GTM Quest editorial guide · Updated 10 October 2026

Find UK agencies by capability without ranking claims

Practical guide · 01

Use a directory to form a shortlist

A directory record helps you find a supplier; it is not proof of current capacity, pricing or suitability. Read the agency’s current site and put a specific brief to it.

Your decision

Whole motion

You need target selection, positioning, channels and operating ownership joined together. Compare scope and handover.

Specialist discipline

You need a defined creative, media, technical or research capability. Ask for work relevant to that discipline.

Local delivery

You need a particular language, meeting location or market presence. Verify who actually provides it.

Practical guide · 02

Verify the fields that change

Agency services and teams change over time. Treat historic descriptions as a starting point and confirm the facts that affect your buying decision.

  1. 1

    Identity

    Check the company and current website. Confirm the contracting entity and the named delivery lead.

  2. 2

    Capability

    Read original case studies and service descriptions. Do not treat a generic industry label as demonstrated experience.

  3. 3

    Availability

    Ask about capacity, proposed team and start conditions. Record the scope and costs in writing.

Practical guide · 03

Worked example: three suppliers, one brief

Fictional example: a UK team needs better account qualification. It can compare suppliers fairly by giving each the same bounded problem.

  1. Stage 101

    Brief

    Provide the segment, rejected-account examples and the current sales handoff. Remove personal and client-sensitive details.
  2. Stage 202

    Question

    Ask each supplier what it would investigate before choosing channels. Compare reasoning rather than slide count.
  3. Stage 303

    Select

    Choose from relevant evidence, clear ownership and a usable scope. A directory position is not a quality score.

Practical guide · 04

Compare equivalent scopes

Agency categories can conceal different services.

Compare

Same brief

Give suppliers the same commercial problem and constraints.

Different offers

Record exclusions before comparing price.

Practical guide · 05

Inspect the proposed delivery team

The directory describes a firm, not your engagement.

Compare

Named

Ask who works on the account.

Available

Ask about capacity and how work is prioritised.

Practical guide · 06

Read the original case

A headline result needs context.

Compare

Circumstances

Compare segment, period, spend and work performed.

Limits

Keep single-case evidence separate from expected outcomes.

Practical guide · 07

Ask for the ongoing cost list

A programme has costs beyond the supplier fee.

Compare

Supplier

Separate labour and project charges.

Infrastructure

Separate tools, data, media and internal support.

Practical guide · 08

Compare the handover

Your next operator will need the operating history.

Compare

Ownership

Confirm access and asset ownership.

Continuity

Confirm documentation and maintenance responsibility.

03/ how we work

Considering a GTM partner? This is how we work

GTM Quest is a go-to-market consultancy in London.

We define who you sell to and why they should choose you, then build the system that turns it into pipeline: LinkedIn, founder-led content, buying signals and outbound, running on a data layer you own.

We run it with you, or build it and hand it over.

The data, the tooling and the playbooks stay yours.

Every engagement is scoped and quoted in writing after the discovery call.

How much of the work do you want to own?

Handover + support

We hand over, then stay close

Everything in Handover, then a consultant stays on one or two days a week to optimise and troubleshoot.

  • ✓ Everything in Handover
  • ✓ One or two days a week of consultant time
  • ✓ Weekly optimisation calls
  • ✓ Slack and email support

Best for teams building their own capability.
