fan INSTALLATION DERBY

The cost varies depending on your property size, the number of cameras or sensors you need, and the type of system you choose. A basic home alarm system might start from around £400-£600 installed, while a comprehensive CCTV setup with multiple cameras typically ranges from £800-£2,000+. Commercial installations vary more widely based on coverage requirements. We provide free surveys and detailed quotes with no hidden costs, so you'll know exactly what you're paying before we start any work. We only recommend what you actually need – we won't try to oversell you features you don't require.

Most bathroom extractor fan installations take 2-3 hours to complete. This includes running the cable from your lighting circuit, cutting through the external wall (if needed), fitting the fan unit, installing the external vent cover, and testing everything works properly. If we're replacing an existing fan in the same location, it's usually quicker – around 1-2 hours. We always aim to minimize disruption and leave your bathroom clean and tidy when we're done.

For replacement fans in the same location, Building Regulations approval typically isn't required. However, new installations – particularly bathroom and kitchen extractors – must comply with Building Regulations Part F (ventilation) and Part P (electrical safety). As registered electricians, we can self-certify our electrical work, which means you don't need to involve Building Control separately. We'll provide you with the necessary electrical installation certificate, which is important for your insurance and future property sales.

The most common reasons extractor fans stop working include: motor failure (especially in fans over 10 years old), blown capacitors, seized bearings due to dust accumulation, or electrical supply issues like a tripped circuit breaker or faulty wiring. Sometimes the fan appears not to work because the switch has failed rather than the fan itself. We can diagnose the exact problem quickly and let you know whether repair or replacement is the most cost-effective solution. In many cases, we carry the necessary parts to fix it on the first visit.

Yes, absolutely. We regularly install ceiling fans in rooms that don't currently have ceiling wiring. We'll run a new cable from your consumer unit (fuse box) to the ceiling location, install appropriate switching (wall switch, pull cord, or remote control), and fit the fan securely. This does involve lifting some floorboards in the room above or working from the loft space, but we'll discuss the exact approach during our assessment. The job typically takes 3-4 hours and includes all necessary electrical certification.

Extractor fans are rated in cubic metres per hour (m³/h) or litres per second (l/s). Building Regulations require bathrooms to have extraction rates of at least 15 l/s (54 m³/h) for mechanical ventilation. However, the right size depends on your bathroom's volume and usage. A small bathroom might only need a 100 m³/h fan, while larger bathrooms or those with showers need 150-200 m³/h or more. When we visit, we'll assess your bathroom size and recommend the appropriate fan capacity. If your current fan isn't coping with condensation, you likely need a more powerful model or one with humidity-sensing technology.

Standard extractor fans are fitted directly in the wall or ceiling where you want to extract air. They're visible in the room and typically work well for straightforward installations. Inline fans are fitted within the ductwork (usually in the loft space) and connected to a grille in your bathroom or kitchen via ducting. They're more powerful, much quieter in the room (since the motor is remote), and better for situations where you need to duct air over longer distances. Inline fans are particularly good if you have multiple extraction points or your bathroom is far from an external wall. We'll recommend the best option based on your specific situation.

Yes, ceiling fans can improve heating efficiency during winter months. Most ceiling fans have a reverse function that pushes warm air (which naturally rises) back down into the living space. This can help distribute heat more evenly and potentially reduce your heating costs by making the room feel warmer without increasing the thermostat. In summer, running the fan in the standard direction creates a cooling breeze effect. While ceiling fans use very little electricity (typically 15-75 watts), they can make rooms feel 3-4 degrees cooler through air circulation, reducing reliance on air conditioning or allowing you to use less heating.
