Renovation and home-service regulation is genuinely fragmented — contractor licensing, permits, and building inspection are handled at the state, provincial, or local council level in the US and Australia, while the UK relies on voluntary/government-endorsed vetting schemes rather than licensing at all. This directory keeps that structure honest: where a single national resource genuinely exists, it's linked directly; where it doesn't, the copy says so and points you to the right starting point instead of a guessed link.
Section 1 · Contractor License Lookup
Check a contractor's license or vetting status before you hire — the mechanism differs sharply by country.
Check a contractor's license in California (US)
What: The US has no single federal contractor license registry — each state runs its own. CSLB is shown here as a representative example of what a state licensing board check looks like; search "[your state] contractor license lookup" for your own state's board.
When to use: Before hiring, to confirm a license is real, active, and covers the right category of work.
Check a builder or tradesperson's licence in NSW (Australia)
What: Australian licensing is state-based, not national. NSW is shown here as a representative example; check your own state or territory's fair trading/consumer affairs body for its own register.
When to use: Before hiring, to confirm a builder or tradesperson's licence is current.
Find a government-endorsed tradesperson in the UK
What: The UK does not require contractor licensing the way the US and Australia do. TrustMark is the government-endorsed quality scheme for vetting tradespeople — not a legal license.
When to use: Before hiring, to find or check a vetted tradesperson.
Federation of Master Builders (FMB) — trade association vetting →Section 2 · Building Permit Offices
There is no single national permit office in any of these countries — always start with your local municipal, county, or council authority.
Find your local building control body in the UK
What: Helps you find the correct local building control body for your project.
When to use: Before starting work that may require building regulations approval.
Finding your local permit office in the US or Australia
What: Neither country has a single national permit office. Search "[your city/county] building permit department" or check your local council's website directly.
Section 3 · Building Inspectors
Find an independent, certified inspector to check work before you buy, before final payment, or if you suspect a problem.
Find a certified home inspector in the US
What: A directory to find a certified home inspector.
Find a chartered building surveyor in the UK
What: A directory of chartered building surveyors.
Finding a building inspector in Australia
What: Building surveyors/inspectors are licensed at the state/territory level in Australia, not nationally — direct readers to their state's building authority (see the NSW/VIC context already covered in Section 6's HBCF/DBI entries).
Section 4 · Mediation & Construction Dispute Boards
This section is formal, often binding dispute resolution — distinct from Section 7's general consumer complaint agencies. A board here resolves your specific case with real authority; a Section 7 agency is a first-contact complaint channel.
Get free government conciliation for a Victorian building dispute (Australia)
What: A free, government conciliation service for Victorian domestic building disputes. A DBDRV certificate is required before you can escalate to VCAT.
Use your statutory right to construction adjudication in the UK
What: RICS is an adjudicator nominating body under the Housing Grants, Construction and Regeneration Act 1996 — Section 108 of the Act gives any party to a construction contract a statutory right to refer a dispute to adjudication, whether or not the contract itself provides for it.
File a complaint through a state licensing board's intervention program (US)
What: California-specific, shown as a representative example of the pattern of state licensing board complaint/mediation programs that exist across the US — check whether your own state's board offers something similar.
Section 5 · Gas / Electrical Certified Registers
Confirm the specific trade certification for gas, electrical, or window/door installation work — separate from general contractor licensing above.
Check a gas engineer is legally registered in the UK
What: The official, legally-mandated list of registered gas engineers in the UK — by law, only Gas Safe registered engineers can legally work on gas.
Find a certified electrical contractor in the UK
What: A leading electrical contractor certification body in the UK.
Check a window/door installer is government-authorised in the UK
What: The government-authorised scheme for replacement window/door installers, monitoring building regulation compliance on the homeowner's behalf.
Gas/electrical certification in the US and Australia
What: Electrical and gas safety certification is regulated at the state level in both countries, not nationally — check your state licensing board (see Section 1's pattern) for the relevant trade register.
Section 6 · Home Warranty Providers
Coverage for defects and incomplete work after a project finishes — some mandatory, some private and optional.
Check mandatory home building insurance in NSW (Australia)
What: Mandatory insurance for NSW residential building work over $20,000 AUD, regulated by SIRA.
Check mandatory building insurance in Victoria (Australia)
What: Mandatory insurance for Victorian residential building work over $16,000 AUD, now administered by the Building and Plumbing Commission. Being replaced by a new "Home Warranty" scheme for contracts from 1 July 2026.
Check the standard new-build warranty in the UK
What: The Buildmark warranty covers roughly 70-80% of new UK homes.
A private national structural warranty provider (US)
What: The US has no government-mandated home warranty program nationally. 2-10 HBW is a private commercial provider, not a government scheme — shown here as a widely-used representative example covering builders and homeowners across most states.
Section 7 · Consumer Authorities for Home Renovation
General, first-contact consumer complaint agencies — distinct from Section 4's formal, binding dispute resolution boards.
Get general consumer complaint guidance in the UK
What: General consumer complaint guidance, including home improvement issues.
File a general consumer complaint in the US
What: There's no single federal consumer protection body for home renovation specifically — this federal wayfinding page routes you correctly, and your state Attorney General's Consumer Protection Division is the other first-contact option.
File a general consumer complaint in NSW (Australia)
What: General consumer complaints — distinct from DBDRV in Section 4, which is Victoria's specific binding conciliation scheme. This is a representative state example, not a national body.
Route a cross-border EU consumer complaint
What: Routes a cross-border EU consumer complaint (e.g. hiring a contractor across a member-state border) to the right national body — the same reference used in Kibbo's Telecoms & Utilities directory.
Section 8 · Material Certification Databases
Check that a building material or product actually carries the compliance mark it claims to.
Check an EU construction product's Declaration of Performance
What: A searchable database of Declarations of Performance for CE-marked construction products sold in the EU.
European Commission — Declaration of Performance & CE Marking →Check UKCA marking requirements for construction products (UK)
What: Since 1 July 2025, UK construction products generally require UKCA marking, not CE marking. However, the Construction Products (Amendment) Regulations 2025 — in force from 8 January 2026 — provide transitional continuity, allowing CE-marked products to continue being sold in Great Britain in the meantime.
GOV.UK — Placing UKCA or CE marked products on the market in Great Britain →Check a US safety certification for electrical/building products
What: A widely recognized US safety certification for electrical and building products.
Check mandatory plumbing product certification in Australia
What: Mandatory certification for certain plumbing/drainage products, administered by the ABCB.
Check voluntary innovative building product certification in Australia
What: Voluntary certification for innovative building products, also administered by the ABCB — WaterMark (above) is mandatory plumbing safety certification, while CodeMark is voluntary compliance certification for products that don't fit standard code pathways. Different purposes, same regulator.
