Plumbing & Heating FAQs
Answers to the questions we hear most often about our non-emergency plumbing, heating and gas services.
What's the difference between emergency and non-emergency plumbing services?
Emergency services are for situations where water is causing active damage or you've lost essential services (heating, hot water) and need immediate help — we aim to reach you within 60 minutes, 24/7. Non-emergency services are for planned work like boiler installations, bathroom refits, tap replacements, gas safety certificates, and routine maintenance — these are booked at a mutually convenient time.
Both emergency and non-emergency services available across Bedfordshire, Hertfordshire, Buckinghamshire and North London.
Are your gas engineers Gas Safe registered?
Yes — every gas engineer we send is fully qualified and registered with Gas Safe, the official UK gas safety body. You can verify their registration online. By law, anyone working on gas appliances, boilers or gas pipework must be Gas Safe registered.
