Grants now available for cavity and loft insulation

aligolds ★★★★★ Excellent service all round. And my house does keep the heat for a lot longer. Thoroughly reccomended.Mark C. ★★★★★ We used Arrow for a spray foam insulation in our loft. It was an efficient process from start to finish. Andrew and Samantha were friendly and easy to deal with and the job was completed very satisfactorily.Bharat H. ★★★★★ Really happy with the service from Arrow insulation, we got our quote and a scheduled date but because of a cancellation the work was done just before Christmas. Both Dan and Frank were very efficient, explained exactly what they were going to do. So glad to have the beads insulationCowley regular C. ★★★★★ Andrew and the team at Arrow have been professional from start to finish. We had our existing foam insulation removed, which is a horrible job. The team were hard-working, efficient and, in spite of the inevitable mess, were diligent in clearing up. We also had a new cavity wall insulation refill. Again, the work was carried out to a high standard and the chaps were super. A few days after the work was completed, we realised the loft area was full of foam. Andrew responded immediately, and the team arrived two days later to sort it out. I couldn't ask for more and wouldn't hesitate in recommending Arrow.Danny C. ★★★★★ We have recently had the Thermabead Insulation installed in our bungalow. The bungalow was getting cold in the evening when the heating had gone off. We only had the install completed a few days ago but we have noticed a difference already and the house is staying warmer into the evening.The service was excellent, Andrew came and measured and dealt with install and the installers were very tidy and helpful.Thank you Arrow Insulation.Chris ★★★★★ I'd like to say Arrow Insulation were amazing. Today I had my cavity wall filled, Dan and Frank were very professional, arrived at the scheduled time, polite, clearly explained the process and set expectations. After the insulation everything was clean, clear and tidy. Dan walked around the property with me while we looked at the work carried out and answered any additional questions I had.Thank you so much for both the extraction and insulation teams doing their work to a very high standard. Waiting for it to be winter now to feel the benefits of the cavity wall insulation.I would highly recommend Arrow Insulation to everyone looking at cavity wall insulation. Thank you 🙂colin S. ★★★★★ The experience from start to finish was extremely professional. So, from making the initial enquiry, which lead to an on-site visit, within a few days, with the resultant quotation on the same day, added to clear and constructive advice, all of which enabled us to make a reasoned evaluation and decision. After confirming our order, the installation date was quickly arranged and confirmed. The all-important implementation was extremely efficient (the team arrived on time), the site was made ready and the work commenced without major hassle nor inconvenience. The work was completed and the site cleared. The quality of the work is good (as far as we know, as it's only been a week!), but we have sufficient trust and confidence in Andrew and his team, that they all respond if we have any support queries. Highly Recommended!aurora 7. ★★★★★ Arrow installed cavity wall insulation and loft insulation for us and were extremely professional. The work and customer service were excellent!Carlos M. ★★★★★ Knowledgeable and professional, Andrew took great care to fully investigate our problem and recommend only solutions which made practical and economic sense, and in no way concerned with making a sale, let alone selling us anything unnecessary or inappropriate.Shane J. ★★★★★ Professional and friendly from start to finish. I had delayed getting my cavity wall filled for years due to all the horror stories but after a lot of research of cavity wall fill materials, best suppliers etc decided to go with Arrow Insulation. Initial survey was arranged promptly, everything was explained to me on the day, shortly thereafter received quote with insultation survey results (including predicted heat loss improvements etc). Install was speedy and painless (Thanks Dan & Frank) ie all done in just over 2 hours and the guys cleaned up afterwards ensuring all holes where filled with matching mortar.Would heartily recommendDenise Spangler (. ★★★★★ Really happy with the service! Got one of our party walls insulated. Job was done very quickly with minimal disruption and no mess was left.Jezza ★★★★★ Great service from Dan and Frank for cavity wall insulation given the freezing conditions.Urban P. ★★★★★ Arrow insulation are very very good at what they do. They are nice to deal with, very resonably priced, knowledgable and the guys (Shaun and Dan) on site were aslo super nice and did more work than they were contracted to. (They fixed my roof as they had long ladders).We need more businesses as good as Arrow Insulation!Sally R. ★★★★★ Arrow Insulation added cavity wall insulation to our house last week. Great guys, really friendly and professional. Easy to deal with, good job done. Would recommend.David B. ★★★★★ Most impressed with everything from the initial contact response, quick quotation, very quick install date, arrived on time, excellent work process, cleaned up afterwards. Highly recommended.Nigel T. ★★★★★ Cavity Wall insulation. This is a big decision, with lots of horror stories out there, so I spent almost a year thinking and researching before deciding that EPS bonded beads were the only solution, I'd entertain putting into my cavity walls. I then had to find a company I could trust. There are lots of bad companies out there, with (in my opinion) only a few good ones "locally" that I considered. Arrow seemed to fit the bill with good reviews and prompt responses from Andrew to some of my concerns and awkward questions. Arrow certainly aren't cheap, but I wanted it done right, and Dan & Frank gave me confidence that they'd done a good job on the install. Cement fill to drill holes is a pretty good match and will probably fade in even more over time (already very hard to spot), and having measured temperatures for several weeks prior to install (inside and outside), I can say for sure that there is a real improvement - particularly the internal side of external walls, where the temperatures now match the improved room temperature (rather than one to two degrees C lower than room temperature before the install). I'm happy with my decision, and pleased with the outcome.Peter C ★★★★★ I agree with other reviewers, this is an excellent company to deal with, a friendly and professional service throughout.They installed bead insulation in an extension and did a really thorough job and answered all my questions.Being for an extension I think some of the companies I contacted thought the job was too small for them and they were really only interested in complete house insulation.Would recommend Arrow to anyone.Adrian H. ★★★★★ Arrow Insulation carried out a free survey using a cavity camera and found I already have good cavity insulation and no work is required. They explained clearly about the insulation I have and that it is common in houses built circa 1993. Very friendly and business like.Raymond T. ★★★★★ Arrow insulation fitted cavity wall insulation for us last week. The team who fitted the insulation were kind and answered any questions. They completed the installation quickly and to a high standard. The insulation made a huge difference straight away. Our home now heats up much quicker and holds the heat for most of the day. To make things even better, the price was extremely good too. I can't comment on the longevity of the insulation since it's only just been put in, but so far so good.Jo K. ★★★★★ The product is amazing. Has made such a difference to my home. Really good customer care and Andrew made sure we were happy and informed before going ahead.Sharon P. ★★★★★ Andrew gave me great advice on the phone about a property I am buying. He went the extra mile and looked at some photos on the survey and gave me an email report back on them. Thank you for such a great service.Tim W. ★★★★☆ Arrow insulation fitted cavity wall insulation very efficiently. Staff were very friendly. The were a few minor administrative problems prior to the installation, but that was all sorted promptly. I can confidently recommend Arrow insulation.Martin D. ★★★★★ Arrow Insulation was recommended to us as a company who could insulate our loft with spray foam between the roof rafters. Andrew came to look at the space, explaining the benefits of foam versus fibre and provided a very competitive quote. Once accepted, the installation team arrived within a week and were courteous and professional, installing the foam within a morning.We're already noticing the difference between the poorly insulated loft and having the foam. Heating costs dropped straight away and the whole house is warmer. Plus, we can now board the loft space straight onto the joists without needing to raise the floor height to accomodate fibre roll.David B. ★★★★★ Excellent response from Arrow with both survey and installation of Loft insulation very satisfactory. Many thanks!Miriam ★★★★★ Brilliant job completed on our cavity wall and loft insulation. Extremely pleased with the results - so polite and clean throughout the work. Would highly recommend Arrow.Cari C. ★★★★★ Great service from getting a quote, booking and the installation of cavity wall insulation from Dan and Frank, who made sure no leaks and ensured my tumble dryer outlet worked! Really great company to deal with. Less cost than bigger firms and better service. I’d recommend the insulation they use, really made a difference. House now retains its heat!Sally M. ★★★★★ Very quick service from start to finish. Had survey on the 16th October all done and dusted by the 24th!Had one hiccup! Van went over drain cover which broke resulting in wheel stuck down the manhole! Quite a feat to get the van out, nobody's fault just one of those things. Andrew reimbursed cost of new manhole cover with no quibble.Big Big difference in warmth in the house. Very pleased would recommend.lucksri h ★★★★★ Used Arrow Insulation for a cavity wall insulation job. Delivery team was professional and friendly. They did a great job on the day. From the quotation to the finish - it was an easy and satisfying experience. Happy to recommend.b b ★★★★★ Marian B. ★★★★★ Robert ★★★★★ Arrow installed cavity wall insulation to our property. They conducted a thorough survey and provided an informative report detailing the work to be done. Their price appeared to be competitive. The installation was brought forward by a week-or-so. The on-site team arrived late, due to weather issues. With work like this you can't really tell whether it has been done properly. However the on-site team were very professional and enthusiastic. They explained what they were doing, appeared knowledgable and tidied up the site afterwards. They were a good advertisement for the company.Malcolm S. ★★★★☆ Efficient and tidyMike H. ★★★★★ Cavity wall extraction and installation of bead insulation. Excellent service and whilst an unknown hole in the kitchen wall meant a considerable amount of dust that required 3 hours of cleaning by me this was unforeseen. Looking forward to now seeing the benefits of new wall insulation!Sheena J. ★★★★★ This company is fantastic from all the staff in the office to the surveyor. Lee and Shawn who did a very good job with the cavity wall insulation, they arrived on time and left our property clean and tidy.trevor J. ★★★★★ We used Arrow Insulation to provide insulation to the loft space and cavity walls to our home.We found the service to be first rate and all work was completed on the agreed dates with no drama.I would certainly suggest that you should give Arrow Insulation a chance to provide a competitive quote for your Insulation projects.Linda P. ★★★★★ Cavity wall insulation. Dan and Frank arrived at the specified time and were very polite and professional. I think it may have been Frank's first day as Dan was clearly in charge and between them they did a fantastic job :). Over and beyond.Ian M. ★★★★★ these guys did a great job.... turned up early, protected everything in the house with plastic, explained everything, uncovered a few other issues that they addressed.... very pleasedKit F. ★★★★★ Prompt response, helpful and left house tidy!Adam B. ★★★★★ Pair of very helpful, polite chaps did our cavity wall insulation. Tidied up nicely after themselves and we can already feel the difference in the house, thank you!Jano B ★★★★★ Excellent service. Information provided was comprehensive and staff very responsive. Technicians were polite, friendly and efficient. Would highly recommend.markiball ★★★★★ Frank from Arrow Insulation came and did my cavity wall insulation. Prompt, friendly, knowledgable and I cannot recomend highly enough. Communication with personable Samatha in the office was also very straight forward. A breath of fresh air in the current climate.Mark Ball, HorshamSven S. ★★★★★ Super professional company from start to finish. Very friendly and great customer service. Very tidy work and really no trouble at all. They are the kind people you want to work withRowena G. ★★★★★ Arrow have been totally professional from start to finish of the process. Scott provided an in-depth and clearly understood, value for money quote. He arranged a timescale to fit in with our availability. The scaffolders were quick to install making a safe and tidy installation and have advised the date of removal too. Rob the electrician was friendly and professional working in a clean and tidy manner showing respect to our home at all times. All components are of high quality and installed in a neat and tidy manner very pleasing to the eye.The Solar panel fitting team also carried out the installation in good time and in a tidy manner. Both Scott and Rob have supported us with the workings of the apps and advice for the future tariff choice which will provide us with the best returns from the grid payments. All in all an excellent service which I would be happy to recommend to friends and family. Thank you.jeffrey M. ★★★★★ Wonderful service by the whole Team..Matthew H. ★★★★★ Used Arrow for beads insulation. Cannot fault them, hiccups with vans etc. but they accomodated and squeezed us in to meet deadline. Would highly recommend!simon L. ★★★★☆ I used Arrow for both cavity wall extraction and cavity wall insulation. The installation was great, the guys were very fast, turned up on time and the communication was great, they were generally tidy and did a good job. I had a few issues with the extraction because of a surveryor, but the team sorted it out fairly quickly and managed to do the job. I would use them again.Andy F. ★★★★★ We used Arrow to provide spray foam insulation to our loft and garage; also cavity wall insulation to the main structure of the house. The house was built in 1939 and had mostly cavity walls but the original ones were uninsulated. The loft had some fibreglass insulation which was not adequate.Arrow, in the shape of Andrew Woodruff, provided a clear and straightforward appraisal of our insulation needs. His report made sense, the proposed actions were proportionate and the price quoted was very reasonable. Certainly much more reasonable than the quote we'd had from another company who came on with the hard sell techniques!The insulation teams came on successive days in early January 2022. They were cheerful, polite and professional, listening carefully to our requirements and making sure we were happy with the job they had done. Already the house feels warmer and our heat pump even more effective. We would thoroughly recommend Arrow to anyone wanting this type of work.Robert B. ★★★★★ Arrow insulation installed cavity wall insulation at my property. They were very professional and courteous throughout and I'm very satisfied with the work carried out.Jean B. ★★★★★ Just had cavity wall insulation installed at our house. amazing ! the staff were friendly, efficient and did a great job, you can't even see where they drilled the holes in the brickwork. Would definitely recommend this companyMark H. ★★★★★ Two good guys turned up on time , very clean very quick with a finish on the drill holes that you cannot even find . Great company would recommend to anyonePhil K. ★★★★★ We used Arrow for cavity wall insulation. It took a bit of time to get a response initially, but once we did we found all staff very pleasant and efficient. Installation was quick and tidy. We can already feelThe difference in the warmth of the house two days on. Would recommend.Louise R. ★★★★★ Frank & Dan came today to carry out our cavity wall insulation, they were both really friendly & courteous throughout. They arrived slightly earlier as I had to leave to do the school run so that was really appreciated. After the work was carried out they cleared everything up & I would highly recommend these 2.The company itself were friendly, professional & quick at responding to queries & booking the appointments. Definitely a company you can trust. Thanks!Ian S. ★★★★★ This company is outstanding. I made contact with Andrew and discussed our need for Cavity Wall insulation. Our house was surveyed the same day and a cost given. The work was done a few days later by an excellent team. Excellent communication and excellent service. I can't recommend this company enough.M D ★★★★★ Excellent job. Very efficient process throughout. Andrew was quick in responding to any queries and clear in the steps and preparation for cavity insulation. This was important as I needed to pass details to our tenants so involved extra people to coordinate.David H. ★★★★★ We've just had the cavity walls of our property insulated with the Thermabead product, taking advantage of the Government's Green Homes Grant.The service and communication provided by Arrow was superb, although it turned out that the actual work was sub-contracted out to a company called Evolve Home Energy Solutions. Once Arrow had done the survey and taken our details the rest was handled by Evolve, including the installation. This wasn't immediately obvious at the time of ordering the insulation, but in the grand scheme of things it didn't really make much difference – it just added an extra link to the communication chain.There was a frustratingly long delay between having the survey carried out (4th November) and the insulation being fitted (10th February), but this was almost entirely due to the speed the Green Homes Grant voucher was issued. It didn't help that Evolve were the ones handling the voucher application as they were very slow to respond to enquiries, unlike Andrew from Arrow who almost always replied to my emails on the same day.Overall Evolve seemed to do a good job of installing the wall insulation (it's hard to see it as it's all inside our walls!) and seemed knowledgeable and experienced in the process. They did a good job of tidying up after themselves too.We're pleased to finally have the extra duvet around our house and wouldn't hesitate to use Andrew and Arrow Insulation for other insulation requirements.Bruce F. ★★★★★ THERMABEAD CAVITY WALL INSULATIONArrow Insulation’s surveyor Andrew did a very comprehensive survey and explained the whole process very clearly. It was really easy to communicate and deal with Arrow Insulation. I chose them because of their amazing reputation and because they install Thermabeads. Their prices are also very competitive.Our installer was Frank. He’s one of the friendliest and most genuine people that you could ever wish to meet. He was really happy to answer all of my questions and explain the work which he was going to carry out. He did a really thorough job and left everywhere clean and tidy afterwards.I highly recommend Arrow Insulation as a first-class cavity wall insulator. Thank you so much…YoungOnes ★★★★★ Thermabead Cavity fill and Knauf loft insulation, a very good service inlcuding removing old foam insulation from the cavity.matt P. ★★★★★ The whole Arrow team were professional and efficient from the initial contact, the site survey and installation.The survey team were quick to come out and explained everything in detail with no pressure to continue.The installation team of Sean and Lee were very professional, tidy and efficient. Once the job was complete, you couldn't tell they had been.Highly recommended for anyone requiring cavity wall insulation.Stephen L. ★★★★★ Arrow managed the installation of replacement cavity wall and loft insulation for our property. I would strongly recommend ensuring your insulation is up to standard as it is the hidden armour in ensuring your home heat loss is minimised and ultimately this is a real significant frontline, positive activity you can implement for helping to ensure your personal carbon emissions reduction is impactful. Arrow are definitely worth a punt as they and the installers they use are very professional.Julian K. ★★★★★ We have a 1960’s bungalow that always felt cold and damp and discovered that the cavity wall insulation was the poorly filled woollen fibre type. Looking for a local Dorset-based business that came with good reviews we came across Arrow that provided both the extraction and fill service we needed. Matthew first came out to survey the cavities and was very thorough and helpful in explaining the situation and what Arrow could do to help, and swiftly followed up with a quote for the works. No pressurised selling. Carly in the office was really helpful in arranging the works that would take place over two days, with the extraction team having to go about their business on a day when it poured with rain all day. How they stayed smiling and cheerful all day was beyond me. The cavity fill team the next day were as professional as the team before and left our property clean and tidy. I have no hesitation in recommending Arrow and our property now feels warmer and drier as a consequence of their hard work.russell W. ★★★★★ Would recommend Arrow Insulation for cavity wall insulation Frank and his team were very efficient and cleaned up well. The price was good too £400 cheaper than the Warmer Group.👍Rachel A. ★★★★☆ This was cavity wall insulation - prompt and extensive commnication before amnd after job and job done with minimal fuss.Alison B. ★★★★★ These guys could not have made the process any easier ! From the initial enquiry they were swift to respond and extremely professional and helpful throughout. The extraction and insulation team were punctual , very respectful and left the site clean and tidy.Would definitely recommend. Thank you !Mike K. ★★★★★ Arrow have been nothing but perfect throughout the process. The extraction team (old insulation removal) where fast, efficient & tidy. The guys that came to install the bead insulation Sean & Lee arrived on time, informed me of the work scope, gave me a detailed explanation of how the job went & left the walls in a perfect condition for the rendering team to complete their task. First class service from a very professional company.js_loader
