House extension under construction with scaffolding to the rear elevation

For homeowners building, extending or refurbishing

A quantity surveyor on your side of the build

Building or rebuilding a home is often the largest contract a family ever signs, usually with less protection than a developer would accept. We give you the same commercial control.

The problem

Where home projects go over budget

It rarely happens in one moment. It happens in small steps nobody is checking.

Point 01

A price with gaps

A builder’s quote can look complete and still leave out work that will come back later as extras.

Point 02

A contract that says little

Payment, changes and completion are often vague, and vague terms favour whoever is holding the money.

Point 03

Paying ahead of the work

Payments based on what is promised rather than what is built leave you exposed if the job stalls.

Point 04

Extras agreed on site

Small changes agreed in conversation add up, and arrive together at the end.

Services

How we protect your budget

Service 01

Builder’s quote check

We review the price line by line and tell you what is missing, what is high and what is likely to come back as an extra.

Service 02

Comparing quotes

We put two or three quotes on the same basis, so you compare like with like rather than headline totals.

Service 03

Contract review

We make sure what you sign says what you think it says: payment, changes, completion and retention.

Service 04

Monthly valuations

Each month we value the work actually in place, so you pay for what has been built.

Service 05

Changes and extras

Every extra is tested against the contract before you agree to pay it.

Service 06

Final account and disputes

We close the account on evidence, and support you if it turns into a dispute.

Timing

The best moments to call

  1. 01

    Before you choose a builder

    When the price can still change.

  2. 02

    Before you sign

    When the contract can still change.

  3. 03

    During the build

    Monthly, before each payment.

  4. 04

    When something goes wrong

    A dispute over extras, delays or the final bill.

Terms

How we take the work on

On your side only

We do not work for your builder on your project, and we take no commission from anyone. If we have acted for a party on your project, we tell you before we start.

How we charge

A quote check or contract review is a fixed fee. Support through the build is usually a fixed monthly fee or a percentage of the build cost. The basis is agreed in writing before anything begins.

Questions

Before you instruct

I am a homeowner. Can you check my builder’s quote?

Yes. That is one of the most useful moments to bring us in, because the price is still open to change.

Is my project too small for you?

Tell us what it is. If it is not work we should take, we will say so and point you somewhere sensible.

Do I need an architect as well?

Usually yes for design and planning. We do not design. We look after the money and the contract.

The build has already started. Is it too late?

No. We can start at any monthly payment, and earlier problems can often still be addressed.

Do you work outside London?

Yes, across the United Kingdom.

Clients

Who else we work with

We act for one party on each project. Never two sides of the same build.

01

Main contractors and subcontractors

Senior QS capacity without a full-time hire. Applications, variations and final accounts, prepared so they stand up when the other side checks.

02

Property developers

Cost certainty before the scheme is committed, and a defensible position later on, when the numbers are challenged by a contractor or a funder.

03

Funders and lenders

Independent appraisal, drawdown certification and monthly progress reporting, written to be read by a credit team, and not by another surveyor.

04

Private investors and family offices

Commercial oversight on schemes where the exposure is direct, the margin for error is small and nobody else is testing the numbers for you now.
