How to Choose a Healthcare Refurbishment Contractor: The Questions That Matter

A generalist building contractor can deliver excellent commercial fit-out work and still be the wrong choice for a GP surgery or dental practice refurbishment. The gap is not workmanship — it is clinical governance knowledge. A contractor who has never coordinated a decontamination room workflow, never sequenced work around a live patient list, and never dealt with an ICB or CQC registration deadline will make decisions that look reasonable on site and turn out to be compliance failures once clinical use begins.

The cost of choosing the wrong contractor rarely shows up as an overspend during the build. It shows up afterward, as remedial works to fix a decontamination room layout, a delayed CQC registration because building certificates were not collected in the right sequence, or a programme that assumed the practice could simply close for a few weeks.

Any refurbishment involving more than one contractor requires the client to appoint a Principal Designer and Principal Contractor under CDM 2015. UK contractor pre-qualification schemes such as CHAS, Constructionline, and SafeContractor are the standard way to verify a contractor's health and safety competence before tender. For projects of this scale, JCT Minor Works and JCT Intermediate Building Contracts are the most commonly used standard contract forms.

Why Generalist Contractors Struggle with Clinical Refurbishment

A commercial office fit-out and a GP surgery refurbishment can look superficially similar on a floor plan — partitions, ceilings, flooring, power and data. The difference is in the rooms that are not obviously "special" until something goes wrong: a consulting room without a compliant wash-hand basin position, a decontamination room designed without a one-way workflow, or a corridor width that fails Part M accessibility requirements. A contractor who has only ever built offices has no reason to know these standards exist, let alone how to meet them.

What Should You Ask Before Shortlisting a Contractor?

1. Ask for named references from GP practices or dental surgeries specifically — not "healthcare" in general, and not from more than two years ago
2. Ask the contractor to describe how they would sequence a decontamination room build, or how they would approach X-ray room shielding — if they cannot answer specifically, they have not done this work before
3. Ask for evidence of CDM competency — a Principal Contractor appointment history, not just a generic health and safety policy
4. Confirm current insurance levels, including public liability and, where design input is involved, professional indemnity cover
5. Ask for a draft programme that explicitly addresses working around a live, occupied clinical building — a generic Gantt chart with no phasing logic is a warning sign

What Contract Form Should You Use?

• JCT Minor Works Building Contract — suited to smaller, simpler refurbishment projects with a single contractor and limited design complexity
• JCT Intermediate Building Contract — better suited to mid-scale, phased refurbishments involving multiple trades and a more detailed specification
• Design and Build vs traditional (architect-led) procurement — Design and Build places more risk and design responsibility with the contractor; traditional procurement keeps the practice's own designer in control of the specification throughout

What Are the Red Flags During Tender?

• A quote significantly below every other bid with no clear explanation of what has been descoped to reach that price
• No named clinical references, or references that turn out to be general commercial fit-outs when checked
• A vague or unrealistically fast programme that does not account for phased, occupied-building working
• No clear evidence of CDM competency or a credible answer about who will act as Principal Contractor
• Reluctance to commit to out-of-hours working for noisy or disruptive tasks

How Do You Manage the Contractor Once Appointed?

Appointing the right contractor is the start of managing the project, not the end of it. Regular site progress meetings, a defined snagging process before each phase is signed off, and payment milestones tied explicitly to phase completion and sign-off — rather than simply to elapsed time — keep the programme honest and give the practice leverage if quality or pace slips.
