Gas is safe in the hands of an expert but in unqualified hands the results can be disastrous. There is more than an 81 per cent chance that a significant gas safety defect will be left in gas work carried out by an unregistered installer. That's why by law all installation businesses carrying out gas work for you must be registered with CORGI. All engineers at Wallwork are CORGI registered.

Unregistered installers and DIYers are not only breaking the law but can also put yourself, your friends and your family at risk. Remember: No one checks their gas work to make sure it meets the required safety standards.

Be safe. Ensure your gas appliances are checked for safety annually. Don't try to save on safety. You may end up paying far more.
