TL;DR — Pest Proofing Cost At A Glance
- Most people pay £150 – £600 for professional pest proofing outside London, with larger homes and multiple entry points at the top end; London and the South East run 20–30% higher (inc VAT).
- Pest proofing is a property-protection job — sealing the gaps, vents, pipework and roofline that let rodents, birds and insects in, so infestations stop returning.
- Price depends on the number and type of entry points, the materials used, the height and access of the work, and the size of the property.
- A survey identifies every gap first; a small job may be a handful of sealed entry points, while a whole-home proofing package covers the roofline, air bricks, pipe runs and doors.
- Proofing after treatment is what stops you paying for the same rat or mouse problem twice.
- A BPCA-qualified technician knows that a mouse fits through a 6mm gap and a rat through 20mm, so they seal what an untrained eye would walk past.

How Much Does Pest Proofing Cost In 2026?
Professional pest proofing in the UK costs £150 – £600 on average, rising 20–30% in London and the South East (inc VAT). A small job sealing a few entry points sits at the lower end, while a whole-home package covering the roofline, air bricks, pipe penetrations, doors and drains lands towards the top.
Proofing is about protecting the building fabric rather than killing pests. Rodents, squirrels, birds and insects get in through gaps you would never notice — a worn door sweep, an open air brick, the point where a soil pipe passes through a wall, or a missing roof tile. Sealing those gaps with the right materials keeps pests out permanently, which is why proofing is almost always the sensible follow-up to a treatment. Clear the infestation, then close the door behind it.
Here is what you can expect to pay for pest proofing across the UK:
| Scope of work | Rest of UK | London & South East |
|---|---|---|
| Small job (a few entry points) | £150 – £250 | £180 – £320 |
| Medium job (multiple gaps, one elevation) | £250 – £400 | £320 – £520 |
| Whole-home proofing package | £400 – £600 | £520 – £780 |
| Add-on with treatment | From £100 | From £130 |

Pest Proofing Cost By Entry Point And Method
Proofing is usually priced by what needs sealing and how it is done. The materials matter — cheap fillers get gnawed straight through, while steel wool, wire mesh, mortar and purpose-made covers hold up against determined rodents.
| Proofing task | Typical price (rest of UK) | Typical price (London) |
|---|---|---|
| Air brick / vent cover | £30 – £60 each | £40 – £80 each |
| Sealing pipe or cable penetrations | £40 – £90 per run | £50 – £120 per run |
| Door sweeps / brush strips | £40 – £80 per door | £50 – £100 per door |
| Roofline / eaves and soffit gaps | £150 – £400 (access-dependent) | £180 – £520 |
| Drain and gully guards | £40 – £100 each | £50 – £130 each |
| Full survey and proofing plan | Often credited against work | Often credited against work |
Roofline and eaves work is the biggest single variable, because it often needs ladders, a tower or a platform for safe access at height, which adds to labour. Ground-level sealing is faster and cheaper.
What Affects The Cost Of Pest Proofing?
Several things decide where you land in the ranges above.
1. The Number Of Entry Points
Proofing is priced largely by how many gaps need sealing. One worn door sweep is a quick job; a property with open air bricks, gaps along the eaves, unsealed pipe runs and a damaged roofline needs far more work and materials.
2. The Type Of Pest Being Excluded
The gap size that matters depends on the pest. Mice slip through 6mm, rats through 20mm, and squirrels and birds exploit roofline gaps and broken tiles. Excluding larger pests can mean heavier-duty mesh and covers.
3. Height And Access
Ground-level sealing is straightforward. Roofline, eaves and chimney proofing needs safe working at height — ladders, a scaffold tower or a platform — which adds labour and sometimes equipment hire.
4. Materials
Durable materials cost more but last. Steel wool, galvanised wire mesh, mortar, purpose-made air-brick covers and metal door sweeps resist gnawing far better than foam or sealant, and a good technician prices for materials that will not be breached within a season.
5. Property Size And Age
Larger and older properties have more potential entry points — more air bricks, longer pipe runs, more roofline and often original features that have loosened over time. That means more to survey and seal.
6. Your Location
London and the South East run roughly 20–30% higher than the rest of the UK, reflecting higher labour, travel and access costs.
What's Included — And What's Not
Typically included in a pest proofing quote:
- A survey to identify every entry point
- Sealing gaps with appropriate, durable materials
- Fitting covers, guards, mesh, door sweeps and vent screens as needed
- A summary of the work done and any areas to monitor
Usually charged separately or not included:
- Treatment of an existing infestation (proofing keeps pests out, it does not clear those already inside)
- Major building repairs such as re-rendering, retiling a roof or roofing and guttering work
- Scaffolding for extensive roofline work
- Interior repairs to damage already caused by pests
Always get the list of entry points and materials in writing, so the final bill matches the quote.
Can You Do It Yourself?
Simple, ground-level proofing is within reach of a confident DIYer. Fitting a metal door sweep, screwing on an air-brick cover, packing accessible gaps with steel wool and sealant, and blocking obvious holes will close off the easy routes for the cost of the materials.
Where a professional is worth the money is in finding every gap and reaching the difficult ones. Rodents exploit entry points most people never think to check — the roofline, the point where cables enter, the underside of eaves. A BPCA-qualified technician surveys the whole building, works safely at height, and uses materials that will not be gnawed through in weeks. If you have an active infestation, if the work involves the roof, or if pests keep getting back in despite your best efforts, professional proofing is the reliable fix.
How To Save Money On Pest Proofing
- Do the easy jobs yourself — door sweeps, accessible air-brick covers and ground-level gaps — and leave the roofline and height work to a professional.
- Proof straight after treatment so you do not pay for the same infestation returning.
- Bundle proofing with treatment in one booking rather than paying two separate call-outs.
- Deal with all entry points at once — sealing five gaps and leaving one open simply lets pests back in, wasting the whole job.
- Keep the surrounding area tidy — cut back climbing plants, clear rubbish and store food securely — so the property is less attractive in the first place.
- Get 2–3 quotes and compare the materials and the entry-point list, not just the price.
How To Hire A Good Pest Controller
Choose a firm that employs BPCA-qualified or RSPH-certified technicians, holds public liability insurance, and gives a written quote listing the entry points and materials. Ask how they will survey the property, what they will use to seal each gap, and whether the work carries any guarantee. For roofline jobs, confirm how they will access the height safely. Reviews and references are worth checking before you commit.

Frequently Asked Questions
How Much Does Pest Proofing Cost In The UK?
Professional pest proofing costs £150 – £600 across most of the UK, with whole-home packages at the top end. London and the South East run roughly 20–30% higher (inc VAT). The number of entry points is the main factor.
Is Pest Proofing Worth It?
For anyone who has had an infestation, yes. Treatment clears the pests inside, but without proofing the same gaps let a new population in. Sealing entry points protects the property long term and usually costs less than repeated treatments.
What Is The Difference Between Pest Control And Pest Proofing?
Pest control removes an active infestation; pest proofing seals the entry points so pests cannot get back in. The two work best together — treat first, then proof to keep the building protected.
How Small A Gap Can Mice And Rats Get Through?
A mouse can squeeze through a gap of around 6mm and a rat through about 20mm. Because the openings are so small, proofing focuses on sealing every gap thoroughly rather than just the obvious holes.
Does Pest Proofing Come With A Guarantee?
Many firms guarantee their proofing work for a set period, returning free if a sealed point fails. Confirm the length and terms in writing before booking.
Is Pest Proofing More Expensive In London?
Yes. Expect to pay roughly 20–30% more in London and the South East than in the rest of the UK, reflecting higher labour, travel and access costs.
