how much is a gas safety certificate?

How Much Is A Gas Safety Certificate?

If you’re a landlord in the UK, then you’d know a gas safety certificate is a legal requirement. If yes, then you’d probably like to know how much it’ll cost to get a gas safety certificate so you can make plans on obtaining one for your property. In this article, you’ll find all you need to know about the amount you’re expected to pay for a gas safety certificate in the UK.

First and foremost, let’s look into the use of the certificate. Basically, a gas safety certificate is the legal inspection of your property’s gas appliances which would be done on an annual basis. Only an approved Gas Safe engineer is allowed to carry out this statutory check. Ultimately, if you own rental properties in the country, this is a requirement you can’t afford to overlook to ensure the safety of your tenants.

Furthermore, included in this inspection are each and every gas appliances, chimneys, pipework as well as flues in the property. In recent times, several individuals make use of fewer gas appliances which ultimately implies that they may only need the servicing of their gas fire. Once you’ve passed the inspection, you’ll be given your CP12 certificate which must be kept for a minimum of two years. A copy should also be provided to your tenants within 28 days of issue. So how much will it cost to get a gas safety certificate?

Depending on your location in the UK as well as the number of gas appliances incorporated, the average cost of a gas certificate will range between £60 to £90. The Gas Safe engineer will carry out the task as a fixed and statutory job.

how long does it take to service an oil boiler?

How Long Does It Take To Service An Oil Boiler?

Are you about to service your oil boiler and wondering just how long it would take to completion? Well, you should first know that during an oil boiler service, there are a wide range of things that needs to be checked. As a result, the service can actually take some time and even more, depending on the present condition of your oil boiler.

During a boiler service, your qualified heating engineer will carry out the following tasks:

• Detach and clean both the burner and fan.

• Examine the combustion chamber rope seal.

• Wipe clean and descale baffles.

• Wipe clean and descale the main heat exchanger

• Detach, clean and replace turbulators

• Examine the combustion levels after cleaning.

He’ll also perform some tank and system checks which includes:

• Inspecting and cleaning condensate

• Testing the fire valve

• Cleaning or replacing the filter

• Cleaning the condense trap

• Conducting a thorough inspection of the tank and oil supply pipe to identify possible damages, deterioration as well as debris.

• Pressure testing the oil supply pipe at the point where it goes underground.

• Examining the system pressure.

With all the aforementioned activities and more, an oil boiler service may take relatively longer period of time when compared to it’s counterpart - gas boiler. This is mainly due to the fact that the boiler itself requires a thorough inspection as well as the oil tank where the fuel is being stored. You get your gas through the mains supply, however oil must firstly be stored inside the tank then filled up when it’s almost low. The oil tank will be inspected to identify possible leaks, bulging, corrosion as well as water.

So generally, an oil boiler service should take between the range of 1 to 2 hours to be completed.

Can I use a biomass boiler with other forms of heating?

Biomass boilers can be designed to work with other kinds of heating. The most common of these is solar thermal. This is a popular renewable energy pairing. Solar thermal heating will meet your hot water needs during the summer while a biomass boiler can operate as a backup during the winter when solar thermal panels do not perform as well.

How much does boiler cover cost?

To ensure your boiler is functioning efficiently and to keep your home warm, it’s important to see that your boiler is serviced on a regular basis by a licensed boiler engineer. Failure to do this can result in sudden boiler breakdown which can be a hard hitting blow to one’s financial power especially when there’s no boiler cover to cushion the blow or totally avoid it all together.

When your boiler is covered, it implies that you’re protected in the event whereby your boiler or it’s controls malfunctions or break. Several boiler cover will include the servicing cost, while some may not so it’s advisable to always go through the details, no matter how small, before entering into a boiler cover agreement. Typically, a boiler cover will cost between £60 to £100 per year and the payment is made on a monthly basis. Various boiler insurance companies have varying cover cost, however, here are the common boiler cover policies:

• Homeserve charges from £13 per month

• EDF Energy costs from £13.29 per month

• British Gas from £12 per month

• Scottish Power from £13.13 every month

• CETRI UK charges from £13.50 every month

• 24/7 home rescue costs from £9.60 every month

• Gorgi Home Plan costs from £6 per month plus 3 months free

• Your repair charges from £9.60 per month

• NPower Boiler Cover costs from £10.92 every month

• SSE Boiler Breakdown Cover charges from £4.95 every month

It’s important to note that sometimes you have the option of adding your boiler cover to your existing home insurance, if you do not want a standalone policy for your boiler cover. In many scenarios, this is referred to as an extra or add on service referred to as “Home Emergency Cover. When compared to the standalone boiler policies, this is usually a lot cheaper as it comes in around £5 per month.

how long does a gas boiler last?

When it comes to gas boilers, this is one of the most frequent questions that always pops up and for a good reason. When you invest a considerable amount of money to acquire and install a gas boiler in your business property, it’s only reasonable not only to expect the boiler to warm up your property efficiently, but also to do so for a long period of time. If you’ve just bought or about to get a new gas boiler, it’s likely you won’t have to worry about getting a replacement for a lengthy period of time. Several commercial gas boilers will last for anywhere between 10 to 15 years on the average. However in the event whereby you have an existing one that’s fast approaching the end of it’s useful life, then you should know the time go get a new gas boiler is just around the corner, and the earlier you make the purchase, the better (to avoid any surprise breakdowns that’ll leave your home super uncomfortable).

Just like any other home appliance, it’s a fact that an older gas boiler ( especially those that have been installed over a decade ago) are significantly less efficient that the new modern ones. When the older versions were manufactured is a completely different time to now as both technology and climate concerns are wide apart. So when your existing boiler is approaching the end of it’s useful life, it’ll be wise to start saving up to cover the cost of getting a new one. However, if it’s only about 5 years ago your boiler was installed, it’s highly likely to still be very efficient.

how much oil does a boiler use?

How Much Oil Does A Boiler Use?

Are you also interested in knowing the quantity of oil that a boiler consumes to heat up and keep a house warm? Well, you’ll find the answer here. There are so many influencing factors that determines the quantity of oil that’ll be used by a boiler. These factors include the number of hours they’re subjected to use on a daily basis, the boiler’s size as well as how efficient it is. Another factor is how you use your boiler, whether it’s only to provide heating or to provide both heating and hot water will as influence the quantity of oil your boiler uses. As a result, it’s almost impossible to provide an accurate estimate of the amount of oil that an appliance would require to keep running effectively.

In general, to provide a rough estimate, a mid sized oil boiler appliance could make use of up to 3.5 litres of oil per hour when full, but if it’s a large appliance, then it can burn up to 4 litres of oil per hour. However, it should be noted that this is only when the boiler is operating flat out. In the event whereby the water inside the heating system is already hot and the boiler is only working to maintain the level of warmth, much less quantity of oil will be used. And as expected, there will also be times in which your boiler will not be on, and therefore no oil or fuel will b used.

Your home’s size as well as how properly insulated it is can also be a significant influencing factor here. As you would have guess a big home and/or poorly insulated will use up more oil because it’ll be harder to heat up or keep warm. Overall, for some households, 1000 litres of oil will be sufficient to get them through the year, whereas the same quantity may not be enough to get other households through just the winter months.

how does the smart thermostat work?

If you’re building a connected home, a smart thermostat allows you to change the temperature in your home. And not only do several smart thermostats come with touch screens and a user friendly interface, but they’re also compatible with Amazon Alexa, Google Assistant and other voice controlled personal assistants. So how does a smart thermostat work? Let’s have a look!

Generally, smart thermostats are connected to the home’s Heating and/or Air Con system via C wire (common wire). Homes that lacks a C wire (especially older homes) will have to install one first before getting a smart thermostat. The C wire is a crucial element in the installation process as it works mainly to wire your smart thermostats into the Boiler system without tampering with the wiring for the other appliances in the house.

The smart thermostats comes with some special temperature setting which you can access by connecting them to your home’s WiFi. These include:

• Mobile Control

Most smart thermostats are specially designed to enable users to control the temperature of their home from the comfort of their couch or car via their unique mobile apps. This feature is just perfect if you particularly like getting the perfect temperature in your home without having to get out of bed.

• Humidity Controls

Although, the humidity of your home can not really be adjusted with a smart thermostat but you can always stay on top of it by monitoring it or setting an alarm on your phone to go off when the humidity changes.

• Geofencing Feature

With a smart thermostat, you can choose the particular times of the day you want it in action. This feature enables you to go on impromptu travels without having to worry about your energy bills - some smart thermostats come with the geotracking feature which determines when you’ve left the house and adjusts the temperature of the home accordingly with your energy usage in mind.
