Our reviews speak for themselves
Matthew Burton
I have used B4BC for almost 6 years now with my existing business & when it came to setting up my broadband / phone provisions for a new business I went straight to B4BC. These guys have exceptional customer service & take all the stress off your plate so you can focus on the million other things you need to take care of within your business. Could not recommend any higher!
Krishna Pariyar
B4BC has been the best system that I have used so far. They have solutions for every business phone system. The app works on both the desktop and phone, which have made operations convenient. Their support is great with response time and requests. And it’s really easy to reach the Account Manager through email, website chat support, phone and support ticket.
Dan Hall
I would highly recommend anyone to use B4BC for their phone and broadband needs. We have recently moved over to a VoIP system and the whole service from start to finish has been excellent.
Esther Wakeman
Absolutely thrilled with my experience after dealing with Best 4 Business. Not only have they saved our business a significant amount of money, but it has been a breeze to do. Efficient and friendly team.
Darren Lashford
Use B4BC for all our telecoms and its a breath of fresh air compared to who we used before. Recently moved our energy management through them and I’m equally as impressed. I wouldn’t hesitate for a second to recommend them.
Sarah Lowe
Fortunately getting in touch with the team at Best 4 Business is very easy, there are no long call queues so you’re not left on hold for ages & you don’t have to go through lots of different options before being connected to an actual person. The issues I have experienced have been dealt with immediately.
Conor Alexander
We’ve been working with B4BC for many years and they’ve consistently been a pleasure to deal with. Most recently, they upgraded our broadband and phone system – everything was handled smoothly and went exactly as planned.
Philip Wright
Working with Best 4 Business on a Communication system plan that provided modern solutions has been an absolute pleasure. The information afforded, depth of knowledge and flexibility provided was perfect for our future business requirements.
Mark James Morsley
Changing my entire office phone system and broadband is no small task, in fact it’s quite daunting. However luckily or really thanks to Google I found Best4 Business. These guys at B2B are just brilliant! I now have a new VOIP phone system, massively quick broadband, great phones, ongoing support and I have saved nearly £200 a month. Happy owner!!
Stuart Turley
Excellent service and support from these guys. It makes a change to be able to actually talk to someone when you require help without jumping through hoops, I would highly recommend them.
Matthew McKenna
Fantastic service from Best 4 Business Communications. I found this company online on Tuesday and within 2 days they had an engineer on site! We had been unable to get BT in for four weeks now.
Piotr Silwinski
I wholeheartedly recommend B4BC as an internet solution provider. Their outstanding customer service, technical expertise, everyday support make them the ideal partner. Thank you, B4BC, for your unwavering support and for keeping me connected every day!
