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 ! Refused to pay scam beg called different company Mason plumbers UK and paid 250.00 fixed charge , no new parts were needed ! It is scam company , do not trust Pimlico plumbers , scammers , I will never ever call them again
Pimlico plumbers 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 have called me to reschedule. I was charged £180 plus VAT on top for an engineer to visit for 15 minutes to tell me everything’s closed. Won’t be using them again.Very poor
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

We provide central heating services across London, including repairs, servicing, and central heating installations for residential and commercial properties.
Most boiler installations are completed within one day, although larger systems or installations that require pipework upgrades may take longer. Our engineers will assess your heating system and confirm the expected installation time before work begins.
The best boiler depends on factors such as property size, number of bathrooms, heating demand, and available space. Combi boilers are often suitable for smaller homes, while system boilers or conventional boilers may be better for properties with higher hot water demand.
Yes. In the UK, all gas boiler installations must be carried out by a Gas Safe registered engineer to ensure the work complies with gas safety regulations and manufacturer requirements.
A system boiler works with a hot water cylinder and suits properties with more than one bathroom that need a stable hot water supply.
Yes. We install boilers as part of complete central heating systems, including heating and hot water integration.
Boiler replacement is recommended when the existing boiler becomes unreliable, inefficient, or expensive to repair. Older boilers may also use more energy, which can increase heating costs compared to modern high-efficiency models.
