About Call Centers providers
Companies providing inbound and outbound phone, chat and email contact center services.
Call center companies handle inbound and outbound customer conversations by phone, chat and email. Agent quality, training and reporting matter more than raw headcount.
In the United Kingdom, Call Center Companies are concentrated around London, Manchester, Birmingham, Edinburgh and Bristol. Local rates sit at the upper end of the global ranges, so many buyers in the United Kingdom pair a local lead with nearshore or offshore delivery to manage cost. For regulated services, always confirm the provider is licensed to operate in the United Kingdom.
How to choose the best Call Center Companies in 2026-2027
- Ask for customer satisfaction scores from current clients.
- Listen to call recordings or mystery-shop them.
- Ask about agent training, attrition and QA scoring.
- Check reporting on handle time, resolution and satisfaction.
What does it cost?
Outsourced call centers commonly charge $8-$15 per agent hour offshore, $25-$65 onshore, or per-minute and per-call pricing for answering services.
Before you sign
Ask for a written proposal with scope, milestones, team members and exit terms, and speak to at least one current client of each shortlisted provider.

How this list is compiled
Worldwide view: Clutch-verified specialists (registered businesses independently verified on Clutch with a working website, ordered by their number of verified client reviews) followed by established industry leaders. Country view: the main list is strictly local. It shows only Clutch-verified firms with an office in the selected country and established firms based in that country that the iCreativez research team selected for their scale and track record. Large international firms and remote teams that serve the country appear in a separate, labelled section and are never counted as local. Where we have not yet verified enough local firms, the page says so instead of padding the list. Minimum project size, hourly rates and team size are as published by each company in November 2026. Inclusion is free and not paid for. Providers can request a review via our contact page.
