Comparison

UK bid writing companies, honestly compared

We write these comparisons ourselves, which you should factor in. So each one names the cases where the other firm is the better choice, and none of them restate a rival's marketing. Reviewed 22 August 2026.

The market consolidated in July 2026, and that changes the choice

On 29 July 2026, Thornton & Lowe and Executive Compass, two of the three most visible names in UK bid writing and direct competitors since both were founded in 2009, came together under the newly formed Procurement Growth Group. The group describes itself as the UK's largest specialist bid writing group with a 76-strong team. Dave Thornton became Group CEO, Neil Capstick Group Strategy Director and Christian Rowe Group Commercial Director, with Tom Sander-Daniel and Matthew Walker continuing as managing directors of the respective firms.

This is a straightforwardly good outcome for the businesses involved and we would not pretend otherwise. For buyers it narrows the field, and it raises one question that neither firm has an obvious incentive to answer: on a framework lot attracting dozens of bidders, what happens when two of them are advised from inside the same group?

That is not an accusation. Large professional services groups manage conflicts routinely and there are established ways to do it. But the client is entitled to ask how the information barriers work, who sees the pricing strategy, and whether the same evaluator-facing arguments are being developed on both sides of a competition. Ask for the answer in writing. Ask us the same question, and the answer is that Glaxtons is a single independent firm with no sister company in the market.

The comparisons

Procurement Growth Group vs Glaxtons

Formed 29 July 2026 · Bolton and Newcastle

Two of the three most visible names in UK bid writing became one company in July 2026. Clients of either firm are asking what changes: who writes their next bid, whether pricing moves, and whether the firm now also acts for the competitor sitting across the table on the same framework lot.

They publish: The group describes itself as the UK's largest specialist bid writing group, with a 76-strong team, bringing together bid writing, tendering, procurement and bid software.

Thornton & Lowe vs Glaxtons

2009, by Dave Thornton · Bolton

Thornton & Lowe is the most visible bid writing brand in UK organic search, so most buyers meet them first. People arrive here either because they want a second quote, because the merger has prompted a review, or because they want a firm with deeper specialism on one named framework rather than broad coverage.

They publish: Thornton & Lowe publishes a win rate of over 75 percent and states it completes more than 400 bids and tenders a year across sectors from construction to healthcare.

Executive Compass vs Glaxtons

2009, by Neil Capstick · Newcastle and the North East

Executive Compass and Glaxtons are compared most often by SMEs making a first serious framework application, where the decision is between a large established consultancy and a smaller specialist firm. The July 2026 merger has increased that comparison traffic, because clients want to know whether the firm they chose is still the firm they are buying.

They publish: Executive Compass publishes an 85 percent success rate, states it has supported thousands of SMEs and multinationals since 2009, and states it uses only directly employed writers rather than associates or freelancers.

Hudson Succeed vs Glaxtons

Part of the Hudson group of procurement businesses · United Kingdom

Hudson bundles tender search, bid writing and outsourcing, so buyers usually arrive comparing a bundled subscription against buying bid writing on its own. The question is whether you want the pipeline and the writing from the same supplier.

They publish: Hudson Succeed publishes an 87 percent win rate across all sectors and states it supports clients across construction, healthcare, facilities management, technology, professional services and logistics.

Kittle Group vs Glaxtons

Supporting clients since 2014 · United Kingdom

Kittle sits in the same mid-market bracket as Glaxtons, so the comparison is usually genuinely close and comes down to sector fit and who is actually doing the writing.

They publish: Kittle Group states it has supported clients with bids since 2014, ranging from small family-run enterprises to global industry leaders.

Neuven vs Glaxtons

Part of the Neuven group; the consultancy states it has operated for over a decade · United Kingdom

Neuven's centre of gravity is workforce compliance and audit rather than bidding, and the bid team sits alongside it. An organisation already using them to audit agency staffing or manage a neutral vendor arrangement meets the bid people through a relationship that already exists, which is a warmer route to a bid instruction than any search result. If that is how you found them, you are not really comparing two bid consultancies.

They publish: Neuven Consult publishes a 98 percent success rate on bid management and states it has secured over £25 billion in frameworks for its clients. It describes itself as the UK and Ireland's most successful neutral and independent consultancy. On the question of guarantees it says, in its own words, that it cannot provide guaranteed success.

Five questions that separate bid consultancies

  1. Who actually writes this? Name the individual, and tell me what else they are working on that month. Capacity dressed as expertise is the most common disappointment in this industry.
  2. Show me a bid you lost. And what you changed afterwards. The answer reveals more about how a firm works than any percentage.
  3. What would make you tell me not to bid? A consultancy that has never talked a client out of a submission is selling volume.
  4. Do you, or any group company, advise competitors bidding this lot? Newly relevant since the July 2026 consolidation. Get the answer in writing.
  5. What exactly is fixed in the fee? Clarification responses, portal uploads, redrafts after client review, and standstill queries are where quoted fees quietly become variable ones.

On our own numbers: Glaxtons publishes a 93 percent success rate across more than 500 submissions between 2022 and 2025, and £500M-plus won for clients. Like every figure in this industry it is self-reported and unaudited, and you should treat it the same way we have asked you to treat everyone else's.

Choosing a bid writing company: common questions

Who are the main bid writing companies in the UK?

The most visible specialist consultancies are Thornton & Lowe and Executive Compass, which merged on 29 July 2026 to form the Procurement Growth Group, alongside Hudson Succeed, Kittle Group and Glaxtons Consulting. The market also includes a long tail of freelance bid writers and generalist management consultancies that write bids as a sideline. The right choice depends far more on whether you need framework specialism or tender volume than on which firm is largest.

What changed when Thornton & Lowe and Executive Compass merged?

On 29 July 2026 the two firms came together under the Procurement Growth Group, described as the UK's largest specialist bid writing group with a 76-strong team. Dave Thornton became Group CEO, Neil Capstick Group Strategy Director and Christian Rowe Group Commercial Director, with both firms keeping their own managing directors. For clients, the practical questions are continuity of the named writer, pricing, and whether group companies may now advise competing bidders on the same framework lot.

How do I compare bid writing win rates?

Carefully, because none of them are independently audited. Published figures range from around 75 to 93 percent across the main UK consultancies, including our own 93 percent, but the denominators differ: some count every submission, some count only completed engagements, some exclude bids the client abandoned. A more useful test is to ask each firm to name the individual who will write your submission, what else they are working on that month, and to describe a bid they lost and what they changed afterwards.

Should I use a large consultancy or a specialist firm?

Volume decides it. If you submit many mid-value tenders across unrelated sectors, a large consultancy with a deep writer pool has capacity a smaller firm cannot match, and that is the right answer. If a small number of high-stakes framework applications determine several years of revenue, depth on those specific agreements matters more than headcount. Be honest about which of those two businesses you are, because the wrong model wastes a quarter either way.

What questions should I ask any bid consultancy before signing?

Five that reliably separate firms: name the person who will write this and what else they have that month; show me a bid you lost and what changed afterwards; what would make you tell me not to bid; do you or any group company advise competitors bidding this same lot; and what exactly is fixed in the fee. Any consultancy that cannot answer the fourth question directly, including after the July 2026 consolidation, is worth pressing on.
