Commercial expertise
Practical commercial capability shaped by measured work, changing scope, payment cycles, subcontract interfaces and the reporting disciplines needed to keep projects commercially visible.
Experience indicators describe relevant prior and recent commercial experience; they do not guarantee any recovery, payment or project outcome.
Commercial pressure points
Commercial leakage rarely sits in one document. It develops across instructions, records, valuation, payment, cost and downstream commitments.
The project needs capable QS support now, but the requirement does not justify a permanent hire or a conventional full-time role.
Instructions and evolving scope are being delivered faster than the commercial record is keeping up.
Applications, assessment and payment positions are not giving management enough visibility.
The commercial position exists, but the documentary trail does not adequately demonstrate it.
Cost-to-complete, cash, margin and unresolved commercial items are not giving management one clear picture.
Upstream and downstream positions are moving out of alignment.
Haven Measure turns fragmented commercial information into a controlled set of priorities, records and management actions.

What Haven Measure offers
Choose by the result you need. Each route explains what it is, why clients use it, how it may help, what you receive and exactly how to begin.
Agency-engaged B2B delivery
Day rate discussed agreed for the specific opportunity
Flexible quantity surveying and commercial-management capacity for an agreed project phase or assignment, supplied through a Contracting Agency accepted by Haven.
Your project needs full-time, part-time or fractional commercial support without making a permanent hire.
Adds disciplined measurement, valuation, change, subcontract, forecast and reporting capability to day-to-day project delivery.
The outputs recorded in the Assignment Schedule, maintained commercial records, written reporting at the agreed cadence and completion handover.
Ask the proposed Contracting Agency to send the end client, project, location, pattern, hours, duration, responsibilities and required outputs. Haven then checks fit and agrees the rate and terms in writing.
The agreed assignment may include measurement, valuations, applications, change control, payment, procurement, subcontract commercial management, cost-to-complete, forecasting, cash and margin reporting, final accounts, commercial correspondence and meeting support. Only the responsibilities expressly recorded in the signed Assignment Schedule are included.
Outside IR35 intended basis only, subject to engagement-specific assessment and actual working practices. Haven contracts through a UK-established Contracting Agency accepted after checks. Invoice route: payment within seven calendar days of agency receipt. Agreed self-billing route: payment within seven calendar days of Haven submitting the completed weekly timesheet, with the corresponding self-billed invoice issued by the agency. Delayed approval, self-billing or end-client payment must not extend Haven's due date. Haven does not commission or pay for an external IR35 assessment.
Bespoke defined output
Bespoke quotation only by separate written agreement
A defined, project-specific quantity surveying commission undertaken by Haven Measure Limited only by separate written agreement.
You do not need ongoing QS capacity, but one work package or standalone commercial task needs completing.
Moves a specific measurement, valuation, change, account, procurement, forecast or reporting requirement towards a clear deliverable and handover.
A written scope and information basis, agreed assumptions, the named schedule, assessment, calculation or report, and identified completion actions.
Send a non-confidential description of the project or work package, the output required, available records and required timing. Haven checks competence, conflicts, PI position and professional risk before quoting.
Potential commissions include measurement or remeasurement, take-offs, valuation or application support, change and variation schedules, package-account reviews, tender or commercial comparisons, cost-to-complete or forecast work, final-account support and other precisely defined QS outputs accepted by Haven.
Haven performs the agreed QS work objectively as a separate consulting business exercising its own professional judgement.

The contracting route, fee, scope, reliance, exclusions and terms are agreed for each instruction.

Check Full Scan fitNo single public day rate is quoted because the commercial requirement changes with the role, responsibilities, hours per day, duration, location, travel and remote or hybrid split. The Haven rate, Contracting Agency margin treatment, expenses, invoicing cycle and notice provisions must all be recorded in writing. Haven Measure Limited is not currently VAT registered; no VAT is currently added.

How to engage Haven
Each service starts with a short non-confidential enquiry. Haven then confirms the correct scoping, contracting, payment and secure-information steps for that route.
Snapshot / Full Scan
Use the Fit Checker to compare the £495 Snapshot and £1,495 Full Scan against the number of issues and agreed record volume.
Share a non-confidential written summary. Do not attach contracts, drawings or project records at this stage.
Haven completes conflict, competence, professional-risk and scope checks, then issues the engagement terms and accepted scope.
The authorised client contact pays by business bank transfer using the private pro-forma details or, where enabled, by Stripe-hosted card checkout.
Verified payment unlocks that project's controlled upload area for the agreed contracts, drawings, valuations, registers, spreadsheets, correspondence, photos or relevant CAD files.
Haven checks the received pack and confirms in writing when it is complete. That written confirmation—not payment or upload—starts the delivery clock.
Independent QS Works
Send a non-confidential outline of the project, work package or commercial task, the output needed, available records and required timing.
Haven reviews competence, capacity, conflicts, professional risk, PI position, information needs and whether the task can be clearly bounded.
Haven issues a written proposal stating the task, information basis, assumptions, deliverable, programme, fee, contracting route and exclusions.
The instruction proceeds only after both parties agree the scope, responsibilities, payment arrangements and engagement terms in writing.
Project information is shared only through the secure route confirmed for the accepted commission. Haven checks the agreed inputs before delivery begins.
Haven completes the agreed QS work and supplies the named deliverable, assumptions, outstanding information points and completion handover.

Delivery begins only after written acceptance. Contract terms and actual working practices must remain aligned throughout.
A contractor chooses Snapshot or Full Scan and sends only a non-confidential summary. Haven checks fit, conflicts, scope, competence and professional risk. If accepted, Haven issues the written engagement documents, private pro-forma/payment request and a time-limited accepted-offer link. The authorised business contact pays 100% upfront by transfer into Haven Measure Limited's business account or, where enabled, through Stripe's hosted card checkout. Bank details are supplied privately and never published; Haven never receives full card details. Once cleared payment is verified, that project's controlled upload area opens. The client uploads only the agreed contracts, drawings, valuations, change registers, correspondence, spreadsheets, photographs or relevant CAD files. Haven then checks whether the information pack is readable, within scope and complete. The delivery clock starts only when Haven confirms that complete accepted pack in writing. The client receives the agreed colour-coded Risk Map and findings; no recovery, entitlement or outcome is guaranteed.

Frequently asked questions
Commercial answers first, with the important engagement safeguards kept clear and accessible.
Choose Contract Quantity Surveying for full-time, part-time or fractional QS/commercial capacity on a defined assignment through a Contracting Agency. Choose Independent QS Works when one specific work package or QS output needs completing under a bespoke written agreement. The Snapshot is for up to three selected concerns; the Full Scan supports a wider review of up to six agreed issues. The Fit Checker provides a provisional route before any project records are shared.
Contract QS outputs follow the Assignment Schedule and may include measurements, valuations, applications, change controls, procurement records, subcontract management, forecasts, reports and final-account actions. Independent QS Works provide the particular calculation, schedule, register, assessment or report stated in the bespoke scope, with its agreed basis and handover. A Snapshot or Full Scan provides the applicable Commercial Recovery & Risk Map, findings and action priorities. The signed terms always state the precise outputs.
They are defined, standalone quantity surveying commissions for clients who need one specific commercial task completed rather than ongoing QS capacity or a broad recovery review. Examples may include measurement, a valuation review, a change reconciliation, package-account work, tender comparison, cost or forecast reporting, final-account support or another accepted QS output. Each instruction is subject to Haven's written scope, competence, conflict, PI, reliance and professional-risk checks, bespoke quotation and engagement terms.
After Haven accepts fit, conflicts and scope and the client accepts the written engagement terms, the authorised business contact receives a private pro-forma/payment request and time-limited accepted-offer link. The £495 Snapshot or £1,495 Full Scan is paid 100% upfront by transfer into Haven Measure Limited's business account or, where enabled, by Stripe-hosted card checkout. Bank details are supplied privately and never published; Haven does not receive full card details. A price shown on this website or a completed Fit Checker does not itself accept an instruction.
A verified successful payment unlocks a project-specific controlled upload area. The client uploads only the agreed pack. Haven then checks scope, file readability and completeness. Payment, upload or submission does not start delivery; Haven's written confirmation that the accepted information pack is complete starts the applicable delivery period.
Haven does not publish a single day rate because each opportunity differs. The written rate reflects the remote, hybrid or site-based pattern; agreed working days and daily start/finish times; break basis; expected hours; any weekend or out-of-hours requirement; location and travel; duration; responsibilities; authority; project conditions and the role itself. The rate confirmed by Haven is the amount payable to Haven; any Contracting Agency margin or end-client charge must not reduce it. Travel, accommodation, expenses and additional hours are included only where expressly agreed. Different hours or working arrangements may require a different rate and are always subject to Haven Measure Limited's prior written agreement.
Contract QS assignments must be contracted through a UK-established Contracting Agency accepted by Haven after checks. Haven normally invoices weekly in arrears unless signed terms establish an agreed self-billing route. Under the invoice route, payment is due within seven calendar days of agency receipt. Under self-billing, payment is due within seven calendar days of Haven submitting the completed weekly timesheet and the agency issues the corresponding self-billed invoice. A specific factual query must be raised within two working days; unaffected time remains payable on the original date. Delayed signature, self-billing or end-client payment must not extend Haven's due date.
The signed agency contract and Assignment Schedule must identify the legal parties, end client, scope, responsibilities, authority limits, expected outputs, reporting cadence, working days and hours, remote/hybrid/site pattern, location, travel, rate, agency-margin treatment, expenses, invoice and payment process, notice, cancellation, extension, information and systems access, confidentiality, insurance and status responsibilities. No work begins until Haven accepts the complete written position.
No. It identifies selected factual record differences, commercial priorities and matters for further assessment. It is not legal advice or a determination of entitlement, breach, notice validity, limitation, waiver or prospects.
No. Recovery, saving, payment, settlement, outcome and timetable are not warranted or guaranteed. Values are client-stated or indicative commercial figures subject to evidence, contract, counter-position and specialist advice.
Written-first communication keeps scope, instructions, assumptions, decisions and outputs clear and traceable. Start through the enquiry composer, direct email or LinkedIn; project records are transferred only through the controlled route confirmed for an accepted instruction.
Yes, subject to availability and agreement, for a defined project phase or assignment with stated outcomes, responsibilities and an end point. Full-time, part-time and fractional describe service capacity only; they do not determine tax status or create employee-style control. The engagement must remain genuinely business-to-business, with actual working practices consistent with the written Outside IR35 intended basis.
No. Status is engagement-specific and depends on the whole contractual chain and actual working practices. The legally responsible party retains its statutory duties. If the end client or agency requires a paid independent assessment, that party must arrange and meet its cost; Haven will provide reasonable factual information but will not commission, reimburse or accept a deduction for the assessment, provide tax advice or guarantee the conclusion.
Not through the public enquiry or Fit Checker. Fixed-fee clients receive project-specific controlled upload access only after written acceptance, accepted engagement terms and verified payment. Independent QS Works use the secure transfer route confirmed for the accepted commission; Contract QS document access follows the accepted agency assignment arrangements. There is no anonymous file drop, public bucket or browsable client document list.

Professional safeguards
Detailed protections sit behind the commercial proposition so clients can understand both the value and the limits of the service.
QS administration boundary: where expressly scoped and authorised, Haven may prepare commercial correspondence, administer project notices, attend commercial meetings, negotiate commercial positions and undertake commercial measurement or progress verification. It does not warrant legal validity or timeliness, provide legal advice, perform reserved legal work or act as legal advocate.
Client responsibility: the client remains responsible for every contractual and statutory deadline, notice, decision and action. Dates reproduced from supplied material are not legally verified deadlines.
Contract QS safeguard: opportunities are considered on an Outside IR35 intended basis only, through a Contracting Agency accepted by Haven and subject to engagement-specific review, written terms and actual working practices. Labels, payment terms, day rates and assessments are not conclusive. Haven may decline, pause or re-scope an unsupported or changed arrangement.
Payment safeguard: the contract between the Contracting Agency and Haven must record payment within seven calendar days of agency receipt of Haven's invoice or, under agreed self-billing, of Haven submitting the completed weekly timesheet. Delayed approval, self-billing or end-client payment cannot extend the due date. Haven does not accept pay-when-paid terms and does not fund external status assessments.
Independent QS safeguard: an Independent QS Works instruction exists only within the separately signed scope. External objectivity does not create certifier, contract-administrator, expert, adjudicative or legal authority, and third-party reliance is excluded unless Haven expressly accepts it in the engagement terms.
Engagement gate: competence, conflicts, professional-indemnity position, governing law, secure transfer and written terms must be confirmed before records or instructions are accepted.
