Cassette blackout blinds use a specialised cassette and side-track construction that seals the window, eliminating the light leaks around the edges that standard blackout roller blinds can't fully prevent — a useful upgrade for the floor-to-ceiling glazing common in Elephant and Castle's new residential towers.
Kelly's Blinds fits every cassette system made to measure, ensuring the tracks are perfectly aligned so operation stays smooth and the light blockage stays total, in apartments near Elephant Park and meeting rooms near Strata alike.
With so many different building types packed into a small radius around the SE1 and SE17 postcodes — new towers, converted units, university buildings — no two cassette blackout blinds installations are quite the same, which is why every cassette track system specification is agreed on site, not over the phone.
Our fitters carry a working stock of common cassette track system components on every visit near the SE1 and SE17 postcodes, so a straightforward cassette blackout blinds installation rarely needs a second appointment just to fetch a part that should have been anticipated the first time.
We quote against the actual window, not a price list category, which matters near the SE1 and SE17 postcodes where floor-to-ceiling glazing, standard sash windows and awkward angled openings can all sit within the same postcode. A site visit before fitting means the cassette track system is confirmed against the real opening, not a floor plan that may have changed during construction.
Because the fabric is held securely within side channels, cassette blackout blinds avoid the 'halo effect' of light common with standard roller blinds — a tailored architectural solution that blends seamlessly into the window frame.
The premium fabrics used act as a thermal shield, reflecting the sun's rays in summer and providing extra insulation in winter. The side-track system also makes these blinds significantly more resistant to airflow than standard designs, keeping the fabric stable even with active air conditioning or mechanical ventilation.
Multi-window apartments and open-plan offices near the retail podiums around the town centre need every cassette blackout blinds installation to match — same fabric batch, same mechanism tension, same finished drop — otherwise the inconsistency stands out immediately in a room with several windows side by side. Our fitting team measures and orders every window on a project together, rather than treating each one as a separate job, precisely to avoid that mismatch.
The same discipline applies to timing: because so many of the area's buildings are still completing their final fit-out stages, we schedule cassette blackout blinds installations to fit around other trades on site, backed by our quality fitting guarantee regardless of how tight that window turns out to be.

Posted on Google Linda Lovely guys, very efficient.Posted on Google Nayia Yiakoumaki From enquiry to installation, we have been very happy with Kelly's Blinds. Marek who was our first point of contact, is very professional and reliable, and so were his team who came to fit the blinds. Much more affordable than the bigger brands and the blinds look great.Posted on Google Natasha Peachey Kelly's have provided blinds for both our private and rented accommodation and years on they are still looking good. I had to replace a couple of brackets recently and their service was still quick, efficient and very helpful. Happily recommend this company.Posted on Google Jacky Healy I can highly recommend Kelly's Blinds, having used them many times now. Huge selection, excellent quality and great customer service from start to finish. Best of all, they come out to measure and fit, all included in the price, so you are guaranteed of a perfect finish. Just to add - 3 years after the original installation I had a slight problem with one of the blinds. Kelly's came out the very next day to sort it out, and at no charge to myself - you can't get better customer service than that!Posted on Google UK Succulent Great experience. The blinds I bought are excellent quality and they even installed them to be automated. Would recommendPosted on Google Andy Cameron I’ve used Kelly Blinds several times over the years and I am happy to recommend them. This time we had some vertical blinds and roller blinds installed, a great selection and fast professional service from the quote to the installation. At a great price too. I’m about to use them again for a rental property. Thank you Marek and the teamPosted on Google Abrar Mirza Highly recommend these guys. Their products are top quality. Had blinds fitted over 5 years ago and they’re still operating superb. Very professional, efficient and great customer care. Would definitely use them again.Posted on Google Alex 100% highly recommend. I got a few quotes from big names likes Hillary’s, but they significantly higher and I have to say; clearly are trading on brand rather than value. Kelly’s service and product are both amazing. I bought my blinds 5 years ago and couldn’t be happier. The first time I needed help was recently and they came round and sorted it straight away. I purchased 3 custom electric roller blinds and a manual one (for my balcony door) for the main room and a blackout electric blind for my bedroom with a home hub. They gave amazing advice, are super professional, and incredibly easy to deal with. I’d highly recommend them.Posted on Google Aaron Gaide We’re in a new build space and incrementally working on separate rooms. These guys have provided great blinds and very fair pricing. Instillation teams were professional, fast and did really quality work. Highly recommend for projects large or small.Posted on Google Tushar Adhikary Update(2026): Again have to call out the superb and quick customer service these folks have. Any small change or fix you need and these guys are there to help out. Highly recommend them. The quality and workmanship exceeded my expectations. I’m extremely satisfied with the outcome. Glad I went with them. Look no further if are looking for blinds/curtains. Update: I had a minor thing to fix with my blinds and the customer support was absolutely wonderful. They were quick and swift to help. This is the kind of customer obsession that makes these people better than the rest. Look no further.

Floor-to-ceiling glazing and larger window openings are common in Elephant and Castle's newer residential towers and commercial blocks around Elephant Park and Strata — exactly the conditions where standard blackout rollers struggle to achieve a full seal.
Cassette blackout blinds are the practical upgrade, professionally fitted for a total light block and a neat, integrated appearance.
That pace of change also affects how a fitting service needs to operate day to day: access arrangements, building management contacts and even street names around the retail podiums around the town centre can shift as each phase completes, so a supplier that only ever worked from an old site plan quickly falls behind.
For facilities teams and letting agents, that means a fitting partner who can adapt to a building that is still, in effect, being finished — coordinating around other trades near the retail podiums around the town centre rather than expecting a fully settled site.
It also means demand is genuinely mixed rather than seasonal: new occupiers are moving into buildings near the retail podiums around the town centre throughout the year, not just at the start of a typical moving season, which keeps our local fitting schedule busy on a rolling basis.
A meaningful share of our cassette blackout blinds work near the retail podiums around the town centre happens while the surrounding development is still active — scaffolding, site traffic and shared access all factor into how we schedule a visit, rather than assuming a quiet, finished street.
That experience means fewer delays and fewer wasted appointments, which matters when the cassette track system has already been cut to size and a missed access window pushes the job back by a week.
We'd rather spend an extra few minutes confirming the cassette track system specification on a pre-fit visit than turn up to install the wrong cassette blackout blinds on the day. Near the retail podiums around the town centre, where several similar-looking window types can appear across one development, that extra check avoids the reorder delays that generic suppliers often pass on to the customer.
It also means the quote given at the start of the process is the price paid at the end, with no last-minute surcharges for a fabric substitution or a mechanism upgrade discovered only once our fitters are on site.
