How to Use: Building Regulations Compliance Evidence Pack Index (Dutyholder Approach)

Purpose and outcome

This resource is a practical index and checklist to help you collect, organise, and prove Building Regulations compliance as the job runs (not at the end). It supports the dutyholder approach by making sure the right people can demonstrate what was designed, what was built, what was checked, and what evidence backs it up.

Good completion looks like: a clear, well-filed evidence pack that links approvals, current design info, inspection/hold-point records, product evidence, test certificates, agreed changes, and as-built details—so Building Control and the client can follow the compliance trail without gaps.

What this helps you demonstrate (in plain English)

• The design was suitable: you worked to the latest approved/issued drawings and specs, with key details covered (structure, fire, thermal, ventilation).
• The work matched the design: inspections and photos show what was actually installed, especially hidden works.
• Products were appropriate: you can show what products were used and why they meet requirements (datasheets/DoP/certification as relevant).
• Changes were controlled: substitutions and on-site design changes were recorded and agreed (not just “we always do it this way”).
• Systems were tested: commissioning and test results are received, legible, and match the address/job.

Who uses it (and who does what)

When to use it (trigger points)

• Day one (set-up): create the folder structure, print the checklist, add project details, and agree “who supplies what” with each trade.
• Before each stage starts: check what evidence is due and confirm hold points (especially for hidden works).
• Every week: 10–15 minutes to file, tick off, and chase missing items.
• Before covering up: stop and confirm photos + inspection notes + product evidence are saved.
• Two to four weeks before completion: run a “gap check” and start collecting final certificates and as-builts early.
• Handover: final tidy-up and issue the pack to the client (retain your copy).

Before you start (what you need ready)

• Project basics: site address, client details, key dutyholders/contacts, and Building Control route/details.
• Current design set: latest drawings/spec, structural details/calcs (where relevant), and key compliance details (fire stopping approach, insulation line, ventilation strategy).
• Competence info for key trades: registration/certification where required (e.g., electrical, gas) and any specialist areas (e.g., fire stopping) as agreed on the job.
• Trade evidence plan: each subcontract package: what evidence they will provide and when (don’t leave this vague).
• Simple photo plan: what you’ll photograph at each stage and where you’ll store it.

Site rule: if it will be hidden later (concrete, backfill, plasterboard, screed, ceilings, cladding), collect the evidence before you close it up.

How to complete it (step-by-step)

Review and sign-off (what “checked” means)

• Weekly check (site manager/foreperson): new evidence filed, checklist updated, upcoming hold points planned, and any missing certs chased.
• Stage reviews (PC lead/owner): at end of groundworks, before closing up first fix, and pre-completion. Focus on structure, fire stopping, insulation/thermal line, ventilation, and test/commissioning evidence.
• Escalate early if: you can’t evidence hidden works, there’s a compliance-critical substitution, Building Control queries an element, or a subcontractor won’t provide certificates/commissioning sheets.

Recordkeeping (storage, version control, retention)

• One “source of truth”: keep evidence in one project folder using the resource’s folder index.
• Printed + digital: keep a printed copy on site for quick ticking/notes, but make the digital folder the master record. Scan/photograph updated pages regularly.
• Version control: latest drawings in the main design folder; superseded revisions in Archive. Never overwrite without changing name/revision.
• Photos: upload weekly (minimum). Use date + area + short description so they still make sense later.
• Retention: keep the full pack for the period required by your contract and insurer, and any statutory expectations for the job type. Apply one consistent company rule.

How often to update it

• Minimum: weekly.
• Immediately after: Building Control visits, hold-point checks, delivery/installation of regulated products, completion of any tested system, and any design/product change.
• Final week: update daily so handover doesn’t stall on missing paperwork.

Common mistakes (and how to avoid them)

• Leaving evidence until the end. Fix: schedule a weekly admin slot and treat it as part of the build.
• Covering up without proof. Fix: hold points—no board/screed/backfill until photos + checks are saved.
• Unlabelled photos. Fix: one wide shot + one close-up + a location note (plot/room/elevation).
• Substitutions not recorded or not agreed. Fix: log it before ordering/installation and capture who approved.
• Missing subcontractor certificates. Fix: set expectations at order stage and link completion/payment to receiving the right evidence.
• Old drawing versions in circulation. Fix: issue a “current set” and remove/mark old copies; archive digital superseded versions.
• Evidence scattered across devices. Fix: one folder, clear structure, named files, and weekly upload from phones.

Worked example (realistic site scenario)

Job: small extension with structural steel, upgraded insulation, new ventilation, and full electrical work.

1. Week 1: set up folders + print checklist. File Building Control notice/approval and latest drawings/spec. Record roles/contacts.
2. Groundworks: before pour/backfill, take photos of formation and drain runs; save inspection notes and any drain test evidence.
3. Steel install: photograph bearings/connections; file engineer details; log any on-site changes with who agreed.
4. First fix: photograph insulation coverage/thickness and fire stopping at penetrations before plasterboard; file product evidence for what was used.
5. Completion: collect EIC and ventilation commissioning results as soon as each system is finished; do a gap check two weeks before handover; file final Building Control completion/acceptance evidence and issue the handover pack.
