Planning a home improvement project?

Whether you’re building an extension, renovating your kitchen or carrying out structural work, choosing the right builder is one of the most important decisions you’ll make. The wrong choice could lead to delays, poor workmanship and unexpected costs.

So, how do you choose a trustworthy builder?

The best builders have genuine customer reviews, appropriate insurance, clear written quotes, relevant experience and a proven track record of completing projects successfully.

Here’s everything you should check before signing a contract.


1. Read genuine customer reviews

Start by checking independent reviews.

Look for feedback that mentions:

  • Quality of workmanship
  • Communication
  • Reliability
  • Tidiness
  • Whether the project stayed on budget

A large number of positive, detailed reviews is usually a good sign.


2. Ask to see previous work

A reputable builder should be happy to show examples of completed projects.

Ask to see:

  • Photos
  • Before-and-after images
  • Similar projects
  • References from previous clients

If possible, visit a completed project in person.


3. Get at least three written quotes

Never accept the first quote you receive.

Comparing several builders helps you understand:

  • Fair pricing
  • What’s included
  • Project timescales
  • Different approaches

The cheapest quote isn’t always the best value.


4. Make sure the quote is detailed

A professional quote should clearly explain:

  • Labour costs
  • Materials
  • Payment schedule
  • Timescale
  • VAT
  • What’s excluded

A vague estimate can easily lead to disputes later.


5. Check insurance

Ask whether the builder has:

  • Public liability insurance
  • Employer’s liability insurance (if applicable)
  • Contractor’s insurance

This helps protect both you and the builder if something goes wrong.


6. Ask about qualifications and experience

Experience matters—especially for larger projects.

Choose someone who regularly completes work similar to yours, whether that’s:

  • Extensions
  • Loft conversions
  • Renovations
  • Bricklaying
  • Structural alterations

7. Avoid large upfront payments

Be cautious if a builder asks for most of the money before work begins.

A typical payment schedule is based on project milestones rather than paying everything in advance.

Always ask for receipts and keep records of payments.


8. Check who’s doing the work

Ask whether:

  • The builder completes the work personally.
  • Subcontractors will be used.
  • Specialist trades will be brought in.

Knowing who will actually be on-site can help avoid misunderstandings.


9. Get everything in writing

Before work starts, make sure you have written confirmation of:

  • Total price
  • Scope of work
  • Start date
  • Completion date
  • Payment schedule
  • Guarantees

Written agreements protect both parties.


10. Don’t feel pressured

Be cautious if a builder says:

  • “Today’s the last day for this price.”
  • “I’ve got spare materials.”
  • “I need a cash deposit now.”

Reputable builders rarely use high-pressure sales tactics.

Take your time before making a decision.


11. Check communication

A trustworthy builder should:

✔ Respond promptly

✔ Answer questions clearly

✔ Explain the process

✔ Be honest about timescales

Good communication is often a sign of a well-managed business.


12. Trust your instincts

If something doesn’t feel right, don’t ignore it.

Warning signs may include:

  • Refusing to provide references
  • Unclear pricing
  • Poor communication
  • No written quote
  • Requests for large cash payments

It’s usually better to keep looking than rush into hiring the wrong contractor.


Common mistakes to avoid

Many homeowners regret:

  • Choosing the cheapest quote without comparing quality.
  • Paying large deposits upfront.
  • Not checking reviews.
  • Accepting verbal agreements.
  • Failing to ask what’s included in the quote.

Avoiding these mistakes can save both time and money.


Frequently Asked Questions

Should I always get three quotes?

Yes.

Comparing several detailed quotes gives you a better understanding of fair pricing and helps you choose the builder offering the best value.

Is the cheapest builder the best choice?

Not necessarily.

Very low quotes can sometimes mean corners are being cut or important work has been left out.

Should a builder provide a written quote?

Absolutely.

A written quote helps prevent misunderstandings and clearly sets out what’s included in the project.

How much deposit should I pay?

It depends on the project, but you should be cautious about paying a large amount upfront. Agreeing staged payments linked to completed work is often a safer approach.


Final thoughts

Choosing a trustworthy builder takes a little extra time, but it’s one of the best ways to protect your home and your budget.

By comparing quotes, checking reviews, confirming insurance and insisting on a clear written agreement, you’ll greatly reduce the risk of unexpected problems and have a much better chance of a successful project.
