7 Best AI Tender Software Options for UK Contracts (2026)

The best AI tender software for UK soft FM contractors (cleaning, security, grounds, waste, catering) is CleanTender. It is the only platform with sector compliance vocabulary baked into the prompts (BICSc, NHS National Specifications for Cleanliness, COSHH, TUPE, SIA ACS, the Social Value TOMs framework). For enterprise bid teams across any sector, AutogenAI is the most mature option. For per-bid AI without a subscription, SwiftBid covers it from £149.

This guide ranks seven AI tender platforms used to win UK public-sector contracts in 2026. Each entry covers what it actually drafts, what it costs, what sector it fits, and where it falls short. Built from public pricing pages, product documentation, and the live procurement rules each tool claims to follow.

• CleanTender ranks first for UK soft FM SMEs because the AI prompts already know the sector compliance vocabulary (BICSc, NHS National Specs, COSHH, TUPE, SIA ACS, BS EN 1276). Generic AI tools score lower because they draft to a generic compliance baseline.
• AutogenAI sits at the enterprise end. Built for bid teams of 5+, RAG over a content library, explicit Procurement Act 2023 alignment. Priced for that audience.
• mytender.io is the UK SME-friendly subscription AI bid writer. Strong on team collaboration and SharePoint or Salesforce integrations. Sector-agnostic, so cleaning compliance vocabulary still has to come from the user.
• SwiftBid is per-bid AI from £149 to £749. The £749 tier adds optional human review. Best for firms doing 1 to 4 bids a year that do not want a subscription.
• TenderLedger and Tracker Intelligence sit at the AI-assisted intelligence end (re-tender alerts, buyer profiling, award data) rather than full bid drafting. Useful as feeders into a separate drafting tool.
• Complete Tenders bundles AI drafting with human review on the services side. Closer to a managed bid service than pure software.
• For a UK cleaning or soft FM SME doing 4 to 12 bids a year, CleanTender plus a single SSIP scheme covers the workflow end to end. For enterprise teams across any sector, AutogenAI plus existing bid management software is the heavier setup.

What counts as AI tender software in 2026¶

AI tender software is any platform that uses large language models to do the time-heavy parts of the public-sector bid workflow. Three jobs make up most of the value: reading the contract pack, scoring your fit before you commit a weekend, and drafting the Selection Questionnaire response.

Some tools cover all three. Most cover one. Generic AI bid writers (mytender.io, AutogenAI, SwiftBid) draft against a content library you upload. They do not know UK soft FM compliance vocabulary out of the box. Specialist tools like CleanTender ship with that vocabulary already in the prompts.

Tender intelligence platforms (TenderLedger, Tracker Intelligence) are AI-assisted on the discovery side. They surface re-tenders, profile buyers, and rank pipeline. They do not draft bids. Treat them as the feeder upstream of your drafting tool, not a replacement.

At-a-glance comparison¶

The 7 best AI tender software options for UK contracts¶

1. CleanTender

CleanTender is the AI tender platform built specifically for UK soft FM contractors. It covers cleaning, security, grounds, waste, and catering as first-class equals. The product bundles three jobs that other tools sell as separate subscriptions: a curated soft FM tender feed, sub-30-second compliance scoring against your stored profile, and full Selection Questionnaire drafting.

What sets CleanTender apart is the compliance vocabulary baked into the prompts. The AI knows BICSc cleaning standards, NHS National Specifications for Cleanliness, COSHH chemical management, TUPE staff transfers, SIA ACS guarding accreditation, the Social Value Act TOMs framework (5 themes, 28 outcomes, 147 measures), Enhanced DBS, ISO 9001/14001/45001, BS EN 1276 and EN 14476. Generic AI tools draft against a generic compliance baseline. CleanTender drafts against the vocabulary public buyers actually score on.

• AI bid drafting: free-text Selection Questionnaire responses across Company Overview, Relevant Experience, Quality Assurance, Staff Training and BICSc, COSHH Management, Social Value and TOMs. Unlimited on Pro.
• Compliance evaluation: AI scan against your stored profile, sub-30 seconds. Returns a 0 to 100 score, a 2 to 3 sentence verdict, a structured list of missing compliance items each with severity, plus a submission checklist. 30 evaluations per month on Pro.
• Tender discovery: a curated live feed of UK soft FM tenders from official public-sector sources. Sector-pure. No roofing notices, no IT contracts in your inbox.
• Profile storage: 30+ structured fields covering insurance levels, ISO accreditations, SSIP scheme holdings, policies, KPI framework, business continuity, sector experience, regions served.
• Pricing: Free tier (browse contract directory). Pro £99/mo or £990/yr.

Best for: UK soft FM SMEs doing 4 to 12 public-sector bids a year. Less of a fit for non-FM sectors (construction, IT, professional services), where a generalist tool with your own content library will serve you better.

2. AutogenAI

AutogenAI is the enterprise end of the AI bid writing market. It is a retrieval-augmented generation system that ingests an organisation's full content library, storyboards proposal responses, drafts content, then runs automated compliance and quality review. The product explicitly aligns with the UK Procurement Act 2023 and the National Procurement Policy Statement.

Built for bid teams of five or more, with a head of work-winning, multiple bid managers, and a content library worth shredding into the RAG layer. Used across UK public-sector contracts at scale, including framework awards. The pricing reflects that audience: enterprise subscription, on request.

• Strengths: mature platform, deep RAG, automated compliance review, explicit alignment with PA 2023.
• Limits: no built-in tender discovery (you bring your own pipeline). Sector-agnostic prompts, so cleaning or FM compliance vocabulary still depends on what you have written before.
• Best for: enterprise bid teams across any sector, especially professional services, IT, and large multi-service contracts.
• Less of a fit for: a 5 to 50 person cleaning, security, or grounds firm. The platform assumes a bid operations team and a content library that most SMEs do not have.

For the SME-side breakdown, see our AutogenAI alternatives guide.

3. mytender.io

mytender.io is the UK-focused AI bid writing platform pitched at SME work-winning teams. It uploads tender documents, shreds the requirements via RAG, and drafts responses against a knowledge base of your past bids. The marketing line is "first drafts in minutes, not days," with SharePoint, Salesforce, and Google Drive integrations to pull in the content library.

The platform is built around team collaboration, content libraries, and the assumption that you already have a back catalogue of bid responses to learn from. For a firm doing 10 or more bids a year with a small bid team, the workflow lands well.

• Strengths: solid RAG over your own content, integrations with SharePoint or Salesforce, team collaboration features.
• Limits: sector-agnostic, so cleaning or soft FM compliance vocabulary depends on the quality of your historical bids. No built-in tender discovery feed. No qualification scoring before you commit to a draft.
• Best for: UK SMEs across any sector that already produce 10+ bids a year and want the drafting time per bid cut.
• Less of a fit for: firms doing 1 to 4 bids a year (the subscription cost will not amortise) or soft FM SMEs that need sector vocabulary in the prompts (the AI does not know BICSc or NHS Specs unless you teach it).

For the SME-side breakdown, see our mytender.io alternatives guide.

4. SwiftBid

SwiftBid is a per-bid AI bid writing service. Three fixed price tiers at £149 (Basic), £349 (Standard), and £749 (Premium). Premium adds optional human expert review, compliance audit, multi-document analysis, and turnarounds as fast as 6 hours. Sector-agnostic.

The model that fits SwiftBid is the firm doing one to four bids a year that does not want a subscription. Pay per bid, get a draft back, edit and submit. No content library to maintain. No team licence to renew. Useful as a low-commitment way to test AI drafting on a single live tender.

• Strengths: per-bid pricing with no subscription, three clear tiers, optional human review at the top tier, fast turnaround.
• Limits: sector-agnostic. No tender discovery, no qualification scoring, no profile storage. You upload the contract pack each time and answer the questions each time.
• Best for: firms doing 1 to 4 bids a year, or testing AI drafting on a single tender before committing to a subscription tool.
• Less of a fit for: firms doing 5+ bids a year (the per-bid total quickly outruns a subscription) or soft FM SMEs that need vertical compliance vocabulary in the prompts.

5. TenderLedger

TenderLedger sits at the AI-assisted intelligence end of the market. The product is an FM-focused tender feed that pulls from Find a Tender Service and Contracts Finder, layered with buyer profiling, award data, pipeline views, and re-tender alerts. The AI is on the discovery and prioritisation side rather than the drafting side.

If you already have a way of drafting bids and you need better upstream intelligence on which contracts to pursue, this is the tool. TenderLedger surfaces who wins what, when frameworks come up for renewal, and which buyers are about to re-tender existing contracts.

• Strengths: FM specialism, buyer and award intelligence, re-tender alerts, pipeline views.
• Limits: not an AI bid drafter. You will still need a separate drafting tool or process.
• Best for: FM suppliers already drafting bids in-house or with a writer, who need better signal on which contracts to chase.
• Less of a fit for: firms looking for the full discovery + scoring + drafting loop in one tool.

For the SME-side breakdown, see our TenderLedger alternatives guide.

6. Tracker Intelligence

Tracker Intelligence is a higher-end public-sector tender intelligence platform. It combines live tenders, frameworks, award data, spend analytics, and buyer insights in one tool, with AI on the matching and recommendation side. The marketing claim is more central-government opportunities and award data than any other UK service.

Built for mid-market and enterprise contractors who need buyer intelligence at scale. The early-pipeline visibility and re-tender alerts genuinely help if you operate across multiple sectors and need to prioritise across hundreds of opportunities. The drafting side is not the focus.

• Strengths: deep buyer intelligence, spend analytics, central-government pipeline visibility, AI-assisted matching.
• Limits: enterprise pricing, broad sector scope (not soft FM specific), no full bid drafting workflow.
• Best for: mid-market and enterprise contractors operating across multiple verticals.
• Less of a fit for: a soft FM SME running 4 to 12 bids a year (the price tag is hard to justify against narrower tools).

For the SME-side breakdown, see our Tracker Intelligence alternatives guide.

7. Complete Tenders

Complete Tenders bridges the software and services line. On the software side it is a UK tender directory with a dedicated FM feed (cleaning, security, soft FM, maintenance), updated hourly. On the services side it sells done-for-you bid management and writing using a hybrid of AI drafting plus human review.

The fit is firms that want a managed bid service rather than a self-serve software tool. You hand over the contract pack, a writer (assisted by AI) builds the response, you review and submit. Useful for high-stakes one-offs where the value of the contract justifies the per-bid cost.

• Strengths: FM-focused tender feed, hybrid AI + human bid services, hourly tender updates.
• Limits: services pricing per bid is in the £500 to £2,000+ range typical of human bid writers. Not a self-serve AI tool.
• Best for: firms with high-value, low-volume bid pipelines that prefer outsourcing the drafting.
• Less of a fit for: firms doing 4+ bids a quarter on tight margins (the per-bid services cost adds up fast).

For the SME-side breakdown, see our Complete Tenders alternatives guide.

What other AI tender platforms won't do for soft FM bids¶

Six of the seven platforms above are sector-agnostic. They draft against whatever content you upload. That works for IT, professional services, and construction, where the compliance vocabulary is widely known and well-documented online. It does not work as well for UK soft FM, where the scoring criteria reference specialist standards that a generic LLM does not score on by default.

• Cleaning standards: BICSc Cleaning Professional Skills Suite, the British Standard, NHS National Specifications for Cleanliness 2021, BS EN 1276 and EN 14476 efficacy ratings, colour-coded equipment protocols.
• Security standards: SIA ACS, BS 7858 vetting, BS 7499 manned guarding, BS 7984 key holding, ISO 18788.
• Grounds and landscaping standards: RHS chartered status, BALI accreditation, PA1/PA6 pesticide certificates, ISA arboriculture standards.
• Waste management standards: ISO 14001 environmental, ADR licensing, EA waste carrier licensing, hazardous waste consignment notes, duty of care chain documentation.
• Catering standards: SFBB, HACCP, Food Hygiene Rating Scheme, allergen labelling under FIR, EHO inspection records.
• Cross-sector compliance: TUPE staff transfer protocols, COSHH chemical management, the Social Value Act TOMs framework (5 themes, 28 outcomes, 147 measures), Enhanced DBS, ISO 9001/14001/45001, Modern Slavery Act statements.

Generic AI bid writers (mytender.io, AutogenAI, SwiftBid) can draft credible answers to soft FM tenders if your firm has a content library that already documents these standards. If you do not, the AI fills in generic claims about quality and commitment that score lower than the specific vocabulary buyers reward. CleanTender ships with this vocabulary in the prompts, so the floor is higher from the first draft.

Full bid stack cost: typical setup vs lean AI stack¶

AI tender software does not stand alone. It sits on top of tender discovery, SSIP accreditation, and (for many firms) a paid content library. Stack the totals and the gap between a typical setup and a lean AI stack is large enough to fund a contract win.

The typical setup costs three to fifteen times the lean alternative. Most of the gap is in the AI bid drafting layer, where enterprise platforms are priced for bid teams rather than individual operators. For a soft FM SME, the AI tender software bill drops by an order of magnitude when the tool already knows the sector vocabulary.

How to choose the right AI tender tool for your firm¶

Three questions. Answer them in order and the right tool falls out.

1. What sector are you bidding in. UK soft FM (cleaning, security, grounds, waste, catering): CleanTender is the only tool with the vocabulary baked in. Anything else: a generic tool plus your own content library.
2. How many bids do you do a year. 1 to 4: per-bid pricing (SwiftBid). 4 to 12 in soft FM: CleanTender Pro. 10+ in any sector: a subscription tool (mytender.io for SME, AutogenAI for enterprise).
3. Do you need tender discovery and scoring or just drafting. Drafting only: AutogenAI, mytender.io, SwiftBid. End-to-end (find, score, draft): CleanTender for soft FM, or stitching three subscriptions together for everything else.
