Tender Documents and the Procedure for Tendering

Written for the UK scenario, but the principles apply in most English-speaking nations.

The first time a small trade business downloads a tender pack, it can be a shock. A simple job, such as maintaining a council’s grounds or rewiring a block of flats, can come with half a dozen documents, a long questionnaire and strict rules on how to reply.

The good news is that almost every tender pack is built the same way. Once you know what each document is for and what the buyer wants from you, completing one becomes a methodical job rather than a mystery. This guide explains what tender documents and the procedure for tendering are, and what you will find in a typical pack, and how to complete them without losing marks on avoidable mistakes.

What is a tender document?

A tender document is the set of papers a buyer issues when it wants businesses to bid for a contract. It tells you what the buyer wants done, the rules for bidding, the contract you would be signing, and exactly what you must send back.

The word is used in two ways:

  • The buyer’s documents, often called the tender pack or invitation to tender (ITT). These are what you download and read.
  • Your response, sometimes also called your tender or bid. This is what you complete and return: your answers, prices and supporting documents.

Public bodies such as councils, housing associations, schools and NHS trusts use tenders because the law requires them to buy fairly and openly. Many larger private firms, such as main contractors and facilities management companies, use the same approach to choose subcontractors.

What is inside a typical tender pack

Names vary from buyer to buyer, but most tender packs contain these documents:

Document

What it is

What you do with it

Instructions to tenderers

The rules: deadline, how to submit, how to ask questions, how bids are scored

Read first. Breaking a rule can get your bid thrown out unread

Specification

What the buyer wants done, to what standard, how often and where

Read line by line. Your price and answers must cover all of it

Supplier questionnaire

Questions about your business: legal status, finances, insurance, health and safety, past experience

Answer every question and attach the evidence asked for

Quality questions

Questions on how you would do the work, each with a word limit and a score

This is where bids are won or lost. Answer the question asked

Pricing schedule

A form or spreadsheet for your prices, often per item, per visit or per year

Fill in every line. Don’t change the layout

Contract and terms

The contract you will sign if you win

Check payment terms, penalties and liabilities before you bid

Declarations and forms

Signed statements, such as no collusion and conflicts of interest

Sign and return every one

The instructions to tenderers will also tell you the evaluation criteria: how marks are split between price and quality, for example 60% quality and 40% price. That split tells you where to put your effort.

Procedure for tendering: step by step

  1. Decide whether to bid at all. Before you spend days on a tender, check you can meet every pass/fail requirement: insurance levels, accreditations, turnover, experience. If you can’t, don’t bid. Walking away from the wrong tender is a skill.
  2. Read everything before you write anything. Read the whole pack once, start to finish, with a highlighter. Note the deadline, the scoring split, the word limits and every document you must return.
  3. Make a checklist of what to return. List every form, answer, certificate and policy the buyer wants. Missing one document is the most common reason small firms are disqualified.
  4. Ask questions early. If anything is unclear, use the buyer’s clarification process before its deadline. The answers are usually shared with all bidders, and you may spot something your competitors haven’t.
  5. Gather your evidence. Insurance certificates, your health and safety policy, risk assessments, method statements, accreditations, accounts and references. Keep these ready in a folder so every future tender is quicker.
  6. Answer the quality questions properly. Answer exactly what is asked, in the order it is asked, using the buyer’s own words from the specification. Give specific examples from your past work, not general promises.
  7. Price the work from the specification. Work out the true cost of every item, including travel, materials, overheads and your profit. Don’t guess, and don’t price low just to win: a contract that loses money is worse than no contract.
  8. Check, then submit early. Check every document against your checklist, then submit at least a day before the deadline. Online portals close on the minute, and late bids are rejected.

Tender document example: a small grounds maintenance contract

Here is how a typical small tender might look. A district council wants a contractor to cut grass and maintain shrub beds at six small sites for three years.

  • Instructions to tenderers: bids through the council’s online portal by 12 noon on the closing date. Scoring is 60% quality and 40% price. Clarification questions must be asked at least seven days before the deadline.
  • Specification: grass cut fortnightly from March to October, to a set height, with cuttings removed from paths. Shrub beds weeded monthly. A site plan for each location.
  • Supplier questionnaire: company details, public liability insurance of at least £5 million, employers’ liability insurance if you have staff, a health and safety policy, and two references from similar work.
  • Quality questions: for example, “Describe how you will plan and deliver the service, including how you will cover staff absence and equipment breakdowns.” (Maximum 500 words, worth 20% of the marks.)
  • Pricing schedule: a price per cut for each site, and a yearly total.
  • Contract: payment 30 days after invoice, and the right for the council to deduct money for missed visits.

A strong answer to that quality question would name the mowers you use and your backup plan if one breaks, explain who covers if you are ill, and show how you schedule visits so no site is missed. A weak answer says “we are a reliable, experienced company committed to quality” and scores almost nothing.

Common mistakes that lose tenders

  • Missing a document. One unsigned declaration or missing certificate can disqualify the whole bid, however good the rest is.
  • Not answering the question asked. Evaluators score against a marking guide. If the question asks about staff absence and you write about your experience, you score low.
  • Going over the word limit. Words over the limit are often simply not read.
  • Copying and pasting from an old tender. Evaluators spot generic answers immediately, especially when they mention the wrong client or the wrong site.
  • Promises with no evidence. “We always use trained staff” scores less than “all our operatives hold [named qualification]; certificates attached”.
  • Changing the pricing schedule. Adding lines, rounding or leaving cells blank can make your price impossible to compare, and some buyers will reject it.
  • Pricing too low. Buyers increasingly reject prices that look too low to deliver the work. And if you win at a loss, you are stuck with it for the life of the contract.
  • Submitting at the last minute. Portal problems, slow uploads and a missing file at 11:55 are a common way to lose a tender you could have won.

If you lose, ask the buyer for feedback. Public buyers will normally tell you your scores and where you lost marks. It is free advice for your next bid.

Where to find tender documents

Under the Procurement Act 2023, which came into force in February 2025, public bodies publish their tender notices on Find a Tender, the government’s Central Digital Platform. It is free to use. You must register your business on it to bid, and since April 2026 even suppliers winning smaller, lower-value public contracts need to be registered.

Many councils and housing associations also use their own or regional tender portals, and some still list smaller opportunities on Contracts Finder. Check the procurement page of each council in your area and register for email alerts.

Frequently asked questions

What is the difference between a tender and a quote?

A quote is usually informal: you visit, price the job and send a figure. A tender is formal: the buyer sets the rules, the questions and the pricing format, and scores every bid in the same way.

Can a sole trader bid for tenders?

Yes. Many public contracts, especially smaller ones and those split into lots, suit sole traders and small firms. Check the minimum requirements first, such as insurance levels and turnover.

How long does it take to complete a tender?

A small, simple tender can take a day. A larger one can take a week or more. Having your policies, certificates and example answers ready in advance cuts the time dramatically.

Do I need accreditations to bid?

Not always, but schemes such as CHAS, SafeContractor and Constructionline are often asked for, especially by main contractors and housing associations.
