The free app for air testers

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.

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

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.

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

There isn't one hiding in the small print. If you want more than the Free plan gives you, Pro is £5 a month per tester. We don't take a commission on your work, and we don't sell your data.

Running TestConnect isn't free: servers, secure storage for years of your photos and certificates, and support all cost money. We charge £5 a month per tester to cover those costs, not to make a profit.

No, we're not a scheme. We don't audit, certify or police anyone, and we don't lodge for you. You lodge with your scheme exactly as you do now, then upload the certificate and lodgement reference against the plot so the assessor or developer can see it.

No. To sign up we ask for your name, email, business name, base postcode and which tests you do. No ID and no documents. If a marketplace job needs a scheme, such as an air test, you add your scheme membership number because the certificate and lodgement need it, and posters see it marked as self-declared. Calibration dates are optional and only there to remind you. Insurance details are optional too.

Only people in your own organisation. Your private jobs, clients and prices are invisible to everyone else, including assessors, other testers and us. Route fit uses your private jobs to work out the extra driving, but never shows them. Our support staff can only look if you give permission, for a limited time, and every look is logged.

No. Feedback is about your service: turning up when agreed, communication, professionalism and report quality. It's never about the result. The forms don't ask how the test went, and comments about a fail are removed if reported. You can reply to any comment, and you rate sites too.

Yes, if you're busy or can't make it. From a job you've accepted, find another local tester who has chosen to be listed for this kind of work, offer it to one or several (the first to accept takes it) and agree the fee between you. They attend as your business unless you choose otherwise, and your client still sees you: you stay responsible, invoice your client as usual, and the other tester invoices you. They never see your client's price. You can take the job back before they set off. No commission and no extra seat. To be found for this work yourself, switch on "Other testers can find me for subcontract work" in Tester profile → Subcontract work; it's off until you do.

No. It's there if you want it, and you can use TestConnect just for your own work. Nothing happens if you ignore or turn down a job.

Yes. Jobs you've opened are saved on your phone, so you can see the details and enter results, photos and notes with no signal. They upload when you're back in signal, and you can see what's still waiting.
