The cover letter on a bid is almost always treated as a formality. It is the page nobody really thinks about — written quickly, often at the end of the process, in language borrowed from the last cover letter. It says the team is pleased to submit, expresses confidence in the proposal, thanks the evaluator for the opportunity, and signs off. The content is unmemorable by design. The cover letter is treated as scaffolding rather than as a piece of writing in its own right.
This is a missed opportunity. The cover letter is the first thing the evaluator reads. It is the only piece of the bid that is positioned to set tone, frame the response, and direct the reader’s attention to what matters. A cover letter that uses its position deliberately does real persuasive work — sometimes more than any individual section in the main bid. A cover letter that treats itself as a formality squanders the position. Most cover letters squander the position.
What evaluators actually do with the cover letter
The cover letter is rarely scored. That is part of why bidders underinvest in it. If there are no marks attached, the writing logic goes, there is no reason to put effort into it.
That logic misses how evaluators actually read a bid. The cover letter is the first thing they encounter. It sets their expectations for the rest of the document. A confident, focused, specific cover letter inclines the evaluator to read the rest of the bid with goodwill. A generic, formulaic cover letter inclines them to read the rest of the bid more sceptically. Neither of these is conscious. Both are real.
The cover letter also tells the evaluator, in compressed form, what kind of bidder they are about to read. The bid that opens with “We are pleased to submit our proposal in response to your tender” sounds like every other bid. The bid that opens with a specific statement of what the bidder understands the procurement to be about, and why they are well placed to deliver it, sounds different. The difference is small in any individual sentence. It is meaningful across a full page.
One more thing the cover letter does: it is often the page the evaluator returns to when they are writing their internal recommendation. If the bid wins, somebody on the evaluation panel has to explain to the decision-makers why this bidder was chosen. The phrases they reach for in that explanation often come from the cover letter, because that is the part of the bid that summarised the bidder’s pitch. A cover letter that includes one or two specific, repeatable phrases gives the recommending evaluator something to hand on. A cover letter full of generic language gives them nothing.
What a working cover letter actually does
A cover letter that earns its place tends to do four things, briefly and confidently.
It shows that the bidder has understood the procurement. Not by saying “we have read the brief and understood it” — that says nothing — but by demonstrating the understanding in the opening sentences. A reference to the specific challenge the client is facing, in language that suggests insight rather than restatement. Something the bidder has noticed that other bidders may not.
It states the bid’s central proposition. The one or two sentences that summarise why this bidder is the right choice for this competition. Not “we are an experienced provider with a strong track record” — that could be said by anyone — but a specific claim about what this bidder uniquely offers for this brief. The win theme, in compressed form.
It directs the reader’s attention. A short pointer to the sections of the bid that the evaluator will particularly want to read. “Our methodology section addresses the specific data quality concerns raised in section 3 of the brief.” This is small, but it tells the evaluator the bid has been written for them, with their evaluation framework in mind.
It is signed by a real person, in a way that suggests human attention. Not just a generic team signature, but the name of someone who can be contacted, in a tone that suggests they have read the brief and the bid themselves.
That is the core. Four moves, in a page. None of them takes long to write once the bid itself is clear. Together they shift the cover letter from formality to function.
The phrases to avoid
Most cover letters fail by sounding like every other cover letter. The phrases that produce this effect are well-known once you start looking for them.
“We are pleased to submit our proposal in response to your tender for…” The opening sentence of approximately eighty per cent of bid cover letters. It says nothing the evaluator does not already know. It postpones the actual content. It signals that the rest of the cover letter is going to be similarly empty.
“With our extensive experience and proven track record…” Said by every bidder. Means nothing without specifics. A cover letter that includes this phrase has not yet done the work of saying what the experience actually is.
“We are confident that our proposed solution will deliver exceptional value…” Confidence is implied by the bid existing. Stating it adds no information. The space could have been used for the specific claim that backs the confidence.
“We look forward to the opportunity to discuss our proposal in further detail…” Closing line of approximately eighty per cent of bid cover letters. The procurement process either includes presentations or it does not. The line says nothing either way.
None of these phrases is wrong in any specific sense. They are just empty. A cover letter built out of them is a cover letter that has not used its position. The fix is to replace each generic phrase with a specific one — about this bid, this client, this competition.
A specific example, briefly
Compare the two openings.
The generic version: “We are pleased to submit our proposal in response to your tender for the provision of GIS consultancy services to the local authority. With our extensive experience in the public sector and our proven methodology, we are confident that we will deliver exceptional value across the term of the contract.”
The version that does work: “Your tender notes that the current GIS estate is fragmented across three departments, with no single owner of the underlying data model. We have led similar consolidations for two other UK local authorities in the last three years. The team we are proposing for this engagement includes the lead consultant from both of those projects, and our methodology is built specifically around the data ownership question that section 4.2 of your brief identifies as central.”
The second opening is not longer than the first by much. It contains specific references — to the brief, to comparable past work, to the named individuals involved. It demonstrates rather than asserts. It gives the evaluator something to remember, something to refer back to, and something to recount in their internal recommendation. It does the work.
Length and tone
A working cover letter is short. One page is the conventional maximum, and most cover letters benefit from being shorter than that. Half a page is often enough. The discipline of fitting the four core moves into half a page forces the writer to leave out everything that is not pulling its weight.
The tone is professional but not stiff. The letter is from a person, addressed to a person, and the writing can acknowledge that without becoming overly familiar. A small amount of warmth — the kind that suggests the bidder is a pleasant team to work with, not just a capable one — comes across in cover letters that read as written rather than templated.
The signature matters. A named individual, with their role, and a way to contact them. Not a generic team email. Not a scanned signature image with no name beneath it. The cover letter is the only place in the bid where the evaluator meets the bidder as people rather than as a company.
The short version
The bid cover letter is treated as a formality and written like one. The cost of that treatment is that the first page of the bid does no work, and the evaluator begins reading the rest of the proposal with neutral expectations rather than positive ones. A cover letter that uses its position deliberately — demonstrating understanding of the procurement, stating the central proposition, directing attention to key sections, signed by a real person — earns the goodwill that makes the rest of the bid easier to read. The writing is small. The effect is not.
