Most founders do proper diligence on the numbers. Rent per square foot, service charge, business rates, break clause, the cost of getting the space to look like the brand.
What almost nobody does before signing a lease on an older unit, workshop or first-floor office is ask what the building is made of. It is a boring question with an expensive answer, because for premises built before 2000 the wrong answer stops the fit-out, moves the opening date and puts a legal duty on your company rather than your landlord’s.
Firms handling asbestos removal in Hampshire and across the UK see the same pattern constantly: a new tenant three weeks into a fit-out, contractors standing down, and an opening date that has quietly become a guess.
This is not a health and safety article. It is a cost control and scheduling one.

The Clause That Transfers The Risk To You
Asbestos was not fully banned in the UK until 1999, and around 1.5 million UK buildings are still thought to contain it. Regulation 4 of the Control of Asbestos Regulations 2012 places a duty to manage asbestos on non-domestic premises. The important detail is who carries that duty.
It sits with the dutyholder, defined as the person or organisation responsible for maintenance or repair of the premises by virtue of a contract or tenancy.
Read that again with your heads of terms open. Sign a full repairing and insuring lease, and you have taken on responsibility for maintaining the building fabric. In a lot of cases that makes your business the dutyholder, not the landlord, from the day the lease completes.
In multi-let buildings it gets messier. Leases often split responsibility between landlord and tenants without ever stating who owns the building fabric. That is how the duty ends up in a gap that nobody is actively holding, which is fine right up until someone drills into a ceiling void.
The duty itself is not onerous. Find out what is there, record it in a register, assess the risk, write a management plan and act on it. What is expensive is discovering on day one of trading that the duty was yours all along and nothing had been done.
What The Landlord Gives You Is Rarely What You Need
Ask for the asbestos register and management plan during diligence, not after. When it arrives, three checks matter more than the fact it exists.
Check what type of survey it is.
A management survey covers material that is visible and accessible during normal occupation. It is the right document for using a building as it stands. It is not a document that tells you what is behind the stud wall you are about to remove.
Check the date and the scope.
A survey from 2011 that predates two previous tenants’ fit-outs describes a building that no longer exists. Registers are meant to be live documents, reviewed and updated.
Check whether it covers your works.
Any structural alteration, service run, ceiling grid removal or new partition needs a refurbishment and demolition survey. That one is intrusive by design, because it opens up the areas your build will disturb and samples them.
Surveyors carrying out this work are qualified to BOHS P402 standard or higher, and samples are analysed at a UKAS-accredited laboratory.
Commission that survey before you sign, or make it a condition of the lease. A finding before exchange is a negotiating position on rent, rent-free period or a landlord contribution.
The same finding after completion is your problem and your invoice.
The Maths Of A Delayed Opening
This is the part that turns a compliance topic into a business one.
Your rent-free fit-out period is finite. Say you have negotiated eight weeks. Your contractor opens up a ceiling in week two and finds insulation board. Work stops on that area immediately.
A survey and sampling turnaround takes a few days. If the material falls into the licensed category, the removal contractor has to give the HSE fourteen days’ notice on form ASB5 before work can start. Then there is the removal itself inside a sealed enclosure, followed by a four-stage clearance air test before anyone is allowed back into the space.
Four to five weeks have gone from an eight-week window, and none of your trades were working during it. The knock-on costs are the ones that actually hurt.
Staff hired to a start date. Stock arriving to a warehouse you cannot use. A launch campaign booked against an opening weekend. Rent starting on a unit that is not trading. Very few first-time tenants have a contingency line big enough to absorb that, because it was never in the model.
Enforcement Has Got Busier, Not Quieter

The HSE launched its Asbestos: Your Duty campaign in January 2024 specifically to improve dutyholder understanding of Regulation 4, and it has continued stepping up inspections since, with inspectors visiting premises and construction sites to check how asbestos is being managed.
Prosecutions for management failures are a live enforcement route rather than a theoretical one. One recent case saw two companies fined a combined £88,300 and a site manager given a suspended prison sentence over failures to manage asbestos risks.
There is a commercial dimension too. Around 2,500 people die from mesothelioma in the UK each year, and the HSE estimates roughly 5,000 asbestos-related deaths annually across all conditions.
An exposure incident involving your staff or a contractor on your premises is an insurance conversation, an employment liability conversation, and a reputational one, all at the same time.
Your Pre-Signing Checklist
Five questions, all answerable before you commit.
When was the building constructed or last refurbished. Anything pre-2000 needs the rest of this list.
Does an asbestos register and management plan exist, what date is it, and what survey type produced it.
Under this lease, who is the dutyholder once we complete. Get your solicitor to answer this in writing rather than assuming.
Do our planned works require a refurbishment and demolition survey, and who is paying for it.
If something is found, who bears the removal cost, and does the rent-free period extend to cover the delay. This is a normal negotiating point and landlords are used to it.
The Bill At The Other End Of The Lease
One more thing worth pricing at the start. Dilapidations at lease end can require you to reinstate the premises, and works you carried out during your occupation can pull asbestos liability back to you years later.
Removal work generates a hazardous waste consignment note and a clearance certificate. Keep both, alongside the survey, in the same file as your lease. That folder is what settles an argument at the end of a ten-year term.
Where This Lands
The survey is a modest fixed cost, usually a fraction of a single month’s rent. Removal, where it is needed, is a defined job with a defined timeline. What is not defined, and what no founder can budget for, is finding out in the middle of a fit-out with a signed lease, a hired team and a launch date already in the market.
Ask the question during diligence. It is the cheapest week of the whole project.
