About

RJ Insulation specialise in ECO friendly, natural and sustainable loft insulation.

Pre 1920 homes.
One of our assessors holds a Level 3 award in giving advice on energy efficiency measures to listed and traditional buildings.

He recommends using the Sheepswool. Sheepswool is hygroscopic, therefore is specified for listed and traditional buildings.

1920 -1960s homes.
For 1920 - 1960s homes we use SuperFOIL Insulation. SuperFOIL is designed to keep you cool in the summer and warm in the winter. SuperFOIL states that it can increase the value of your home.

Post 1970.
For 1970s or later we offer the SupaSoft Insulation. Supasoft is made entirely out of single use recycled plastic bottles. on average it takes 10,000 - 15,000 Single use recylced plastic bottles out of landfill and into your loft. It never degrades and is approximately 11% more thermally efficient than the typical Fibreglass.

We give out a lifetime guarantee for SuperFOIL, Sheepswool and Supasoft

From the start of my original enquiry to the end of the installation itself, nothing was too much trouble. Alfie was helpful, explained everything and went out of his way to sort any concerns. The quote was done efficiently and installation time after was almost immediate (week later). The installation team were clean, tidy and efficient as well as understanding. They arrived at 7.45am having left head office at 5am and left 11am. Again, nothing was too much trouble and the work was carried out as detailed on the quote. I will not hesitate to recommend.

I cannot recommend this company enough. From the initial chat with Alfie through John and the fabulous installers this was as smooth as clockwork. Firstly the product is great but we probably knew that already. More importantly the clarity and professionalism of everyone involved made this a really pleasurable experience. We live in an old house, fridge in the winter, oven in the summer and what often feels like pretty poor air throughout. Although we’ve not had any great temperatures to truly test this out the air already feels tangibly cleaner and the temperatures more constant. It will undoubtedly be an improvement through the colder months but is also making a big difference now. Alfie was very open, knowledgeable and engaging throughout and the installers were friendly, punctual to the second and really went the extra mile with the clean up as well as doing a fabulous job with everything else. I’ve never had a better experience with a company than this and can’t speak highly enough of both product and service.

The experience I had with R J Insulation was wonderful. When I initially contacted them for a quote I got a full run down regarding the service they provide as well as the different materials they offer, and they were happy to answer any questions I had and explained all their certifications. I was given time to research everything and I genuinely think they wanted nothing more than to offer the best service. Although when compared to other installers and insulation types it may be more on the expensive side for initial cost, I think it's worth every penny as not only do you get a lifetime guarantee, you get the extra knowledge that your insulation is made of recycled or eco-friendly materials. Having had SupaSoft installed it's also good to know that the insulation will last long after I've moved from the house. I got my loft insulated with the recommended amount of SupaSoft insulation as well as about 8 square metres of lifted boarding added for storage. The installers arrived on time on the day and were clean, courteous, and finished everything well before the expected completion time. They double checked with me where I wanted the boarding put as well as discussing how to deal with my push-up loft hatch. When the job was finished everything was tidied up and hoovered, and I think my carpets are even cleaner than when they arrived. Overall, I had a wonderful experience from start to finish and wouldn't hesitate to recommend them to anyone considering loft insulation.

From the initial contact to the completion of the work all concerned were courteous, informative, professional and thoughtful. Our needs were discussed at length and advice and suggestions to meet our needs explored. The RAMS assessor visit prior to the work was informative and all our questions were answered. The four gentlemen that carried out the work were efficient, hard working and kind and completed the work within the time scale given and left the place spotless. Already the we can feel the difference in temperature throughout the house. As we continue with our project we are looking forward to working with the company again. Thank you.

I had a fantastic experience as a customer right from the moment I contacted them regarding enquiries about insulating my loft. Each insulation option was explained clearly to me including the advantages and disadvantages of each potential product. When I made my decision on the best option for me, the whole process was broken down to me in clear, easy to understand steps. They were able to accommodate a date which worked around my work calendar which I really appreciated. The two team members who attended my property to carry out the work were very friendly, professional and polite. The work they completed is of a high standard and they left my property in a great condition. The follow-up conversations I had with the company were informative and all email correspondence I’ve had which contained invoices and certificates have all been correct and professional. Overall, I would highly recommend this company if you are looking at insulating your loft!!

RJ Insulation sent an excellent team who were very hardworking, diligent, polite and respectful. Indeed unusually for a building project it was a pleasure! The outcome is exactly what I wanted but was unsure could be delivered to this highest of standards. The skill standard, quality of work and the use of sustainable materials, though costly, is value for money. I have an amazing beautifully finished space - well decorated and with a really good Novocore flooring that is both beautiful and practical. RJ were happy to use my paint of choice, Little Greene and came up with a brilliant solution to my request for simple easy access fitting a fully remote controlled Loftomatic ladder system. It is awesome and will mean I will be able to access the space easily making it really usable. I am beyond delighted - it was worth the time and money. RJ put a lot of effort into the planning and ensuring they understood my needs so they could deliver exactly what I wanted. They excelled and have gone above and beyond! I will definitely be using them for any future insulation work and highly recommend them to make your loft a usable space.

Very happy with the work done, and the customer service received. The two chaps that came to do the insulation were very pleasant indeed, they were clear on what they were doing, and kept everything clean and tidy. Really pleased that I took the January discount offer. The house feels much warmer already, and the boards are now much better secured. I wasn't pressured by the sales team and was given plenty of information and time to decide. Really pleased I made decision to use RJ Insulation via Top Up Insulation.

The loft insulation in our 1900’s house was poor with the existing loose boarding laid directly on top of it. In researching upgrading the insulation I came across SuperFOIL insulation and contacted R J Insulation to discuss. Alfie talked me through the product, the quotation and installation process and after providing a few details shortly came back to me with a quote with a small range. By installing SuperFOIL it would mean that the existing insulation didn’t need replacing nor the boarding. After agreeing to go to the next stage, a member of the team visited within a few days to conduct a risk assessment and to firm up the quote. Alfie then confirmed the price, which was within the initial range suggested. After agreeing to proceed, a date was fixed for the installation within a couple of weeks. The installation team were punctual, polite and friendly, protecting our carpets with sheets and vacuuming when they had finished. They also removed a couple of redundant water tanks from our loft. The work was completed on time and to budget. We noticed some immediate improvements after the installation - drafts in the loft were eliminated, our first floor rooms felt warmer, noises from outside were reduced and the loft looks great! Hopefully we will also see reduced gas bills in due course. I thoroughly recommend the product and R J Insulation.

R J Insulation carried out phase 1 of my 3 phase loft insulation project back in 05/10/2023. The review I wrote then will be similar as this one. The professionalism is exemplary, from making contact through all processes such as quoting, customer acceptance, agreeing timescales and payment. I sought out the company because I was unable to find a local firm willing to undertake the type of work. I turned to Which? and immediately felt comfortable in knowing they were a Which? Trusted Trader. Phase 2 of my project was all about lifting the boarding, disposal of the existing felt insulation, laying down 'SuperSoft' insulation and reinstalling the boarding. This was undertaken by the original 3 chaps who had previously installed Phase 1. They were punctual, professional, very hard working and were excellent at leaving the property clean. There were no issues whatsoever in all of the processes. I am very happy to recommed the company, and will be returning for the final phase of the project.
