How to choose a builder in North London
Choosing the right builder is the single biggest factor in whether your project is a pleasure or a nightmare. Here is a practical checklist for homeowners in North London and Hertfordshire.
What to check
- A fixed, itemised quotation, not a vague one-line estimate that can creep up.
- Public liability insurance and, for new builds, a structural warranty.
- Recent local projects and references you can actually speak to.
- A written contract and a clear payment schedule tied to stages.
- Whether they handle design, planning and building control, or expect you to.
Red flags to avoid
- A large deposit up front with no clear stage payments.
- Cash-only, no contract, no paperwork.
- A price far below everyone else (something is usually missing from the scope).
- No fixed timeline or programme.
- Reluctance to put anything in writing.
Why itemised pricing matters
An itemised quotation, where every trade is priced line by line, tells you exactly what you are paying for and makes it obvious if something has been left out. That is exactly what our instant estimator produces, and what your fixed quotation looks like after a site visit.
Frequently asked questions
How do I know a builder is insured?+
Ask to see their public liability insurance certificate, and for new builds, confirm the structural warranty provider. A reputable builder will share these without hesitation.
Should I pay a deposit?+
A modest deposit or a payment for design and materials is normal, but avoid large up-front sums. Payments should be tied to completed stages.
How many quotes should I get?+
Two or three is sensible. Compare scope, not just price, because the cheapest quote often leaves things out that appear as extras later.
