For Self-Builders
Self-Build Support — We Handle the Hard Parts So You Can Build Your Dream.
Foundations. Structural frame. Roofing. M&E. The elements of a self-build that need certified tradespeople, Building Control sign-off, and a contractor who will still be there when the inspector arrives.
The Problem Self-Builders Face
Self-building is one of the most rewarding things you can do — and one of the easiest ways to end up in serious financial trouble. The broken construction industry targets self-builders specifically: low quotes to win work, deposits taken, contractors who disappear, and structural elements that fail inspection. By the time the problems surface, you are months behind and thousands over budget with no recourse.
RCB gives self-builders a contractor they can rely on for the elements that cannot go wrong.
What RCB Handles for Self-Builders
You manage the project. You make the design decisions. We handle the specialist elements that require certified contractors, Building Control inspections, and people who know what they are doing when the inspector is watching.

- Steel frame erection and structural masonry to Building Regulations
- Structural alterations, beam installations, and load path management
- Building Control inspections coordinated and passed — not just hoped for
Roofing & Weathertight Shell
- Pitched and flat roof structures, including warm roof and cold roof systems
- Roof coverings, flashings, and drainage to NHBC and Building Regs standards
- Windows and external doors supplied and installed to your specification
- Weathertight shell signed off before your interior trades commence
Mechanical & Electrical
- First fix electrical installation with appropriate certification (Part P)
- Plumbing and heating first fix including underfloor heating systems
- MVHR, solar PV, and heat pump installations coordinated with your design
- All M&E works tested, certified, and handed over with full documentation
Building Control & Sign-Off
- Building Control applications submitted and managed from start to finish
- Structural engineer and approved inspector coordination included
- All staged inspections attended and signed off before moving to the next phase
- Completion certificate issued — without it, your self-build mortgage does not release
How We Work With Self-Builders
We fit into your self-build — not the other way around. You keep control. We deliver the specialist elements on a fixed price, on programme, and with every sign-off you need.
Understand Your Self-Build Vision
We review your plans, your planning consent, and your structural engineer's specification. We identify the elements that need a specialist contractor and give you a clear picture of what we can take off your plate.
Fixed-Price Scope Agreed
Foundations, structural frame, roofing, and M&E scoped in detail and priced with full itemisation. You know exactly what you are paying for each element — and what it excludes. No grey areas.
Programme Tied to Your Build Sequence
Our works are programmed around your self-build sequence. We do not arrive before the site is ready or leave gaps that stall your other trades. Your programme is our programme.
Works Signed Off as We Go
Every stage inspection is attended and signed off before the next phase begins. Building Control, structural sign-off, and M&E certification all happen in sequence — so you are never building on unverified work.
Why Self-Builders Choose RCB
Accreditations are your protection. CHAS, Constructionline, FMB, and TrustMark mean your contractor has been vetted — not just recommended by someone who had a good experience once.
Independently Verified
All 114 reviews on Checkatrade are from verified clients. Our 9.96/10 rating is independently audited — not curated. When you are investing your savings in a self-build, the track record of your contractor matters as much as their quote.
Self-Build FAQs
Can I manage some of the work myself and use you for the specialist elements?
Absolutely — and this is the model we work best under with self-builders. You take on the elements you are comfortable managing: landscaping, interior fit-out, decoration. We handle the elements that require Building Control sign-off, certified tradespeople, or structural engineering input. We do not need to be your only contractor — we just need to be the right one for the hard parts.
Do you work on plots or only existing properties?
Both. We work on new-build plots from groundworks up, and on conversion and renovation projects where self-builders are taking on an existing structure. For plot builds, we can take you from groundworks to weathertight shell. For conversions, we handle the structural and M&E elements so you can focus on the finishes.
Can you help with the Building Control application?
Yes. We can advise on the application process, submit Building Notice applications for straightforward works, and coordinate with an approved inspector for more complex projects. All our works are carried out to the standard required for Building Control sign-off — and we attend every inspection.
What is the minimum scope you will take on for a self-builder?
We do not have a rigid minimum — but we are most useful when the scope is substantial enough to justify a formal contract and programme. If you need foundations, a structural frame, a roof, or a full M&E installation, we are a good fit. For very small individual tasks, a specialist subcontractor may serve you better.
