How much do Electrician services cost?

However, before you proceed, you’d probably wish to know exactly how much electricians charge so as to help you make a budget and start to plan. In this post, we’re going to give you a good insight into the cost of hiring an electrician to help you make informed decisions moving forward. Let’s take a look!

The price charged by electricians for a project is determined by number of factors. These factors include the electricians themselves, the location of your property as well as the electrical work in question. For instance, electrical jobs in older or period properties will be a lot more expensive than the ones in modern houses which features electrical wiring and fittings and comply with modern regulations (even more so if the wiring needs to be made up to standard). Furthermore, if you happen to reside on London and the South East, you can expect to incur more costs than the rest of the UK. The biggest cost driver, however, is the type of electrical job that involved.

In general, for an electrical inspection, you can expect to incur within the range of £120 to about £200, repair of an electric shower should cost about £80 to £140, installation of an electric hob would cost between £90 to £250, while replacing a ceiling light can cost within the range of £85 to £130. With these wide variety in prices, if you need an accurate estimate, it’s advisable to get in touch with a local electrician who’ll be able to pay a visit to your home or property and provide you with a reasonable quote for your unique electrical project.

The table shows the types of job that Electricians generally do and also the typical price series of these jobs. Some tasks take longer to finish than others so costs do vary by project.

Electrician FAQs

how many solar panels and batteries do i need?

How Many Solar Panels And Batteries Do I Need?

Are you presently considering adding a solar system to your home? With several homeowners in the UK using solar now, many more are realizing the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your home but do not know where to start, you’ve come to the right place.

Here, we’ll help you calculate the number of solar panels and batteries you’ll need to power your home. Starting from the panels, you can begin by taken into account everything that makes use of power in your home to get a good idea of how many you’ll need.

• Firstly, you’ll have to determine the number of watts you use. Simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• Secondly, you have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

Generally for a 1500 square foot house, you might need around 15 to 18 solar panels to cover the house’s electricity.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house. These factors include your home’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications. Once done, you’ll be able to calculate the number of batteries required by your home.

are electric radiators expensive to run?

Are Electric Radiators Expensive To Run?

Just like many home additions, the running costs of electric radiators varies largely on a number of factors. Great number of electric radiators typically comes with an in built thermostat which is designed to turn itself off automatically when not in use in order to save energy.

However the energy provider’s set electricity charge tariff will also have a great influence on an electric radiator’s running cost. Let’s take a look at the running costs of an electric radiator!

A 600 Watt electric radiator ( on a standard electricity tariff) will usually have a running cost ranging between 4 to 6 pence each hour. However you should also take note that this scenario might change in situations whereby the electric radiator is not calling for heat the full 60 minutes of each hour. And this is more likely to be the situation as the thermostat is programmed in such a way that enables it to turn itself off immediately there’s an achievement of your required room temperature level - usually within 10 minutes from the time it was switched on. As a result of this, the running cost per hour of electric radiators will be greatly reduced to just about 1 to 2 pence.

It’s also important to note that enhancing the insulation of your home can go a long way to add to the heat retention value of each room. Consequently, the duration at which the electric radiator calls more heating will be significantly reduced, which in turn, implies a lower electricity bill.

Another key factor that can play a huge role in saving on your heating bills is the programming as well as usage of your electric radiators. Every radiator comes with an independent digital thermostat with a number of 24/7 programming options to help achieve maximum efficiency. When the radiator is properly set according to your lifestyle, you can save as much as 50 percent on your heating bills.

How much do solar batteries cost?
How much solar batteries cost depends on the brand and type of battery and its capacity. At the moment, the cost is quite high because the technology is still new – but they will probably reduce, just like we saw the cost of solar panels reduce as the technology became more popular. It’s a great idea to get a solar battery installed with your solar panel system if you’re out most of the day. If you didn’t have a battery, all that electricity would simply go to the National Grid – but if you have a storage system, then while your solar panels are generating electricity in the day, it would get stored in the battery ready for you to use when you get home. Lithium-ion solar batteries are the most widely-used ones at the moment because they generally have a higher capacity and are more cost-effective. For a 3-4kWh battery, which would store enough electricity for a typical 4kW solar panel system, it will set you back an average of £3,400. If you need a larger battery, it could cost anywhere up to £6,000. Lead acid batteries are cheaper, and it can seem tempting to ask an installer to fit one for you – but they aren’t cheaper in the long run. While a 4kWh lead acid battery may only cost around £2,000, their life cycle is only around 1,800 cycles. A lithium-ion battery that costs around £4,000 would have a life cycle of about 4,000 cycles. That means that while the upfront cost is more, you won’t have to replace it as quickly as a lead acid one.
Which solar battery is the best?
With so many different solar batteries on the market these days, it can be difficult to know which solar battery is the best. Luckily, we’ve picked out some of the best solar batteries on the market so you can take a look at their stats and figure out which one is best for you. Powervault 3: 8 kWh model This lithium-polymer solar battery has a useable capacity of 8 kWh and a depth of discharge (Dod) of 100%. It’s covered by warranty for 10 years. Cost: From £7,020 Tesla Powerwall 2.0 The famous Tesla Powerwall has a huge useable capacity of 13.5 kWh and also has a 10-year warranty, with a guarantee that it will work at 70% capacity during those 10 years. It’s a lithium-ion battery. Cost: From £6,500 Powervault 3: 4 kWh version This more modest solar battery from Powervault has a capacity of 4 kWh, but benefits from the same warranty length and DoD as its 8 kWh brother. Cost: From £4,470 SolaX 3.3 This more affordable solar battery from SolaX has a 10-year warranty and a good DoD of 90%. Cost: From £4,010 LG Chem RESU 6.5 LG are an up-and-coming player in the solar market and their 6.5 kWh battery is one of the most affordable on the market. Its DoD is 90% and it comes with a 10-year warranty. Cost: From £3,043 To decide which solar battery is best for you, you need to consider:
  • The power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it
  • How often you think you will need to charge your battery
  • Your budget
  • Whether you care about having the latest technology and a recognisable brand name
When you’ve made these decisions, you can narrow down your choices. It’s also worth asking a few MCS-registered installers for their opinions on what they think would be best. Of course, they want to sell you whichever brand they supply, but they probably chose this for a reason. Ask them to give you a few pros and cons for the brands they recommend and see if this matches up with your research.
does my house need rewiring?

When it comes to electrical works, safety is always paramount. Although a complete house rewiring service may seem quite expensive, when compared to the safety it provides, you’d realize it’s well worth it. We know all too well that human nature tends to prevail to overlook small electrical issues until it’s too late or probably gets out of hands. When this happens, not only will you have to spend more to get the issue resolved, but it may also lead to some damages to your property. Hence, the need to identify and resolve electrical deficiencies as soon as possible. In this post, we’ve compiled a shortlist of some of the top signs that your house needs rewiring. Let’s take a look!

  • Dimming or flickering lights. This is one of the most common signs that your house needs to be rewired. When a light brightens, it means there’s too much voltage and when it dims, it implies it’s receiving too little voltage. You may be tempted to think this is a lighbulb issue, but this type of decline in power is usually as a result of a loose wiring or faulty circuits which should not be ignored.
  • Regularly blown fuses. With the steady development in technology as well as electrical appliances within our houses, older style fuses that are not designed to contain this amount of electricity will end up blowing. If your fuse blows on a more regular basis, then there may be a need to upgrade them to more modern circuit breakers.
  • Lightbulbs burning out in their sockets. This is usually a sign of bigger issues in your wiring which is often caused by fluctuations in voltage.
  • Sparking outlets. These can be perfectly normal, but at times they can also be a clear signal of a potentially dangerous problem which should not be ignored.
what size electric boiler do i need?

What Size Of Electric Boiler Do I Need?

If you’re thinking about installing central heating in your home or property, you’ll be shocked by the plethora of options that’s currently available in the market as regards the boiler type that can be installed. Being a very good alternative to gas boilers or an oil or LPG boiler, electric boilers are here to stay. They usually feature different power outputs which tends to lead to one of the most frequently asked questions about electric heaters - what size of electric boiler do I need? Here, we’ll give you a good insight into sizes of electric boilers available to help you make the right decision.

The importance of getting the perfect size of electric boiler for your home can not be over-emphasized. If your electric boiler size is too small, it won’t be able to provide the level of heat and hot water required. And on the other hand, if it’s too big, it’ll definitely consume more electricity which would be a total waste of money.

To determine the correct size, if you have a wet central heating or water radiators in your home, you’ll need to calculate the boiler’s capacity required to operate them and allow 1.5kw per radiator. To be more accurate, it’s advisable to talk to a professional installer to avoid making a costly mistake. Every professional installer should have an idea of the appropriate size of electric boiler that’ll be needed given your special requirements and home size.

Generally, with a 12k kilowatt boiler, you should be able to operate up to 7 to 8 radiators which is good for smaller properties. For apartments and flats, getting a smaller electric boiler would be the best option.

can you replace a gas boiler with an electric boiler?

Can You Replace A Gas Boiler With An Electric Boiler?

In the UK, there are about 22 million households that are heated with the use of a gas boiler. However, do not assume that they’re the best type of boiler to install. The fact is, if your house isn’t connected to the main gas supply, the best option is for you to install an electric boiler rather than a gas boiler. So is it possible to replace a gas boiler with an electric boiler? The simple answer is yes. Both heating system options work in varying ways and also with a different impact on the environment.

The gas boiler is able to generate heat with the help of a gas burner. A heat exchanger is linked to the burner and heats the water available in its chamber. The hot water is then supplied to the heating circuit.

However, the thing is that natural gas can actually be more affordable when compared to using electricity to operate your boiler, but they have a negative impact on the environment. This is because gas boilers make use of an odourless, colourless and poisonous gas - carbon monoxide.

Meanwhile electric boilers are powered by electrical energy, hence, no carbon monoxide leak risks. Instead of using gas to heat up water, electric boilers distribute energy to heating elements which, in turn, heats up the water. So thinking about what’s best for the environment, you’d go for electric boilers. However, they’re more costly and are not as efficient as oil boilers.

If you reside in a smaller house that’s not connected to the main gas supply, then you might want to consider installing an electric boiler. However, if you live in a larger house, an electric boiler may not be the best option as they’re mostly designed to generate little quantity of hot water.

How do I connect solar panels to a battery?

Most people want to connect solar panels to a battery when they’re not at home all day to use the electricity they generate, or generate more than they consume over a day. Solar batteries are a great way to maximise the savings on your energy bills since you can use every unit of electricity you generate.

If you want to connect your solar panels to a battery, the best – and safest – way is to ask an MCS-registered company to do it for you. They’ve had lots of training and hold qualifications in handling electricity and installing solar batteries, so they will be able to recommend the best battery for your solar panels and for the among of electricity you use. Some of the brands they might recommend include Tesla, SolarEdge and SolaX, but there are many more to choose from. If you want to send electricity to the grid from your battery to receive Smart Export Guarantee (SEG) payments, it’s also worth leaving installation up to a registered installer. This is because you might not be eligible for payments if your battery wasn’t installed by an MCS-registered company.

However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

But it’s worth remembering that electricity is extremely dangerous when handled improperly. If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.
