Website speed and performance optimisation in Crawley
A Lighthouse score on a developer laptop with fibre broadband is not a measurement of your site — it is a measurement of the laptop. The work here is judged on field data from real visitors on real phones, which is also the data Google actually uses. For Crawley businesses, quoted in GBP from $80, typically live in 4 days.
What website speed and performance optimisation includes for a Crawley business
Fixed scope, agreed in writing before development starts. From $80, typically live in 4 days.
- Field-data baseline from Chrome UX Report where your traffic supports it, plus throttled lab testing where it does not
- Largest Contentful Paint work: the actual LCP element identified, then preloaded, resized and served in a modern format
- Interaction to Next Paint work, which usually means shipping less JavaScript rather than reordering it
- Cumulative Layout Shift eliminated: dimensions on media, reserved space for embeds, metric-matched font fallbacks
- Render path fixed — critical CSS, deferred non-essential script, and third-party tags audited for what they cost
- Image pipeline: AVIF and WebP with correct srcset, and lazy loading applied below the fold only
- Caching and compression configured at the server, including long-lived immutable assets
- A before-and-after report with the numbers and the method, so you can reproduce it rather than trust it
The terms for a British client

Why this matters for United Kingdom specifically
UK local search is the most saturated in the English-speaking world, so a merely competent site does not win the job — the quote form does. Every UK build I ship is specified around the enquiry step first and the homepage second.
Why the Crawley quote lists exclusions as well as inclusions
Every quote I send names what is not included as explicitly as what is. Copywriting from scratch, photography, logo design, ongoing content, paid advertising and third-party licence fees are the usual ones. A quote listing only inclusions is not cheaper — it is the same price with the arguments deferred to later.
This is unpopular at the proposal stage and it is the reason fixed prices hold. Someone comparing three quotes for a Crawley project is usually comparing three different scopes without realising it, and the cheapest one is very often the one that excluded the most while saying the least.
Property, lettings and estate agencies in Crawley
Property sites live or die on search and filtering. A listing grid that cannot be filtered by the three things buyers actually care about — price, bedrooms, area — sends people to the portals, and once they are on a portal you are competing on fee with every other agency in Crawley.
The technical half is feed handling: listings usually arrive from a CRM in a format designed two decades ago, and keeping the site, the portals and the window cards in agreement is where the real work sits. It is worth doing properly, because a property still showing as available after it is let generates the angriest phone calls in the business.
Images shipped at ten times the size they display
A hero photograph exported at 4000 pixels wide and displayed at 400 is the most common single cause of a slow page. The browser downloads all of it and then discards most of it. On a phone over mobile data that is several seconds spent waiting for pixels nobody will ever see.
The fix is generating each image at the sizes actually used, serving AVIF or WebP with a fallback, and setting explicit width and height so the layout does not jump while they load. It is mechanical work with a directly measurable result, which makes it the first thing worth doing on almost any Crawley site.
What I am not claiming about Crawley
- I have no office, postal address or phone number in Crawley
- I cannot meet you in person, and if that is a requirement you should hire locally
- I am not claiming existing clients in Crawley specifically — my live work is listed on the work page and you can check it
- Nothing on this page is a guarantee of search rankings, which no developer can honestly offer
Website speed and performance optimisation in Crawley — common questions
- What hours will you be available to us in Crawley?
- My standard day lands at 05:00–14:00 your time — about 5 hours of genuine overlap with a normal Crawley working day. That is enough for one reliable daily window rather than constant back-and-forth, so Crawley projects run on written updates plus one scheduled call a week.
- How long does a Crawley project actually take?
- Three days for a business site, seven for a store, ten for a custom application. That holds because the process is fixed rather than improvised and because your content exists on day one. What stretches a build is almost never the code — it is waiting for copy, logos and photographs, so those are requested before the clock starts.
- Do you provide ongoing maintenance after launch?
- Thirty days of snag fixes are included after launch at no extra cost — anything that does not work as specified gets fixed. Beyond that there are monthly plans for updates, backups, monitoring and small changes. They are optional and cancellable; a site handed over properly does not require a retainer to keep running.
- Can you fix my existing site rather than rebuild it?
- Often, yes, and it is usually the cheaper answer. Speed problems, a broken mobile layout, a form that silently fails or missing structured data are all fixable on the site you already have. I will tell you which of the two you need after looking, and a rebuild only gets recommended when the fix would cost more than starting again.
- Who owns the website when it is finished?
- You do, completely. The domain is registered in your name, hosting sits in your account, the code lives in a repository you control, and any payment provider account is opened in your business name. Credentials are handed to you as they are created rather than at the end, so you are never locked out of your own site.
- What currency will I be invoiced in?
- GBP. Quotes, milestones and the final invoice are all written in GBP so you are never comparing a converted figure against a local supplier's. Regarding tax: VAT at 20% once you are registered — my invoices are outside the scope of UK VAT and you account for them under the reverse charge.
- What payment methods can my Crawley checkout accept?
- For United Kingdom: Stripe, GoCardless for Direct Debit, and Klarna or Clearpay where basket sizes justify it. The right combination depends on your average basket and your customers, and picking wrong is expensive — the payment method a buyer expects but cannot find is one of the most common reasons a checkout is abandoned at the final step.
