About Forwell
Family-run construction specialists in Essex
Run day-to-day by two brothers with years of industry experience, Forwell Construction delivers loft conversions, extensions and home improvements with clear communication, reliable timelines and quality workmanship.
After years in the construction industry, we saw how frustrating the process could be for homeowners: unclear quotes, poor communication and projects that became more stressful than they needed to be. So we decided to do things differently.

FAQs
Questions about building work
Can’t see your question? Call us on 020 3488 1988 or send us a message and we’ll be happy to help.
Do I need my own architectural drawings before contacting you?
Not necessarily. We can work from existing plans, but we also offer a design and build service where we partner with trusted architects to take your project from a rough idea to a fully approved technical drawing.
Do you handle planning permission and Building Regulations?
Yes. We can navigate the local council applications for you, making sure all structural work meets current UK Building Regulations and passes every necessary inspection.
How do you provide quotes, and are they fixed?
We provide comprehensive, itemised quotes rather than ballpark estimates. Once the scope of work is agreed and a contract is signed, that price is fixed. Any changes you request during the build are documented with a formal change order, so there are no surprises.
What are your payment terms?
We never ask for the full amount upfront. We typically take a deposit to secure the start date, followed by stage payments tied to completed milestones, such as groundworks finished or the roof watertight. You only pay for work that has actually been done.
Are you insured?
Yes. Forwell Construction carries comprehensive Public Liability and Employers’ Liability insurance, and we are happy to provide copies of our certificates on request.
Do you provide a warranty on your work?
Yes. All our structural work comes with a standard 10-year guarantee, and we provide a 12-month defects liability period for all finishes.
