How to Price a Construction Tender in 2026: A Step-by-Step Guide for UK Builders

Pricing a construction tender in 2026 requires more than applying a broad rate per square metre. Labour, materials, plant, subcontractor costs, preliminaries, overheads and profit all need to be assessed against the project scope and current market conditions.

UK tender prices are forecast to rise by approximately 2.8% to 4.5% during 2026, depending on the sector, location, project type and level of risk. Material prices are also moving in different directions. Structural steel has seen sharp increases in some market data, including reported rises of around 17.7%, while concrete-related prices have been softer in some categories.

For contractors, the objective is to submit a competitive tender without accepting unnecessary margin risk. This guide explains a structured approach to construction tender pricing for UK builders and contractors.

What Should a Construction Tender Include?

A complete tender price usually includes:

The exact structure will depend on the procurement route, contract requirements and information provided.

A tender based only on drawings and a single overall allowance may leave important costs hidden. A structured estimate makes it easier to review the project, compare supplier quotations and identify areas of uncertainty.

STEP 1: REVIEW THE TENDER INFORMATION

Begin by collecting and reviewing all available project information.

This may include:

Check that the documents are current and consistent. Note any differences between drawings, specifications and schedules.

You should also identify:

If information is incomplete, record the issue and make a clear assumption or allowance. Do not treat uncertain information as a confirmed scope item.

A professional construction estimating service can help review the documents and identify the information needed before pricing begins.

STEP 2: PREPARE OR CHECK THE BILL OF QUANTITIES

A Bill of Quantities, or BOQ, is a measured schedule of the works required to complete the project.

It normally includes:

Item Description Quantity Unit Rate Total

A BOQ helps you price a defined scope instead of relying on visual judgement from drawings. It can also reduce the risk of missing smaller items that may become expensive once the project starts.

Where you already have a BOQ, check:

Where no BOQ exists, a detailed quantity take-off may be required first. Estimate Exact provides Bills of Quantities for UK builders and contractors, prepared from drawings, specifications and schedules.

STEP 3: BUILD UP LABOUR COSTS

Labour should be priced against the actual work involved rather than a broad project allowance wherever sufficient information is available.

For each work item, consider:

A basic labour calculation is:

Quantity ÷ expected output = labour hours required

You can then apply the appropriate hourly or daily labour rate.

Allow for the project location, trade availability, travel, accommodation, overtime and any specialist requirements. Labour shortages can affect both rates and programme. A low labour allowance may make the tender appear competitive but create a shortfall during delivery.

Labour should also be reviewed against the programme. A compressed programme may require additional labour, supervision, shifts or temporary facilities.

STEP 4: PRICE MATERIALS USING CURRENT INFORMATION

Material prices should reflect the expected procurement date and project requirements.

Use:

Avoid applying one blanket percentage to every material. The 2026 market is not moving uniformly.

For example:

If a project contains a significant steel frame, obtain current supplier information where possible. A reported increase of approximately 17.7% in structural steel should not automatically be applied to the complete tender. It should be tested against the actual steel specification, supplier quotations and expected delivery period.

Similarly, if concrete pricing has reduced in a relevant category, confirm that the reduction applies to the required grade, volume, location and delivery conditions.

STEP 5: INCLUDE PLANT AND EQUIPMENT

Plant costs are often missed or placed into a general allowance that does not reflect the programme.

Review the need for:

For each item, consider the hire period, mobilisation, demobilisation, operator requirements, servicing, fuel and potential extensions.

Longer programmes can increase plant costs even when the original scope does not change. Site access and restricted working areas may also require smaller or specialist equipment.

STEP 6: OBTAIN AND CHECK SUBCONTRACTOR PRICES

Subcontractor packages should be issued against a clear and consistent scope.

Your enquiry should identify:

Compare returned quotations carefully. A lower price may exclude items included by another subcontractor.

Check whether each quotation includes:

Where quotations are not available, include a realistic subcontract allowance and identify it as an assumption. Update the allowance if better information becomes available before tender submission.

STEP 7: ALLOW FOR PRELIMINARIES

Preliminaries cover the costs of managing and supporting the project. They should be linked to the programme and site requirements.

Typical items include:

A six-month project and an eighteen-month project will not have the same preliminaries cost. Review the expected programme, site constraints and client requirements before applying an allowance.

STEP 8: ADD OVERHEADS, RISK AND PROFIT

Once the direct costs have been built up, add the costs required to operate the business and deliver the contract commercially.

Business overheads

These may include:

Risk allowances

Consider risks such as:

Profit

Profit should reflect the project risk, contract terms, client requirements, workload and market conditions. A competitive tender should not be achieved by removing the allowance needed to manage identifiable risk.

The BCIS tender price index update for the second quarter of 2026 reported annual tender price growth of 3.2%. It also noted pressure from materials, skilled labour shortages, fuel, plant and supply-chain risk.

Use market forecasts as a reference point, not as a replacement for project-specific pricing.

STEP 9: TEST THE 2026 TENDER AGAINST DIFFERENT SCENARIOS

For projects with a long procurement or construction period, test the effect of different assumptions.

For example:

The Knight Frank 2026 tender price index forecast 3.3% tender price inflation for the UK and London. Other market forecasts provide a wider range, reflecting uncertainty around demand, labour, regulation, logistics and materials.

Record which scenario has been used and why. If the project is steel-intensive, infrastructure-related or based on early design information, the higher scenario may require closer consideration.

A SIMPLE TENDER PRICING EXAMPLE

Assume the following direct costs:

Direct cost subtotal: £1,650,000

You then add:

Illustrative tender total: £2,163,500

This is only an example. The correct allowances depend on the project scope, programme, contract and information available.

FAQs

What is construction tender pricing?

Construction tender pricing is the process of calculating the cost of delivering a defined construction project. It normally includes labour, materials, plant, subcontractors, preliminaries, overheads, risk and profit.

Should I apply one inflation percentage to the whole tender?

No. A general tender price allowance can provide a starting point, but materials and labour may move differently. Review steel, concrete, imported products and specialist equipment separately where appropriate.

Can Estimate Exact price an existing Bill of Quantities?

Yes. We can review and price an existing BOQ or prepare a new measured BOQ from your drawings and specifications.

What information do you need?

Ideally, send architectural and structural drawings, specifications, schedules, tender documents, programme information and any supplier or subcontractor quotations. If information is incomplete, we can identify assumptions and allowances.

Do you provide estimating services for builders across the UK?

Yes. Estimate Exact provides remote estimating support for builders, contractors, subcontractors and construction professionals throughout the UK.

How do I request a quotation?

Send us your drawings and tender documents. We will review the requirements and confirm the scope, fixed fee and expected delivery date before starting work.
