See the full verification checklist for Call Si Ltd →Active incorporated business
Call Si Ltd is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 4 years on the register also points to an established business rather than a brand-new one.

Highlights
“Highly recommend if you want your plumbing fixed with skill! Si was super efficient, clearly knows his stuff, zero stress, rating 10/10. I am grateful and kinda hoping something else breaks so I have an excuse to call again.”
“Si was great to have for the job - he came round and inspected the work to be done without charge, then got me booked in quickly and stuck to that date and time. The work was carried out as expected and he left everything clean and tidy, and also talked through with me what he was doing.”
