The two of us.
SAHN is a small, family-run service based in Peterborough. We help people set up their home properly — visiting, recommending the right products, installing everything, and staying in touch afterwards.

Safwan Chowdhury
Hi, I'm Safwan. I'm a software engineer with a Master's in Computer Science from Imperial College London, and I've built up more than ten years of experience with AI and smart-home technology, often alongside some of the best researchers and engineers in the field. Most of what I know comes from living it, years spent automating my own home, testing products, and learning where this tech helps and where it just gets in the way. My advice is honest and practical, shaped around your life rather than the latest gadget.

Hasnain Ali
Hi, I'm Hasnain. I'm an Electronics Technician with a degree in Mechanical Engineering from Coventry University, where I specialised in control systems and electronics, and I've spent years in home renovation and hardware. I handle the build side of your home: the installation, the wiring, and making sure everything is fitted properly and finished to a standard you'd be happy to live with. A big part of that is planning around you, fitting the work to the rhythm of your day so the technology fits your routine, not the other way around.

SAHN.
/sɑːn/ · noun
the open courtyard at the heart of a home
Architecture
In Arabic, sahn (صحن) is the open courtyard at the centre of a traditional home — the space every other room was organised around. It gave the house its rhythm. We named the company after it because that is what we are trying to do: give every home a centre, a point from which everything else moves together.
Technology should serve the house. Not the other way around.
We started SAHN because we kept seeing the same problem. People were spending serious money on smart-home technology and ending up with something they didn't understand, couldn't use properly, and had to call someone out to fix every few months.
The market has become overcrowded. Too many products, too many variations, and not enough honest guidance. Most of the people who came to us wanted a smart home but had no way of knowing where to start — what it really cost, which products to begin with, or how any of it fitted together.
We do things differently. We visit first. We listen. We plan before we touch a single cable. Then we build, check, and hand over properly — staying available long after the job is done. Every home we work on has two people behind it, not a rotating cast of subcontractors.
That is what SAHN means in practice: a home where the technology disappears into the walls and just works.
