Website performance optimisation
Find what is slow.
Fix it.
Prove it.
A complete website performance audit, targeted improvements and a clear before-and-after report. Performance optimisation starts from £495, with a fixed quotation provided after an initial review of the website.
Performance work is not about chasing a perfect score at the expense of your website. The aim is to make the site faster for visitors and administrators while preserving its design, functionality and commercial requirements.
What may be slowing your website down
Website performance problems rarely have one simple cause. We investigate the website, hosting environment and third-party services to identify where delays are coming from.
Poor Core Web Vitals
Oversized or inefficient images
Missing or poorly configured caching
Database bloat and unnecessary stored data
Resource-heavy plugins or themes
Slow WooCommerce product, basket or checkout pages
A slow WordPress administration area
Hosting or server limitations
Heavy page builders and third-party scripts
Poor performance on mobile devices
A complete investigation, followed by targeted improvements
We begin by identifying the causes of poor performance. The work then focuses on improvements that are appropriate for the website, hosting environment and agreed scope.
Comprehensive Performance Audit
We examine page speed, Core Web Vitals, hosting, plugins, themes, database behaviour and front-end assets to identify the main performance bottlenecks.
Core Web Vitals Improvements
Targeted work on LCP, INP and CLS where the website structure and third-party services allow meaningful improvement.
Advanced Caching Configuration
Page, browser, object and server-level caching is implemented or refined to suit the website and hosting environment.
Image Optimisation
Images are compressed, resized and delivered more efficiently without visibly reducing their quality.
Database Optimisation and Cleanup
Revisions, expired transients, database overhead and unnecessary stored data are safely reduced where appropriate.
Plugin and Theme Performance Review
We identify resource-heavy plugins, theme behaviour and third-party scripts that may be contributing to slower pages.
Hosting and Infrastructure Recommendations
We assess whether the hosting environment is limiting performance and recommend changes only where they are justified.
Before-and-After Performance Report
You receive a comparison of relevant measurements, a summary of the work completed, any remaining constraints and recommended next steps.
Clear expectations from the beginning
Performance optimisation can improve technical bottlenecks within the website, hosting environment and agreed scope. It cannot guarantee a specific PageSpeed score, search ranking or conversion rate when required functionality, third-party advertising, analytics, embedded services or hosting limitations continue to affect performance.
Any proposed change that could materially affect the design, functionality or customer experience will be discussed with you before it is implemented.
Typical performance optimisation costs
The cost depends on the size of the website, its functionality and the extent of the performance problems. After an initial review, we will confirm which range applies and provide a fixed quotation before work begins.
Every project includes a performance audit, targeted optimisation, testing and a before-and-after report. The price reflects the amount of investigation and implementation required.
Typical range
Standard websites
£495–£695
For brochure websites, smaller business sites and straightforward WordPress installations with limited integrations.
Typical range
Complex websites
£795–£995
For larger WordPress websites with more plugins, custom functionality, third-party integrations or persistent performance problems.
Typical range
Ecommerce and business-critical sites
From £1,195
For WooCommerce, membership, booking and high-traffic websites requiring more extensive investigation, testing and validation.
Send us the website address and tell us where the slowness is most noticeable. We will review the likely complexity and confirm the appropriate fixed price.
How website performance optimisation works
From the initial review to the final report, you will know what is being investigated, what work has been agreed and what the results show.
Send us the website details
Tell us where the slowness is most noticeable and whether particular pages, devices or administrative tasks are causing problems.
We review the likely complexity
We carry out an initial assessment, confirm the appropriate scope and fixed quotation, and explain what access will be required.
We audit and improve the website
We investigate the causes, complete the agreed optimisation work and test that important functionality continues to work correctly.
You receive the results
You receive a before-and-after report explaining what was changed, what improved, any remaining constraints and the recommended next steps.
Frequently asked questions
Questions about performance optimisation
Answers to common questions about the scope, expected results, access requirements and timescale for performance work.
Website performance can affect search visibility and user experience, particularly where poor Core Web Vitals or very slow pages are creating problems. However, performance optimisation alone cannot guarantee an improvement in rankings because search results are influenced by many technical, content and competitive factors.
No. PageSpeed scores are affected by the website’s design, functionality, hosting and third-party services such as analytics, advertising, embedded tools and payment integrations.
We will improve the areas within the agreed scope and explain any remaining constraints in the final report.
The aim is to improve performance while preserving the website’s design, functionality and commercial requirements.
Any proposed change that could materially affect how the website looks or works will be discussed with you before it is implemented.
Yes. We can investigate slow product, basket, checkout and administration pages, along with database behaviour, plugins, integrations, hosting and other factors affecting WooCommerce performance.
Ecommerce websites usually fall within the business-critical pricing range because they require more extensive testing and validation.
Only where there is a clear reason to recommend doing so.
We may identify plugins that are adding significant overhead, duplicating functionality or contributing to performance problems. Any removal or replacement that could affect the website will be discussed and agreed before changes are made.
We will normally require administrator access to WordPress and may also need access to the hosting account, server controls, caching services, content delivery network or staging environment.
We will confirm the exact access required after the initial review. Passwords should not be sent through the enquiry form.
We will explain where the hosting environment is limiting performance and provide practical recommendations.
We do not recommend changing hosting unless there is a clear technical reason. Any migration or hosting change would be quoted separately unless it is specifically included within the agreed scope.
The timescale depends on the size and complexity of the website and the extent of the problems identified.
Straightforward websites may be completed within several working days. Larger ecommerce, membership or highly integrated websites may require a longer investigation and testing period. We will confirm the expected timescale before work begins.
