Assert Heating Services are a reputable Gas Safety Certificate provider. We have established an exceptional reputation for providing speedy, efficient gas safety checks at very competitive prices. From affordable heating services to plumbing services or Gas safety certificates, we have the expertise for you, regardless your needs.

We have been happy to supply gas safety certificates to London and the surrounding areas since 2003. Our team consists of experienced professionals, including gas safety registered engineers and we aim to always deliver high standard inspections that are detailed, precise and avoid any extra costs.

By law, under the Gas Safety (Installation and Use) Regulations 1998, Gas Safety certificates are issued every twelve months by Gas Safe registered engineers. All pipework, gas appliances and flues must be thoroughly checked and certified for safe use.

Remember to keep the gas safety records for two years

All tenants will receive a copy of the records within 28 days of the gas safety check.

All Gas Safety certificates include information about all gas appliances in your home. The Assert Heating Services engineers will perform regular checks in order to make sure appliances work correctly and to safe standards. During the inspections we will check if all safety mechanisms are functioning properly, if ventilation paths are clear for evacuation and if any dangerous gases exist (in this case, we will safely remove any trace of dangerous gas).

Some of the information contained in the Gas Records include:

  • The position and description of checked appliances
  • Name, registration number and signature of the Assert Heating Services engineer
  • Date
  • Property address and name of the landlord or owner
  • Confirmation of the gas check results

Assert Heating Services will never settle for anything less than an unbeatable customer experience, we are dedicated to bringing a quality service and our gas safe registered engineers will do no less. Not only does this give you complete peace of mind, but it also means you can enjoy your home with no worry or uncertainty of a lesser service.
