Setting Out Engineer Day Rates: UK vs London 2025
A comprehensive guide to what setting-out engineers charge across the UK and London — covering day rates, IR35 status implications, and contractor budgeting tips.
London Day Rates
| Experience Level | London Day Rate (ex VAT) | Regional UK | | --- | --- | --- | | Junior/Entry | £250–£300/day | £200–£270/day | | Experienced (5+ years) | £350–£450/day | £280–£330/day | | Specialist (RC frames, complex) | £395–£500/day | £300–£380/day | | Night/Weekend premium | +20–30% | +15–25% |
London rates are 25–35% higher than regional UK due to site complexity, access constraints, and demand. Central London commands the top rates. Regional UK engineers in Manchester and Birmingham charge £250–£330/day for experienced operators.
Project-Based Estimates
| Project Type | Typical Duration | Estimated Cost (ex VAT) | | --- | --- | --- | | House extension foundations | 0.5–1 day | £350–£500 | | Groundworks/drainage | 1–2 days | £350–£700 | | Full new-build (3-bed house) | 3–5 days | £1,050–£1,750 | | RC frame (multi-storey) | 4–7 days | £1,400–£3,000+ | | Measured building survey setting out | Varies | From £800 |
All rates include calibrated total station, laser level, staff, and travel within Greater London. Confirm exact inclusions when booking.
IR35 Status: What Contractors Should Know
Inside IR35 (PAYE/Umbrella)
- Tax and NICs deducted at source
- Client provides equipment and sets hours
- Engineer is fully integrated into your operations
- Typical rate needed: £650/day to match outside-IR35 net income
Outside IR35 (Limited Company/Self-Employed)
- Engineer provides own calibrated equipment
- Greater autonomy over method and timing
- Can send a qualified substitute if unavailable
- Typical rate: £550/day (lower gross needed to achieve same net)
- Corporation tax and dividend tax treatment applies
What Determines IR35 Status?
| Factor | Outside IR35 | Inside IR35 | | --- | --- | --- | | Control | Engineer decides how/when work done | Client controls hours/method | | Substitution | Can send qualified replacement | Personal service required | | Mutuality of obligation | Engineer not obligated to accept every engagement | Must accept offered work | | Equipment | Engineer's own calibrated kit | Client provides instruments | | Integration | Not embedded in client team | Fully integrated |
Critical: 48% of engineering roles are classified inside IR35. Confirm status before agreeing terms. Speak to a contractor accountant if unsure.
Negotiating Multi-Week Contracts
- Offer longer engagements to secure 10–20% discounts on day rates
- Clarify scope upfront — avoid scope creep and last-minute additions
- Fix deliverables (as-built drawings, QA reports, frequency) in the contract
- Confirm IR35 status — inside/outside affects net income and employer NICs
- Equipment responsibility — who brings what, and what consumables are reimbursable
- Payment terms — agree invoicing cadence and payment terms upfront
London vs Regional: Key Differences
| Factor | London | Regional UK | | --- | --- | --- | | Day rate | £350–£500/day | £280–£380/day | | Access complexity | High (congestion, parking, restrictions) | Lower | | Site types | RC frames, basements, listed buildings | Residential, commercial | | Equipment | Specialist kit often required | Standard total station sufficient | | Travel | Congestion/ULEZ charges apply | Reimbursed separately | | Availability | High demand — book ahead | Generally available short-notice |
What to Budget For Your Project
For a typical London house extension or small commercial project, budget £350–£450/day for an experienced setting-out engineer. For complex RC frames or multi-storey projects in London, plan £400–£500/day. Inside-IR35 contractor budgets should allow for employer NICs on top of the day rate.
Frequently Asked Questions
Q: What IR35 status should I offer a setting-out engineer?
Outside IR35 is typically better for the engineer — they bring their own equipment and work autonomously. Inside IR35 suits roles that are fully integrated into your site team. Discuss with a contractor accountant to structure the engagement correctly.
Q: What does the day rate include?
Day rates typically include the engineer, calibrated total station and accessories, laser levels, staff, travel within Greater London, and QA documentation. Confirm exact inclusions when booking.
Q: How far in advance should I book?
Book a few days ahead for standard projects. For specialist RC frame or listed building work, allow extra lead time. Short-notice and next-day availability may be possible — contact us to check.
Q: What documentation should I require from a setting-out engineer?
As-set-out drawings (DWG), QA records, level schedules, photographs, and method statements. For building control sign-off, require a signed-off setting-out report.
