Great Britain Services Group Ltd Reviews 

I paid £300 for an emergency call-out arranged through Plumbing Immediately. The engineer from Ninja Boiler Replacement & Repair Ltd attended for around 30 seconds, said the gas meter was faulty and left. No diagnostic work was done.

The next day my gas supplier confirmed the meter was not faulty and restored heating in seconds with a reset.

When I requested a refund, my calls were hung up and I received hostile messages accusing me of sending a threatening email after I followed Citizens Advice guidance.

I have reported the matter to Trading Standards, as I have now seen other customers describe similar issues with Plumbing Immediately/Great Britain Services Ltd.

We contacted Plumber Immediately for a simple boiler pressure problem. On the phone, they ONLY mentioned a £69 call-out fee — nothing about their shocking £249 per hour labour charge or hidden admin fees.

The engineer from Great Britain Services Group arrived and immediately started dismantling parts without any diagnosis or consent. He insisted the boiler filter was broken, which made no sense for a pressure issue.
When we asked for pricing before he continued, he avoided every question.

Only after he had already begun the work, he sent a contract to my wife and pressurised her to accept it instantly. She was alone and felt intimidated with work already underway, so she felt she had no real choice but to agree.

He kept telling us we could claim everything on insurance — clearly to inflate the job. He replaced a filter that normally costs about £170 but billed us £450 for the part alone. He still refused to explain the total cost until the end. The final invoice was £1,753 for a simple boiler pressure issue. Then he refused to leave our home until payment was made immediately. My wife was scared — we paid purely for safety, as the situation felt threatening.

This company’s behaviour was:
1. Deceptive (hiding true pricing)
2. Pushy and aggressive
3. Forcing immediate contract acceptance under pressure
4. Inflating prices and exploiting insurance
5. Using intimidation to secure payment

This was a coerced and frightening experience, not a professional service. Please avoid this company entirely — their approach feels predatory and unethical.

This company is a SCAM! Beware! Good on the phone when booking but rude when you discussed about complaints.
A third party fronting dodgy tradesmen!
£79 for call out, £120 for diagnostic tests that comes with extortionate verbal quote and plans of replacing parts unnecessarily and mind you, there is also an ADMIN FEE!
Plumber charging £400 per hour!

Adam, a plumber from Great Britain Services Ltd, came to fix our boiler 02/11/2025. He mentioned that the boiler needed proper repairs because the pressure wasn’t working correctly and asked for £450 upfront to purchase parts, which I paid. Later that evening, he sent me an inappropriate photo, which left me very disturbed. He apologised and offered to replace the part for free, but I told him it wasn’t necessary since the boiler was working and asked for a refund instead. He agreed but didn’t return the money by the end of the week. When I followed up, he suggested replacing the entire boiler for an additional £550. I declined and reiterated that I only wanted my refund. After another delay, I told him to complete the original work if he couldn’t refund me. He then claimed that he cannot guarantee the boiler would work if he only changed the parts and insisted on replacing the whole boiler for extra payment. At that point, I told him I no longer wanted his services because I didn’t trust him. Regardless of whether I recover my money, I want to report him so he doesn’t treat others this way.

Do not use this company, £370 per hour, + £69 admin fee.

A set of con artists.

Was quoted £200 per hour plus materials for a leaky pipe. The guy was on site for less than and hour and the bill came in at over £700 AVOID AVOID AVOID.

Do not use this service.
They charge an extremely high hourly rate, and in the end the drainage blockage was not resolved. I initially requested jetting, but the plumber refused and gave various excuses (such as “it will create noise and needs neighbors’ approval”). After about an hour, he only did a temporary fix to make it look like the drain was flowing, then left.

A few hours later, the drainage problem returned to its original state. I ended up paying a high fee for a service that was careless and ineffective.

This company charged exorbitant prices, £400 per hour + £69 call out charge. I have been told by other plumbers that these prices are way too high. It was urgent and the job was done on the same day. Even a weekend call-out would be lower. Beware

Came out straight away with a call out charge . Tells you everything . Charged a fortune for a small problem. Should have taken a hour. 3 1/2,hours . And Charged 10% Admin charge . Stay away from these people.

Thank you to Philip who was really helpful and sorted our flooding drain issue out. We have had been unable to source the source of the issue and have had multiple plumbers coming “fix” the draining situation in our house but only resolved the problem temporarily. But after calling this company and having the plumbers come out to us I can confidently say that our problem has been resolved and that our drains are now running and working properly and we are happy!!!
