M&E compliance software,
built by a contractor.

A UK M&E contractor needs software that plans engineers across sites, records hours at the gate and produces the certificate at the appliance. Unibuild is bespoke business software built for that shape of firm: QR clock-in timesheets, the weekly labour planner, gas and F-Gas records, and safe isolation permits.

M&E and building services contractors running jobs in Unibuild
Your week

Your engineers are spread across a dozen sites, and you find out where they went when the timesheets come in.

Certificated work is the product. It gets produced on a pad in a van, photographed, sent by message, and typed up days later by somebody who was not there.

Monday 07:10
Two supervisors are both expecting the same engineer. Neither of them is wrong.
A day lost
In a plant room
The gas record is written on carbonless paper, in the dark, next to a boiler.
Transcribed wrong
At the counter
Materials bought on account with a job name given verbally. No order exists to check the invoice against.
Coded to guesswork
Quietly, in March
An engineer's gas or F-Gas registration expired. Nobody noticed until a client's auditor did.
Certificates in doubt
Eight months late
A test instrument went out of calibration, which puts a question mark over everything issued since.
Retesting
The client rings
They want the certificate from last September. It was definitely issued. Somewhere.
An afternoon
The common thread The record is made away from where the work was Everything else follows from that

All of it on one account, with every engineer on it and never a charge per seat.

M&E compliance software

Compliance software is judged on
what it can produce afterwards.

Unibuild does three things. It records the work where the work is, it evidences it attributably and retrievably, and it prompts before a date passes. The duty stays with the duty holder.

Recorded at the appliance
The gas safety record is created on the phone where the appliance is, domestic 46C or commercial C3C, appliance by appliance with the combustion readings, the defects, and the warning notice and warning label flags. The engineer's registration number, the issue date and the next check due date sit on the same record. There is no paper original, so there is no transcription step and no transcription error.
Evidenced with a name and a time
The four part safe isolation permit is the record that the equipment was made dead, isolated and earthed, with the specific points identified. Authorisation, acceptance, work sign off and cancellation each capture their own signature, printed name and time, and a switching schedule covers a sequenced isolation. The permit is raised on the phone before work starts and the moment it was created is stamped on it, so one completed afterwards says so.
Prompted before it lapses
Gas Safe dates, REFCOM and other accreditation certificates, test instrument calibration and every training record carry an expiry, banded onto one reminder page with a thirty day window, amber inside ninety days on the matrix and red once passed. A named person acts on each one. One case is automatic: a subcontractor whose insurance or certificate has lapsed is removed from approved status overnight, which withdraws that firm from the order forms and the labour planner. That has fired 62 times on live data.
Produced on the day
The record is a finished certificate the moment it is saved, numbered and branded, so it is handed over on site rather than after an office cycle. EIC, EICR and Minor Works Certificates are produced the same way, branded to your firm.
Found by the job, not from memory
Certificates, permits, F-Gas logbooks, photographs and engineer's reports sit against the project and the asset they belong to, with an audit trail on the document itself. When a client asks in September for something issued last year, it is retrieved by the job rather than searched for across a mailbox and a filing cabinet.
What matters most to you

Six things M&E compliance
software has to get right.

In the order an M&E business feels them: recording work where the work is, and proving competence when somebody asks.

Hours you
can rely on

An A4 poster at the site entrance carries the project QR code. The operative scans it and the QR clock-in records the clock-in against the correct job.

  • The time is recorded at the scan, not read from the phone
  • A photograph and the location captured at the clock-in
  • The day writes itself onto the timesheet
  • Projects can be set so QR is the only way in
5,204 clock-ins recordedLive

Labour planning
across sites

Employed staff, agency workers and subcontract firms on one weekly grid, published to a wall board and to every operative's phone.

  • A person can be planned onto two sites in one day
  • Approved holiday removes the allocation control entirely
  • The clock-in marker appears in the planned cell
  • The plan survives its author going on leave
Plan against actualLive

Gas and F-Gas
on the phone

The record is created at the appliance. There is no paper original, so there is no transcription step and no transcription error.

  • Domestic 46C and commercial C3C, two proper forms
  • Appliance by appliance, with combustion readings
  • Engineer and recipient both sign on the screen
  • F-Gas logbook and leak checks against the asset
Certificate before the van movesLive

Safe isolation
permits

The four part permit your engineers will recognise immediately as the real thing rather than a generic form with a signature box.

  • Points of isolation and earthing identified
  • Switching schedules for sequenced isolations
  • Two parties sign, each with a printed name and date
  • Cancellation is a signed act with a time on it
Electricity at WorkLive

Spend
control

No purchase without an order, and no order without a named person approving it. Raised at the merchant's counter, decided in under a minute.

  • Push notification opens the approval screen itself
  • The order number is only issued on approval
  • Invoices upload against the order that carries the job
  • Own card purchases raise the reimbursement automatically
879 orders in five monthsLive

Competence
evidence

Every card, ticket and course your people hold, in a grid that colours itself red when something has expired.

  • Sixteen qualification columns, thirty-nine e-learning courses
  • Amber inside ninety days, red once passed
  • One A3 landscape page for the pre-start meeting
  • The certificate file attached to the record
Handed to a main contractorLive
One engineer, one day

Nothing in this day was
typed up afterwards.

A working Tuesday for a service engineer on a commercial contract, following the information rather than the software.

07:12On site

He scans the poster on the welfare unit door.

The project comes from the code, so there is no job number to remember. The time is recorded at the scan, the phone takes a photograph, and the location is recorded with it. His day on the timesheet now exists.

Timesheets and QR clock-in
08:40Plant room

Isolation is authorised before he touches anything.

The permit names the points of isolation, the points of earthing and where the danger signs went. The authorising person signs, he signs to accept, and the validity window granted is shorter than the one he asked for, which is recorded on the document.

Permits to work
10:25At the appliance

The gas record is completed appliance by appliance.

Operating pressure, safety device operation, spillage test, flue flow, initial and final combustion analyser readings, ventilation and termination. He signs, the responsible person signs, and the numbered A4 certificate exists from that moment.

Gas safety records
11:50Merchant's counter

He raises the purchase request from the queue.

Supplier, project, value, VAT treatment and a photograph of the quote. Every member of the approval committee is pushed a notification that opens directly on the order. He is at the counter for four minutes rather than forty.

Purchase orders
15:05Second site

He writes the engineer's report where he found the fault.

What he found, what he did about it, photographs of the condition on arrival, and the client's signature on the screen. Three months later, when responsibility for that damage is disputed, there is a dated document rather than a conversation.

Engineer reports
16:48Off site

He clocks out, and the week builds itself.

Both times and both locations are on the timesheet for the day. On Friday a supervisor reviews a week that is already there, already against the right jobs and already priced at each person's dated cost rate. Nobody types anything.

The regimes you live under

Certificated work carries criminal liability, so the record has to stand up.

Unibuild records, evidences and prompts.
The record is attributable, retrievable
and ready when it is asked for.

Gas Safety (Installation and Use) Regulations 1998
The landlord's annual check and record under regulation 36, captured appliance by appliance with the defects, the warning notice and warning label flags, the engineer's registration number, the issue date and the next check due date. The record is a finished certificate the moment it is saved, so it can be handed over on the day rather than after an office cycle.
Gas Safe registration
The registration number is recorded on the certificate exactly as the engineer enters it, and the record is tied to that engineer's own account. The training matrix separately holds a Gas Safe date per member of staff. For a gas heavy business, that is connected to the Gas Safe Register, so an expired registration warns the office.
Retained UK F-Gas Regulation
Refrigerant type, charge weight, GWP and the calculated carbon dioxide equivalent held per asset, with a dated logbook of work and gas added, and leak check records carrying the engineer, the ACRIB card number, the test type, the result and the next test date. It prints as a REFCOM presented record log book. You set the leak check frequency band, and the register carries the due dates forward.
Electricity at Work Regulations 1989
Regulations 12, 13 and 14. The permit is the record that the equipment was made dead, isolated and earthed, with the specific points identified, and the lone working permit prints an explicit prohibition on live electrical work when working alone.
BS 7671
EIC, EICR and Minor Works Certificates are produced in the platform, branded to your firm, alongside electrical and mechanical installation sign off and the company handover document: ten questions covering permissions, isolation, cable support and document handover. Around each certificate sits the rest of the job, the labour, the client and the site it belongs to.
Calibration traceability
Every instrument with its serial number, its holder and its calibration expiry, warned thirty days out. Each test record is linked to the instrument that produced it, set up with your forms.
PUWER 1998
Work equipment suitable and maintained. Every power tool is an individual record with its PAT history, its service history and its hand arm vibration magnitude, reachable by scanning the label on the tool itself.
Working Time Regulations 1998
Start and finish times per day per person per project, held over an unbroken history with a full change log. The platform holds the hours the 48 hour average is calculated from.
Questions from your sector

Asked by M&E and
building services firms.

Is Unibuild compliance software for M&E contractors on major building projects?
Yes, for M&E firms of 5 to 300 people working on major projects. On a major project the record is asked for months later, by the principal contractor, the client or an auditor, so it has to come off the job itself. Unibuild holds the training matrix for every engineer and the gas, F-Gas and electrical certificates produced on site, in compliance and certification. The documents and certificates it issues go out on your letterhead and stay against the project. Users are unlimited, so every engineer, supervisor and subcontractor is on the record, and your clients read their own projects in the client portal. See it on your own kind of project: book a 30-minute demo.
Is Unibuild compliance software for M&E contractors managing multiple certifications?
Yes. An M&E firm carries several registers at once: Gas Safe and REFCOM dates per engineer, calibration on every test instrument, CSCS and trade cards, and its own accreditations and insurances. Each is held with its expiry on the training matrix or in compliance and certification, banded onto one reminder page with a thirty day window. A named person acts on each one before it lapses. The certificates the work produces, EIC, EICR, Minor Works, gas safety records and F-Gas logbooks, are produced in the platform on your letterhead and found by the job. Book a 30-minute demo to see the registers on live data.
How do mid-sized M&E contractors manage Part P and EICR compliance across teams?
Part P of the Building Regulations covers electrical safety in dwellings in England and Wales. Notifiable work is either carried out by an installer registered with a competent person scheme, who certifies it, or notified to a building control body (Approved Document P). An EICR is the periodic inspection and test report under BS 7671, the IET Wiring Regulations. Privately rented homes in England need one at least every five years under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. Across a team that is a competence question first. The training matrix holds each engineer's BS 7671 qualification, inspection and testing qualification and scheme registration, each with its date, so the planner sees who can sign a report. EIC, EICR and Minor Works Certificates are produced in compliance and certification on your letterhead, numbered and found by the job, and your client reads them in the portal. Book a 30-minute demo and ask to see an EICR produced on the day.
Can engineers complete gas and F-Gas records at the appliance?
Yes. The gas safety record is created on the phone at the appliance, domestic 46C or commercial C3C, appliance by appliance with the combustion readings and the defects. The engineer and the recipient sign on the screen, and the numbered certificate exists from that moment. F-Gas leak checks are recorded at the unit against the asset, with photographs, and print as a REFCOM presented log book your client can read in their portal.
Can we produce electrical certificates in it?
Yes. EIC, EICR and Minor Works Certificates are produced in the platform, branded to your firm, alongside installation sign-off and handover records. Around each certificate sits the rest of the job: the labour, the client and site, the asset, the safe isolation permit, the test instrument and its calibration status. The certificate and the evidence behind it live in one place. See compliance and certification.
Does it check that our engineers' registrations are current?
Yes. The training matrix holds a Gas Safe date against every member of staff and colours it red once it passes. The registration number is recorded on the certificate as the engineer enters it, and CSCS cards are verified. Where you want it, the matrix is connected to the certificate, so an out of date registration warns the office or blocks issue.
Our engineers keep their own instruments. Can we still prove calibration?
Yes. The calibration register holds each instrument with its serial number, the engineer holding it and its calibration expiry, warned thirty days out. Each test record is linked to the instrument that produced it, set up with your forms. The first pass is a stocktake: every instrument, its serial number, who has it and what its certificate says.
Can we plan engineers across several sites?
Yes. Employed staff, agency workers and subcontract firms sit on one weekly grid, published to a wall board and to every operative's phone. A person can be planned onto two sites in one day, and the clock-in marker appears in the planned cell, so plan and actual sit side by side. See the labour run.
How do we stop materials being bought with no order?
The order has to exist before the money is committed. An unapproved order has no number and prints as pending approval, so it is no use for buying anything. Only named approvers can approve, on the phone as well as at a desk, and the push notification opens the approval screen itself. Travel orders and purchases already paid are approved automatically, and they stand out because the approver column is empty. That can be tightened if your controls require every pound sanctioned in advance.
Will my engineers actually use the app?
They already do, in the businesses Unibuild was built for. There are 5,204 clock-in records and 6,643 timesheet lines in one deployment alone, every clock-in from an operative scanning a printed code on site. The app is how they record their hours, so there is a direct personal reason to open it, and a PIN rather than a password means it takes seconds. It is also your app, published on the App Store and Google Play under your company's own name and icon.
Does the app work in a plant room with no signal?
Yes. The field app works on sites without coverage, and what is recorded there syncs with the office the moment the phone is back in signal. Clock-ins are stored on the phone and sent on automatically.
Can we keep the certification software from our scheme?
Yes. Unibuild produces EIC, EICR and Minor Works Certificates branded to your firm, and a certificate raised in scheme software has a controlled home here too. Around it sits the job it belongs to, the labour, the materials, the permits, the photographs and the handover sign-off, all against one project.
What software is best for a UK M&E contractor?
Software that holds the engineer, the hours, the certificate and the spend on one job record, because that is where an M&E firm's margin and liability sit. Unibuild is bespoke business software for UK M&E and building services contractors: QR clock-in, the labour planner, gas, F-Gas and electrical certificates, safe isolation permits and purchase orders. It is a platform in daily production since 2016, shaped to the way each firm already works. When a firm needs something new, Unibuild builds it, and changes asked for after go-live are included in the monthly fee. See how bespoke software is built from a working platform.
