Gas Safety Certificates

About our gas safety certificates service

Maintaining gas safety is a critical responsibility for any property owner. At Design N Build, we provide comprehensive gas safety certificates, often referred to as CP12 certificates, to ensure your gas appliances and pipework meet current UK safety standards. This service is essential for residential landlords who have a legal obligation to provide annual certification for their tenants, but it is equally vital for homeowners and commercial businesses. Our Gas Safe registered engineers conduct thorough assessments of boilers, hobs, and fires, checking for leaks, correct pressure, and proper ventilation. From small domestic flats to large scale Commercial Gas Services in industrial settings, we handle the technical inspections required to keep your building safe and compliant. We understand the administrative burden of property management, so we focus on providing clear, detailed documentation that satisfies both legal requirements and insurance conditions. Whether you are preparing for a new tenancy or simply want to ensure your family's safety, our team delivers reliable testing with minimal disruption to your daily routine.

What's included

• Landlord Gas Certificates

  Specialised checks for rental properties to ensure landlords meet their annual legal obligations under the Gas Safety (Installation and Use) Regulations.

• Commercial Safety Audits

  Comprehensive safety audits for business premises, including warehouses, offices, and commercial kitchens, often as part of wider Commercial Gas Services.

• Gas Boiler Safety Testing

  Detailed testing of domestic boilers to ensure correct combustion and safe exhaust of gases, preventing carbon monoxide risks.

• Gas Tightness Testing

  A full pressure test of the property's gas system to ensure there are no hidden leaks in the infrastructure.

• Ventilation & Flue Checks

  Checking that all gas-burning appliances have sufficient airflow and that flues are unobstructed and discharging safely to the outside.

Key benefits

• Enhanced Occupant Safety

  Our Gas Safe registered engineers ensure your appliances are operating safely, significantly reducing the risks of carbon monoxide poisoning or gas leaks in your property.

• Total Legal Compliance

  For landlords and business owners, a valid certificate is a legal requirement. We help you stay compliant with the Gas Safety (Installation and Use) Regulations 1998.

• System Longevity

  Regular inspections can identify minor defects before they become expensive failures, potentially extending the lifespan of your boilers, cookers, and heating systems.

• Improved Energy Efficiency

  A certified gas system operates more efficiently. Our checks ensure that gas is being burned correctly, which can help in managing and reducing monthly energy costs.

• Professional Validation

  Whether you are a homeowner or a commercial site manager, having a valid CP12 provides proof that your gas infrastructure is professionally maintained and safe for use.
