Hiring a Reliable Builder for Your Project

Why Getting the Right Builder Matters

Few home improvements cause as much worry as choosing someone to work on your property. Whether you are extending a kitchen, converting a loft or repointing a Victorian terrace, the person you appoint will have a direct impact on your budget, your stress levels and the value of your home. The good news is that a little groundwork before you sign anything will save you an enormous amount of trouble later. Most disputes in the building trade come down to the same handful of avoidable problems: vague quotes, missing insurance, and payment arrangements that leave the homeowner exposed.

This guide sets out what to check, what to ask and what to get in writing, so you can appoint a builder with confidence rather than hope.

Start With Recommendations and References

A personal recommendation from a neighbour, friend or colleague is still the single best starting point. Someone who has lived through a project with a builder will tell you things no advert ever will — how tidy they were, whether they turned up when they said they would, and how they handled the inevitable hiccup.

Once you have a shortlist, ask each builder for references from at least two recent jobs, ideally similar in size and type to yours. Then actually contact those people. A few good questions will tell you a great deal:

• Did the builder finish on time, and if not, why?
• Was the final bill close to the original quote?
• How did they handle any problems or changes along the way?
• Would you use them again?

Where possible, ask to view a completed job in person. A quick look at the finish — neat tiling, tidy skirting, clean mortar lines — tells you more about workmanship than any glossy photograph. You can also check whether a trader is a member of a recognised trade association or competent person scheme, which usually requires a minimum standard of work and offers a route to complain if things go wrong.

Insurance and Credentials: Non-Negotiable Checks

Before you go any further, confirm two things: that the builder has public liability insurance and, if they employ anyone, employers' liability insurance. Ask to see current certificates — not a policy from three years ago. If a worker is injured on your property, or a delivery damages your neighbour's car, you want that cover in place.

It is also worth asking about:

• Registration for VAT, if their turnover requires it
• Membership of a trade body or a dispute resolution scheme
• Any qualifications relevant to specialist work, such as gas or electrical
• Confirmation of who will actually be on site — the builder you meet, or a subcontractor?

Never rely on a verbal assurance. A reputable builder will hand over these details without hesitation; reluctance is a warning sign.

Get Everything in a Written Quote

An estimate is a rough guess. A quote is a fixed price for specified work. Make sure you are comparing like for like, and insist that every quote is in writing and itemised. It should cover materials, labour, plant hire, waste removal and VAT.

Watch for these common gaps:

• What is excluded — scaffolding, skips, making good, decoration?
• How long the price is held for, and what triggers an increase
• How variations and unforeseen work will be priced and approved
• Who is responsible for building regulations approval and any required certificates
• Start date, working hours and expected completion

If a price seems far below the others, ask why. Cheap quotes often hide extras that appear halfway through, when you have little room to negotiate.

Put a Proper Contract in Place

A written contract protects both of you. It does not need to be long, but it should be clear. Set out the scope of work, the agreed price, the payment schedule, the timescales and how disputes will be handled. If your builder belongs to a trade association, they may offer a standard contract you can both use.

Read it before you sign, and check that the description of work matches the quote exactly. Anything agreed verbally on site should be confirmed in writing — a short email is fine. Keep a folder with the contract, quotes, drawings, invoices and any change notes. If a disagreement ever arises, that paperwork is worth its weight in gold.

Agree a Sensible Payment Schedule

Never pay the full amount up front, and be wary of anyone who asks for a large cash deposit before work begins. A fair arrangement ties payments to progress:

• A modest deposit to secure materials and a start date
• Stage payments as defined milestones are completed
• A retention — typically 5% — held back for a set period after completion to cover snagging

Pay by bank transfer or card where possible, so there is a clear record. Get a receipt or invoice for every payment, and do not pay for work that has not been done. If the builder runs short of cash mid-project, that is their problem to solve — not a reason for you to advance more money.

Managing the Project Day to Day

A good working relationship goes a long way. Agree a single point of contact, keep decisions timely, and raise concerns early rather than letting them fester. Take dated photographs as work progresses, especially of anything that will be covered up later, such as pipework or insulation.

Finally, trust your instincts. If a builder is evasive, pressures you to pay quickly, or cannot produce paperwork, walk away — there is always another tradesperson. Taking a week to check references and sign a proper contract is a small price for peace of mind on a project that will shape your home for years to come.
