Gas Safety Certificates & Landlord Services

Offering a wide array of emergency plumbing, heating and gas services in the London area

Ensure Your Rental Property Stays Fully Compliant

Landlord? You’re legally required to get a yearly gas safety check.

At Keystone London, we provide certified inspections with a fixed fee, instant certificates, and annual reminders.

Our qualified plumbers check all gas appliances and pipework for safety, leaks, and proper function—including boilers that may need servicing or replacement. Same-day emergency checks available.

Gas Safety Inspection: what's included?

  • Check for signs of wear, damage, or unsafe installation
  • Ensure appliances (e.g. boilers, hobs, fires) operate safely and efficiently
  • Confirm proper ventilation and safe removal of combustion gases
  • Verify correct operating pressure and appliance performance
  • Detect leaks in the gas pipework throughout the property
  • Test flame failure devices, thermostats, and other safety controls
  • Ensure adequate airflow to prevent carbon monoxide build-up
  • Log make, model, condition, and whether it passed or failed
  • Provided instantly onsite (if all appliances pass)
  • Recommend repairs, servicing, or replacement if needed

What our customers say

I have found working with Daniel extremely pleasant, as he is clearly very capable, has good judgment and works very efficiently. I would be very happy if all future plumbing jobs in the flat were to be carried out by him.
