Landlord Gas Safety Certificates


For rented properties it is the Landlord's responsibility to ensure it is gas safe and they must be able to provide their tenants with an up-to-date Gas Safety Certificate to show that boilers and gas appliances have had an annual gas safety check by a Gas Safe registered engineer.


It is also a legal requirement that Landlords have all gas appliances serviced regularly, usually annually by a Gas Safe registered engineer.


Our Gas Safe registered engineers are fully qualified and experienced to carry out Gas Safety checks and services on gas appliances and will issue landlords with a Gas Safety Certificate on completion of the job.



Electrical installation certificates


All electrical installations are required to be tested regularly to the standards defined by the IEE Wiring Regulations (BS 7671). Depending on the type of building Periodic Inspection and Testing of your electrical installations should be carried out at regular intervals. The frequency of these tests are in line with the type of installation, its use and operation, the frequency type of electrical installation, its use and any maintenance.

For example a domestic home only needs to be tested at a maximum of every ten years or at a change of occupancy whereas a Swimming Pool should be tested every year. Buildings such as Offices should be tested every 5 years and shops and retail premises should be tested at a maximum of every 3 years.

If your building is rented out then it is important to carry out more regular testing as any damage caused by moving or DIY work could affect the safety of the building. If your home or property has not been properly tested it could affect your insurance.

Faulty or loose wiring could cause fire and damage your property.

It is not possible or practical to inspect all parts of an electrical installation; therefore Control System Installation will agree a sampling process before starting the testing.  This sample is usually about 5%-10% of all accessories, control equipment and fittings.


To test the circuits we will need to switch off the electrical system for a lot of the time, however if this is a problem we can arrange a convenient time to come and do the testing that will not affect your business or lifestyle too much. Before we start the test we will agree the amount of down time that is acceptable with you then arrange a schedule for switching off, this will either be all of the electrics or we can arrange individual distribution boards and areas to be switched off at particular times to make the testing more convenient for you.




Periodic Inspection Reports


Periodic inspection reports suitable for landlords and homeowners

At CSI we can offer a same day service to assist with urgent inspections, and to assist with the process of moving into a new home / moving new clients. All our engineers have the latest 17th Edition 2011 wiring regulations test and inspection certification, they also carry a fully calibrated test and tool kit. We can also contact any tenants or letting agents for access, collect keys from estate agents or arrange a suitable time at your convenience.

Our periodic test inspections include a full inspection and testing of the fixed wiring of a property including:

  • Earth bonding to gas and water
  • Correct consumer unit
  • Damage to cables, sockets, switches etc
  • Full instrument test of the circuits
  • A 3 page report will be compiled using the Fast Test Software


Any faults will be flagged up on page 2 of the report and listed with a priority rating between 1 and 4. These figures refer to the following status:

  • Requires urgent attention
  • Require improvement
  • Requires further investigation
  • Does not comply with BS7671: 2011 (as amended)


A quotation for any remedial works will be provided with the report along with the VAT receipt for the inspection. Reports can be e-mailed to multiple precipitants if required to assist the process of moving home or new tenants.


The 17th Edition Wiring Regulations BS7671 – 2011 is the latest edition of the IEE British Standard publications. Every electrician we employ has trained to the IEE regulations and attended refresher courses to bring their expertise up to the latest 2011 edition.

Our teams of engineers have also a minimum of 5 years on-site experience to be able to work for CSI (2391) and to carry out Periodic Electrical Inspections in the UK, the engineers require alongside the BS7671 to have also passed a City and Guilds Level 3 certificate in inspection, testing and certification of electrical installations (2391). This training provides the engineer with the relevant information and procedures regarding an initial visual inspection, verification and certification. This includes collecting data of correct types of cable, fuses – MCBs etc, the presence and correct operation of an RCD trip switch to prevent harm to property and lives from fire and electric shock. The presence and correct size of Earthing conductors into the property, to the mains gas and water supply, to any exposed metal parts that may need earth bonding.


Test includes and not limited to an instrumental verification test by the following equipment:

  • Testing the voltage with a V tester
  • Test to measure continuity to calculate ohms
  • Test the insulation resistance to determine M ohms
  • Test the earth loop impedance to determine ohms
  • Test RCD to calculate mS

A full analysis on the supply of your house/business premises to BS7671 IEE Wiring Regulations including consumer unit, earthing arrangements, wiring, fixtures and fittings (i.e. lights, sockets, switches) installation methods, loose connections and many more. The following tests are carried out:

  • Installation resistance
  • Earth loop impedance – to verify path of earth
  • The continuity of earth conductor
  • The continuity of ring final conductor
  • Check the Polarity
  • RCD test to check tripping times and mA settings

The procedure to test the consumer unit includes taking measurement of a range of different points around the property. Visual inspection will be used as well as instrumental test. To ensure a good supply is present earth is tested.  These tests are called Ze and Prospective Short Circuit. The above tests can verify a circuit has continued earth path to each fitting and more importantly the RCD operates within the specified current and time. Please feel free to contact us for any further details as we can help with any questions you may have in regard of the technical aspect of these tests.



Energy Performance Certificates


From 1st October 2008, landlords are required to provide Energy Performance Certificates (EPCs) for their properties.

The requirement is introduced by the Energy Performance of Buildings Regulations 2007 and means that landlords and tenants will have more information about how energy efficient their property is.

A landlord will need to provide an EPC to a prospective tenant and any new tenant who moves into their property after 1st October 2008 (this does not apply to tenants who have been living at a property before this date whilst they continue to live at the same property) free of charge


Part P Certificates


In January 2005, Part P of the Building Regulations came into force in the UK. These regulations are to introduce safety standards to electrical installations within domestic properties.

This basically means that, with few exceptions any electrical work undertaken in your home such as a new electrical circuit or any work in your kitchen, bathroom or garden must be notified to your Local council Authority Building Control for inspection.


By using a contractor who is registered as part P with a government approved body the contractor will be able to self-certify that the work meets the required regulations and that it has been notified to your local authority.




Fire Detection and Alarm System Certificates


The Regulatory Reform (Fire Safety) Order 2005 applies to all commercial and domestic premises as well as to any place the public reside in or visit. This requires employers to undertake a comprehensive fire risk assessment. A designated member of staff must be made responsible for Health and Safety and accountable for the servicing of fire alarms, and for ensuring that, where fitted, any fire protection equipment is maintained to the relevant standard. This all with proper records being maintained and logged.

If you are concerned about the condition of the fire alarms in your workplace and need professional advice, please call us.



Emergency Lighting completion Certificates

Testing and Maintenance

The minimum testing and provision of emergency lighting is detailed in BS EN 50172:2004/ BS 5266–8:2004 Emergency escape lighting systems, and requires that adequate facilities are provided for testing and should be incorporated into the system design.

It is important that staff carrying out the tests is of a high enough caliber and reliability and that discharge tests are performed outside of normal working hours or phased for permanently occupied buildings so that emergency lights are tested alternately.

Testing requirements include: a monthly Function test by breaking the supply to them to see if they work, then restoring the supply to check charging indicators and an annual Discharge test where lights are tested for their full rated duration period then checked after supply is restored. Results should be recorded.

If tests are to be carried out manually then a separate switch is required for each circuit, unless the whole building is to be switched off and will probably warrant two building checks, first to see if the lights are operating and second to ensure they are recharging.

If each light is switched individually then only one walk round the building will be needed however separate switches can look unsightly and must be designed so they cannot be interfered with.

Emergency lighting systems should be serviced regularly, usually whilst carrying out tests, and any spares likely to be needed, e.g. replacement lamps should be readily available at all time.



Commercial Gas Installation Safety Certificates


Gas Safety is crucial in any business or home environment but is particularly important in a commercial catering environment, ensuring the safety of both staff and patrons alike.

The Control System Installation  recommend a full gas safety inspection to ensure that your gas installation and appliances comply with current legislation and are in full working order Control System Installation commercial gas inspection includes a detailed report of your commercial premises including your essential annual gas safety certificate.


Commissioning of water Pipework Certificates

In accordance with BS 6700 , relevant Water Regulations and Building Regulations require that domestic hot ,cold water and waste pipe-work system, installing or replacing need to be inspected, tested, commissioned and certified before they are connected to mains water and drain services.



Portable Appliance Testing Certificates


Who is Responsible


The Provision and Use of Work Equipment Regulations 1998 (PUWER) requires, every employer to ensure that work equipment is suitable for the purpose for which it is provided, only used in the place and under the provisions for which it is provided. It also requires every employer to ensure work equipment be efficiently maintained and kept fit and suitable for its intended purpose. It must not be allowed to deteriorate in function or performance to such a level that it puts people at risk. This means that regular, routine and planned maintenance regimes must be considered if hazardous problems can arise.

Regulation 3 of the Electricity at Work Regulations 1989 recognises a responsibility that employers and many employees have for electrical systems.

"It shall be the duty of every employer and self employed person to comply with the provisions of the Regulations as far as they relate to matters which are within his control.


It shall be the duty of every employee while at work:



  • To co-operate with his employer so far as is necessary to enable and duty placed on that employer by the provision of the Regulations to be complied with: and
  • To comply with the provision of these regulations in so far as they relate to matters which are within his control. "

Combined Pressure Test Report


A Pressure Test is a way in which leaks can be found in pressure vessels such as pipelines and plumbing. The test involves placing water, which is often dyed for visibility in the pipe or vessel at the required pressure to ensure that it will not leak or be damaged. It is the most common method employed for testing pipes and vessels. Using this test helps maintain safety standards and durability of a vessel over time.

Newly manufactured pieces are initially qualified using the hydrostatic test. They are then continually re-qualified at regular intervals using the proof pressure test which is also called the modified hydrostatic test. Hydrostatic testing is also a way in which a gas pressure vessel, such as a gas cylinder or a boiler, is checked for leaks or flaws. Testing is very important because such containers can explode if they fail when containing compressed gas.
