Zuno Opco Limited t/a BOXT

We are super happy with the service Boxt provided us with. We had a broken boiler, fairly new 3yo. We got a quote from some local small business that was trying to scam us. We then found BOXT and arranged an engineer to come down and have a look at our boiler. Bless the man who arrived, he fixed our boiler within 10min by draining the water and putting more pressure into the boiler. We only wish to deal with this company going forward. Also, the whole process or requesting a job to be done is so good. We were asked to upload multiple pictures to help the engineer with preparation for the visit. They also followed up with a call to have a better understanding of what the job may require. Super thoughtful. Also very pleasant admin people and the engineer too. 5 star!! :)

Our BOXT Heat Pump Experience – Honest Review As with most major home upgrades, it's wise to do your research and get multiple quotes. We explored options from national providers and so-called "top tier" installers. Prices varied wildly, and while some seemed polished on the surface, they lacked transparency or didn’t let you speak with the actual system designers. We had previously used BOXT for a gas boiler and were very satisfied, so when we received an email about their heat pump offering, we looked into it. From the beginning, the process was refreshingly simple. The online quote tool was quick and flexible—we tailored it to include full replacement of all radiators and the towel rail. This gave us peace of mind, knowing the whole system would be brand new and efficient, rather than relying on a mix of 10-, 20-, and 40-year-old components. The initial consultation was smooth and accommodating. The overall value was outstanding considering the level of kit included: a premium Vaillant heat pump, 250L Vaillant hot water cylinder, and Stelrad radiators. Compared to a well-known installer who quoted us nearly three times the price (after the BUS grant and VAT), it was a no-brainer. The spec appeared virtually identical. Our surveyor and installer, Paul (KTD Heating), was fantastic. He had years of plumbing and heat pump experience, and brought practical thinking to the table—not just numbers on a screen. He addressed layout challenges, confirmed the large cylinder would fit, and answered all our questions confidently. We felt reassured by his thoroughness. We also had the chance to speak to Andy, the Head of Renewables, who gave generous time and expert guidance on optimising the system. He supported our choice of an open-loop setup with no TRVs, and a max flow temp of 45°C (so far running at 28°C), which is ideal for efficiency. Paul was assigned to the install and worked with a second installer and electricians to see the job through. Installation Experience All the kit arrived early, despite difficult driveway access. The delivery driver came directly from their HQ, covering a 400-mile round trip to ensure nothing was delayed—another sign of real commitment. Paul and Wayne (our second installer) showed up moments later and got to work. They were prompt, professional, and deeply committed. Everything from the laser-straight pipework to the carefully sculpted copper runs (which were almost too beautiful to cover) reflected real pride in their work. Despite many curveballs—including retrofitting into old pipework and replacing 15 radiators—they remained calm, worked late when needed, and returned on time each day to finish the job. They were courteous, tidy, and trustworthy—we had no hesitation leaving them in the house. It’s worth noting they gave up their own time away from family to get everything done right. Performance and Final Thoughts Heat pumps absolutely work. Our home is now evenly heated to a consistent 21.5°C with no hot or cold spots, and the rads don’t even feel hot—just efficient. It’s actually quite a luxury compared to gas, which fluctuated and left some areas too warm and others too cool. Noise-wise, it’s no louder than a gas boiler firing up. On a warm day, it can even act like a mild outdoor AC unit when timed with your hot water cycle. Running costs at standard electricity rates are comparable to a modern gas boiler. Add in smart tariffs, solar, or a modest home battery, and it starts to pay back. On a sunny day, you can cover your heating, hot water, and general electricity with your own energy—cutting ties with gas entirely. Thanks to Paul and Wayne's skill, care, and experience, this complex retrofit was smooth, efficient, and stress-free. If you get the right person designing and installing your system, a heat pump is one of the best upgrades you can make. THANK YOU BOXT, Paul, Wayne and team!

Boiler was fitted fine and works fine but condensation pipe which they insisted in fitting broke some tiles and has leaked 3 times over 2 years and now they are saying its outside warranty and refuse to come back to fix it again unless I pay. Really unhappy with this yet another big company with poor customer care

Absolutely amazing. Id recommend this company 100%. New boiler and 10x radiators fitted in a day by 2 lovely guys and they managed to get an electrician out on the same day to change a plug socket. It was booked as a 2 day job but due to the extra guy being available it was done in just a day. All the old radiators and boiler was taken away. The areas that had the work was all cleaned up. I was shown how to use the boiler and assisted to connect the WiFi thermostat up. The quote I got was over £1000 cheaper than all my local engineers/plumbers were quoting and I got to pick the boiler is wanted. Cant complain 100% recommend this company...plus the customer service over the phone were amazing with all the questions I had prior to ordering. !!!!!

Air con experts Seamless from choosing, order, install and warranty. Sales team took ownership. App is brilliant as saves time on phone and the workmen were tidy, professional and thoughtful for a complex job. Excellent products. Thanks so much.

Alex Rolfe carried out my boiler Type A RCD installation and the service was excellent from start to finish. He was professional, friendly, and explained everything clearly before completing the work efficiently. The installation was done to a high standard and everything was left tidy afterwards. I would definitely recommend Alex and BOXT to anyone looking for reliable and professional service.

We are not very happy with the boiler…

We are not very happy with the boiler service we received this week as some damage was caused which resulted in a 2nd visit by engineer (to rectify a water leak from the boiler) which could not be repaired and consequently we had to call the manufacturer who came today and fitted new parts

Very good company excellent service and…knowledgeable engineers

Very good company excellent service and knowledgeable engineers

BOXT Shows The Way.

My combi boiler needed replacing. I tried to obtain quotes but only BOXT responded quickly and positively while other suppliers prevaricated requiring site visits etc. After submitting my photos BOXT kept me fully informed and I had a range of competitively priced boilers to choose from and my choice was installed the next day. The gas engineer Liam was very professional and left the working area spotless and gave instructions on how the system worked when he had finished.

easy to order everything went spot on

easy to order everything went perfectly, fitter arrived on time, courier on time, cameron the installer went through everything before started, heating system is now working perfectly, and house left clean and tidy, and all rubbish taken away
