GAS LEAKS ARE LIFE-SAFETY EMERGENCIES — DO THE RIGHT THINGS FAST
Smelling gas in your property is the most serious household emergency. Natural gas is highly flammable and can ignite from any spark — a light switch, a doorbell, a phone screen. Even a small undetected leak can build up to dangerous concentration over hours. The right response in the first five minutes can prevent a tragedy.
Do these three things in order: (1) Don’t switch any electrical items on or off. (2) Open windows and leave the property if the smell is strong. (3) Call the National Gas Emergency line on 0800 111 999 first — they will isolate the supply at the meter if needed. Once the supply is isolated and the property is safe, call DCD to arrange leak location, repair and re-certification.

SIGNS OF A GAS LEAK
GAS SMELL
Distinctive 'rotten eggs' smell — added to natural gas specifically so leaks can be detected by smell.
HISSING SOUND
Hissing or whistling noise near a gas pipe, appliance, or meter — sign of escaping gas.
DEAD VEGETATION
Patches of dead grass or plants near the gas supply pipe entering the property — sign of underground gas leak.
HEADACHE OR DROWSINESS
Family members getting unexplained headaches, nausea or drowsiness at home — possible CO from incomplete combustion.
HIGH GAS BILL
Gas usage higher than normal for no obvious reason — possibly an undetected slow leak.
YELLOW FLAMES
Gas appliance flames that should be blue burning yellow or orange — sign of incomplete combustion.
DCD'S GAS LEAK DETECTION SERVICE
FULL GAS TIGHTNESS TEST
Comprehensive pressure test of the entire gas system in your property — meter to appliances. Identifies even very small leaks that would be undetectable by smell alone.
LOCATE AND REPAIR
Once a leak is identified, we pinpoint the exact location using electronic gas detectors and visual inspection. Repair using manufacturer-spec materials and full re-testing afterwards.
WHAT Redhill SAYS AFTER A GAS LEAK REPAIR
Ian J. — Redhill
Smelt gas in the kitchen on a Saturday evening. National Gas Emergency isolated the supply. DCD arrived within an hour — Gas Safe engineer, full property tightness test, found a worn cooker connector. Replaced it, re-tested, certified. Professional and calm throughout.
Julia K. — Redhill
Gas bills had been creeping up for months with no explanation. DCD tightness tested the system, found a tiny leak at a soldered joint inside an airing cupboard. Too small to smell, but enough to show on the meter. Repaired and re-certified. Bills back to normal.
Karen L. — Redhill
Hissing sound near the gas meter. DCD confirmed it was a leak at the meter union (just inside our side of the meter), repaired it with manufacturer-spec parts. Full pressure test before and after, written certificate. Excellent.
Linda M. — Redhill
Smell of gas in the loft area — couldn't locate the source ourselves. DCD used electronic detectors to pinpoint a leak at an old soldered joint that had failed with age. Replaced the joint, re-tested the system, certified. Peace of mind.

GAS LEAK DETECTION FAQS
WHAT DOES NATURAL GAS SMELL LIKE?
WHAT DO I DO IF I SMELL GAS RIGHT NOW?
HOW DO YOU FIND A GAS LEAK?
DO INSURANCE POLICIES COVER GAS LEAK REPAIRS?
CAN I HAVE A GAS LEAK WITHOUT SMELLING IT?
Yes — small leaks can be below the threshold of human smell. Signs of an undetectable leak: gas bills higher than expected, dead patches of vegetation near the gas supply pipe entering the property, persistent unexplained headaches at home (possible CO), or yellow flames on gas appliances. We recommend a periodic tightness test every few years for older properties even without symptoms.
