How Much Does a Birthday Cake Cost in London? 2026 Price Guide

If you're planning a birthday celebration in London, one of the first questions you may have is: how much should I expect to pay for a birthday cake?

The answer depends on the size of the cake, number of guests, flavour, decoration and whether you choose a ready-to-order celebration cake or a completely bespoke design.

At Prestige Patisserie, we create handcrafted birthday and celebration cakes from our North London patisserie, with our classic celebration cakes currently starting from £75.

Typical Birthday Cake Prices in London

Birthday cake prices in London can vary considerably depending on what you're looking for.

As a general guide:

Classic celebration cakes: from around £75
Larger or more highly decorated cakes: typically £100–£250+
Bespoke and themed cakes: individually quoted depending on the design, size and complexity
Luxury multi-tier or highly detailed cakes: can cost several hundred pounds

Rather than choosing a cake based only on its diameter, it's useful to start with the number of guests you need to serve. This makes it much easier to compare options and avoid ordering a cake that is unnecessarily large or too small for your celebration.

What Affects the Price of a Birthday Cake?

Several factors determine the final price of a handmade celebration cake.

Size and Number of Guests

Naturally, a cake for 30 or 40 guests requires considerably more ingredients and preparation than one designed for a small family celebration.

At Prestige Patisserie, our online cakes are organised by the approximate number of guests they serve, making it easier to select the appropriate size.

Flavour

The ingredients and preparation involved can vary considerably between flavours.

Our selection includes classics alongside more distinctive patisserie flavours such as Medovik Honey Cake, Chocolate Fudge, Victoria Celebration, Red Velvet, Black Forest, Tiramisu, Passion Fruit, Carrot & Walnut and Amandina.

Some cakes involve multiple sponges, mousses, creams, curds or other components that require considerably more preparation than a simple sponge cake.

Decoration

Decoration is another major factor in the price.

A beautifully finished classic cake with a personalised message will normally cost less than a cake requiring handmade chocolate flowers, macarons, fresh berries, intricate piping or extensive bespoke decoration.

If you don't require a particular theme, choosing one of our established celebration cake designs is usually the simplest and most cost-effective option.

Bespoke Design

A completely bespoke cake is different from choosing a cake from an existing collection.

Specific themes, unusual shapes, detailed handmade decorations and complex designs require additional planning and production time. For these cakes, we recommend contacting us with your ideas and, where possible, an inspiration photograph so that we can provide an individual quotation.

Ready-to-Order or Bespoke Birthday Cake?

For many celebrations, a ready-to-order cake is the easiest option.

You can choose the cake, select the number of guests, choose your flavour and add personalisation before ordering online.

This works particularly well when you love the style of our existing cakes but simply want to personalise one for your celebration.

A bespoke cake is more appropriate when you have a very specific design, theme or structure in mind.

Both can create a beautiful centrepiece — the important thing is choosing the right option for your celebration and budget.

Why Do Artisan Cakes Cost More?

A handmade patisserie cake is very different from a mass-produced supermarket cake.

The price reflects not only the ingredients, but also the hours of skilled work involved in preparing individual sponges, creams, mousses, fillings, decorations and finishing the cake by hand.

At Prestige Patisserie, our focus has always been on flavour as much as appearance. We use professional pastry techniques and make our cakes from scratch in our North London kitchen.

Our work has received 13 Great Taste Awards, and we were semi-finalists on Bake Off: The Professionals 2021.

How Far in Advance Should I Order?

For our standard celebration cakes, we generally recommend allowing at least 48 hours.

For bespoke cakes, larger celebrations or more complicated designs, contact us earlier so we can confirm availability and discuss what is possible.

During particularly busy periods, giving us additional notice is always helpful.

Collection of Your Birthday Cake

Our cakes are made for collection from Prestige Patisserie in North London.

We don't operate a standard cake delivery service. However, if you prefer not to collect personally, you're welcome to arrange your own courier or private driver to collect the order on your behalf.

Choosing the Right Cake for Your Budget

You don't necessarily need an elaborate bespoke design to have a memorable birthday cake.

Start with three questions:

How many people do I need to serve?
Which flavours do I enjoy?
Do I want one of the patisserie's signature designs or something completely bespoke?

Once you know those answers, choosing the right cake — and understanding the likely cost — becomes much easier.
