Surveyor & Architect Accountants
Accountancy Made Simple from only £89/month
Fees earned across project stages that span years, professional indemnity cover you have to carry long after the work is finished, and a Construction Industry Scheme that mostly doesn’t apply to you until suddenly it does. Caroola gives surveyors and architects a dedicated accountant who understands how a practice actually earns, on a fixed monthly fee.
Your fee is agreed at the start of a project and earned across the whole of it, which means what you’ve invoiced and what you’ve made are rarely the same number.


Specialist Accounting Support for Surveyors and Architects
Our accounting for surveyors and architects is provided by accountants who understand staged fees, long projects and professional practice, not a generic small business template.
You’ll get your own dedicated accountant, not a shared inbox or a rotating support team.
Support is unlimited, and quarterly check-ins mean your accountant is looking at your numbers throughout the year, not once, twelve months after the fact.

- Self Assessment, Partnership, or Corporation Tax

Who are these services for?
At Caroola, we work with practices of every structure, sole practitioners, partnerships, LLPs and limited companies, whatever you specialise in.
That covers architects and architectural technologists, building and quantity surveyors, chartered and party wall surveyors, structural and civil engineers, and building control and project consultants. Whether you practise alone or run a studio with staff, we can help.


What Makes Accounting for Surveyors and Architects Different?
A shop knows what it made last month. A practice working across RIBA stages on a scheme that started two years ago has a fee agreed at the outset, work delivered unevenly across the timeline, and invoices raised at milestones that rarely line up with either. Your profit depends on how that work in progress is measured, not on what you happened to bill.
The scheme that governs the industry you work in mostly leaves you alone, which is precisely why it catches people out.
Work in progress:
Fee income is recognised as the work is performed rather than when you invoice, so unbilled work on live projects belongs in your accounts.
CIS and professional work:
Work carried out within your normal professional discipline sits outside the Construction Industry Scheme, even where it involves supervision.
Where CIS does bite:
Acting as developer or principal contractor pulls you in, and a single contract that mixes professional work with construction operations brings the whole contract into the scheme.
Engaging subcontractors:
If your practice pays others for construction operations, you may become a contractor under CIS yourself and have to verify and deduct.
Professional indemnity:
Cover is a condition of practice, and run-off cover continues to cost money after you stop, which needs planning for rather than discovering.

FAQs
- Does the Construction Industry Scheme Apply to Me?
Usually not. Professional work carried out by architects and surveyors within their normal discipline is excluded from CIS, and that holds even where the role includes supervisory or executive responsibility. Two things change the answer. If you act as a developer or take on the construction work itself, you’re inside the scheme. And where one contract covers both professional services and construction operations, the whole contract is caught, not just the construction part.
- Do I Have to Deduct CIS From People I Pay?
Possibly, and it’s the side practices forget. The exclusion covers work you do, not work you buy in. If your practice engages subcontractors to carry out construction operations, you can become a contractor under the scheme, which means registering, verifying them with HMRC and deducting before you pay. Design-and-build arrangements are where this most often arises.
- When Do I Recognise Fee Income on a Long Project?
As the work is performed, not when you raise the invoice. On a scheme running across multiple stages, that means work you’ve delivered but not yet billed still belongs in the period you did it. Getting this right matters for your tax bill and matters more if you’re ever showing accounts to a lender or a prospective partner.
- Can I Claim My Professional Indemnity Insurance and Subscriptions?
In most cases, yes. Professional indemnity premiums, registration with your regulator and relevant professional body subscriptions are usually allowable where they’re required for your practice. Run-off cover is worth raising with us specifically, because the treatment of costs incurred after a practice has ceased follows different rules to costs incurred while trading.
- Should My Practice Be a Limited Company or an LLP?
It depends on how many of you there are, how you want to share profits and what you’re planning long term. LLPs suit practices with several principals who want flexibility over profit allocation while keeping limited liability. A company can be more tax efficient where profits are being retained rather than drawn. We’ll model both rather than give you a default answer.
- Can I Switch to Caroola Part-Way Through the Year?
Yes. No need to wait for year end. We manage the handover with your current provider.
