Built and tested on a working contractor's own jobs. Launching soon: join the waiting list.

Why it works on site

Works with no signal

Basements, risers and plant rooms. It saves on the phone and sends later.

Filled in for you

Addresses, appliances and past records carried over from the site's history.

Signed on the spot

Customers, tenants and the team sign on the phone, on site.

Filed for the office

Every PDF lands against the job and the site, ready to send on.

What's in it

One app for the whole job.

From the diary to the signed certificate. Everything shares the same jobs, customers and sites, so nothing gets typed twice.

Job sheets and certificates

The right form for the job opens on the phone, filled in from the site's history. Add readings and photos, get it signed, and the PDF is filed for the office.

The office view

A proper screen for the office: diary, customers, records and to-dos.

How it works

Three steps. Nothing typed twice.

  1. Book it

    The office books the job in the diary. It's on the engineer's phone straight away, with the address, the PO number and the site's history.

    In the office
  2. Do it

    On site, the right forms open already filled in. Readings, photos and signatures go in on the phone, signal or not.

    On site
  3. File it

    Back in signal, it sends itself. The office has the PDF against the job and the site, and the customer can have their copy.

Works with no signal

Made for plant rooms and basements.

The jobs, the site details, the forms and the tools all live on the phone. Finish a certificate with no signal and it waits in the outbox, then sends itself when the phone finds a signal.

  • Drafts saved as you go, so nothing is lost
  • The outbox sends on its own, no button to remember
  • Only what's needed stays on the phone, cleared once the office has it

For the office

And a proper screen for the office.

The same records on a computer, so whoever runs the office can see the whole firm at a glance.

  • Everyone's diary by day, week, month or person
  • Add a job and it's on the right engineer's phone
  • Every record filed against the job and the site
  • A to-do list when materials need ordering or a timesheet needs signing

Three versions

Start small. Grow into it.

The same app at every size. Move up a version and nothing changes for the engineers.

Made on the tools, not in a meeting room.

Site Simple started life as the app a plumbing and heating firm made for its own engineers and its own office. It's built and tested on that firm's jobs before it goes to anyone else, so every screen has to earn its place on a real working day.

  • Boiler services and landlord records
  • Cylinders, leaks and pressure tests
  • Plant rooms and commercial gas
  • Site work with RAMS and permits

See it for yourself

See it on a real job.

We'll take you through a job from the diary to the filed certificate, on a phone and on the office screen, using your kind of work.

  • A walk-through, at your yard or on a video call
  • Bring your awkward jobs and forms
  • No sales patter, no obligation

Fair questions

Does it really work with no signal?

Yes. The jobs, the site details, the forms and the tools are on the phone. Anything you finish waits in the outbox and sends itself when there's signal again.

Which trades is it for?

Plumbing and heating first, including domestic and commercial gas. Electrical comes next, then ventilation, sprinklers and water treatment.

Do we need new phones?

No. It runs on the phones your team already has, iPhone or Android, and the office uses it on any computer.

How do customers get their certificates?

Send their copy from the phone when the job's done. The office also has the PDF filed against the job and the site.

How much will it cost?

Prices are being set now. Join the waiting list and you'll hear first.

Who's behind it?

A plumbing and heating contractor that built it for its own engineers first, and still uses it on its own jobs.
