What Does a Bid Writing Success Rate Really Tell You in 2026?

A bid writing success rate tells you how often the bids a company supported ended in something it counted as a win. It does not tell you how difficult those bids were, how many suppliers competed, or whether a win meant guaranteed work.

Care Sync Experts analysed 971 health and social care contract lots awarded in England under the Procurement Act 2023 during 2026. The results show why two bid writing companies can report very different success rates even when their performance is similar.

This guide explains how success rates are calculated, what the 2026 public record shows, and which questions care providers should ask before choosing a bid writer.

Key Takeaways

• There is no standard method for calculating a bid writing success rate.
• Around 27% of final-stage tenders won single-supplier social care lots in our 2026 dataset.
• Around 78% of final-stage tenderers were appointed on multi-supplier social care lots.
• A framework place is not guaranteed work or revenue.
• Ask for sample size, tender type, timeframe and the firm’s definition of a win.
• Assessment scores and work received often reveal more than a headline percentage.

What a Bid Writing Success Rate Actually Measures

A bid writing success rate is usually calculated as bids won divided by bids submitted. The problem is that each firm can choose what it includes on both sides of that calculation.

A company may count every lot as a separate win, exclude rescue bids, include framework places, or report only a strong period. None of those choices automatically makes the figure false. They do make comparisons unreliable unless the method is explained.

Choice the firm makes	Option that raises the rate	Fairer reporting approach
What counts as a bid	Only full bids the firm selected	Every submission the firm worked on, including reviews and rescues
What counts as a win	Framework places, shortlists or selection-stage passes	Signed contracts, with framework places reported separately
How lots are counted	One 12-lot tender becomes 12 wins	Report the procurement once and show lot results separately
Which period is used	A particularly strong year	A rolling 12-month period with the number of bids stated
Which clients are included	Established incumbents only	Separate results for incumbents, new providers and unrated providers

Google UK results reviewed in October 2026 included published figures from 80% to 93%. The stronger examples gave some context about the calculation. Most still did not provide enough information for a care provider to compare like with like.

What 2026 Contract Data Shows About Winning Care Tenders

Care Sync Experts analysed public contract award notices available through the Find a Tender Open Contracting Data Standard service. The review covered notices published from 2 January to 13 October 2026 for health and social work services in England, where the notice included usable bid statistics and the procurement used an open or competitive flexible procedure.

After removing lots with missing or impossible figures, the dataset contained 971 lots from 610 notices and 254 buyers. Social care services, using Common Procurement Vocabulary codes beginning 853, accounted for 390 lots.

Measure	All health and social care lots	Social care lots only
Lots analysed	971	390
Median tenders received per lot	5	5
Median tenders at the final stage	4	3
Lots awarded to one supplier	73%	76%
Single-supplier lots with one final-stage tender	28%	28%
Final-stage tenders winning single-supplier lots	26.6%	27.1%
Same measure where at least 2 tenders reached the final stage	20.7%	21.0%
Final-stage tenderers appointed on multi-supplier lots	76.7%	77.9%
Multi-supplier lots appointing every final-stage tenderer	44%	45%

The award structure changes the odds

Single-supplier and multi-supplier opportunities should not sit in the same performance bucket. In the social care data, an average final-stage tender had roughly a 27% chance of winning a single-supplier lot. On multi-supplier lots, around 78% of final-stage tenderers gained a place.

This means a firm that mainly writes framework and approved provider list applications can report a much higher headline rate than one focused on single-supplier block contracts. The difference can arise before writing quality is considered.

Some final stages had only one tenderer

More than one quarter of single-supplier lots in the dataset had only one tender left at the final stage. A bid that reached that point won by definition.

That may still represent good bid selection, compliance and delivery. It is not the same competitive achievement as beating several compliant final-stage tenders.

Competition varied sharply between procurements

The public record shows why a single industry average is difficult to defend.

Procurement example	What the published record or Care Sync dataset showed
Essex County Council, Live at Home 2025	A 12-lot, 2-tier framework with no limit on Tier 2 places
North Northamptonshire supported living	194 tenders received, with every final-stage tenderer appointed in 5 lots with complete figures
Leicestershire Homecare 2026	Lot 1 recorded 544 tenders received, 136 final-stage tenders and 95 appointed suppliers
Reading Borough Council supported living framework	Final-stage tenderers and places varied substantially across the 3 lots
Milton Keynes supported living	118 bids, 71 passing the first stage and 10 places in each of 4 lots
West Sussex community reablement	15 tenders, 5 passing due diligence and 1 recommended supplier
Ealing extra care	11 tenders in a mini-competition and 1 provider awarded both contracts

A bid writer could support several successful appointments to a broad framework and report a perfect result. Another could support the sole winner of a highly contested reablement contract. Both are wins, but the second result may demonstrate more about competitive bid quality.

Limits of the data

This analysis is a base rate, not a prediction for your next bid. It covers above-threshold notices with usable bid statistics. Multi-stage procedures can describe early responses and final tenders differently, whilst some multi-lot notices repeat a notice-wide figure across lots.

The figures also average strong and weak bidders together. Your experience, price, evidence, location and compliance position can move your real prospects well above or below the average.

Why a 90% Success Rate Can Mean Less Than a 50% One

The mix of opportunities can change the meaning of a success rate. Consider 2 fictional firms using the 2026 social care base rates.

Measure	Firm A	Firm B
Published success rate	85%	50%
Bids for frameworks and lists	80%	10%
Bids for single-winner contracts	20%	90%
Expected rate for an average bidder with that mix	about 68%	about 32%
Gap above the mix-adjusted base rate	about 17 points	about 18 points

Firm A appears 35 percentage points stronger. Once the tender mix is considered, the 2 firms perform at a similar level above the relevant base rate.

This worked example is deliberately simple. It assumes each bid reached the final stage and that both client groups were typical. Its purpose is to show why the question, “What kind of bids make up your figure?”, matters more than the headline percentage.

Six Things a Bid Writing Success Rate Hides

A bid writing success rate can conceal factors that have little to do with writing quality.

1. Incumbency

An incumbent provider can bring contract data, service outcomes, workforce evidence and local knowledge that a new entrant does not yet have. A bid writer working mainly with established incumbents is likely to report stronger results.

2. Selectivity

A firm that declines poor-fit opportunities protects its rate. Good bid or no-bid advice is valuable, but the selection policy should be clear when the firm presents its performance.

3. Framework places counted as contracts

Many care frameworks appoint several suppliers. A place can be commercially useful, but it should not be presented as guaranteed revenue.

4. Client readiness

A writer cannot invent a Care Quality Commission rating, accounts, workforce capacity, contract history or local mobilisation plan. The client’s evidence base changes the probability of success.

5. The scope of the firm’s work

Proofreading a nearly complete submission is different from managing the process from bid or no-bid decision to final upload. Both may be described as tender support unless the firm separates them.

6. Price and non-quality criteria

Care tenders frequently score price, social value, mobilisation and compliance alongside quality. A strong written submission can still lose because another tender offered a better overall result against the published criteria.

What Winning Means in a Care Tender

Winning should describe the commercial outcome clearly. A single-supplier contract, a framework place, admission to a dynamic market and a selection-stage pass are different outcomes.

The Cabinet Office frameworks guidance says that, in most cases, a framework does not commit a contracting authority to award a call-off contract. Its dynamic markets guidance also confirms that admission to a dynamic market is not the award of a public contract.

For a care provider, the better follow-up question is: what happened after appointment? Useful evidence includes packages received, call-off value, hours delivered and the time between appointment and first work.

Are Bid Writing Success Rate Claims Regulated?

A bid writing success rate on a company’s website is an objective marketing claim. The Advertising Standards Authority’s substantiation guidance explains that marketers should hold documentary evidence for objective claims before publishing them.

Two April 2026 rulings show why the calculation must be clear. The ASA challenged a 92% pass-rate claim where the basis was not clear, and a separate 72% figure that combined first and second attempts. Neither ruling concerned bid writing, but the same advertising principle is relevant: readers should understand what the percentage measures.

A bid writing company should therefore be able to explain its denominator, the period covered, exclusions, tender types and definition of success. A care provider should not have to infer these details from a single large number.

Better Measures Than a Bid Writing Success Rate

A bid writing success rate is more useful when it is combined with outcome, quality and commercial evidence.

Compare your scores with the winning scores

The Cabinet Office assessment summaries guidance explains the feedback suppliers should receive after an assessed tender under the Procurement Act 2023. Comparing your score by criterion with the winning tender shows where quality improved and where the gap remains.

Assessment summaries are not required in every circumstance, including some framework call-offs and dynamic market admissions. Where you receive one, use it as a learning document rather than filing it away.

Track the quality score trend

A rise from 2 to 3, or from 3 to 4, on repeated quality themes can show that the process is improving even before the organisation starts winning consistently.

Separate results by opportunity type

Report single-supplier contracts, frameworks, dynamic markets, approved lists and selection-stage outcomes separately. This removes the largest distortion in the headline percentage.

Measure work received

For every framework or provider-list appointment, record packages, call-offs, hours and income received after 6 and 12 months.

Explain losses

A credible bid partner should be able to review an unsuccessful submission, identify the score gap, and distinguish between writing, evidence, pricing, compliance and tender-selection problems.

Questions to Ask a Bid Writer Before You Hire Them

Ask how the bid writing success rate is calculated, then use these questions in your first conversation with any bid writing company.

Question	A useful answer	Warning sign
How many bids is your rate based on?	A stated sample size and recent period	No number or an all-time claim
What counts as a win?	Contracts and framework places shown separately	Shortlists and passes included without explanation
What share of your work is multi-supplier?	A clear split by opportunity type	“We do not track that”
Can I see anonymised losses?	Examples showing scores and lessons	Only positive testimonials
Do you specialise in care?	Care-specific evidence and commissioning examples	Generic answers that could fit any sector
Who will write and review my bid?	Named roles and a second quality review	Unclear delivery team
Will you advise us not to bid?	Yes, with evidence-based reasons	Every opportunity is treated as a good fit
Can you guarantee a win?	No	A guarantee or unclear money-back promise
How do you use artificial intelligence?	Clear disclosure, human checks and data controls	Vague answers or no verification process

Government PPN 017 on artificial intelligence in procurement does not prohibit suppliers from using AI in bid writing. It encourages proportionate transparency and verification. Buyers may use clarification questions, presentations or site visits to test the accuracy and credibility of a tender.

Every statement in your submission must therefore be true of your organisation and supported by evidence.

What New Care Providers Should Look For

For a new care provider, a bid writing success rate based on established operators alone is a weak benchmark. The relevant question is whether the firm understands how to position a provider with limited contract history without inventing evidence.

Some care opportunities accept unrated or newly registered providers. Others set minimum regulatory, financial or experience conditions. Read the conditions of participation before committing time and money, and ask a clarification question if the requirement is unclear.

Choosing the right opportunity matters as much as the writing. This Care Sync Experts video shows how tender selection can prevent wasted work and improve focus.

Strong support for a new provider should include:

1. A realistic bid or no-bid review.
2. A gap check against mandatory conditions.
3. An evidence plan using real staff, policies, systems and mobilisation commitments.
4. A pricing and cash-flow check.
5. A clear explanation of what cannot yet be evidenced.

Our guide to the most common bid writing mistakes explains how weak evidence, poor tender management and missed instructions can damage an otherwise capable submission.

How Care Sync Experts Reports Tender Results

Care Sync Experts does not rely on one headline win rate. We report the opportunity, the support provided, the result and, where possible, the published evidence behind it.

Our tender process starts with fit. We compare the opportunity with your registration, service model, location, finances, workforce and experience before recommending whether to proceed. If the opportunity is suitable, we plan each answer against the scoring criteria and build the submission around evidence your organisation can prove.

You can review our healthcare tender writing service and published success stories before speaking with the team.

Final Thoughts

A bid writing success rate is a starting point for a conversation, not a reason to hire a firm. The 2026 health and social care data shows that tender structure can change the apparent odds from roughly one win in four to more than three appointments in four.

Ask what counts as a win, how many bids sit behind the figure, which opportunity types are included and whether clients received real work. Then look at evidence that is harder to dress up: assessment scores, quality trends, loss reviews and call-off outcomes.

FAQ

What is a good bid win rate?

A good bid win rate depends on the type of opportunity. Care Sync Experts’ 2026 dataset found that around 27% of final-stage tenders won single-supplier social care lots, whilst around 78% of final-stage tenderers gained a place on multi-supplier lots. A provider winning one in three contested single-supplier bids may therefore be performing strongly, whilst a 70% rate built mainly on broad frameworks may be less impressive. Compare the result with a relevant base rate.

Is a 90% bid writing success rate realistic?

A 90% bid writing success rate can be realistic when the figure includes frameworks, approved provider lists or carefully selected opportunities. It would be exceptional for a sustained record of contested single-supplier contracts. Ask for the sample size, period, opportunity mix, exclusions and definition of a win. The company should also explain whether each lot is counted separately and whether a framework place led to actual work.

How do bid writing companies calculate their success rate?

Most companies divide wins by submissions, but there is no standard calculation. Firms may differ on whether they include reviews, rescue bids, shortlists, framework places, individual lots or pending results. Some report an all-time figure, whilst others use a recent 12-month period. A useful figure should state the number of bids, the timeframe, the types of opportunities and the precise outcome counted as success.

Does a framework place guarantee work?

No. A framework place usually makes a provider eligible for future call-offs, mini-competitions or brokerage, but it does not normally guarantee a contract, care package or revenue. Cabinet Office guidance says that, in most cases, a framework does not commit the contracting authority to enter into a call-off contract. Care providers should track the work received after appointment and plan staffing and cash flow around confirmed packages rather than the framework place alone.
