Can you finance a building management system?

Yes, building management systems 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 £8,000 to £400,000, and most deals are written over 12–84 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.

Tax benefits

Building management system hardware and installation generally qualifies as plant and machinery for capital allowances, so a business can typically set some or all of the cost against taxable profits through the Annual Investment Allowance or other first-year reliefs, subject to your total qualifying spend for the year. Confirm current treatment with your accountant before finalising the finance structure.

Market context

A BMS controls and coordinates a building's heating, cooling, ventilation and lighting rather than generating or saving energy directly itself, so the typical buyer is a business with existing plant, often several separate systems installed at different times, that isn't being run efficiently because it isn't centrally controlled or scheduled. The investment case usually rests on eliminating waste, such as heating and cooling running against each other, or lighting and ventilation running in unoccupied areas, rather than a fixed percentage saving, and the achievable saving depends heavily on how inefficiently the building is currently being run, which a controls specialist can usually assess from your existing energy data.

Bad credit?

Several of our 200+ lenders specialise in businesses with imperfect credit histories. You may need a larger deposit or personal guarantee, but options exist. Checking your options here does not affect your credit score, because we do not run a credit search to match you. A lender will run their own checks only if you decide to apply.

Frequently asked questions

What's the difference between a BMS and simple thermostats or timers?
A BMS centrally coordinates multiple building systems, heating, cooling, ventilation, lighting, often across several zones or an entire site, using schedules, sensors and sometimes remote monitoring, rather than each system being controlled independently. This coordination is what allows it to prevent common inefficiencies like heating and cooling fighting each other, or plant running outside occupied hours, which simple standalone thermostats and timers generally can't detect or correct.
Can a BMS be retrofitted to an older building?
In most cases yes, though the scope and cost depend on what controls and sensors already exist and how much of the existing plant needs new interfaces to communicate with the system. A survey by a controls specialist will identify what can be integrated as-is and what needs upgrading, and that survey typically forms the basis of the finance quote rather than a generic per-building estimate.
How is the energy saving from a BMS actually achieved?
Mainly by removing waste that's invisible without central control and monitoring: plant running when a space is unoccupied, heating and cooling systems working against each other, or equipment left on schedules that no longer match how the building is actually used. Because the scale of that waste varies enormously by building, a specialist assessment of your current energy data is the right way to estimate the achievable saving rather than a generic industry figure.
What deposit is needed for BMS finance?
For hire purchase, most lenders ask for 10–20% deposit. Finance leases and operating leases typically require no deposit. Given that BMS projects often combine hardware, software licensing and commissioning, lenders will usually want an itemised quote covering all three elements before confirming terms. Newer businesses or those with a thinner credit file may be asked for a deposit toward the higher end of that range, while an established business with several years of accounts can sometimes negotiate it lower, so it's worth discussing your specific position with a broker before assuming a fixed figure.
How quickly can I get BMS finance approved?
Straightforward single-building installations are often approved within 24 to 48 hours once accounts and a supplier quote are provided. Larger multi-site rollouts typically take longer, as underwriters usually want the phased implementation plan and total project cost confirmed before releasing funds across multiple sites. Having your accounts, bank statements and a signed supplier quote ready before you apply generally shortens the process, as underwriters otherwise have to pause and request the same documents before they can issue a decision.
