Not a Software Business.
Not a Volume Practice.
We do not sell licences, manage designs or represent contractors. We are an independent UK construction cost consultancy working at senior level, exclusively on the client side.
What are your needs?
Not a Software Business
We do not sell BIM licences or quantity take-off tools. We use technology purely as a means to an end. What we sell is judgement built on solid senior commercial experience.
Not a Traditional QS
We do not measure quantities at tender and return at final account. The gap between those two moments is where most cost problems are created and where we add most value.
Not a Volume Practice
We work on fewer projects, at senior level, with full engagement across the whole of the UK. If you need a junior resource to populate a spreadsheet, we are the wrong firm for the job.
Not a Claims Consultant
We work upstream - building the commercial foundations that make disputes less likely. When projects reach final account, we have the records to support a rigorous position.
What We Are and
What We Are Not
Clarity about what we do starts with clarity about what we do not do. We are not cheap, not offshore and not generalist. Moreover, we do not design, manage construction or hold contracts with suppliers.
However, what matters more than what we are not is what we are. Reltic is an independent UK construction cost consultancy working at senior level, exclusively on the client side.
What We Are
An independent UK construction cost consultancy. Senior level. Client side. Across the full project lifecycle from feasibility through to final account settlement.
What We Do
Quantities, cost data and commercial decisions that are traceable, auditable and defensible. On residential and complex schemes across the UK.

Construction value advised
Client-side only
No contractor relationships
Feasibility to final account
The Projects Where Knowing What We Are Not Matters
High-End ResidentialHigh-End Residential Projects
High‑value residential schemes need tight coordination between design intent, programme and commercial control.
Digital construction analysis gives early visibility of quantity assumptions, procurement exposure and delivery risks before construction begins.
Typical commercial pressures
- Complex coordination between multiple trades
- Programme constraints on tight, complex sites
- Cost plans based on incomplete design information
- Contractor pricing volatility
Complex Phasing Projects
Phased construction programmes need disciplined coordination between sequencing, access, logistics and commercial risk.
Digital construction analysis exposes assumptions, procurement exposure and delivery risks across phases before work starts.
Typical commercial pressures
- Programme instability across phased construction
- Site logistics constraints and delivery sequencing
- Coordination between contractors and trades
- Late-stage variation exposure across phases
Mixed-Use Developments
Mixed‑use developments demand precise coordination between different asset classes, programme logic and commercial control.
Digital construction analysis highlights cost, procurement and delivery risks across uses before construction begins.
Typical commercial pressures
- Coordination between retail, residential and other uses
- Programme sequencing where uses open at different times
- Procurement exposure across many specialist packages
- Cost planning complexity as value and spec vary by use
When quantities are established independently, traced to the model and documented from the start, the final account is not a negotiation. It is a reconciliation.
That is the difference between a cost plan that holds and one that does not.
Numbers That Cannot Be Challenged
Do Not Need to Be Defended.
When you engage a firm that is not a software vendor, not a volume practice and not a claims consultant, you get something different. You get a commercial partner whose only brief is to make sure the numbers are correct.
That is the difference between a consultancy that tells you what you want to hear and one that tells you what the numbers show.
Fewer Projects. Senior Level.
Full Engagement Every Time.
› No software, no licences, no conflicts of interest
› Senior-level engagement on every single project
› Every position traceable, auditable and defensible
Independent Commercial Control. From First Cost Plan to Final Account.
We are not the right firm for every project. We are the right firm when the commercial risk is serious, the numbers need to be correct and someone needs to stand behind them.
