Your boiler has stopped working. The heating won’t fire up. Or you’ve just received a letter from your letting agent asking for a CP12 gas safety certificate and you need one fast. Whatever the reason, you need a gas engineer who turns up on time, knows what they’re doing, and won’t charge you a fortune for the privilege.
Pluto Plumbers provides fully qualified, Gas Safe registered gas engineers for homes and rental properties across Hertfordshire and the surrounding areas. From emergency boiler repairs to annual servicing and landlord gas safety checks, we handle all domestic gas work with no hidden costs and no call out fees.
This page explains what a gas engineer does, why Gas Safe registration matters, what to expect on costs, and how to make sure you’re hiring someone who is properly qualified.
A gas engineer is a trained professional who works on gas appliances, pipework and heating systems. Every gas engineer in the UK must be registered on the Gas Safe Register before they can legally carry out any work on gas. That applies to everything from fitting a gas cooker to installing a brand new boiler.
A faulty boiler is the most common reason people call a gas engineer. Symptoms include no hot water, no heating, the boiler locking out with an error code, strange noises, or water leaking from the unit. Our engineers diagnose the fault, explain what’s wrong in plain English, and carry out the repair. We complete most boiler repairs in a single visit. For recurring faults caused by sludge and restricted flow, a power flush is often the correct fix.
If your boiler is beyond repair or more than 15 years old, replacing it with a modern condensing unit can cut your gas bills significantly. Our boiler engineers install all major brands including Worcester Bosch, Vaillant, Ideal and Baxi. Every installation includes a full system assessment, correct sizing calculations, and warranty registration on your behalf.
Landlords in England are legally required to arrange an annual gas safety check on every gas appliance in their rental properties. A qualified gas safe engineer inspects each appliance, checks for leaks, tests ventilation and flue integrity, and issues a CP12 gas safety certificate if everything passes. Pluto Plumbers provides landlord gas safety checks with certificates issued on the same day.
The Gas Safe Register replaced the old CORGI scheme in 2009. The Health and Safety Executive oversees it, and by law, anyone carrying out gas work in the UK must be on the register. It is the only official list of engineers who are qualified to work safely and legally on gas appliances.
This is not a box ticking exercise. Poorly installed or badly maintained gas appliances kill people. According to the Health and Safety Executive, around 7 people die every year from carbon monoxide poisoning caused by gas appliances that have not been properly installed or maintained. Research published by the Gas Safe Register found that roughly 5.5 million UK homes have at least one unsafe gas appliance. The UK Health Security Agency reports that around 20 people die each year in England and Wales from unintentional carbon monoxide poisoning, with 68% of those deaths occurring in autumn and winter.
Every Pluto Plumbers engineer carries a Gas Safe ID card. You can check the card number on the Gas Safe Register website at any time. Our registration number is 233221.
Some gas problems can wait until the morning. Others cannot. Knowing the difference could keep your household safe.
If you can smell gas, hear gas hissing from a pipe or appliance, or notice a pilot light that keeps going out, treat it as an emergency. Black marks or soot around a gas appliance, yellow or orange flames instead of blue, and increased condensation on windows can all point to incomplete combustion and possible carbon monoxide production.
Open windows and doors immediately. Do not touch any electrical switches, light matches, or use your phone inside the property. Get everyone out of the house, including pets. Once you are safely outside, call the National Gas Emergency line on 0800 111 999. This is a free 24 hour service run by National Grid.
Once the gas supply has been isolated and the property is safe, call Pluto Plumbers. Our emergency gas engineer will locate the fault, carry out the repair, and get your gas supply restored as quickly as possible.
Costs vary depending on the type of work. A straightforward boiler service costs less than a full installation, and an emergency call out on a weekend will usually cost more than a scheduled weekday appointment.
At Pluto Plumbers, we don’t charge call out fees. You’ll get a clear price before any work starts, with no hidden extras added to the bill afterwards. You can view our standard rates on our website for a full breakdown of what we charge.
For larger jobs like boiler replacements, we provide a fixed price quote after assessing the job in person. The price you agree to is the price you pay. No surprises.
A plumber handles water supply, drainage, taps, toilets, showers and general pipework. A gas engineer is specifically qualified and registered to work on gas appliances and gas supply pipework. Some tradespeople hold both qualifications, but not every plumber is a gas engineer.
If the job involves a gas appliance, a gas connection, or anything that touches the gas supply, you need someone who is on the Gas Safe Register. A general plumber without gas qualifications cannot legally work on these systems.
Pluto Plumbers employs engineers who hold both plumbing and gas qualifications. That means you get a single team that can handle the full scope of domestic work without needing to book separate trades.
Ask to see their Gas Safe ID card. Every registered engineer carries one. The card shows their name, photo, registration number, and the specific types of gas work they are qualified to perform. You can also verify any engineer’s registration online at gassaferegister.co.uk or by calling 0800 408 5500.
Once a year. An annual boiler service keeps your appliance running efficiently, catches small problems before they become expensive breakdowns, and is usually required to keep your manufacturer’s warranty valid. Research from the Institution of Gas Engineers and Managers found that 22% of UK homeowners have never had a gas safety check carried out on their home.
Yes, but only if they are on the Gas Safe Register. The certificate is officially called a CP12 and it confirms that every gas appliance in the property has been inspected and is safe to use. Landlords must arrange this every 12 months by law.
If the work involves anything connected to the gas supply, including boilers, gas hobs, gas fires, or gas pipework, you need a Gas Safe registered gas engineer. For water supply, drainage, taps, and systems that don’t involve gas, a plumber is fine. If you’re not sure, give us a call and we’ll tell you what’s needed.
Pluto Plumbers provides Gas Safe registered gas engineers for every type of domestic gas work. Whether you need a boiler repair, an annual service, a landlord CP12 certificate, or a same day gas engineer in a hurry, we’re here to help. No call out fees. No hidden costs. Just qualified engineers who get the job done properly. Call us on 079 5073 6082 or visit our contact page to book.
