What to expect from your Colt engineer

Colt Engineers. The best in UK smoke control maintenance.

Each one of our 60 engineers have been expertly trained and accredited with one aim in mind – to keep your buildings safe and legal. Our team is so dedicated to delivering good quality service that 14 of our longest serving engineers have an average of 20 years each at Colt. That’s truly unparalleled experience.

For Colt engineers, the training never stops

As well as being fully certified to SDI 05, each one of our engineers undergoes comprehensive, initial training from our technical department upon joining. This is topped up regularly with knowledge and skills in the latest technology and regulations. Our engineers also know that a simple smoke test is not a service. In fact, many of the engineers we hire from other firms are often staggered at the sheer thoroughness of a Colt site visit.

Nationwide coverage and fast response times

Colt is the UK’s only smoke control maintenance provider big enough to offer truly nationwide coverage and regional contracts. Because of this, our engineers can be found stationed everywhere up and down the country and have an average response time of 4 hours and a guaranteed response time of 24 hours. You can count on them 24 hours a day, 365 days a year, no matter where you are.

Our engineers help you make the most of your time

We understand how valuable your time is, so once you’ve been assigned an engineer, we aim to send them to each of your site visits. They’ll know your site and its systems inside-out and send you reports of the work carried out promptly upon completion.

What to expect from a Colt engineer site visit:

Before your visit:

  • Whether you know what smoke ventilation or extract system you have, the first step towards setting up a contract with Colt is a free site survey from us to help determine what your particular requirements are. You can easily book your free site survey here.

  • After the site survey, we will produce a quote for you. This quote will include detailed information on the work we’ll carry out for you, as well as information on when we propose to do it, depending on your site’s requirements.

  • Once you’ve approved the quote, we will confirm that any fall-resistant wires on your site are still in date and tagged and that you are happy with the RAMs. After this, we will provide you with the names of your engineers and proceed to the site visit, on the scheduled date.

During your visit:

  • Our professional and courteous engineers will greet you and confirm what work they will carry out as quickly as possible, to minimise your management time. Then, they will get to work!

  • The first job will be to consult the control panel and check for faults. If the system is pneumatic, the compressor will be checked next for pressure build up, the condensate will be drained and depending on the service, will either be a safety check which will include running and stopping the compressor at the correct pressure, checking the pressure relief valve for correct operation, checking the oil level is correct and checking for wear on the fan belt.

  • Thereafter, depending on what’s needed for your particular system type, our engineers might check on oil levels, filters changes, compressor pumps, pressure switch checks and fan belt adjustments. Electrical checks will also be carried out on motor and associated controls.

  • If the system is electric in operation then the charging rates and load of any battery back-up and control systems are checked.

  • If fans are installed, motors will have a drop test, resistance test and load test, motors checked for vibrations and excessive noise on full speed running and any associated controls, differential pressure switches, variable speed drives checked and adjusted etc.

  • We then move on to the ventilators, dampers, doors controllers, fans and smoke curtains that may be installed.

  • If vents are installed in, for example, a warehouse, then access to the roof is carried out as per the RAMS, be that from a MEWP or through fixed access ladders doors hatches’ etc. While the ventilator is closed, we check for debris and external fixings on the ventilators.

  • With the ventilators in the open position, we clean out the rain channels and check for damage, check for air and water leaks on the system and the cylinder / actuator during operation to confirm the set opening and closing time.

  • Check the integrity of the fixed fusible link.

After your visit:

  • Depending on what has been found on the service, the engineer will forward a complete job sheet to the office, this will generate the following:

    • A pass certificate will be issued to you.

    • An At-Risk certificate will be issued and a report and cost of anything required to bring the system up to full operation.

    • A fail certificate will be issued with a report and cost of anything required to bring the system up to full operation.

  • If you received a pass certificate, there is no need for you to do anything else. If you receive either an ‘At Risk’ or ‘Fail’ certificate, a return visit can be ordered and completed so your system is repaired to full, legal standards.

  • On completion, you will receive a certificate issued to confirm the failed items have been repaired and the system is operational.

  • During the one-year contract you can call us anytime for emergency call outs if required.

  • Your contract renewal will be sent to you before the anniversary of your expiry date.
