What people say about our services

Daniel Wright
“We called OSO after another company left us with a dangerous electrical job. The engineer came within the hour, fixed it properly, and the price was almost half of what we had already paid.”


Aisha Khan
“Water was pouring through my kitchen at midnight. I expected to wait until morning, but OSO sent someone straight away. Quick, calm, and very reasonable for an emergency.”


Sean O’Connor
“Our boiler stopped working on the coldest day of the year. The engineer turned up same day, sorted it in one visit, and made sure everything was safe. Really solid service.”


Amelia Rossi
“Other firms tried to make our drainage issue sound worse than it was. OSO just got on with it. They told me the price up front and stuck to it. Honest and stress-free.”


Suresh Iyer
“Our boiler gave up on a Sunday morning. They came in one hour and had it running again before lunch. Good Job Daniel!”


Sophie Novak
“We wanted a safety check before moving into an older property. The engineer was thorough and picked up small issues we never would have noticed. Very reassuring to know it’s safe now.”
