Having a mobile version may not be that important if most of your visitors are using a desktop or a tablet.
However, you just make it so difficult for anyone to check the course and to make a booking.
Look at this page:

What is the QCF? What are the recent changes to the HSE checks? How many trained people do I need? Is it a one off course or do they need refreshers? Do you train me at work for the same cost as the open course?
It's only when I scroll down I see some of the answers but I still don't know how to book the course. I could call you but it's late in the evening so I really want to fill in a booking form - but there isn't one.
And all the page I looked at have out of date course information on them. An event manager plugin would fix this problem for you - and let me see all up and coming training and allow me to book a place on the course.
A blog post on christmas safety is a bit out of date now.
There my be more suitable training for my place of work but I don't know what they are until I look at the drop down. I know you have the FA page but you don't lead me there (because of the dropdowns). If I do look at the FA page I'm still confused as the type of training I need.
On my phone the menu is a huge long list and the telephone number in the header no longer displays.
I'm sure the training you provide is top quality but unless I know exactly what I need the site doesn't guide me in the right direction - I have to do a lot or reading and guessing in order to find the right course - I don't know for example if I need fire warden or fire awareness training.
The site layout is very dated and the tiny light font on the grey background is very tiring to read. And why all the borders and boxes? They make the site look very dated (and gloomy).
Where are the testimonials? You have some stars but I have no idea what these mean or where they originate. I clicked on one and it said than you for my vote. I reloaded the page and it let me give you a one star vote again. So it's possible for someone to really mess this up for you.
What is the logo supposed to represent?
A modern responsive theme and reworked content and navigation will make a huge difference.
There is a load more, but that will do for now.
