How to Compare Your Event Generator Quotes

In this blog we take an in depth look at how to compare generator quotes, we outline what you need to ask suppliers about before you book and the red flags to look for to avoid being caught out by surprise costs. 

At Grizzly Bear Events we are upfront and honest with our pricing from the start and everything is included before you book. 

However, there are many different ways suppliers quote generators and it can be hard to know where to begin when comparing generator quotes. 

Some suppliers include all costs upfront (like us), some include a few extras and unfortunately, there are companies out there that make their prices look low by keeping some costs discrete until after you’ve booked with them…or worse – until after the event! 

Read more to learn what to look out for:

1. First Impressions

Grizzly Bear Events aim to reply and quote within 24 hours of your email. We actively want to get you booked in with us, to make sure nothing is stopping you being prepared. 

Things to consider:

  • How quickly did you receive the quote after enquiring? 
  • Did you have to wait a while or chase to receive one? 

The answers to the above questions are a good indication of the level of support you can expect once you have booked. If you’re chasing at quoting stage, how can you be sure you can rely on the company after you’ve paid them.

2. The Generator Specification

Our ‘Denyo Eventa’ range of generators are designed for events, they are ultra-silent and run for over 24 hours on one tank of fuel.

Check out our ‘user friendly’ specifications here. Alternatively, if you are techically minded, you can find our manufactuers details for the 20kva generators here, and 40kva (37kva) spec’s here. We also stock the well respected brand Stephill as some of our 36kva generators too. 

Things to consider: 

  • What specification is the generator you’re being quoted?
  • Are you generators designed for events? 

3. Noise Levels

The noise level your generator will make is a very important point to consider when you compare generator quotes. Lots of people get caught out when comparing ultra-silent event generators with construction site alternatives. 

Our generators have a noise of around 55dB(a) when you’re 7m away – equivalent to conversation. The image to the right will help you compare volumes. We aim to position the generator around 10m away from the marquee itself to reduce the background noise further. 

Cheaper quotes might be for generators that are usually rented out to builders/construction sites. These can have noise levels of over 80dB(a).

Things to ask your supplier:

  • Will it sound like a freight train is passing your event?
  • What dB(a) levels should you expect?

4. Fuel Costs

Grizzly Bear Events include 20 hours of fuel in the price. Is fuel included in your other quote?

Others may charge after the event depending on actual usage. Depending on generator load and running time the amount of fuel used will very. If fuel isn’t included the quote, you should expect to add between £120-250 plus VAT to the cost after the event.

Our generators are also very fuel efficient, with some of the lowest consumption rates on the market, meaning they have less of an impact on the environment. 

Things to ask your supplier:

  • Is fuel included in the quote?
  • If yes, how many hours worth is included?
  • If no, what rate is fuel charged at? 

5. Cabling

Not every supplier inclides cabling to all required areas, or the installation. Some suppliers charge extra per plug socket. 

Grizzly Bear Events contact you a few weeks beforehand to make sure we bring the correct cable lengths and number of plug sockets required.

Cable is definitely something worth looking at when you compare generator quotes. We have heard, and seen first hand, generator arriving at venues without any cable to connect equipment up with.

Things to ask your supplier:

  • Is cabling included in the quote?
  • If yes, what length of cabling, are there restrictions? 
  • If no, how much extra will it cost? 
  • Is the cabling installed?
  • Are plug sockets included or are these all extra too?  

Examples of where you’ll require cabling for at an outdoor wedding or party:

6. Insurance:

Grizzly Bear Events do not want you to be worrying about anything going missing. With this in mind we insure all of our equipment, wherever your event is located.

Not everyone allows for this in the initial price. It’s worth checking – after all another £70-180 on costs is another case of wine!

7. Overall price including VAT:

Although we are a relatively small family run business, we have grown to the size we have to charge VAT on all of our rentals. 

Do not ignore the addition of VAT. Some companies may try to hire or ‘ignore’ this figure until you receive your invoice. VAT is currently 20% on outdoor event equipment rentals. Examples of not adding on the VAT:

Comparison example:
Grizzly Bear Events list price is £545 (20kva) – we make it clear this will be subject to 20% VAT – therefore £654 total.
Company A
 quotes you £575 but only mentions the VAT when it comes to booking (and that’s without the possible other extra costs)

Grizzly Bear Events is a total cost is £654.
Company A‘s quote is a total cost of £690.

You would save £36 by choosing Grizzly Bear Events in this example.
