Our testimonials

What our clients are saying

First time using CS Boxall. When I phoned, the office staff were so friendly and ready to help. They got me booked in quickly. When the engineer attend he was very polite and helpful and sorted the problem out. Would definitely recommend, a fabulous service.

Donna Thomas

Excellent company, I always have them for the annual boiler service which is very reasonable but more importantly they always assist with a problem. No hot water or heating last night, I left a voicemail and the engineer called at 8.15am and arrived at 10am, fault found and fixed. A big thanks to Alan for this and the office staff for sorting, would highly recommend CS Boxall

Heather J

I would just like to send a huge message of thanks to your engineer who sorted out our Rayburn boiler/timer problem last Tuesday. Please tell him it’s working perfectly now and convey our gratitude to him for his perseverance .

Thanks to your company too for its excellent standards of workmanship and professionalism. We have used you for a while now and have been very impressed with your high levels of service.

Sally Moran

Just wanted to thank you for the fantastic work that was done in our house. Both men were extremely polite and hardworking and did a brilliant job. We are also very grateful for you coming out much earlier in order for us to have heating again.

Excellent Service. Thank you so much.

Sarah Harper

I just want to pass on my thanks and appreciation for the work that you have recently provided help to get our boiler / heating back up and running in the hospice.

I'm sure that you're very busy but i really value how responsive you've been to help us.

We're really grateful to be working with you and I'm sure it's the start of a successful partnership.


I would like to say a huge thank you to the lady who took my call yesterday and managed to get someone to us in minutes. To say yesterday was stress would be an understatement. The plumber that arrived was so calm and collected and I just wanted to thank the company so much and apologise for my highly emotional state. No one ever expects to open their front door and be faced with that and especially so close to Christmas... on the day you are due to exchange on the house!

Thanks again and we will be recommending you to everyone!!!

Beca Griffiths

Can I please also pay a compliment to David for his outstanding work yesterday and thank you all for getting the heating working much sooner than I'd anticipated.

Jon Taylor

I wanted to say once again how helpful the two men were. They answered all my questions and were just very considerate.

I have been so pleased with your company and would highly recommend you.

Clare Hockings

I would like to thank you for the installation job last Thursday. Your men did a great job. Mine is not an easy property to work on or in and they were efficient and professional and very prompt in their timing of the work in spite of all.

They also did go above and beyond with details and did not treat me like a lamebrain civilian which made a change.
