Clearer, Not Cleverer: The Case for Plain English in UK Commercial Advice

Commercial advice in the UK has a language problem. Too often, the more important the point, the more impenetrable the explanation. A liability cap becomes an aggregate limitation of liability subject to carve-outs. A price increase becomes an index-linked adjustment mechanism. A delay becomes programme slippage arising from resourcing constraints. None of these phrases is technically wrong. But if the client cannot see the commercial consequence, the advice has not done its job.

This is an opinion, so let us state it plainly: in 2026, commercial expertise needs a plain-English upgrade. SEH Ltd's tagline, commercial expertise delivered with clarity, is not a decorative promise. It is a working standard. Clarity is not the opposite of expertise. It is how expertise becomes useful.

Jargon can hide a decision

Jargon is not always deliberate obfuscation. It often comes from habit, from professional training or from a reasonable wish to be precise. The problem is that precision for the adviser can become opacity for the client. A contract clause may be legally accurate and still fail commercially because the person approving it does not understand what they are approving.

The consequence is not merely irritation. Clients disengage. Decisions are deferred. Risks are signed without proper scrutiny, and disputes emerge later when one party says it never understood the cost of exit or the limit on liability. In a difficult UK market, where budgets are scrutinised and suppliers are expected to justify every increase, opaque advice is a commercial liability in its own right.

What plain English actually looks like

Plain English does not mean dumbing down. It means putting the commercial consequence first and the technical detail second. Consider three common situations.

First, indexation. Instead of saying the contract contains an index-linked adjustment mechanism, say: the fee rises once a year by CPI, capped at 4 per cent, and the first increase applies next April. That sentence gives the client the timing, the measure, the ceiling and the date. It is shorter, clearer and more useful.

Second, project updates. Instead of programme slippage arising from resourcing constraints, say: we are two weeks behind because the electrical components arrived late. We have added a Saturday shift and the completion date moves from 12 June to 26 June. There is no change to the contract price. The client can now decide whether the new date is acceptable and whether any further mitigation is needed.

Third, risk. Instead of an aggregate liability cap with limited carve-outs, say: if this service fails, the most you can recover is £150,000 in total. That may not cover a serious outage. You can ask for a higher cap, but the supplier is likely to price that risk into the contract. The client can see the trade-off and make a judgement.

Three tests for clearer commercial advice

A useful test for any commercial explanation is whether the client can repeat the decision back in their own words. If they cannot, the explanation is not yet finished. A second test is whether the advice separates fact from judgement. It is one thing to say that a clause is market standard; it is another to say that it is market standard but poorly suited to a business-critical service. A third test is whether the advice states the cost of the alternative. Clear advice does not simply recommend a course of action; it shows what the client gives up by choosing it.

These tests are particularly relevant in 2026. Commercial teams are under pressure to move quickly, but speed without understanding creates rework. A renewal approved without clarity may have to be reopened. A project change accepted without a clear price may become a dispute. A risk accepted without a plain explanation may become a board-level surprise. Clear language is therefore not a soft skill. It is a form of commercial control.

Clarity builds trust

Trust in commercial relationships is built through repeated evidence that the other side will tell you the difficult thing plainly. Clients do not expect every contract to be risk-free or every project to run perfectly. They expect to be told what is happening, what it means and what choices they have. When that happens, the relationship becomes more resilient. Problems are raised earlier. Negotiations are shorter. Decisions are made by the people who understand them.

SEH Ltd's project updates and client conversations are designed around that principle. The aim is not to make complex matters sound simple when they are not. The aim is to make them understandable enough to act on. That is a more demanding standard than jargon, because it requires the adviser to know which detail matters and which detail is merely noise.

In 2026, commercial expertise should be judged not only by what it knows but by how clearly it can explain the consequences. The best partners will not hide behind technical language. They will set out the trade-offs, the risks and the costs in plain English, and they will let the client make an informed decision. That is not a lowering of standards. It is the standard.
