What Clients Say
59 five-star reviews. Every single one.
Not a single review below five stars across Google and Bark. Read what homeowners, landlords and developers say about working with Ade and the team.
★★★★★
"If I could I would give Ade 10 stars. I interviewed 5 contractors and was very lucky to have chosen Ade. He has a very positive 'can do' attitude and he and his team go above and beyond to ensure the work is completed to a very high standard. 'Good enough' is not in Ade's vocabulary."
★★★★★
"Bayocorp not only completed our full renovation but were the most communicative, collaborative, trustworthy team - and ultimately cared the most about the outcome. Ade designed a bespoke kitchen that others hadn't even thought of. After completion they sent someone over immediately for any niggles."
★★★★★
"Bayo Corp exceeded all expectations. Ade and his team delivered top-tier craftsmanship, combining style, precision, and a real commitment to doing the job right. If you're looking for a builder who is reliable, solutions-focused, and genuinely passionate about quality - Bayo Corp should be your first call."
How It Works
From first enquiry to handover - six clear steps.
No ambiguity. No chasing. Just a structured process that keeps your project under control from start to finish.
1
Project Review & Scope Alignment
We review your submitted details, clarify the scope, resolve any unknowns, and align expectations so both parties understand the project requirements, costs, and next steps before progressing.
2
Third-Party Approvals & Constraints
We confirm planning permissions, building control requirements, freeholder approvals, and any other external constraints that need to be addressed before the project moves forward.
3
Scope Lock & Specification Sign-Off
We finalise materials, finishes, layouts and technical details - converting all allowances into fixed selections and creating a fully defined, buildable scope.
4
Programme & Delivery Planning
We build the detailed programme, sequencing and delivery strategy - ensuring every trade is in the right place at the right time with the right information.
5
Contract Confirmation & Formal Agreement
We issue clear contract documentation covering responsibilities, timelines, payment structure and deliverables before any work commences on site.
6
Pre-Start Planning & Mobilisation
We confirm logistics, communication protocols, site setup and key contacts - ensuring a smooth, well-organised start to active construction works.
