Searching for the Best Builder in Surrey?
Our Complete guide on exactly what to look for when selecting your build partner
Our Guide to Finding a Trusted Builder in Surrey or Beyond
When you begin an extension or new-build project, you may have little experience of construction — and for many homeowners, this will be the first major project since purchasing their home. It might also be one of the largest financial commitments you will make. Choosing the right builder is therefore more than just a practical decision: it influences your experience, your budget, your timescales and, ultimately, your peace of mind. With the right Surrey builder, your project becomes structured, transparent, and genuinely satisfying. With the wrong team, it can become stressful and fraught with uncertainty. Trust is the foundation of any successful build.
Our philosophy is rooted in real-world experience. Over twenty years ago, our founder, Phil West, found himself in exactly the same position many homeowners face today — navigating unclear communication, inconsistent workmanship and an overwhelming lack of guidance when selecting a builder for his own home. That experience inspired him to establish Complete Building Solutions — a company built on clarity, high standards and genuine client care. While we naturally set our own bar high as the best builder in Surrey, we also respect and support fellow professionals who share our commitment to quality, transparency and integrity.
When a project isn’t the right fit for us, we are often asked how to find a firm that upholds the same standards for more modest work — and every homeowner deserves to feel confident, informed and protected. So, our team created this guide to outline the ideal standards for selecting a builder in Surrey or anywhere across the UK.
1. Verified Credentials & Industry-Recognised Standards
When evaluating builders in Surrey, start by asking for credentials, qualifications and proof of insurance. A reputable builder should offer transparency from the outset, a sign of professionalism, and accountability.
Look for:
valid public liability and employer’s liability insurance
recognised trade memberships or accreditations
evidence of regulated training or certifications
These indicators show that the builder takes compliance and safety seriously — a common trait among Surrey’s most respected building companies.
2. Detailed, Transparent Quotations
Clear, detailed quotations are essential. A reliable builder will provide a written quote that comprehensively outlines:
labour costs
material costs
project phases and timelines
what is included and what is excluded
contingencies or provisional sums
Builders truly operating at the level expected of the best builders in Surrey price responsibly — not cheaply, not vaguely, but realistically. The cheapest quote can often become the most expensive as the project progresses and generates a lot of stress and poor results. Responsible, transparent quoting is absolutely vital to project success and peace of mind.
3. A Written Contract That Reflects Industry Standards
Any professional builder should supply a clear, written contract before work starts. This contract should cover:
the full scope of works
the agreed project programme
payment terms
procedures for variations
warranties and compliance commitments
dispute-resolution mechanisms
A proper contract protects both client and builder, setting clear expectations from the outset.
4. Sensible Payment Terms — No Large Upfront Payments
Payment structure is a clear sign of a builder’s integrity.
At Complete Building Solutions, we do not request upfront payments. Instead, we invoice monthly for completed work, with the value of work assessed by a Quantity Surveyor. As an established and financially robust company, this structure delivers clarity, security, and transparency for our clients throughout the project.
While smaller firms may request modest deposits, significant upfront payments are a risk — and should be avoided wherever possible. For those seeking the best builder in Surrey, sensible, staged payment terms are a major indicator of reliability.
5. Proven Experience — Especially With Projects Like Yours
The right builder for your Surrey home is one who has completed projects similar in scope. Ask for:
examples of comparable renovations, extensions or structural work
project photo galleries
client testimonials or references you can contact directly
opportunities to inspect completed work where possible
Quality workmanship, consistent finishes and attention to detail are the hallmarks of a true Surrey building specialist.
6. A Stable, Skilled Team — Not Just Ad-Hoc Contractors
Who actually builds your project matters.
A professional builder should use a reliable mix of direct employees and long-standing specialist subcontractors. When a builder relies solely on ad-hoc contractors, the project becomes vulnerable to delays, inconsistencies, and lack of accountability.
At Complete Building Solutions, we maintain a dedicated core team supported by expert tradespeople we have worked with over the years, ensuring consistency, reliability and high standards at every stage.
Ask potential builders:
whether they employ their core team directly
how long subcontractors have worked with them
what happens if a subcontractor becomes unavailable
This insight can reveal a lot about how smoothly your project may proceed.
7. Familiarity With Surrey Building Control & Local Regulations
Each Surrey borough has its own building-control procedures and regulations. A builder who is familiar with your local authority can guide your project smoothly through compliance, inspections and approvals.
If you live in Surrey, it’s worth checking whether your builder has previously completed work under your borough’s building-control regime — this helps reduce the risk of delays or compliance issues
At Complete Building Solutions, we have established strong working relationships with multiple Surrey building-control departments and are proud to be recommended by Woking Borough Council as a partner firm.
8. Clear Communication & Professional Conduct From Day One
Good communication is one of the most reliable early indicators of how a build will run.
Signs of a professional Surrey builder include:
prompt, clear responses
considered questions and constructive feedback
realistic timelines
respect, punctuality and transparency during site visits
These characteristics often reflect how a builder will behave throughout your project.
9. Fair Pricing That Reflects Real Value — Not Just the Cheapest Option
When comparing quotes across Surrey, remember:
The cheapest builder is rarely the best builder.
A trustworthy builder will price realistically, allocate appropriate labour and materials, avoid shortcuts and communicate honestly about potential risks or variations. Investing in quality often saves money, time and stress in the long term.
Why These Standards Matter When Searching for the Best Builder in Surrey
Choosing a builder means selecting who will work in your home, manage your investment and shape the experience of your build. Surrey is home to many excellent builders who work with integrity, care and craftsmanship. We believe in recognising and supporting colleagues who adopt the same high standards we uphold across the UK.
At Complete Building Solutions, these principles guide every project we undertake — but above all, they reflect how we believe the construction industry should operate: responsibly, transparently and with respect for homeowners.
Your Final Checklist Before You Commit

✔ They avoid large upfront payments
✔ They have proven experience with similar Surrey projects
✔ Their team is stable, skilled and dependable
✔ They understand and navigate local Surrey building-control regulations
✔ Their communication feels clear, steady and professional

If so, you’re well on your way to choosing a builder you can trust — and potentially one of the best builders in Surrey, or beyond, for your project.
