Hiring a Contractor in Edinburgh 10 Practical Questions

Ten questions to ask before you hire a contractor in Edinburgh

Who you hire decides more than anything else whether you end up with a home you love or one you resent. And most of that is settled in the first meeting. Walk in without a list of questions and you are trusting the contractor’s marketing. Walk in with these ten and the conversation goes where it should have started: evidence, accountability, process.

This is for people doing up Edinburgh tenements, villas, Georgian townhouses and main-door flats. The regulatory side leans on the 2026 Scottish Building Standards, the NHBC 2026 technical handbook, the Tenements (Scotland) Act 2004 and the Consumer Rights Act 2015.

Question 1: accreditations and evidence

Start here, because credentials filter out the no-hopers before you get into the harder questions. Ask to see the paperwork, not the logos on a website.

The Federation of Master Builders (FMB) actually vets members. Minimum twelve months trading history, a check on credit and financial standing, and an on-site inspection by an independent body (BBA or RISA). Get the contractor’s FMB membership number and check it yourself on the FMB “Find a Builder” database.

On bigger, more complicated jobs, CIOB Chartered Building Company status is the higher bar. It needs at least fifty percent of the board to be Chartered Members (MCIOB or FCIOB), and the firm gets an independent corporate assessment every five years covering governance, transparency, quality management and health and safety.

NHBC registration matters when there are structural warranties in play. CITB engagement (the Construction Industry Training Board) tells you the workforce has a route to keeping up with the 2026 Scottish Building Standards changes.

Question 2: three recent references from comparable Edinburgh projects

A general portfolio is easy to dress up. Period-property references matched to your job are not. Ask for three projects finished in the last two years, same building type (tenement, villa or terraced period property) and similar scope (structural alteration, stone restoration, internal reconfiguration).

Two years is not arbitrary. It keeps the references current with the team and management the firm actually has now, and it covers the run-up to the 2026 changes, so you can find out whether they have really been through the current building warrant process with Edinburgh Council.

When you ring those references, get into the detail. Did they use lime mortar matched to Craigleith or Hailes sandstone? Did they issue a completion certificate? Did they deal with the Council’s building standards team? Did the programme hold, or did it slip?

Question 3: written programme of works and trade sequencing

The programme is where the professionals separate from the chancers. Ask for a written one with the critical path, the order the trades come in, and the drying times built in.

Lime work is where a weak programme falls apart. Traditional internal lime plastering is a three-coat process. Each coat needs seventy-two hours minimum to harden before the next coat or any follow-on trade goes near it. A contractor who tells you the electrician can start the day after the scratch coat has just told you he does not understand lime. It gains strength by slowly taking up CO2 in the presence of moisture, and it needs scouring between coats to compact it against shrinkage. Rush it and the finish fails.

Outside work runs to its own rules. Chimney repairs, lime pointing, stonework, all weather-dependent. The 2026 NHBC guidance on cold-weather rendering is specific about it. A proper programme leaves room for weather so the materials are not compromised at the first cold snap.

Question 4: quote structure, labour and materials itemised

A proper quote splits labour and materials out separately. There is a practical reason: high-end refurbishments usually carry Prime Cost (PC) Sums and Provisional Sums for bespoke materials you want to pick later. Keep labour separate and you can fix the installation cost while you are still deciding on the material.

A full quote covers labour per trade or task, itemised materials with quantities and qualities, scaffolding and access (rope-access surveys where there is external masonry), waste management and skip licences, and PC sums with clear allowances. A single lump sum with no breakdown is a red flag. You cannot price variations against it and you cannot check whether the payment schedule is fair.

Question 5: insurance cover and joint names

Insurance is the cheapest risk you will ever cover off. The bit people miss on period work is joint-names cover.

A joint-names policy covers you and the contractor under one policy, treated as a single insured. It stops the insurer chasing either of you for an insured loss. That matters in a tenement, where a fire or flood from contractor negligence can hit the flats next door, the shared stair, or the listed fabric the job is meant to be protecting.

Standard contractor’s insurance usually covers “the works” but not “the existing structure.” In a high-value Edinburgh villa that gap is enormous. JCT Option C in the Minor Works or Intermediate contracts routes joint-names cover for the existing structure through you, the homeowner, which keeps any insurance proceeds in your hands.

Question 6: named project lead and weekly communication cadence

Ask who is running your job day to day. Not the firm, the person. Name, phone number, email. Not “our office team” and not “the site crew.”

Sort out how you will talk in that first meeting: a weekly site meeting, written updates in between, a clear route for raising problems. A CIOB Chartered Company will often name a “Responsible Officer” who sits on the board, so you have a direct line to accountable management. The FMB Code of Conduct requires regular written client communication. If a contractor treats keeping you informed as an afterthought, the scope and the schedule will drift the same way.

Question 7: building warrant and Listed Building Consent management

In Scotland the building warrant is the legal permit for most refurbishment touching structure, drainage, heating systems or major alterations. On Edinburgh period property it is nearly always needed. A competent contractor works with your architect and engineer so the application meets the updated 2026 technical handbooks (Section 2 fire, Section 3 environment, Standard 2.15 fire suppression) before it goes in.

If the property is listed or in a conservation area, Listed Building Consent comes into it too. Your contractor should know the “traditionally constructed buildings” definition in the 2026 Section 0 General updates, and know how to specify lime plaster, sash-and-case window repairs and other heritage-appropriate materials that keep both the conservation officer and the building standards surveyor happy.

Skipping the warrant is not a shortcut. It can bring fines and enforcement action, and it can leave the property unmortgageable when you come to sell.

Question 8: variations and change orders

Period properties always throw up surprises once the strip-out starts. Rotten joist ends, failed lath and plaster, original lead pipework, asbestos from some 1960s botch. There will be variations. The only question is how they get priced and signed off.

A proper contractor uses formal change orders. Every change written down, with its effect on cost and timeline spelled out, and signed by you before the work starts. Verbal variations are where “final bill shock” comes from, and they are a nightmare to enforce. The Consumer Rights Act 2015 says services must be performed with reasonable care and skill, and a paper trail of change orders is what you fall back on if you ever have to enforce that.

Question 9: payment schedule tied to milestones

Payments should be tied to completion milestones you can verify, not dates on a calendar. A typical shape for a period refurbishment:

• Mobilisation and site setup: ten to fifteen percent.
• Completion of structural works and first fix: twenty-five to thirty percent.
• Completion of plastering and second fix: twenty-five to thirty percent.
• Practical completion (final finishes and testing): twenty to twenty-five percent.
• Final handover (completion certificate issued): five to ten percent.

Insist on a retention as well, usually two and a half to five percent of each payment, held back until the end of the defects liability period. That is what gives the contractor a reason to come back and clear the snags after the main works are done. Anyone asking for a big deposit up front, fifty percent or more, with no milestone schedule behind it, is either short of cash or not professional. Not who you want in your house for six months either way.

Question 10: snagging and defects liability process

Every refurbishment throws up snags. What you want to know is the process. Practical completion should mean a joint walkthrough to build a snagging list with a clear timeline to fix each item. The contract should carry a defects liability period, usually six to twelve months, where the contractor is legally on the hook to come back and put right anything down to their workmanship or materials.

Better Edinburgh contractors in 2026 often carry insurance-backed guarantees that hold even if the firm goes under. Check how disputes get resolved: FMB members use independent dispute resolution, CIOB firms have formal complaints pathways. Both beat ending up in court.

Red flags to listen for

How they answer tells you as much as what they answer. Listen for these.

• Vague or evasive responses: “We’ve done hundreds without a warrant” is a red flag. The 2026 Section 2 fire and Standard 3.3 drainage standards are tighter than they used to be.
• Verbal over written: Dodging JCT or FMB contract templates says the firm is working outside 2026 professional norms.
• Unusual upfront demands: A fifty percent deposit before any materials are ordered points to a cash-flow problem.
• Dismissal of accreditation: “Twenty years of experience, I don’t need badges” ignores that the 2026 technical requirements have moved past what experience on its own now covers.

How to independently verify the answers

Three sources of independent evidence you can use in 2026.

Companies House: check the filing history, the directors, and whether the pattern looks like a “burner company” that keeps liquidating and re-registering under similar names. Stable firms have years of clean filings behind them.

Scottish Building Standards Register: Edinburgh Council publishes Part I data (basic property and application status) online. Part II holds the fuller documents for interested parties. You can check whether the contractor has actually filed and closed out warrants on properties like yours.

Edinburgh Trusted Trader: the scheme run with the City of Edinburgh Council and Trading Standards Scotland vets members and holds them to a code of practice with managed dispute resolution. Not every heritage specialist is on it, but being listed is one more layer of protection for you.

Tenement-specific considerations

Tenements bring legal and practical layers a detached villa never does. The Tenements (Scotland) Act 2004 sets out who is responsible for the common parts: roof, close, foundations. Three things worth raising in that first meeting.

The property factor. A lot of tenements are run by a professional factor. Check the Scottish Property Factors Register before you start. Anything touching common property, moving waste pipes into the shared stack, repairing a mutual chimney, needs the factor involved and the neighbours on side.

Statutory notices and scheme decisions. Work on shared structure (roof, mutual chimney, common drainage) may need a statutory notice to neighbours setting out what the work is, when it starts and how long it runs. Scheme decisions bind all the owners once the notification is done properly, with a twenty-eight day appeal window through the sheriff court.

Common drainage and flues. In a traditional tenement these are shared. Change a kitchen or bathroom layout in a way that interferes with the common drainage stack or the shared flue and it is not routine work. It needs coordination, consent, and 2026 Section 2 compliance for fire and smoke spread.

What a good contractor answers like

Across all ten questions, a good answer has a shape. Specific, evidenced, written. Specific: named trades, exact drying times, precise material specs. Evidenced: FMB numbers, NHBC registration, insurance certificates, references whose phones actually pick up. Written: programme as a Gantt, quote itemised, variations as change orders, payment tied to milestones on paper. The firms that can put all that in front of you are the ones worth having.
