Central Vacuum near you

Retrofit work follows the voids. On a suspended timber ground floor there is usually room to run tube between joists from a hallway inlet towards the outside wall, and the crawl space under a Victorian floor can be generous. Upstairs the loft is the natural run, dropping down into stud partitions or into the corner of a built-in cupboard. The hard part is almost always the vertical connection between the two, which is why a boxed corner, an airing cupboard, a redundant flue or the back of a wardrobe gets used so often.

Solid ground floors change the answer completely. Where there is no void, tube has to go up rather than down, running at high level within boxing or through the ceiling and back down into partitions, and in a bungalow with a concrete slab the loft does most of the work. None of this is impossible, but it needs to be designed before the first hole, because a system laid out room by room as the installer goes usually ends with one inlet in an unusable position.

Where the power unit lives matters as much as the tube. A garage or an outbuilding keeps the noise out of the house and makes emptying easy, but it means the tube crosses from the house into the garage, which raises a question the next section answers. A utility room is quieter to run but puts the noise inside, and a loft position is the hardest to service because you will be emptying a canister at the top of a ladder.

This is the detail that distinguishes a proper installation. If the power unit sits in an attached or integral garage, the tube has to pass through the wall or floor separating that garage from the house, and that element is required to be fire-resisting construction. Section 9 of Approved Document B Volume 1, in the 2019 edition incorporating the 2020 and 2022 amendments, states the principle: every joint, imperfect fit and opening for services through a fire-separating element should be sealed with fire-stopping so that the fire resistance of the element is not impaired.

For pipes, paragraph 9.2 offers three routes. Alternative A is a proprietary tested sealing system, which works at any pipe diameter. Alternative B allows fire-stopping around the pipe where the nominal internal diameter stays within Table 9.1, which for a wall or floor separating a dwellinghouse from an attached garage permits 160mm for high melting point metal, 110mm for lead, aluminium, fibre cement or uPVC pipes complying with BS 4514 or BS 5255, and only 40mm for any other material. Alternative C is a metal sleeve used with specified pipe materials.

Central vacuum tube is generally plastic that does not meet the specified pipe standards, and it is usually larger than 40mm, which puts most installations in the first column: a proprietary tested sealing system, correctly installed, rather than a handful of expanding foam. The same logic applies to a flat, where separating walls and floors are compartment construction, and to the enclosure around a protected stairway in a three-storey house. Ask the installer how they are sealing the penetration before it is buried.

Cordless vacuums have taken most of the ground central systems used to occupy, and it is worth being honest about that. A modern stick vacuum is grabbed and used in thirty seconds, needs no installation, costs a fraction of a ducted system and goes in the car. Against that, it holds a small amount of dust, runs for a limited time, and exhausts back into the room you are standing in.

A central system wins on three things and only three. It removes fine dust from the living space entirely when it is vented outside, which is the argument for anyone in the house with asthma or a dust allergy. It has far more sustained suction than a battery machine and does not fade as it runs. And it is quiet at the point of use, because the motor is in another room.

The sensible conclusion is that a central vacuum is worth installing when the building is already open — a refurbishment, an extension, a loft conversion or a new build — or when there is a health reason that makes the exhaust point decisive. Chasing tube through a finished, occupied house to replace a vacuum cleaner that works is a much harder case to make.

Most of the money is labour and access rather than hardware. The variables are the number of inlets and how far apart they are, the floor construction on each storey, whether there is a usable loft and crawl space, how many vertical runs are needed and whether a route already exists, whether the unit is vented outside and how far the exhaust has to travel, whether any penetration crosses fire-separating construction and needs a tested seal, and whether the work is happening in a finished house or alongside other building work. Installing during a refurbishment is a fundamentally cheaper exercise than retrofitting afterwards.

LokalMatch makes the introduction and leaves the rest to you and the installer. Describe the house, its floors and where you imagine the unit going, once, with your postcode, and installers who cover your area can respond. There is no charge to homeowners; pros pay for the requests they receive. LokalMatch does not do the installation, does not set prices and does not vet, rank or recommend the businesses that reply, so comparing what each quotation includes is part of your job.
