If you have been thinking about buying a standby generator for your home, now could be as good a time as any to do it. There is a global rise in the use of electrical power, and this is only going to increase because of climate change and the fact that we are all having to turn over to electrically powered vehicles as petrol and diesel ones become, in the UK at least, outlawed.

This is very likely indeed to increase the number of power outages that we experience. OK, you might say, if the power goes down for a couple of hours, so what? But what if it goes down for a couple of weeks as it did in the northwest of Scotland at the beginning of the year? That’s a whole different ball game. Investing in a generator now is just plain common sense.

You can actually buy a new generator in the UK for as little as about £300, but it won’t provide very much power. On top of that you have to allow for installation which would take about 3 days and cost a ballpark figure of £1,000.

However, the average home would need a much larger generator than that. You can see that an oven uses 2,000 watts, a fridge 1,200, washing machine 1,200, and so on. And there are a few things that are not shown such as a water heater, which also uses a lot of energy.

In order to buy a new generator in the UK you need to calculate the amount of power that you need and then add about 25% in order to allow for any overload.

You also need a transfer switch in order to transfer from the mains to the generator. You can get a manual transfer switch quite cheaply. However, a manual transfer switch, rather obviously, means that you have to physically fire up the generator and then when it is running at full speed switch from the mains to the generator.

Far better is an automatic transfer switch because this, again rather obviously, will automatically fire up the generator when the power goes down and switch over when it is up and running. That means that you are only without power for a matter of seconds. 

When it comes to the electricity that we use today, things have changed quite a bit in just the last few months. What with the war in Ukraine and the cost of electricity going through the roof, more people are certainly considering their options.

It used to be that a generator for the home was merely used for those occasions when the power goes down. This was not all that likely to happen in our big cities, but today, who knows? Not only that, but we may be coming to the point where electricity is so expensive that it is actually cheaper to produce your own using a generator! Something nobody would have even considered only a year ago.

If you are seriously considering buying a home generator, you need to make certain that you have one that is big enough to produce the power that you need. You can either work this out yourself, or better still have a qualified electrician do the calculations for you because you need to be certain that you are covered and add a little on top as a safety precaution.

The bigger the generator you need, the more it will cost, but there is also some good news and that is that you can buy used generators in the UK. This is much the same as buying a second-hand car. It still works, but it may not look as “flash” as a brand new one. In fact, if you are considering the option to buy used generators in the UK, at Blades Power Generation we always have some in stock. This is because some firms who use generators expand their businesses, and so need a bigger generator and then they will trade in their old one with us.

You will also need a changeover switch to start the generator when the power goes down. You can buy a manual transfer switch, but an automatic transfer switch, although more expensive, is always the preferred option.

This is because an automatic transfer switch does what it says on the tin. When the power goes down, it will automatically fire up your generator and then transfer over to it. This means that you will only be without power for a matter of seconds.

If you have a manual transfer switch, you have to be on the premises and do it manually. If you happen to be on holiday and the power goes down for four or five days, you will come home to a freezer full of unfrozen food. Not ideal!
