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.
Can I check if my property has a gas safety certificate?
If you are unsure whether your property has a current gas safety certificate, you can contact us at CRS Matrix and we can help you verify this information. We will need to know the address of the property and the date of the last inspection. If there is no existing certificate or the current certificate has expired, we can arrange for a gas safety inspection to be carried out at your property. This will help ensure that your property is safe and compliant with gas safety regulations.
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.
What is a smart meter?
A smart meter is a digital energy meter that measures your electricity or gas usage in real-time and sends that information to your energy supplier automatically.
What is a CP12 or Gas Safety Certificate?
The CP12, commonly known as the Gas Safety Certificate, is a report that a Gas Safe registered engineer must complete annually. This certificate verifies that all gas appliances, pipes, and flues in your property are safe and meet legal standards. It is mandatory for all rental properties with gas installations.
Do I need an OLEV-approved installer to fit my home EV charger?
To qualify for government incentives like the Electric Vehicle Homecharge Scheme (EVHS), your EV charger must be installed by an OLEV-approved (Office for Zero Emission Vehicles) installer. These installers have met specific standards and are authorised to install EV charging points under UK government programs.
Is a Legionella Risk Assessment mandatory for landlords?
While not mandatory for all properties, landlords are obligated under the Health and Safety at Work Act to assess the risk of exposure to Legionella to ensure the safety of their tenants, particularly if the property has old pipes or a rarely used water system.
How long should a boiler service take?
A boiler service typically takes around an hour to complete, although this may vary depending on the type of boiler and the complexity of the service.
How do I find out when my boiler was last serviced?
Unless you have a written record of services from the previous homeowner, it can be difficult to determine when your boiler was last serviced. To play it safe, it’s best to schedule a service as soon as possible. After the service, make sure to keep track of the date to schedule your next service every12 months from then.
How do I find EV charging stations in the UK?
Apps like Zap-Map and PlugShare are great for locating charging stations across the UK, showing real-time availability and updates about new station installations.
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.
How quickly can I get a Gas Safety Certificate?
You will receive the certificate via email from our certified engineer when the inspection is finished. This is typically within 48 hours (longer if done on the weekend). Depending on the scheduling and availability, we can examine the same day. Please note, there might be a small charge if we have to expedite outside of our normal procedures. Contact us today to schedule an inspection.
How do I get a copy of my Gas Safety Certificate?
To obtain a copy of your Gas Safety Certificate, please contact us at CRS Matrix. Our team will be happy to assist you in retrieving a digital or physical copy of your certificate. Please provide us with your name and contact information, as well as the address where the gas appliance is installed. We may also need to verify your identity to ensure that we are releasing the certificate to the correct person. Once we have this information, we will work quickly to get you the documentation you need. Please note that there may be a small fee associated with providing a physical copy of your certificate.
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 much roof space do I need for solar panels?
The amount of roof space required depends on the size of the system you wish to install. Typically, a standard residential solar panel system needs about 15-20 square metres of roof space.
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.
What are the benefits of using an MCS-certified installer for solar panels?
Using an MCS-certified installer ensures that your solar panel system meets high standards of quality and compliance. It also qualifies you for various government grants and incentives, including the Smart Export Guarantee (SEG) that offers payments for surplus energy exported back to the grid.
How long does a Gas Safety Inspection take?
The length of a Gas Safety Inspection depends on the number of appliances being inspected and the complexity of the system. On average, it can take between 30 minutes to 2 hours.
