The Complete Guide to Hiring a Builder in Dorset & Hampshire

Hiring a builder is one of the biggest financial decisions most homeowners will make outside of buying their house. Get it right and you end up with a quality build, delivered on time and on budget. Get it wrong and you're looking at unfinished work, spiralling costs, and months of stress. Having worked across Christchurch, Bournemouth, Poole, and into Hampshire for years, I've seen both outcomes — and the difference almost always comes down to how well the homeowner vetted their builder before signing anything.

This is the guide I wish every homeowner would read before they hire anyone. It covers where to find good builders, how to spot the dodgy ones, what questions to ask, and how to protect yourself with a proper contract and payment schedule.

Where to Find Reliable Builders

Personal Recommendations

Still the best way to find a builder. If a friend, family member, or neighbour has had work done recently and they're happy with the result, that builder goes to the top of your list. Ask them not just whether the work was good, but whether the builder was easy to communicate with, whether they stuck to the quoted price, and whether they'd use them again.

In a town like Christchurch, word of mouth travels fast — both good and bad. Builders who consistently deliver quality work get recommended constantly. The ones who don't, don't last long.

Trade Bodies and Associations

Membership of recognised trade bodies is a good starting filter:

• Federation of Master Builders (FMB): Members are vetted, independently inspected, and must carry appropriate insurance. The FMB also offers a warranty scheme.

• National Federation of Builders (NFB): Similar vetting process with a focus on professional standards.

• Guild of Builders and Contractors: Members undergo regular inspections of live projects.

• TrustMark: A government-endorsed quality scheme. TrustMark-registered businesses meet specific standards and offer deposit protection.

Trade body membership doesn't guarantee a perfect builder, but it does mean they've been vetted, they carry insurance, and there's a complaints process if things go wrong.

Online Platforms

Checkatrade:Useful for reading recent reviews, but remember that builders pay to be listed. Look at the volume and recency of reviews, not just the overall score. A builder with 200 reviews averaging 9.5/10 is more reliable than one with 5 reviews at 10/10.

MyBuilder:Homeowners post jobs and builders respond with interest. The review system is solid because only people who've actually hired the builder can leave reviews.

Local Facebook groups:Christchurch and Dorset community groups are full of recommendations. Search for previous posts asking for builder recommendations — you'll find dozens.

Driving Around

This sounds old-fashioned but it works. If you see building work happening in your area, make a note of the company name on the van or hoarding. If the site looks tidy and well-organised, that tells you something about how they work. You could even knock on the door and ask the homeowner how it's going — most people are happy to chat about their build.

Red Flags: Warning Signs to Watch For

These are the warning signs that should make you think twice — or walk away entirely:

1. No Written Quote

If a builder gives you a price verbally or scribbles it on the back of an envelope, that's not a quote. A professional builder provides a detailed written quote with an itemised breakdown, clear scope of work, and terms. Verbal agreements are worth the paper they're printed on — which is none.

2. Demands for Large Upfront Payment

Any builder asking for 25%, 30%, or more before they've started work is either cash-strapped or planning to disappear. A reputable builder has sufficient cash flow to start a project with a modest deposit (5-10%). If they need your money to buy materials, ask yourself where the money from their last job went.

3. Cash-Only Payment

There's nothing illegal about paying cash, but a builder who insists on it — especially without providing receipts or invoices — is almost certainly not declaring the income. If they're happy to cut corners with HMRC, they'll cut corners on your build. Always pay by bank transfer and keep records.

4. Pressure to Start Immediately

"I've had a cancellation and can start Monday if you sign today" is a classic pressure tactic. Good builders are busy. They have work lined up. A builder with no diary commitments either isn't getting repeat business (red flag) or is using high-pressure sales (also a red flag). Take your time, do your due diligence, and don't let urgency override good judgement.

5. No Insurance Documentation

Every builder should carry public liability insurance (minimum £2 million) and employer's liability insurance if they have employees. Ask to see the certificates and check the dates. If they can't or won't provide them, move on. Without insurance, you could be liable if a worker is injured on your property or if the work causes damage to a neighbour's property.

6. Reluctance to Put Things in Writing

"Don't worry, we'll sort it out as we go" is the precursor to disputes. Everything should be in writing: the quote, the scope, the payment schedule, the timeline, and any changes made during the project.

7. No Fixed Business Address

A builder who operates solely from a mobile number with no verifiable business address, no Companies House registration, and no business website is difficult to hold accountable if something goes wrong. Check Companies House for their registration, look them up on Google Maps, and verify they actually exist as a business.

8. Badmouthing Other Builders

A professional builder talks about their own work, not someone else's. If a builder spends the consultation criticising competitors rather than discussing your project, that tells you more about their character than their competence.

Green Flags: Signs You've Found a Good One

These are the positive indicators that suggest you're dealing with a professional:

• Detailed, itemised quote that clearly sets out what's included and excluded

• Happy to provide references and encourages you to visit previous jobs or speak to past clients

• Proof of insurance provided without you having to chase it

• Trade body membership (FMB, TrustMark, or equivalent)

• Clear timeline with realistic start and completion dates

• Professional communication — returns calls and emails promptly, explains things clearly

• Tidy previous work — if you visit a current or completed site, it's clean and well-finished

• Honest about limitations — a good builder tells you what they can't do as readily as what they can

• Suggests a written contract before you even ask for one

• Manages expectations — tells you about potential issues upfront rather than pretending everything will be straightforward

15 Essential Questions to Ask Before Hiring

Before you commit to a builder, get satisfactory answers to all of these:

How to Verify Credentials

Don't take anyone's word for it. Verify independently:

• Companies House: Search for the company name at companieshouse.gov.uk. Check when they were incorporated, who the directors are, and whether accounts are filed. A company that's been trading for 10 years is a very different proposition from one incorporated 6 months ago.

• Trade body websites: Search the FMB, TrustMark, or other claimed membership directly on those organisations' websites. Don't just take a logo on a van as proof.

• Insurance: Ask for the actual certificate, not just a claim of being insured. Note the policy number, the insurer, and the expiry date. For larger projects, you can ask them to add you as an interested party on the policy.

• VAT registration: If the builder is VAT-registered, their VAT number should be on their invoices. You can verify this at gov.uk. Note: smaller builders may legitimately not be VAT-registered if their turnover is below the threshold (currently £90,000).

• Reviews: Check multiple platforms — Checkatrade, Google, MyBuilder, Facebook. Look for patterns. One bad review among dozens of good ones is normal. Multiple reviews mentioning the same problems (poor communication, abandoned work, price increases) is a pattern.

• Previous clients: Actually call or visit the references they provide. Ask the homeowner directly: "Would you hire them again?" That one question tells you everything.

What a Good Contract Looks Like

Never start a building project without a written contract. For domestic projects, the JCT (Joint Contracts Tribunal) Homeowner contract is widely used and well understood. It covers:

• Scope of work: Exactly what's being built, with reference to the approved drawings and specification

• Contract sum: The agreed price, stated as fixed price or subject to variations

• Start and completion dates: With provisions for extensions of time in specific circumstances (bad weather, late material deliveries, etc.)

• Payment schedule: When payments are due and what triggers each stage payment

• Variations procedure: How changes to the scope are agreed and priced

• Insurance requirements: What insurance the builder must maintain throughout the project

• Defects liability period: Typically 6-12 months after completion, during which the builder must return to fix any defects at their own cost

• Dispute resolution: How disagreements are handled (mediation, adjudication, etc.)

• Termination provisions: Under what circumstances either party can end the contract

A builder who's reluctant to sign a contract is a builder you shouldn't hire. A proper contract protects both parties equally. It gives the builder certainty that they'll be paid for completed work, and it gives you certainty about what you're getting, when, and for how much.

Payment Schedule Advice

This is worth repeating because it's where so many homeowners lose money:

• Deposit: 5-10% maximum. Anything more is excessive for domestic projects.

• Stage payments: Tied to completed and inspected milestones, not calendar dates. You pay when foundations are done, when the structure is watertight, when first fix is complete — not every two weeks regardless of progress.

• Retention: Hold back 5% of the total for 4-8 weeks after completion to cover snagging. This is standard practice and any reputable builder will accept it.

• Never pay ahead of the work. If a builder asks for payment for work not yet completed, that's a warning sign.

• Keep records. Photograph completed stages before making payments. Save all invoices and bank transfer confirmations.

What If Things Go Wrong?

Despite best efforts, sometimes things don't go to plan. Here's what to do:

The best protection is prevention. Do your homework upfront, get a proper contract, use a stage payment schedule with retention, and maintain open communication throughout the project. The vast majority of building projects in Dorset and Hampshire go smoothly when both parties are professional and transparent from the start.

Final Thought

Hiring a builder shouldn't feel like a gamble. If you do the research, ask the right questions, verify the credentials, and set up a proper contract, you'll dramatically reduce the risk of problems. The best builders welcome scrutiny — they know their work stands up to it, and they'd rather work with informed clients who understand the process.
