Why Capital Allowances Matter for Your Property-Holding Clients
Capital allowances matter because the numbers are rarely trivial. On unclaimed commercial property, embedded fixtures such as electrical systems, heating, ventilation, sanitaryware and integral features frequently represent 15% to 40% of the purchase price, depending on the property type. A £1 million commercial property acquisition can easily carry £150,000 to £300,000 of qualifying expenditure that has never been identified, let alone claimed, and the reason is usually simple: those items were never invoiced to the client as a separate purchase. They arrived already built into the property, which means there is no invoice trail for a general practice team to work from in the first place.
For your client, this translates directly into cash flow and yield. A successful claim reduces taxable profits, which reduces tax paid, which improves the return on the asset. For a client who has just completed on a hotel, care home, office building or industrial unit, this is not an abstract tax planning point, it is money that changes the economics of the deal they have just done. Clients who read about this in the property press, or hear about it from another advisor, will ask why it was not raised sooner if it was not raised at all.
The Specialist Knowledge Gap (and Why It's a Feature, not a Failure)
Most capital allowance claims prepared in general practice are built from what is in front of the accountant: invoices for plant, equipment and fit-out works that the client has paid for directly. That is sensible practice, and it captures real value. But it is also, by definition, incomplete. The largest pool of qualifying expenditure in a commercial property, the electrical wiring, heating and ventilation systems, lifts, sanitaryware and other integral features already built into the fabric of the building at the point of purchase, was never invoiced to your client as a separate line item. It was bought as part of the property, at a single price, with no paper trail attached to any individual fixture.
This is the gap that a specialist survey exists to close. A qualified surveyor apportions the purchase price across the building, identifies the plant and equipment fixtures and fittings (PEFFs) embedded within it, and values them against the case law that determines what does and does not qualify under the Capital Allowances Act 2001, none of which is taught in any depth at ACA or ATT level. Without that survey, an invoice-based claim will always understate what the client is entitled to, sometimes significantly.
This matters for reasons beyond the missed saving. If a claim goes through the accounts on the strength of invoices alone, and it later emerges, through a subsequent advisor, a sale, or the client’s own research, that a survey would have uncovered a materially larger claim, the question the client is entitled to ask is why that opportunity was not identified or flagged at the time. This is a potential negligence exposure for the firm that prepared it. Recommending a specialist survey is not extra caution; it is what protects both the client’s entitlement and your own position as their advisor.
This is precisely why sensible generalist firms do not try to carry this risk in-house. It is not a gap in your service. It is a deliberate and correct decision to let a claim of this technical depth sit with people who do just this, all day, every day.
Three Ways to Deliver Capital Allowances to Clients
Capital Allowance Review Service offers three models of capital allowance services for accountants, and the right one depends on your client base, your appetite for involvement, and how much of the fee you want to retain.
Refer the client directly (introducer model). We support you to identify the opportunity, you make the introduction to our specialist team, and step back while we deal directly with the client. This is the lowest-effort, lowest-risk route.
White-label service delivered through your firm’s brand. The specialist does all the technical work, scoping, surveying, valuation, and HMRC liaison, but the engagement is presented to the client as your firm’s service, delivered with specialist support behind the scenes.
In-house with specialist support on demand. For firms with a genuinely large property-holding client base, some choose to build limited internal capability, enough to identify and scope opportunities, while still outsourcing the survey, valuation and technical claim preparation to a specialist capital allowance advisor. This suits tax managers who want to own more of the process without taking on the surveying and case law risk.
None of these requires you to become a specialist. Each simply asks how much of the coordination you want to keep and how visible you want to be to the client. You are either paid a referral or introducer fee, or your client receives a reduced fee because of our relationship.
How a White-Label or Partnership Model Actually Works
We start with a clear engagement letter. It sets out who does what, so there’s no ambiguity for the client or for either firm.
The division of labour is straightforward. You spot the opportunity and introduce your specialist partner. The partner scopes the claim, arranges the property survey, prepares the valuation, and handles any Section 198 election support or HMRC liaison. You stay the client’s main point of contact throughout, and receive full reporting on progress.
Fees are usually no-win, no-fee for the client, with the specialist paid often from the tax saving achieved.
We agree a separate referral or revenue-share arrangement between our firms. That means no upfront cost risk for your client, and a clear, transparent commercial arrangement between you and us.

Doing It In-House vs Partnering with a Specialist
How to Spot a Capital Allowance Opportunity in Your Existing Client Base
You do not need technical knowledge of capital allowances for accountants to spot an opportunity; you just need to know which questions to ask at the right moment. A short conversation can usually tell you whether a review is worth pursuing:
Has the client bought, built, extended or refurbished a commercial property in the last few years? Has a claim ever been made on that property before, by any previous owner or advisor, and if so, was it built from invoices alone, or backed by a specialist survey? Is the client planning to sell, or has a sale recently completed, where Section 198 election support will be needed to preserve allowances for both parties? Has the property moved within a group structure, or between connected parties? Is the client aware that unclaimed allowances from previous years can often still be recovered?
The moments that most reliably trigger an opportunity are acquisition, refurbishment, build, sale and intra-group transfer. If any of these events appear in a client’s recent history and no capital allowance review has taken place, it is worth a conversation with us, not necessarily with the client yet.
Working With Solicitors on Property Transactions
Capital allowances are frequently missed, or mishandled, at the point of a property transaction, and this is usually a solicitor issue rather than an accountant issue. The Commercial Property Standard Enquiries form, specifically CPSE.1 Section 32, is where capital allowances should be addressed between buyer and seller. In practice, this section is often completed without proper input from a specialist, meaning the buyer’s solicitor may not prompt for the tax election that protects future allowances, or may accept wording that inadvertently blocks the buyer’s ability to claim at all.
A three-way collaboration between accountant, solicitor and Capital Allowance Review Service at the point of transaction protects the client from this gap. We can review the wording, advise on the Section 198 election, and ensure the right values are agreed and documented before completion, after which point it is often too late to correct. Raising this early, as part of your client’s transaction support, is a visible example of the value an accountant adds well beyond compliance work.
What Good Specialist Partner Support Looks Like
Not all capital allowance advisors are equal, and it is worth being direct about what to expect from a
good one. This is exactly what we built the Capital Allowance Review Service (CARS) around.
Team. Our claims are built by a team of Chartered Tax Advisers, RICS-qualified surveyors and
specialists with direct HMRC inspection experience, the combination that gives a claim its
credibility if it is ever questioned.
Fees. We work on no-win, no-fee terms directly with the end client, so there is no cost risk for your
client to weigh up.
Reporting. We keep you updated at every stage, not just with a fee note at the end.
Support. We invest in your team with ongoing technical support, CPD sessions and training, so your
staff get better at spotting opportunities over time, without ever needing to run a claim
themselves.
That is what to look for in any specialist partner, and it is what a conversation with CARS gives you
from the outset.

Concerns We Hear from Accountants
Will I lose my client?
This is the concern behind almost every hesitation, and it deserves a direct answer: look at the track record, not just the promise. We’ve built relationships with accountancy firms over many years, and the same firms keep referring to us project after project. That only happens because the accountant stays in control of the relationship and we support it rather than compete with it. The testimonials we can show you from firms we’ve worked with for years are better evidence of this than any assurance we could write here.
Read about how an Accountant feels about our support.
How do I explain the fees to my client?
There are no upfront costs and we are typically paid a percentage of the capital allowance identified, on a no win, no fee basis, so the client only pays if the process is successful. There is no cost risk to raise with them, which makes this one of the easier fee conversations you will have.
What happens if HMRC enquires?
We stand behind our claims with full evidence and will handle HMRC correspondence directly, keeping you informed throughout. This is one of the clearest reasons not to attempt a DIY claim; the liability sits with people who prepare and defend these claims routinely.
Haven't we already claimed everything through the client's invoices?
Probably not. Invoices only capture what was purchased separately; they say nothing about the fixtures already built into the property when your client bought it. Those embedded items are usually the largest part of the claim, and they can only be identified and valued through a specialist survey. Leaving them unreviewed means the client’s claim was never maximised, which is a conversation worth having before someone else has it with them.
FAQs
How do accountants handle capital allowances for clients?
Most general practice accountants identify potential opportunities during routine client work, at acquisition, refurbishment or sale, and refer the technical scoping, surveying and claim preparation to a specialist capital allowance advisor, while retaining the primary client relationship.
Should accountants outsource capital allowance claims?
Yes, for the vast majority of firms. The specialist knowledge, surveying discipline and case law expertise required sits outside general practice, and a properly structured partnership lets you deliver the value to clients without carrying the technical or liability risk.
What is a white-label capital allowance service?
A white-label arrangement is where a specialist performs all technical work, scoping, surveying, valuation and HMRC liaison, behind the scenes, while the engagement is presented to the client under your firm’s brand, with you retaining the client relationship throughout.
How do accountants get paid when referring capital allowance work?
Arrangements typically involve a referral fee or revenue share agreed between your firm and us, funded from the fee we charge the client, which is usually structured on a no-win, no-fee basis.
Will my client be poached if I refer them?
Look at what has actually happened over years of accountant partnerships with CARS, not just what we say we’ll do. Firms keep referring to us project after project, year after year, which is the clearest evidence that the relationship works without the accountant losing control of their client. That is the story our testimonials tell: long-standing relationships built on support, not one-off wins.
Read our testimonials.
How do I know if my client has a capital allowance opportunity?
Ask whether they have acquired, refurbished, built, or sold a qualifying commercial property, and whether any previous owner or advisor has already claimed. Property types such as hotels, care homes, and offices almost always justify a closer look.
What CPD or guidance does CARS provide to the accountant team?
A good specialist partner offers ongoing training sessions, CPD-eligible briefings and informal coffee mornings to help your team recognise opportunities in client conversations, without expecting anyone in your firm to become a technical expert.
