Our boiler replacement process is designed to ensure safe installation, efficient heating performance, and reliable hot water. All work is carried out by Gas Safe registered engineers, following manufacturer guidelines and UK gas safety regulations.
We review your boiler, heating system, and hot water use to assess your needs and assign a skilled boiler engineer for the job.
The boiler is installed to current gas safety standards, with all connections completed carefully. We set the system up to work correctly with your existing central heating and radiators.
We check pressure, heating performance, hot water output, and system response to confirm safe and reliable operation. Radiators and controls are tested so the boiler works as it should from day one.
Before leaving, we explain how to use the boiler, what to watch for, and when servicing is due. Boiler servicing and maintenance stay available to keep warranties valid and avoid future problems. Our engineers can advise on carbon monoxide safety where needed.

I got charged for 150 pounds for visit and I have been told to pay additional 1000.00 pounds to fix my boiler , because it is German company Viessmann boiler part will cost 350.00 pounds plus labour 650 that makes 1000 pounds That is half of price of new boiler plus installation! It is scam company , do not trust PP , scammers , I will never ever call them again
PP gave me a 12 to 6 pm time slot for my faulty boiler. They arrived at 6.50 pm,nearly one hour late and couldn’t get parts as everywhere was closed. Firstly,I would have expected a courtesy call to advise me they were going to be late. Secondly,They should call to reschedule. I was charged £180 + VAT for a 15 minute visit to say everything’s closed. Won’t be using them again.
Overpriced and questionable upselling, rude customer service that threatened to report me to debt collection because I challenged their assessment, I was thoroughly disappointed and won’t ever be using them again.
Avoid this terrible company at all costs. I have had numerous bad experiences with them. They have literally charged me £500 to change a thermostat that was only replaced a year ago, they didn’t even confirm they were charging that part with me. Just left and said they what they had done. Disgraceful!!! Should be illegal
