Smoke Ventilation Finance

Q: Can smoke ventilation finance cover the vents, actuators and control panel together?

Yes, most lenders will include the vent units, actuators, control panel and cabling on the same agreement, provided it's all itemised on the installer's invoice. Bundling the whole package is the norm, since the components only function as a complete system. Your broker can talk this through against your own trading history and site circumstances before you commit to a particular structure.

Q: Is smoke ventilation typically financed by the developer or the eventual building occupier?

It depends on the project. On a new build or major refurbishment, the developer often funds the AOV system as part of the wider construction finance, while on an existing building it's more commonly the landlord or occupying business responding to a building control or fire strategy requirement who arranges finance directly. Your broker can talk this through against your own trading history and site circumstances before you commit to a particular structure.

Q: Does finance cover ongoing testing and maintenance?

No, not usually. AOV systems require periodic testing to remain compliant and reliable, and this is a running cost, similar to a maintenance contract, that sits outside the finance agreement for the equipment itself. Budget for testing and maintenance separately when comparing quotes. It's worth asking your supplier for an invoice that clearly separates the equipment being financed from any ongoing subscription or service charge, so there's no ambiguity when the finance agreement is drawn up.

Q: Is a smoke ventilation system eligible for Annual Investment Allowance?

Yes, a smoke ventilation system qualifies as plant and machinery, so it's eligible for AIA up to the current annual limit under Hire Purchase. Leased systems don't attract AIA directly, but the rental is usually deductible as a business expense instead. Confirm the treatment with your accountant before committing to a structure. Because AIA is a single annual limit across all your capital purchases, it's worth checking the timing of this purchase against anything else you're planning to buy or finance in the same tax year, particularly if several items are being bought together.

Automatic Opening Vent (AOV) smoke ventilation systems cost from around £2,400 for a pre-configured staircase package to £30,000+ for a multi-vent system covering several escape routes in a larger building.

Can you finance a smoke ventilation?

Yes, smoke ventilations are financed as a standard asset purchase, usually on hire purchase or a lease, with the machine itself acting as the security. UK prices typically run £2,400 to £30,000, and most deals are written over 24-60 months with a deposit of around 10-20%. Decisions typically take 24–48 hours. Used machines are financeable too, usually with a shorter term.

What buyers actually specify

Guide prices for sizing a finance agreement, not quotes. Manufacturers in this market mostly price on application, so where a current UK list price could not be confirmed the row describes a specification class rather than naming a model. Your supplier quote is what the agreement is written against.

Machine or specification	Guide price	Type
Single AOV vent unit with actuator	£83 - £3,600 (component, ex VAT)	AOV Vent Unit
Pre-configured staircase AOV package	£2,400 - £2,970	Complete AOV Package
Multi-vent smoke ventilation system (several escape routes)	£10,000 - £30,000	Complete Smoke Ventilation System

Tax benefits

A smoke ventilation system is treated as plant and machinery for tax purposes, so it qualifies for the Annual Investment Allowance (AIA), letting a business deduct the full cost from taxable profits in the year of purchase, up to the current £1,000,000 annual limit. Companies buying new, unused equipment may also qualify for full expensing, a 100% first-year deduction against Corporation Tax. These allowances apply where you own the asset, so they are available under a Hire Purchase agreement. Under a Finance Lease or Operating Lease you do not own the system outright, so allowances are not claimed directly; instead the payments are generally deducted as a business expense against profits. Always confirm treatment with your accountant before committing to a structure.

Market context

Smoke ventilation systems are installed to clear smoke from stairwells and escape routes so a building meets its fire strategy, so the buyer is usually a developer, landlord or facilities manager responding to building control requirements on a new build or refurbishment rather than a discretionary purchase. Like other fixed fire safety equipment, the vents, actuators and control panel become part of the building fabric once installed, so financing is generally assessed against the supply-and-install invoice rather than the system's standalone resale value. Maintenance and periodic testing are an ongoing running cost separate from the finance agreement, and replacement is usually driven by a control panel or actuator reaching the end of its service life rather than the vents themselves failing.
