Chess Telecom and NBC: Why Former NBC Customers Say Quality Dropped After the Acquisition

The Pattern That Is Hard to Ignore

Scroll through the 1-star reviews on uk.trustpilot.com/review/chesstelecom.com and you will see a specific kind of complaint — one that cannot be explained by ordinary customer churn. It comes from customers who did not originally buy from Chess Telecom. They bought from NBC — a smaller, regional provider that Chess acquired. And the thing these reviewers repeatedly say is: before the acquisition, NBC was truly brilliant. Since Chess took over, the service they receive has materially changed.

This article explains how Chess has grown by acquisition, what the NBC transition has specifically looked like for customers, and what your options are if you are a former NBC customer now uncomfortable with what Chess provides.

How Chess Grew

Chess Telecom (also trading as Chess ICT) has expanded substantially through acquisition. Its growth strategy has involved absorbing smaller UK telecoms and IT providers, integrating their customer bases onto the Chess platform, and cross-selling the wider product mix.

NBC is one of those acquired businesses.

What Reviewers Say About the NBC Transition

From public 1-star reviews on uk.trustpilot.com/review/chesstelecom.com, former NBC customers describe:

Pre-acquisition NBC: Responsive, relationship-driven, technically competent, known staff who answered their own phones.
Post-acquisition Chess experience: Longer wait times, AI bot routing, accounts migrated with errors, services changed without clear communication, contact lists lost during platform migrations.

The specific phrase "truly brilliant" applied to the pre-acquisition NBC service appears in Trustpilot reviews written by customers who stayed when Chess took over.

We are reporting what reviewers publicly say. We are not making direct accusations.

Why Acquisitions Often Create This Pattern

This is not specific to Chess — it is a pattern common across UK business telecoms when large providers acquire smaller ones:

1. Platform Migration

The acquired customer base is usually moved onto the acquirer's billing, provisioning and support platform. Data does not always transfer cleanly. Contact lists, billing references and service configurations can go wrong.

2. Staff Transition

Known account managers at the acquired business are often restructured, reassigned or depart. The relationship that made the original service good breaks.

3. Process Standardisation

Small providers succeed by being flexible. Large providers succeed by being standard. Flexibility that made the acquired business attractive is often the first thing to go.

4. Cross-Selling Pressure

Acquired customers become targets for the acquirer's wider product set — IT services, cyber, managed services. Some of this can land uncomfortably close to "services added without explicit consent" (see Chess Telecom contract problems).

5. Support Automation

Larger providers invest in automated support — portals, chatbots, AI agents. Customers used to reaching a specific human find themselves routed through self-service.

Have Your NBC Terms Changed?

If you were an NBC customer when Chess acquired the business, the first question to answer is: what did you actually agree to, and what are you now signed up for?

Check Your Original NBC Contract

Dig out the signed NBC paperwork. Read the term, the price increase clause, the included services, the notice period.

Check Your Current Chess Bill

Compare line-by-line to what the NBC contract provided for. Differences may be:

New services added (Dark Web Monitoring recurs in reviewer complaints)
Different price per line
Different allowances
Services that were included now charged separately

Check What You Signed with Chess

Any contract signed with Chess after the acquisition takes priority over the NBC paperwork. But if you were simply migrated without signing anything new, the original NBC terms may still apply.

Your Options as a Former NBC Customer

Option 1: Stay and Live With It

If service is acceptable and the price is fair, no action needed.

Option 2: Negotiate with Chess

Raise issues in writing. Ask for the original NBC terms to be honoured, or for service restored to the pre-acquisition standard.

Option 3: Complain Formally

If service has demonstrably dropped below what was agreed, that is a breach of the underlying contract. Formal complaint, then CISAS. See Chess Telecom complaints and CISAS.

Option 4: Leave

If you are at or near the end of your original NBC contract term (or Chess cannot enforce an extension beyond the original term), leave. See leave Chess Telecom.

The Rule That Applies to All Four Options

Keep everything in writing. If Chess calls about your migration complaint, say: "Please put that in writing and email it to me."

Written evidence wins at CISAS. Your recollection of how NBC used to be does not — unless it is backed up by contracts, invoices and emails.

What to Gather if You Are Challenging the Migration

Original NBC contract
All NBC invoices before the acquisition
Any communication from Chess about the migration (letters, emails)
Any contract signed post-acquisition with Chess
Current Chess invoices
Service issue log (dates, durations, impact)
Evidence that specific services changed without consent (invoices showing new line items)

Frequently Asked Questions

Did Chess Telecom acquire NBC?

Yes. Chess has grown through a series of acquisitions of smaller UK telecoms and IT providers, NBC among them. Former NBC customers publicly state on uk.trustpilot.com/review/chesstelecom.com that the service they received before the acquisition was materially better than what they receive now.

Am I still on my original NBC contract terms?

Depends. If you were migrated without signing new paperwork, your original NBC contract terms may still apply until the end of the original term. If you signed a new Chess contract after the acquisition, that governs. Check your files or ask Chess for both sets of paperwork in writing.

What can I do if Chess is not honouring my NBC terms?

Raise it in writing. Ask Chess to restore the original NBC service level or compensate for the change. If unresolved, formal complaint and then CISAS.

Why do Chess acquisitions cause quality drops?

Platform migration, staff restructuring, process standardisation and cross-selling pressure are common issues in telecoms acquisitions. Not specific to Chess — but reviewers say the NBC transition has shown them clearly.

Should I leave Chess if I was an NBC customer?

Depends on your specific situation. If service has degraded and you are near the end of your term, yes. If you are in the middle of a long contract, calculate the ETF against switching savings and consider challenging the contract if service has demonstrably breached.
