Why businesses stay with us

The support is the product.

Getting connected is the easy part. What matters is who picks up when it stops working. Every Synergy Max customer gets unlimited support at no extra cost, from the same people who surveyed the site and installed the kit in the first place.

One team, start to finish

The person who surveys your site is the person you ring six months later. No handovers, no explaining it all again.

Support that costs nothing

Calls, changes, moves, training, fault chasing, all included. You'll never get an invoice for asking a question.

On site, anywhere in the UK

Head office in Merseyside, sites in Aberdeen and Exeter? We travel. Engineers attend wherever your people actually work.

We chase the network, not you

Openreach, the carrier, the ISP. We hold the line, push for updates and tell you what's happening as we hear it.

When the line goes down, you keep working.

Downtime costs more than the circuit ever did. We design connections with a plan B built in, monitor them from our side, and usually know something's wrong before your team does.

  • 4G and 5G failover that switches over automatically
  • Dual circuits on separate carriers for critical sites
  • Proactive monitoring with alerts to us, not just to you
  • Loan handsets and routers while faults are fixed

Recent work

300 Mbps across a riding school with no fibre in sight

A disabled riding school in St Helens needed coverage across stables, outbuildings, paddocks and two manèges. We delivered a 5G router pulling over 300 Mbps, a Cloud Key and five outdoor access points, so staff and volunteers stay connected right across the site.

Where we work

Based in Liverpool. Working across the UK.

Our roots are on Merseyside, but our customers aren't. If your business has sites spread around the country, you get one supplier, one support number and engineers who'll travel, instead of six regional contracts and nobody to blame.

Common questions

The things people ask us first.

Correct. Support is included with every service we provide, phone, email or a visit if it needs one. Training, moves, changes and fault chasing are part of the deal, not an add-on.

Yes. We port your numbers across to the new system, including geographic and non-geographic numbers, and we schedule it so there's no gap in service.

Hosted phones and mobile can usually go live within days. Broadband depends on the line: SOGEA and FTTP are typically a couple of weeks, while leased lines need a survey and a longer lead time. We'll give you a realistic date up front, not a hopeful one.

That's exactly the sort of work we're set up for. One account, one bill if you want it, one number to ring, with engineers attending sites anywhere in the UK.

No. We're independent, with access to the whole telecoms market, so we recommend what suits your building and your budget rather than what one supplier wants us to sell.

Tell us what's not working. We'll take it from there.

Whether it's patchy Wi-Fi, a phone system nobody understands or a broadband provider you can't get hold of, start with a conversation. No commitment, no jargon.
