    Purchase your rooflight from Ofset, you won’t regret it!

    I would not hesitate to recommend Ofset to anyone. Their products and customer service are second to none. It took one phone call to Ofset to get our project back on track. Ziggy was exceptionally understanding. He listened to our needs and helped us to select the spec that best suited our build. The whole process from placing the order to instillation was seamless and incredibly quick. It was a breath of fresh air to know that we could trust Ofset to provide a competent, professional service. I have never known an individual be as responsive to messages as Ziggy. He replied immediately to all queries and is clearly an honest and trustworthy individual. Everyone involved with the install on the day were incredibly professional and completed the job flawlessly. We couldn’t be happier and are so grateful that we ditched our old supplier. This rooflight is STUNNING. Purchase your rooflight from Ofset, you won’t regret it!

    Bladey Brilliant

    Perfect through the whole process! After being messed around for months by a large roof light company we decided to contact Ofset. 2 days later we had ordered a blade, Ziggy & Aleks made the whole process incredibly easy, from showing us the options through to confirming the order. We were given an install date and when the day came the fitters were on time, very friendly and efficient. The whole process from craning to the final install only took about an hour and a half. Incredible, highly recommended!

    Great service from start to finish

    Great service from start to finish. Ziggy and his team went the extra mile to turn this around from initial enquiry to installation in super quick time to assit us with timescale pressures we were under. Install team were super efficient aswell, all round top job well done all.

    Steve H

    Fantasic Company to deal with

    Agreed an installation date well in advance and stuck to it. Ofset arranged the crane and the installation and all went incredibly smoothly. Really well organised which takes away a lot of hassle from the customer. Pleasure to deal with. Incredibly happy with the end results. The skylight looks fabulous.

    Khalid B

    The best skylight available

    Absolutely superb company to deal with. Extremely professional and keep you informed at all times. The coordination of different contractors on the day of install was faultless. The finished product is the best on the market and incredibly competitive. Simply the best. I wouldn’t look anywhere else.

    Sanjay S

    Brilliant and highly professional service

    Brilliant and highly professional service from service from Ziggy and team from start to finish. Seamless process from engagement, design, production and installation. Ofset provided 2 large blade rooflights for our refurbishment project in Luton which look amazing, a very high quality product and service. Looking forward to working with Ofset on many more projects in the future.

    Rooflight installed in record time

    We had an old leaky roof lantern which was letting in drafts and snails. After a few rain delays, which is just life, we now have a beautiful new rooflight installed in record time. The space feels so much bigger and it is already noticeably warmer in the kitchen now. Thanks so much we love it! Great team and great communication.

    Elinor J

    Perfection in glass and alumnium

    It makes the space look so open and bright. Installation was a dream. The team were professional and quick - from the arrival of the crane to the final polish was about ninety minutes! The rooflight itself is sleek and beautiful. It makes the build look incredibly high end.

    Gursharon B

    I must admit

    I must admit, from start to finish, Ziggy and the whole team at ofset made this experience so easy from start to finish. My vision was brought into reality with the ease of delivery and installation by Mark, Jack and Reece. Thank you everyone at ofset, the service was excellent and I cannot recommend them enough. Dream it, do it. Well done to everyone involved.

    Dariush H

    Extremely happy with the installation

    Extremely happy with the installation. Everyone who has seen the roof lights has comments they are the nicest they have seen as they are completely flush in a pitched roof. The installation team lead by Mark were amazing.

    Paul B

    Great service and product!

    Ziggy and the team at Ofset did a great job designing and installing our three large rooflights. Ziggy was the most responsive service provider I have ever dealt with - nothing was too much hassle for him. The rooflights look great in our newly developed home!

    JSH

    Huge roof light!!

    We decided on a 5m x 1.5m skylight which is obviously quite big, and weighs 475kg! Now fitted and looks absolutely superb, gives lots of light and creates an airy and bright welcoming space. The Ofset product is sleek and elegant, fitting time was very quick, the fitters themselves were very experienced and left the site in a clean and tidy manner, would certainly recommend Ofset if you’re after a modern crisp elegant rooflight

    Steve M

    Tricky Job, Tricky Time Frame - no problem for OFSET

    I wanted a supply and fit solution to replace 3 old, large roof lanterns that were in very bad repair. I was surprised how difficult it was to find someone who would take on all aspects of the work in one go - removal, install and even the crane delivery. The work was carried out on the day that was agreed despite the tight timeframe and the workmanship was excellent - matching the ofset blade product that we had installed. It looks great from inside and out. It is just a shame that only the birds will see the outside!

    Paul R

    Excellent rooflight installation

    Very easy to deal with. Team arrived on site as agreed and all four rooflights installed in one day. Ziggy is very responsive and easy to deal with.

    Stephen M

    Excellent Design & Installation Service

    Ziggy and the Design Team ensured our clients requirements were met. As a Main Contractor with 25 years experience, the Blade is without doubt one of best Rooflights on the market. Even with a 400 mile installation in Scotland, the fitters even visited the job the night before. With a 100 ton crane installation, everything went smoothly and the client has a bespoke product they are delighted with. Highly Recommended.

    Paul H

    Perfect bespoke installation

    Huge shout out to the team at Ofset (Ziggy, Mark, Jake, Adam, Kev, Kieren and Jim on the crane) for a professional and perfect bespoke installation by a well organised crew. My blade has completely transformed the living space in my house. 10/10

    Kim Q

    A fabulous product

    Ziggy and his team delivered and installed a magnificent pair of huge three metre by two metre roof-lights in our renovation project. The skylights look fantastic and will become an integral feature of our home. Thanks again for producing a fabulous product.

    Emma D

    Absolutely recommend

    Ziggy/Ofset have supplied us with two large Blade rooflights and have been a pleasure to deal with the whole way along. The rooflights arrived in exactly the timeframe we requested, and the fitters noticed a minor issue (that we didn't) and Ziggy arranged for replacements straightaway (none of which delayed our project). Their professionalism and the product itself is exactly what we hoped for.

    Lizzy J

    Traditional and modern

    We have just had our blade roof light delivered and we are over the moon with it. Ziggy has been really helpful from start to finish, helping us achieve our final design. The shape is a nice intermediate between traditional and modern. The delivery team made the installation seamless. The blade is as beautiful as we had hoped. Would highly recommend.

    Roger G

    Fantastic job, quality service

    💯. Ziggy and his team have just installed 9 massive rooflights at our property. From start to finish the service has been excellent and the installation went great with no hitches. Quality product from a quality company that we will definitely be using on future projects. Well done Ofset

    Charley E

    Super quick turn around

    Just had a rooflight installed by Ziggy and his team and it is stunning. The product and service were both excellent. They stepped in and turned around the order in super quick time. Ziggy was always on hand to help with any questions. Would not hesitate to recommend to anyone. Thanks guys.

    Charlie S

    Great product and service

    We first saw this roof light at our architects house and knew we had to have one. The team turned up and installed on time. The fitters were excellent and along with the crane driver was seamless. Would highly recommend.

    John J

    Ofset roof light

    Wow what a great bit of kit that was true to the brochure. It fitted like a glove the crew Ziggy (owner) sent were fantastic they made the job look so easy. Even my builder was impressed and he seen many roof lights over the years, so impressed that he will be using and recommending Ofset to others. It stylish and crisp looking well with the price.

    Nic C

    Amazing large rooflight

    Fantastic roof light installed by the team expertly lead by Ziggy. Nothing was to much trouble and the quality and design is second to none! Fantastic company & product

    Copier K

    Great product that's a show stopper

    Great product and service. We first saw this roof light at our architects house and knew we had to have one. After talking through and ordering the blade system with Ziggy, we was supplied all the drawing for our builders. When the roof was ready, the team turned up and installed on time. The fitters were excellent and along with the crane driver was seamless. Would highly recommend.

    Greg L

    Perfect service and perfect product!

    From the smooth ordering process and excellent customer service throughout to the faultless installation of a beautiful end product, everything has been perfect. I would highly recommend Ofset roof lights. Well done to Ziggy and the team!

    Bill C

    Simply the best! Don’t bother with any other supplier!

    Brilliant product. Delivered on time and installed perfectly. I have used many roof lights over the years but this is by far the best!

    Quality service and installation......great product with great effect.....thanks Ziggy and team

    3 x 3 x 1m blade rooflights

    We live on a flight path so needed some rooflights that offered decent acoustic properties and Ofset rooflights offered the best acoustic spec i could find. The fact that they are visually stunning as well sealed the deal. Ziggy kept us updated throughout the manufacturing process and up to the install date which was on time. On install day there was a minor hiccup outside of Ofset's control that might have delayed the install, however Ziggy and his fitters (who were excellent throughout) went the extra mile to ensure that they were in by the end of the day. We are over the moon with the blade rooflights, having been renovating for coming up to 4 years it was refreshing to deal with a professional company who delivered a stress free install.

    Peter Frost

    Excellent job

    It’s the first time we have dealt with Ziggy of offset. A great guy, punctual, reliable a great price and first class service. The product quality is spot on . I was previously advised (by a different supplier) that it wasn’t possible to supply a roof light this size in one sheet of glass ! Ziggy came to the rescue so he was also a life saver. No fuss just a perfect job. Thank you Ziggy and your wonderful team. We would recommend using this guy 100%. Peter Frost.

    Henry H

    We are over the moon

    The Ofset team have just installed a 2m x 3m rooflight. We are over the moon with it. Product quality is spot on. We really like how it gives the impression of there being 'nothing there'. It is our luxury item and we are really happy with it. The fitters turned up with all their gear and the crane on time, and it took them 1hr45mins from start to finish. Communication was great and all questions we had were answered promptly and accurately.

    Andy Q

    Great experience from order to installation.

    Great experience from order to installation. Really pleased with the three large floating blade skylights we've had installed, professional job by the installation team and a really high spec product. Good communication throughout and delivered to time and agreed quote. Highly recommend.

    Craig Driver

    Amazing quality product

    Architecturally an amazing quality product, amazing service, value for money and an amazing owner! This installation for my own house has already attracted a great deal of interest from colleagues in both architectural and construction circles; no doubt we will be specifying on other projects.

    Dr Bavesh Bodalia – Coventry

    Exact fit and looks amazing

    Great job. The Ofset team worked seamlessly with our builders and project manager from the first contact through to the final installation. The attention to detail from the initial advice to the on-site surgery, delivery and installation was reassuring secure and helpful. On fitting day, because of the size of the roof glass being installed, we were all a little nervous. The Ofset team arrived as scheduled and their professionalism and knowledge made the whole installation quite an exciting event. The glass was an exact fit and looks amazing. Thoroughly recommend Ofset to anyone undertaking such a project. Thank you Ziggy!

    Dr Phil Le dune – Tyne and Wear

    Minimal fuss

    We were so satisfied with our previous job that we used Ofset again for 2 Blade rooflights 2m x 3.5m. Minimal fuss, excellent communication , great product

    Les Williams Builders- Birmingham

    Unique and Stunning

    From the super impressive and informative website to the excellent communication from day one regarding order, product information, site delivery and install explanation. Ofset filled us with confidence that their product was the one for us to use. Not forgetting just how unique and stunning the product is, BLADE really is a thing of beauty, pushing boundaries and excelling in its design! No more generic roof lights for our projects going forward I will be recommending Ofset to future clients based on the excellent service and product we've experienced.

    Anthony Gudger- Misterton, South Yorkshire

    Ofset is a great company with a great product, would certainly recommend these windows.

    Ofset have just installed 2 roof windows, 3m x 1.2m. These windows look absolutely fantastic. It has been a pleasure working with the Ofset team, who was very knowledgeable. There was great communication and a well organised installation process (despite weather issues). Having done a fair amount of research, these windows are competitively priced, but the specification and style is far superior to the others. I would definitely recommend Ofset.

    Gareth Williams (Architect) – Devon

    Outstanding Service and Excellent Products

    Ofset supplied the rooflight for our new extension which has added an amazing feature to this space. The shape of the rooflight is irregular and we struggled to find a company who were able to supply this. Ofset were amazing and nothing was too much trouble. They communicated at every stage of the process and the service was outstanding. We have already recommended them to friends and clients and would have no hesitation in using them on future projects of our own.

    Alex F (Architect) – London

    Ofset - Quality Rooflight Installation

    Ofset are a high quality, thorough manufacturer of bespoke rooflights. They pay excellent attention to detail, and have completed a complex installation quickly, efficiently and on time. Their service was very high, with hands-on owner attention, which is rare. I would recommend them and will be working with them again in future.

    John Ingle – Cornwall

    Proud Owner

    I am now the proud owner of six new blade rooflights in my new build. The purchase and installation have just about been the only parts of my build that have gone smoothly. I had a number of quotes before ordering but all the others failed to come up with the size and spec that I needed. I found communication was frequent and personal, and can thoroughly recommend the company.

    Phillip L – Tyne & Wear

    A beautiful product

    Excellent communications , personal support, attention to detail and a team who are punctual , skilled and tidy!! We were very grateful for the ofset teams help throughout. Highly recommended

    Henry C

    British engineering at its best!

    Ofset have just installed a 3.2m x 2.2m blade roof light for me. The product is unique in terms of their ability to produce massive roof lights out of a single sheet of specially toughened glass. No joins or unsightly support beams just beautiful clear glass! The Ofset team are very proactive and hands on meaning you get a highly personalised service which delivers the installation on time and on budget.

    John Condron – Rutland

    We could not be happier

    We have just had 2 rooflights installed in our new extension. We could not be happier with the quality of the product, the professionalism of the installation ofset team and the attention to detail. They look beautiful, and let so much light in. They have transformed what would otherwise have been an ordinary build into an extrordinary one.

    John L

    Great rooflights

    Unique design, great service and the only company able to give me a reasonable quote for the size of rooflight I wanted.

    Jordan D – Norfolk

    Quite simply the best rooflight system I have worked with

    Experienced fitter with over 15 years experience recently had the opportunity to fit the blade rooflight system. As design and aesthetics go this is by far the best and most premium looking system I have come across, there's nothing else like it currently I'm aware of and to fit the system is simplistic and extremely rewarding once seeing the results once the fit is complete. I won't recommend any other high end system from now on ofset will be my choice.

    Karl R – Yorkshire

    Happy customer.

    Looked online for roof lights and came across ofset roof lights, did a online quote, prompt response, a stylish modern design, ordered and the service from the sales team was second to none. The build quality of the light is excellent, very pleased.

    Sara G – Surrey
