What should be in a driveway quote, how to compare like with like, and questions to ask before signing.

Getting three quotes is standard advice, but comparing them isn't straightforward. A £5,000 quote isn't automatically better than a £7,000 one – it depends what's included. This guide helps you understand quotes and make fair comparisons.

What A Complete Quote Should Include

A professional driveway quote breaks down into several components:

1. Site Preparation

  • Removal and disposal of existing surface
  • Excavation depth
  • Skip hire or waste removal costs
  • Any additional digging (for drainage, etc.)

2. Base Construction

  • Sub-base material and depth (e.g., 150mm Type 1 MOT)
  • Base layer (tarmac depth or concrete thickness)
  • Compaction method

3. Edging And Borders

  • Type of edging (concrete, brick, aluminium)
  • Decorative borders if included
  • Any kerb work or threshold details

4. Surface Material

  • Product specification (brand, type, colour)
  • Coverage and depth
  • Pattern or laying method for blocks

5. Drainage

  • Linear drains included?
  • Connection to existing drainage
  • Soakaways if needed

6. Finishing

  • Manhole covers – replaced or "made good"?
  • Any walls, steps or retaining structures
  • Sealing (for block paving)
  • Clean-up and site clearance

7. Terms

  • Guarantee period and what it covers
  • Payment schedule
  • Start date and estimated duration
  • Insurance confirmation

Common Quote Comparison Traps

Different Base Depths

A quote with 100mm sub-base will be cheaper than one with 150mm, but the thinner base may fail sooner. Compare like with like.

Vague Material Specifications

"Block paving" could mean anything from budget concrete blocks to premium clay pavers. Ask for exact product names.

Excluded Items

One quote might include manhole replacement while another says "existing manholes made good". The difference can be hundreds of pounds.

Drainage Assumptions

Some contractors assume existing drainage is adequate. Others include new drains. Make sure you know what you're getting.

Different Site Assessments

If one contractor spotted that your existing base is failing while another plans to overlay it, their quotes will differ significantly – and so will the results.

Creating A Fair Comparison

To compare quotes properly:

Step 1: Get Detailed Quotes

Ask each contractor for an itemised breakdown. A single-line "new driveway – £6,500" isn't enough information.

Step 2: Check Specifications Match

Create a simple comparison table listing:

  • Excavation depth
  • Sub-base material and depth
  • Base type and thickness
  • Surface material (exact product)
  • Edging type
  • Drainage included
  • Manholes – replaced or made good
  • Guarantee period

Step 3: Adjust For Differences

If quotes differ on specifications, ask contractors to requote to match. Or add/subtract estimated costs to normalise the comparison.

Step 4: Check Credentials

The cheapest quote means nothing if the contractor can't deliver quality work. Check:

  • Portfolio of similar work
  • References or reviews
  • Insurance certificates
  • Trade body membership (not essential but reassuring)

Questions To Ask Before Signing

  • What's the sub-base depth and material?
  • What happens if you find problems once you dig (poor ground, roots, services)?
  • Are manholes being replaced with recessed covers or just worked around?
  • What's included in the guarantee, and who backs it?
  • What's the payment schedule?
  • When can you start, and how long will it take?
  • What's not included that I might assume is?

Red Flags In Quotes

  • Pressure to sign quickly – "This price is only good today"
  • Large upfront deposits – Materials deposit is reasonable, but 50%+ upfront is risky
  • No written quote – Everything should be documented
  • Vague specifications – Can't or won't tell you exactly what they'll do
  • No fixed address – Be wary of contractors without a traceable business location
  • Significantly cheaper than others – Often means cutting corners you won't see until later

Sample Comparison Table

Item Contractor A Contractor B Contractor C
Total price £6,200 £7,100 £5,400
Excavation depth 200mm 250mm 150mm
Sub-base depth 150mm 150mm 100mm
Base type 40mm tarmac 50mm tarmac 25mm tarmac
Surface product Marshalls Driveline Marshalls Driveline "Concrete blocks"
Drainage 1x linear drain 2x linear drains None included
Manholes Made good Recessed replaced Made good
Guarantee 5 years 10 years 2 years

In this example, Contractor C looks cheapest but has a thinner build-up, vague materials, no drainage and a short guarantee. Contractor B is most expensive but offers the most robust specification.
