What Our Customers Say
Reliable, secure and aesthetically pleasing
I discovered Finfort locks whilst researching the market for a reliable, secure and aesthetically pleasing lock for my front door. The product offerings looked great and example videos of the lock functions were very useful in deciding which lock to go for. Hilary was very helpful in providing advice and answering any questions I had, she also assisted with putting together a custom package for me which matched my needs exactly.
Great customer service
When I renewed my home insurance, I found out my old deadlock wasn’t BS3621 compliant. I emailed photos of my door to Finfort and they got back quickly with advice on options and costs — great customer service. I ended up fitting their Manual Deadbolt with solid lockguards — it feels properly secure and looks it too.
Exactly what I was looking for
Not the cheapest, but outstanding service and an excellent quality product.
