Does a plumber service your boiler?
Absolutely! Plumbers can be the heroes of your boiler’s story. They have the skills and know-how to give your boiler the TLC it needs during a service, ensuring it stays in tip-top shape. However, it is important to ensure that the plumber is Gas Safe registered, which is a legal requirement for anyone carrying out work on gas appliances in the UK. CRS Matrix, here in Leicester are fully Gas Safe registered.
All gas businesses and their engineers must be on the Gas Safe Register to carry out gas work legally.
Why is my boiler making strange noises?
Strange noises can be a sign of several issues, such as trapped air, a faulty pump, or a faulty valve. It’s best to call a professional to diagnose the issue.
How can I maximise the lifespan of my EV battery?
To maintain battery health, try to keep charging between 20% and 80% capacity and use timed charging to avoid keeping the battery at 100% for extended periods. Modern smart chargers can help manage this automatically.
What if my gas safety certificate has expired?
If your gas safety certificate has expired, you will need to schedule a gas safety inspection as soon as possible. Our team at CRS Matrix can assist you with this. We will send a Gas Servicing Engineer to your property to carry out a full inspection and provide you with a new certificate once your gas appliances have been deemed safe. It is important to note that continuing to use gas appliances without a valid gas safety certificate can be dangerous and potentially illegal. Contact us today to schedule an inspection.
How do I know if I can get a smart meter?
Energy suppliers are obligated to offer smart meters to their customers. You can check with your energy supplier or the relevant government agency to see if you are eligible.
Do I need a Gas Safety Certificate to sell my house?
When you sell your house, you are not required by law to get a gas safety certificate. However, if your boiler is gas, a gas safety certificate—which you should have obtained when your boiler was last serviced—is advised for your own safety.
Does rapid charging damage the battery?
Regular use of rapid charging can accelerate battery wear over time. It’s recommended to use rapid charging when necessary and rely more on slower charging methods.
What warranties come with solar panel installations?
Warranties for solar panels and their components can vary; panels usually come with a 25-year warranty against manufacturing defects and performance guarantees, while inverters typically have a 5-10 year warranty. Labour might be covered for shorter periods, so check with your installer.
What time of year should I service my boiler?
It is recommended to have your boiler serviced in the summer or early autumn months, before your energy requirements start increasing for winter. This reduces the chance of a boiler breakdown when your home needs heating the most.
Do you legally have to get your boiler serviced every year?
While there is no legal requirement to have your boiler serviced annually, it is recommended by most manufacturers and boiler engineers to ensure that your boiler is operating safely and efficiently.
How can using energy-efficient lighting help me be more eco-friendly and save money?
Using energy-efficient lighting, such as LED bulbs, can reduce the amount of energy needed to light your home and save you money on your energy bills. LED bulbs are more expensive upfront but last longer than traditional bulbs, which can save you money in the long run.
How can I ensure my solar panels are installed correctly?
Always use a qualified, MCS-certified installer and check their references and past work. Post-installation, the installer should provide you with a performance estimate and a thorough inspection to ensure everything is set up correctly.
Can any electrician install an EV charger, or do they need special approval?
Not all electricians can install EV chargers. They need to be certified by a recognized body such as the National Inspection Council for Electrical Installation Contracting (NICEIC) or have specific qualifications like the City & Guilds 2919. It’s crucial to choose an installer who has the necessary credentials and experience with EV charging systems.
What responsibilities do landlords have regarding fire safety in furnished properties?
For furnished properties, landlords must ensure that all furniture and furnishings comply with the Furniture and Furnishings (Fire Safety) Regulations 1988. These regulations set levels of fire resistance for domestic upholstered furniture and other products containing upholstery.
What should I do if my boiler stops working?
If your boiler stops working, check the pressure gauge and try to troubleshoot the issue using the techniques outlined in this guide. If you’re unsure what’s causing the problem, it’s best to call a professional.
Can I charge my electric vehicle overnight?
Charging an EV overnight is efficient with both Level 1 and Level 2 chargers, taking advantage of lower nighttime electricity rates in the UK.
Do I need to have the boiler serviced in my rental property?
While there is no legal requirement to service the boiler annually, it is highly recommended. Regular servicing helps ensure the boiler operates safely and efficiently, and it can also prevent costly repairs in the future. Moreover, an annual boiler service is often required to maintain the warranty on the boiler.
What is the difference between a Gas Safety Certificate and a Gas Service?
A Gas Safety Certificate verifies that gas appliances, fittings, and flues in a property are safe to use, while a Gas Service involves checking the appliances for faults, cleaning, and ensuring they are working efficiently.
Are smart meters safe?
Smart meters are designed and tested to meet strict safety standards. They use low-level radio waves to transmit data, which are well within the safety limits set by the relevant authorities.
