UK contractor directories compared: choose the right search model
A contractor directory can introduce you to firms you did not know. It cannot, by itself, decide whether a particular firm is right for your work. The most useful comparison is therefore not a list of stars or a single “best contractor directory” winner. It is a comparison of how each service creates a shortlist, what evidence you can see and what you must still check yourself.
The word *contractor* covers very different buyers. A homeowner looking for a plumber wants local availability, examples of similar jobs and an understandable quote. A facilities team replacing plant in an occupied building may need evidence of competence, insurance, supervision and coordination. A principal contractor sourcing a specialist subcontractor may use a formal prequalification scheme. Those buyers should not expect the same answer from every directory.
This guide compares current directory models using the providers' own descriptions, checked on 1 October 2026. Services, membership terms and prices can change. Always read the current provider terms and ask the contractor for job-specific evidence before appointment.
Four directory models you will encounter
| Model | What it helps you do | Typical limitation to investigate |
|---|---|---|
| Local trade search | Search by trade and area, browse profiles and contact a firm. | A profile or review may say little about the people and method proposed for your particular job. |
| Job-posting marketplace | Describe a job and receive responses or matched trades. | The response process can feel convenient, but you still need to compare scope, identity and evidence. |
| Construction supplier/prequalification network | Find firms within a construction procurement or assessment framework. | A scheme assessment is not a substitute for reviewing site-specific capability and arrangements. |
| Compliance-focused discovery destination | Search firms by service or location and use profile information as a starting point. | Do not treat a listing or displayed status as a legal determination of suitability. |
These are search models, not grades of safety. One supplier may appear on several services, and a good supplier may not subscribe to the service you searched. Coverage depends on trade and location. Start with the model that fits the buying task, then test individual candidates against the work.
Checkatrade: trade and postcode search
According to Checkatrade's current search guide, users enter a description of the work and a postcode, then browse profiles, reviews and examples before requesting a quote or contacting a trade. This is a straightforward route for a local job where you want to compare several firms.
Read the scope of a profile carefully. An example project can help you judge whether a contractor has done similar work, but it does not tell you who will attend your site or what insurance and working method will apply. Ask those questions directly. Checkatrade's own explanation of its checks is a claim about its membership process, not a guarantee that each proposed job will be suitable or risk free.
The service is particularly relevant when you know the trade and postcode. If the task crosses several trades, has unusual hazards or will take place in an operating workplace, your buyer process needs to go beyond a profile comparison. State the scope and interfaces clearly in each enquiry so the quotes describe the same job.
Rated People: job posting linked to Checkatrade
Older directory comparisons often describe Rated People as an entirely separate pool of tradespeople. That description needs updating. Rated People's September 2026 announcement says the Checkatrade Group acquired selected Rated People assets, including the brand and website, and that jobs posted through Rated People are now matched with Checkatrade's network.
Rated People still presents a job-posting route: describe the work and let tradespeople respond with quotes. For buyers who prefer to state a task once rather than browse many profiles, that model may be convenient. But when you compare it with Checkatrade, do not assume you are testing two wholly independent supplier networks. Ask how the particular enquiry will be distributed and evaluate the actual responses you receive.
A job-posting service does not write your specification for you. State the desired outcome, access limits, timescale and any significant site conditions. If an offer is much cheaper, check whether it includes the same materials, waste removal, supervision and completion evidence. The directory route is only the first step in making a fair comparison.
TrustATrader: search by trade and location
TrustATrader's current site provides trade and location search, with trader profiles and reviews. It is another way to find local candidates, especially when a buyer wants to browse rather than post a single job.
Apply the same questions to each listing regardless of its branding. Does the business actually cover your location? Are the examples relevant to the proposed work? Are recent reviews about the same type of service? Does the named business on the profile match the legal business on the quote and insurance evidence? A directory may set admission conditions, but you need to know what those conditions are, when evidence was last checked and what they do not cover.
Do not compare providers solely by review score. The number, recency and subject of reviews matter, and reviews cannot establish a worker's current competence for a specialist task. A buyer should use them alongside the quote, evidence and a conversation about how the work will be delivered.
Constructionline: a construction procurement model
Constructionline's membership information describes a supplier membership and prequalification proposition for construction. That is a different buying context from finding someone to repair a domestic tap. A construction buyer may value common assessment information, supplier discovery and a structured starting point for procurement.
The right question is whether the scheme information corresponds to the work you are appointing. Check the legal entity, assessment level, scope and currency, then ask for project-specific evidence. The Health and Safety Executive's explanation of third-party conformity schemes warns that an assessment is not proof a contractor can manage the risks of a particular site. A procurement badge can save repeated general questions while leaving the actual appointment decision with the buyer.
For membership and assessment levels, use Constructionline's current membership information. This comparison focuses on which directory model fits your search.
Where Complys fits
Complys offers a trade and location search and a contractor directory. As with any directory, use a listing only to discover possible suppliers or see how a profile is presented. Treat the results as a shortlist, then ask the supplier for evidence relevant to the proposed work. A listing is not an automatic finding that a company or worker is legally compliant for your job.
If you are coordinating many contractors over time, a directory is only part of the workflow. You also need a way to request, review and maintain the records relevant to appointment and work on site. Ask any software vendor to demonstrate those steps in its current released product. This guide does not claim any automated approval, certificate validation or legal determination by Complys.
How to compare contractor directory costs
“What does a contractor directory cost?” has two answers: the price to use the service and the total cost of obtaining a suitable contractor. Provider charging models change, and some fees affect the listed business rather than the person searching. Do not rely on an old comparison's membership or lead price. Ask each provider for current terms.
For a buyer, test the practical cost of using each route:
- Is search free, or does contacting or posting a job trigger a charge?
- Will the provider introduce you to multiple firms, or display profiles for you to choose?
- Is the service useful in your postcode and specialism?
- Can you compare quotes on a common specification, or must you repeat the enquiry?
- What information appears before you contact a supplier, and what must you request separately?
- If a project requires a formal supplier assessment, does the directory actually provide that assessment or just a listing?
For a contractor deciding where to list, ask a different set of questions. What is the current membership or lead charge? Which enquiries are included? What area and trades will your profile cover? Who owns the customer relationship and reviews? What happens if you leave? A low apparent lead cost is not good value if the enquiries are outside your trade or location. Equally, a paid membership can be useful if its audience matches the work you want. These are commercial judgments, not universal rankings.
A decision table for common buyer situations
| Buyer situation | Start with | Then verify |
|---|---|---|
| Small local repair or improvement | Trade and postcode search, or a job-posting route. | Identity, relevant experience, a clear quote, insurance where appropriate and references. |
| Several quotations for one defined job | A platform that can send the same brief or let you contact several firms. | Whether each response prices the same scope, materials and access conditions. |
| Specialist construction subcontract | A construction supplier network and relevant industry contacts. | Assessment scope, technical competence, people, method and coordination for the actual site. |
| Ongoing workplace contractor panel | A discovery source plus a repeatable selection process. | Current evidence, change control, supervision and arrangements across each project. |
| Scarce trade in a specific area | More than one search model and direct recommendations. | Availability, genuine local coverage and ability to perform the work safely. |
There is no need to pick only one source. Two directories may show overlapping firms. That is useful for discovery but should not be mistaken for two independent references. Where a decision is high consequence, direct references, issuer checks and a conversation about the proposed work add more than another search result.
What a directory cannot settle for you
Directories can make a market easier to search. They cannot know every condition at your property or site, every change in the contractor's staff, or how a subcontractor will carry out the work once appointed. Even a current assessment or membership badge has a defined scope and date. If you need a contractor for a regulated activity, identify the relevant registration or licence and check the official source for the precise work category.
For construction in Great Britain, the HSE's CDM guidance addresses the skills, knowledge, experience and organisational capability needed for those appointed. Dutyholder arrangements depend on the project, including whether the client is domestic or commercial. The directory does not decide those roles. The HSE's guidance on using contractors also emphasises selection, cooperation, information and supervision.
The simplest way to avoid over-reading a listing is to write down what you have actually learned. A profile may give you a name, trade, area and reviews. A certificate may show a scheme assessment. A call may explain availability. None is the same as a decision that the whole package is suitable for this job. Use the HSE's contractor selection guidance for the later evidence and appointment steps.
Choosing a directory without chasing a “best” badge
Begin with the work, not the directory name. Identify the trade, location and risk of the appointment. Decide whether you want to browse firms, post a brief, use a construction assessment network or build an ongoing supplier panel. Compare the information each service actually gives you at the point of selection. Check current terms directly with the provider.
Next, run the same enquiry through a small number of suitable channels. Notice whether the same firms appear, whether profiles provide useful evidence and whether respondents understand the scope. Stop adding sources when you have a credible shortlist. Spend the saved time examining the firms rather than collecting more directory badges.
Finally, record why you chose the contractor. If a directory or membership was one piece of evidence, say so. If you checked a registration or insurance document, record when and against which legal entity. If the work changes, revisit what you relied on. That makes the selection explainable without pretending the directory has made a site-specific compliance decision for you.
Next step: Browse a directory to build a shortlist. Check each candidate against your particular job and record what the listing has actually established. Use HSE's contractor-selection guidance when deciding what evidence and supervision the work requires.
