Building Services London
Building, refurbishment and home improvement services for the way you live, across London and surrounding M25 areas.

Residential services
Building Services London offers residential building and improvement services for homeowners across East, North, South and West London and surrounding M25 areas. From extensions and loft conversions to individual rooms and finishing details, the aim of your enquiry is to explain what would make your home work better.
Some projects begin with a clear scope. Others begin with a problem: limited storage, a layout that no longer suits the household, rooms that need updating or outdoor space that could be more useful. You can describe that starting point without having every answer.
Our service range covers building and refurbishment, kitchens and bathrooms, glazing, bedrooms and carpentry, interior finishes, roofing, building systems and outdoor improvements. Explore the relevant categories, then tell us which parts relate to your property.

One property, connected decisions
A kitchen change may affect flooring or electrical work. A new extension may involve glazing, joinery and decoration. Listing related improvements helps you explain the scope you want to discuss.
Explore house extensions →Before you enquire
Provide your property postcode, the rooms or areas involved and a few words about the changes you have in mind. If the home will remain occupied, mention any access or scheduling constraints.
A preferred timescale or budget range can be useful if known. Photographs and drawings are optional for the initial enquiry; further information may be needed to define a quotation.
Separate essential work from ideas you may consider later. Think about which changes affect everyday use and which are primarily about appearance or finish.
Where specialist design, permissions or inspections are needed, establish responsibility for those items before agreeing the work. Product specifications and guarantee terms should also be clear.
Planning the work
Start with the parts of the home that no longer suit the household. Limited storage, an awkward room layout, tired finishes and insufficient living space suggest different types of improvement. Describe the problem and the result you want before committing to a final product list. Photographs, a simple room sketch and examples of preferred finishes can help make those priorities easier to discuss.
Think about the connections between rooms as well as individual changes. New glazing may meet a floor being retained, fitted furniture may affect access to sockets, and a kitchen refurbishment may involve several installations. List those relationships in the enquiry and identify the features you want to preserve. This helps define the wider work without assuming that every related task is automatically included.
If the home will remain occupied, explain the rooms and routes that need to stay usable. Mention shared entrances, delivery access and any household constraints relevant to the proposal. These details help establish practical arrangements for the actual project. Keep preferred timing separate from a confirmed programme until the scope and necessary information have been agreed.
Keep a simple record of products, drawings and decisions as the enquiry develops. Mark which information is current and which is only an example of a preferred style. If you change a room layout or supplied product, ask what that means for related work before agreement so the proposal continues to describe the same intended result.

Yes. Provide a room-by-room list of changes and identify your priorities. Explain which items are essential and which could be considered separately. A structured enquiry helps distinguish individual tasks from shared preparation, access or finishing work, while keeping the scope appropriate to the improvements you actually want.
Describe the appearance and practical result you want, using examples where helpful. Identify choices that are still open and ask which specifications are needed for a useful quotation. Keep product supply and installation responsibilities clear when selections are made so later purchases reflect the agreed scope and room arrangement.
Yes. Identify those items and share available specifications before ordering. Confirm who checks suitability, measurements, delivery and installation requirements. A product purchase and its fitting are separate responsibilities, so the quotation should make clear what is included and how your supplied items connect with preparation and other work.
