Frequently Asked Questions

1) Q: Will I need planning permission for my extension or building works?

A: You will need to check this with your local authority Planning Department, and obtain the necessary permission if required. Depending on your local authority, this process can take several weeks or even months.

At TWS Construction we can help you with your application alongside an architect you have appointed.

Note: you may need Building Regulations Approval even if you do not need planning permission. Building Regulations Approval, if required, will be obtained by TWS Construction as part of the building process, however there will be a fee to pay for this.

2) Q: What is the difference between an estimate and a quote?

A: An estimate is an approximate calculation of the likely cost involved in your works, to give you an idea of what you might expect to spend. The figure given in an estimate isn’t binding.

A quote is a more detailed and accurate costing of the works, giving a fixed price. It will detail exactly what is and what isn’t included in the price.

Please note that if any changes are subsequently requested, or there are unforeseen problems discovered during the works, then these will not have been included in the original quote and there will be a revised quote/additional charge.

3) Q: How long is a quote valid for?

A: A quote is valid for 60 days

4) Q: Are all your staff fully trained?

A: All our staff are fully trained, having the appropriate training and certification in the use and operation of the necessary plant & machinery, and also in Health & Safety. Site Supervisors have all completed the Site Supervisors Safety Training Scheme.

5) Q: Is the company Health & safety accredited?

A: Yes, we are accredited to CHAS (Contractors Health and Safety scheme), which is a widely known and recognised health & safety scheme. Under the scheme, an annual assessment is made of our health & safety processes and procedures and accreditation is only renewed if we are still deemed to satisfy the requirements.

6) Q: What happens if there are any changes I want to make to my plans once work has commenced?

A: If you want to make any changes once the work has commenced, we will be happy to discuss the options with you, but this may have an effect on the cost of the works, and also the timescales, as we may not be able to schedule in additional works until a later date.

7) Q: Will there be a single point of contact for me to discuss progress with throughout the works?

A: Yes, the Site Supervisor will be available to you on a daily basis. The managing director, Russell Towers, will also be happy to discuss any issues that you may have that cannot be resolved on site.

8) Q: What happens if I’m not happy with some aspect of the works?

A: We hope this won’t happen as with an accurate quote and an experienced Site Supervisor on site each day, there should be no reason for issues not to be resolved.

However, if you are unhappy with any aspect, please contact our Head Office in Thirsk, and we will attempt to resolve any issues through our Complaints Procedure.

We value our customers and treat them fairly.

9) Q: What are your normal payment terms?

A: This depends on the size of the job, and the resulting cost of the materials, but generally
we ask for a 25% deposit, and the balance on completion. On larger jobs, we may ask for
staged payments to be made at agreed progress points for the works.

Payment is due 14 days after the date of any invoice.

10) Q: What is the average lead time between agreeing to the work and the work actually starting?

A: This varies, depending on how much other work we have planned in our schedule at the time, but on average it will be around 8 weeks (assuming any necessary planning permission is already in place).
