How to read a builder’s quote (and why most homeowners struggle with this)

You’ve got three quotes sitting in your inbox. One’s £15,000, one’s £22,000, and one’s £18,500. Which one do you choose?

If you’re like most London homeowners, you’ll be tempted by the lowest number. We get it, renovations are expensive, and saving money matters. But here’s what we’ve learned from managing over 1,500 London renovations: the cheapest quote is rarely the best value.

So how do you actually compare quotes properly? And how do you ensure you’re paying a fair price to the right person? We asked our co-founder, and renovation expert, Thomas, who matches all homeowners to their perfect Pager, to break down what he looks for when reviewing a builder’s quote because at The Page. This is exactly what we do for every single project.

The three things every good quote must have

1. A detailed, itemised scope

This is where most quotes fall apart. You need to see exactly what you’re being charged for- not just a lump sum at the bottom of the page or on a WhatsApp message.

A proper quote should break down costs by task and area. For example:

• How much for tiling the bathroom (including materials, labour, and prep)?
• What’s the cost for electrical work versus plumbing?
• Are they charging separately for materials and labour, or is it bundled?

Why this matters: When everything’s lumped together, you can’t spot what’s missing or what’s been overpriced. And when something inevitably changes during the project, you won’t have a clue what the adjustment should cost.

Red flag: Vague line items like “bathroom works – £8,000” or “kitchen renovation – £15,000” with no further breakdown.

2. An understanding of the level of management you’re paying for

Not all builders operate the same way, and their prices reflect that.

A sole trader working alone will charge less than a small company with a project manager, admin support, and multiple fitters. But are you saving money, or are you trading cost for service?

With a sole trader, you might get:

• Speedy communication (which can be great)
• Lower overhead costs
• But also: you’re their only point of contact when things go wrong, they’re juggling your job with others, and there’s no backup if they’re unwell or overbooked

With a small company charging 15% more, you might get:

• A dedicated project manager
• Better coordination across trades
• Someone to chase suppliers and handle admin
• More accountability

Neither is wrong. It depends on your project, and your tolerance for managing things yourself. 

The problem is most quotes don’t spell this out. That’s where we come in! We help you understand what you’re actually getting for your money. All of our Pagers quote with clear breakdowns, so that you can compare apples for apples. 

3. First fix materials to be included

First fix is everything structural that happens before plastering and decoration: timber frames, joists, cables, pipes, insulation.

A thorough builder will include these costs in their quote. A lazy or inexperienced one will miss them, either because they didn’t properly assess the job, or because they want to keep the initial number low. They might presume that you want a quote without them; if you’re doing some DIY and working with the builder, this might be the case, but for 99% of homeowners it’s not.

Why this matters: If first fix materials aren’t in the quote, you’re either getting an incomplete price (hello, surprise costs halfway through), or you’re working with someone who hasn’t thought through your project properly or communicated as well as they should have.

Red flag: A quote that only lists labour and finishing materials without mentioning structural components.

Why reviewing quotes is actually quite hard

Here’s the thing: reviewing quotes properly is time-consuming and, frankly, intimidating if you’re not familiar with building work.

You’re trying to:

• Compare different pricing structures
• Spot what’s missing without knowing what should be there
• Decode builder jargon
• Work out whether higher prices mean better service or just better sales patter
• Make a decision that could affect your home and budget for months

Most first-time renovators (and even experienced ones who’ve been burned before) find this process overwhelming. Which is exactly why we made it part of our service.

How The Page helps to review quotes with you

We believe in helping homeowners to learn and understand so that they can make decisions confidently, based on knowledge and clarity, not hopes and dreams. We support all homeowners to understand each quote, compare any differences, and understand why some elements have a higher cost attached. No gate-keeping, no lack of control, and no decisions made for you. 

This is why the quote review isn’t an afterthought – it’s built into our process:

1. We brief your Pagers properly so quotes are comparing like-for-like
2. We review every line item with you to spot gaps, inconsistencies, or red flags
3. We help you understand what you’re paying for and whether it’s reasonable
4. We push back on vague pricing so you know exactly where your money’s going
5. We guide you through trade-offs between cost, service level, and timeline

Because here’s what we believe: you shouldn’t need a construction background to get a fair deal on your renovation. Transparency isn’t a nice-to-have, it’s the foundation of how we work.

The bottom line

A good quote tells you more than just the price. It tells you whether the builder has properly assessed your job, how they operate, and whether they’re being honest about what it will take.

Don’t just pick the cheapest number. Pick the quote that gives you confidence you know what you’re signing up for, which might, in fact, be the lowest number!
