What we do.
Done properly.

Hilltop focuses on extensions, loft conversions, full refurbishments and kitchens and bathrooms — the projects that demand the most from a builder. We don't take on everything. We take on the right things and do them to a standard that holds up.

🏠

Home Extensions

Single storey, double storey, side returns and wraparound. We handle the planning application, structural drawings, building regulations and every trade on site. You tell us what you want — we deliver it, on time, at the agreed price.

Loft Conversions

Dormer, hip-to-gable, mansard and Velux conversions. The most common way to add significant value to a Surrey home without moving. We manage everything from drawing up the plans to the final inspection.

Full Refurbishments

Whole-house refurbs from strip-out to final decoration. One project manager, one fixed price, every trade employed directly by us. The homeowner's job is to make decisions — not manage a schedule.

02

Fixed-Price Quote

A detailed, itemised quote with a fixed price. No hourly rates. No provisional sums. You know exactly what you're paying before work starts.

03

Planning & Prep

Handover

Full snagging completed before we consider a job finished. Building control sign-off secured. Keys back to you, job done — and we're still a call away if anything needs attention.

There are 23 builders
within five miles.

We know — because our customers have had quotes from most of them. Here's what makes Hilltop the one they come back to.

🏗️

Our own team. Every day.

No subcontractors booked in and then cancelled. Our builders are directly employed — every trade, on site, accountable to us. That's what consistency looks like.

📋

You don't manage a thing

Most builders hand you a list of things to organise. We don't. Planning, building control, structural drawings, material orders — all handled. Your job is to make decisions, not chase trades.

📍

Rooted in Surrey

Whyteleafe-based for over 20 years. We know local planning officers, trusted suppliers and the specific challenges of building in this area — knowledge you don't get from a national firm.

💷

Not the cheapest. Deliberately.

Builders who win on price usually cut somewhere — materials, management, time on site. Hilltop doesn't compete on day rate. We compete on outcome. The projects in this portfolio speak for themselves.

We'd had three quotes before calling Hilltop. They were the only ones who gave us a proper fixed price and actually turned up every day. The extension was finished bang on schedule.

The part where
our clients do the talking.

★★★★★
From the first visit to the day they handed back the keys, everything was handled. No chasing, no nasty surprises. The extension looks incredible and it was done exactly on time.
★★★★★
We'd been let down by a builder before so we were nervous. Hilltop were completely different — professional, tidy, on time. Our loft is exactly what we asked for and the finish is outstanding.
★★★★★
Jon and the team managed absolutely everything — planning, structural engineer, building control. I barely had to do anything. Worth every penny for the peace of mind alone.
