How to Choose a Renovation Contractor in SW and West London

A decision checklist covering evidence, quote detail, payment terms, planning assumptions, programme and project communication.

A strong contractor decision is based on comparable evidence and a clear written scope. A polished gallery helps, but it does not explain what was included, who managed the work or how changes were handled.

Start with relevant project evidence

Ask for completed work that matches the type and scale of your project. A loft contractor should be able to discuss the staircase, fire strategy and roof structure. An extension contractor should explain drainage, temporary works, access and glazing. A flat refurbishment also needs freeholder, managing-agent, noise and common-area planning.

Bluebird's published case studies include:

Use the stated scope, size and programme to decide whether each is genuinely comparable with your property.

Check the quote, not just the total

A useful quote names the drawings and specification used for pricing. It separates structure, services, finishes and external work, and it states what is excluded. VAT should be consistent throughout. Professional fees, planning and building-control fees, surveys and client-supplied items should be visible rather than assumed.

Provisional sums can be necessary where a product or hidden condition is unresolved, but they should be identified and realistic. Ask how any difference will be approved.

Understand the payment schedule

The schedule should follow progress and completed work. Check whether a deposit is required, how often valuations or invoices are issued and what evidence supports payment. Bluebird's stated approach is no deposit upfront and weekly payments for completed work.

Test the planning assumptions

A contractor should not promise that planning permission is unnecessary from a postcode alone. Houses, flats and maisonettes have different rights. Conservation areas, Article 4 directions, listed buildings, freeholder rules and earlier additions can all affect the route.

Use the relevant local guide and its council link:

Ask how the project will be managed

Find out who will be your day-to-day contact, how often the programme is updated and where decisions are recorded. Ask how the team protects occupied areas, manages deliveries and waste, and communicates with neighbours.

A realistic programme identifies design, approval and procurement work before construction. Long-lead glazing, joinery, stone, kitchens and sanitaryware need decisions early enough to avoid delays.

Verify trust signals

Memberships and reviews help only when they are genuine and attributable. Check the contractor's current Federation of Master Builders entry and read reviews on their original platform. Ask whether photographs and testimonials relate to the same completed project being discussed.

A practical final comparison

Before appointing anyone, put the final proposals side by side and answer:

Are they pricing the same drawings and finish level?
Is VAT treated consistently?
Are approvals and professional fees clearly allocated?
Are the programme and payment terms written down?
Are exclusions and provisional sums easy to find?
Is there relevant completed work with a client review?
Is the person selling the job also accountable during delivery?

The best next step is a site-specific conversation. Use the cost calculator for an early guide, review the full project portfolio, then request an itemised proposal.
