The free app for testers, and an easier way to book tests.

Air tightness, sound and ventilation testers get their jobs, results, photos and certificates in one place, plus work that fits the route they're already driving. Assessors and housebuilders post tests to local testers who are already nearby, check plots are ready and see every result.

Who it's for

One record for the tester, the assessor, the developer and the site

Everyone sees what they need and nothing they shouldn't. Site managers never see prices, and a tester's own customers stay private to them.

How it works

From plot list to lodged certificate

One shared record of each test, from the job being posted to the certificate being uploaded.

  1. Post or import

    Assessors and developers add sites and plots (or import a spreadsheet), set what each plot needs, and post jobs to the marketplace, invite testers they trust, or offer a preferred tester first refusal.

  2. Matched to the route

    Testers see jobs that fit their diary, with the extra driving worked out. The day before, the site manager confirms the plots are ready through a secure link, so nobody drives to a plot that isn't.

  3. Tested and recorded

    Results go in on site, offline if need be. Passes, fails and retests are all kept. The tester lodges with their scheme as now, then uploads the certificate and lodgement reference against the plot.

Supporting local businesses

A network of local independent testers

TestConnect is built for self-employed testers and small testing firms. Together they give housebuilders and assessors one place to book a local tester who runs their own business and cares how the home is built. A job is only shown to testers whose working area covers the site, and those already working nearby that day are alerted straight away.

Money stays local

The fee goes to the local firm that did the test. We take no cut of any job.

The person who turns up runs the business

They'll walk the plot with you, show where the leaks are and explain what to fix. The result stays honest and independent.

Less driving, quicker to come back

A tester already in the area adds minutes, not a round trip, so they can price fairly and fit a retest in sooner.

Together we can make a difference: to who does the testing, and to how well homes are built. Why we built TestConnect

In the app

Made for site work, not office software

The same account works on iPhone, Android and in your web browser. Big buttons, offline results and photos, and location shared with the site only while you're on your way, and only if you choose to.

Will it be reliable?

A test that doesn't happen holds up a plot. This is what's in place so a booked test happens, and so you know where things stand.

  • Keep the testers and assessors you useInvite them, make one preferred for a site, or keep booking through your assessor. The marketplace is there when you need cover.
  • Ready before anyone sets offBooked times, a "ready?" check the day before, an "on the way" alert and the arrival logged. Your site manager can call or text the tester.
  • Every result on recordPasses and fails, photos and certificates against each plot, and Results and performance across your sites. Nothing lost in email threads.
  • Scheme number on air testsTesters give their scheme membership number. It's self-declared, so you can check it on the scheme's public register.
  • If a tester drops out, you're toldYou get their reason, and the job reopens straight away, first to testers already passing.
  • If a job isn't taken, you're toldJobs go first to testers already passing, then more widely, step by step. If it's still open after a day, you can invite your usual testers with one tap.

Lower-carbon testing

Fewer wasted visits, and testing travel you can measure

Every plot needs a test, and the targets are getting tighter. Wasted trips and retests cost time, money and fuel. Here is what the published figures say.

Every new home

in England has needed an air pressure test since Approved Document L 2021 took effect on 15 June 2022. Testing a sample of plots is no longer enough.

About 15%

of the roughly 3,500 air tests lodged each week were retests after a fail, in an analysis of six years of ATTMA lodgements to 2021.

Lower-carbon testing, measured rather than claimed

Testers drive to every plot. Route fit gives work to testers who are already passing, plots on the same site share one visit, and readiness checks stop wasted trips. We record the miles each visit actually added against a stand-alone trip, and convert them with the UK government's conversion factors.

  • Readiness checks before anyone sets off
  • Plots batched into one visit
  • Per-site testing travel carbon report for Scope 3

How each visit is worked out

  1. Actual miles: the extra miles the visit added to the tester's day.
  2. Stand-alone miles: a return trip from the tester's base to the site.
  3. Saved: stand-alone minus actual, never below zero. Plots on one visit share one journey.
  4. kg CO2e: miles × the DESNZ 2025 factor for the tester's vehicle.

Always an estimate, with the method published. It covers testing travel only, not building materials, and we never claim anything has no climate impact.

Trust and feedback

Build tight, not test tight

A tester who fails a plot honestly is doing the job right. Nothing in TestConnect rewards a pass.

Honest results

A failed test is never deleted or overwritten. Corrections keep the earlier entry and need a reason, so the record holds up for building control.

Feedback on service

A failed test never means a bad review. Not turning up, or being unhelpful, does. Testers rate site readiness too.

Private by design

Each organisation's data is kept apart inside the database itself. Support staff can only look at your data if you allow it, and every access is logged.

Works with your accounts

Invoices and payments today, accounting sync next Coming soon

Testers already raise invoices from completed jobs and get paid by bank transfer or by card. Next, connect your accounting package once: invoices for test work go across with the right customer, sales account and VAT code, and when a payment is reconciled in your accounts, TestConnect marks the invoice paid.

  • XeroComing soon
  • QuickBooksComing soon
  • Sage AccountingComing soon
  • Edits sync both ways, and every change is kept in the invoice's history
  • "Money owed" shows who owes what, by age, and follows your accounts
  • Only test work comes across. Your other invoices stay where they are unless you choose to bring them in

Accounting sync will be on paid plans only, so it isn't part of the free trial. Xero, QuickBooks and Sage are trade marks of their respective owners. TestConnect is not affiliated with or endorsed by them.

Questions

Frequently asked

Anything else? Email support@testconnect.co.uk.

How do I join?

TestConnect is invite-only while we grow the network of local independents. Request an invite and we'll email you a code.

Is it really free for testers?

Yes. The Free plan costs nothing, has no time limit and needs no card. It covers one tester: marketplace work with route fit, results, photos and certificates, up to 15 of your own jobs a month, and as many office and finance users as you like. Pro is £5 a month per tester.

Is TestConnect free for developers and assessors?

Yes, always. Posting jobs, managing sites and plots, site manager links and dashboards cost nothing.

Who is TestConnect for?

Self-employed air tightness, sound and ventilation testers and small testing firms, typically with one to ten testers, though any testing business can use it. You keep your own business, prices and clients; we take no commission, and we're not a scheme or an employer. Together, local independents give housebuilders and assessors one place to book a reliable local tester, so you can win work that would be hard to cover on your own.

Can developers keep using their usual testers and assessors?

Yes. Invite your tester to a job, make them preferred for a site so they get first refusal, or keep booking through your assessor. If your tester isn't on TestConnect yet, it's free for them to join. The marketplace is there for when your usual people are busy.

What happens if a tester drops out?

If a tester hands a job back, the poster is told straight away, with the tester's reason, and the job reopens to other testers in the area: first to testers already passing, then more widely, step by step. If nobody has taken it after a day, the poster is told, with one tap to invite their usual testers, raise the fee or change the date.

Is TestConnect a scheme?

No. We don't audit, certify or police anyone, and we don't lodge certificates. Testers lodge with their scheme as they do now, then upload the certificate and lodgement reference so the assessor and developer can see it against the plot.

Who can test through TestConnect?

Air tightness, sound and ventilation testers. Signing up needs only a name, email, business name, base postcode and the tests you do. Where a job needs a scheme, the tester adds their membership number, which is shown to the poster as self-declared; schemes remain responsible for checking competence.

What is route fit?

For each marketplace job, TestConnect works out the cheapest place to fit it into the tester's day and shows the extra miles and minutes it adds. It uses the tester's private jobs to do this, but never shows them to anyone else.

Do site managers need an account?

No. Site managers get a secure link showing access details and plot status, and can confirm that plots are ready. They don't need to log in, and prices are never shown to them.

Who runs TestConnect?

TestConnect is built and operated by Wilgenry Software Ltd, a UK software company. Wilgenry staff can't see organisations' private information: support access needs the organisation's permission, is time-limited and is recorded.

Do office staff need a paid seat?

No. You pay for the people who test. Office administrators, finance and read-only users are free and unlimited on every plan. They can't carry out tests.

Is there a free trial?

Yes. Every new tester business gets Pro free for 60 days, for the whole team, to get a feel for it. No card needed.

What happens after the free trial?

We'll remind you 7, 3 and 1 days before it ends. To keep Pro, add a card and it's £5 a month per tester. If you do nothing, you move to the Free plan and your data is kept.

Is there an app?

Yes. TestConnect works on iPhone, Android and in your web browser, all from the same account.
