- How an established practice added £34,000 of headroom to an existing facility
- Why milestone-based fee income creates working capital gaps for design practices
- What a top-up advance is and when it makes more sense than refinancing
An architectural practice in South West England, trading for more than 15 years, secured a £34,000 unsecured business loan through Spark Finance to support working capital while fee income on live projects remained outstanding. The practice already held a facility and needed additional headroom rather than a replacement.
Fee income in design-led professional work arrives against project milestones, which means the practice carries its salary bill through the gaps between them.

Background
Architectural practices earn fees in stages, typically tied to the completion of a design phase or the submission of an application, rather than as a monthly retainer. A practice can be busy across a full portfolio of projects and still be waiting on the cash from most of them.
This practice had been established for more than 15 years and had a mix of work in progress across several projects at different stages. Salaries and professional overheads are the dominant cost in the sector and they do not flex with the billing cycle.
The practice had taken funding previously to smooth those gaps and was part way through repaying it when a further requirement arose, which raised the question of whether to replace the existing facility or add to it.
The Challenge
Adding to an existing facility is a different underwriting question from taking a first one, because the lender is assessing whether the business can carry both. The practice needed a further £34,000 while an earlier facility was still running, and its filed accounts did not yet reflect the current order book.
- Accounts not current at Companies House at the point of application
- A constrained balance sheet with outstanding liabilities, including the facility already in place
- Fee income tied to project milestones rather than to a predictable monthly cycle
- A requirement for additional headroom without disturbing the existing arrangement
Our Approach
Spark Finance pursued a top-up advance rather than a refinance, keeping the existing facility in place and arranging the additional £34,000 alongside it. That route avoids settling an arrangement part way through and re-establishing terms from scratch, which for a practice carrying work in progress is usually the more expensive outcome.
Because the request sat outside an automated decision, the case went to a manual review, which meant the order book and the timing of expected fee income could be put in front of an underwriter rather than reduced to a score.
- Structured the request as a top-up advance rather than a refinance
- Took the case to manual underwriting so the order book could be assessed directly
- Set out how milestone fee income would service both facilities together
- Presented the current trading position where filed accounts were not up to date
Outcome
This allowed the practice to:
- Meet salary and overhead costs while project fees remained outstanding
- Keep its existing facility and its terms undisturbed
- Continue progressing live projects without pausing work for cashflow reasons
The client pointed to the structure of the top-up and to the speed of the response as the reasons for proceeding with Spark Finance. This case demonstrates that established architectural practices with milestone-based fee income can access unsecured business finance through a specialist FCA-authorised broker, even where a facility is already in place and accounts are not current.
What is an Unsecured Business Loan?
An unsecured business loan is commercial finance provided without a specific asset pledged as security, assessed instead on trading performance and affordability. Where a business already holds one, some lenders will consider a top-up advance that runs alongside the original rather than replacing it.
- No asset is pledged as security
- Terms commonly run from 12 months to 5 years
- A top-up can sometimes be arranged on an existing facility
- Affordability is assessed across all existing commitments, not just the new one
- A personal guarantee from a director may be required
Unsecured funding suits professional practices whose costs are almost entirely people and premises, where there is no meaningful asset to offer as security in the first place.

Frequently Asked Questions
Can a business top up an existing unsecured loan?
Some lenders will consider an additional advance alongside a facility already in place, subject to affordability across both. In this case Spark Finance arranged a further £34,000 for an architectural practice without settling the original facility.
How much can an architectural practice borrow on an unsecured basis?
Amounts are usually set against fee income and affordability rather than against assets, which matters in a sector with little to pledge. Facilities in the tens of thousands are common for practices of this size, and the panel of 100+ UK lenders can consider a range of amounts.
How long does an unsecured business loan take to arrange?
Straightforward cases assessed automatically can complete within a few days. Where a case goes to manual underwriting, as this one did, it usually takes longer but allows the order book and the timing of income to be considered properly.
Does an existing loan reduce the chance of getting another one?
Not on its own. Lenders assess whether income supports the total repayment across all commitments, so an existing facility being serviced on time can help rather than hinder. Accounts that are not current at Companies House can usually be addressed with recent management information and bank statements.
The bottom line
A £34,000 top-up kept this practice trading through the gap between design stages without disturbing an arrangement that was already working. With more than 100 UK lenders on the panel, additional headroom is a question worth asking before assuming a full refinance is the only route.
