Greenstar Highflow CDi series

RBHM were absolutely fantastic. There was no hard sell, just great customer service support. After a few conversations with Matt via whatsapp we were all sorted. The boiler was ordered and Malcolm turned up 1st thing the following day to fit. Amazing service and standard of work throughout and at a better price than everyone else. Thanks so much.

Couldnt fault anything. From getting a quote all the way through to installation. Quote was quick and easy and given plenty of options to choose from. installation was quick and tidy. The guy cleaned up and wouldnt have known he had been.

RBHM was great to deal with from when I made an enquiry right through to the job being finished. Henry and George were a great team and worked hard and professionally. Everything was explained to us and they left our house clean and tidy. They were both a pleasure to have around. I feel that the price for all the work involved was very competitive: it was only 65% of the figure quoted by the company recommended by our neighbour.

Just had a new boiler and radiators installed by your engineer team, they did a great job especially Connor who is very nice and efficient . Decent price.

First class job From start to finish the survey and fitting of my new boiler was first class.

We utilized RBHM's services for a recent boiler installation and were thoroughly impressed with their exceptional performance. Despite receiving multiple quotes from various companies, we never experienced any pressure or bothersome follow-up calls. From the initial survey conducted by Colin to the subsequent installation by Nick, every aspect was handled with utmost professionalism. The work was executed with meticulous attention to cleanliness and tidiness, and the after-sales service has been exemplary thus far. Although we encountered a minor issue during the installation, it was promptly rectified the following day. After bank Holiday. We wholeheartedly endorse RBHM and would readily avail their services again in the future. We commend the team for their unwavering commitment to excellence and encourage them to maintain this exceptional standard. Raj.

Just had a new boiler installed by Henry. Lovely guy all went very well .We would highly recommend the team at RBHM for their professional service from quotation to completion. Thank you

RBHM replaced our boiler and connected a HIVE smart system to control it. Yes they came across a few installation problems but OMG they were first class in sorting it out. Coming out over the weekend to make sure we had heating and water. Our next project is to replace our upstairs radiators and yes we’ll be using RBHM. Thank you Matt and your team of engineers for an excellent job!

A thoroughly professional company, they found a gas boiler solution for us that others had failed to find. I highly recommend them. The installation was first rate, Henry and Will were friendly, efficient and did an excellent job. Well done guys, I would have no hesitation to use them again.

Lovely people. Excellent job at a good price. Thank you.

Good courteous company, efficient, reliable and great job with immediate boiler replacement.

Thanks Matt & co. Decent price. Excellent customer service. Thanks for response to balance system and replace 2 TRVs

RBHM Ltd was the best choice by far, buying my new boiler. From the first minute they were more than happy helping me to choose the boiler that would be best for my house. And when we faced a potential problem with the installation they went above and beyond to find the proper and most economical solution possible, unlike some other companies I had quotes from. Installation took place 3 days after the order, the installer Tom was very quick and efficient and left my house clean and tidy.I must not forget to mention that I got 0% finance and 10 years warranty which was very helpful on choosing the best quality boiler.

Henry and Connor did a brilliant job.They knew what they were doing and did it quite methodically.They were always on time and worked through what was contracted with the company.My heating system has been working well.Matt was the initial point of contact and he handled everything well.All was done quite professionally and sensibly.

Very pleased with my boiler installation. Impressive service by the 2 guys attending. Great company.

Very responsive, Matt replying to emails etc within the hour. Very efficient use of technology made ordering a new boiler very straight forward. Installation was done without any issues. Would definitely use RBHM again.

We had our boiler and immersion tank replaced. Our experience from enquiry to working out the best solution to installation and communication was very good. Curteous and decent engineers.

Excellent service.left premises very clean and tidy. They recommended a boiler to fit available space without having to mess up our kitchen. Would use again.

Excellent service and well done job

Excellent service from start to finish, all round great work, from my 1st call people over the phone to the installers 5 star.

Excellent service all round. The sales team were very helpful. Tom, the engineer who came to install the new boiler was a star. He kept the work area tidy, and explained every thing he was doing.

Very good service thank you

Excellent service from start to finish. Very competitive quotes and efficient installation.

Fantastic company. Easy to get a quote, even for me, (not being very computer savvy). Competitive price, was able to trade in old boiler for £400! We paid half upfront and the rest on interest free credit, so we were able to manage our finances better. We had an appointment the following week for new boiler. Engineer was friendly and professional. Left everything tidy. We will be using this company for servicing in the future. Would definitely recommend. Mr. Mrs G. Basingstoke.

Top company would recommend very professional staff and installers clean and tidy and polite

Great communication and payment options. Work carried out to an excellent std.

Rbhm Installed a new central heating system on my house in the UK. I currently live 5000 miles away, so the whole process could have been extremely stressful. It wasn't - they did exactly what they said they'd do, for the price they quoted, and also sorted some additional carpet refitting issues at the end. Communication was quick, by phone and WhatsApp. All in all a fantastic, straightforward experience - would recommend to anyone.

From the initial quote to fitting RBHM were great. Matt contacted us early on to discuss the options available and offer his advice. The main reason that we went with RBHM was the fact that they were recommended to us by Viessmann who supplied the boiler. We now have a very efficient boiler with a 12 year guarantee. Thank you

I asked for finance as this is a lot of money all at once on a pension. They didn’t send me the finance contract to fill in. I was cold and wanted heat so I paid the deposit and now they are taking the full amount from my credit card. The admin doesn’t tally up with the instillation experience. However Superb instillation service. Henry was a delight and very efficient and friendly. He cleaned up after fitting the boiler and took all the old parts away. The roofers were quick and efficient. The two boiler fitters arrived at 8:15am and were finished by 1:15pm now I have a lovely cosy house again. Would definitely recommend the company but check the admin.

This company provides an excellent installation and after sales service. I can confirm this as RBHM have installed new Which recommended boilers in my propertie.

Best firm I’ve used. Boiler broke over the Christmas period and after absurd quotes from several other companies I stumbled upon these lads. Service was fantastic, rapid, trustworthy and top quality. Went above and beyond to fit my boiler. Not to mention they left the house tidier than when they turned up!

We are very happy with our new Viessman boiler which was recently installed. Thank you John and Conor for your professionalism.

Whole process from initial contact to final installation was quick and easy. Sales, Survey and Installation teams were very knowledgeable and professional. The installation team in particular did a fantastic job of relocating the boiler position from the kitchen to the loft which involved a fair bit of problem solving to move both the heating and gas supply pipework. Thoroughly recommended

The two guys turned up at 8am as promised. They laid protective to keep the carpets clean. The boiler was installed by 4pm and all necessary checks were carried out to ensure it is working correctly. A very good day's work.

Easy to deal with, turned up on time, worked hard and left the place tidy. Overall a good experience.

Efficient and professional service.

RBHM have recently installed a new Viessman Vitodens 100-W domestic boiler for us. We also chose to replace the pump and room thermostat. So far, so good. Everything is working fine and efficiently. The Engineers were very good, competent and respected our property with dust sheets etc. Very Satisfied.

Very pleased with the boiler installation. Henry and Aaron were top class the job was completed on time, very nice guys left the place clean and tidy.

The pre sales service was excellent. Had a few issues with installation but all OK now. If installation went to plan it would have been 5 stars. Overall good and would recommend.

The guys from RBHM done a fantastic job on the installation of my Worcester Boiler and storage tank in the loft. Thank you 👍

We found ourselves needing to change our boiler in December. RBHM installed our new boiler a few days after we accepted the quote and completed the job in one day. We were impressed by their professionalism and service and the new boiler is working well.

Efficient installation of new boiler and radiator. The workmen were very tidy and polite. Altogether a very good experience.

Boiler I installed on agreed day with no issues. Would recommend

With thanks to RBHM for coming out so quickly to change our boiler when our one was packing up just before Christmas. I can can highly recommend them. Shane find a fantastic job.

Immediate answers. No faffing around. Great service and great fitter

Absolutely fantastic service, very neat and tidy workmen, friendly and efficient. Very happy with our new heating system. Highly recommend

Thanks to rbhm team Arrived 8 am and work complete by 4 30 with new viessman boiler up and running I did have to have issue with a three way valve but this was replaced on another visit the house is lovely and warm and with lots of hot water very pleased with new heating system and have recommended rbhm to colleague who is having installed 13 th December Cheers

Very professional service. Fast, efficient and value for money. Would high recommend. Our new boiler is a beast!

A very professional company. Got a lot of information about my options, the survey engineer came (x2) and the quote followed efficiently. The work was carried out by Henry and Tom and was completed in the time allocated. The work to replace the boiler, the hot water tank and radiators to convert to a mains pressured system were all done whilst keeping the areas clean and tidy. Highly recommend them. A couple of teething issues which I'm sure RBHM will resolve for me.

Great job, quality Viessmann hardware, very nice installer. Thanks a lot guys

Recently had a new boiler installed by RBHM and very impressed by the professionalism and level of service they provided. All the team were great but a big thank you to Ryan for all his hard work and Paul for his great aftersales service. I'd be happy to use RBHM again and wouldn't hesitate to recommend them based on my experience.

I contacted RBHM via their inquiry sheet on a Sunday and within minutes they responded. They had someone come around to me the next day and by that evening I had a quote. The work was booked in very quickly. When the Engineer turned up on the day of insulation, he was on time and very polite. He kept me informed of any problems, even though I was a work so he phone me and at one point we were even speaking via my daughter face time. They have supplied all the warranties, manuals etc. I was recommend to use them by a family member and would recommend them to anyone.

Great service and clear efficient installation

My old Worcestor combi 24i boiler (16 years old) was giving me problems with the vessel and heat exchanger. Contacted several Boiler repair companies as I thought its time to replace. I did get a much cheaper quote rom a well known online only business and decided to go with them intially. However they soon started messing me around with installation dates plus as I had a Soft Water System they failed to tell me that this would need to be bypassed which would negate the purpose of having the water softner. I contacted RBHM who promptly came out and gave a quote (Colin), who advised due to water softner to opt for a Viessman rather then a Worcestor (Viessman have steel heat exchangers vs a Worcester which has aluminium). Mathew from RBHM gave me a date and they stuck to it, if I had any questions they were quick to respond. The paperwork was seemless and come installation date Ryan was very professional, tidy. (If you ever get Ryan to fit your boiler he likes Heart 80's Radio and a cup of tea). It has been justover 3 weeks since I had my boiler replaced by RBHM and so far I am pleased with the quality of the boiler and installation.

Our boiler installation had some initial problems with the hot water but these were soon resolved by Paul after a couple of return visits, I was pleased to feel supported by the staff in the office when things weren't quite right. These guys won't let you down they keep returning until everything is working to your satisfaction. A special thanks to Paul and Phil in the office for the reassurance that our initial problems would be resolved, they are as good as their word. Thank you.

Had first class service for my boiler fitting. Would recommend RBHM every time.

Very competitively priced, professional and customer oriented service.

Great boiler installation. Explained how to use it and how to use the new thermostat system. Have nothing but confidence that it will work efficiently. He even tested our carbon monoxide alarms for us as the old boiler was installed incorrectly and could have been leaking toxic gases into the home. Will be using Rbhm for all our servicing and will be recommending to anyone who needs help with their boiler. So much more professional than British Gas 👏👏

Henry and crew installed all new pipework, radiators, a Viessmann boiler and unvented 300 litre cylinder. They were courteous, diligent and overcame technical difficulties and communicated effectively the whole way through the job. If you take their maintenance plan RBHM offer a 12 year warranty on Viessmann products. They used 22mm pipe for the heating so the flow to the radiators is great and the hot water pressure is superb too.

Just had my boiler updated to a combi boiler the 2 guys we had were on time both days friendly and very tidy. Done a great job of the install and kept me updated though the day how they were getting on Will deff be using to service my boiler ona years time. Best of all were alot cheaper then other quotes and the work done looks great thanks again

Our ancient central heating system had been playing up repeatedly. How lucky we were to find RBHM Ltd to resolve all issues! Henry and Luke arrived promptly to install a new boiler, controls and rectify all the faults in the old system. So happy to have found this very competent company. Cannot recommend them highly enough. No more stress - all sorted!! Thank you Luke and Henry for doing a superb job. 👍🏻👍🏻

The boiler installation was completed swiftly, the site was left in a tidy condition and the controls explained.

Arrived on time. Did a very good job. Cleaned up everything, Would highly recommend

I needed Boiler replacement and an Engineer was sent over for a quick assessment as per my availability and a very reasonable quote with multiple options was provided thereafter promptly. Really pleased with the communication and arranging the appointment for boiler replacement. Whole process was very transparent. On the day of appointment, a very professional engineer carried out the work and kept me informed on anything i needed to know and how each instrument was going to function. Also informed me about the after care along with their contact details, in i case i need them in future. Very pleased with the overall service and their professionalism in getting the job done. Thanks.

We had excellent service from RBHM. From the quote to installation everything was very efficient and excellent value. Ryan completed the installation and did a first class job. All in all very impressive.

What a great service. I had two highly skilled, hard working men to take out existing gas fired hot air heating system and replace with conventional boiler with radiators. This was during hot weather over 30degrees and goodness knows what temperature it was in the attic! Still they kept smiling and did the job in 4 days. Very tidy, cleaning up after themselves as they went along. All this and better price than two other quotes! I’m really pleased 😁

Friendly, fast and all round great experience

Very good company. Excellent workmanship from start to finish

Very competitive quote. Henry fitted a new boiler and pump. Aaron came the next day to power flush the central heating system. Brilliant service from both guys - they were prompt, professional and courteous throughout. They kept me informed and answered any questions I had. We will be taking up the extended warranty.

Fantastic engagement from quote to survey and then install. Very professional and great price. I can strongly recommend RBHM for a boiler replacement. Would definitely use them again.

RBHM and Ryan were great. Good price, punctual and professional. Every went smoothly.

Very good service. All completed as promised.

Henry has been such a delight! Boiler installation - done! We are thinking of buying one of the service plans

We recently had a new boiler, hot water tank, controls and valves fitted by RBHM. Whole process was worry free. Surveyors answered all our questions. Price was very excellent. Special mention to the fitters Malcom and John. They were both extremely helpful, professional and very tidy. Nothing was too much for them. All in all a very good experience.

Quick , professional and affordable. Thank you RBHM for the fantastic conversion installation. Each person I dealt with was polite , honest and knowledge. Many thanks again for job well done !

Excellent service from start to finish. My hot water system is complicated and also has difficult access issues but from the quotation inspection through to the installation these guys were knowledgeable and offered practical solutions. Highly recommend.

Excellent work and very courteous

We had two engineers to fit a new boiler last week. They were punctual, friendly and extremely professional. Worked to a high standard, and were very knowledgeable about the product. Would thoroughly recommend!

All completed on time and by very competent staff

Very efficient from surveyors initial inspection, quotation, and installation within a week. Thank you Richard, Shane and Ben for a great job.

Absolutely super service from Toby and Ryan of RBHM. A new boiler fitted and working with no fuss or mess. Excellent quality of work. thank you.🙂

Highly recommend, Ryan and Luke were professional, efficient, polite and knowledgeable. They carefully cleaned up and hoovered any mess before they left, that was much appreciated. We had a few quotes before replacing the boiler and RBHM gave us the best offer.

RBHM, designed an excellent solution to upgrade the Heating System & Hot Water Cylinder. Mark & John did the work carefully, paid attention to detail and ensured the system was properly balanced at the finish. Would recommend RBHM.

I highly recommend to get your boiler installation.The engineers wre very competent,professional and provide excellent srvice.There are no hidden extras , very fair prising etc
