Choosing the right contractor is one of the biggest decisions on a refurbishment project. In the 2026 UK market, clients are still dealing with cost pressure, labour shortages, long material lead times and a construction sector that has become more cautious. A low quote can look attractive, but if the scope is unclear it can quickly become the most expensive option.

Start with the scope, not the price

Before comparing contractors, make sure each company is pricing the same information. A proper quote should describe what is included, what is excluded, what is assumed, and what will be treated as a variation. This matters especially on existing buildings, where hidden damp, defective floors, old wiring, roof leaks and drainage issues may not be visible until works begin.

When one quote is much cheaper than the others, it is often because something has not been allowed for. That may be labour time, waste removal, access, temporary protection, Building Control requirements, fire upgrades, structural works, finishes, or testing and certification.

What to check before appointment

• Relevant experience with similar refurbishment or commercial fit-out projects.
• A clear written scope, including materials, workmanship standards, programme assumptions and exclusions.
• Insurance, company details, and who will actually manage the project day to day.
• How the contractor handles variations, approvals, delays and unexpected discoveries.
• Whether they understand Building Control, structural coordination, fire safety, M&E services and sequencing.

Ask how problems will be managed

Every serious refurbishment has unknowns. The important question is not whether a contractor can promise there will be no issues; it is whether they have a process for dealing with them properly. For example, if damp is uncovered behind finishes, if floor joists are moving, or if a roof has hidden leaks, the contractor should be able to stop, record the issue, advise the client, agree the solution and proceed with written approval.

Look for technical responsibility

Many disputes happen because no one is clearly responsible for coordination. A good contractor should understand how the builder, electrician, plumber, structural engineer, architect and Building Control process fit together. On larger or more complex projects, a project manager or design-led contractor can reduce risk by coordinating drawings, sequencing, procurement and site decisions.

Final checklist before you sign

• Confirm the scope and drawings being priced.
• Confirm VAT, payment stages and variation procedure.
• Confirm start date, target duration and working hours.
• Confirm waste, access, welfare, parking and neighbour considerations.
• Confirm certificates expected at completion.
