How much does a boiler repair cost in London?

What does this page tell me about Protocol Group Limited?
The registered company name, registered office address, Companies House number and incorporation date, all taken from the public Companies House register. It does not include reviews, prices, staff details, or confirmation that the company is currently trading.
Can I see reviews for Protocol Group Limited?
Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the engineer for recent local references, and confirm Gas Safe registration before any work starts.
Is a new boiler covered by a warranty?
New boilers typically carry a 5 to 12 year manufacturer warranty. It is conditional on the boiler being registered shortly after installation and serviced every year by a Gas Safe registered engineer, so keep your service records.
