You may have gas appliances in your home – these must be installed, used and maintained correctly. Here's our top tips on household safety, what we are responsible for, and what you need to do.
Gas appliances such as boilers, cookers and gas fires are safe when they burn fuel correctly.
If your gas cooker has a crisp blue flame it means it is burning fuel efficiently and safely. Whereas a yellow or orange flame can indicate incomplete combustion and a carbon monoxide risk.
Warning signs of an unsafe appliance include:
Unsafe appliances can cause carbon monoxide poisoning, gas leaks, fires, or explosions. If you notice any of the signs above, act immediately and follow the emergency guidance below.
If you smell gas or suspect a leak, take the following actions straight away:
If the issue relates to any Watford Community Housing appliance, we will arrange for a Gas Safe registered engineer to visit.
If you are worried about a gas smell, appliance issue or ventilation problem, contact the National Gas Emergency Service on 0800 111 999. Please note down your reference number and provide it to us as this allows us to get a copy of your report.
Watford Community Housing has legal duties to keep you safe. We will:
These safety checks are a legal requirement and must be carried out every year.
You also play an important role in keeping your home safe. You must:
Failure to repair or replace any of your appliances marked 'At Risk' or 'Immediately Dangerous' could result in the appliance being disconnected at your next annual gas safety check.
Please note that portable flueless appliances are not permitted under your tenancy terms and conditions.
They state that you must not use or store any petrol, paraffin, liquid petroleum, calor gas heaters or other highly flammable materials.
The only exceptions include usual household goods (e.g. for lawnmowers, barbecues etc.) or items required for medical reasons, which you must notify us about in writing.
At least once every 12 months, a Gas Safe registered engineer will visit your home to inspect your gas system and landlord-owned appliances - this is called a Gas Safety Check (LGSR). This check ensures:
Please note that this check can be carried out up to two months before the due date without changing the original renewal date. This flexibility allows us to align checks for multiple appliances or properties, making the process smoother and reducing the need for multiple appointments.
You will receive a copy of the LGSR certificate once the check is completed.
If you own gas appliances (such as a cooker or gas fire), we strongly recommend you arrange an annual service. Regular servicing helps prevent carbon monoxide leaks, dangerous combustion, potential breakdowns during cold weather and blocked or unsafe flues. If a resident-owned appliance remains unsafe, we may disconnect it at your next service appointment to keep your household safe.
If you want to change your existing gas supply, or install a new gas appliance (including flueless appliances), you must request this through our formal application for alterations process.
This is essential in order to ensure compliance with safety regulations and maintain the integrity of the gas system. Unauthorised alterations or connections pose serious safety risks and may result in removal if not approved first.
Carbon monoxide (CO) is a deadly gas that you cannot see, smell or taste. It can build up without warning.
Symptoms of carbon monoxide poisoning include persistent headaches, dizziness or weakness, nausea or vomiting, shortness of breath, confusion or tiredness, chest or muscle pain, collapsing or falling unconscious.
Symptoms often worsen indoors and improve when you go outside. If multiple people or pets are affected, treat this as a CO emergency.
Your carbon monoxide alarm is one of the most important safety devices in your home.
You should:

To reduce winter breakdowns and stay warm:
Is your thermostat or heating programmer set correctly?
Is your boiler pressure within the recommended range?
Have you tried pressing the reset button once?
Are radiator valves open and radiators bled?
Do you have credit on your gas meter (for prepayment customers)?
Are vents and air bricks clear and unobstructed?
Have you checked the CO alarm battery?
If these checks do not resolve the issue, contact us for support.
Chimneys and flues in older homes may contain asbestos materials.
You should request a management asbestos survey before any inspection, cleaning, or servicing of chimneys in buildings built before 2000, and especially before 1980.
For any significant chimney renovation, removal, or appliance install, you must get a refurbishment/demolition asbestos survey first.
If you do not have a copy of the asbestos survey for your home, please contact us before any work begins so we can provide this information.
