can I book for tomorrow?
We know that property transactions are highly time-sensitive. We always aim to accommodate urgent requests for homeowner safety inspections. You can check our immediate availability through our online booking platform or call our engineers directly for rapid deployment.

For properties in North East Lincolnshire, our homeowner gas safety certificate prices start at £60 for 1 appliance, when the appointment is booked using our online platform. Extra appliances cost £15 per item.

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
