A gas boiler heats water using gas then sends this heated water through a system of pipes throughout your home. This then heats systems like radiators, baseboards, and radiant heating to keep your home warm and comfortable.

Power flushing involves using a high-pressure machine to push water with cleaning chemicals through your central heating system. This process helps dislodge blockages, remove sludge, and overall clean your system.
While the chemicals work on clearing the system, the dirty water is purged, and clean water replaces it. Once the power flushing is complete, your system should have improved circulation and operate efficiently.
We utilise modern, industry-standard equipment and high-performance chemicals for power flushing. This ensures an effective flushing service that leaves your heating system pristine.
Our experienced team of professionals will deliver the service quickly and efficiently, minimizing disruption and restoring your central heating system to its optimal state.
Private landlords must obtain a satisfactory electrical certificate to ensure the safety of their tenants during their tenancy. To get an electrical certificate, it is necessary to hire a qualified and competent engineer, preferably from a company associated with a governing body such as the NICEIC (National Inspection Council for Electrical Installation Contracting). Registered engineers undergo annual inspections to maintain high standards.
Electrical certificates, also known as EICRs (Electrical Installation Condition Reports), compare your installation to current electrical standards. In the UK, these standards are defined in BS7671, commonly referred to as “the regs,” which outline the requirements for electrical installations.
During the assessment, the engineer will inspect the consumer unit (fuse box) and all electrical accessories connected to the system, including cooker sockets, available sockets, and light points.
The process of obtaining an electrical certificate involves three inspections. The first is a visual examination of the consumer unit and connected accessories. The second is a dead test, which assesses cable conditions and takes readings while the installation is not powered. The final inspection includes live testing and functional testing of circuits and RCDs (Residual Current Devices).

Gas Safety Certificates
What is a Gas Safety Certificate?
A Gas Safety Certificate, commonly known as a landlord’s gas safety record or CP12, is required for all rental properties with fuel-burning appliances and tests that the gas appliances in the property have been inspected in accordance with UK law.
In order to obtain a gas certificate, it is necessary to hire a Gas Safe Registered Engineer to inspect all the appliances in the property and confirm that they are safe for use and not at risk of gas or carbon monoxide leaks.

Boiler Installation Service
What Does A Boiler Service Include?
During an annual boiler service, an engineer will inspect the appliance and provide a report on any necessary repairs or faults.
The inspection will include a visual check for issues such as water leaks, damage to the boiler or its electrical components, poor installation, and hazards from combustible materials.
The engineer will also test the boiler’s efficiency, including a gas rate check, a flue gas analysis, and a boiler tightness test.
Safety checks will also be carried out, including stability, combustion, and case seal checks, as well as checks on air vents, flues, and chimneys.
The engineer will also analyze the system pressure across different points to ensure the boiler is operating at the correct pressure.
Why is it important
Regular servicing helps maintain the proper functioning of your boiler, reducing the likelihood of heating and hot water loss and minimizing the risks of gas leaks. A well-maintained boiler also ensures energy efficiency, saving you money.
