You’ve finally decided to pull the trigger on that home improvement project. Whether it’s a sleek new kitchen, a much-needed house extension, or a loft conversion in Bognor Regis to take advantage of those coastal views, the excitement is real. But then comes the paperwork.

When you start looking for a builder in Bognor Regis, you’ll likely receive a handful of documents that look very different from one another. Some might be a single-page email with a total figure at the bottom; others might be a multi-page breakdown that looks like a legal contract.

It’s tempting to just look at the bottom number and pick the cheapest one. We get it, building work is a big investment. However, a cheap price on a vague bit of paper is often the most expensive mistake a homeowner can make. In this guide, I’m going to walk you through exactly what should be in a professional builder’s quote so you can compare apples with apples and avoid those "hidden surprise" costs that ruin the experience.

The Big Difference: Estimate vs. Fixed Quote

Before we dive into the list, we need to clear up a common misunderstanding. In the construction world, the words "estimate" and "quote" are not interchangeable.

The "Best Guess" Estimate
An estimate is essentially an educated guess. A builder might look at your project and say, "Yeah, that looks like it’ll cost about £40,000." It’s a ballpark figure based on past experience but without any deep diving into the specifics of your site. The danger? There is no legal obligation for the builder to stick to that price. If the ground is tougher than they thought or the price of timber goes up, you’re the one who pays the difference.

The "Fixed Project Fee" Quote
A quote is a fixed offer. When we provide a quote at Swanbourne Construction Ltd, we are saying: "We will do exactly this work for exactly this amount of money." Unless you change the scope of the project halfway through, that price is locked in. This gives you financial security and peace of mind, which is why we always advocate for fixed project fees over vague estimates.

1. A Detailed Scope of Work

The most important part of any quote is the "Scope of Work." This is a line-by-line description of exactly what the builder is going to do. If it isn't written down, you should assume it isn't included.

A professional scope of work should cover:

Demolition and Preparation: Are they knocking down a wall? Removing an old bathroom? Who is responsible for protecting your floors and furniture?
The Build Phases: This includes groundworks, brickwork, roofing, and first/second fix electrics and plumbing.
Finishings: Does the quote include plastering, painting, and fitting the skirting boards? Or are they leaving you with bare plaster?

By having a detailed list, you can see if one builder has forgotten something vital: like the lintel needed to hold up your roof: while another has accounted for it.

2. Materials: Quality and Quantity

Materials can vary wildly in price. If a quote just says "Materials – £10,000," you should be asking questions. What kind of bricks? What brand of windows? Are the floor joists premium timber or the cheapest stuff they could find at the local yard?

At Swanbourne Construction Ltd, we believe in transparency. Your quote should specify the quality of materials being used. This is especially important for us here on the coast in Bognor Regis. The salt air can be brutal on certain metals and finishes, so we ensure the materials we quote for are up to the task of surviving the West Sussex weather.

Pro tip: Always check if the quote includes "PC Sums" (Prime Cost Sums). These are allowances for items you haven't picked yet, like tiles or taps. Make sure these allowances are realistic!

3. Labour Costs

This should be a clear breakdown of the manpower required for your project. A renovation isn't just one person with a hammer; it’s a choreographed dance of bricklayers, carpenters, electricians, and plumbers.

A good quote will show that the builder has accounted for all these specialist trades. If the labour cost seems suspiciously low, it might be because the builder is planning to do everything themselves: even the parts they aren't qualified for: or they are planning to use "mates" rather than certified professionals. Always prioritize quality labour; it’s what ensures your home remains standing and safe for years to come.

4. Waste Removal and Skips

Building work is messy. Very messy. You’ll be amazed at how much debris comes out of even a small extension.

Check your quote for waste disposal. Does it include the cost of skips? Who is responsible for loading them? Does it include the permit from the local council if the skip needs to sit on the road in a busy part of Bognor?

Some builders leave "waste removal" out of the quote to make their price look lower, then hit you with a bill for five skips halfway through the job. At Swanbourne, we include waste management as a standard part of our service because we don't think you should be left with a pile of rubble on your driveway.

5. Scaffolding and Site Access

If your project involves anything above the ground floor: like a loft conversion in Arundel or a roof repair: scaffolding is a legal and safety requirement.

Scaffolding is expensive. It involves hire fees, delivery, and professional erection. If your builder hasn't mentioned scaffolding in the quote for your two-storey extension, you need to ask why. It’s a significant cost that should never be an "extra."

6. A Clear Project Timeline

While a quote is primarily about money, a professional one will also include a timeline.

When will the work start?
How long is each phase expected to take?
What is the estimated completion date?

While construction can be affected by the British weather (especially our famous South Coast rain!), having a schedule in writing keeps everyone accountable. It helps you plan your life: whether that's moving out for a few weeks or just knowing when you'll finally have a functioning kitchen again.

7. The VAT Question

This is the big one. 20% is a lot of money to suddenly find at the end of a project.

Some builders quote "ex-VAT" to make their prices look more attractive. If you are a domestic homeowner, you have to pay VAT. A professional, honest quote will always be clear about VAT. At Swanbourne Construction Ltd, we are a VAT-registered company, and we always ensure our quotes clearly state the VAT amount so there are no heart-stopping surprises when the final invoice arrives.

8. Payment Terms and Schedule

You should never, ever pay for a whole project upfront. If a builder asks for 100% of the cash before they’ve picked up a trowel, run a mile.

A professional quote will outline a payment schedule. This usually involves:

A Deposit: To secure the start date and order initial materials (usually around 10-25%).
Stage Payments: Payments made at specific milestones (e.g., when the foundations are poured, when the roof is on, when the first fix is complete).
Final Retention: A small percentage held back until the work is finished and you are 100% happy.

This system is fair for everyone. It gives the builder the cash flow they need to buy materials and pay trades, and it gives you the security that you are only paying for work that has actually been done.

Why Swanbourne Construction Ltd Does Things Differently

We’ve seen too many homeowners in Bognor Regis and Chichester get burned by "back-of-an-envelope" quotes. That’s why we’ve built our reputation on transparency and fixed quotes.

When we sit down to price your project, we don't just guess. We look at the structural drawings, we assess the site access, we talk to our trusted suppliers, and we build a comprehensive document that covers everything from the first skip to the final coat of paint.

We want you to feel confident. We want you to look at our previous projects and know that the quality you see there is backed up by a professional business process.

Final Checklist for Bognor Regis Homeowners:

Before you sign on the dotted line, ask yourself these three questions:

Is this a fixed quote or just an estimate?
Does it include everything (VAT, waste, scaffolding)?
Do I trust this builder to be in my home for the next three months?

If the answer to any of those is "I'm not sure," it's time to keep looking. You deserve a builder who respects your budget as much as you do.
