Trust should be built into the project
Trovix Group is a London design and build company delivering house extensions, loft conversions, full-home renovations, structural alterations and new build homes across Greater London.

Independent verification
A Master Builder you can verify
Trovix Group is a member of the Federation of Master Builders (FMB), Member No. 170642.
Our work was inspected as part of the FMB membership process, and we have agreed to follow the FMB Code of Conduct.
Our membership can be checked independently on the Federation of Master Builders website.
What membership involves
Vetted membership
FMB membership involves professional checks and an inspection process before a builder is accepted.
Work inspected
Our work was inspected as part of the membership process, with the latest inspection recorded on 29 July 2026.
Professional accountability
Members agree to follow the FMB Code of Conduct, and the FMB provides a dispute-resolution process where applicable.
What trust looks like in practice
Clear accountability
Every project has a dedicated project manager as your single point of contact, with responsibilities agreed before work begins. Trovix Group provides a 10-year structural warranty on new-build homes, house extensions, loft conversions and structural alteration works, subject to the scope and terms set out in the project contract.
Clearer costs
We would rather explain what drives the price than publish an unrealistically low headline figure. Our cost tools give an early indication; a firm quotation follows once design, specification and site conditions are understood. We provide a detailed agreed contract sum based on the defined scope of works. Any client-requested changes, unforeseen conditions or agreed variations are documented and priced before proceeding.

Our credentials are independently checkable rather than self-awarded, so you can confirm who you are dealing with before you commit to anything. Trovix Group maintains appropriate business and construction insurance for the work we undertake, including Public Liability and Employers’ Liability cover. Project-specific insurance requirements are reviewed where applicable.

Certified specialist trades
Regulated work is carried out by appropriately qualified trades — for example competent-person electrical and gas registrations — and the relevant certificates are handed over at completion.
Structural design by qualified engineers

In-house team, specialist trades, one line of responsibility

Who is responsible for the whole job? Trovix. You have one dedicated project manager and one company accountable for the build, whichever specialist trade is on site that week.

Enquiries answered within 24 hours
We aim to respond to new enquiries within 24 hours. Following a site visit, straightforward projects can often be quoted within 24 hours. Where further design, structural review or specification work is required, we confirm the quotation timescale after the visit.
A coordinated professional team
A coordinated professional team. Trovix can work with your existing architect, structural engineer and consultants, or help coordinate the appropriate professionals as part of the project. Either way, we manage the construction process around one clear point of responsibility.
