Vaillant Advance Installer
Eligible Vaillant installations can receive up to 10 years of manufacturer cover. We check the proposed appliance and required protection equipment before confirming the available term in your quotation.

BOILER INSTALLATION · MAIDA VALE W9
PEP installs replacement boilers for flats and houses in Maida Vale W9. Your installation brings together the right appliance, a full PowerFlush and careful commissioning, with extended manufacturer cover included on qualifying Vaillant and Viessmann installations.
¹ Earliest slots depend on the survey, available boilers and our diary. †Cover varies by appliance and qualifying package; registration and manufacturer conditions apply.
Choosing an installer also means choosing who will specify the equipment, complete the checks and arrange registration. PEP combines Gas Safe registration with manufacturer training for the boilers we install.
Eligible Vaillant installations can receive up to 10 years of manufacturer cover. We check the proposed appliance and required protection equipment before confirming the available term in your quotation.
Our Viessmann training informs the installation of your chosen appliance. Depending on the model and registration package, cover may last 7, 10 or up to 12 years; your quote identifies the option provided.

Pure Energy Project Ltd is a Gas Safe registered business. A registered engineer undertakes the gas work, with installation checks and the relevant paperwork forming part of the handover.

SYSTEM CLEANING INCLUDED
A replacement boiler still relies on the pipework and radiators around it. PEP includes full-system PowerFlush cleaning to remove circulating sludge and debris from the private heating circuit before final commissioning.
We work through the radiators, add inhibitor and check the water condition. Suitable magnetic protection is included in the installation scope. In a Maida Vale flat, the cleaning plan follows the confirmed boundaries of that home's system; it does not assume access to communal plant.

THE APPLIANCE AND THE BUILDING
A mansion flat near Elgin Avenue may have a boiler fitted into a kitchen cupboard. A converted home around Warrington Crescent may retain a separate hot-water cylinder. We assess the actual arrangement, available space and household demand before recommending what should change.
For apartments, we establish which equipment serves the individual home and identify any dependency on shared services. Access arrangements and involvement from building management are discussed before the scope is agreed.
We review the current boiler, heating requirements and hot-water use, then explain the replacement options suitable for the property.
The assessment covers the cupboard or utility space, servicing clearances, flue route and accessible connections, including any proposed relocation.
Full PowerFlush cleaning, inhibitor, suitable magnetic protection and water checks prepare the retained heating circuit for the new appliance.
We review existing controls, radiators and any cylinder. Serviceable equipment can stay where its condition and compatibility support the proposed installation.
The agreed appliance and associated connections are installed, followed by commissioning and checks of the heating and hot-water operation.
We complete the commissioning record, arrange applicable notification and manufacturer registration, and explain the controls and documents you receive.
Keeping a compatible boiler in its current position involves a different scope from moving it, altering the flue or changing the hot-water arrangement. Access, pipe alterations, controls and any cylinder work also affect the quotation.
We list the proposed equipment and included preparation so you can compare complete installations. Optional improvements are distinguished from work needed for the replacement.
SPACE, STORAGE AND DAILY DEMAND
Incoming water flow, storage space and demand at busy times all matter. We consider how your household uses its bathrooms and kitchen before selecting the boiler arrangement.
A combi heats water as it is needed, without a separate hot-water cylinder. It can suit a home with limited storage space, provided the mains supply and expected simultaneous use are suitable.
A system boiler heats a hot-water cylinder. For a household using several bathrooms, we consider stored capacity, reheating performance and the available water supply together.
Some homes retain a regular boiler, hot-water cylinder and feed-and-expansion cistern. We assess whether keeping this arrangement or changing system type makes practical sense.

BEFORE WE HAND OVER
Before handover, we record the commissioning results and check how the heating and hot-water controls operate. You receive a practical explanation of the settings, the relevant documents and the servicing requirements attached to your boiler cover.
Share your postcode, boiler model and photographs of its location. Tell us about any problems you would like the replacement to resolve.
Following assessment, we explain the recommended equipment, work involved and manufacturer cover. The quotation records what is included.
We agree access and the expected interruption, prepare the heating circuit and carry out the installation in the agreed sequence.
After the final checks, we demonstrate operation, provide the installation information and explain the registration and servicing arrangements.
7–12 YEARS ON QUALIFYING PACKAGES
Extended manufacturer cover forms part of PEP's quoted package for qualifying installations. Before you book, we identify the appliance, the agreed protection period and anything required to activate it. You know which cover is being provided alongside your new boiler.
The manufacturer's conditions apply, including correct registration and required servicing. Annual servicing is not included in the boiler guarantee, and cover does not automatically extend to radiators, controls or other heating-system components.
PLANNING A REPLACEMENT
Installation appointments can sometimes be available from 48 hours after an enquiry. Timing depends on the survey, appliance availability and engineer bookings. Send us the starting details and we will discuss the earliest suitable date for your property.
Check installation availabilityPRACTICAL QUESTIONS
The appliance is one part of the price. Its location, flue, connections and the equipment being retained determine the work around it. We assess these points before quoting and identify any optional alterations separately.
Yes, where the home has its own boiler and an agreed private scope. We establish how the installation connects with the building before planning access or isolations. If heating comes from communal plant, that requires a separate discussion with the responsible building operator.
Bathroom count alone is not enough to choose. We consider the incoming water supply and which outlets are likely to run together. A cylinder-based arrangement may suit higher simultaneous demand, while a combi can work where supply and usage allow.
Often this can be considered, but the replacement must suit the space, required clearances, flue arrangement and access for future servicing. Photographs help us start the discussion; the survey confirms whether the enclosure or connections need alteration.
Yes. The replacement package includes full PowerFlush cleaning, inhibitor, suitable magnetic protection and checks of the system water. For a flat, we confirm the extent of its private heating circuit before arranging the work.
A straightforward exchange may be completed within a working day. Relocation, conversion or additional pipework can extend the programme. We explain the expected shutdown before booking and coordinate access to keep the agreed work moving.
Keep the registration confirmation and installation record, and arrange servicing as required by the manufacturer. The appliance and installation must meet the conditions for the agreed term. We explain these requirements when handing over your documents.
Send your Maida Vale postcode, the current boiler details and a few photographs of the installation. Whether you are replacing an unreliable appliance or planning a refurbishment, we can help define the work and prepare a clear quotation.
