Boiler installation · Hammersmith W6
Make the replacement count.
Vaillant & Viessmann Registered InstallersExtended manufacturer cover included on qualifying installations.
A new boiler should do more than replace an ageing appliance. It should meet your household’s hot-water needs, work properly with the heating already installed and remain accessible long after the cupboard doors are closed.
PEP provides boiler installation in Hammersmith W6, including replacements, relocations and changes from older heating arrangements. We specify the appliance alongside the pipework, controls and system preparation it needs.
From a flat near Hammersmith Grove to a family house around Ravenscourt Park, the starting point is the same: understand the property before recommending the equipment.

Manufacturer-registered installation · Hammersmith W6
Longer manufacturer protection.
No extra warranty charge.
PEP is a Vaillant Advance Installer and a Viessmann Trained Installer. With a qualifying boiler installation, we include the extended manufacturer guarantee or warranty specified in your quotation at no additional cost. We select the right package for your home and take care of registration.
Up to 10 years’ manufacturer guarantee
Available on eligible Vaillant boilers with the required protection package and registration. We confirm the exact term and any qualifying accessories before you accept the quotation.
Agreed extended cover included — no additional warranty fee.
Up to 12 years’ manufacturer warranty
Available on eligible Vitodens models and qualifying installation packages. Other appliances may carry a different term; your quotation confirms the specific cover included.
Agreed extended cover included — no additional warranty fee.
The maximum term is not available on every model. Eligibility depends on the appliance, required accessories, the manufacturer scheme in force and timely registration. Manufacturer terms and annual servicing requirements apply. Annual servicing is a separate service, not included in the manufacturer guarantee or warranty.
Start with the brief
Sometimes the brief is straightforward: replace an unreliable boiler without reorganising the home. In other cases, a refurbishment has exposed a bigger question. Should the cylinder stay? Can the boiler move? Will the current arrangement support another bathroom?
Establishing that brief early avoids choosing an appliance that fits the old installation but not your future plans.
Retaining the location can reduce alterations, but a similar-looking boiler is not necessarily a direct fit. Connections, flue compatibility, cupboard dimensions and maintenance clearances still need checking.
We also review existing symptoms. Uneven heating or repeated pressure loss may originate elsewhere in the system; replacing the boiler alone will not necessarily resolve them.
Moving the boiler can free kitchen space or improve access. The proposed position must also accommodate the flue, condensate drainage, gas supply and heating connections.
We establish these routes before cabinetry, ceilings or new finishes make them difficult to change.
Replacing a conventional arrangement with a combi changes how the home receives hot water. Keeping stored hot water while modernising the boiler is a different project again.
We explain what would be removed, retained or altered, rather than treating conversion as an automatic upgrade. Our conventional-to-combi conversion guide explores that decision in detail.
The building matters
The installation needs to suit the building as well as the household.
In a converted property around Hammersmith Grove or Brook Green, a boiler may sit within a compact kitchen while its flue and services pass through less accessible parts of the building. Identifying private pipework, shared areas and access requirements is an important part of the survey.
For a house around Brackenbury Village or Ravenscourt Park, the question may be how an older heating circuit should serve a changed layout. An extended kitchen, additional bathroom or new underfloor-heating zone can alter the specification.
A refurbishment near St Peter’s Square may also require particular attention to retained features and external alterations. Planning permission is not normally required for wholly internal boiler work, but listed-building status and proposed flue changes can introduce additional considerations. Relevant permissions must be established for the actual property. Planning Portal guidance.
Where the work forms part of a larger renovation, our plumbing installation service in Hammersmith allows the boiler, water services and bathroom or kitchen connections to be planned together.
Different homes. Different demands.
The smallest appliance is not always the best use of space. The highest output is not automatically the best specification.
We consider room-heating requirements separately from hot-water demand, alongside the existing installation and the changes you expect to make.
Where the household regularly uses several outlets together, a suitable cylinder can provide useful stored capacity.
Selection involves more than cylinder size. Recovery performance, controls, available space and the water-supply arrangement all matter. A serviceable cylinder does not automatically need replacing when the boiler changes.
If you are considering a different hot-water arrangement, our vented-to-unvented conversion guide explains the wider considerations.
A combi heats domestic hot water as it is needed, avoiding a separate storage cylinder. It can suit a flat or smaller house where demand and the incoming water supply support that arrangement.
The important questions are practical: how many outlets will run together, what flow is available and what temperature rise must the appliance deliver?
A larger combi may heat a greater volume of water, but it cannot create an adequate incoming supply where one is missing. Manufacturer sizing guidance also distinguishes hot-water output from the heat needed by the rooms. Vaillant’s sizing guidance.
Retaining a compatible heat-only arrangement can be a sensible option when it already serves the home well.
We assess the associated equipment and its condition before recommending retention or conversion. Removing tanks and changing operating pressures should follow a considered design, not simply a preference for newer terminology.
The complete job, clearly defined
A useful quotation should allow you to understand the complete job, not just recognise the boiler model.
Our assessment establishes:
The written scope identifies necessary alterations and separates them from work that is not included. This matters particularly when installation involves a new location, a cylinder conversion or coordination with other trades.
Included with PEP boiler replacements
PEP includes a full-system PowerFlush with its boiler replacements, together with appropriate system protection, inhibitor and water-condition checks.
Cleaning helps remove accumulated contamination from the circuit before it continues operating with the new appliance. It is part of our replacement package, not an optional extra hidden behind a low appliance-only price.
The circuit is assessed first. Deteriorated components, inaccessible sections or shared-system boundaries can affect how the work is approached; any limitations are discussed before proceeding.
A PowerFlush does not repair a failed valve or correct an unsuitable pipework arrangement. Those issues need to be identified separately.
Read about our PowerFlush service in London.
A coordinated heating system
As Vaillant and Viessmann registered installers, we specify the boiler, compatible controls and qualifying manufacturer protection together. We recommend an appropriate current model rather than applying one default specification to every Hammersmith property.
Controls form part of that decision.
A thermostat may be able to switch a boiler on and off without providing the same integration as a compatible modulating control. The intended communication, available functions and retained equipment should therefore be checked before purchase.
Where radiators, underfloor heating and stored hot water share a boiler, their demands also need coordinating. An app cannot compensate for an incorrectly arranged heating circuit.
Our guide to smart heating controls explains the options. For more extensive projects, see our central heating and plant-room installation service.
The qualifying manufacturer guarantee or warranty agreed for your Vaillant or Viessmann installation is included in your PEP quotation, with no additional warranty charge. We handle registration and explain the servicing conditions at handover.

Compare the complete scope
The most useful starting point is the work involved, not a price attached to a photograph of a boiler.
A replacement retaining the existing position and broad arrangement is different from moving an appliance, changing the hot-water system or opening finished areas to alter pipework.
The main cost factors include:
PEP provides a written quotation following assessment. It should be clear what is included, what is excluded and whether a proposed change would affect the price.
When comparing quotations, compare the whole installation: preparation, accessories, controls, testing, registration and agreed finishing work—not only the appliance.
Four stages. One agreed plan.
Send your postcode, boiler details and photographs of the surrounding space. Tell us about any cylinder, proposed renovation or change in hot-water use.
This helps identify the likely scope before the site assessment.
We check the installation requirements and agree the specification, access arrangements and programme. If another contractor is building a cupboard or finishing the room, relevant dimensions and service access should be coordinated beforehand.
Working areas are protected and the agreed removal, preparation and installation work is carried out.
We explain the expected interruption to heating and hot water so you can plan around it. Conversions and relocations can require a different programme from a straightforward replacement.
Commissioning includes the checks required for the selected appliance and installation, with results recorded rather than relying on the boiler simply turning on.
We explain the controls and provide the relevant handover information. Commissioning records, Building Regulations notification and manufacturer registration are distinct parts of the process. PEP arranges the applicable notification and registration for its installation work. Gas Safe guidance on notification.
Explore our heating work
PEP’s heating work includes installations where boilers, hot-water storage, distribution and controls must operate together.
You can see examples in our heating and hot-water project gallery. That wider experience informs smaller replacements too: knowing how the system works helps establish what needs changing and what can sensibly stay.
You do not need a complete refurbishment to work with us. We also undertake defined boiler replacements in flats and smaller houses.
W6 and neighbouring addresses
We cover Hammersmith Broadway, King Street, Hammersmith Grove, Brackenbury Village, Dalling Road, Ravenscourt Park, St Peter’s Square and Hammersmith’s riverside neighbourhoods.
Enquiries are welcome from addresses across W6 0, W6 7, W6 8 and W6 9, together with nearby Brook Green, Barons Court, West Kensington and the Stamford Brook boundary.
Neighbourhood names and postcode boundaries do not always align. Send the full address so we can confirm coverage and understand the building.

Before you book
Yes. PEP is a Vaillant Advance Installer and a Viessmann Trained Installer. We install both brands in Hammersmith W6 and arrange the manufacturer registration for the qualifying package agreed in your quotation.
No. The extended manufacturer cover specified for a qualifying PEP Vaillant or Viessmann installation is included at no additional cost. Eligible packages can provide up to 10 years with Vaillant or up to 12 years with Viessmann. The exact term depends on the model, accessories and applicable scheme; it is confirmed before installation. Manufacturer conditions and annual servicing requirements apply. Annual servicing is charged separately.
Possibly. We check dimensions, manufacturer clearances, connections and maintenance access. Retaining the cupboard should not make future servicing impractical.
Not automatically. Existing radiators and pipework are assessed for condition, suitability and performance. Necessary repairs or changes are identified in the scope.
Yes, where the flat has an individual boiler and the proposed work is suitable. Any relevant freeholder, managing-agent or shared-area requirements need resolving before work begins.
It can be, but bathroom count alone does not decide suitability. Simultaneous use, incoming supply and the appliance’s hot-water capability matter. Some households benefit from retaining stored hot water.
It is included in PEP’s boiler replacement package. The survey establishes the circuit’s condition and identifies any separate repairs or limitations affecting the work.
That depends on the installation. We explain the expected interruption before booking. Relocations, conversions and substantial pipework changes generally involve more work than a replacement in the same position.
Not necessarily. Controls, circulation problems, valves or contamination can produce similar symptoms. The cause should be established before committing to a replacement.
An HIU connected to communal heating is not an individual gas boiler. Check the arrangement with your building manager and let us know when enquiring; it requires a different assessment.
Relevant commissioning information, operating guidance and confirmation of the applicable notification and manufacturer-registration arrangements. We also explain servicing requirements attached to the selected manufacturer protection.
Make a considered start
Whether you are replacing a failing appliance, reclaiming cupboard space or planning heating around a refurbishment, start with the home and the outcome you want.
Send your Hammersmith postcode, current boiler model and a few photographs, together with any plans affecting bathrooms, heating or the boiler’s position. There is no need to remove covers or disturb the installation.
We will help establish the appropriate next step and prepare a clearly defined quotation.
