Fixed prices for your Loft Conversion

A Loft Conversion price you can trust.

A loft conversion is one of the most valuable investments you can make in your home. At Charles Grosvenor, we make sure that investment is one you can plan for with complete confidence. We work exclusively on a fixed-price basis, from the moment we quote for your conversion to the day we hand over the completed project.

Most people who come to us have heard at least one horror story – a builder who quoted one price and invoiced another, or a project that ground to a halt over a disputed payment. It’s one of the most common reasons homeowners put off what would otherwise be a straightforward decision.

We made a deliberate choice to work differently.

Our fixed price
commitment to you.

Every Charles Grosvenor quotation is carefully prepared to give you a clear picture of the cost of your loft conversion. Your initial quotation is valid for one month, giving you time to consider your options and decide whether to proceed.

If you accept the quotation and sign your contract within that period, your agreed price is fixed. If you decide to proceed after the one-month quote validity period has expired, we’ll need to review and reissue your quotation, as the cost of materials and other components may have changed.

Once your contract is signed, however, the agreed price is guaranteed. Even if you need to postpone your project for several months, we’ll honour the price set out in your signed contract. You won’t face an increase simply because material costs have risen in the meantime.

Before any work begins, we break down every element of your conversion in full: the conversion type, staircase design, plumbing, plastering, electrical work – right down to the light switches and sockets. There are no provisional or ballpark figures. You always see exactly what you’re paying for, and that figure doesn’t change.

You won’t find any vague clauses buried in our small print. What we quote is what you pay.

Staged payments, on your terms.

We understand a loft conversion is a significant investment, and we can structure your payment schedule to reflect that.

Rather than a large upfront sum, payments are agreed in advance and taken in staged instalments as your project progresses – again, this is written into your contract from the very start so there are no surprises for you later on.

You’ll always know what’s been spent, what’s due next, and when the final balance is due.

We want you to feel in control of your budget throughout the entire build.

Please note: Our fixed-price covers the work detailed in your agreed contract. Once the contract has been signed, any additional work outside the agreed scope will incur an extra charge. In some cases, Building Control may require additional measures, such as a misting system, as a condition of approving your loft conversion plans. Should this happen, the additional work and associated costs will be discussed with you separately.
