When you’re trusting a business with your belongings, you want to know you’ve picked the right one. So we wanted to share some news that says a lot about what’s been built at our Sunbury store, and the team running it.
Attic Self Storage Sunbury has just been named UK Multi-Site Operator Store of the Year 2026 at the SSA UK Awards, sponsored by Janus International. It’s an independently judged industry award, and the Sunbury team has won it for the work they’ve done since the store opened in June 2024.
We’re chuffed about the result. But more importantly, it’s one we think our customers — current and future — should know about, because it’s their experience the judges were really looking at.
What the award recognises
The SSA UK Awards are run by the Self Storage Association UK, the trade body for the UK self-storage industry. The Multi-Site Operator Store of the Year category judges across four areas:
- Facility quality — the physical standard of the store
- Local integration — how well the store has become part of its community
- Business performance — occupancy, growth, and commercial results
- Customer experience — what real customers say, unprompted
To win, a store has to deliver exceptional performance in all four areas, which Sunbury did.
From dated factory to modern storage facility
Attic acquired the Sunbury site in August 2023. Rather than demolish and rebuild from scratch, the team chose to convert the existing building — the more sustainable choice, keeping the embodied carbon of the original structure in place, but also the harder one.
The work involved:
- Stripping out the partial mezzanine and replacing it with a new full-span structure to maximise lettable space
- Re-laying the entire ground floor for a consistent, bright finish
- Removing the original peeling cladding and replacing it with fresh cladding in our brand palette. The team also painted the redbrick work to give this a fresh new look, also brining it in line with the brand identity.
- Installing app-controlled locks across every storage door and access point.
Less that nine months from acquisition, the store opened in late May 2024.
The transformation our construction team have achieved on this building is outstanding. They’ve taken a very tired building and turned it into something with a premium look and feel — externally and, just as importantly, internally too. They’ve delivered a product that exceeds customer expectations.”
– Sophie Bagnall, Marketing Director, Attic Self Storage“Big thanks to the team for making the sales look easy and the panic look organised. This award belongs to the entire team and reflects the hard work everyone contributed towards.
My main goal for the Sunbury team was to achieve, or at least get close to what Beckton achieved in the past. We all know that teams evolve, markets move, and plans can quickly be torn apart, but the way the team handled every situation, grew professionally, and most importantly learned from each experience, has been incredible to see.
As Voltaire said, ‘Change is annoying. Certainty is absurd.’ But one thing I am certain of is that the Sunbury team will continue to deliver excellent customer service and achieve their goals.
Well done and congratulations to Leigh, Angela and Peter for this amazing achievement.”
– Ecaterina Davidov, Store Manager, Attic Self Storage Sunbury
Customer Reviews
In the short period of time since opening, the team have managed to drive 549 Google reviews (as of May 2026)with an average rating of 5.0 stars, a phenomenal performance. The team have also achieved a 99% recommendation from Net Promoter.
Built into the local area
Storage is a local business, Attic Sunbury sits at Junction 1 of the M, with around 210,000 people inside a 10-minute drive – but easy access doesn’t make you part of a community.
The Sunbury team put effort in from day one to integrate the store and themselves into the local community. The store launch was opened by the Mayor of Sunbury and catered by food-waste charity Surplus-to-Supper. It set the tone for everything that followed.
Here are some of the initiatives that the team have implemented to further support the local community.
Cooking for a Cause
A launch campaign with London chef Dipna Anand, Sunbury Cricket Club, and Surplus-to-Supper. For every meal sold, one was donated. The campaign raised over £1,800, generated nine pieces of press coverage with a combined reach of more than three million, and the recipe still lives on our site.
Charity door-drop campaign
Local residents voted for the causes Attic would support, resulting in £2,000 in donations to charities chosen by the Sunbury community itself, including Surplus to Supper, Sunbury & Walton Sea Cadets, Home-Start Spelthorne, Charley Paige Trust, Hilary’s Hut and Thames Sailability & Impossible Dream.
We also donate £5 for every customer who moves in, with over £4,300 donated to Surplus-to-Supper to date. That number keeps growing.
Spelthorne Festival of Lights
Attic sponsored the local festival as part of our ongoing commitment to the area.
High-street presence
Door-drops, branded carrier bags in local cafés, posters in newsagents, and keyrings with local key cutters. Small things, done by the store team, that put the brand onto the high street rather than just onto a billboard.
Security, access, and sustainability
Security and access
The site is fully perimeter-secured with fencing and brick wall, entered via two gates — one for cars and vans, one for larger lorries. Inside, every unit has its own individual alarm. The building runs 24/7 CCTV monitored remotely by DSOC, with customer emergency call points throughout.
Access is via our app— complimentary, and available 24 hours a day, 7 days a week. The team is on site seven days a week.
Sustainability
Converting the existing building rather than demolishing it kept a meaningful amount of embodied carbon in place. The store runs on 228 solar panels, LED lighting throughout, and is working towards BREEAM In-Use certification. It’s the most sustainable approach we could have taken on this site, and the work to keep improving is ongoing.
