What Does a Gas Engineer do?
As gas engineers, we provide essential services that ensure the safety, efficiency, and reliability of your heating and plumbing systems. Our expertise spans a variety of key areas, including boilers, pipes, taps, and hot water cylinders.
Boilers
Boilers are at the heart of any heating system, whether in domestic or commercial settings. We handle the installation, maintenance, and repair of both gas and oil boilers.
Regular servicing of boilers is crucial to maintain efficiency and prolong their lifespan. We check for leaks, inspect components, and ensure they are operating safely. Replacing worn parts and cleaning the system helps prevent breakdowns and costly repairs.
Additionally, for new installations, we advise on the most efficient and suitable boiler for your property, ensuring it meets your heating requirements. Our team is Gas Safe registered, which guarantees professional and safe service.
Pipes
Pipes form the circulatory system of your heating and plumbing infrastructure. We install and maintain a variety of pipework, ensuring seamless and leak-free operation.
Our services include the fitting of new pipes during building projects and the replacement of old, corroded pipes that could lead to inefficiencies or water damage. We work with materials suitable for both gas and water distribution.
Our team conducts pressure tests and integrity checks to confirm the reliability of the pipework. We also handle emergency repairs, ensuring minimal disruption and quick resolution of any issues.
Taps
Taps are critical for day-to-day usage in both kitchens and bathrooms. We provide comprehensive services for installation, repair, and maintenance of taps.
Whether it’s a simple fix for a dripping tap or the installation of new, modern fixtures, our plumbing services cover it all. We ensure that the taps are properly fitted to avoid leaks, which can lead to water wastage and higher utility bills.
Our range of services includes fitting mixer taps, thermostatic taps, and sensor-activated taps, catering to various preferences and needs. We also offer advice on the best tap solutions based on aesthetics, functionality, and budget.

Hot Water Cylinders
Hot water cylinders provide a steady supply of hot water to your property, crucial for both comfort and daily activities. We specialise in the installation, repair, and maintenance of these systems.
There are different types of hot water cylinders, such as vented and unvented. We help you choose the right type based on your home’s requirements and existing heating system. Our installation services are performed efficiently to ensure minimal downtime.
Regular maintenance of hot water cylinders is essential to prevent issues like scaling, corrosion, and inefficiency. By ensuring proper operation, we help you maintain consistent hot water supply and extend the lifespan of your cylinder.

FAQs
We recommend annual servicing for all gas appliances. This is not just best practice but also a legal requirement for landlords. Regular servicing helps maintain efficiency, ensure safety, and extend the lifespan of your appliances. It’s also typically required to maintain your manufacturer’s warranty.
Our comprehensive gas safety inspections include:
- Testing all gas appliances for safe operation
- Checking gas pressure and flow
- Inspecting ventilation
- Testing safety devices and controls
- Checking for gas leaks
- Verifying proper flue operation
- Testing for carbon monoxide
- Providing detailed safety certificates
We operate a 24/7 emergency service in Cardiff with typical response times of 1-2 hours for genuine emergencies. If you smell gas or suspect a leak, you should first call the National Gas Emergency Service on 0800 111 999, then contact us for urgent repairs once the immediate danger has been assessed.
All gas engineers must be Gas Safe registered by law. Our engineers carry Gas Safe ID cards which show their photo, registration number, and specific qualifications. You can verify any engineer’s registration on the Gas Safe Register website. All Book Your Boiler engineers are fully qualified and regularly undergo additional training.
Key signs include:
– Smell of gas
– Hissing sound near gas appliances
– Dead or dying plants near gas pipes
– Unusual condensation on windows
– Physical symptoms like dizziness or nausea
– Higher than normal gas bills
If you suspect a leak, open windows, avoid electrical switches, and call the National Gas Emergency Service immediately
Our gas safety certificates (CP12) start from £75 for residential properties. The exact cost depends on the number of appliances to be tested and property type. We offer competitive rates for landlords with multiple properties and can provide annual renewal services with reminder notifications.
Our Gas Safe registered engineers are qualified to install and maintain all domestic gas appliances including boilers, cookers, fires, and water heaters. We’re also certified for specific manufacturers and can ensure warranty compliance. However, we’ll always check that your chosen appliance is suitable for your property before installation.
We accept all major credit and debit cards, bank transfers, and cash payments. For larger jobs like installations, we can discuss payment plans. We always provide detailed quotes upfront and won’t proceed with any additional work without your approval.
