AskBaily vs Checkatrade — 1 vetted contractor, zero lead fees

AskBaily and Checkatrade are built for the same UK homeowner problem — finding a tradesperson or contractor you can actually trust — but the two platforms arrive at the answer through opposite structural routes. Checkatrade, operated by Checkatrade.com (UK) Ltd and accessible at https://www.checkatrade.com, is a vetted-membership directory. Tradespeople pay an ongoing subscription to be listed; homeowners browse the directory, read reviews, and contact whichever tradespeople they choose. AskBaily, operating in London, Edinburgh, Manchester, and ten additional international markets staged through 2028, runs a 1-to-1 AI-scoped matching model. A homeowner has a conversation with Baily, the scope is structured, and exactly one verified contractor is introduced. The difference is not about which brand is "better" — Checkatrade has built a genuinely useful product over more than two decades. The difference is about which problem each platform actually solves well, and for what size of job.

How Checkatrade's membership model actually works

Checkatrade's revenue comes from its tradesperson members, not from its homeowner users. Published membership tiers sit around £40 per month at entry level, rising to several hundred pounds per month for enhanced Gold or Premium tiers that include additional visibility, more photos, and better directory placement. The company's own pricing guidance is published at https://www.checkatrade.com/trade — any specific figure quoted here should be verified directly against their current tier sheet, because Checkatrade adjusts pricing by trade category and region.

At signup, Checkatrade runs what it describes as a 12-point check. That typically covers identity verification, confirmation of a business address, a Companies House check where applicable, insurance declaration, basic criminal-record screening, and trade-specific credential checks — for example, a Gas Safe Register number for a heating engineer, an NICEIC or NAPIT registration for an electrician, or an FMB or TrustMark affiliation for builders. Checkatrade then collects homeowner reviews after each completed job. Reviews are moderated but homeowner-written, and the scoring system is the primary signal a homeowner sees when browsing the directory.

The mechanic for the homeowner is: search by trade and postcode, read reviews, call or message one or several tradespeople directly, and pick one. Checkatrade does not route a specific tradesperson to a specific homeowner. It is a directory with vetted supply and a review layer on top. That is a legitimate product, and for small and medium domestic repair jobs — a dripping tap, a blown consumer unit, a boiler service, a roof tile replacement — it is often the fastest and most honest way to find someone decent locally.

The economic structure is worth naming plainly. A tradesperson pays Checkatrade every month whether they close a job or not. Monthly membership is a fixed cost of being visible. If a tradesperson on a £40/month tier closes two £400 boiler services per month sourced from the directory, the membership is trivial at 5% of revenue. If they close twelve £4,000 bathroom refits per year, it is closer to 1% of revenue. If they close nothing in a given month, the £40 is still due. Tradespeople budget for membership the way they budget for van insurance.

AskBaily's 1-to-1 matched model for the UK

AskBaily is structured in the opposite direction. A homeowner opens a conversation with Baily, an AI built on Google's Gemini 2.5 Flash with UK-specific domain tools layered on top. Baily conducts a scope interview covering project type, scope boundaries, budget range, timeline, and regulatory constraints — Building Regulations Part P for electrical work, Part L for energy performance on extensions, Part G for water, Gas Safe requirements for any gas work, Party Wall Act 1996 obligations for semi-detached and terraced properties in London, Article 4 Direction checks in conservation areas, and listed-building consent for any Grade I or Grade II property.

The scope goes to AskBaily's UK matching engine, which runs four verification filters. First, trade and city match — London, Edinburgh, or Manchester, with the correct trade class for the scope. Second, live regulatory-body verification at the moment of match. For a gas engineer, the check hits the Gas Safe Register at https://www.gassaferegister.co.uk and confirms the engineer's number is currently on register for the scope categories required. For an electrician, the check confirms NICEIC, NAPIT, or ELECSA approved-contractor status — Part P self-certification depends on registration with a competent-person scheme, and Checkatrade's baseline check is a one-time signup, whereas AskBaily re-verifies at match time. Third, insurance currency — public liability £2m minimum, employer's liability £10m where the contractor has staff, and professional indemnity where design is in scope. Fourth, prior-project-type fit against the contractor's completed portfolio at renovation scale.

A failure on any of those four filters aborts the match. One contractor is introduced. Not a directory of twelve. One. There are zero membership fees paid by that contractor. AskBaily's revenue comes from an 8–15% tiered take-rate on the closed job price, paid by the contractor on completion — which means AskBaily's revenue is only earned when the homeowner's project is actually delivered, not on the calendar first of the month whether anything happened or not.

Side-by-side comparison

Checkatrade's two genuine advantages are review depth and geographic coverage. A directory with over two decades of homeowner-written feedback across every UK postcode has a signal density that a first-year matched-pro product cannot replicate overnight. Stating that plainly matters more than pretending otherwise. AskBaily's advantages are scope structure, live regulatory re-verification, and cost alignment with closed work rather than with calendar membership.

The verification contrast

Both platforms verify credentials. The difference is when and how often. Checkatrade verifies at the point of membership application — the tradesperson presents their Gas Safe number, NICEIC registration, insurance certificate, and Companies House record, and Checkatrade's vetting team confirms each against the relevant register at that moment. Periodic re-checks occur, but the published cadence is not stated explicitly and the industry assumption is annual at best for most categories.

AskBaily's matching engine calls the regulator's register API at the moment a specific homeowner is being matched with a specific contractor. If a gas engineer let their Gas Safe registration lapse last week, the Checkatrade directory entry may still show them as "vetted" until the next review cycle, whereas AskBaily's live check will fail the match outright and route the homeowner to a different verified engineer. Part P self-certification under Building Regulations Schedule 3 depends on the electrician being a current member of a competent-person scheme — Part P was amended in 2013 and again in policy guidance in 2024, and competent-person scheme membership is a moving target. Live-at-match verification is the architectural answer to that volatility.

The same applies to TrustMark, which is the government-endorsed quality scheme at https://www.trustmark.org.uk. A TrustMark-registered business has agreed to trade standards covering customer service, technical competence, and trading practices. TrustMark status can be withdrawn, and the withdrawal happens on a different clock than directory refresh cycles. AskBaily's matching engine treats TrustMark as a live-queried attribute, not a cached one.

The scope coverage contrast

Checkatrade's sweet spot is the £50–£5,000 domestic repair and single-trade job market. Plumbers, electricians, roofers, boiler engineers, painters and decorators, handypersons, carpet fitters, chimney sweeps, pest controllers — the directory has deep supply across all of them, with review volume that lets a homeowner make a decent choice in ten minutes. For a leaky kitchen tap in Clapham or a broken extractor fan in Jesmond, Checkatrade is arguably the strongest tool available in the UK market, and it would be silly to recommend anything else.

AskBaily's sweet spot is the £25,000+ renovation market where project scope has real engineering, regulatory, and sequencing complexity. A full kitchen remodel in Islington where a lateral wall will be partially opened and the Party Wall Act triggers on a terraced property. A loft conversion in Edinburgh where the neighbour's Grade II listed status blocks dormer modifications and a Conservation Area consent is required. A basement dig in South Manchester where Building Control pre-application talks are essential and the structural calc needs a design-and-build contractor, not a general builder. These jobs need scope structure before supplier choice. Baily AI spends fifteen to twenty minutes with the homeowner on scope boundaries, permits, and budget realism before introducing a contractor — which is impossible inside a directory browse model.

The homeowner experience contrast

On Checkatrade, the homeowner is doing the matching work themselves. They read five directory entries, cross-reference reviews, call three tradespeople, explain the job three times, wait for three quotes, and make a decision. This is a well-understood process and many homeowners enjoy the control. It is particularly good when the job is well-defined — "replace my boiler, same location, condensing combi, 24kW" — because the quotes are directly comparable.

On AskBaily, the homeowner is offloading the matching work to the AI. They explain the job once to Baily in conversation, Baily refines the scope, Baily re-verifies a shortlist and introduces exactly one contractor, and the contractor arrives already briefed on scope and budget. This is particularly good when the job is not well-defined — "we want to open the ground floor and maybe do something about the layout and the kitchen is old and we think we might need planning" — because the homeowner does not need to become a project manager to triangulate between three quotes on work they cannot compare like-for-like.

Neither experience is universally better. They are better for different types of homeowners on different types of jobs.

Regulatory-specialist capability

UK Building Regulations are genuinely complicated and the penalty for getting them wrong can be severe. The main stack:

• Part A (Structure) — walls removed, loft conversions, extensions requiring structural calcs
• Part B (Fire Safety) — including the post-Grenfell changes affecting cladding, compartmentation, means of escape
• Part E (Resistance to Sound) — relevant for basement dig and flat conversions
• Part F (Ventilation) — MVHR or extract fan requirements after airtightness improvements
• Part G (Sanitation, Hot Water and Water Efficiency) — unvented cylinders require G3 qualification
• Part L (Conservation of Fuel and Power) — energy performance, U-values, updated in 2022 with Future Homes Standard trajectory
• Part M (Access to and Use of Buildings) — relevant on larger extensions
• Part P (Electrical Safety) — the self-certification framework that NICEIC/NAPIT/ELECSA membership supports

Alongside Building Regs, the separately-notified registration stacks: Gas Safe Register (HSE-appointed), NICEIC / NAPIT / ELECSA (Part P competent-person schemes), NIC EIC (fire and emergency lighting), MCS (renewables and heat pumps), TrustMark (government endorsement). London layers on Party Wall Act 1996 obligations for any wall or excavation within 3 metres of a boundary. Scotland runs a parallel Building Standards regime administered by local authority Verifiers rather than England's Building Control. Conservation areas impose Article 4 Directions. Listed-building consent sits on top of planning.

Checkatrade records a tradesperson's primary registrations at signup. AskBaily's scoping engine surfaces the specific regulatory triggers of a specific project and then matches to a contractor whose verified portfolio includes that regulatory pattern — a loft specialist who has cleared Building Control on a Party Wall scope before, rather than a general builder who happens to have the right Gas Safe number.

Hostility rating — and who should use what

We rate Checkatrade as hostility level 2: the products compete in the same category but for non-overlapping job types most of the time. Checkatrade is primarily a repair-and-single-trade directory; AskBaily is primarily a renovation matching engine. They share the word "vetted" and not much else.

Use Checkatrade when: the job is a single-trade domestic repair in the £50–£5,000 range, the homeowner enjoys picking their own tradesperson from a review-sorted list, the postcode is outside AskBaily's current Wave 1 coverage (AskBaily UK launched in London, Edinburgh, and Manchester under the Phase 8 international plan; the rest of the UK is staged through 2027), or the homeowner already has a Checkatrade tradesperson they trust and want to rehire.

Use AskBaily when: the job is a renovation at £25,000 or above with genuine scope questions, Building Regs apply, the property is in a conservation area or listed, a Party Wall Award is in play, the homeowner does not want to manage the quote-triangulation process themselves, or the homeowner wants AI-driven scope structuring before talking to anyone. London, Edinburgh, and Manchester have live AskBaily partner-GC coverage as of 2026-04-20; other UK cities follow in the Phase 8 rollout.

Frequently asked questions

Does Checkatrade charge the homeowner? No. The homeowner-facing directory is free to use. Tradespeople pay ongoing monthly membership in exchange for being listed. That cost is absorbed across the tradesperson's pipeline and shows up, to a minor extent, in the quotes they deliver.

How reliable is Checkatrade's vetting? It is a one-time signup check plus periodic re-verification, which is meaningfully more rigorous than an un-vetted directory but less rigorous than a live-at-match verification pass. For fast-moving registrations like Gas Safe or Part P scheme membership, the gap between "vetted at signup" and "currently registered" can matter.

Is AskBaily available outside London, Edinburgh, and Manchester? Not yet. Phase 8 Wave 1 goes live across those three UK cities alongside Sydney, Melbourne, Singapore, Auckland, and Dubai. Additional UK cities — Bristol, Leeds, Birmingham, Glasgow — are staged in Wave 2 through 2027. For postcodes outside current coverage, Checkatrade or MyBuilder are the obvious alternatives.

What if my Checkatrade tradesperson has given me a quote on a renovation? That is a perfectly reasonable starting point. AskBaily is not a replacement for an existing relationship a homeowner trusts. What AskBaily adds is live regulatory verification and AI-structured scope as a parallel sanity check — a second opinion on scope, permits, and budget realism, separate from the tradesperson quoting the work.

How does AskBaily verify Gas Safe and NICEIC at match time? The UK matching engine hits the Gas Safe Register API and the NICEIC approved-contractor roster directly at the moment a specific homeowner is being matched with a specific contractor. If the registration has lapsed, been downgraded, or been withdrawn since the contractor joined AskBaily, the match aborts and a different verified contractor is routed instead. This is structurally different from a directory's cached badge.
