Commercial services

Start with how your premises need to work

Building Services London offers commercial building and refurbishment services across London and surrounding M25 areas. If you are improving an existing property, adapting rooms or considering a fit-out, describe how the premises are used and what needs to change.

Business properties involve practical questions beyond appearance. The layout, access, sequence of work and use of the premises may all influence the scope. Mention operating constraints, shared access and any areas that need particular attention in your initial enquiry.

Our service range includes commercial refurbishment and fit-outs, building alterations, structural steelwork, glazing, carpentry, interior finishes and building systems. Specialist fire protection services include fire doors, fire curtains and fire shutters, subject to the requirements of the particular work.

Project information

Explain the site and the business need

Include the property postcode, its current use and a short description of the intended changes. Identify the areas involved and whether the premises will be occupied during work. If there are restrictions on access or working periods, flag them early.

Available plans, schedules or specifications can help describe a larger project. Where these are not available, explain the business problem you want to address. Further information may be needed before a detailed scope can be priced.

Requirements for design, technical assessment, approvals and specialist inspection depend on the proposed work. Establish who is responsible for each item and which services are included in the quotation.

Quotation considerations

Agree the boundaries before work begins

A commercial quotation should make the proposed work understandable. Clarify inclusions, exclusions, material allowances, access arrangements and any decisions still outstanding. Where several services are involved, consider their relationship rather than treating them as unrelated tasks.

Costs and timing are project-specific. We do not publish a generic fit-out price or promise a standard completion period. Share any preferred dates and key constraints so these can form part of the discussion.

BSL offers free quotations and serves East, North, South and West London and surrounding M25 areas. Call 020 3553 2214 to discuss your requirements while the online enquiry provider is being connected.

Planning the work

Turn the business requirements into a clear works brief

Start with what the premises need to do for the business. Describe the people using the space, equipment, storage and customer-facing areas, and explain what currently limits their use. This gives the enquiry a purpose beyond a list of finishes. If the work is intended to support a change in how the premises operate, include that context alongside available drawings or an existing specification.

Separate operational constraints from design preferences. Access routes, business hours, occupied areas and building-management requirements affect the practical discussion, while materials and appearance define another part of the brief. Record both clearly. Where several people can approve changes, identify the decision-making route so the proposed scope is not based on conflicting instructions from different parts of the business.

A commercial enquiry can include a whole fit-out or selected improvements. State which products and services are being supplied separately and which you want included in the proposal. Ask how those interfaces will be managed and what information is needed before pricing. The quotation should distinguish defined work, assumptions and any choices that remain open.

Questions answered

Project FAQs

Can I enquire about selected commercial improvements?

Yes. Describe the specific rooms, installations or surfaces involved and explain the business use. You do not need a complete fit-out brief to discuss an individual improvement. Include any connected work and access constraints so the proposal defines the actual task and its relationship with the rest of the premises.

What should I share for an office refurbishment?

Provide the current layout, intended use, equipment requirements and priorities for the proposed arrangement. Include drawings or specifications where available and identify areas that must remain usable. The fit-out enquiry should distinguish building work, services, furniture and finishes, with responsibilities made clear for each element before the complete scope is agreed.

Can work be discussed with a landlord’s requirements?

Yes. Share relevant requirements, existing approvals or contractor information supplied by the landlord or managing agent. Identify outstanding decisions and who is responsible for them. Those requirements should remain visible alongside the business brief so product choices, installation and connected building work can be considered against the same current information.

How should changes to a commercial scope be recorded?

Ask for the proposed change, reason and implications to be explained before agreement. Keep the current drawing or specification clearly identified, including any effect on separate suppliers or retained areas. A written record helps distinguish the original quotation from later decisions and supports a clearer discussion of pricing, responsibilities and the proposed sequence.

How do I begin a commercial quotation enquiry?

Call or email with the postcode, business use and a short description of the work. Mention occupancy, access constraints and any drawings or specifications already available. If the brief is still developing, explain your main priorities and what needs to work differently. The next information needed can then be established for the actual premises.
