The short answer: shortlist evidence, not the lowest headline total
A useful shortlist compares the contracting entity, work relevant to your property type, the people who will manage the site, the completeness of the scope, the payment and variation controls, and what happens at handover. A polished proposal or large photo gallery answers only part of that review.
Use the same floor plan, photos, priorities and scope brief for each candidate. If every company is pricing a different interpretation, the totals are not yet a reliable comparison.
Treat registrations as entry checks, not quality guarantees
For an HDB flat, HDB tells homeowners to engage a contractor listed in its Directory of Renovation Contractors for renovation work. HDB also states that a DRC listing means the contractor is aware of HDB requirements; it does not endorse or guarantee the quality of the contractor's work.
Verify the current listing against the legal entity that will sign the contract. For other work, check the registrations, professional appointments or trade qualifications that actually apply to the proposed scope rather than relying on a logo shown without context.
Match completed evidence to the project you are planning
Ask for recent examples that resemble the property type and difficult parts of your scope: an older landed house, a condo under management rules, wet-area replacement, structural coordination, occupied work or commercial handover. One attractive room does not demonstrate every capability.
Ask who led those projects, which parts were self-performed or subcontracted, and who will be accountable on your site. References or site visits should be arranged only with the previous client's permission.
Compare the scope line by line before comparing price
Mark quantities, specifications, preparation, protection, disposal, testing, making good, professional fees, submissions, owner-supplied items and exclusions. Identify allowances and site conditions that cannot yet be priced firmly.
A lower total can be legitimate, but it should be explainable through scope, specification or method. Unstated work is not automatically included, and a vague lump sum makes later changes harder to assess.
Use clear contract, payment and variation controls
CASE's CaseTrust renovation scheme offers a useful benchmark for accredited businesses: a standard renovation contract, payment by agreed milestones, transparent pricing, written agreement for variations, warranty terms and prepayment protection. These protections should not be assumed for a business that is not currently accredited.
Whatever contractor you consider, ask for a written programme, milestone definitions, variation procedure, warranty terms, termination position and dispute route. Confirm that the company name and payment instructions match the contracting entity before transferring money.
Interview the delivery team, not only the salesperson
Ask who prepares drawings, coordinates trades, checks dimensions, reports progress, records concealed work, obtains approvals where applicable and closes defects. Find out how often the responsible person attends site and how decisions are documented.
A credible team should be willing to identify what is still unknown. Promises that structural feasibility, authority approval, hidden conditions or completion dates are certain before the required checks deserve closer scrutiny.
Use a final shortlist sheet before appointment
For each candidate, record the legal entity, current relevant registrations, comparable projects, named project lead, scope gaps, provisional sums, exclusions, programme, payment milestones, variation method, warranty and outstanding questions.
Choose only after the important differences are visible. The aim is not to eliminate every project risk; it is to select a team whose scope, controls and evidence make those risks easier to manage openly.
Check the current official guidance against the proposal.
These links support the planning points explained above. Requirements can change and the official pages should be checked again when the project scope is developed.
Use the note as a starting point.
Send the floor plan, site photos and rough scope for an initial project review.
