Should you use a builder recommended by a friend?

A friend or neighbour recommending a builder feels like a shortcut to a trustworthy tradesperson. After all, someone you know has seen the work first-hand. Personal recommendations are valuable, but they are not enough on their own. Your project, your budget and your expectations may be very different from your friend's.

This guide explains how to use a recommendation wisely, what extra checks to make and when to walk away. For more advice on finding a builder, read our guide to how to find the right builder.

Why recommendations work

A recommendation from someone you trust is often more useful than an anonymous online review. You can ask detailed questions, visit the finished work and get a sense of how the builder behaves on site.

Recommendations also reduce the risk of cowboy builders. Cowboy builders rarely survive on repeat business or referrals. A builder with a string of happy local customers has a reputation to protect.

Why recommendations are not enough

A recommendation is a single data point. It tells you about one project, on one property, at one point in time. It does not tell you:

• Whether the builder has experience with your type of project.
• Whether their price is competitive.
• Whether their insurance and qualifications are up to date.
• Whether they are currently overbooked or understaffed.
• Whether their business has changed since your friend used them.

A builder who did a brilliant kitchen extension may not be the right choice for a complex loft conversion or a full renovation.

Questions to ask your friend

Before you contact the recommended builder, ask your friend detailed questions:

• What work did the builder do?
• Did the project finish on time?
• Did the price match the quote?
• How did the builder communicate?
• Were there any problems and how were they resolved?
• Was the site left tidy?
• Did the builder use quality materials?
• Would they hire the builder again?
• Did they have a written contract?

The answers give you context. A builder who finished late but communicated well may still be a good choice. A builder who was cheap but left a mess may not suit you.

Visit the finished work if you can

Photos are useful, but visiting the project in person is much better. Look at the quality of finishing, the alignment of doors and windows, the neatness of tiling and the overall feel of the space. Ask your friend to point out any snags that were fixed and any that were not.

Online reviews and recommendations

A personal recommendation should sit alongside other sources of information, not replace them. Online reviews can give you a wider picture of how a builder behaves across many projects. Look at detailed reviews rather than star ratings alone. A builder with consistent praise for communication and finishing is usually a safer bet than one with inflated scores but vague comments.

Be cautious of review profiles that look too good to be true. A large number of reviews posted in a short period, repetitive wording or a lack of detail can be warning signs. Cross-check reviews on more than one platform.

Do your own checks

Even with a strong recommendation, you should carry out the same checks you would for any builder. These include:

• Checking references from other recent customers.
• Verifying insurance cover.
• Confirming qualifications and trade body membership.
• Checking Companies House records if they trade through a limited company.
• Looking at online reviews on platforms such as Checkatrade or Which? Trusted Traders.

Our guide to checking a builder's insurance and qualifications covers these checks in detail.

Get multiple quotes

A recommendation does not mean you should skip the quoting process. Get at least three itemised quotes for your project. This helps you confirm whether the recommended builder's price is fair and may reveal differences in scope or specification.

Our guide to how to compare builder quotes explains how to evaluate quotes fairly.

Watch out for the "friend of a friend" trap

Be cautious when the recommendation is distant. A friend of a friend, a colleague's cousin or a social media contact is not the same as a recommendation from someone whose work you can see.

Also be wary if the recommender has a financial interest. Some builders offer referral fees, which can distort recommendations.

Check the builder's current situation

Businesses change. A builder who was excellent two years ago may now be overstretched, have lost key staff or changed their pricing. Ask about their current workload, team and availability.

A builder who is too busy to start for six months may still be worth waiting for. A builder who can start tomorrow with no references may be a warning sign.

Match the builder to the project

Make sure the builder has relevant experience. A specialist in small renovations may struggle with a large extension. A builder who usually works on new builds may not understand the quirks of a Victorian property.

Ask to see examples of similar work. If the builder cannot show you comparable projects, the recommendation may not translate to your job.

Do not let friendship pressure you

If a friend recommends their brother, cousin or neighbour, there can be social pressure to hire them. Do not let that pressure override your checks. A bad building project can damage both your home and your friendship.

Be polite but firm. Explain that you are getting several quotes and carrying out your usual checks. A professional builder will respect that.

What if the recommended builder does not feel right?

Trust your instincts. If the builder is evasive, late to meetings, vague about price or reluctant to provide a written contract, walk away. A friend's good experience does not guarantee yours.

Put everything in writing

Even if you know the builder through a friend, you still need a written contract, a clear scope of work and a fair payment schedule. Verbal agreements cause disputes, and friendship makes those disputes harder to resolve.

Read our guide on what to include in a building contract for a checklist of essential clauses.

Keeping the relationship professional

When you hire a builder through a personal connection, it is tempting to treat the arrangement informally. Resist this. Friendly introductions should lead to professional working relationships, not vague agreements. Clear communication, written records and agreed deadlines protect both you and the person who made the introduction. If problems do arise, address them directly with the builder rather than complaining to your friend. That keeps the recommendation separate from any dispute and makes it easier to resolve issues professionally.

Final thoughts

A builder recommended by a friend is a strong starting point, but it is only a starting point. Visit the work, ask detailed questions, get multiple quotes and do your own checks. The best builders will welcome your diligence.
