Construction cost consultancy in St Albans and Hertfordshire

Budgets, cost plans, tender reviews and cost reporting for residential and development projects, from a team that builds as well as advises.

Who it’s for

A clear commercial picture at each stage

A budget is only useful when everyone understands what it includes. Our cost consultancy helps clients review scope, compare quotes and understand what each decision will cost.

We can help with an early proposal, a tender or a project already on site. We agree what information we need, what the advice is for and how we will report, and we make clear that an early allowance is not a final construction price.

01

Budget and cost planning

We build a budget from your brief and drawings, and show which costs are firm and which are still estimates.

02

Tender and procurement review

We compare builders’ quotes line by line, not just the totals, and point out anything missing that makes one look cheaper than it is.

03

Change control

We price changes before you commit to them and keep a record of every agreed change.

04

Commercial reporting

Regular cost reports show what has been spent, what is committed and what is left. We can also help agree the final account.

We agree what the advice covers and how often we report before we start. To get going, send us the drawings and any quotes you already have.

Our process

How our cost consultancy works

Cost advice is only as good as the information behind it, so we start by reviewing what you have.

Define the question

Tell us where the project is and what decision you need to make.

Review the evidence

We go through the drawings, specification and quotes.

Explain the options

We explain the risks and differences in plain English.

Keep decisions visible

We keep the numbers up to date as the project moves on.

Greencroft Gardens involved a townhouse conversion with underpinning, substantial steelwork and additional floors. It shows the questions a good cost plan has to answer: what is included, where one trade’s work meets another’s and which decisions could change the scope.

Cost consultancy FAQs

Need advice on your specific project? Talk to the JBP team.

Can you give an accurate price from a floor area alone?

Only a rough one. Floor area doesn’t tell us about the structure, access, specification or condition of the building. We always tell you what a figure is based on.

Can you review builders’ quotations?

Yes. Send us the drawings, specification and quotes, and we’ll compare them like for like.

Will value engineering reduce quality?

It shouldn’t. Value engineering means finding better-value alternatives that still perform, look right and are easy to maintain, not just picking the cheapest option.
